Twenty adolescent male futsal players voluntarily participated in this study (age: 17.65\u2009\u00b1\u20091.81 years, body height: 170.88\u2009\u00b1\u20094.98 cm, body weight: 61.78\u2009\u00b1\u20094.67 kg). The participants performed a standard RSA test (RSA\n                    <jats:sub>standard<\/jats:sub>\n                    ) and an RSA test with a 10% decrement of the best sprint time test (RSA\n                    <jats:sub>10%decrement<\/jats:sub>\n                    ) 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\n                    <jats:sub>ust30s<\/jats:sub>\n                    ), 60-s (HRV\n                    <jats:sub>ust60s<\/jats:sub>\n                    ), and 60\u2013120-s (HRV\n                    <jats:sub>ust1\u22122min<\/jats:sub>\n                    ) were extracted and used to compare with the standard of 5-min HRV recording (HRV\n                    <jats:sub>criterion<\/jats:sub>\n                    ). 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\n                    <jats:sub>2,1<\/jats:sub>\n                    ), coefficient of variation (%CV), and Pearson product-moment correlation ( r). Results revealed the ICC values of HRV\n                    <jats:sub>ust<\/jats:sub>\n                    lnSDNN (RSA\n                    <jats:sub>standard<\/jats:sub>\n                    \u2009=\u20090.77\u20130.88; RSA\n                    <jats:sub>10%decrement<\/jats:sub>\n                    \u2009=\u20090.41\u20130.71) and lnRMSSD (RSA\n                    <jats:sub>standard<\/jats:sub>\n                    \u2009=\u20090.81\u20130.86; RSA\n                    <jats:sub>10%decrement<\/jats:sub>\n                    \u2009=\u20090.57\u20130.82). Furthermore, significantly positive correlations between best sprint time and post-exercise HRV\n                    <jats:sub>ust<\/jats:sub>\n                    indices were found in lnSDNN ( r\u2009=\u20090.47\u20130.62; p\u2009&lt;\u20090.05) and lnRMSSD ( r\u2009=\u20090.45; p\u2009&lt;\u20090.05). Additionally, a large CV of lnSDNN (RSA\n                    <jats:sub>standard<\/jats:sub>\n                    \u2009=\u200932%\u201345%; RSA\n                    <jats:sub>10%decrement<\/jats:sub>\n                    \u2009=\u200929%\u201339%), lnRMSSD (RSA\n                    <jats:sub>standard<\/jats:sub>\n                    \u2009=\u200950%\u201366%; RSA\n                    <jats:sub>10%decrement<\/jats:sub>\n                    \u2009=\u200948%\u201352%), and ratio (RSA\n                    <jats:sub>standard<\/jats:sub>\n                    \u2009=\u200945%\u2013126%; RSA\n                    <jats:sub>10%decrement<\/jats:sub>\n                    \u2009=\u200927%\u201345%) 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\n                    <jats:sub>ust<\/jats:sub>\n                    indices to
