Objective:Taking the mass exercise population as the object,we set up a first domestic grading standard of mass exercise techniques based on a scientific research procedure,aiming at promoting the participation of health building.As a means of refining the national fitness service system and carrying out it in a deep-going way,the Technique Grading Standard of Mass Table Tennis provides for the table tennis amateur lovers a certification standard.Method:The assessment structure of is defined by the questionnaire survey on 27 coaches and experts;the assessment index of mass table tennis technique grading is concluded by interviewing 69 coaches and experts,screening questionnaires and expert argumentation;the index weight of Grade I,II and III are computed by applying the Method of Index Number and Delphi's questionnaires to 15 experts;the assessment standard of mass table tennis technique grading is built by testing 621 table tennis lovers;the assessment standard is inspected by the inner back substitution of all the 621 samples and outer back substitution of 52 persons.Result:Defined an assessment structure of mass table tennis technique grading to assess the level of beginner to sports school by three grades and 9 sub-degrees(Dan);built an assessment index system of mass table tennis technique grading,including three subsystems(junior,intermediate and senior);set up an assessment standard of mass table tennis technique grading structured by six sub-standards(men's junior,women's junior,men's intermediate,women's intermediate,men's senior,women's senior).Conclusion:the inspection result of all-sample inner back substitution and outer back substitution indicates that the standard of this research can be perfectly applied to the technique grading assessment of mass table tennis.

Some diseases,such as coronary heart disease,atherosclerosis,hypertension,diabetes,breast cancer and endometrial carcinoma are related to overweight and obesity,which has been confirmed in the epidemiology.Besides,the epidemiology also reveals that,the weight control by means of walking movement and nutrition balance contributes to reduce the triglyceride in blood and the body fat;the weight loss is related to exercise frequency and fast walking distance;nutrition balance and the walking distance and time every time are in direct proportion to the value of weight loss.

本课题研究的目的是要研制出具有针对性的全民健身运动处方,以满足不同体质和追求个性化健身运动人的需求.编制出的运动处方软件,可为指导广大群众进行科学健身运动提供一个便利的使用工具.软件用Visual FoxPro数据库系统编写.建立了包括102个项目2000多条处方内容的运动处方数据库,160多篇健身小知识的知识库,饮食热量和能量消耗的计算库.具有锻炼项目较多,适用范围较广,使用时操作方便的特点.对实验和小规模试用效果较好.在部分社区体育指导站使用,受到使用者欢迎.

运用问卷调查、体质测量、数理统计与理论分析等方法对深圳市中小学生体质状况进行了研究.研究结果显示,深圳市小学生达到"国家标准"合格以上的人数占总人数的89%;2002年深圳市中小学学生的体质状况与2000年全国平均数比较,学生的身高略高,但体重增加明显.在素质项目中,握力,50米跑、立定跳远、50米×8跑、800米跑、1000米跑都比2000年全国的平均数略好,其他项目差异不明显.

对深圳市参加体质测试的12000名20～69岁成年、老年人中的1506人(男971、女535)用INBODY3.0人体成分分析仪测试后进行深入分析.采用IN-BODY3.0人体成份分析仪进行体重、脂肪含量、肌肉含量、腹部脂肪比等指标测试,并对数据进行严格审核后,再进行统计分析.分析了男、女BMI指数、脂肪比率和平均数的变化趋势,分别计算了男女BMI指数与脂肪比的相关系数和一元回归方程.研究测得了男、女性从20岁至60岁各年龄段肌肉比率与脂肪比率的平均数,并由此发现了男女性肌肉比率随年龄增加而逐渐减小,脂肪比率随年龄增加而逐渐加大的变化趋势.
