Abstract:

A sensitive, reliable, field expedient physical performance test would be a valuable tool for monitoring training progress and experimental interventions. We hypothesized that repetitive unloaded jump tests could be used to monitor physical performance status. Twenty-nine U.S. Marines attending Infantry Officer Course performed 1, 5 and 30 repetition unloaded counter-movement squat jumps UJ to assess the efficacy of UJ for monitoring physical performance pre and post and 8-d field exercise composed of near continuous work, sleep disruption and underfeeding SUSOPS. Peak jump height and power were highest using 1UJ p0.05 and fell 4.9 and 8.9, respectively after SUSOPS p0.05. Jump power fell progressively over 30 UJ 19-20, but SUSOPS had no affect on rate of fatigue. 5UJ offered no advantages over 1UJ and was inadequate to examine changes in muscle fatiguability. In conclusion, 1UJ was a sensitive, easy to implement, physical performance test for monitoring the impact of military training on warfighter readiness.
