Effects of Continuous and Intermittent Aerobic Exercise on Body Composition, Cardiorespiratory Fitness and Immunoglobulin in the Middle-aged Women

The purpose of this study was to analyze the effects of intermttient and continuous aerobic exercise onbody composition, cardiorespiratory fitness and immunoglobulin in the middle-aged women. The subjectswere 21 middle-aged women. They were divided into two groups: ocntinuous aerobic training group (CAT , n=11) and intermittent aerobic training group (IAT, n=10). The exercise program consists of 40-60%HRR, 60min/day, 3 days/week for 12 weeks. Body composition, cardiorespiratory fitness, immunoglobulin levels weremeasured in all subjects at week-0, week-4, week-8, and week-12. All data were analyzed by Two-wayrepeated measures ANOVA and One-way ANOVA using SPSS version 2.10. These results indicate that co-ntinuous aerobic exercise has more beneficial effect on improvements in cardiorespiratory fitness compared tointermittent aerobic exercise, while no beneficial effects on changes in body composition and immunoglobulinthan intermittent aerobic exercise. This suggests that about 4w eeks of detraining does not result in advers eeffects on metabolic and immune function in apparently healthym iddle-aged woman if about 4 weeks of r-etraining follows.
