Strength Training and Quality of Life in Elderly

Study Overview
=================
Brief Summary
-----------------
Aim: To evaluate the impact of three different strength training programs on psychological wellbeing of elderly.

Detailed Description
-----------------
Background: Physical activity in the elderly has benefits which improve psychological wellbeing. However, the majority of older adults perform less physical activity with advancing age. Aim: To evaluate the impact of three different 32-week strength training programs (low, moderate and high intensity) on psychological wellbeing of elderly. Design: Randomized Controlled Trial.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Quality of life, assessed through the Short Form 36 health survey questionnaire. | This questionnaire measures quality of live. It provides information on 8 scales, scoring from 0 (worst health) to 100 (best health), and on the physical component scale (PCS) and the mental component scale (MCS), normalized scores representing overall physical and mental functioning. | 32 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Emotional wellbeing, assessed through the STAI (State-Trait Anxiety Inventory) questionnaire. | The State-Trait Anxiety Inventory (STAI) is a commonly used measure of trait and state anxiety (Spielberger, Gorsuch, Lushene, Vagg, & Jacobs, 1983). It can be used in clinical settings to diagnose anxiety and to distinguish it from depressive syndromes. It also is often used in research as an indicator of caregiver distress. STAI has 20 items for assessing trait anxiety and 20 for state anxiety. All items are rated on a 4-point scale (e.g., from Almost Never to Almost Always). Higher scores indicate greater anxiety. | 32 weeks | 
| Motivation towards physical activity, assessed through the Behavioural Regulation in Exercise Questionnaire (BREQ-2) | This questionnaire consists of 19 items measuring stages on the continuum of self-determination. It measures external regulation (4 items), introjected regulation (3 items), identified regulation (4 items), intrinsic regulation (4 items), and it adds amotivation (4 items) on a scale from 1 (Not at all true for me) to 5 (Absolutely true for me). Each of the subscales has a maximum score, with a maximum of 20 for external regulation, identified regulation, intrinsic regulation and amotivation, and 15 for introjected regulation. | 32 weeks |
