This paper is aimed at comparing the changes of immune hormones(IgG, IgA, IgM), stress hormone (Cortisol), muscle damage hormone (CK) and muscle-growth hormone (IGF-1) when resistance exercise is put on legs through different muscle contraction type. 14 male with more than 5 years of resistance exercise experience Isotonic squat, isotonic squat, and jump squat were done for one minute each and a total of five sets were performed with a thirty-second break between each set. Also, blood was taken in a stable condition and after each exercise to analyze immunity-related hormones (IgG, IgA, IgM), stress hormone (Cortisol), muscle damage hormone (CK) and muscle-growth hormone (IGF-1). One-way ANOVA through SPSS(Ver 15.0) was made to prove the hormone responses depending on different ways of muscular contraction. Tukey was used for post-hoc analysis. Statistical significance level was a=.05. Also, the analysis of the immune hormone depending on the form of muscular contraction showed an increase in IgG and IgA compared to the time before the exercise, but the difference was not significant. The result of stress hormone analysis showed that there was a meaningful increase of cortisol hormone in all the three ways compared to pre-exercise (P<.01). The analysis of damaged muscle hormone showed meaningfully increased CK in general compared to before the experiment (P<.01). In the case of muscle growth hormone, there was a meaningful increase between difference was not significant.
