ABSTRACT

ABSTRACT

The 800-m (m) run is part of Physical Education classes in Cameroon, after which arrhythmias may occur during recovery. Hence, this study aimed at determining relationship between 800-m run loads on cardiac autonomic recovery among school adolescents. Forty-two male adolescents (aged [17 â± â1] years) performed 800-m. Post-exercise heart rate variability (HRV) was recorded during 5-min (min) (HRV5-min) and 15-min (HRV15-min) in time Standard deviation of normal to normal (SDNN); Root mean square of successive differences (RMSSD) and frequency domain (LH Low frequency, HF High frequency, TP Total power). Rating of Perceived Exertion (RPE) and blood lactate concentration (BLa) were measured after exercise. In HRV5-min, RPE was associated with SDNN (r â= â-0.44, p â< â0.01) and RMSSD (r â= â-0.38, p â< â0.05). BLa was correlated with SDNN (r â= â-0.38, p â< â0.05) and RMSSD (r â= â-0.56, p â< â0.001) in the time-domain, LF (r â= â-0.64, p â< â0.001), HF (r â= â-0.58, p â< â0.001) and TP (r â= â-0.61, p â< â0.001) in frequency-domain. Moreover, RPE was correlated with LF (r â= â-0.44, p â< â0.01), TP (r â= â-0.49, p â< â0.01) while exercise duration with HF (r â= â-0.38, p â< â0.05). In HRV15-min, BLa was correlated with RMSSD (r â= â-0.53, p â< â0.001) and SDNN (r â= â-0.68, p â< â0.001). RPE was negatively correlated SDNN (r â= â-0.53, p â< â0.01) and RMSSD (r â= â-0.44, p â< â0.01). BLa was associated with HF (r â= â-0.55, p â< â0.001), TP (r â= â-0.50, p â< â0.01) and RPE with LF (r â= â-0.51, p â< â0.01), HF (r â= â-0.50, p â< â0.01), TP (r â= â-0.49, p â< â0.01). In addition, exercise duration was negatively linked to HF (r â= â-0.36, p â< â0.05). This study outlined that in untrained adolescents an increase of 800-m loads is associated with a slow vagal indexes of HRV during the recovery.
