Three Months Endurance Exercise The Body Mass Index-based Aerobic Capacity Of The Fourth Graders

The maximum oxygen uptake are human maximal aerobic exercise capacity, one of the main indicators. Determination of maximum oxygen uptake for the evaluation of growth and development of primary level, the potential of cardiopulmonary function and quality of exercise is of great significance. Based on the experimental group pupils for a three-month aerobic endurance exercise and the results with the control group, the training before the experimental group carried out a comparative analysis of three-month trial period to explore the ability to work on the aerobic and physical shape and quality of sports impact.Research subjects for Anyang Ruian Wenzhou City Experimental Primary School fourth grade students, average age 10.3 years old, a total of 122 people, 69 boys and girls 53 people, at the number provided for the experimental group, under the premise were randomly divided into experimental group and control group. One of the control group of 93 people, (male 54, female 39 people); the experimental group of 29 people, (male 15, female 14 people). Effective after training the experimental group the number of boys and 15 girls 14 people. Know in advance the physical condition of students, has ruled out physical injury as well as students who have chronic diseases.This dissertation research methods including literature, experimental and mathematical statistics and comparative study of law. Direct measurement of all items with reference to "student's health standards" required to carry out measurement, pupils know the physical health status. Indirectly, the largest projected absolute oxygen uptake: The Karepuman formula, first obtained experimental stage PWC170 power, then by the maximum oxygen uptake values of power projection. Explore the maximum oxygen uptake and lung capacity, the relationship between the chest and set up the regression equation.The experimental results show that: (1) to test students with the various indicators of national student diversity analysis, in addition to height, the differences are partly exist very significant difference. (2) formula Karepuman oxygen uptake child's best projections are feasible, the maximum oxygen uptake test the level of lower-middle, with the greatest amount of oxygen to the relative value than the absolute value of a good grade. (3) the control group at three-month period for men and women must have the height and weight growth, height and weight of boys, there was a significant difference, other indicators do not exist significant difference. (4) the experimental group and control group before and after training, male and female height and weight do not exist significant difference, but the growth of the proportion of the experimental group than the control group, and men and women in standing long jump, vital capacity, PWC170 on significant differences exist, the boys in the maximum inspiratory oxygen exist on the absolute value of significant difference between the girls at the largest on the relative value of oxygen uptake, there was a significant difference. Shows that training has reached the body improve the effectiveness of aerobic work capacity. (5), the experimental group before and after training, for boys and girls at PWC170 and maximum oxygen uptake in absolute terms on all exist significant differences in body shape and exercise quality indicators, apart from the weight of females, there was a significant difference, the other did not statistical difference. However, the growth in the proportion of training than the control group values in a certain extent, training or exercise on the body shape and play a positive role in the quality. (6) the largest absolute value of oxygen uptake and lung capacity of the regression equation with the relevant book of the Department of R, male Y = 0.7585x +628.44, R = 0.677, a high positive correlation, girls, Y = 0.4017x +1151.2, R = 0.583, moderate positive correlation; maximum oxygen uptake Maximum oxygen uptake and the relative value of the regression equation between the chest and the correlation coefficient R, for boys, Y = 0.4676X +37.547, R = 0.67 a high positive correlation, girls, Y =- 0.5309X +91.708, R = 0.554, moderate negative correlation girls there a negative correlation may be related to the physical development of girls concerned. (7) for three months can be used as a stage measures, to a certain extent improve the primary job of aerobic capacity, body shape and for the quality of sport must also have positive effects.
