Description
Summary: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.
