Different Isometic Muscle Strength Testing Evalue The Middle-Old People's Strength Quality Feasibility Study

Object:China is the most populous and elder population rapidly growing country. Since 1980, in our country the aged above 60 elderly population continued Aged above 60 increase at an average speed of 3.0% annually. At present, in our country, elderly population have reached 1.74 billion, accounting for one fifth of the world's elderly population. until 2025 the elderly population factor in China will reach 20%, become the super old people country. In the increasing elderly population country, the elderly health problems gradually become the focus of the society. With the increase of age, the function of each organ system gradually recession, including muscle strength decline rapidly which will bring more serious consequences. The elderly in China especially the old people tend to ignore strength exercises, case the recession of Muscle strength is more apparent, action ability received great restraint, seriously affected the old people's health and quality of life. This article through to Muscle strength testing of 40 to 69 old people will receive 14 Muscle strength index factor analysis of systemic.Extracting the most representative index which can represent the body physique health as body strength index.Subject and methodsThe study recruite 191 healthy persons aged at 20-39y as the subjects. Physical fitness, body composition,body function and bone fitness were tested. To explore the characteristic of isometric strength of different body parts and their correlation of physical fitness and health, including physical fitness, body composition and bone fitness. All parts of isometric strength was calculated by faceor analysis, in order to screen the assessment index of whole body strengths.Conclusion 1. for the middle-aged men, Muscle strength of extend hip, Torso lateral flexion, hip outreach and shoulder outreach are the most representative and have close relations with physical health. Therefore, the four Muscle strength index can serve as systemic muscle strength representative index.2. For middle-aged and older women, Muscle strength of hip outreach the trunk lateral flexion and shoulder outreach are the most representative and have close relations with physical health. Therefore, the four Muscle strength index can serve as systemic muscle strength representative index.
