■本研究旨在比较两种同时训练(CT)方案对中学生身体素质的影响。
■对157名中学生(年龄=12.48±0.34,n=90名女性)进行了为期12周的准实验前测/后测研究,分为三组:CT组A(CT-0h)在每次体育课中接受了抗阻训练(RT)和有氧训练(AT),CT组B(CT-48h)在两个独立的体育课中分别接受RT和AT,间隔48h,对照组(Con)未接受培训。训练每周进行两次。测试指标包括通过估计的VO2max和20m穿梭跑(圈数)测量的心肺健康(CRF),以及通过跳远评估的肌肉力量,垂直跳跃,和握力。
■与基线值相比,干预组的VO2max估计值和肌肉力量显着增加(p<0.05)。CT-0h和CT-48h组在20m穿梭跑(圈数)中均显示出显着改善(平均差异:8.88圈,p<0.01;平均差:4.81圈,p分别<0.01),立定跳远(平均差:6.20厘米,p<0.01;平均差:3.68cm,p分别<0.01),垂直跳跃(平均差:4.95厘米,p<0.01;平均差:4.04cm,p分别<0.01),和手握力(平均差:11.17千克,p<0.01;平均差:6.99kg,p分别<0.01)。CT-0h组显着增加了估计的VO2max(平均差异:1.47ml/kg/min,p<0.01)与CT-48h组比拟。
■两种CT方案都有效改善了青少年的体质指标。然而,在同一体育课中整合RT和AT的程序在青少年的CRF中表现出优异的增强效果。
UNASSIGNED: This study aimed to compare the effects of two concurrent training (CT) protocols on the physical fitness of middle school students.
UNASSIGNED: A 12-week quasi-experimental pre-test/post-test study was conducted with 157 middle school students (age = 12.48 ± 0.34, n = 90 females) divided into three groups: CT group A (CT-0h) received combined resistance training (RT) and aerobic training (AT) in each physical education session, CT group B (CT-48h) received RT and AT across two separate physical education classes 48 h apart, and a control group (Con) received no training. Training occurred twice a week. Test indicators included cardiorespiratory fitness (CRF) measured by estimated VO2max and 20 m shuttle run (laps), as well as muscle strength assessed through long jump, vertical jump, and handgrip strength.
UNASSIGNED: The intervention groups exhibited significant increases in estimated VO2max and muscle strength compared to their baseline values (p < 0.05). Both CT-0h and CT-48h groups demonstrated significant improvements in 20 m shuttle run (laps) (mean difference: 8.88 laps, p < 0.01; mean difference: 4.81 laps, p < 0.01, respectively), standing long jump (mean difference: 6.20 cm, p < 0.01; mean difference: 3.68 cm, p < 0.01, respectively), vertical jump (mean difference: 4.95 cm, p < 0.01; mean difference: 4.04 cm, p < 0.01, respectively), and handgrip strength (mean difference: 11.17 kg, p < 0.01; mean difference: 6.99 kg, p < 0.01, respectively). CT-0h group exhibited significantly increased estimated VO2max (mean difference: 1.47 ml/kg/min, p < 0.01) compared to the CT-48h group.
UNASSIGNED: Both CT programs effectively improved adolescents\' physical fitness indicators. However, the program that integrated RT and AT within the same physical education class demonstrated superior enhancement in adolescents\' CRF.
