The Effect Of Exercise And Nutritional Weight Loss On The Balance Performance Of Healthy Sedentary Women

Abstract The aim of this study is to investigate the effect of weight loss, resulting from a 12-week resistance exercise and nutrition program, on 30-second static balance performance in healthy sedentary young women aged 25–35. A total of 90 sedentary women who met the inclusion criteria participated voluntarily and were randomly assigned into three groups: exercise and nutrition group (ENG), nutrition group (NG), and control group (CG). The balance performance of all participants was measured using the Tecnobody Prokin Pk 200 WL device. Subsequently, a 12-week exercise and nutrition program was applied to the ENG, only a nutrition program was administered to the NG, and no intervention was applied to the CG. After completing the 12-week programs, balance performance measurements were repeated to identify the differences. Before the study and at the end of the first six weeks, participants’ maximum strength levels were determined using the 1RM calculation method, and exercises were performed at 50% of these maximums. The analyses revealed that after the 12-week intervention, balance performance improved by 37.6% in the ENG and by 16.0% in the NG. The balance performance improvement in the ENG was found to be 21.6% higher compared to the NG. In conclusion, the combination of an exercise program supported by a nutrition plan has a more significant effect on balance performance than a nutrition program alone. These findings suggest that such interventions can positively impact daily life and improve the quality of life in sedentary women.
