Abstract

Objective

To investigate the impact of high-intensity interval training (HIIT) on autonomic regulation in obese adolescents.

Methods

The study sample included 26 adolescents with obesity, of both sexes, aged 12 ± 2 years, divided into a control group (n = 11) and a training group (n = 15). Anthropometric assessments included body weight and height for the calculation of body mass index (BMI), as well as sitting height to estimate Maturity Offset. Body fat percentage was obtained through dual-energy X-ray absorptiometry (DEXA). Heart rate variability (HRV) was analyzed with the Polar RS800 heart rate monitor, using time-domain, frequency-domain, and Poincaré plot parameters. The intervention involved an HIIT protocol on a treadmill over 20 weeks, performed three times a week, consisting of a warm-up, followed by six 40-s high-intensity bouts at a running speed equivalent to 100 % of the peak heart rate determined by a maximal effort test, interspersed with 20-s passive recovery intervals. Each session also included 4 min of passive recovery at a constant speed of 5 km/h or 50 % of the training speed, after which the training cycle was repeated. Statistical tests included the Shapiro-Wilk test, independent t-tests, and repeated measures ANOVA, conducted using SPSS version 13.0.

Results

After the 20-week training period, no significant changes were found in HRV indices across the time-domain, frequency-domain, or Poincaré plot analyses.

Conclusion

A 20-week HIIT protocol did not lead to measurable changes in cardiac autonomic modulation in adolescents with obesity.

高强度间歇训练对肥胖青少年心脏自主神经调节的影响

目的探讨高强度间歇训练（HIIT）对肥胖青少年自主神经调节的影响。方法选取肥胖青少年26例，年龄12±2岁，男女均可，分为对照组（n = 11）和训练组（n = 15）。人体测量学评估包括体重和身高，用于计算身体质量指数（BMI），以及坐姿高度，用于估计成熟度偏移。通过双能x线吸收仪（DEXA）获得体脂率。心率变异性（HRV）采用Polar RS800心率监测仪，采用时域、频域和poincarcarr图参数进行分析。干预包括在跑步机上进行为期20周的HIIT方案，每周进行三次，包括热身，然后是6次40秒的高强度比赛，跑步速度相当于最大努力测试确定的100%的峰值心率，穿插20秒的被动恢复间隔。每次训练还包括4分钟的被动恢复，以5公里/小时的恒定速度或训练速度的50%进行，之后重复训练周期。统计检验包括Shapiro-Wilk检验、独立t检验和重复测量方差分析，采用SPSS 13.0版本进行。结果经过20周的训练，HRV指数在时域、频域和poincarcarr图分析中均无显著变化。结论：20周HIIT方案没有导致肥胖青少年心脏自主神经调节发生可测量的变化。
