Background: Beach woodball has been an event in the Asian Beach Games for five consecutive sessions, but the hitting distance is shorter due to the characteristics of the beach, causing the load on players' forearms to increase. Purposes: This study used a five-minute myofascial relaxation technique to intervene in the long-distance hitting swing of beach woodball. The main purpose is to quickly restore the elbow joint movement angle of the dominant hand (bending, forearm pronation, forearm supination) and wrist joint movement angle (bending and straightening). The secondary purpose is to restore the grip strength of the dominant hand. Method: A total of 24 college woodball players aged 20-29 were recruited. The elbow joint angle (bending, forearm pronation, forearm supination), wrist joint (bending and straightening) and grip strength of the dominant hand after repeated swinging 36 times and intervention of myofascial relaxation for five minutes were measured before long-distance swinging. The single factor repeated measure ANOVA was used for quantitative analysis, and Bonferroni was used for post-test analysis. Results: The angle change of the elbow joint had positive change and significant difference in bending angle after myofascial relaxation intervention and before swinging (p＜.05). After repeated swing-myofascial relaxation intervention, the angle of the elbow joint (bending, forearm pronation, forearm pronation) has positive change and significant difference (p＜.05). After repeated swing-myofascial relaxation intervention, the angle of the wrist joint has positive change and significant difference (p＜.05). Before swing and after myofascial relaxation intervention, the angle of the wrist joint (bending and straightening) has no significant difference before and after repeated swinging 36 times. The grip strength of the dominant hand was significantly different, but no significant difference was found in each group after verification. Conclusion: Five-minute myofascial relaxation intervention can help athletes to make positive changes in the angles of the elbow joint (bending, forearm pronation, forearm pronation) and wrist joint (bending, unbend) of their dominant hand after repeated swinging 36 times, but it is not helpful to restore the grip strength of their dominant hand.
