摘要

此前有研究表明,生物成熟(BM)可能与儿科人群的心脏自主神经恢复(CAR)有关。然而,这种影响尚未得到证实。我们的目的是研究生理成熟对女子排球运动员自律神经恢复的影响。我们对 38 名排球运动员进行了实验研究,其中包括 20 名女孩(年龄:[11.6 ± 2.1] 岁)和 18 名女孩(年龄:[24.5 ± 5.5] 岁)。此外,我们还评估了女孩的身高峰值速度(PHV)。我们进行了重复短跑训练(3 轮 6 次短跑,中间穿插 5 分钟的被动休息)。我们使用短程无线电遥测技术,通过应用 60 秒至 300 秒心率恢复指数(HRR-Index),分析了重复短跑训练期间(第一轮和第二轮结束时)和训练后(第三轮结束后)的心率恢复情况。与女生相比,女生的心率恢复指数更高(第 2 轮:60 秒、120 秒、240 秒和 300 秒,P < 0.005)。对 BM 进行的分组分析表明,与早期高血压组和高血压期间组相比,处于晚期高血压组的人表现出更优越的 CAR。(60 秒至 300 秒,η2p > 0.4,p < 0.05)。处于期间-高血压阶段的受试者优于处于早期-高血压阶段的受试者(240 秒 á 300 秒,η2 p > 0.4,p < 0.05)。我们得出结论,生物成熟度对心脏自主神经的恢复有重要影响。

Influence of biological maturation on cardiac autonomic recovery in female volleyball players during & after repeated sprints training: An experimental trial

Influence of biological maturation on cardiac autonomic recovery in female volleyball players during & after repeated sprints training: An experimental trial

Previously, it was suggested that biological maturation (BM) could be linked to cardiac autonomic recovery (CAR) in the pediatric population. However, this influence hasn’t been confirmed yet. Our aim was to investigate the impact of BM on CAR in female volleyball players. Experimental study with a sample of 38 volleyball players, comprising 20 girls (age: [11.6 ​± ​2.1] years) and 18 women (age: [24.5 ​± ​5.5] years), we analyzed BM, comparing maturing subjects (girls) with mature subjects (women). Additionally, we assessed peak height velocity (PHV) in girls. We conducted a training session involving repeated sprints (3 rounds of 6 sprints interspersed by 5 ​min [min] of passive rest). Using short-range radio telemetry, we analyzed CAR during (at the end of the 1st and 2nd rounds) and after (following the 3rd round) the training session of repeated sprints by applying the 60-s to 300-s heart rate recovery index (HRR-Index). Girls exhibited superior CAR compared to women (round 2: 60-s, 120-s, 240-s, and 300-s, p ​< ​0.005). Subgroup analyses of BM indicated that individuals in the Late-PHV stage demonstrated superior CAR compared to those in the Early-PHV and During-PHV groups. (60-s to 300-s, η2p ​> ​0.4, p ​< ​0.05). Subjects in the During-PHV stage were superior to those in the Early-PHV stage (240-s á 300-s, η2 p ​> ​0.4, p ​< ​0.05). We have concluded that biological maturation has a significant impact on cardiac autonomic recovery.
