Abstract

The purpose of this study was to evaluate the acute effect of a Foam Roller (FR) warm up routine and a dynamic warm-up routine on strength, power, and reactive power using a squat jump (SJ) countermovement jump (CMJ) and depth jump (DJ). Nine college aged recreational males with a minimum of 1-year experience in plyometric training completed the study. Following baseline testing, subjectswere randomly assigned to a warm up protocol on the second session of the study and then completed the otherprotocol on the third day of the study. The best of three jumps were recorded. RMANOVA revealed a significant increase in jump height following the dynamic warm up in the CMJ (p=.018). A post hoc paired t-test revealed significance of (p=.015) between the FR to dynamic warm-up routines following the CMJ. All other jumps yielded decreases in performance, with no significant changes SJ (p=0.135) and DJ (p=0.145). A lack of significant change may be attributed to the removal of the trigger point (TrP) release from the FR due to the subjectivity of each individual’s pain level and amount of trigger points. In conclusion FR warm ups are not recommended prior to physical activity requiring increased neurologic activation as the FR warm up was shown to decrease jump performance as the neurologic demand of the jumps increased. Foam roller routines may be beneficial for the injured athlete prior to activity but should be followed by a dynamic warm up before partaking in activity.
