Effects of progressive interval training program on body mass index, body composition and maximum oxygen consumption of overweight/ Obese female college Students
Abstract:
Objectives: The purpose of this study was to study the effects of progressive interval
training program on body mass index, body composition and maximum oxygen consumption of
overweight/ obese female college students. The fifteen overweight/ obese female aged 18-23
years. The experimental group received progressive interval training program at 70-80 percent of
MHR (3 min intervals at 70-80 percent of maximal heart rate, each interval separated by 3 min at
50 percent, 40-60 min per session, 3 day a week for 8 weeks). The variables collection were body
mass index, body composition (percent fat, fat mass, fat free mass), and maximum oxygen
consumption. Assessments completed at baseline, 4, 6, and 8 weeks. Repeated-measures ANOVA
were used data analysis. Significant level was set at .05.
Results: After 8 weeks of progressive interval training program, body mass index was
no significant difference between 4 and 6 weeks, but in 8 weeks was significant decreased in
body mass index (p = .041), percent fat and fat mass, was no significant difference between 4 and
6 weeks, but in 8 weeks mean difference significant (p = .041 and p = .029) and fat free mass
were no significant difference between 4, 6 and 8 weeks. And maximum oxygen consumption
after the 4 weeks was no significant difference, but in 6 weeks and 8 weeks (p = .015 and p =
.005) increased significant. The satisfaction in the use of a training program was in the high level
(X = 4.12, SD = 0.48).
Conclusion: The progressive interval training program can increase maximum oxygen
consumption, reduce percent fat, fat mass and body mass index of overweight/ obese subjects.
