The purpose of this study was to investigate the effects of power walking program on the immune response including interleukin-6(IL-6), tumor necrosis factor-α(TNF-α), c-reactive protein(CRP), white blood cell(WBC) in female adults.
31 healthy female adults aged 19 to 22 years were participated in this study and classified as a three groups by light walking group(30-60 HRmax, 3-5d/wk, 30-55min/d), power walking group(40-70 HRmax, 3-5d/wk, 30-55min/d), control group(non exercise program). They performed power walking program on treadmill for 12 months. Interleukin-6(IL-6), tumor necrosis factor-α(TNF-α), c-reactive protein(CRP), white blood cell were measured before treatment, after 6 months, and 12 months of program treatment. Cardiorespiratory fitness were indirectly assessed by Haevard 5-minute step test. Repeated Measured Analysis of Variance(ANOVA), Multiple Range Test(Bonferroni), Analysis of Pearson Product-Moment Correlation, Analysis of Simple Linear Regression, and Dubin Watson Test were used to examine the statistical significance using SPSS 12.0 windows(SPSS Inc., Chicago, Illinois). There were significant differences on TNF-α for 12 months among three groups and walking period(p<.05), but there were no significant differences on IL-6, CRP, and WBC among three groups. Cardiorespiratory fitness was associated with IL-6(r=0.39, p<.05).
In conclusion, power walking for 12 months may be partly affected on immune response in healthy female adults.
