- Brief Summary
Abstract: Background and Objectives: This study investigated the various impulse-effects of whole body-electromyostimulation (WB-EMS) on psychophysiological responses and adaptations. Materials and Methods: The participants included fifty-four men between 20 and 27 years of age who practiced isometric exercises for 20 min, 3 days a week, for 12 weeks while wearing WB-EMS suits, which enabled the simultaneous activation of 8 muscle groups with three types of impulse intensities. Participants were allocated to one of four groups: control group (CON), low im-pulse-intensity group (LIG), mid impulse-intensity group (MIG), and high impulse-intensity group (HIG). Psychophysiological conditions were measured at Week 0, Week 4, Week 8, and Week 12. Results: Compared with CON, 1) three psychological conditions in LIG, MIG, and HIG showed positive tendencies every four weeks and the ANCOVA test revealed that body image (p = 0.004), body shape (p = 0.007), and self-esteem (p = 0.001) were significantly different among groups. 2) Body weight, fat mass, body mass index, and percent fat in CON showed decreasing tendencies, whereas those in LIG, MIG, and HIG showed a noticeable decrease, which revealed that there were significant differences among groups. Specifically, higher impulse intensity re-sulted in greater increase in muscle mass. 3) Although there was no interaction effect in the ab-dominal visceral fat area, there were significant interactions in the abdominal subcutaneous fat (ASF) and total fat (ATF) areas. Both ASF and ATF in CON showed decreasing tendencies, whereas those in other groups showed a noticeable decrease. The ANCOVA revealed that ASF (p = 0.002) and ATF (p = 0.001) were significantly different among groups. In particular, the higher the impulse intensity, the greater the decrease in abdominal fat. Conclusion: This study confirmed that high impulse-intensity EMS can improve psychophysiological conditions. In other words, healthy young adults felt that the extent to which their body image, body shape, and self-esteem improved depended on how intense their EMS impulse intensities were. The results also showed that higher levels of impulse intensity led to improved physical conditions.

- Completed
- Sex
- Male
- Target Recruitment
- 54
The participants were aged between 20 and 27 years old. All volunteers wanted to improve their body shape and were checked by a bioelectrical impedance analysis (BIA) device. This study recruited healthy male college students who lived in a dormitory and did not exercise regularly for a duration of six months.
They were excluded if they had received any treatment for weight loss, taken any medication known to affect body composition, or had undergone any major surgery during the one year prior to the start of the study. The following were also reasons for exclusion: having a history of coronary arterial disease, severe cerebral trauma, cerebrovascular disease, pulmonary disease, uncontrolled hypertension, cancer, and psychiatric diseases, such as eating disorders.
