College Volleyball Specialized Course In Common Research Practice Ball Technology Means The Exercise Load

School physical education is a"Machine Tools" as a training school sport, university physical education specialized puts forward higher requirement on its practical teaching. Physical education professional skill teaching should not only make the students master the sports technology and skills, but also to enable students to master sports teaching skills. Reasonable arrangement of exercise load of mastering sports technology and skills have significant impact. However, at home and abroad,the research about exercise load of commonly used teaching methods in volleyball ball has not yet clear, in this paper, exercise load of commonly used teaching methods in volleyball ball were discussed, expect can provide some references for the volleyball teaching course of physical education design.In this paper, using of literature experimental and other research methods, choose students of physical education professional in volleyball in Nanjing normal university as experiment object, analyze energy consumption of commonly used teaching method in volleyball ball, and the experimenter wear actigraph instrument to record energy consumption data. Through to the related data statistics and analysis, get the following conclusion:(1) The same form of exercise load for students of different gender are different. The exercises load of the girls more than the boys in shift class, two people throwing trainning class, but the girls is less than the boy in the wall to practice; The same technology practice to load of the girls more than the boys (except block class practice). With the different form, the change of load both girls and boys are the same.(2) In the same conditions, both boys and grils, bounce class exercises load were greater than the other class.(3) The same technology practice for students of different gender exercise intensity is different, the boy’s technology practice belongs to the high intensity activity, the girls technology practice belong to severe activity; Same practice form is the same exercise intensity for different gender, the intensity of boys and girls are between moderate and great strength.(4) Forms of exercise load caused by differences in factor including psychology factors and skills. Practitioners of the stronger the spatial perception of ball bearing, speed and distance judgment more accurate, the stronger of the time perception, the better movement rhythm, the stronger of the motion perception, the smoother of completion; the more skilful technology,the less energy consumption,the more complex technology, the more energy consumption.
