The acute effect vibrating foam rollers have on the lower extremities' ability to produce power

<p>The purpose of this study was to examine the effect that vibration through self-myofascial release in combination with a dynamic stretch routine had on maximum power output. Twenty-one collegiate volleyball athletes agreed to participate in the study. The design was a randomized cross-over design in which all participants served as their own control by participating in all three interventions, which consisted of; a) dynamic stretch routine (DS), b) non-vibrating foam rolling combined with dynamic stretch routine (NVFR), and c) vibrating foam rolling combined with dynamic stretch routine (VFR). The foam rolling protocol consisted of rolling each limb bilaterally for 30 seconds; four and a half minutes in total, and was followed with the dynamic stretch routine. Subjects then participated in the vertical jump test, using a Just Jump Mat. Each participant was given one practice attempt, and three recorded attempts that were averaged, and used for statistical analysis. Testing days were separated by a minimum of 48 hours and were completed at the same time of day. A repeated measures ANOVA was calculated to compare the mean scores of the jump height and power for each warm-up condition. This study found there to be no significant difference between jump height due to the warm-up condition (F(2,40)=1.705, p=0.195, ηp2=0.079). This study also found there to be no significant difference between jump power due to the warm-up condition (F(2,40)=1.754, p=0.186, ηp2=0.081). However, this study did indicate a significant difference in the perceived effectiveness of the warm-up condition (F(2,40)=5.043, p=.011, ηp2=0.201, CI=[0.213,1.120]). In conclusion, the present study indicated that vibrating foam rolling combined with dynamic stretch did not have a significant effect on jump height in female collegiate athletes.</p>
