Document Summary
Age diferences in knee extension power, contracile velocity and faigue. Examine age and gender diferences i knee extensor strength, power and faigue in open and closed tesing procedures. Hypothesis: speciic strength would not difer by age, age diferences in speciic power and faigue would remain consequent to maximal contracile velocity. 28 young and 24 older men and women, including irm (knee ext, leg press, squat) Thin lean mass was assessed by dual-energy x-ray. Sarcopenia leads to accelerated reducions in muscle mass and strength beyond 5 th decade (1- 2% per year), primary task for dependence and disability in elders. Age related decline in muscle power are at a greater rate (3-4%) than strength: important for mobility and ambulaion, walking, stairs, increased falls. Decline in power may be due to loss of max velocity. 52 adults, 2 age groups (60-75 13 men, 11 women) and (20-35 12 men, 16 women)
