We aimed to examine changes in resting heart rate variability, submaximal exercising heart rate (HRex), countermovement-jump height (CMJ), perceptual wellbeing, and internal load throughout preparatory training in elite women's volleyball players. We also aimed to determine which HRV measurement position (supine vs. seated) provided greater associations with the various markers of training adaptation. Thirteen players (age = 25.8 ± 3.0 years, height = 178.1 ± 6.7 cm, weight = 69.7 ± 7.6 kg) were monitored throughout four successive training camps preceding the Asia Cup. Daily measures of the root-mean square of successive differences were used to calculate the mean (LnRMSSD_M) and coefficient of variation (LnRMSSD_CV) for each camp. Averages were also determined for Hooper's Index and session ratings of perceived exertion (sRPE). HRex and CMJ were tested at the start of each camp. RESULTS: Seated LnRMSSD_CV, HRex, CMJ, and sRPE increased at camp 3 (p < 0.05), then reverted to values similar to camp 2. Changes in seated LnRMSSD_M were associated with changes in HRex (r = -0.68 to -0.71, p < 0.05). Occasional associations (p < 0.05) were observed between LnRMSSD_CV and Hooper's Index (r = 0.59) and CMJ (r = -0.57), and changes in HRex (r = 0.69) and HRR (r = -0.62). CONCLUSIONS: A reduced cardiorespiratory response to a standardized submaximal workload was associated with increased seated LnRMSSD_M. Higher seated LnRMSSD_CV was observed in response to increased sRPE and was often associated with decrements in various status markers. Seated LnRMSSD provided more associations with indicators of training adaptation than supine measures.

我们旨在检查精英女排运动员在整个准备训练过程中静息心率变异性、次最大运动心率 (HRex)、反跳高度 (CMJ)、知觉健康和内部负荷的变化。我们还旨在确定哪种 HRV 测量位置（仰卧与坐姿）与各种训练适应标志有更大的关联。在亚洲杯之前的四个连续训练营中，对 13 名球员（年龄 = 25.8 ± 3.0 岁，身高 = 178.1 ± 6.7 厘米，体重 = 69.7 ± 7.6 公斤）进行了监测。连续差异的均方根的每日测量值用于计算平均值 (LnRMSSD _M ) 和变异系数 (LnRMSSD _CV) 每个营地。还确定了胡珀指数和感知劳累的会话评级 (sRPE) 的平均值。HRex 和 CMJ 在每个训练营开始时都接受了测试。结果：坐姿 LnRMSSD _CV、HRex、CMJ 和 sRPE 在第3 阵营增加（p  < 0.05），然后恢复到与阵营 2 相似的值。坐姿 LnRMSSD _{M 的}变化与 HRex 的变化相关（r  = -0.68 到-0.71 , p  < 0.05)。 在 LnRMSSD _CV和胡珀指数 ( r  = 0.59) 和 CMJ ( r  = -0.57)之间观察到偶尔的关联 ( p < 0.05) ，以及 HRex ( r  = 0.69) 和 HRR ( r = -0.62）。结论：对标准化次最大工作负荷的心肺反应降低与坐姿 LnRMSSD _M增加有关。观察到更高位的 LnRMSSD _CV响应增加的 sRPE，并且通常与各种状态标记的减少有关。与仰卧测量相比，坐姿 LnRMSSD 提供了更多与训练适应指标的关联。
