چکیده مقاله انگلیسی:

اثرات تحریک الکترومیوتیسم کل بدن بر کاهش توده عضلانی ناشی از محدودیت انرژی در طول کاهش وزن مورد نظر

Purpose: Overweight and obesity are an increasing problem worldwide. However, most studies that focus on weight reduction by energy restriction and/or aerobic exercise reported considerable loss of muscle mass as well. Increased protein intake and/or resistance exercise might inhibit this detrimental effect during a negative energy balance. Whole-body electromyostimulation (WB-EMS), a time effective, joint-friendly, and highly customizable training technology, showed similar hypertrophic effects compared with high-intensity resistance training. The aim of this study is to evaluate the effect of WB-EMS on body composition during negative energy balance with maintained/increased protein
intake in overweight premenopausal women

Patients and Methods: Ninety premenopausal, 25–۵۰-year-old, overweight women were randomly assigned to three groups (n = 30 each). (1) Negative energy balance by energy restriction with compensatory protein intake. (2) Negative energy balance (−۵۰۰ kcal/day) by energy restriction (−۲۵۰ kcal/day) and increased physical activity (−۲۵۰ kcal/day) with increased protein intake (PA). (3) Negative energy balance due to energy restriction and increased physical activity with increased protein intake plus WB-EMS. The duration of the intervention was 16 weeks. Participants underwent restrictions in kcal per days and supplementation of protein where needed. Bipolar WB-EMS was applied 1.5× week for 20 min. The primary study endpoint “lean body mass” (LBM) and secondary endpoint body fat mass (BFM) were assessed by bio-impedance analysis (BIA)

:Results

 LBM decreased in the CG and PA group but increased in the WB-EMS group. However, changes were not significant (p > 0.05). Comparing the groups by ANOVA, no significant differences were observed (p = 0.070). However, pairwise adjusted comparisons determined significant differences between WB-EMS and PA (p = 0.049). BFM decreased significantly ( p < 0.001) in all groups without any significant difference between the groups

(ANOVA: p = 0.131). Conclusion: WB-EMS is an efficient, joint-friendly, and highly customizable training technology for maintaining muscle mass during energy restriction and can thus be considered as an alternative to more demanding resistance exercise protocols
