Abstract

Heart rate response to a short (4 s) bicycle exercise test during maximal inspiratory apnea was used to assess vagal activity (VA). This study aims to evaluate the role of age, sex and physical activity pattern on VA. A total of 148 subjects, divided into athletes (N = 90) and non-athletes (N = 58) were tested. No correlation was found between age (range from 15 to 42 years) and VA in the male and female athletes (P greater than 0.05). No gender effect could be identified. In spite of a slight tendency toward higher VA in athletes, no significant differences could be found between the two groups.
