Effects of Varying Warmup Stimuli on Running Economy

<p><strong>Purpose</strong>: The purpose of this study was to determine the effects of two potentiating warm-up stimuli (weighted-vest strides and plyometrics) on running economy (RE) over short (5-10 minutes) and longer durations (30+ minutes) of exercise in trained distance runners. <strong>Methods</strong>: Five recreationally trained male runners were recruited to participate in this study. Each trial consisted of a 10-min self-paced warm-up on the treadmill followed by baseline RE test and baseline leg-stiffness. This was immediately followed by one of two intervention warmup protocols. The protocols consisted of either a series of plyometric movements, 6 x 10-sec strides with a weighted-vest equal to 20% body mass, or a control intervention. Following the intervention, a 10-minute resting period was included to elicit the effect of waiting in a coral pre-race. Following the resting period, a post-intervention RE test and leg-stiffness test were recorded. A 30-min endurance run on the treadmill followed the post-intervention RE and leg-stiffness tests followed by a final RE and leg-stiffness test. HR and RPE were recorded throughout the RE portions of the trials. <strong>Results</strong>: There was no statistical significance supporting the effect of condition (p=0.535) or time (p=0.238) on RE or on power (p=0.061) as a result of the interventions. There was a statistically significant effect of time on RE from the post-intervention to post-30-min run (p=0.012). <strong>Conclusion</strong>: There was no statistically significant effect of intervention condition on RE or power via leg-stiffness in recreationally trained distance runners.</p>
