Abstract: (581 Views)
Background and Objectives: Muscle weakness is one of the side effects of inactivity that causes movement disorders and skeletal muscle abnormalities, especially in teenage girls. Therefore, resistance sports stimulate and grow muscles, maintain stability and balance in the body. This study was conducted with the aim of determining the effect of resistance exercise on the muscle strength of female students aged 13-15 years in Gorgan city.
Materials and Methods: This experimental study was conducted on 50 female students aged 13-15 years old in Gorgan city as a simple random allocation in two groups of test and control. In the test group, 8 training sessions were performed every week, 2 sessions of 50-60 minutes in the gym. No intervention was performed in the control group. The tools for measuring upper and lower body muscle strength were chest press weight and leg weights respectively. The data was entered into SPSS21 statistical software and analyzed by descriptive statistics and inferential statistics.
Results: Covariance test showed a significant difference in comparing upper body muscle strength with eliminating the effect of pretest (P <0.01, Eta = 0.28). Covariance test showed a significant difference in comparing lower torso muscle strength by eliminating the effect of pretest (P <0.01, Eta = 0.42).
Conclusion: Resistance exercise plays an important role in strengthening the muscular strength of the upper and lower limbs of students. It is necessary for managers and health professionals to use these training methods to prevent girls' spine problems.
