Dynamic Understanding Of Human-Skin Extension On Amateur Golfers Based On Motion Capture

In recent years,people are increasingly aware of the positive effects of high performance clothing on sports.Consumers pay more attention on function instead of fashion during sportwear selecting.With the continuous progress of science and technology,scientifically improved apparel has become an important factor influencing competitive performance.People now have higher expectation of clothing function not only for the professional golfers but also the amateur golf enthusiasts.This paper is based on the dynamic research results of the golf swing movement.Three-dimensional body scanning experiment gathered the data of three dimensional static state from 25 young men with golf experience.And then the research proposes a motion tracking method to collect skin markers’ coordinates throughout a full swing movement of the subjects selected based on the three-dimensional body scanning experiment results.Dynamic model of full swing was created,a map of maximum longitudinal and horizontal strain of upper body was found,key measurements that commonly used in clothing making were analyzed,area stretch pattern was obtained by comparing the maximum skin movement during nature swing and static position.Finally,suggestion has been provided for the high-performance golf apparel after combining the rules of skin movement and muscle group distribution.This results build a foundation for three-dimensional body data into two-dimension flat pattern,also helps to create structural design and to choose wearing ease and stretch ability.
