Background: After Taiwan entered the aging society in 1993, the 2018 elderly population has officially entered 14% of the old age society, facing the problems brought about by aging. As the age increases, the functions of multiple physiological systems will gradually Recession causes many physical function characterizations to decline and poor health outcomes, and psychological changes reduce the ability of the environment to adapt, or cause negative effects on quality of life. The impact of exercise on the cognitive function of the elderly is one of the hot topics today. The function of exercise for the cognitive function of the elderly is more significant in performing functions than other cognitive components. In particular, resistance training is especially important for the elderly. Cross-sectional studies have found that cognitive function and physical activity represent better performing performance. Muscle strength is the mediator of long-term exercise and executive function improvement, rather than the oxygen uptake peak. It is found that there is a positive correlation between cognitive function and sarcopenia. People with low cognitive function have a faster rate of lower grip strength. Whether muscle strength can regulate the effect of exercise on executive function needs further investigation. Purposes: The following three research purposes explore the effects of fixed resistance exercise intervention on muscle strength and cognitive function in the elderly, and explore the effects of fixed resistance exercise on muscle strength of the elderly. To explore the differences in executive function of different muscle strength levels in the elderly after a fixed resistance exercise. viii Method: The study recruited 60-year-olds from Beitou District, Taipei City, and divided them into two groups. The experimental group (n=46) performed a 12-week of resistance exercise. For action design choose chest press, lat pull down, leg press, leg curl, shoulder press, leg adduction and abduction. 2 times a week, 60 minutes each time, including a 10-minute bicycle/treadmill warm-up, improve the body's large muscle group temperature and improve joint mobility to avoid injury during exercise. The main movement is a four-week stage with a progressive principle with a strength of 50%-80% 1-RM. Muscle stretching exercises are performed in this part of each movement. Control group (n=68) matching the gender, age, education year and physical activity of the experimental group. The experimental group did not intervene any changes during the operation, maintained normal habits, and gave resistance exercise guidance after the experimental intervention was completed. Both groups were tested for physical fitness before and after intervention, measured skeletal muscle mass, body fat percentage. In the statistical analysis part, the chi-square and independent t-tests are used to indicate that there is no difference in the pre-test, and then the generalized estimating equation (GEE) is used to compare the experimental group and the control group after 12 weeks of muscle strength exercise. Conclusion: For 12 weeks, intensity 60% 1 RM-80% 1 RM, choose functional action as the action design consideration, each time 2 - 3 groups, at least 2 times a week of resistance exercise, the upper and lower extremity muscle performance of the elderly There is a significant improvement in grip and 30-second chair sit-up, and the body composition has a significant improvement in skeletal muscle mass and body fat percentage. The executive function, Sternberg Task test memory ability and response ix time have significantly improved, measuring cognition The accuracy and response time of Task Switch for flexibility and task conversion have improved significantly, and the Flanker Task for measuring suppression control has not improved significantly. Further exploration of the effect of different muscle strength on the executive function found that the response time of the low muscle strength group was better than the high muscle strength group, but this consistent result was not observed at the correct rate, that is, resistance training It has a positive impact on the executive function of the elderly, especially for the elderly with lower muscle strength. The effect is better than the muscle strength. If the habit of resistance exercise can be developed as early as possible, the body composition, upper and lower limb muscle strength, The executive function has a positive impact, so that we can truly avoid the impact of aging, implement prevention and delay, and achieve the goal of active aging.
