Abstract
Abstract:
Background: Resistance training improves muscle quality (such as muscle mass and strength). Considering that one of the major problems of the elderly is the reduction of muscle mass and strength, which is called sarcopenia; The purpose of this study is to investigate the effect of 8 weeks of High Intensity Interval Resistance Training (HIIRT) on the body composition of older women.
Methods: 30 older women (average age of 65.96±2.98, height 155.66±5.16 and weight 67.20±7.31) were participated in the present study and were randomly assigned to two experimental groups (EX:15 people) and Control (C:15 people). The EX group were participated in HIIRT protocol with an intensity of 50-85% of 1RM for 8 weeks/3 sessions per week, but the C group did not participate in any type of training program and only did their normal daily activities. Body mass index (BMI), body fat percentage, appendicular muscle mass were measured at week 0 and at the end of week 8. Statistical analysis of the data was done with independent t-test and within group one-way analysis of variance using spss version 23 statistical software at a significance level of 0.05.
Results: The results showed that body composition (weight: p=0.004; fat-free mass: p=0.0001; body fat percentage: p=0.001; muscle mass: 0.0001) of the EX group improved significantly compared to the C group.
Conclusion: Therefore, according to the results, High-Intensity Interval Resistance Training improves body composition, especially the muscle mass of older women, and is a non-invasive method for improving sarcopenia, and there are no restrictions for the participation of older people, under the care and supervision of educated sports science trainers
