This study aimed to recommend the energy and protein requirements on general training and match days for Japanese male senior high school soccer players. Seven players were surveyed and measured during two consecutive days of training (training group). Nine players were surveyed and measured during two consecutive days of expeditions (match group). The recommended energy intake (EI) was estimated using total energy expenditure (TEE) measured by Misfit Shine, a triaxial acceleration sensor-mounted activity meter. The recommended protein intake was estimated using measured values obtained by the nitrogen balance (NBAL) method. Results suggested that EI should be 48–52 kcal/kg/day on training days and 49–54 kcal/kg/day on match days. Results also suggested that protein intake should be 0.8–1.5 g/kg/day on training days and 1.4–2.4 g/kg/day on match days. Moreover, we believe that the recommended energy and protein intake for Japanese male senior high school soccer players on match days should be higher than on training days.
