Abstract

Objective. To assess the intensity of basal metabolism in adolescent elite athletes. Patients and methods. This study included 154 adolescent athletes (42 boys, 112 girls) aged 13–18 years (mean age: 15.3 ± 2.5 years). Basal metabolic rate (BMR) was measured in all participants using respiratory indirect calorimetry and the Harris–Benedict equation. Study design: single-center, cross-sectional, randomized, uncontrolled. Results. An increase in BMR was revealed in 79 (51%) participants, normal BMR – in 50 (33%) participants, and a decrease in BMR – in 25 (16%) participants. Increased BMR was statistically significantly more common in boys compared to girls (83% and 39% respectively, p = 0,01), whereas decreased BMR was more characteristic of girls compared to boys (20% and 4%, respectively, p = 0.001). Conclusion. Most adolescent athletes show an increase in BMR, which reflects an adaptation of the organism to high physical exertion. A decrease in BMR may indicate the presence of relative energy deficiency in athletes. The Harris–Benedict equation significantly underestimates the value of BMR in adolescent athletes and is not an alternative to respiratory indirect calorimetry when individual assessment of energy expenditure is necessary as part of biomedical support.

青少年运动员基础代谢率的评估

目标。评估青少年优秀运动员的基础代谢强度。患者和方法。本研究纳入154名13-18岁的青少年运动员(男42人，女112人)，平均年龄15.3±2.5岁。使用呼吸间接量热法和Harris-Benedict方程测量所有参与者的基础代谢率(BMR)。研究设计:单中心、横断面、随机、非对照。结果。79名(51%)参与者BMR增加，50名(33%)参与者BMR正常，25名(16%)参与者BMR下降。BMR增加在男孩中比女孩更常见(分别为83%和39%，p = 0.01)，而BMR降低在女孩中比男孩更常见(分别为20%和4%，p = 0.001)。结论。大多数青少年运动员显示出BMR的增加，这反映了机体对高体力消耗的适应。BMR的降低可能表明运动员存在相对能量不足。Harris-Benedict方程明显低估了青少年运动员BMR的价值，当个体能量消耗评估作为生物医学支持的一部分是必要的时，它不能替代呼吸间接量热法。关键词:儿童;高性能运动;基础代谢率
