초록
The aim of the present study was to investigate the long-termeffects of two relaxation techniques on choice reaction time (CRT), rating of perceived exertion (RPE), heart rate and oxygen consumption (VO_2) following intermittent high intensity exercise. Twenty-four physically active young male athletes were randomly divided into three groups, like, autogenic relaxation (AGR) group, progressive muscle relaxation (PMR) group and a control group. The experimental session consisted of two sessions with a long-termfour-week relaxation training in between. Each experimental session involved four bouts of intermittent exercise, consisting of. cycling at 60% VO_2max. for 10 minutes followed by 90% VO_2max. for 2 minutes. In between each bout of cycling, a 3-minute rest was given when choice reaction time (CRT) was conducted. Furthermore, RPE, heart rate, and VO_2 were measured at the last minute of each cycling bout Using 3(groups) x 2 (sessions) x 4 (trials)repeated measure ANOVA, the results revealed no significant interaction effects in any of the parameters. However, significant main effects for the session were found in heart rate, VO_2 and CRT, whereas significant main effects for trials were found for heart rate, RPE, and CRT. Hence, it is concluded that there was no significant effect of both the relaxation training on CRT and psychophysiological parameters,but moderately high intensity intermittent activity improved the reaction time performance.
Abstract
The aim of the present study was to investigate the long-termeffects of two relaxation techniques on choice reaction time (CRT), rating of perceived exertion (RPE), heart rate and oxygen consumption (VO_2) following intermittent high intensity exercise.

The experimental session consisted of two sessions with a long-termfour-week relaxation training in between.
