Active Comparator: High-speed power training
Volunteers randomized into SHPT will be exercised 3 times per week for 12 weeks. Each training session will consist of 3 sets of 12 to 14 repetitions at 40% of maximal strength for leg press (LP) and seated knee extension (KE) exercises.
Other: High-speed power training
exercised 3 times per week for 12 weeks. Each training session will consist of 3 sets of 12 to 14 repetitions at 40% of maximal strength
Other Name: weight training
Active Comparator: Slow-speed strength training
Volunteers randomized into STR will be exercised 3 times per week for 12 weeks. Each training session will consist of 3 sets of 8 to 10 repetitions at 80% of maximal strength for LP and KE exercises.
Other: Slow-speed strength training
exercised 3 times per week for 12 weeks. Each training session will consist of 3 sets of 8 to 10 repetitions at 80% of maximal strength
Other Name: weight training
No Intervention: Control
Volunteers randomized into CON will undergo a placebo exercise intervention consisting of lower extremity range of motion and flexibility exercises performed 2 times per week with the assistance of the research staff.
- Strength and power [ Time Frame: 3 months ]The strength of the lower limb muscles will be measures using Keiser pneumatic leg press and knee extension exercise machines. The Keiser machines allow for the specific measurement of the contributions of force and velocity to the development of power, which will reveal whether the high-speed training protocol impacts speed-related measures of muscle performance.
- Function [ Time Frame: 3 months ]Measures of mobility and function were evaluated using the 400-m Walk, Berg Balance Scale and timed chair rise which assess walking endurance, balance, and strength, respectively, all important variables for mobility
