Brief summary
The latest randomized controlled trials and systematic reviews of resistance training performed by older adults reported that the systematic use of exercise in machines improves muscle strength and power, functional abilities, body mass and body balance. However, the effect of resistance training with elastic tubes exercises have not been studied in all the variables described above. The objective of this study is to analyze the effects of elastic tubes exercises on muscle mass, muscle strength, functional performance and postural control in elderly untrained.
Detailed description
This is a randomized clinical trial study (RCT) with 2 parallel arms. The subjects will be divided in 2 groups with a randomized block technique: Elastic Training Group (ETG) and Machine Training Group (MTG). The subjects will be submitted to a two-week familiarization period and then a sixteen-week of strength training program will be performed twice a week. This regimen of resistance training in both groups will consist of four exercises for lower limbs and four exercises for upper limbs which will be alternately performed with a one-minute interval between them during familiarization and training periods. Lower limb exercises will consist of: hip extension and abduction, and knee flexion and extension. Upper limb exercises will consist of: bench press, rowing, triceps and high pulley exercise.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in Body Mass | Change from baseline in body mass at 16 weeks. | To assess muscle mass, a Dual-energy X-ray Absortiometry (DXA) (GE Electric Company®, Lunar Prodigy) will be used. |
| Change in Muscle Strength | Change from baseline in muscle strength at 16 weeks. | Lower limb muscle strength will be assessed with an isokinetic dynamometer (Biodex System®, model III) and upper limb muscle strength with an isometric dynamometer (Jamar®, Hand Dynamometer). |
| Change in Postural Balance | Change from baseline in postural balance at 16 weeks. | The postural balance will be assessed with a three-dimensional (3D) motion analysis system and force plates. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in Functional performance | Before and after 16 weeks of resistance training | The functional performance will be assessed with Ten Meters Walk Test (TMW), Timed Up&Go Test (TUG) and 30 Second Chair Stand Test (T30). |
