Description détaillée
Purpose
The primary research question is:
Do muscular strength training programs can improve functional capacity, muscle performance and microcirculation in the elderly? Hypothesis: Strength training program will promote electromyographic changes during the development of peripheral muscle fatigue and microcirculatory blood flow contributing to functional autonomy.
Secondary Research Questions
- Does the strength training program in the elderly improve the standard of electromyographic fatigue? Hypothesis: Elderly practitioners of strength exercise program showed increased neuromuscular efficiency and electromyographic fatigue index.
- Do the strength training program in the elderly improve peripheral microcirculation? Hypothesis: A regular program of strength exercise in the elderly increases the blood flow in peripheral microcirculation changing the process of muscle fatigue. These biomechanical and physiological changes contribute to increased functional autonomy and reducing the risk of falls in the elderly.

Description de la mesure |
Délai |
|---|---|---|
|
Change in elderlies's microcirculatory blood flow after 4 months
Délai: 4 months
|
The blood flow in the microcirculation in the elderly will be measured by laser-doppler flowmetry.
The measures blood flow in the microcirculation will be quantified by the reactive hyperemia Post-occlusion protocol (PORH).

|
Change in elderlies's muscle fatigue after 4 months
Délai: 4 months
|
muscle fatigue will be quantified by surface electromyography of the muscles of the lower limbs.
The electromyographic fatigue threshold and fatigue index will be calculated by the Root Mean Square (RMS) and Median Frequency variables after 4 months.

|
Change in elderlies's functional capacity after 4 months
Délai: 4 months
|
The functional capacity of the elderly will be evaluated by the Berg Balance Scale, the Timed up-and-go Test, and Falls Efficacy Scale International (FES-I) after 4 months
