The acute effects of different stretching methods on golf club swing speed, specifically related to isometric pelvic strength and pelvic range of motion.

Stretching, the voluntary elongation of a muscle, can increase blood flow, loosen muscles and tendons, and increase range of motion prior to activity. Shortened hip flexors and adductors including the iliopsoas, adductor brevis, and adductor magnus, limit motion at the lumbopelvic region, affecting motion in both the frontal and transverse planes. Despite the unilateral nature of golf, improved flexibility and strength in both directions are advantageous. Stretching prior to competition has been shown to enhance range of motion and strength in the lumbopelvic region, facilitating greater rotational forces and speed in the downswing. This ultimately increases club head speed and ball distance, offering a competitive advantage. Methods like static and dynamic stretching could aid in maximizing a golfer's potential by increasing club head speed. Therefore, the purpose of this study is to examine the effects of static and dynamic stretching procedures of the lumbopelvic hip complex on club head speed, hip range of motion, and hip isometric strength among collegiate golfers. Participants will include collegiate golfers between the ages of 18 to 24, divided randomly into three groups: a control, a dynamic stretching protocol, and a static stretching protocol. For pre-test assessment, range of motion will be assessed using a digital inclinometer, and isometric strength will be assessed using a handheld dynamometer. Participants will be in a supine position for flexion, prone position for extension, and a seated position for hip rotation. Next, swing speed will be determined using FlightScope launch monitor while each participant takes three swings using a driver. Participants will then perform their assigned stretching protocol. Post-test procedure would follow pre-test protocol. We expect to see an increase in hip range of motion, lumbopelvic-hip complex isometric strength, and club head speed among the dynamic stretching group when compared to both the static and control group.
