To determine the daily energy requirements of soccer players, we measured total energy expenditure(TEE) in nine Korea professional Football League players(mean±SD; age 29±4years, height 180±7cm, body mass 75.7±10.3kg) during 7 days of a competitive season using the doubly labeled water(DLW) method. Energy intake(EI) was simultaneously estimated from 7 days of dietary records. Mean TEE and EI were 16.8±2.4MJ/day(4013±583kcal/day) and 16.4±1.6MJ/day(3941±382 kcal/day), respectively. Although there was no significant difference between total energy expenditure and energy intake, there was a strong relationship between the two (r= 0.747, P< 0.05). A physical activity level(PAL=TEE/estimated basal metabolic rate) was 2.22±0.28. We discussed the energy requirements of soccer players during a competitive season based on PAL of both Korea and Japan professional Football League players.
