ABSTRACT
Today, athletes and weight lifters are going to extreme measures to gain an advantage in
performance. As a result, pre-workout supplements have become very popular. Ammonia
inhalants have been reported to produce a similar effect to pre-workout supplements
because they are suggested to increase consciousness and physical strength. Still the
effect of ammonia inhalants on strength performance is unknown. The purpose of this
study was to examine the relationship between two measures of strength performance
with ammonia inhalants. The participants in this study were 25 male weight lifters.
Participants were tested in the back squat and bench press at 85 percent of their
calculated 1 repetition max (1RM), at two different sessions. The participants inhaled
either the ammonia inhalant or the placebo prior to performing as many repetitions as
possible in the back squat and bench press at 85 percent of their 1RM. A paired samples
dependent T-Test along with an ANOVA was used to analyze any differences between
the placebo and the ammonia inhalant. The results revealed that there were no significant
differences in strength testing between the ammonia inhalant, placebo, or no substance at
all. The results in this study suggest that ammonia inhalants do not increase strength in
male weight lifters.

CHAPTER 1: INTRODUCTION
Pre-Workout supplements are very popular in today’s fitness realm. Many
athletes, power lifters, bodybuilders, and recreational lifters use pre-workout supplements
prior to resistance training to increase training motivation and muscular strength.
Previous studies have shown that significant benefits in muscular strength and power can
be acquired from using pre-workout supplements within an hour prior to the resistance
training session (6,17). Today ammonia inhalants (AIs), also known as smelling salts,
like other pre-workout supplements are used to enhance performance in competition and
also in workouts prior to heavy resistance training sets. AI use is widespread among
athletes and power lifters all over the world to gain an edge (10). AIs are most commonly
used to increase muscular strength for a short period of time (8).
Usually AIs are in the form of capsules and composed of ammonium carbonate
combined with scents or perfumes. According to McCrory (10), AIs are categorized as a
respiratory stimulant. They were originally utilized to prevent and treat fainting,
dizziness, and lightheadedness. We now know that AIs do not cure the underlying
problem of injuries but only provide temporary relief (18). When AIs are sniffed or
inhaled, the nose, lungs, and mucus membranes rapidly become irritated causing
involuntary inhalation. This involuntary inhalation is reported to accelerate respiration
and stimulate a higher degree of consciousness (10). A “higher degree of consciousness”
may be responsible for increasing primary attentional focus which allows the weight lifter
to block out unnecessary distractions and primarily focus on the task of executing the
exercise; a psychological trait that many expert athletes utilize to perform successfully
under pressure (13).
2
AIs are approved in the United States today through the Food and Drug
Administration for the treatment of fainting, and are offered over the counter. It should be
noted that ammonia is toxic in large amounts, and should only be administered in small
doses and given to users without any pre-existing medical conditions (18). Complications
caused by AIs in athletes have been reported but are rare (8). These complications
include lung irritation/damage, loss of consciousness, and anaphylaxis. People with
respiratory issues like asthma should avoid using AIs because the lungs will become
irritated. It is also recommended that AIs not be used to aid head and neck injuries
because they can cause a sudden unexpected reflex. The movement of a sudden reflex
can cause the head and neck to quickly contract which can increase the severity of the
injury (18).
Athletes commonly use AIs immediately before or during competition, such as
prior to attempting a 1-repitition maximum (1RM) attempt in the bench press, back squat,
deadlift, or power clean. AIs are also used before the opening kickoff of a football game,
between rounds of a boxing match, or in locker rooms during breaks or intermissions of
games (18).
Although AIs have been around and used for many years little is known about
their effects on athletic performance. The lack of research provides no formal proof that
AIs provide athletes any ergogenic benefit. There is essentially no research that has
examined the effectiveness of AIs in athletic performance (18).

CHAPTER 2: REVIEW OF LITERATURE
In the past, research has been conducted examining many different supplements
and ergogenic aids used by athletes to increase performance. To date, most studies have
found an actual benefit in use of these supplements and ergogenic aids; however, other
studies did reveal a significant performance enhancement. Therefore definitive
conclusions on the benefits of several supplements and ergogenic aids are very
controversial or unknown. A review of previous research can assist in understanding the
effectiveness of ergogenic aids and dietary supplements on multiple levels of exercise
performance.
Caffeine, like AIs, is used prior to exercise to increase performance. Wolff et al.
(19) measured the effect of caffeine on 17 collegiate football players who performed tests
used at the NFL combine (40 yard dash, 20 yard shuttle, and 225 lb. bench press). The
experimental design required the participants to appear for 2 visits separated by 1 week.
Participants ingested either a placebo or a caffeinated beverage along with a light meal 1
hour prior to the NFL combine testing. Data was analyzed by a paired T-test, Wilcoxon
signed rank test, and a repeated measures analysis of variance. The results revealed that
caffeine did not significantly improve performance in these tests compared to the placebo
given to the athletes.
Athletes have also used a dietary supplement called Carnitine, to increase
muscular strength similarly to what has been reported of AIs. Athletes have claimed that
after ingesting Carnitine their muscular endurance and performance in high intensity
exercise increases. Although there have been anecdotal reports of performance
4
enhancement while taking Carnitine, multiple studies have shown no significant increase
in endurance or high intensity exercise (5,7).
L-arginine is a dietary supplement that has been marketed to promote increased
blood flow to the skeletal muscles and brain. AIs have been reported to give a “higher
degree of consciousness” which could also be a result of increased blood flow to the
skeletal muscles and brain. It has been suggested that L-arginine increases vasodilation
(blood flow) to muscles and in turn enhances muscular strength during exercise. Alvares
et al. (2) conducted a study with 15 healthy males who had at least 3 months previous
resistance training experience. The participants were randomly separated into either a
placebo group or a group supplemented with L-arginine. Eighty minutes prior to
engaging in exercise testing the participants ingested either the placebo or the L-arginine.
The exercise protocol in this study consisted of the participants performing elbow flexion
and extension exercises. Approximately 1 week after the initial testing session the
participants were required to return and perform a second testing session. In the second
session the participant ingested the supplement that they did not receive the prior week.
The results of this study revealed that after ingesting L-arginine, vasodilation did
significantly improve compared to the placebo, but muscular strength during the exercise
protocol did not significantly improve.
High energy pre-workout supplements have also become a trend in the fitness
realm. A large portion of the population invests in high energy supplements in hope to
increase energy expenditure and to also burn fat. High energy supplements are thought to
give a “boost” during a training session similar to what AIs are reported to do. Hoffman
et al. (9) explored the effects of a high energy pre-workout supplement on oxygen
consumption, heart rate, blood pressure, and fat utilization on 10 female participants.
5
Participants in this study attended 2 sessions separated by an average of 8 days in which
they received a placebo or the high energy pre-workout supplement. Immediately after
ingestion the researchers measured the participant’s oxygen consumption and heart rate
every 5 minutes for the first 30 minutes, then every 10 minutes until 180 minutes was
reached. Blood pressure was measured at 15 and 30 minutes post ingestion, and then
every 30 minutes until 180 minutes was completed. A dependent t-test was used to
analyze the comparisons between the high energy workout supplement and the placebo.
The results revealed that there was no difference in heart rate or blood pressure between
the two treatments. Although energy expenditure did not increase, the high energy pre-
workout supplement did show a significantly higher use of fat as an energy substrate than
the placebo.
While many supplements and ergogenic aids have been demonstrated to illicit no
significant benefit during exercise, there are cases where supplements and ergogenic aids
have enhanced performance. Recently a study by Gonzalez et al. (6) examined the
effects of a new energy drink “Amino Impact” on exercise training volume and power
performance. Amino Impact contains ingredients like caffeine, creatine, and amino acids
to increase power and focus during a workout. This study took 8 college age, resistance
trained men who underwent 3 testing sessions. In the first testing session each
participant’s 1RM was assessed in either the bench press or back squat exercise. In the
second testing session the participant ingested either “Amino Impact” or the placebo 10
minutes prior to performing no more the 10 repetitions at 80% of their 1 repetition max.
Approximately 1 week after the second session the participant attended the third session.
In the third session the participant ingested the other supplement, either the placebo or
Amino Impact. Then waited 10 minutes and once again performed no more than 10
6
repetitions at 80% of their 1 repetition max. The number of repetitions from each session
was documented along with questionnaires that measured feelings of energy, focus, and
fatigue using visual analog scales. A Tendo Power Output Unit was also utilized to
measure power on the bench press and back squat. The results showed that participants
completed significantly more repetitions and were significantly more powerful after
ingesting the Amino Impact supplement compared to the placebo.
Alghannam (1) examined the difference between a carbohydrate beverage versus
a carbohydrate beverage that contained protein, and how it affected running capacity in
football players. This study used a sample of 6 male amateur football players. The
experimental design consisted of 4 total visits. During the first visit the participants
completed preliminary measurements. In the second, third, and fourth visits the
participants ingested the placebo, carbohydrate, or carbohydrate with protein beverage 15
minutes prior to engaging in football specific running. The results in this study indicated
that when participants ingested the carbohydrate with protein beverage, they were able to
run longer before they became fatigued.
Creatine supplementation has repeatedly been proven to be effective in elevating
strength performance. A recent study looked at the effects of Creatine supplementation
on the local muscular endurance of in-season rugby players (4). Over 8 weeks of a rugby
season, 9 players ingested a Creatine supplement and 9 ingested a placebo. Muscular
endurance was measured by instructing the participants to complete as many repetitions
as possible at 75% of their 1 RM in the bench press and leg press exercises. The first test
was administered at the start of the 8 weeks and the second test was administered at the
end of the 8 weeks. Results in this study revealed that when total repetitions completed in
7
the leg press and bench press were combined, the participants who ingested Creatine
completed more repetitions.
b-Hydroxyb-Methylbutyric acid (HMB) is a dietary supplement that is used by
athletes today to gain a competitive advantage by potentially increasing fat free mass and
gaining muscular strength. Portal et al. (14) examined the effects of HMB on body
composition and fitness in male and female adolescent volleyball players. Twenty nine
participants in this study were randomly assigned to a placebo or HMB group. Placebo or
HMB pills were given to the participants for 7 weeks, every morning at practice. At the
beginning of the 7 weeks participants completed a baseline assessment of body
composition and muscular strength. At the conclusion of the 7 weeks participants
completed the same assessments. Results revealed that HMB supplementation was
associated with an increase in muscle mass and muscular strength when compared to the
placebo.
This raises the research question do AIs fall into the list of supplements and
ergogenic aids that do not increase performance? Or do AIs belong with the list of
ergogenic aids and dietary supplements that do increase performance? If AIs demonstrate
that they cause no increase in strength performance then why are they used? It is hoped
that through this study information will be provided as to the effectiveness of AIs in the
of strength performance. This study hypothesizes that the use of AIs will increase
strength performance.

CHAPTER 3: METHODS
Experimental Design
This study used a sample of 25 male weight lifters (age: 21.5±2.2 years, height:
71.3±1.8 in., weight: 206±31.4 lbs., Resistance Training Experience: 7.3±2.6 years). The
term “weight lifter” is defined by participants that reported at least 3 years of resistance
training experience and who can back squat 1.5 times their body weight and bench press
1.0 times their body weight (3,15). People who did not meet these criteria were not
allowed to participate in the study. As a safety precaution each participant in the study
completed a medical history form to assist in screening out individuals that have any
cardio, respiratory, or muscular conditions (Appendix A). This study is a double blind,
repeated measures study in which after establishing a calculated 1RM, sub maximal
attempts of the back squat and bench press are completed by each participant twice (at
85% of their calculated 1RM). In random order, one attempt was with the AI, and one
was with Vicks Vapor Rub (VVR); which is placebo. VVR was chosen as a placebo in
this study because of its strong menthol scent that is comparable to an AI. The back
squat and bench press exercises were selected in this study because they are measures of
upper and lower body strength, are highly utilized in training, and correlate to athletic
performance (11). Approval to utilize these substances along with human subjects was
granted by the Missouri State University IRB (February 12, 2013; approval #13-0316).
Procedures
The first session the participants attended was to estimate their 1RM on the back
squat and the bench press. Participants were instructed not to engage in any demanding
9
physical activity at least 48 hours prior to any of the testing sessions so that the central
nervous system and muscular system would be fully recovered. Allowing 48 hours
between sessions is acceptable due to the highly trained state of this population and their
ability to recover faster than a population that is not accustomed to resistance training
(12). Participants were also instructed to eat a meal at least 3 hours prior to each testing
session. Upon arrival the participants completed a questionnaire inquiring resistance
training experience /history of medical health (Appendix A). During this time they also
signed an informed consent document (Appendix B). Next the participants were weighed
without shoes on a scale in pounds. Then they began a general warm up on an Aerodyne
Ergometer for 5 minutes. It has been shown that muscles warmed up prior to resistance
training perform better than muscles that do not (16).
Following the warm up on the Aerodyne Ergometer participants began their back
squat warm up. Participants performed the back squat test prior to the bench press test in
this study because the squat exercise involves larger muscle groups which should be
trained prior to smaller muscle groups (3). A standard squat rack with a 45 pound barbell
was used for the all of the back squat testing. Participants were already familiar with
proper back squat technique from previous training experience, but proper technique was
re-emphasized prior to and during all lifting. Technique was derived from the National
Strength and Conditioning Association, which consists of the feet being parallel to each
other and also shoulder width apart, with the barbell resting on the shoulders. For the
repetition to be deemed successful the participant must to descend with the hips and
knees until the thighs were parallel to the floor and then stand up from that squatting
position (3). Each participant started his first squat warm up set with 135 pounds. Each
squat warm up set consisted of 1-6 repetitions. Then the participant increased the
10
resistance 20-90 pounds each set until he reached a weight he could perform only 2 to 5
repetitions with maximal exertion and proper technique . The sets performed to maximal
exertion are known as the Repetition Max (RM). The Baechle formula was utilized to
calculate a 1 Repetition Max (1RM) by using the number of squat or bench repetitions
performed. This 1RM represents the estimated amount of weight that can be performed
once by the participant. After a1RM was found on the back squat, the participant was
given a five minute break before starting the bench press warm up. The bench press
technique was also derived from the National Strength and Conditioning Association.
The technique consisted of the head, back, butt, and legs contacting the bench or floor at
all times (3). The participant was instructed and demonstrated by the researcher to lower
the barbell to touch the chest and then raise the barbell by fully extending the elbows to a
locked out position. The repetition was not deemed successful if the participant failed to
utilize the demonstrated technique. Next the participant completed at least 3 warm up sets
before attempting the RM set. After the RM has been attained in the bench press the
Baechle formula was utilized to calculate a 1RM.
Within 2 to 5 days (at least 48 hrs.) after the initial testing, the second testing
session took place. In second testing session participants started with a warm up on the
Aerodyne Ergometer for 5 minutes, and then start their squat warm up. In this session the
participant completed at least 4 squat warm up sets with approximately 1 minute between
sets. During these warm up sets a marked coin was flipped to randomly assign which
substance the participant would inhale first. Next participants would prepare to perform
RM set with 85% of their predicted 1RM. Three seconds before initiating the RM set the
participant sniffed either an AI or VVR (placebo) until they noticed a scent in their
11
nostrils. The content of the substance sniffed was unknown to the participant and also to
the researcher who administered it.
After the RM set was completed the participant got a 5 minute break and then
began the bench press warm up. After 4 sets of bench press warm up the participant also
completed their RM set at 85%. Three seconds prior to the RM set the participant will
once again sniff either the AI or VVR (placebo). The participant always inhaled the same
substance on bench as they did on squat in each session. The third testing session was
also 2 to 5 days after the second session. The procedures of this session were the same as
the second testing session except the participant inhaled the substance that they did not
sniff during the second session.
Statistics
The number of repetitions completed by each participant during the RM sets in
each session was documented. A Paired Samples T-test was utilized to measure any
significant differences in the number of repetitions completed after inhaling the AI or the
VVR within the participants. Using the weight and repetitions completed in the second
two sessions a 1RM was calculated. A Paired Samples T-test was also used to examine
any possible significant differences in the calculated 1RM’s of the second and third
sessions. Lastly an Analysis of Variance (ANOVA) was used to measure any significant
differences in the calculated 1RM’s of all three sessions.
12
CHAPTER 4: RESULTS
The results were based on 25 male participants who completed all 3 testing
sessions. Three participants did not finish the study due to scheduling issues. Participants
who completed the study reported no physical injuries due to the testing protocol. The
subject characteristics are located in table 1. After running the Paired Samples T-test it
was apparent that there was no significant difference between the amount of repetitions
performed in the back squat or the bench press after inhaling the AI compared to the
VVR (Back Squat; p=0.403, Bench Press; p=0.422). There was also no significant
differences between the calculated 1RM’s of the AI testing sessions compared to the
VVR testing sessions (Back Squat; p=0.534, Bench Press; p=0.344). The results of the
ANOVA also revealed that there were no significant differences in the 1RM’s of the back
squat and bench press exercises compared to the initial testing session when no
substances were inhaled. Mean and the standard deviation statistics of the back squat and
bench press are located in table 2 and table 3.

DISCUSSION
Data Limitations
The results in this study revealed that there were no significant differences
between any of the testing sessions. One limitation which may have affected the results in
this study includes how each participant spent his time between testing sessions.
Although participants were instructed to remain physically inactive at least 48 hours prior
to all testing sessions, it can only be assumed that these instructions were followed by
each participant. Any kind of strenuous physical activity within 48 hours of testing
sessions could have drastically affected the participant’s performance on the back squat
and bench press. Another limitation in this study was the number of participants. Results
may have been more significant if the number of participants in the study was higher.
The amount of Ammonia that was inhaled by each participant can also not be
accounted for. Although each participant inhaled the ammonia from the same size
capsule, the amount of inhalation by each participant may have been much different. If
some participants inhaled more ammonia than others the results may have been affected.
Another issue that will have to be answered in future research is how the AI
would affect back squat and bench press performance at a higher percentage of a 1RM
(higher than 85% of 1RM). It is understood that anecdotal reports suggest AIs are used
for short anaerobic bursts of strength. It may be possible that the effect of AIs on strength
performance only last a few seconds; enough for 1 to 3 repetitions but wear off for sets
that require more than 3 repetitions. Further research must be done to examine the effect
of AI’s on RM sets > 85% and repetitions ≤ 3 compared to RM sets ≤ 85% and that
involve >3 repetitions.
15
The results in the study are very similar to many previous experiments testing
ergogenic aids. For example, results in a study examining the effects of a dietary
supplement called Carnitine on exercise performance are very similar to the results
revealed in this study because they both did not increase performance (5). Caffeine has
also been compared to a placebo to increase performance in multiple studies. A previous
study that looked caffeine’s effects on athletes while performing NFL drills showed that
performance was not significantly increased compared to the placebo, much like the
results in this study (19). Other studies on ergogenic aids have enhanced performance,
including studies testing the protein supplement Amino Impact and also dietary
supplement HMB (14). Our results clearly demonstrate that this experiment falls into the
category of experiments that did not significantly affect exercise performance.
Practical Applications
The results of this study have revealed that there were no significant differences
in the AI testing sessions compared to the VVR sessions in the back squat and bench
press. Practically speaking, from the results of this study the use of AIs should vary from
person to person. If a weight lifter has no pre-existing medical conditions and feels that
AIs do improve their performance then they should feel free to use them in low doses.
For example if someone were performing a 1RM test on the back squat and wanted to use
an AI prior to their testing set, then that person should feel free to do so. On the other
hand, AIs should not be prescribed universally by trainers and strength coaches to every
client or athlete increase performance. This is because through the results of this study
the effect of AIs on back squat and bench press performance were insignificant. Instead
16
AIs should be administered on a case by case basis, depending on the person’s health
(especially respiratory health) and personal preference.
Summary
Although more research is needed on the effects of AIs relating to exercise
performance, our data suggests that there is no significant link between the two. More
research with a larger sample size may illicit different results. Also testing the
participants at a higher percentage of their 1RM or slightly increasing the dose of
Ammonia could also bring about different results as well. We suggest that AIs be
administered on a case to case basis, depending on the person’s health and personal
preference.

E-mail: [email protected] Email: [email protected]
You will need to sign this form giving us your permission to be involved in the project.
Taking part in this project is entirely your choice. If you decide to take part but later
change your mind, you may stop at any time. If you decide to stop, you do not have to
give a reason and there will be no negative consequences for ending your participation.
Purpose
The purpose of this study is to determine if ammonia inhalants affect muscular strength &
power.
Description of Procedures
1. The test you have selected to perform is designed to evaluate your muscular
strength and power after using ammonia inhalants (smelling salts) or a placebo
(Vicks Vapor Rub). Your eligibility to participate will be determined based on
guidelines established by the American College of Sports Medicine and the
answers provided by you after completing a medical history questionnaire and
training history questionnaire. If you are eligible and you chose to participate in
the study you will have your weight and strength measured.
a. The strength exercise testing will consist of a brief warm-up, following which you
will attempt an exercise test to determine how much weight you can lift ONE
time, this is known as a 1-repetition max (1RM). On subsequent days you will
then warm-up and then briefly (~1sec) inhale an ammonia inhalant (smelling) or
22
placebo and then lift 85% of your 1RM as many times as you can. Once you
complete the exercise you will perform a light cool-down and stretching. On
subsequent days you will warm-up then briefly (~1sec) inhale an ammonia
inhalant (smelling) or placebo (Vicks Vapor Rub) and then lift 85% of your 1RM
as many times as you can.
b. You will need to complete one additional training session using the same routine
(warm-up, inhale the substance and exercise cool-down) with the difference being
the type of smelling substance you inhale. The different types of smelling
substances are ammonia inhalant (smelling salt) or placebo (Vicks VapoRub).
The smelling substance you inhale will be randomly chosen.
2. The primary investigators for this study are Dr. Scott Richmond, PhD and Adam
Potts, CSCS; they will be responsible for collecting the information for this study.
3. All anthropometric data (weight) and exercise testing data will be collected in a
limited access exercise/testing space in McDonald arena and under direct
supervision of Scott Richmond.
4. Your total time commitment for participation will be approximately ONE to ONE
AND A HALF (1.0-1.5) hours over TWO to 5 (2-5) days (0.5hrs/day).
What are the Risks?
The possibility exists of certain physical changes occurring during exercise testing. As
with any exercise session, there is the remote chance of a serious cardiovascular event,
such as a heart attack or death. Other possible risks include, but are not limited to, those
normally associated with typical exercise: fatigue, shortness of breath, lightheadedness,
sweating and post-exercise muscle soreness. The Ammonia Inhalant will cause a short
irritation of the respiratory system during inhalation that will last seconds. The risk will
be minimized in a number of ways. You will be apparently healthy, with no self-reported
contraindications for strenuous exercise. The Ammonia Inhalant will be limited to two
inhales. You will be continuously monitored and trained individuals will be present
during all testing. Also please notify the researcher if you have pre-existing respiratory
conditions like asthma etc. In the event of an emergency, medical assistance will be
obtained for you. The cost of the care will be your responsibility. Financial assistance
will not be available from the project investigators or Missouri State University. This
investigation and the trials, which are a part of it, are offered on a voluntary basis. If you
choose not to participate or to withdraw at any time, the decision will not affect your
present or future relationship with Missouri State University or the investigators.
What are the Benefits?
The benefits involved with participation in this study can include but are not limited to
the determination of your body weight; the assessment of muscular strength, which can
be utilized to adjust current training routines, and contribution to the scientific body of
knowledge. Information in this study will be used to further the research that is developed
to assist in training athletes.
How will my privacy be protected?
23
Any information obtained in connection with this study will remain confidential. Only
data averaged for several subjects will be disclosed in scientific publications. Your
decision whether or not participate will not prejudice you future relationship with the
Missouri State University or the Department of Kinesiology at Missouri State University.
If you decide to participate, you are free to withdraw your consent and discontinue
participation at any time without penalty. If you decide later to withdraw from the study
you may also withdraw any information which has been collected about you.
