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 1 and 2 rounds) and after (following the 3 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, < 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, > 0.4, < 0.05). Subjects in the During-PHV stage were superior to those in the Early-PHV stage (240-s á 300-s, > 0.4, < 0.05). We have concluded that biological maturation has a significant impact on cardiac autonomic recovery.
此前有研究表明，在儿科人群中，生物成熟度（BM）可能与心脏自主神经恢复（CAR）有关。然而，这种影响尚未得到证实。我们的目的是研究BM对女排运动员CAR的影响。对38名排球运动员进行实验研究，其中包括20名女孩（年龄：[11.6 ± 2.1]岁）和18名女性（年龄：[24.5 ± 5.5]岁），我们分析了BM，将成熟中的受试者（女孩）与成熟受试者（女性）进行比较。此外，我们评估了女孩的身高增长高峰速度（PHV）。我们进行了一次训练课，包括重复冲刺（3组，每组6次冲刺，中间穿插5分钟的被动休息）。使用短程无线电遥测技术，我们通过应用60秒至300秒心率恢复指数（HRR-Index），在重复冲刺训练期间（第1轮和第2轮结束时）和之后（第3轮之后）分析CAR。与女性相比，女孩表现出更好的CAR（第2轮：60秒、120秒、240秒和300秒，<0.005）。BM的亚组分析表明，处于身高增长高峰后期阶段的个体比处于身高增长高峰早期和身高增长高峰期间组的个体表现出更好的CAR（60秒至300秒，>0.4，<0.05）。处于身高增长高峰期间阶段的受试者优于处于身高增长高峰早期阶段的受试者（240秒至300秒，>0.4，<0.05）。我们得出结论，生物成熟度对心脏自主神经恢复有显著影响。
