Comparison of energy requirement estimation using activity record or accelerometer with doubly labeled water method in collegiate male sprinters.

Background & Aims: Track and field sprinters must obtain an optimal body composition to improve sprint performance. To successfully change body composition, it is important to evaluate the estimated energy requirements (EER) and fluctuations in total energy expenditure (TEE). However, methods to accurately evaluate the EER and TEE in sprinters have not been fully investigated.
