---|---|---|---|---|
Primary | Self-selected walking speed - SSWS | This outcome will be measure through sub-maximal test of walking treadmill, using the portable gas analyser Equipment. | Change from baseline SSWS at 8 weeks | |
Secondary | Quality of life (QoL) | The quality of life will be estimated using the World Health Organization Quality of Life Project for elderly people (WHOQOL) instrument. | Change from baseline QoL at 8 weeks | |
Secondary | Locomotor rehabilitation index (LRI) | This outcome will be measure through of the measure on sub-maximal test of walking treadmill, using the three-dimensional motion analysis system (VICON). | Change from baseline LRI at 8 weeks | |
Secondary | Oxygen consumption (VO2) | This outcome will be measure through of the of the walking test on treadmill and too using the portable gas analyzer equipment (units in ml/kg/min). | from baseline to 8 weeks | |
Secondary | Cost of transport (C) | This outcome will be measured through of the walking test on a treadmill will be collected the oxigem consumption using the portable gas analyzer equipment (measure unit in ml.O2.km). | from baseline to 8 weeks | |
Secondary | Optimal Walking Speed (OPT) | This outcome will be measure through of the registered image movement analysis using the three-dimensional motion analysis system (VICON) of the walking test on treadmill (unit in km/h) | from baseline to 8 weeks | |
Secondary | Oxygen Consumption at anaerobic threshold (VO2VT2) | This outcome will be measure through maximal progressive treadmill test, using the portable gas analyser VO2000 equipment. | from baseline to 8 weeks | |
Secondary | Peak Oxygen Consumption (VO2peak) | This outcome will be measure through maximal progressive treadmill test, using the portable gas analyser VO2000 equipment. | from baseline to 8 weeks | |
Secondary | Heart Rate at anaerobic threshold (HRVT2) | This outcome will be measure through maximal progressive treadmill test, using a heart rate monitor (POLAR, FT1). | from baseline to 8 weeks | |
Secondary | Rest Heart Rate (HRrest) | This outcome will be measure using a heart rate monitor (POLAR, FT1). The participants will remain seated in a quiet and controlled temperature room during 15 minutes prior to measurement of the heart rate. | from baseline to 8 weeks | |
Secondary | Exercise Heart Rate (HRexercise) | This outcome will be measure using a heart rate monitor (POLAR, FT1) measurement of the heart rate of exercise during the walking test on treadmill at different speed. | from baseline to 8 weeks | |
