Adequate energy intake in adolescent athletes is considered important. Total energy expenditure (TEE) can be calculated from resting energy expenditure (REE) and physical activity level (PAL). However, validated PAL recommendations are available for adult athletes only. Purpose was to comprise physical activity data in adolescent athletes and to establish PAL recommendations for this population. In 64 competitive athletes (15.3 ± 1.5 yr, 20.5 ± 2.0 kg/m2) and 14 controls (15.1 ± 1.1 yr, 21 ± 2.1 kg/m2) TEE was calculated using 7-day activity protocols validated against doubly-labeled water. REE was estimated by Schofield-HW equation, and PAL was calculated as TEE:REE. Observed PAL in adolescent athletes (1.90 ± 0.35) did not differ compared with controls (1.84 ± 0.32, p = .582) and was lower than recommended for adult athletes by the WHO. In conclusion, applicability of PAL values recommended for adult athletes to estimate energy requirements in adolescent athletes must be questioned. Instead, a PAL range of 1.75-2.05 is suggested.
青少年运动员充足的能量摄入被认为很重要。总能量消耗（TEE）可根据静息能量消耗（REE）和体力活动水平（PAL）来计算。然而，经过验证的PAL建议仅适用于成年运动员。目的是汇总青少年运动员的体力活动数据，并为该人群建立PAL建议。在64名竞技运动员（15.3±1.5岁，20.5±2.0kg/m²）和14名对照组（15.1±1.1岁，21±2.1kg/m²）中，使用经双标水验证的7天活动方案计算TEE。通过Schofield-HW方程估算REE，并将PAL计算为TEE:REE。青少年运动员观察到的PAL（1.90±0.35）与对照组（1.84±0.32，p = 0.582）相比无差异，且低于世界卫生组织为成年运动员推荐的值。总之，为成年运动员推荐的PAL值用于估算青少年运动员能量需求的适用性值得质疑。相反，建议PAL范围为1.75 - 2.05。
