Comparison of physical fitness and heart rate response during game with the level of performance in middle - aged male recreational badminton players

This study measured physical fitness by 6 items and heart rate response in a doubles game by dividing 62 middle-aged men with age and grade, who have participated in tournament of life-giving athletic association in order to offer a basic data on importance of regular exercises and calculation of the optimal intensity in badminton game. This study carried out a doubles game between grade B and C, and measured the heart rate at rest and at 15 seconds intervals during game, and calculated the relative intensity of sports based on the maximum heart rate. In the reason of participation in badminton exercise program, 「for maintaining health and promoting physical strength」 was the most by 62 percents. Three times or four times a week was 56.5 % in the exercise frequency, and the duration of exercise for 60 to 90 minutes showed the highest value (64.5 %). There was the significant difference (p＜0.05) among groups with age and grade on left grip muscular strength, lower back muscular strength, sit-ups performance, and Harvard step test. In the relative exercise intensity based on the maximum heart rate in the game, there wasn`t any significant difference between Grade B and C, and groups by grade, but the relative exercise intensity was the range from 55 percents to 75 percents. In the relative exercise intensity based upon the maximum heart rate between 2 minutes interval in game of Grade B and C, there was the significant difference (p＜0.05) between groups while going on the game for 8 minutes to 12 minutes. Especially, C-grade of 40-aged subjects showed a high intensity by 85.36(± 17.90)% of the maximum heart rate at 12-14 minutes during game. Exercise intensity was the significant difference (p＜0.05) between two groups with age while going on the game for 32 minutes to 38 minutes in game with same grade. Especially, B-graded of 40-aged subjects showed a high intensity by 92.47(±3.80) % of the maximum heart rate at 36-38 minutes during game. In this result, badminton exercise could be suggested the effective exercise program for improvement of physical fitness in middle-aged male subjects. But it is thought to be controled of exercise intensity for middle-aged men to participate in badminton game or tournament by their athletic ability.
