Background: Whole body-electromyostimulation (WB-EMS) is widely used for the rehabilitation and recovery of patients with various neuromusculoskeletal disorders. Objects: To objectively measure changes in lower extremity and abdominal muscles after sit-to-stand dynamic movement training using WB-EMS. Methods: A total of 46 healthy adults (23 experimental and 23 control subjects) performed sit-to-stand exercise; the experimental group with WB-EMS, and the control group without WB-EMS. The muscle activity of the lower extremity, and the muscle thickness of the lower extremity and abdominal muscles were measured before and after the intervention. Results: In terms of electromyographic activity, there was a significant interaction effect for the rectus femoris (RF) muscle (F=30.212, p=.000). With regards to ultrasonographic imaging, the muscle thickness of the RF muscle had a significant interaction effect at the muscle contraction ratio (F=8.071, p=.007). The deep abdominal muscles, such as the transverse abdominal (TrA) and internal oblique (IO) muscles, also showed significant interaction effects at the muscle contraction ratio (F=5.474, p=.024, F=24.151, p=.000, respectively). Conclusion: These findings suggest that WB-EMS may help to improve the muscular activity of the RF muscle, and the muscle thickness of the RF muscle and deep muscles such as the TrA and IO muscles.

이 연구는 전신 전기근자극 훈련이 비만 수준에 따른 여성의 신체조성 및 심박변이도에 미치는 영향을 분석하는 것이다. 연구 대상은 폐경 전 여성으로 BMI<25는 BMI-N(n=15), BMI=25~29.9는 BMI-1(n=16), BMI>30은 BMI-2(n=9) 집단으로 분류한 후, 12주간 주당 3회의 전신 전기근자극 훈련을 실시하였다. 실험처치 전·후 신체조성과 심박변이도를 측정하여 반복 이원 변량분석과 대응 표본 t-검정을 실시하였고, 사후검증은 Tukey의 방법을 사용하였다. 유의수준(α)은 0.5로 설정, 다음과 같은 결과를 얻었다. 첫째, Weight, BMI, FFM, FM은 BMI-2 집단이 가장 많이 감소하였고, BMI-1, BMI-N 집단 순으로 감소하였다. %BF와 VF는 BMI-2 집단이 가장 많이 감소하였다. 둘째, BPM은 모든 집단에서 차이가 나타났으며, BMI-2 집단이 가장 크게 감소하였다. SDNN과 RMSSD는 각 집단에서 차이가 나타났으며, 비만 수준에 따른 차이는 없었다. LF, HF 및 LF/HF 비율은 차이가 없었다. 결론적으로, 전신 전기근자극 훈련은 비만수준이 높은 여성들의 체구성 변화와 심장 순환계에 긍정적 효과를 미치는 운동요법이 될 수 있음을 확인하였다.

Objectives: The objective of this study was to review clinical studies conducted over the last ten years that investigated weight or fat loss interventions that can preserve muscle or fat-free mass in Sarcopenic obesity Methods: PubMed, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), Research Information Sharing Service (RISS) and Korea Studies Information Service (KISS) were searched for Randomized clinical trials that had investigated all-type of interventions on the management of sarcopenic obesity from October 2013 to September 2023. Results: A total of 14 studies met all the inclusion criteria. Interventions that increase muscle mass while reducing body fat at the same time included resistance training (including using elastic bands) and whole-body electromyostimulation(WB-EMS) in exercise intervention and Hypocaloric high-protein diet in nutritional intervention, exercise and nutritional combined intervention, and combination intervention of electrical acupuncture and amino acid supplementation. Among them, the most positive method of changing the body composition in sarcopenic obesity was the electric acupuncture and amino acid supplements. Conclusion: Varying diagnostic criteria and management interventions for sarcopenic obesity in the included studies made it hard to maintain homogeneity across the studies. Well-defined criteria for diagnostic sarcopenic obesity should be considered. In addition, since all of the interventions examined did not show sufficient clinical effectiveness, follow-up studies are needed to confirm effective interventions for sarcopenic obesity patients in the future.
