The Effect of Eight Weeks of Anaerobic Interval Training on the Body Composition Indices of Inactive Obese Women

In recent years, the prevalence of obesity and overweight among untrained men and women has grown significantly and has now become a serious problem in the world. The aim of this study was to evaluate the effect of eight weeks of anaerobic interval training on body composition indices in inactive obese women.

As an applied research, the present quasi-experimental study with pre-test and post-test design was conducted with two groups of anaerobic interval training and control, in which data were collected through a field study. The statistical sample of the study included 24 obese women over 40 years of age who were assigned into two groups including anaerobic interval training group and control group. Anaerobic interval training was performed for 8 weeks, 5 sessions per week and 25 minutes per session. Before the start of the study and 48 hours after the last training session, body fat percentage, body fat mass, lean body mass and body mass index were measured. Statistical analysis of the findings was performed using independent and dependent samples t-test at a significance level of P <0.05.

Eight weeks of anaerobic interval training has a significant effect on reducing body fat percentage and body mass index as well as increasing lean body mass (P≥0.05).

It seems that eight weeks of anaerobic interval training improves the body composition of inactive obese women.
