Influence Of Soft-ball Exercise On The Morphology And Bone Mineral Density In Elderly Female Body

Objective:To study the soft-ball exercise on the morphology and bone mineral density in elderly female body. To understand the physical mechanism of soft-ball exercise on elderly women by comparing the middle and old aged women, promote health, and promote scientific and feasible scheme of sports fitness, promote the physical health of elder women in China, and provide scientific basis for the national fitness service.Methods:the recruitment of Shaanxi Province, Xi’an city a community activity center for the elderly elderly women 45-65 years of age in 45 volunteers, divided into soft-ball team (25 people) and control group (20 people) as the subjects, soft-ball group of Softball Exercise by coach.19:00-21:00 exercise,4 times/week,2h/(15min 90min preparation activities, exercise, relaxation,15min) for 6 months. The control group did not exercise, keep the original state of life.Test index:before and after the experiment on two groups of volunteers to test indicators include:height, weight, waist circumference, hip circumference, skinfold thickness, waist hip ratio, fat mass and muscle mass, body fat percentage, BMI, bone density.Statistical methods:all data were processed by statistical software SPSS 17.0 and Microsoft Excel 2003 software. The results are the average+standard deviation. Before and after the experiment compared using paired samples T test, between different groups of independent samples T test was used for statistical processing, P< 0.05, there was significant difference, P< 0.01 is a very significant difference.The results of the study:(1) after 6 months of soft-ball Exercise, body weight and BMI index were decreased in elderly women. The abdomen, arm skinfold thickness has decreased significantly. Compared the abdomen, arm skinfold thickness and the difference was extremely significant (P<0.01). Body fat percentage decreased significantly, muscle weight increased, with statistical significance (P<0.05). In control group the body weight, BMI, waist circumference, waist to hip ratio and body fat weight were significantly increased than before the experiment, the difference is significant (P<0.01).(2) after the experiment of soft-ball group compared with before, the total body bone density of upper limbs, trunk, thigh and other parts of the value was slightly decreased, no significant difference. While in the control group after the experiment compared with before, the various parts of the body and bone density were significantly decreased, the difference was significant (P<0.01) and before the experiment.The conclusion of the study:(1)6 months of soft-ball Exercise can significantly improve the elderly female body shape index 45-65 years of age, body weight, BMI index, abdominal skinfold was significantly decreased, body fat content was significantly reduced, the body fat percentage significantly decreased, is conducive to weight control, related chronic diseases prevention of obesity, so the body composition of rationalization, and promote the health of middle aged and old women.(2) Compared with the control group before and after the experiment, bone mineral density and the various parts of the body were significantly decreased, while the soft-ball group before and after the experiment, the bone mineral density decreased slightly. Bone mineral content and the soft-ball group body, thigh, trunk and spine is lower than before, but there was no significant difference, there is a certain increase bone mineral content of the upper limbs, but there was no significant difference. While in the control group after the experiment, bone mineral content and body parts were decreased, which decreased the thigh and spine showed a very significant difference. That soft-ball exercise can ease the rapid decline in elderly women with bone mineral density and bone mineral content.
