High-Intensity Interval Training (HIIT) and Constant-Intensity Endurance Training (CIET) improves peak oxygen uptake (V̇O) similarly in adults; but in children this remains unclear, as does the influence of maturity.
Thirty-seven boys formed three groups: HIIT (football; n = 14; 14.3 ± 3.1 years), CIET (distance runners; n = 12; 13.1 ± 2.5 years) and a control (CON) group (n = 11; 13.7 ± 3.2 years). Peak V̇O and gas exchange threshold (GET) were determined from a ramp test and anaerobic performance using a 30 m sprint pre-and-post a three-month training cycle.
The HIIT groups peak V̇O was significantly higher than the CON group pre (peak V̇O: 2.54 ± 0.63 l·min vs 2.03 ± 0.53 l·min, d = 0.88; GET: 1.41 ± 0.26 l·min vs 1.13 ± 0.29 l·min, d = 1.02) and post-training (peak V̇O: 2.63 ± 0.73 l·min vs 2.08 ± 0.64 l·min, d = 0.80; GET: 1.32 ± 0.33 l·min vs 1.15 ± 0.38 l·min, d = 0.48). All groups showed a similar magnitude of change during the training (p > 0.05).
HIIT was not superior to CIET for improving aerobic or anaerobic parameters in adolescents. Secondly, pre- and post-pubertal participants demonstrated similar trainability.
高强度间歇训练（HIIT）和等强度耐力训练（CIET）在成年人中同样能提高峰值摄氧量（V̇O）；但在儿童中情况尚不清楚，成熟度的影响也是如此。
37 名男孩分为三组：HIIT（足球；n = 14；14.3 ± 3.1 岁）、CIET（长跑运动员；n = 12；13.1 ± 2.5 岁）和对照组（CON）（n = 11；13.7 ± 3.2 岁）。峰值 V̇O 和气体交换阈值（GET）通过斜坡测试和 30 米冲刺的无氧性能来确定，在三个月的训练周期前后进行。
HIIT 组的峰值 V̇O 明显高于 CON 组，训练前（峰值 V̇O：2.54 ± 0.63 l·min vs 2.03 ± 0.53 l·min，d = 0.88；GET：1.41 ± 0.26 l·min vs 1.13 ± 0.29 l·min，d = 1.02）和训练后（峰值 V̇O：2.63 ± 0.73 l·min vs 2.08 ± 0.64 l·min，d = 0.80；GET：1.32 ± 0.33 l·min vs 1.15 ± 0.38 l·min，d = 0.48）。所有组在训练期间的变化幅度相似（p > 0.05）。
HIIT 在提高青少年的有氧或无氧参数方面并不优于 CIET。其次，青春期前和青春期后的参与者表现出相似的可训练性。
