To analyze the influence of time under physical exercise practice on the body composition of women.

Methods:

A quasi-experimental study with ex post facto design. Thesample was composed by 61 women, aged above 40, participants of an exercise program sponsored byEducation Program through Work for Health (PET-Saúde) at the Universityof Fortaleza, being divided into two groups Group 1 - Case (had been practicing exercise for at least 6 months) and Group 2 - Control (had been practicing exercise for less than6 months). Measures of weight, height, body mass index, waist and hip circumferences, and body composition (bioelectrical impedance model 310) were evaluated. For health parameters, the Canadian Standardized Test of Fitness was used. The statistical treatment was performed using descriptive analysis (mean and standard deviation) and inferentialapproach (Independent-Sample T and One-Sample T Test). The level of significance was p <0.05.

Results:

No significant difference (p=0.48) was found for the BMI variable betweenCase Group (28±4 kg/m2) and Control Group (27.5±4.2 kg/m2). Both groups presented proper standards of health. For the results on waist-hip ratio, it was not found significant difference (p=1.10) between the groups, however, there was significant differences in each group when compared to health standards. The percentage of fat was not different (p=0.56) between the groups, but when this variable was related to health standards, a significant difference was observed in both groups.

Conclusion:

Regarding the anthropometric variables, no influence of time was observed on body composition, neither on the health standards. The absence of significant difference between the groups is probably related to the maintenance of body mass and lean body mass, suggesting changes in the frequency and volume of the exercise program, inorder to provide significant changes in the body composition...
