In Different Sport Forms Research On The Yong Female Breast Movement Characteristics And Subjective Feeling

Objective:The sports can bring many benefits to women, such as maintaining a healthy body and relieve pressure from work, life and so on, but there are also problems of breast pain, shaking the common, so we should strengthen the understanding of sports underwear, this study tested by kinematic indicators, through the analysis to find out the characteristics of female breast movement characteristics the law under different forms of exercise and breast pain and movement, and provide the reference for the sports underwear design and classification.Methods:This paper uses the Qualisys infrared high-speed motion capture test system in Sweden (6 shots), measurement of the subjects in the completion of badminton, aerobics movement kinematics indexes of the breast, and then were statistically analyzed, explore the changes of female breast movement characteristics under different forms of motion, and the possible mechanism, test time fill in the subjective evaluation form.Results:1 on the forehand hit better badminton movement, the left side of the chest in the take-off at the stage, mainly to the left, backward, upward movement, the displacement direction of the left than the right direction on the right side of the breast, mainly in the movement direction of movement mainly about. After the hit stage, the larger point about the left nipple, before and after, the vertical displacement change. Comparison of left and right side breast movement, right breast displacement increased significantly. The right nipple points in three coordinate axes are showing a lag in human motion phenomenon, basically lag 0.005s.2 rub the ball movement on the forehand, the left nipple point mainly to y axis movement, direction to left, backward, upward. Forehand chopping action in the left, right, thelion every axis direction of the sloshing amplitude, maximum speed are both appeared in the rolling ball before. On the forehand chopping action, left and right side nipple points in three coordinate axes are showing a lag in human motion phenomenon, the lag time is 0.005s.3 aerobics playing kick, the left nipples point mainly to Z axis motion, the direction to the left, back, down. Left and right side thelion maximum vibration range, speed appears to kick out stage between kicking stage. In calisthenics, left and right side nipple points in three coordinate axes are showing a lag in human motion phenomenon, the lag time is less than 0.01 s.Conclusion:Comparison of forehand, Gao Yuanqiu forehand Guoqiu, flick the aerobics movement, found in calisthenics, breast movement of human motion long time lag. Aerobics in the left and right side chest movement is consistent. Different movements chest pain and shaking feeling is not the same, and compared the research object of breast shaking discomfort than the more obvious pain and pain. The body feel there is a certain relationship between motion pain and rocking with the chest, but not a decisive factor. The body part of chest pain than shaking test parts, parts of the felt shaking up in thelion.
