Hello, And so another year is drawing to a close

with this our final bulletin for 2019. It has been a big

year for our group with the changing of the guard

from Hamish to myself, and there is plenty of work

to get through with the change to PNZ unified model

in our sights in 2019. As a SIG we are proud to

announce that we finished this year with 1015

members, which as far as we know is the first time

in history that a PNZ SIG has had over 1000

members. So thank you to our members for being

part of SEPNZ.

Its been another busy couple of months for our

executive with our face to face meeting in early

November at the Trinity Hotel in Tauranga to check

out the venue and prepare for the biannual

symposium in March. Justin and I also attended the

PNZ leadership day in late November which was a

great chance to meet up with the other SIG's,

branches and PNZ executive. We are excited to see

the role out of the practitioner side of the PNZ

website and the new market campaign if you

haven't seen it "Don't say oh, say physio". The last

bulletin we ran the photo competition for the cover

of BJSM and although there wasn't a huge timeline

to get entries in, we did receive 12 entries and we

will be announcing the winner of this shortly.

In this issue, we focus on and celebrate our

students and their enthusiasm for our profession.

This bulletin brings together a mix of our new

graduates, and postgraduate students to show that

life long learning is alive and well in our profession.

Rebecca Peace a postgraduate student for Otago

University contributes to this bulletin with her

literature review of the use of cold-water immersion

as a recovery strategy in rugby union and she

comments on the most beneficial protocol to use

with this population. Rebecca Blyth is currently

working towards Masters of Sports Physiotherapy at

the University of Otago, and her review explores the

research behind adductor strengthening for the

prevention of groin injuries in footballers with some

clinical exercises which would be of benefit to your

football players.

Last week Bharat, Justin and Michael from the

SEPNZ executive attended the AUT student prize

giving for the 4th Year students to award the

SEPNZ prize for the best individual contribution in

the fields of sports, exercise and recreation to

Matthew Weir. Congratulations Matthew!

We never stop learning and every 6 months we

offer up the ASICS Education Fund. In August Tom

Adams, as part of his PhD at AUT, received this

award to assist in his research in shoulder

instability. Well done Tom we look forward to your

upcoming thesis. The next round for this grant

closes in March 2019.

Pip Sail adds an article review on the risk factors

for, and prevention of, shoulder injuries in overhead

sports. Also, there is an interesting App review from

Justin Lopes. I am unsure of its clinical relevance,

however, it's a handy app to have and can be used

in many different contexts, so it's worth exploring.

For some, this time of the year is used to reflect and

make a plan for the year ahead and for others it is

just surviving the Christmas parties and getting on

holiday with family and friends. From all on the

SEPNZ executive, we wish a safe and Merry

Christmas and we hope that your plans include a

possible trip to Tauranga for our symposium in

March. The majority of our program and speakers

are confirmed. Please be aware that the early bird

rate closes at the end of January for this, for more

information please check out our website for the up

to date agenda and booking information. Enjoy

your summer, and see you in 2019 in Tauranga.

Noho ora mai

Kind Regards

Blair Jarratt

GET TO KNOW THE TEAM - 2 MINUTES WITH...

Blair Jarratt

SEPNZ President

What role do you play on the exec? President – I took over this role from Hamish Ashton this year. I started on the executive 5 years ago helping to work on the sports physiotherapy contract that members can download in our resources section of the website and later looked after the website. Life outside of SEPNZ? My wife Sheree and I have two children - Ashton aged 9 and Pippa aged 7 and we live in Tauranga. I am the co-director of Bureta Physiotherapy in Tauranga with 18 staff, at this time of the year on the weekends the family will be at the beach. All year and when I have some time (usually ridiculously early in the mornings) you will find me out on the mountain bike as we have a pretty good bunch of riders here in Tauranga that get out 3 times a week. Previous teams worked with / sporting background....and present? I cut my teeth on sports physiotherapy pretty early on in the piece starting off when I was a Otago student with University Rugby, then more stints in Rugby in Canterbury working with High School Old boys, Sydenham, Canterbury Metro, and finally into Canterbury Rugby. Also while in Canterbury I worked with Canterbury Cricket, and the Canterbury Wizards for a number of years. I toured with NZ U19 Cricket to Australia and then onto the U19 world cup in Dubai. Currently I work with the Mount Surf Life Saving Club who are currently in full swing for the season and also help out with our staff that work with some of the Bay of Plenty's top rugby club’s - Mount Maunganui Rugby and Te Puna Rugby Favourite tune on a roadtrip? Most of the road trip tunes are pretty dominated by the kids around this time of year, Pippa is pretty relentless at pumping the Christmas carols, however I try to slip a few Dad tunes in. I am enjoying the new rendition of “Africa" by Weezer. Favourite sporting physiotherapy moment? Wow….. tough question I’m not sure I have a favourite moment, being part of a winning team is always exciting but in sport there is always winning and losing and good things to take away from both. Working in the management of a team and helping getting players back into what they love doing after significant set backs and injuries is always rewarding. Favourite/best or worst destination as touring Physio and why? . Working in Forsyth Barr Dunedin stadium for the Canterbury and Otago Rugby final was a pleasure as it was pouring down outside but Dubai was a eye opener for a place to Tour.

CLINICAL REVIEW

By Pip Sail, PhysioFix

Shoulder injuries and shoulder pain are substantial problems in

overhead athletes. This problem highlights the need for injury

prevention strategies. Identifying risk factors and developing

injury prevention strategies based on these risk factors are key

components for preventing injury in sport.

A common feature of overhead sports is the repetitive use of

the shoulder with the hand above the head. There may be sex

and age differences as observed in other anatomical sites in

other sports8,18,19 and contact sports may be at higher risk.

Biomechanical factors such as shoulder mobility, coordination

and poor technique may also be factors.

Overhead sport is defined as a sport in which the athlete, with

the forearm/hand , repetitively propels a ball or shuttle against

an opponent.

The principle findings from the systematic review were that the

studies were of poor quality, the results were inconsistent and

most risk factors had only been explored in one study.

Investigating modifiable risk factors, such as biomechanical,

physiological, and psychological measures alongside

modifiable training factors is required to develop successful

injury prevention measures. This asks the question whether

practitioners should be considering performance and return to

play parameters rather than an injury prevention perspective.

Abstract: To assess the evidence for risk factors and prevention measures for shoulder injuries and the effect

of primary shoulder injury prevention measures in overhead sports by systemic review.

What should the practitioner do?

Practitioners should strive to build their work on evidence-based medicine. This means integrating individual clinical

expertise with the best available external clinical evidence from systematic research.78

Since there is little evidence to suggest that shoulder screening for injury prevention is effective79 the main purpose should

be to evaluate current shoulder status, measure improvements in performance and serve as normative values to attain before

return to play after injury.79-81 When the evidence is limited look for position statements and expert panel opinions.77

Conclusions:

All investigated risk factors for shoulder injury in overhead ports had limited evidence, and most were non-modifiable

(eg,sex). There is also limited evidence for the effect of shoulder injury prevention measures in overhead sports.

Does an

ADDUCTOR STRENGTHENING PROGRAMME

INCREASE adductor strength

PREVENT adductor-related groin injuries in football?

Groin injuries are one of the most prevalent injuries in football accounting for 8-18% of all injuries (Esteve,

Rathleff, Bagur-Calafat, Urrútia, & Thorborg, 2015; Serner et al., 2014). Adductor injuries account for over 60% of

groin injuries, resulting in adductor injuries being the second most common injury in football (Ishøi et al., 2016;

Jensen et al., 2014). Preventing adductor injuries is crucial in football not only because of the high incidence but also

due to the time-loss associated with the injury; 40% of adductor injuries experience more than 28 days absence from

football (Ishøi et al., 2016). Several studies have suggested that along with previous adductor injuries and increased

age, reduced adductor strength is a risk factor for sustaining an adductor injury while playing football (Engebretsen,

Myklebust, Holme, Engebretsen, & Bahr, 2010; Esteve et al., 2015; Ryan, DeBurca, & Mc Creesh, 2014). It has been

well documented that specific adductor strengthening programmes show an increase in adductor strength, with

increased eccentric strength being of particular importance (Harøy et al., 2017; Ishøi et al., 2016; Jensen et al., 2014).

There is conflicting evidence surrounding whether the increase in adductor strength relates to a reduced injury risk.

The aim of this critical review is to review the risk factors for adductor injuries, to review if adductor strengthening

programmes increase adductor strength and explore if increased adductor strength reduces adductor-related groin

injuries in football.

Risk Factors

Risk factors for adductor injury can be either non-

modifiable or modifiable. The two most significant non-

modifiable risk factors in predicting adductor injury are a

previous adductor injury and increased age (Arnason et al.,

2004; Engebretsen et al., 2010; Ryan et al., 2014).

PAGE 12

FEATURE ARTICLE

Although previous adductor injuries are a non-modifiable

risk factor, as football players having had previous

groin injuries are up to seven times

more likely to sustain a subsequent

injury (Arnason et al., 2004) it is

reasonable

to consider primary prevention

of utmost importance

(Engebretsen et al., 2010).

Weakness of the hip

adductor muscles is

considered the

most significant modifiable intrinsic risk factor for

adductor injury (Engebretsen et al., 2010).

Engebretsen et al. (2010) carried out a prospective cohort

study that concluded weak hip adductors increased the risk

of groin injury by four times. However, this disagrees with

a study suggesting that having higher maximal power was

more likely to be associated with a groin injury (Arnason

et al., 2004). The disparity between the two studies results

is likely due to the difference in measurement methods.

Engebretsen et al. (2010) used a specific measurement of

isolated adductor strength using hand-held dynamometry

while Arnason et al. (2004) measured power using a squat

and jump test. Likely due to the increased specificity of

the measurement in Engebretsen et al. (2010), it has been

widely accepted in the literature that reduced adductor

strength is a risk factor for groin injury (Ryan et al., 2014).

Further supporting the notion that reduced adductor

strength is a risk factor for adductor-related groin injuries

is a study that measured pre-season adductor strength in

those with and without past-season groin pain (Esteve et

al., 2018). This cross-sectional study concluded that

athletes who had more than six weeks of groin pain in the

previous football season had significantly reduced

adductor strength (Esteve et al., 2018). This highlights a

link between previous injury and reduced adductor

strength. Although a previous groin injury is the most

significant risk factor, part of this may be due to

inadequate rehabilitation and therefore reduced adductor

strength when returning to play. Esteve et al. (2018) also

found that athletes with current groin pain had a 10%

reduction in adductor strength in the adductor squeeze test.

This is in line with a study from the Australian football

league who showed that adductor strength was reduced

both before and during the onset of groin pain (Crow et al.,

2010). Considering the weakness could be identified in the

weeks preceding groin pain or injury it is reasonable to

suggest that reduced adductor strength is a measurable

and modifiable risk factor (Crow et al., 2010). In

agreement with these two studies is a meta-analysis that

suggested that pain and reduced strength on the

adductor squeeze test was more likely in athletes

with hip and groin pain (Mosler, Agricola, Weir,

Hölmich, &

Crossley, 2015).

An assessor blinded

study strengthens

this finding showing that football players with

adductor related groin pain had significant eccentric

adductor weakness when compared to matched

asymptomatic controls (Thorborg et al., 2014). The

blinding of this study is a strength as when using a hand-

held dynamometer, clinicians may subconsciously adjust

the pressure they are applying if they know which

participants are in the pain group versus the control group.

The agreement surrounding groin pain reducing adductor

strength and adductor weakness increasing injury risk is

convincing, the studies discussed above are well-designed

cross-sectional and cohort studies which provides

clinicians confidence in interpreting the results. It is

important to understand the risk factors for adductor-

related groin injuries when trying to provide preventative

strategies to reduce injury rates.

FEATURE ARTICLE

Adductor Strengthening Programmes

Adductor strengthening programmes have been suggested as a solution to reducing groin injuries as they aim to

strengthen the hip adductor muscle group. As football involves eccentric adductor strength during kicking, there has

been suggestion that eccentric adduction weakness should be targeted in football injury prevention programmes

(Ishøi et al., 2016; Jensen et al., 2014; Thorborg et al., 2014). A study comparing elite football players to matched

recreational athletes showed that football players had increased eccentric hip abduction strength, however there was

no significant difference in eccentric hip adduction strength (Thorborg, Couppé, Petersen, Magnusson, & Hölmich,

2011). This was a surprising result, but suggests that playing football does not induce eccentric hip adductor

strength increases and therefore this is an area that needs to be targeted in off-field training (Thorborg et al., 2011).

There has been good success in using eccentric exercises to reduce hamstring injuries in football (Al Attar, Soomro,

Sinclair, Pappas, & Sanders, 2017) but the success of similar eccentric programmes in adductor injuries have not

been so extensively researched.

Adductor Strengthening and

Increased Adductor Strength

Table 1 above summarises three studies that investigated

the effect of an adductor strengthening programme on

adductor strength. The three studies reach consensus that

performing an 8-week adductor strengthening programme

does increase adductor strength, although there was

variation in the strength increases and the adductor

exercises prescribed. All three studies were randomised

control trials providing high level evidence. Ishoi et al.

(2016) found the largest increase in adductor strength using

the Copenhagen adductor (CA) exercise, it was a well-

designed randomised control trial with excellent

compliance rates. Haroy et al. (2017) used the same CA

exercise, however was different to the previous study as

the exercise was incorporated into the Federation

Internationale de Football Association (FIFA) 11+ in place

of the Nordic hamstring exercise. The strength increase

was much smaller although was still significant and this

study is particularly relevant as the FIFA 11+ is widely

recognised and used by football teams of all levels. The

CA exercise targets eccentric strength at the same time as

also having isometric and concentric components, Figure 1

shows the CA exercise being performed. A possible

FEATURE ARTICLE

reason for the large difference in the strength increase

despite using the same exercise is the dosage of the

exercise programme. Ishoi et al. (2016) used greater sets

and repetitions than Haroy et al. (2017) resulting in a

difference in the total number of repetitions completed.

This suggests that there is a dose-response correlation with

increased volume of exercise inducing a greater strength

improvement. Jensen et al. (2014) showed a 30% increase

in adductor strength, similar to that of Ishoi et al. (2016)

using 8-weeks of elastic band exercises. This study also

asked the athletes to work through a slow and controlled

eccentric phase with the bands to target eccentric strength.

The three studies all show that with the use of minimal

equipment and simple exercises, it is possible to get a

meaningful increase in hip adductor strength.

Adductor Strengthening and

Reducing Adductor-related

Groin Injuries Table 2 summaries two studies that directly investigated

the effect of adductor strengthening on the incidence of

groin injuries in football players. Both studies showed a

reduction in the number of groin injuries, however only

one of the studies reached statistical significance. Both

studies were of good methodological design with a large

sample size and randomisation protocols. The two studies

differed significantly in their intervention programme.

Haroy et al. (2018) used the CA exercise or suitable

regressions exclusively in comparison to Holmich, Larsen,

Krogsgaard, & Gluud (2010) which asked the athletes to

complete six different exercises targeting the adductors,

core strength and coordination. The 31% reduction in

injuries in the Holmich et al. (2010) study seems a large

reduction but didn’t reach significance. This is due to

basing the sample size on a 50% injury reduction rate and

having difficulty getting clubs to remain in the trial for its

entirety. Coaches were asked to supervise the players,

however there was no direct measure of compliance, this is

a potential reason significance was not met as the players

may not have been completing the prescribed exercises. In

comparison, compliance in the Haroy et al. (2018) study

was good and they performed two separate analyses on

varying levels of compliance. They found that increased

compliance led to a greater reduction in injury risk, in

agreement with the dose-response relationship discussed

above; those with excellent compliance almost halved their

injury risk, however both groups reached significance.

The compliance rates are likely due to having only one

exercise which is easy for the athlete to perform. It may be

seen as isolating to adductor related groin injury only, but

as this accounts for the majority of all groin injuries, it is

the most important area to address (Harøy et al., 2018).

Along with the excellent compliance rates, Haroy et al.

(2018) implemented the strengthening programme in the

FEATURE ARTICLE

preseason to gain a strength effect before injury counting

in the competition started. This early implementation

would appear to have had significant benefit in reducing

the rate of injuries.

Although the studies discussed in Table 1 did not directly

measure the injury rates and therefore cannot explicitly

state that adductor strengthening prevents injury, they all

hypothesised with the increased adductor strength there

would be a reduction in adductor-related groin injuries.

This was a reasonable hypothesis to make considering the

evidence discussed in the risk factor section where

adductor weakness was shown in players with adductor-

related groin pain, and those with adductor weakness were

more likely to sustain an adductor injury.

Discussion

Eccentric adductor weakness is a modifiable risk factor for

adductor-related groin injuries. There is also convincing

evidence that current adductor pain is a risk factor for

adductor injuries in several kicking dominant sports. The

studies tabled above show the benefits of using an adductor

strengthening programme to increase adductor strength and

prevent adductor-related groin injuries in football. This

evidence is echoed in other sports with a high prevalence

of groin injuries, such as ice hockey. A study of

professional ice hockey players identified reduced

adductor strength as a risk factor for injury and found that

an adductor strengthening programme had a preventative

effect on the rate of groin injuries (Tyler, Nicholas,

Campbell, Donellan, & McHugh, 2002).

A common discussion among the articles used in this

review was the reduced eccentric adductor strength in

footballers and the use of eccentric exercises in

strengthening and prevention programmes. The adductor

longus tendon complex is put under high levels of

eccentric stress during football, particularly while kicking

(Jensen et al., 2014). Decreased eccentric adductor longus

strength may compromise the energy absorption of the

tendon and leave it more vulnerable to injury with

increased stress at the adductor longus insertion (Thorborg

et al., 2014). As previously mentioned, eccentric training

has proven effective in increasing eccentric hamstring

strength and reducing hamstring injuries in football (Al

Attar et al., 2017). There has also been research to show

that a rehabilitation programme including eccentric

adductor exercises has proven effective in the management

of adductor-related groin pain (Hölmich et al., 1999).

Until the Haroy et al. (2018) study there was no significant

evidence that adductor strengthening prevented adductor

injuries in football players. There has been great success

in the implementation of the FIFA 11+ programme

worldwide and through all levels of football. This

programme is effective in preventing injuries in football

(Gomes Neto et al., 2017) however there is no exercise

included which targets eccentric adduction strength in the

FIFA 11+ model. This has been identified as a gap in the

warm up and training programme, with the suggestion of

the CA exercise to be added to the FIFA 11+ to target the

prevention of adductor-related groin injuries (Harøy et al.,

2017).

An obvious theme throughout the studies included in this

review was the use of the CA exercise. The CA exercise

has excellent clinical applicability being a partner exercise

that requires no equipment and can be completed on the

training pitch. Several of the studies also reported that

there was no associated harm or risk when performing the

CA exercise during their studies (Harøy et al., 2018; Harøy

et al., 2017; Ishøi et al., 2016). An electromyography

(EMG) study found that the CA exercise, band adduction

and the adduction machine were all considered high

intensity adductor exercises with high EMG activity of

adductor longus and an eccentric component (Serner et al.,

2014). Considering the eccentric adduction weakness

highlighted in football players, these exercises are

potentially the best exercises to use for injury prevention

(Serner et al., 2014). This hypothesis has been proven by

studies showing the use of the CA exercise and band

exercises have increased eccentric adductor strength and

had an effect on the reduction of adductor related groin

injuries (Harøy et al., 2018; Harøy et al., 2017; Ishøi et al.,

2016; Jensen et al., 2014).

The findings of this review do have some limitations, with

the main one being the populations studied. Although

there has been a variety of levels of football players

included all have been youth and adult male players,

therefore generalisability to female and children playing

football remains unknown. However, male football

players do have the highest prevalence of groin injuries,

hence the use of this population in the studies reviewed.

Conclusion

There is consensus in the literature that adductor-related

groin injuries are highly prevalent in football and first line

prevention is crucial due to the time-loss associated with

the injury and the high rate of re-injury. There is evidence

to suggest that eccentric hip adductor weakness is

prevalent in football players. A strengthening programme

consisting of eccentric adductor exercises has proven to

increase eccentric adductor strength and reduce the rate of

adductor-related groin injuries in football players. The CA

exercise has shown success and is a promising exercise for

the prevention of groin injuries as it can easily be

performed pitch side or as part of the FIFA 11+

programme.

Introduction

With the ever increasing demands of competition scheduling and training loads in team sports such as rugby union,

research into optimal recovery strategies is continuing to evolve (Tavares, Smith, & Driller, 2017). One such recovery

method is the use of cold-water immersion or ice baths. Cold-water immersion therapy (a form of cryotherapy) by

definition is the application of ice or extreme cold to the body to treat injury and/or aid a rugby athlete’s return to sporting

performance (Higgins, Cameron, & Climstein, 2013; Stephens et al., 2018).

The aim of this literature review is to investigate the current evidence regarding cold-water immersion as a method of

performance recovery by means of its physiological effects and best application technique in rugby union.

Demands and effects of rugby union

Rugby union is a high paced game involving full contact

collisions, as well as high intensity aerobic and anaerobic

activity with short periods of rest (Garcia, da Mota, &

Marocolo, 2016; Adamczyk, Krasowska, Boguszewski, &

Reaburn, 2016; Barber, John, Brown, & Hill, 2017). Over

the course of a standard rugby season, athletes cycle

through periods of training, game time and recovery

sessions (Higgins, Climstein, & Cameron, 2013; Higgins,

Heazlewood, & Climstein, 2011; Higgins, Cameron, &

Climstein, 2013). Tight turn around time between each

session may not provide the athletes with sufficient time to

recovery to pre-session performance levels (Higgins,

Cameron, & Climstein, 2012; Barber et al., 2017). As

result, accumulative performance stresses on the body may

lead to increasing fatigue levels, muscle micro-damage and

muscle soreness, as well as declines in power and

neuromuscular function (Garia et al., 2016; Adamczyk et

al., 2016; Higgins et al., 2011; Chow, Yam, Chung, &

Fong, 2017).

The most commonly discussed consequence to repeat

performance stress in the literature is Delayed Onset

Muscle Soreness which develops in response to muscle

tissue micro-damage, inflammation and elevated lactate

levels produced by the exercising muscles (Higgins,

Cameron, & Climstein, 2013; Adamczyk et al., 2016).

Symptoms of delayed onset muscle soreness peak at 24-48

hours post-exercise and include: pain, muscle soreness and

tenderness, loss of muscle power, decreased flexibility and

in some cases muscle swelling or oedema (Higgins,

Cameron, & Climstein, 2013; Adamczyk et al., 2016;

Garia et al., 2016).

At a physiological level, a decline in neuromuscular

function occurs as a result of delayed onset muscle

soreness (Takeda et al., 2014). In a study by Takeda et al.,

2014, it was documented that knee extensor force output

activity decreased following eccentric exercise. It was

postulated that muscle damage as a result of exercise, in

particular damage to fast twitch muscle fibres, may lead to

changes in temporal and local muscle recruitment patterns,

as well as an increase in time required to reach peak

muscle velocity (Takeda et al., 2014).

The resultant detrimental impact on a rugby athlete’s

performance emphasises the need for in season

interventions, such as cold-water immersion, to fast track

the athlete’s post-performance recovery (Chow et al.,

2017; Barber et al., 2017).

Physiological effects of cold application

Cold-water immersion post-exercise produces a variety of

local and systemic effects. Firstly, the introduction of cold

triggers an initial vasoconstriction response in local blood

vessels that is shortly followed by vasodilation 2-6 minutes

later (Adamczyk et al., 2016). Increased filling of blood

vessels via vasodilation and, therefore, the ventricles of the

heart, significantly changes systemic cardiovascular

parameters (such as stroke volume), promoting blood flow

and oxygen delivery to recovering muscles (Adamczyk et

al., 2016; Garia et al., 2016).

Second, application of cold assists in the modulation of

local muscle micro-damage. During exercise, core and

muscle temperatures increase as a result of exertional heat

(Chow et al., 2017). Increase in temperatures promotes

enzymatic breakdown of muscle fibre structure, shown by

increased blood concentrations of serum creatine kinase

(Higgins, Cameron, & Climstein, 2013; Banfi, Melegati, &

Valentini, 2007; Adamczyk et al., 2016). In the study by

Banfi et al. (2007) it was reported that application of cold-

water immersion in conjunction with active recovery

(cycling) significantly reduced serum creatine kinase levels

post intervention compared to passive recovery (resting at

room temperature). Similar findings were reported by

Barber et al. (2017) where serum creatine kinase

FEATURE ARTICLE

concentration was significantly blunted 24-48 hours post

application of cold-water immersion.

Heating and its associated metabolic processes may also

impair joint proprioception via changes in somatic sensory

input (Chow et al., 2017). In the study by Chow et al.

(2017) it was concluded that the application of cooling,

both at room temperature and with ice, improved post-

exercise proprioception; as long as cooling was not to

extreme temperatures.

Thirdly, use of cold aids in the reduction of skeletal muscle

inflammation post exercise. Locally, cold causes a

decrease in capillary permeability, thus reducing fluid

diffusion into the interstitial space of the muscle that

causes swelling/oedema (Barber et al., 2017). A decrease

in capillary permeability reduces inflammatory cell

infiltration, thereby lessening the muscle cell breakdown

that causes muscle micro-trauma (Higgins, Climstein, &

Cameron, 2013; Adamczyk et al., 2016; Barber et al.,

2017; Tavares et al., 2018).

Fourthly, cooling assists in modulation of neural pathways

and the sensation of pain. As previously discussed, cold

reduces muscle oedema, therefore decreasing compression

and irritation of skeletal muscle free nerve endings (Barber

et al., 2017). Likewise, the reduction in local muscle

temperature reduces receptor sensitivity, nerve conduction

velocity, muscle spindle afferent signalling and stretch

reflex responses required for pain production (Adamczyk

et al., 2016; Barber et al., 2017; Garia et al., 2016; Chow et

al., 2017; Tavares et al., 2018). Cold application promotes

improved parasympathetic activity, aiding the return of the

exercised body to functional and neural homeostasis (Garia

et al., 2016; Stephens et al., 2018).

Finally, as the symptoms experienced with post-exercise

delayed onset muscle soreness incorporate all of the above-

mentioned components, it is plausible from a physiological

perspective that cold therapy, such as cold-water

immersion, could be beneficial for the management and/or

prevention of delayed onset muscle soreness following a

rugby session.

Cold-Water Immersion Protocols

Protocols for cold-water immersion post rugby game or

training vary across the literature. Rugby union is highly

demanding of the lower limbs for explosive take offs,

running, direction changes and pushing in scrums. As

shown in Table 1, the majority of research immerses the

athlete’s lower limbs to the level of the iliac crest or

superior iliac spine.

The most common protocol used an immersion depth to

the superior iliac spine, a temperature range of 10-12°C

and a time of two sets of 5 minutes with a 2.5 minute rest

between. All included studies that used the temperature

range of 10-12°C, demonstrated beneficial findings in

support of cold-water immersion.

Immersion temperatures range from 5°C to 15.9°C, with

the average temperature being 10.8°C. Stephens et al.

(2018) used the highest temperature of 15.9°C and had the

longest immersion time of 15 minutes. In contrast Chow

et al. (2017) used the lowest temperature of 5°C but had

the shortest immersion time of 1 minute. This study‘s

findings demonstrated a greater detrimental effect on knee

proprioception when compared with room temperature

water immersion; whether this detrimental effect was as a

result of the cooler temperature or the short duration of

immersion is unknown.

Three studies used whole body immersion, excluding the

head. Lindsay, Lewis, Gill, Gieseg, & Draper (2015) and

Takeda et al. (2014) reported inconclusive findings. In

comparison, Stephens et al. (2018) demonstrated positive

effects on recovery only in athletes with a high body fat percentage.

Variability in research findings could be attributed to several factors, including sample size and make up (for example,

professional level rugby players verses under 20 year olds), different immersion levels and temperatures, duration and

repetition of immersions, as well as the pre and post immersion measurements used (for example, perceived level of

soreness verses counter-movement jump or blood creatine levels).

Effects of CWI on performance

and Muscle Soreness

Subjective Measures

The primary outcome measure used across the literature to

measure the effectiveness of cold-water immersion is an

athelete’s level of perceived muscle soreness (Higgins,

Climstein, & Cameron, 2013; Banfi et al., 2007; Barber et

al., 2017). All three studies that used the immersion

protocol of 2x5 minutes with a 2.5 minute break, reported

positive changes in both the athlete’s perceived level of

muscle soreness and delayed onset muscle soreness

symptoms (Higgins, Cameron, & Climstein, 2012;

Higgins, Cameron, & Climstein, 2013; Higgins, Climstein,

& Cameron, 2013).

As previously discussed, application of cold has a positive

physiological effect on the sensation of pain. Given that

symptoms of delayed onset muscle soreness peak at 24-48

hours post exercise (Adamczyk et al., 2016), outcome

measures for delayed onset muscle soreness need to be

assessed over this timeframe. Higgins, Cameron, &

Climstein (2013) followed rugby athletes over a 48-hour

period post cold-water immersion and reported a

statistically significant finding in regards to pain at 48

hours. Post cold-water immersion muscle pain scores had

reduced to 13% compared to 20% of baseline in the control

group. Webb, Harris, Cronin, & Walker (2013) and

Tavares et al. (2018) similarly reported the most beneficial

effects on muscle soreness occurred 18-42 hours post cold-

water immersion.

Over the course of a heavy training week, a reduction in

perceived muscle soreness resulted in positive effects on a

rugby athlete’s perception of fatigue and overall training

effort (Higgins, Cameron, & Climstein, 2013; Higgins,

Climstein, & Cameron, 2013; Takeda et al., 2014; Barber

et al., 2017).

Physiological measures

The effect of cold-water immersion on physiological

markers, such as serum creatine kinase, skin and/or core

temperature and thigh circumference, gives an objective

measure of effect on the rugby athlete’s physiological

performance recovery. Minimal to no effect was

documented on salvia cortisol levels (Tavares et al., 2018).

Blood serum creatine kinase recovery varied across the

literature, with several studies reporting faster stabilisation

post cold-water immersion (Banfi et al., 2007; Barber et

al., 2017; Tavares et al., 2018) and another reporting no

effect compared to a control group (Takeda et al., 2014).

All studies reported significant reductions in skin

temperature compared with contrast therapy and control

groups. In the study by Stephens et al. (2018) body

composition (high fat versus low fat participants) was

applied to the protocol of 15 minutes immersed in 15.9°C.

Given that body fat acts as a heat insulator, decline in core

temperature was significantly higher in low fat individuals

(Stephens et al., 2018).

Thigh circumference, as a measure of skeletal muscle

inflammation and oedema, was found to have no

statistically significant difference post cold-water

immersion compared to control groups (Higgins, Cameron,

& Climstein, 2013; Tavares et al., 2018).

Due to inconclusive findings of physiological markers for

measurement of beneficial effect, it is not possible to draw

conclusions as to how much skin or core temperature and

serum creatine kinase levels need to decrease in order to

aid a rugby athlete’s performance recovery.

Functional Measures

Finally, sports-specific or functional measures could be

used to relate level of recovery to the specific demands of

Page 23: Risk factors for, and prevention of, shoulder injuries …...U19 world cup in Dubai. Currently I work with the Mount Surf Life Saving Club who are currently in full swing for the season

FEATURE ARTICLE

rugby. Such measures used across the literature, include

vertical jump height, counter-movement jump tests and

timed sprints or 50m hop tests. Tavares et al. (2018)

reported a small benefit in recovery of neuromuscular

function, with a faster recovery of counter-movement jump

score when compared to passive recovery. Higgins,

Cameron, & Climstein (2013) made a similar conclusion,

reporting an accelerated return of muscle power when

compared with passive or contrast bath therapy.

In contrast, Garcia et al. (2016) reported no change in

counter-movement jump testing; however, they did note a

decline in muscle tests of longer duration (such as a 30

second vertical jump or continuous hop). Likewise,

Higgins et al. (2011) and Takeda et al. (2014) described a

significant detrimental effect on sprint speed during a

timed 50m dash.

Another performance factor that could be influenced by

cold-water immersion is the neuromuscular control of

lower limb balance. As mentioned previously, cold alters

mechanorecpetor sensivity and nerve conduction velocity

(Chow et al., 2017; Tavares et al., 2018). Therefore, cold

could potentially effect lower limb joint position sense

(proprioception) and balance required for hopping and

jumping functional measures. Chow et al. (2017)

conducted a study investigating this exact theory and

concluded the cold-water immersion did decrease knee

joint proprioception to a much greater extent than passive

recovery; however, cold did not alter overall

somatosensory inputs for balance control.

Given the accelerated recovery of sport-specific

neuromuscular function with the use of cold-water

immersion on a rugby athlete ’s recovery, it could be

concluded that within congested periods of rugby (i.e. less

that 48 hours between sessions), cold-water immersion

may aid recovery and performance (Tavares et al., 2018;

Higgins, Cameron, & Climstein, 2013).

Clinical application

To apply the evidence to practice in the rugby environment, as shown above, several factors need to be

taken into account. Firstly, what is the reason for trying to hasten the athlete’s recovery of performance?

What beneficial effect needs to be gained from recovery? Is there concern over muscle power loss or

development of delayed onset muscle soreness? What are the individual athlete’s rugby sporting demands

and how might their body composition contribute? Taking all of these questions and the current best

evidence into account, cold-water immersion should, in theory, have positive physiological and

psychological effects. Out of the studies included in this review, the most beneficial protocol for

application of cold-water immersion seems to be 2x5 minute intervals with a 2.5 minute break of

immersion to the level of the superior iliac spine in 10-12°C water.

If a rugby athlete reports perceived performance enhancements with the use of cold-water immersion, we

should not rule it out as a beneficial technique for aiding recovery. To date, the research has not been able

to define the most effective balance of temperature, time and technique to ensure cold-water immersion is

beneficial for every rugby athlete’s recovery.
