BACKGROUND: It has been shown that recreational soccer was a highly motivating and social activity which produces large improvements in health-related indices in sedentary healthy and unhealthy subjects. The purpose of this study was to compare the acute parasympathetic reactivation after small-sided soccer games (SSG) and repeated sprints training (RST) sessions.
METHODS: Eight post-pubertal untrained adolescents (age 15.8 ± 0.6 years, body mass 59.1 ± 3.7 kg, height 1.7 ± 0.1 m) performed a RST, SSG and a control session in a counterbalanced order. Heart rate variability (HRV) indices in time and frequency domain, heart rate recovery and rating of perceived exertion (RPE) were evaluated.
RESULTS: RPE was significantly lower after SSGs compared with RST (P = 0.02, ES = 1.1). There was a significant decrease in mean R-R intervals after RST (difference: -19.6%, P < 0.01, ES = 1.7) and after SSG (-19.2%, P < 0.01, ES = 2.3). A significant decrease was also noted in SDNN after RST (-26.6%, P = 0.02, ES = 1.8) and SSG (-37.8%, P = 0.01, ES = 1.1). For RMSSD, a significant decrease was observed only after SSG (48%, P = 0.01, ES = 1.3). No significant change in all HRV indices after the control condition.
CONCLUSIONS: SSG and RST elicited high and similar heart rates responses. A low parasympathetic reactivation during early recovery was noted after both RST and SSG. These results were important especially for clinician looking to prescribe repeated sprint or small-sided game for sedentary subjects.
