OBJECTIVE
To investigate the impact of physical growth, body adiposity and lifestyle on cardiorespiratory fitness and muscle strength of pubescent and post-pubescent adolescents.
METHODS
Cross-sectional study with 1132 adolescents (14-19 years) in Brazil. Aerobic fitness was measured using the modified Canadian Aerobic Fitness Test. Muscle strength was assessed using manual dynamometer. Maturational stages were defined through the Tanner criteria.
RESULTS
Boys at pubertal maturation stage showed higher VOmax values than those at the post-pubertal stage when the influence of body adiposity and lifestyle was disregarded. Girls at pubertal maturation stage showed higher VOmax values than those in the post-pubertal stage when the influence of age was disregarded. For muscle strength, no significant differences were found.
CONCLUSIONS
The variables that influence the association between VOmax and maturational stage are different for boys and girls.
目的
探讨身体生长、体脂率和生活方式对青春期及青春期后青少年心肺适能和肌肉力量的影响。
方法
对巴西1132名14 - 19岁青少年进行横断面研究。采用改良的加拿大有氧适能测试来测量有氧适能。使用手动测力计评估肌肉力量。通过坦纳标准定义成熟阶段。
结果
在不考虑体脂率和生活方式影响的情况下，青春期成熟阶段的男孩比青春期后阶段的男孩具有更高的最大摄氧量值。在不考虑年龄影响的情况下，青春期成熟阶段的女孩比青春期后阶段的女孩具有更高的最大摄氧量值。对于肌肉力量，未发现显著差异。
结论
影响最大摄氧量与成熟阶段之间关联的变量在男孩和女孩中有所不同。
