ABSTRACT
The purpose of this study was to observe the physiological changes in body composition
and fitness assessments in US Army Officers after 5 months of non-mandated exercise. Twenty-
two captains stationed at Fort Benning, Georgia volunteered to participate (age; 26.9£1.2 years,
height; 1.76+0.6m, and weight; 83.1+11.1kg). Eleven participants remained in active units with
mandated training (MT) while 11 participants were in positions where training was not mandated
(NMT). Anthropometrics, body composition, cardiorespiratory fitness, anaerobic power, and
muscular strength were measured in both groups before and after the intervention period (1812
weeks). At pre-intervention, MT and NMT were not different in body composition,
cardiorespiratory fitness, anaerobic power, or muscular strength (P>0.05). Post-intervention,

there were no significant time x group interactions observed in anthropometrics, body
composition, cardiorespiratory fitness, anaerobic power, and muscular strength between groups
(P>0.05). However, a main effect of groups was attained in body fat, VOzpeak, and peak power
(P<0.05) and main effect of time was observed across all participants in VOzpeak and push-up
performance (P<0.05). Plausible explanations can be due to the observed rank and limitations of
the Army Physical Readiness Training (APRT). Further research is warranted investigating the
effect of mandated exercise in officer ranks and physical performance.
KEY WORDS: exercise, military, fitness
ACKNOWLEDGEMENTS
I would like to acknowledge and extend my sincerest gratitude to the Columbus State
University Exercise Science professors and fellow graduate students. This study would not have
been able to complete this study without the consistent support and encouragement from all. I
would also like to give a special thanks to my thesis chair, Dr. Kate Early. As my teacher and
mentor, she has taught not only about scientific research but life in general. Her countless hours
of guidance and mentorship will follow me to all future endeavors.
