Background:The *** Force physical fitness assessment(PFA)is used to determine the overall fitness of their *** is currently unknown to what extent the PFA scores of Reserve Officers’Training Corps(ROTC)cadets are affected by mandatory physical *** purpose of this investigation was to longitudinally examine the PFAs of ROTC cadets over a four-year period,evaluate the results across class ranks,and evaluate the sensitivity of the classification of the ***:Air Force ROTC cadets performed the PFAs(abdominal circumference,1-min pushups,1-min sit-ups,and a 1.5-mile run)in both the spring(n=26)and fall(n=22)*** were compiled over a four-year period(Spring 2014–Fall 2017)and were performed in accordance with Air Force Instruction 36–2905.A oneway repeated measures ANOVA was performed separately for the fall and spring groups for each dependent variable across the 4 ***,a one-way between groups ANOVA was performed for each dependent variable during the time point(fall 2015;n=46)with the most recorded cadets for each class ***:Longitudinal assessments revealed a main effect of time(P=0.010)on abdominal circumference;cadets had a smaller abdominal circumference in their freshman year than in their senior year.A main effect of time(P=0.006)was also observed on sit-up quantity;cadets performed more sit-ups in their junior year than in their freshman *** between class ranks during the same year(between-subjects ANOVA)revealed a main effect of class rank on sit-up quantity(P=0.003);the freshmen completed fewer repetitions than the sophomores(P=0.018)and the juniors did(P=0.001).Conclusions:The results indicated that only the sit-up component showed differences between class *** findings suggest that the Air Force PFA may not be sensitive enough to detect changes in physical fitness or distinguish between class ranks regarding physical performance,even after years of *** limitation may b
