Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Aging Other: Strength training program Not Applicable

Detailed Description:

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

  1. 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.
  2. 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.

Arm Intervention/treatment
Experimental: Group A
group of elderly participants of strength training program
Other: 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.


No Intervention: Group B
group of seniors who did not practice strength training program



Primary Outcome Measures :
  1. Change in elderlies's microcirculatory blood flow after 4 months [ Time Frame: 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).

  2. Change in elderlies's muscle fatigue after 4 months [ Time Frame: 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.

  3. Change in elderlies's functional capacity after 4 months [ Time Frame: 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


Secondary Outcome Measures :
  1. Change in elderlies's strength after 4 months [ Time Frame: 4 months ]
    The lower body strength of the elderly will be measured by 30-s chair test stand after 4 months.

  2. Change in elderlies's functional autonomy after 4 months [ Time Frame: 4 months ]
    The functional autonomy of the elderly will be determined by the general functionality index of the Latin American Development Group to Maturity Protocol after 4 months.
