Abstract: We analyzed the relation between subjective fatigue by hard exercise and stress hormone and cytokine data. The subjects are eight healthy men who had exercise experience. In this experiment, hard exercise was carried out in the first place. After two-hour rest, a performance test was carried out. The blood test was conducted 4 times (before exercise, after exercise, rest, and a performance test). Subjective fatigue was indicated using visual analogue scale (VAS). After the hard exercise and performance test, VAS increased and showed the significant difference. Lactic acid, adrenaline, noradrenaline, growth hormone, IL-6, and IL-8 increased after each exercise and showed the significant difference. Subjective fatigue and the value of lactic acid, and IL-6 showed significant positive correlations. These results suggest that lactic acid, and IL-6 may become an index of fatigue in this exertion model.
