| Abstract |
The purpose of this study was to examine the reproducibility of comfortable self-paced jogging by using physiological and psychological variables, which consisted of pitch, speed, heart rate (HR), rat...ing perceived exertion (RPE) and mood alteration. Seventeen male nonrunners, aged 24.1+-2.52 years old, voluntarily participated in this study. All volunteers jogged at their own pace for 15 minutes using a treadmill prepared by us, and then the same subjects were retested which was carried out either one or two weeks later. The pitch, speed and HR as physiological variables and RPE rating the subjective exercise intensity were all measured while jogging. In addition, their mood state as a psychological variable was assessed by a mood check list (MCL-3) and an MCL short form, which were both developed by Hashimoto et al. (1992,1993b), before, during, and after jogging. Regarding the physiological variables, there was a significantly high correlation coefficient between the test and retest for speed (r=0.852, p<.001) and HR (r=0.844, p<.001), and a moderate correlation coefficient for pitch (r=0.595, p<.012). On the other hand, "Pleasantness" (r=0.693, p<.001). "Relaxation" (r=0.500, p<.041) and "Satisfaction" (r=0.628, p<.006) as a mood state psychological variable and RPE (r=0.637, P<.006) indicated a significantly moderate correlation coefficient. These results thus indicated that the reproducibility of comfortable self-paced jogging was confirmed in terms of both physiological and psychological variables. In particular, it was suggested that comfortable self-paced jogging was strongly affected by speed and heart rate.show more
