The Relationship between Change of Direction Speed in the Frontal Plane, Power, Reactive Strength, and Strength

International Journal of Exercise Science 7(4) : 260-­270, 2014. Change-­of-­direction speed (CODS) is an important quality to performance in multi-­direction sports. The relationship between CODS in the frontal plane and power, strength, and reactive strength is largely unstudied. Twenty-­three male college students participated in this study. The study used a -­moment correlation to measure the relationship between CODS, power, strength, and reactive strength. A lateral shuffle test was used as the measure of CODS. A lateral hop for distance was used as the measure of power in the frontal plane. A countermovement vertical jump test was used as the measure of power in the sagittal plane. A depth jump was used as the measure of reactive strength in the sagittal plane. A 3RM squat test was used as the measure of strength. There was a moderate relationship between the lateral shuffle test and the lateral hop (r =.541, p = .008 and r =.567, p = .005), but no significant relationships with the countermovement vertical jump, depth jump, or squat test. These results suggest that power should be trained in all planes to improve CODS performance in multi-­direction sports, and that CODS should be trained in its sport-­specific context.
