Physical Fitness and Physical Performance during Continuous Field Artillery Operations
Abstract
The purposes of this study were to 1) determine the effects of a continuous field artillery scenario on physical fitness capacity and performance, 2) relate physical capacity to task performance during the scenario, and 3) estimate the physical intensity of the scenario by continuous heart rate monitoring. Twenty-four artillerymen comprising three, 8-man guncrews participated in an 8-day, combat-simulated operation. Body composition and measures of fitness (isokinetic strength of the arms and legs, isometric handgrip strength, dynamic lifting, and upper body anaerobic power) were determined before and immediately following the scenario. Physical performance was assessed by daily ratings from senior noncommissioned officers experienced in artillery operations. The intensity of physical activity and amount of sleep were estimated from continuously recorded heart rate using Oxford Medilog electrocardiographic tape recorders worn by the soldiers. The results suggest that 1) soldiers who are allowed 5 hrs sleep per day and who are required to perform at capacity or evidence of physical fatigue for up to 8 days of continuous operations, 2) the physical fitness of artillerymen was comparable to other Army populations of similar age and proved adequate to meet the physical demands of this scenario, and 3) soldiers undergoing realistic, continuous field artillery operations are able to obtain adequate sleep and spend only short periods at high levels of physical activity.
