运动减肥中运动强度的确定及在肥胖青少年运动减肥中的应用

Determination of Exercise Intensity and Application of Obese Adolescents in Fat-reducing Exercise

依据无氧阈理论,探讨运动减肥强度的确定方法,为制定科学的运动减肥处方提供建议。首先,令受试者在实验室进行运动试验,采指尖血测血乳酸值,计算无氧阈值(%VO2max、HRAT和乳酸阈速度),建立起无氧阈值与体脂百分比之间的关系;然后利用实验结论,指导6名肥胖青少年进行为期1个月的减肥实践,结果发现:无氧阈值与体脂百分比之间呈显著的中度负相关(P<0.05),随体脂百分比值增加呈下降趋势;1个月减肥实践后肥胖青少年体重和体脂肪均有显著降低(P<0.05)。采用测定个体无氧阈强度的方式监控运动减肥中的运动强度,在实践中取得一定成效。

Objective：according to theory of anaerobic threshold,to determinate exercise intensity in order to supply suggestive ideas for developing scientific exercise prescription.Methods：including two experiments：the first was designed to blood to measure and calculate lactate and anaerobic threshold（%VO2max,HRAT and lactate threshold speed）,and establish relationship between anaerobic threshold and percent of body fat;the second was designed to guide 6 obese adolescents for one month exercise to lose weight.Results：there was moderate negative correlation between anaerobic threshold and percent of body fat（P0.05）;both weight and body fat had declined significantly（P0.05）after one month exercise.Conclusion：to monitor exercise intensity by measuring individual anaerobic threshold intensity,and achieving some success in practice.
