Brief summary
The study investigates the acute psychological effects of a whole-body-workout using Electromyostimulation (EMS) in participants with depression and healthy individuals.
Detailed description
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 acute psychological effects of an EMS workout - especially with regard to the reduction of depressive symptoms. Physical activity is notably important for patients with depression and shows multiple positive psychological and physical effects. But due to disease-related factors like lethargy, physical activity is far too rarely implemented. Therefore EMS-whole-body-workouts could provide an opportunity to generate positive psychological effects through a less (subjective) cost-intense strength training.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in depressive symptoms | From directly before the intervention to immediately after the intervention - both: before/after the EMS-training-session and before/after the Placebo-session | Depressive symptoms are measured using the State-Scale of the State-Trait Depression Scales (STDS) by Spaderna, Schmukle & Krohne (2002). The SDTS State-Scale has two subscales with each 5 likert scaled items with values ranging from 1 to 4. Higher scores mean a worse outcome for the first subscale and a better outcome for the second subscale. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in anxiety symptoms | From directly before the intervention to immediately after the intervention - both: before/after the EMS-training-session and before/after the Placebo-session | Anxiety symptoms are measured using the the State-Scale of the State-Trait Anxiety Inventory (STAI) by Laux, Glanzmann, Schaffner & Spielberger (1981). The STAI State-Scale has 20 likert scaled items with values ranging from 1 to 4, higher scores mean a worse outcome. |
| Change in general self-efficacy | From directly before the intervention to immediately after the intervention - both: before/after the EMS-training-session and before/after the Placebo-session | General self-efficacy is measured using the General-Self-Efficacy Scale (GSE) by Jerusalem & Schwarzer (1981). The GSE has 10 likert scaled items with values ranging from 1 to 4, higher scores mean a better outcome. |
| Change in intention for physical activity | From directly before the intervention to immediately after the intervention - both: before/after the EMS-training-session and before/after the Placebo-session | Intention for physical activity is measured using two likert scaled items by Petzold et al. (2017). Values ranging from 1 to 4, higher scores mean a better outcome. |
| Change in self-efficacy regarding physical activity | From directly before the intervention to immediately after the intervention - both: before/after the EMS-training-session and before/after the Placebo-session | Self-efficacy is measured using two likert scaled items by Petzold et al. (2017). Values ranging from 1 to 4, higher scores mean a better outcome. |
