Abstract

Purpose: To evaluate the effect of maturity status on the autonomic nervous system at rest and recovery after short-term, high-intensity exercise in adolescents. Methods: A biological maturity age was estimated in 27 males by calculating the years from peak height velocity (PHV) using a multiple regression equation. Subjects were divided into two groups: pre-PHV (years from PHV < 0.49), N = 14, mean age = 12.29 ± 0.91 yr; post-PHV (years from PHV > 0.5, N = 13, mean age = 15.12 ± 0.76 yr). HR variability was used to evaluate autonomic function. ECG tracings were collected during 5 min at rest and recovery after a Wingate test and were analyzed in the frequency domain (low-frequency (LF), high-frequency (HF), LF/KF, total power (TP)). Data are presented as natural logarithms (LN). Results: Changes in HR from HR peak during exercise to HR measured at minute 4 after exercise (ΔHR4) were significantly greater in the pre-PHV group (84.31 ± 17.58 bpm) compared with the post-PHV group (69.42 ± 17.63 bpm). There were no significant differences in resting HR variability between pre- and post-PHV groups (P > 0.05). Significant group × time interactions were found for LF LN (ms 2 ) and TP LN (ms 2 ) measured during recovery (P < 0.05). Post hoc tests showed that the pre-PHV group had significantly higher postexercise LF LN (5.02 ± 0.97 vs 4.19 ± 0.79) and TP LN (6.36 ± 1.02 vs 5.62 ± 0.65) compared with the post-PHV group. When postexercise LF LN (ms 2 ) was normalized for TP LN (ms 2 ), there were no significant differences between groups (P > 0.05). Conclusion: The pre-PHV group had higher total HR variability than the post-PHV group after a Wingate test, suggesting that maturity status significantly affects total HR variability during recovery after high-intensity exercise.
