This paper is aimed at comparing the changes of immune hormones(IgG), stress hormone (Cortisol), muscle damage hormone (CK) and muscle-growth hormone (IGF-1,Testosterone) when resistance exercise is put on legs through different muscle contraction type. 14 male ,14 female 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), stress hormone (Cortisol), muscle damage hormone (CK) and muscle-growth hormone (IGF-1,Testosterone). 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. The analysis of IgG between men and women showed a higher signigicant level in women isotonic squat and jump squat (p<.001). The analysis of Cortisol between men and women showed a higher signigicant level in men isotonic squat and jump squat (p<.05). The analysis of CK between men and women showed a higher signigicant level in men isotonic squat, isometricsquat and jump squat (p<.01, p<.001, p<.01). The analysis of Testosterone between men and women showed a higher signigicant level in men isotonic squat , isometricsquat and jump squat (p<.001).
