Abstract
The purpose of the present study was to clarify the acute effect of dynamic stretching (DS) on relative high-intensity endurance running performance. The endurance running performances of seven well-trained middle or long distance male runners were assessed on a treadmill following two types of pretreatment. The pretreatments were non-stretching (NS) and DS treatment. In the DS treatment, DS was performed as one set of 10 repetitions as quickly as possible for the five muscle groups in lower extremities. The endurance running performances were evaluated by time to exhaustion (TTE) and total running distance (TRD) during running at a velocity equivalent to 90% maximal oxygen uptake (VO2max) in each subject. The oxygen uptake (VO2) during running was measured as an index of running economy (RE). The TTE (928.6 ± 215.0 seconds) following DS treatment was significantly (p<0.01) prolonged compared with that (785.3 ± 206.2 seconds) following NS. The TRD (4301.2 ± 893.8 meters) following DS treatment was also significantly (p<0.01) longer than that (3616.9 ± 783.3 meters) following NS. The changes in the VO2 during running, however, did not significantly (p>0.05) differ between the pretreatments. The results demonstrated that the DS treatment improved the endurance performance of running at a velocity equivalent to 90% VO2max in well-trained male runners, although it did not change the RE. This running velocity is equivalent to that for a 3000 or 5000 meter race. Our finding suggests that performing DS during warm-up before a race is effective for improving performance.
