Effect of "touch rugby" training on the cardiovascular autonomic control in sedentary subjects

This study aimed to explore the effects of “touch-rugby” training on the cardiovascular autonomic control in sedentary subjects. 22 adults (30–64 years old) were included in this study. Before (pre-test) and after (post-test) the period of training, cardio-respiratory recordings were achieved at rest and during a graded maximal exercise on a treadmill. The Smoothed-Pseudo-Wigner-Ville Distribution provided instantaneous time frequency components of RR intervals and systolic blood pressure variability in low- and high-frequency bands. The baroreflex sensitivity was assessed in low-frequency and high-frequency bands. Between pre-test and post-test, resting heart rate (74±10 vs. 69±12 beats.min −1 , p −1 , p
