128 2018 Yearbook Strength-training Equipment for the Elderly People Professor Tzyy-Yuang Shiang Department of Athletic Performance, National Taiwan Normal University The muscle constitution of human body changes with the growing ages. And the muscle functions decline as well. In the ageing process, it is easier to see the muscles lose strength than the changing muscle constitution. The lost strength substantially reduce the muscle performance of the elderly people. Focus on the part of muscle performance, previous study indicates that the ageing condition of the old people is related to the maximum isometric contraction performance. Muscle strength is an important factor for the elderly people in their daily activity or movement performance. The declining muscle strength makes essential declination of old people’s movement. Besides, muscular explosive strength plays a key role in the muscle performance. The explosive strength makes a difference on the action and quick reflexes capability of the elderly people. Explosive strength is a more effective tool than maximummuscle strength to predict the difficulty of daily activity performances. For example, the reaction before falling down is a quick reaction movement. Reaction requires muscles to produce strength within the effective timing. The reaction is about 50-200 ms. Thus, explosive strength is an important indicator to evaluate the muscle functions. There are other documents pointing out that muscle explosive
