【摘要】：目的:以32名中年男性作为研究对象,通过16周健身跑运动对中年男性的双侧下肢骨密度和身体成分的变化规律。为广大的低骨密度、肥胖、身体成分不合理的人群,提供健身方案。通过理论与实践的结合,探讨分析健身跑运动对中年男性身体健康的影响,为提高我国中年男性体质健康水平提供科学依据。方法:从初选50名中年男性中,经过健康排查后挑选符合条件的32名男性作为研究对象,对该人群进行16周健身跑运动。观察运动干预对中年男性下肢双侧骨密度和身体成分相关指标的影响。选用体重指数(BMI)、骨密度(BMD)、骨矿含量(BMC)、肌肉含量(SLBM)、脂肪含量(FM)、去脂体重(FFM)和脂肪百分比(PBF)等多个指标进行运动干预前后比较。运动强度:根据GXT测试,判定纳入受试者的通气无氧阈(AT)。确定75%,85%,95%和100%AT对应的心率(HR)作为运动强度,各阶段以相应运动强度进行运动。各个指标的测试结果以平均数±标准差(x±s)表示,运用SPSS17.0软件进行统计学分析,组内实验前后的比较采用配对样本T检验,P0.05为有显著性差异,P0.01为有非常显著性差异。结果:(1)经过16周的健身跑运动45—49岁的中年男性BMD、BMC、SLBM和FFM比运动前有显著提高(P㩳0.05),FM和PBF的值比16周运动前减少,差异非常显著(P㩳0.01)。BMI也有一定的减少但差异不显著。(2)50—54岁受试者进行16周的运动干预后BMD和BMC的值比运动前有显著提高(P㩳0.05),FM和PBF呈下降趋势,并且差异显著(P㩳0.05)。FFM的值比16周运动前有一定的增加,BMI比16周运动前有所减少,FFM和BMI的值运动前后没有差异性。(3)55—59岁受试者BMD、BMC、SLBM、FFM经过16周健身跑运动干预后呈上升趋势,其中BMD存在显著差异,经过16周的训练后BMI、FM、PBF的值呈下降趋势,FM和PBF差异非常显著(P㩳0.01)。(4)经过16周的健身跑运动后45—49岁的受试者骨密度、骨矿含量和肌肉含量的变化值比50—54岁和55—59岁受试者的变化值明显,3组间体重指数、脂肪含量的变化值没有差异性。结论:(1)16周的健身跑运动后中年男性下肢骨密度和骨矿含量的值都有提高,说明16周的健身跑运动有利于增加中年男性下肢的骨密度和骨矿含量。(2)16周的健身跑运动后中年男性的肌肉含量、去脂体重的含量均有增加,而脂肪含量呈下降趋势,16周的健身跑运动改善了中年男性下肢身体成分。(3)16周的健身跑运动后,三个年龄段中45—49岁中年男性下肢的骨密度、骨矿含量和肌肉含量提高最多,说明本文的健身方案对45—49岁受试者的健身效果优于50—54岁和55—59岁的受试者。
[Abstract]:Objective: to study the changes of bone mineral density (BMD) and body composition of bilateral lower extremities in 32 middle-aged men. Through the combination of theory and practice, this paper discusses the effect of running exercise on the health of middle-aged men. Methods: from 50 middle aged men in primary election, 32 eligible men were selected as the research objects after health examination. The effect of exercise intervention on bone mineral density (BMD) and body composition in lower extremities of middle-aged male was observed. Body mass index (BMI) and BMD (BMD) were selected. Bone mineral content (BMC), muscle content (SLBM), fat content (FM). FFM and percentage of fat were compared before and after exercise. Exercise intensity: according to GXT test. Determine the anaerobic threshold of ventilation in the subjects. Determine 75% and 100 AT corresponding heart rate HRs as exercise intensity. The test results of each index were expressed as mean 卤standard deviation x 卤s, and the statistical analysis was carried out with SPSS17.0 software. The comparison before and after the experiment in the group using paired sample T test was significant difference (P0.05). P0.01 was a significant difference. Results: after 16 weeks of exercise, BMD-BMC, a middle-aged male aged 45-49 years, was tested. SLBM and FFM were significantly higher than before exercise. The values of FM and PBF were lower than those before 16 weeks exercise, and the difference was very significant. There was also a decrease in BMD and BMC in subjects aged 50 to 54 after 16 weeks exercise intervention, but the difference was not significant. The values of BMD and BMC were significantly higher than those before exercise. The FM and PBF showed a decreasing trend, and the difference was significant (P < 0.05). The value of 0.05U. FFM was higher than that before 16 weeks exercise, and BMI was lower than that before 16 weeks exercise. There was no difference between the values of FFM and BMI before and after exercise. The values of BMD-BMC and SLBMM-FFM of 55-59 years old subjects showed an upward trend after 16 weeks of exercise intervention. After 16 weeks of training, the value of BMD showed a downward trend. The difference between FM and PBF was very significant. After 16 weeks of exercise, subjects aged 45-49 had bone mineral density (BMD). The changes of bone mineral content and muscle content were significantly higher than those of the subjects aged 50-54 and 55-59 years. Conclusion the bone mineral density (BMD) and bone mineral content (BMD) of lower extremities of middle aged men increased after 16 weeks of exercise. The results showed that 16 weeks of exercise was beneficial to increase the bone mineral density and bone mineral content of lower limbs of middle-aged men. After 16 weeks of exercise, the muscle content of middle-aged men and the content of fat-free body weight were increased. However, the body composition of the lower extremities of the middle-aged male was improved after 16 weeks of fitness running, which showed a decreasing trend of fat content. Bone mineral density (BMD), bone mineral content (BMD) and muscle content (BMD) of lower extremity were increased most in middle aged males aged 45-49 years. The results show that the fitness effect of the program is better than that of the subjects aged 50-54 and 55-59.
