Articles : Total Energy Expenditure of Professional Soccer Players Measured by the Doubly Labeled Water Method
Abstract
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 compertitive sesson using the doubly labeled water (DLW) method. Energy intake (El) was simultaneously estimated from 7 days of dietary record. Mean TEE and El were 16.8±2.4 MJ/day (4013±383 kcal/day) and 16.4±1.6 Mj/day (394l±382 kcal/day), repectively. Although there was no significant difference between total energy expenditure and energy intake, there wat a strong relationship between the two (r= 0.747. p<0.05). A physical activity level (PAI. = TEE/estimated basal metabolic rate) was 2.22±0.28. We discussed the energy requirements ofsoccer players during a competitive season based on PAL of both Korea and professional Football League Players.
Key Words: professional soccer player, total energy expenditure, doubly labeled water method, energy intake, physical activity label
