Losing weight at female recreationists with body building.

Abstract

The research was conducted on a sample consisted of 10 female recreationists 20 to 30 years old, who wanted to lose weight and to decrease the percent of fat mass. In order to follow the changes in body composition four variables were measured: body mass (BM), percent of body fat (%BF), water percent (%W) and percent of muscle tissue (%MT). In order to see the time when the changes appear, the subject were measured 3 times - first time before the start of the exploration (initial measurement), at the end of the second month (control measurement) and at the end of the forth month (final measurement). The group was exercising 1 ½ hours, 5 times a week, mostly in the morning. In order to estimate the differences between initial and control, between control and final, and between initial and final measurement, T – test of small dependent samples was applied. From the obtained results it can be concluded that at the end, the final goal was achieved, decrease in both, body mass (BM) and percent of body fat (%BF).
