Immediate Effects of Foam Roller and Stretching to Lead hip on Golfers Swing: A Randomized Cross-over Trial

We hypothesized that increasing the leading hip internal rotation (IR) range of motion (ROM) would decrease lumbar rotation ROM during the golf swing. The subjects were healthy 22 males. Two groups were Foam roller and stretching (FR+ST) or practice swing (SW). Motion analysis was used to evaluate hip and lumbar ROM.This data shows the changes in golf swing motion and physical function after the intervention in golfers. Leading hip IR ROM during the golf swing was significantly greater in the FR+ST group. The FR+ST group showed a moderate negative correlation between leading hip IR ROM and lower lumbar spine Lrot ROM during the golf swing. Foam roller and stretching might be useful for increasing lead hip IR ROM during the golf swing. Moreover, FR+ST groups suggested that improved lead hip IR ROM may decrease lumbar spine Lrot.

本研究提出假设：提升主导侧髋关节内旋（internal rotation, IR）活动度（range of motion, ROM）可降低高尔夫挥杆过程中的腰椎旋转活动度。研究对象为22名健康男性受试者，分为两组：泡沫轴放松与拉伸组（Foam roller and stretching, FR+ST）及模拟挥杆练习组（practice swing, SW）。采用运动分析技术评估髋关节与腰椎的活动度。本数据集展示了高尔夫球手接受干预后，其高尔夫挥杆动作与身体机能的变化情况。结果显示，FR+ST组受试者在高尔夫挥杆时的主导侧髋关节内旋活动度显著更高；且该组受试者的主导侧髋关节内旋活动度与挥杆过程中的下腰椎旋转活动度呈中等程度负相关。研究表明，泡沫轴放松与拉伸或可提升高尔夫挥杆时的主导侧髋关节内旋活动度；此外，FR+ST组的结果提示，主导侧髋关节内旋活动度的提升可能降低腰椎旋转活动度。
