Consistent with our hypotheses, the current investigation found that DS caused an acute ergogenic improvement in all kinetic parameters 1 min after stretching when compared to an equal duration of SS. Additional findings were that a prior bout of SS caused an acute deleterious effect in all kinetic parameters 1 min after stretching. No significant effect was detected for any variables at 15 min. Together these findings suggest that short durations of SS and DS can substantially alter several important kinetic parameters involved in maximizing vertical jumping performance, but only Selleckchem FK228 for a brief period of time after stretching. There is very little research that has investigated

the acute effects of different stretching strategies in the female athlete, but conflicting results have emerged. For example, some authors25 and 26 have reported that a prior bout of SS and DS displays no notable effect on vertical jumping values in collegiate women. However, other authors found that a prior bout of SS and DS caused significant effects in collegiate women when performing SSC activities of vertical jumping27 and

reactive muscle strength.4 These unclear observations parallel findings from a very recent review of the literature, where the authors report that approximately half the studies involving SS and DS showed no notable effect on SSC performance.8 Thus, it was the intent of this investigation to provide SAHA HDAC in vitro a biomechanical understanding during a commonly utilized SSC movement (vertical jumping) after two specific stretching strategies in a sport-specific and gender-specific population Rolziracetam as a means to add clarity to the present conflicting research findings. Quantifying the dynamic RFD after stretching was one priority in this investigation because when examining explosive muscular strength in athletes and how it is mechanistically linked to sport performance,

RFD has been deemed to be the most important predictor variable affecting performance in sports requiring a high level of acceleration.28 Previous work has demonstrated that SS for a total duration of 10 min elicited acute decrements in RFD and Fpk in recreationally active males. 22 The present investigation is in agreement with previous evidence in that SS for 7 min total duration impaired RFD and Fpk scores 1 min after SS. Other investigators 2 and 21 however, have found no notable effects of Fpk and RFD after SS. This may have been attributed to the likely positive effect of the dynamic warm-up performed with SS prior to performance testing. In this context, the current investigation utilized a sport-specific DS session and it was found to have a clear notable improvement in RFDavg and Fpk values at 1 min after stretching when compared to the same duration of SS.
