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.
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.
RPE was significantly lower after SSG 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.
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.
已有研究表明，休闲足球是一项极具激励性和社交性的活动，能使久坐不动的健康和不健康受试者的健康相关指标得到显著改善。本研究的目的是比较小型足球比赛（SSG）和重复冲刺训练（RST）课后急性副交感神经再激活情况。
八名青春期后未经训练的青少年（年龄15.8±0.6岁，体重59.1±3.7千克，身高1.7±0.1米）以平衡顺序进行了RST、SSG和对照课。评估了时域和频域的心率变异性（HRV）指标、心率恢复情况以及主观用力感觉等级（RPE）。
与RST相比，SSG后的RPE显著更低（P=0.02，效应量=1.1）。RST后平均R-R间期显著缩短（差值：-19.6%，P<0.01，效应量=1.7），SSG后也显著缩短（-19.2%，P<0.01，效应量=2.3）。RST后SDNN也显著降低（-26.6%，P=0.02，效应量=1.8），SSG后同样降低（-37.8%，P=0.01，效应量=1.1）。对于RMSSD，仅在SSG后观察到显著降低（48%，P=0.01，效应量=1.3）。对照课后所有HRV指标均无显著变化。
SSG和RST引发了相似的高心率反应。RST和SSG后早期恢复过程中均观察到副交感神经再激活较低。这些结果对于希望为久坐不动的受试者开具重复冲刺训练或小型比赛处方的临床医生尤为重要。
