Background: The effects of PNF CR on the muscular strength, ROM of the 20s male and female college students were investigated using the maximal contraction of the antagonistic muscle.
Method: The all subjects are healthy and participated voluntary We had divided 2 group (12 people to compare group, 12 people for the contract relax group) and the effects on ROM were measured with goniometer and muscular strength were measured with Power Dynamometer. And the t-test was conducted to analyze among the compared group, the contract relax group the differences between before and after the experiment.
Result: Contract relax group was a muscular strength and ROM showed significant results(p<0.05) between before and after CR. The control group, however, showed no change(p>0.05).
Conclusion: This study demonstrated that contract relax could be helpful for muscular strength and ROM. Various techniques in future research on muscle relax exercises can be studied to promote the public if the functional status is considered to be of much help.
