To determine the daily energy requirement of an elite female judo athlete before and after competition, total energy expenditure (TEE) was measured by the doubly labeled water technique over a 7-d period, for a-52kg female Japanese national team judo athlete [23 years,158cm]. Energy intake (EI) was also measured using a self-reported 7-d or 3-d weighed dietary record. TEE was 3004kcal/day and 2594kcal/day, and El was 2275kcal/day and 3100kcal/day in before and after competition, respretively. From energy balance (EB) and changes in body weight, adjusted-El (A-EI) was estimated during the preparation for competitionperiod. One benefit of A-EI is that it enables judo athletes successfully manipulate their ET and make cut-off weight for competitions, without compromising health or performance.
