This study aims to explore: (1) the validity of post-exercise ultra-short-term heart rate variability (HRV) after two different bouts of repeated sprint ability test (RSA), and (2) the relationship between HRV measure and RSA performance. Twenty adolescent male futsal players voluntarily participated in this study (age: 17.65 ± 1.81 years, body height: 170.88 ± 4.98 cm, body weight: 61.78 ± 4.67 kg). The participants performed a standard RSA test (RSA) and an RSA test with a 10% decrement of the best sprint time test (RSA) on two separate occasions within a week. On both occasions, a 5-min resting electrocardiography was administered pre- and post-RSA exercise protocols. The first 30-s (HRV), 60-s (HRV), and 60-120-s (HRV) were extracted and used to compare with the standard of 5-min HRV recording (HRV). The natural logarithm (ln) of the standard deviation of normal-to-normal intervals (SDNN) and root mean square of successive normal-to-normal interval differences (RMSSD) HRV indices were utilised to establish intraclass correlation coefficient (ICC), coefficient of variation (%CV), and Pearson product-moment correlation (). Results revealed the ICC values of HRV lnSDNN (RSA = 0.77-0.88; RSA = 0.41-0.71) and lnRMSSD (RSA = 0.81-0.86; RSA = 0.57-0.82). Furthermore, significantly positive correlations between best sprint time and post-exercise HRV indices were found in lnSDNN (= 0.47-0.62; < 0.05) and lnRMSSD (= 0.45; < 0.05). Additionally, a large CV of lnSDNN (RSA = 32%-45%; RSA = 29%-39%), lnRMSSD (RSA = 50%-66%; RSA = 48%-52%), and ratio (RSA = 45%-126%; RSA = 27%-45%) was found after the RSA protocols. In conclusion, the number of bouts of RSA exercise potentially influences the agreement of post-exercise time-domain HRV indices to standard HRV measure.
（1）两种不同重复冲刺能力测试（RSA）后运动后超短期心率变异性（HRV）的有效性；（2）HRV 测量与 RSA 性能之间的关系。20 名青少年男性足球运动员自愿参加了这项研究（年龄：17.65±1.81 岁，身高：170.88±4.98cm，体重：61.78±4.67kg）。参与者在一周内的两次不同时间内分别进行了标准 RSA 测试（RSA）和最佳冲刺时间测试（RSA）减少 10%的 RSA 测试。在两次情况下，RSA 运动前后进行了 5 分钟的休息心电图检查。提取前 30 秒（HRV）、60 秒（HRV）和 60-120 秒（HRV）并与 5 分钟 HRV 记录（HRV）标准进行比较。利用标准差值（SDNN）和连续正常到正常间隔差的均方根（RMSSD）的自然对数（ln）建立了 HRV 指数的组内相关系数（ICC）、变异系数（%CV）和皮尔逊乘积矩相关（）。结果显示，HRV lnSDNN（RSA=0.77-0.88；RSA=0.41-0.71）和 lnRMSSD（RSA=0.81-0.86；RSA=0.57-0.82）的 ICC 值。此外，在最佳冲刺时间和运动后 HRV 指数之间发现了显著的正相关lnSDNN（=0.47-0.62；<0.05）和 lnRMSSD（=0.45；<0.05）。此外，在 RSA 协议后，lnSDNN（RSA=32%-45%；RSA=29%-39%）、lnRMSSD（RSA=50%-66%；RSA=48%-52%）和比率（RSA=45%-126%；RSA=27%-45%）的 CV 较大。总之，RSA 运动的次数可能会影响运动后时域 HRV 指数与标准 HRV 测量的一致性。
