HOW TO USEHPU UNITS INDOORS

HOW TO USEHPU UNITS INDOORS

The HPU units are designed to automatically collect accelerometer and heart rate data in an indoor environment. This allows teams to collect vital indoor information about external and internal mechanical load being exhibited by the athlete in an indoor session.

COLLECTING DATA IN INDOOR MODE

1. Turn on the units whilst OUTDOORS and wait until the unit has started to collect GPS data (Green flashing light on the unit). This will ensure you get an accurate timestamp on your session.

a. NOTE: you can turn on your HPU units INDOORS and the unit will still collect data. However, you will not get an accurate start time for your session

2. Move INDOORS and the unit will continue to collect accelerometer and heart rate data

3. After the session you can then download the data to the docking station as per usual

If there is no GPS data to download and the message ‘Session Empty’ appears, then the download as Indoor function can be used

HOW TO USEHPU UNITS INDOORS

DOWNLOAD INDOOR FUNCTION

1. Place unit in Docking Station

2. Connect Docking station to computer

3. Open Team AMS and go to Downloads

4. Select session and then RIGHT Click on session – Select Download as Indoor

When running INDOOR sessions, ensure “Delete after Download” is unchecked, otherwise if the “Session Empty” message appears, the session will be automatically deleted from the dock.

HOW TO USEHPU UNITS INDOORS

COLLECTING DATA FOR AN OUTDOOR AND INDOOR SESSIONWith the HPU you can begin your session outdoors and move indoors. If this happens, you should download the session as any other outdoor session.

The data downloaded into Team AMS will reflect both the outdoor (GPS, Accelerometer and Heart Rate) and indoor (Accelerometer and Heart Rate only) information.

TEAM AMS SETTINGS SHOULD BE SET FOR “AUTOMATIC INDOOR MODE”It is important to ensure that Team AMS is set up to allow for the software to automatically detect when an HPU is indoors. This can be done by changing the configuration settings.

1. Click File > Configure

2. Select “Distance/Sprint” Tab

3. Select Enable HPU Automatic Indoor

UNDERSTANDING GPSPORTS ANALYSIS

DISTANCEDistance travelled was among the first variables that GPS monitoring systems provided coaches and athletes. Total distance is used by most team sports as a reliable measure of total workload both in real time and post event analysis.

PRACTICAL APPLICATIONSDaily distance and accumulated distance are key variables used to ensure athlete loading is systematic and progressive. Excessive overload of distance often relates to overtraining and load based injuries. Real time distance data is commonly used to alter session length and training content for a team or specific players. Both real time and post event data is critical to manage at risk players and players returning from injury.

DATA SOURCEDistance is derived from the GPS sensor. GPS data is filtered prior to reporting to improve accuracy.

ACCURACY AND RELIABILITYThe accuracy and reliability of GPSports distance data is excellent. Field based trials show error to be in the order of <2 % for post event data.

DERIVATIVESAverage Speed - Distance Per MinuteDistance travelled per minute for a period of an activity is commonly used as a key indicator of work rate. Available live and post event, Distance per minute (metres/min) is used to compare players, drills and positional demands.

Practical applicationsUse Distance per minute to understand game speed, the effect of fatigue, position, drill size and rule changes in practice drills. Understand both the average demands, but more importantly the ‘worst case scenarios’ and then use training interventions to overload these parameters. For example the average speed of a 40 minute period of football may be 110m/min, but short periods of play will be in excess of 160m/min for 3-4 minutes. This is common across many team sports.

GPSPORTS VARIABLES

SPEED ZONE DISTANCE

Distance covered in each speed zone provides a deeper insight into player loading. This variable allows the coach to understand more about the quality or intensity of the training stimulus. Commonly, both low and high speed distances are assessed.

PRACTICAL APPLICATIONSTeams will often have targets set for exposure in each zone as a marker of training load, if these targets are not met, training can be immediately adjusted. The data can be used in a comparative sense to assess the differences in positional and individual characteristics.

Exposure into different zones can be used to indicate either a metabolic or mechanical load. A low speed threshold, similar to a Maximal Aerobic Speed can be used to assess exposure to an adaptive metabolic stimulus, while exposure to high speed running is critical to manage neuromuscular load in particular hamstring load. Many examples have been noted where rapid increases (acute and accumulated) in high speed running loads have been key indicators for soft tissue injury.

CALCULATIONSTeam AMS allows up to 6 speed zones to be created in the Analysis/Zonessection, while SPI Real Time allows 4 zones to be set. Speed zone distance isbased on how much time an athlete spends at a given speed. There is no minimum time requirement to accumulate distance in a zone so fragments of distance will be added to zones as the athlete accelerates and decelerates.

ACCURACY AND RELIABILITYInvestigations have shown speed zone information is more reliable when single thresholds, or wider zones are used. Accuracy is difficult to assess in sports specific movement patterns. Inter unit reliability of HPU units has been demonstrated at <1% error when using single thresholds.

SAMPLE SETTINGSLow Speed Threshold – Total Distance above 3m/s, or 10km/hHigh Speed Threshold - Total Distance above 5m/s, or 18km/hVery High Speed Threshold - Total Distance above 8m/s, or 30km/h

DERIVATIVESAverage Speed - Distance Per MinuteFor Example – High Speed Metres Per Minute. Indicator of the average rate of high speed running throughout the period.

Practical applicationsFor Example - % High Speed Distance. Indicator of the amount of high speed running relative to the total distance travelled.

GPSPORTS VARIABLES

MAXIMAL SPEEDMaximal speed reflects the highest (peak) single speed reported from the GPS sensor during the time period being analysed (session or split).

PRACTICAL APPLICATIONSLess emphasis is generally given the Maximal Speed than Speed Zone Distance information. While this variable in not a marker of quantity of load, it is a valid marker with respect to peak intensity of running.

Commonly used in the longitudinal analysis of individual players. Highly valuable when assessing graded loading of a player during rehabilitation, particularly from lower body soft tissue injury. Pre injury data provides an insight into maximal capacity of the athlete and therefore an objective marker of what needs to be achieved prior to return to play

It is valuable to understand the maximal speeds expected in commonly used drills, this can assist in planning exposures to maximal speed running.

CALCULATIONSMinimal processing, GPS derived speed values must pass our base filtering checks.

ACCURACY AND RELIABILITYHigh.

GPSPORTS VARIABLES

SPEED EXERTIONSpeed Exertion is designed to be a single value to represent both running volume and intensity.

PRACTICAL APPLICATIONSUsed to assess and compare the quality of the running load.

Use the absolute value of Speed Exertion as an integrated volume and intensity marker, or use Speed Exertion per Minute to analyse the high intensity work rate during different drills or for different players.

In football (soccer) in particular Metabolic Power variables have superseded the use for this variable as it integrates the energy cost of acceleration and deceleration along with running speed.

CALCULATIONSDistance in each speed zone is multiplied by a (configurable) weighting factor. The resultant values are then summed to provide the Speed Exertion of that period. As values are configurable in Team AMS/Analysis/Zones section, speed exertion can be configured in a number of ways depending on the goal of the analysis.

Default settings represent an exponential relationship where higher speed zones have significantly higher weightings.

DERIVATIVESSpeed Exertion Per MinuteIndicator of high intensity running work rate

GPSPORTS VARIABLES

ACCELERATIONS & DECELERATIONS

Acceleration and decelerations measure the change in speed of the athlete.

PRACTICAL APPLICATIONSThe acceleration and deceleration load in many team sports accounts for a significant amount of the metabolic and mechanical stress. Quantifying and managing acceleration and deceleration load is critical to managing the loadingstimulus.

Acceleration and deceleration counts can be manipulated in training by adjusting training time, drill sizes and drill numbers. An understanding of this and the ability to cycle the load is fundamental to implementing a varied trainingstimulus. Excessive overload of these parameters have been related to mechanical stress injuries of joints and musculature of the thigh and lower leg.

CALCULATIONS5 GPS data points are used to calculate acceleration or deceleration. A line of best fit is used to determine the gradient of the line and therefore the average change in speed. Accelerations and decelerations are reported in metres persecond squared (m/s2). Accelerations above, and decelerations below the configurable threshold are reported as an events. A count of these events is what is reported.

ACCURACY AND RELIABILITYThe GPSports acceleration method reports average acceleration over a 0.8s time period. This is more accurate and reliable than point to point GPS calculations due to inherit errors in GPS data. Inter unit reliability is in the order of a 5-10% difference between units. This error is largely due the slight variations in raw GPS data. This margin is still acceptable for practical interpretation of results.

DERIVATIVESAccelerations Per Minute or Decelerations Per Minute Total Accelerations & Decelerations Per MinuteIndicator of the rate of speed change events. Used to assess and compare individuals and drills.

Accelerations (or Decelerations) In ZonesFor example - Zone 3 Accelerations. This is a count of the number of high intensity accelerations.

Percentage of High Zone AccelerationsFor example - Zone 3 Accelerations as a Percentage of All Accelerations. This is an indicator of the percentage of high intensity accelerations. Commonly used as a acceleration quality marker.

GPSPORTS VARIABLES

SPRINTSSprints can be determined using a speed or acceleration threshold. Research has supported the use of both methods and terminology surrounding ‘sprint’ is mixed.

PRACTICAL APPLICATIONSUnderstanding the high intensity elements of sport and being able to quantify that at an individual level is of paramount importance to the analysis. The decision to use a speed or acceleration threshold is one of personal preference, and largely dependent on the sport, goal of the analysis and the other variables being used.

CALCULATIONSWhen using a Speed ThresholdThe analysis quantifies the number of efforts lasting a minimum of 1 second above the set threshold. The speed andtime thresholds are configurable and can be used to assess extended periods of high speed running.

When using an Acceleration ThresholdThe methodology and practical implications are the same as the Acceleration variable. Settings can be adjustedto elicit the same results.

DATA SOURCEGPS data is used in this analysis.

GPSPORTS VARIABLES

REPEAT SPRINTS EFFORTS (RSE)

Designed to assess the density of sprint efforts during a period of activity.

PRACTICAL APPLICATIONSThis is a key indicator of the ability of an athlete to repeat high intensity efforts.Make inferences regarding the demand of training and game, comparison of athletes, sessions and positional demands

CALCULATIONSThe recovery interval between sprints is determined from the end of one sprint to the beginning of the next. The Team AMS/Analysis/Sprint section allows the Repeat Sprint Effort - Recovery Interval to be determined. If the recoveryinterval between sprints is less than the RSE Interval threshold, the sprint will be reported as a repeat sprint.

More information on Repeat Sprint logic and settings can be found in Team AMS/Help/FAQ.

GPSPORTS VARIABLES

METABOLIC POWERMetabolic Load variables have increased in popularity in recent times. The analysis uses an energetics approach to quantify running intensity. The adaptation of the methodology to field sports has been led by Italian academics Di Prampero (2005) and Osgnach (2009) and has resulted in a strong following in European Football.

PRACTICAL APPLICATIONSThe analysis calculates the instantaneous energy cost based on an individual’s running speed, acceleration and deceleration. The integration of these commonly used GPS variables (i.e. speed and acceleration) provides a uniqueinsight to compare sessions, players, and drills.

KEY VARIABLESMetabolic Load (Relative)Energy cost per kilogram to complete the activity (kJ/kg)Practical Application – Relative load marker

Metabolic Load (Absolute)Total Energy cost to complete the activity (kJ)Practical Application – Absolute load marker

Average Metabolic Power Rate which energy is expended per second (W/kg)Practical Application - Indicator of average work intensity. Use this to compare drills, periods of match play or players

High Metabolic Load DistanceDistance covered at more than 20W/kg. 20W/kg equates to running at 5m/s and accelerating at 2m/s/sPractical Application – Indicator of the volume of high intensity work

Equivalent Metabolic DistanceDistance the player would have travelledbased on their energy expenditure if they moved at a constant speedPractical Application – Integrated volume marker

SOURCE AND CALCULATIONSGPSports runs this analysis using GPS data. The detailed methodology and rationale is explained by Osgnach (2009). This paper also discusses the limitations of this approach.

ACCURACY AND RELIABILITYWhile it is beyond our scope to determine the accuracy of these variables, testing has shown inter unit reliability to be in the order of 3-5% for the variables listed above.

GPSPORTS VARIABLES

IMPACTSACCELEROMETER VARIABLES

GPSports reports Impacts as a means of capturing the 3 dimensional accelerations an athlete is exposed to.

Low intensity impacts of 2-6G are commonly seen during running and walking. These impacts are primarily the vertical forces elicited at ground contact, but also include lateral and frontal plane movements related to the gait cycle. Several thousand low intensity impacts may be seen during a football match. Generally, a strong correlation between number of low intensity impacts and distance travelled is seen in running sports.

High intensity impacts commonly occur in sport. These impacts occur in a number of ways. Aggressive changes in direction, falling to ground, landing from jumping, collisions and tackles are all capable of eliciting high intensity impacts.

PRACTICAL APPLICATIONSThe best guide of how to interpret Impacts comes from McLellan et al. This paper indicates a strong relationship between number of high intensity impacts (>8G) and post-match plasma Creatine Kinase levels in elite Rugby league players.

Impact profiles are highly individual and dependent on the weight of the athlete, their movement mechanics and the fit of the unit. Due to these factors it is recommended Impacts are for individual, rather than group analysis.

DATA SOURCEGPSports devices contain a tri-axial accelerometer which registers acceleration in three planes (X,Y,Z). Impacts are the accelerations reported directly from the accelerometer and reported in ‘g’.

CALCULATIONSImpacts are reported as a count of impacts in zones. Zones are set in Team AMS/Analysis/Zones section.For example, 20 6g Impacts, reflects 20 peak accelerometer readings above 6g.

DERIVED VALUESImpacts Per MinuteIndicator of the rate of impact events.More information on Impacts can be found in Team AMS/Help/FAQ section.

NEW BODY LOADACCELEROMETER VARIABLES

New Body Load is calculated from the accelerometer data and is designed to reflect both the volume and intensity of accelerometer (acceleration) events.

New Body Load (NBL) replaces the original GPSports Body Load variable.

PRACTICAL APPLICATIONSDue to the nature of the calculation, NBL has shown a close correlation with distance run when the type of activity is controlled. NBL is heavily weighted by high impact activities such as intense accelerations, decelerations, changes indirection, high impact foot strikes, rapid changes in posture and collisions.Based on this, NBL is an integrated loading variable and is used as a training load marker (NBL) and work rate marker (NBL/min).

Due to the individual differences in results, some care needs to be taken not to use this variable for player comparisons.

DATA SOURCETri-axial accelerometer.

CALCULATIONSSee Team AMS/Help/FAQ documentation.

DERIVED VALUESNew Body Load Per MinuteArguably, the most useful variable from the NBL analysis. Apply this variable to drill split data to observe a relationship with work intensity.

More information on New Body Load can be found in Team AMS/Help/FAQ section.

COLLISIONSACCELEROMETER VARIABLES

Given the energy cost of collisions in sports like rugby union, rugby league and American football it is enlightening to be able to accurately report on these events. For many teams this has been a missing element with respect to quantifying player loading.

PRACTICAL APPLICATIONSObjective information about the occurrence of intensive collision events allows the exposure to be managed to optimise player health and performance.

KEY VARIABLECollisions CountNumber of collisions detected during the period.

CALCULATIONSGPSports uses integrated GPS and Accelerometer data to accurately detect and quantify collision events. Read more on Collisions in TEAM AMS/Help/FAQ section.

ACCURACY AND RELIABILITYInternal investigations have seen high levels of accuracy using data from numerous football codes. An independent validation project is currently being completed by The School of Exercise and Sports Science at The University of Sydney. This validation uses over 150 full game files and should be published early in 2014.

RECOMMENDED SETTINGS TO IDENTIFY COLLISIONSThe ideal threshold to identify collision events for most contact sports is using the GPSports Collision Threshold of 3g-4g depending on the type of device used.

Specifically:• SPI HPU devices (16g accelerometer) – Recommended Collision Threshold is 4g• SPI ProX devices (8g accelerometer) – Recommended Collision Threshold is 3g

More information on Collision Detection can be found in Team AMS/Help/FAQ section.

RUNNING SYMMETRYACCELEROMETER VARIABLES

Gaining a deeper insight into an athlete´s running mechanics and the changes in their mechanics due to injury, fatigue, or other limitations, provides critical information to maximise performance and manage risk.

PRACTICAL APPLICATIONSThe initial goal is to establish a normal range for each athlete and identify changes at an individual level. Further specific applications include:

Rehabilitation – See changes over time as the athlete improves during the process of rehabilitationReturn to Play – Use Running Symmetry as an objective return to play markerAthlete Screening – Use Running Symmetry on a weekly basis to identify changes in running mechanics

KEY VARIABLESImbalance - % Difference between left and right foot strikesFoot Strike - Number of Foot Strikes in the analysisSeries - Number of series of foot strikes that are used in the analysisStandard Deviation - The Standard Deviation of scores from each Series

SOURCEGPSports uses integrated GPS and Accelerometer data to complete this analysis. The software identifies, quantifies and compares the forces at ground contact (foot strike) on the right and left sides during running.

CALCULATIONSThe percentage difference between the left and right foot strike is reported to the user as ‘Imbalance’. For example, a score of ‘zero’ represents a symmetrical running stride. That being, a series of foot strikes where the left is the same asthe right side. A ‘5% Right’ score reflects an asymmetrical stride, specifically a 5% greater load on the right side, compared with the left.

To complete the analysis GPSports identifies a specified number of foot strikes in sequence combined with settings to control for change in direction and speed as these events are known to not be symmetrical.

ACCURACY AND RELIABILITYSee the results of the validation trials in Team AMS/Help/FAQ section.

RECOMMENDED SETTINGS TO IDENTIFY COLLISIONSMinimum Speed Threshold – 10-12km/hMinimum Number of Foot strikes – 10
