The Study Of Skin Deformation On The Body Trunk During The Golf Swing

In recent years, golf as a combination of enjoying the nature, physical exercise and game, receives extensive attention from many people. As the number of people involved in golf sport and people's consideration of safety and comfort increases, research on functional clothing is needed to impore golf enthusiasts' comfort and safety.This article shows the study of golf functional clothing based on clothing ergonomics. 1) First, by means of market research, we can have a preliminary understanding about golf apparel's prices and function sold in shopping malls and online stores. With analyzing the existing market status, we can find that the domestic golf apparel has an obvious tendency of fashionalization, but it is still insufficient in such aspects as structure and function. 2) Second, by the method of literature research, based on the golf sport itself, we can understand the muscles' movement condition in the golf swing and the human body's bone angle in the swing process. 3) Third, To conduct the golf 3D body scanning experiment, the study selected condition of rest and 3 representative action during the golf swing, the posture of address, backswing and the end of following through. By comparing the human skin's difference between these 3 posture and standing still to conclude the change of human body surface during playing golf.The study found that the change of human body surface is asymmetric all around when playing golf: 1) the primary parts of human body's linear variation range is between-40% and 50%, the horizontal lines of frontal body shrink significantly, and the horizontal lines of body's back expand significantly with the back's wide line stretching more than 40%; 2) Under the posture of takeaway, the results showed a significant shrink in the front of the body and a stretching in the back; Non-asymmetric changes were found during the analyses between two postures: the top of backswing and follow through the end; Skin deformation changes were found in relation to 3 specfic events of the golf swing, the main stretching parts were located in the following areas: left side of chest, under the armpit, upper side of back and lower back. Finally, combining the result of the research, it gives that the different sections' skin extension range of golf sport postures and structural division suggestion for golf clothing, providing theoretical guidance for high-performance golf clothing's research and development in the future.
