The effects of acute and 2 hour post-physical activity on the estimation of body fat made by the Bod Pod

The Bod Pod has been found to be both reliable and valid against several criterion methods such as hydrostatic weighing, and dual energy x-ray absorptiometry, and under different conditions, such as clothing level, dehydrated states, and body temperature changes. However, questions still remain regarding the effects of an acute bout of exercise on the Bod Pod. Therefore, the purpose of this study was to determine the effects of an acute bout of exercise on the estimations made by the Bod Pod. Participants (15 males and 22 females) ranged in age from 18-27 years and were currently exercising. Height and weight were measured prior to entering the Bod Pod. Baseline Bod Pod measures were completed followed by a 30 minute cycling trial at 75% of heart rate max. Bod Pod measures were taken immediately following exercise and 2-hr post-exercise. Statistical differences between males and females were found at baseline between height (p
