Strength Training for Elderlies and Their Effects on Muscle Fatigue and Microcirculation - Randomized Clinical Trial
2016年8月11日 更新者：João Guilherme Bezerra Alves、Professor Fernando Figueira Integral Medicine Institute
The purpose of this study is to verify the effects of a strength training program on functional capacity, muscle performance and microcirculation in the elderly.

详细说明
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.

实验性的：Group A
group of elderly participants of strength training program
|
Strength Training program applied twice a week for sixteen weeks. Each training exercises has a total time of 50 minutes. Warm-up: 5 minutes of stretching. Training: Leg press; Leg Curl; Vertical traction; Chest press; Abdominal crunch; Lower back. Gametherapy. Relaxation: 5 minutes of stretching. |

Change in elderlies's microcirculatory blood flow after 4 months
大体时间：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
大体时间：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
大体时间：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
