Clinical Trial 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.

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in elderlies's microcirculatory blood flow after 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).	4 months	No
Primary	Change in elderlies's muscle fatigue after 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.	4 months	No
Primary	Change in elderlies's functional capacity after 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	4 months	No
Secondary	Change in elderlies's strength after 4 months	The lower body strength of the elderly will be measured by 30-s chair test stand after 4 months.	4 months	No
Secondary	Change in elderlies's functional autonomy after 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.	4 months	No
