Overview
Brief Summary
Sarcopenia leads to loss of muscle mass and muscle strength during the aging process. It has been reported that eccentric training has some positive effects on the preservation of eccentric strength, with less delayed onset muscle soreness (DOMS) in older groups, and lower metabolic costs.
Detailed Description
This is prospective study. The goals of this study are to: 1. Examine the effects of eccentric training on physical function (gait speed, stair climb, chair stand) in older adults. 2. Examine the effects of eccentric training on muscle strength (Isometric strength, Isokinetic strength, power) in older adults.

Outcomes
Primary Outcomes
Gait speed
Time Frame: Change from baseline gaitspeed at 8 weeks
An examiner used a stopwatch to time how long it took subjects to walk along a marked tape. The Kinect device was used to measure gait speed.
Stair climb
Time Frame: Change from baseline stair climb at 8 weeks
Subjects were measured on eight 17-cm stairs twice, requiring a step by step pattern, where the timer activated when the first contact was made at the first step and ended when the contact occurred at the last step before and after the 8 weeks of exercise training.
Chair stand
Time Frame: Change from baseline chair stand at 8 weeks
Subjects had to get up from a chair measuring 41 cm in height with a flat seat. Subjects were asked to stand up and sit down 5 times as quickly as possible with their arms folded across the chest. They stood up until full extension was observed at the trunk and lower limb joints, and returned to a seated position with their back fully supported at the back of the chair.
Secondary Outcomes
- Isokinetic knee strength(Change from baseline isokinetic knee strength at 8 weeks)
- Isometric knee strength(Change from baseline isometric knee strength at 8 weeks)
- Power(Change from baseline power at 8 weeks)
