Acute effect of different trainings in the variability of the heart rate of young football players

Abstract

To determine the time-domain (SDNN, RMSSD) of heart rate variability (HRV) and heart rate (HR) of young football players in different training sessions. Method: 15 football players voluntarily participated (mean age = 15.5 ± 0.5 years, height= 171.1 ± 7.9 cm, weight= 62.4 ± 8.9 kg, BMI= 21.2 ± 1.9 kg/m2). They performed three different training: speed, coordination, and match formation. The HRV and HR of the participants were measured during warm-up, main training, and cool-down in each of the three different training sessions. Results: There was a significant interaction between time and intervention on RMSSD (Frmat= 2.983) and HR (Frmat t= 4.894). The results show that HR and HRV are affected differently by diverse training practices in football.
