The main purpose of the study was to establish, whether future cardiorespiratory fitness might be predicted by the level of muscular fitness at baseline. In this 3-year follow-up study, we recruited 240 secondary school girls at the age of 15 y, who were followed until the age of 17 y. Muscular fitness included the following tests: (i) standing broad jump (cm), (ii) sit-ups in 60 s (#) and (iii) squats in 60 s (#). Cardiorespiratory fitness was split into aerobic endurance (the 800-m run test) and speed endurance (the 400-m run test). Better performances in the 800-m run and the 400-m run tests at follow-up were correlated with higher levels of standing broad jump, sit-ups and squats in 60 s measured at baseline. In regression models adjusted for fat mass and maturity offset, standing broad jump, sit-ups and squats in 60 s were positively associated with the 800-m run test, while only standing broad jump remained significantly and positively associated with the 400-m run test. These data suggest that interventions enhancing muscular fitness should be recommended, as the effects are likely to be associated with future cardiorespiratory fitness in adolescent girls.
本研究的主要目的是确定基线时肌肉力量水平是否可以预测未来的心肺适能。在这项为期 3 年的随访研究中，我们招募了 240 名 15 岁的女中学生，随访至 17 岁。肌肉力量包括以下测试：（i）立定跳远（cm），（ii）60 秒仰卧起坐（#）和（iii）60 秒深蹲（#）。心肺适能分为有氧耐力（800 米跑测试）和速度耐力（400 米跑测试）。随访时 800 米跑和 400 米跑测试的更好成绩与基线时更高的立定跳远、60 秒仰卧起坐和深蹲成绩相关。在调整脂肪量和成熟度偏移的回归模型中，60 秒的立定跳远、仰卧起坐和深蹲与 800 米跑测试呈正相关，而只有立定跳远与 400 米跑测试呈显著正相关。这些数据表明，应该推荐增强肌肉力量的干预措施，因为这些效果可能与青少年女孩未来的心肺适能有关。
