The purpose of this research is to investigate the effects of elastic band exercise on Junior Golfers' wrist range of motion and wrist muscle strength.
Subjects of this test are 14 students in junior middle or high school who do not have any musculoskeletal system disorder (MSD). 7 students were assigned to experimental group in which they participated in elastic band exercise and golf skill practice simultaneously while other 7 students were assigned to control group in which they focused only on golf practice. Experimental group practiced elastic band exercise which includes flexion, extension, pronation, supination, radial deviation, and ulnar deviation exercises three times a week for 8 weeks. Wrist range of motion, grasping power, and muscle strength were measured. Flexion, extension, pronation, and supination were measured by Biodex at angular speed of 60˚/sec for muscle strength.
The results earned through a process above are like following.
1) Measurements before and after the experiment, and changes in those measurements were studied. The experimental group showed statistically significant changes on flexion, extension, pronation and supination of left wrist, (<0.05), and on flexion, extension and supination of right wrist. The results showed that 8 weeks of elastic band exercise amplified wrist range of motion at statistically significant level.
2) Measurements before and after 8 weeks of elastic band exercise revealed statistically significant changes on grasping power of both left and right hands for the experimental group. 8 weeks of elastic band exercise enhanced junior golfers' grasping power at statistically significant level.
3) Measurements of isokinetic muscle strength before and after the experiment showed statistically significant changes of left and right flexion muscle strength, extension muscle strength, pronation muscle strength, and supination muscle strength in both peak torque and total work. Only from total work of right wrist pronation muscle strength, there was no statistically significant change. 8 weeks of elastic band exercise increased wrist muscle strength by statistically significant level.
4) Before the experiment, there was no statistically significant difference between the experimental group and the control group. However, after the experiment, the experimental group and the control group showed statistically significant difference in left and right muscle strength, extension muscle strength, and pronation muscle strength in both peak torque and total work. For supination muscle strength of left wrist, there was no statistically significant difference observed in both peak torque and total work. For the supination muscle strength of right wrist, there was statistically significant difference observed in peak torque but not in total work. After the experiment, the experimental group showed larger increase in wrist muscle strength than the control group.
