Active Comparator
High Velocity Exercise
Low Velocity exercise
The high velocity exercise group performed the concentric contraction phase of resisted exercise in one second or less. This group performed sit to stand exercise, walking, curbs, and stairs as fast as was comfortable without an increased limp. Other exercises were performed at the participant preferred rate.
The low velocity exercise group performed the concentric contraction phase of resisted exercise in two seconds. This group performed sit to stand exercise, walking, curbs, stairs, and other exercises at the participant preferred rate.
