简要总结
The study investigates the midterm, longterm and acute psychological and physical effects of an 8-week whole-body-workout using Electromyostimulation (EMS) in healthy individuals.
详细描述
EMS-whole-body-workouts are less time-consuming and effort-intensive but generate physical effects which are comparable to conventional strength training. Therefore EMS could lower the barrier to physical activity. The present study focusses on psychological and physical effects of an 8-week EMS workout. Physical activity is notably important for mental and physical health, but is on average far too rarely implemented. Therefore EMS-whole-body-workouts could provide an opportunity to generate positive psychological and physical effects through a less (subjective) cost-intense strength training.

研究组 & 干预措施
Experimental-Condition
8 weeks x weekly 20 minutes whole-body-workouts with simultaneous muscle stimulation (EMS).
Participants carry out easy whole-body-exercises while wearing a EMS-vest-belt-system with interwoven electrodes. During the workout the muscles are simultaneously stimulated by those external electrodes with medium level (5) of stimulation intensity.
干预措施: Electromyostimulation Whole-Body-Workout (Device)
Sham-Condition
8 weeks x weekly 20 minutes whole-body-workouts without simultaneous muscle stimulation (EMS).
Participants carry out easy whole-body-exercises while wearing a EMS-vest-belt-system with interwoven electrodes. During the workout the muscles are not actually stimulated by EMS.
干预措施: Electromyostimulation Sham Whole-Body-Workout (Device)
结局指标
主要结局
Acute change of subjective well-being.
时间窗: From directly before each of the eight training sessions do directly after each of the sessions (EMS-Training/Sham) during the 8 weeks of training.
• Subjective well-being is measured using a visual analogue scale (0-100%, higher value = better outcome).
Acute change of subjective relaxation.
时间窗: From directly before each of the eight training sessions do directly after each of the sessions (EMS-Training/Sham) during the 8 weeks of training.
• Subjective relaxation is measured using a visual analogue scale (0-100%, higher value = better outcome).
Change of acute symptoms of anxiety and depression.
时间窗: From directly before each of the eight training sessions do directly after each of the sessions (EMS-Training/Sham) during the 8 weeks of training.
• The State-Scale of the State-Trait-Anxiety-Depression-Inventar (STADI-State; Renner, Hock, Bergner-Köther \& Laux, 2018) is used to assess acute symptoms of depression and anxiety. The raw score ranges from 10 to 40, higher values indicate a worse outcome.
次要结局
- Change in general self-efficacy(Baseline (before any training) + Intermediate (4 weeks) + Post (8 weeks) + Follow-Up (12 weeks).)
- Change in physical parameters: heart rate variability.(Baseline (before any training) + Intermediate (4 weeks) + Post (8 weeks) + Follow-Up (12 weeks).)
- Change in attitudes regarding physical activity (intentions for physical activity, self-efficacy regarding physical activity)(Baseline (before any training) + Intermediate (4 weeks) + Post (8 weeks) + Follow-Up (12 weeks).)
- Mid-/longterm changes in depressive symptoms.(Baseline (before any training) + Intermediate (4 weeks) + Post (8 weeks) + Follow-Up (12 weeks).)
- Mid-/longterm changes in anxiety symptoms.(Baseline (before any training) + Intermediate (4 weeks) + Post (8 weeks) + Follow-Up (12 weeks).)
- Mid-/longterm changes in affect-related psychological variables.(Baseline (before any training) + Intermediate (4 weeks) + Post (8 weeks) + Follow-Up (12 weeks).)
- Mid-/longterm changes in positive and negative affect.(Baseline (before any training) + Intermediate (4 weeks) + Post (8 weeks) + Follow-Up (12 weeks).)
- Change in physical parameters: hand force.(Baseline (before any training) + Intermediate (4 weeks) + Post (8 weeks) + Follow-Up (12 weeks).)
- Change in physical parameters: leg strength.(Baseline (before any training) + Intermediate (4 weeks) + Post (8 weeks) + Follow-Up (12 weeks).)
