| Abstract |
Normal weight obesity (NWO) is a new definition of obesity that in which a person's body mass index (BMI) is normal (< 25) but percentage of body fat (%BF) exceeds 30%. Middle-aged women show a high prevalence of obesity with age until sarcopenia occurs. Thus, this study selected 13 middle-aged women (39 ± 3 yr) and divided them into two groups (NWO: n=6; Normal: n=7) based on %BF to investigate the effects of 8 weeks twisting training on physique, body composition, isokinetic strength, and physical fitness. Both groups participated in the same twisting training program 3 times per week. The objective of this study is examining the effect of twist training that stimulates mainly on lower body, storing a large fat proportion in middle-aged women. According to the results found in this study, the NWO group had significant improvement of waist circumference (WC), waist-hip ratio (WHR), muscle strength in flexion, extension of trunk, leg flexion, and muscle endurance in leg extension (p<.05). However, there is no significant difference in other variables. In conclusion, twisting training had a positive effect on WC, WHR, and isokinetic strength, while no benefits were found in body composition and physical fitness. |
