Experimental Research on Basis of Defining Exercise Intensity for Fat-reducing Exercise

It used the experimental method to measure the indexes of aeroblic capacity,air metabolism such as respiratory quotient etc.and anaerobic exercise capacity of three groups of subjects separately with low,middle and high body fat percentage during the load-gradually-increasing exercise and to do research on the relations of body fat percentage to the above three kinds of indexes.The results reveal that the body fat percentage has a significantly negative correlation with each index of aerobic and anaerobic capacities;under the condition of all samples' exercise ability being in low level,the group of subjects with high body fat percentage are weaker in both aerobic capacity and anaerobic capacity;and during the load-gradually-increasing exercise,their respiratory quotients increase greatly and come to higher level near lactate threshold.All these indicate that the high body fat percentage is a factor of restricting body exercise ability,and to those individuals with lower sports level,in the condition of lower load,it is of great importance to define the intensity of fat-reducing exercise in combinaton with respiratory quotient.It pointed out that the fatter the persons were,the lower their lactate thresholds were,if so,the relatively lower exercise intensity could only be used in the fat-reducing exercise.
