EFEITO DO EXERCÍCIO AERÓBICO SOBRE A QUALIDADE NEUROMUSCULAR EM IDOSOS

Abstract

ABSTRACT Introduction: Physical activity has a good effect on improving the health of the elderly, especially in the treatment of chronic diseases of the respiratory, digestive, and cardiovascular systems. Many studies have proven that exercise, especially strength training, can delay and even reverse the decline in neuromuscular and motor function caused by aging, with a safe return to activities of daily living. The elderly generally choose an aerobic exercise for cardiovascular and endocrine benefits, but research on neuromuscular benefits has inconsistent results. Objective: Investigate the effects of aerobic exercise on neuromuscular quality in the elderly. Methods: Medical screening, background information questionnaire, and exercise habits were collected from 80 elderly people aged 65 to 80 years in two nursing homes in a given city. They were randomly divided into four groups without statistical difference. The male and female control groups maintained normal daily activities. In contrast, the male and female experimental groups practiced aerobic training exercises with progressively increasing intensity three times a week for 12 weeks. BMI, lean muscle mass and 6-minute walk test scores were collected. The software SPSS10 approaches t-test and data between groups compared by ANOVA (P<0.05). Results: The 6-minute walking distance of patients in the aerobic exercise group increased by an average of 20%. After aerobic exercise training, the 6-minute walking distance can increase by 10% to 18%. It shows that a certain intensity of aerobic exercise training can improve the submaximal exercise capacity of the patient, thus increasing the walking distance under the same exercise time. Conclusion: The aerobic exercise group is better than the control group at changing the body shape of the elderly by reducing fat and increasing lean body mass, while the control group has apparent effects on increasing muscle mass, strengthening muscle strength, and strengthening muscle function.Evidence Level II; Therapeutic Studies - Investigating the result.
