采用文献资料法、测试法、问卷调查法、数理统计法对哈尔滨体育学院11个不同运动专项男大学生跟骨超声骨量进行研究,为黑龙江省体育院校大学生科学运动训练提供骨密度方面的资料。结果显示:田径、游泳、羽毛球、网球专项大学生跟骨超声骨量STI值高于同性别青年组平均值,且与对照组相比差异显著(P〈0.05);体操、篮球、乒乓球、排球、足球、跆拳道、柔道专项大学生跟骨超声骨量STI值低于同性别青年组平均值,与对照组相比差异不显著(P〉0.05)。得出不同运动专项、运动强度对我省体育院校男大学生跟骨超声骨量的影响不同。  相似文献

It is clear that, despite their natural tendencies, children have become less physically active in recent decades, with children today expending approximately 600 kcal· day -1 less than their counterparts 50 years ago. Although the health consequences of a reduced energy expenditure in adults is well documented, there is little direct evidence linking sedentariness with health in children. However, three main benefits arising from adequate childhood physical activity have been postulated. The first is direct improvements in childhood health status; evidence is accumulating that more active children generally display healthier cardiovascular profiles, are leaner and develop higher peak bone masses than their less active counterparts. Secondly, there is a biological carryover effect into adulthood, whereby improved adult health status results from childhood physical activity. In particular, childhood obesity may be a precursor for a range of adverse health effects in adulthood, while higher bone masses in young people reduce the risk of osteoporosis in old age. Finally, there may be a behavioural carryover into adulthood, whereby active children are more likely to become more active (healthy) adults. However, supporting evidence for this assertion is weak. Given this background, recent health guidelines suggesting that children should accumulate 60 min of moderate-intensity physical activity every day - supplemented by regular activities that promote strength flexibility and bone strength - appear to be justified. Future developments should include the implementation of large-scale, longitudinal studies spanning childhood and young adulthood, the further refinement of tools for measuring physical activity accurately in young people, and research into the relative strength of association between fitness - as well as activity - and health in children.  相似文献

The aim of this study was to determine the effects of long-term professional golf participation on whole-body and regional bone mass and density. Dual-energy X-ray absorptiometry was performed on 15 male professional golfers and 18 sedentary individuals, matched for sex, race, age (29 ± and 25 ± 1 years, respectively), body mass (79 ± 2 and 74 ± 2 kg), height (1.78 ± 0.01 and 1.77 ± 0.02 m) and percent body fat (20 ± 2 and 21 ± 2%; mean ± s χ). We found that long-term professional golf participation is not associated with significant increments in regional or whole-body bone mass or density. Neither the lumbar spine nor the femoral neck showed any noticeable enhancement of bone mass in professional golfers compared with controls from the same population. The only effect of professional golf participation on regional body composition was a 9% increase in muscle mass in the dominant arm (P ? 0.05).  相似文献

采用文献资料法、测试法、数理统计法对黑龙江省青年男子短道速滑运动员体成分及跟骨超声参数的特点及相关性进行研究,为其科学运动训练提供有关体成分及骨代谢方面的资料。结果显示:短道速滑运动员体重、体脂率和瘦体重与普通大学生相比差异显著,与体育类大学生相比差异不显著;短道速滑运动员跟骨超声参数T值显著低于普通大学生和体育类大学生;Pearson相关分析和多元线性回归分析得出身高、体重、身体质量指数、瘦体重与T值呈显著相关,瘦体重是决定跟骨超声参数的主要因素。得出长期高强度的运动训练对黑龙江省青年男子短道速滑运动员跟骨超声参数产生了不良的影响,维持和增加瘦体重及制定适宜的运动训练方案,对促进黑龙江省青年男子短道速滑运动员骨健康,提高运动员的运动能力,防治运动性损伤是有益的。  相似文献

Osteoporosis encompasses a wide spectrum of conditions associated with imbalance of osteoclastic and osteoblastic activities. The increased activity of osteoclasts leads to increased free radical formation and hence lipid peroxidation. Present study probes into the role of antioxidants as a palliative treatment for osteoporosis. It involved 50 healthy controls and 75 clinically diagnosed osteoporosis patients. Both the groups underwent baseline assessment of biochemical markers viz. osteoblastic markers: serum Alkaline phosphatase. Free or ionic calcium and Inorganic phosphorus, osteoclastic markers: serum Tartarate resistant acid phosphatase and Malondialdehyde and the antioxidant status: serum Superoxide dismutase and Erythrocyte reduced glutathione. The osteoporotic group was then divided into groups A (Vitamin E-Evinal 400 mg), B (Vitamin C-Celin 500 mg), C (Vitamin E+C-Evinal+Celin) for antioxidant supplementation for a period of 90 days. The results reveal that there is significant fall in concentration of serum MDA (p<0.001), TrACP (p<0.01). Improvement in antioxidant status is reflected by significant rise in concentration of serum SOD (p<0.001) and erythrocyte GSH (p<0.001) after 90 days of antioxidant supplementation in osteoporosis. The findings indicate that on the whole bone status improved with prolonged antioxidant vitamin supplementation, which can be used as a palliative treatment for osteoporosis. The efficacy is not affected whether the vitamins are administered singly or conjointly.  相似文献

目的:探讨链脲霉素(STZ)诱导的糖尿病对大鼠骨代谢的影响及机制。材料与方法:雄性Wistar大鼠随机分成3组: 正常组(n = 6),糖尿病组(n = 5)和胰岛素治疗糖尿病组 (n = 5)。大鼠尾静脉一次性注射STZ(50 mg/kg 体重),选择空腹12 h血糖大于12 mmol/L的大鼠为本实验所需的糖尿病模型。治疗组大鼠每天在同一时间给予1.8-2.2U的胰岛素。实验周期为持续32天。采用双能X线骨吸收法(DEXA)测定股骨密度,ELISA法测定血清雄性激素睾酮水平,生化分析仪测定血清碱性磷酸酶、钙、磷浓度。结果:糖尿病大鼠的股骨密度和血清睾酮均显著低于正常组(P < 0.01),血清总碱性磷酸酶明显高于正常组和胰岛素治疗组(P < 0.01)。三组之间血钙和血磷的水平无明显差异。胰岛素治疗后糖尿病大鼠的骨密度、血清睾酮与总碱性磷酸酶得到明显的改善。结论:糖尿病严重影响骨密度,胰岛素缺乏及雄性激素降低是导致糖尿病性骨质疏松重要原因。胰岛素治疗能预防骨流失和提高血清睾酮浓度。  相似文献
