The purpose of this study was to investigate heart rate and walking and running steps during tennis training in adult men. Four healthy males (age 47.3 ± 14.5yr, height l.68 ± 0.07cm, body weight 70.1 ± 11.5kg, BMI 24.9 ± 2.5kg/m2, percent body fat 19.9 ± 3.1%, lean body mass 55.9 ± 7.4kg) participated in this study. Each subject provided written informed consent before participation. Heart rate (HR) and walking and running step data were measured by means of heart rate monitor (Heart Rate Monitor S710 Polar, Finland) and pedometer (Digi-Walker EM-180 Yamasa, Tokyo). As results, 1) the mean value of the number of walking and running steps and distance were about 5000 steps and 3000 m, 2) the mean value of maximum HR, %HRmax, average HR and %HRmax were about 160 bpm, 90%HRmax, 120 bpm and 70%HRmax, respectively. It is suggesed that tennis training measured in this study were underwent on exercise intensity about 70%HRmax. In short, the tennis training seemed to have been connected with the improvement of endurance ability and excessive body fat, and it was indicated to be sports activity which can contribute to the prevention of lifestyle-related disease.
