健身街舞对女大学生身体自尊及身体自我效能的影响

文章通过对普通高校女大学生进行为期12周的实验干预,以探讨健身街舞对女大学生身体自尊及身体自我效能感的影响效果。实验结果发现健身街舞对改善女大学生身体自尊和身体自我效能非常有效。这就为优化大学体育课程及女大学生运动健身的项目的选择提供了可靠的理论参考和依据。     

略论沈、汤的戏曲创作理论及其影响

在沈、汤论争中,沈碌力倡“音律说”、“本色论”,这对扭转明中期以来的不良创作风气起了一定的作用。同时也表现出明后期戏曲创作对音乐美、形式美追求的时代特色。但沈臻的理论忽视了作品的思想内容,客观上对明后期吴江派的戏曲创作及作品品评产生了不良的影响。汤显祖提出“文以意趣神色为主”,强调了作品的“曲意”、“意趣”,重视作品的思想内容,重视作品的机趣、神似、真色等问题,对明后期临川派作家的创作起了积极的推动作用。     

Nutritional intake and body composition changes in a UCI World Tour cycling team during the Tour of Spain

Abstract

The aim of this study was to quantify the food intake of an International Cyclist Union (UCI) World Tour professional cyclist team and to analyse changes in body composition during the Tour of Spain. Nine male professional road cyclists (31.3?±?3.0 years) volunteered to participate in the study. Nutritional data were collected each day throughout the 3-week Tour by two trained investigators who weighed the food ingested by the cyclists. Mean nutritional intake of the cyclists was as follows: carbohydrate, 12.5?±?1.8?g/kg/day of body weight (BW) (65.0?±?5.9%); fat, 1.5?±?0.5 g/kg/day BW (17.9?±?5.6%); and protein, 3.3?±?0.3?g/kg/day BW (17.1?±?1.6%). Intake of all micronutrients, except for folate, vitamin D and potassium (which were 78.7%, 46% and 84% of Recommended Dietary Allowances (RDA), respectively), exceeded the RDA. Height, weight, skinfolds, circumferences and diameters were taken following the guidelines outlined by the International Society for the Advancement of Kinanthropometry. Body density, body fat percentage, muscle mass, total muscle mass and fat mass of the arms and thighs were calculated. Percentage body fat, fat mass and upper arm fat mass significantly decreased (p < .05) after the Tour independent of the equation method used in the calculations. Total muscle mass remained unchanged. Generally, this sample of cyclists consumed more protein and less fat than the recommended amount and had low weight, BMI and fat mass. It is suggested that sports nutritionists design personalised diets in order to maintain a correct proportion of nutrients as well as controlling possible anthropometrical changes that could affect performance.

山西省大学教师身体机能状况和健康水平的调查研究

通过对山西省802名大学教师进行的体脂、心搏量等13个指标的测试,发现大学40—49岁两个年龄组的大部分指标与一般人区别不大,但体脂、体重较高,脉压较小,女子的血压也高。60岁以上组的大部分指标较同年龄一般人好,个别指标还较50—59岁组的好。说明中年教师的身体机能和健康水平较差,并针对性地提出了建议。
