摘      要：BACKGROUND： Plyometric training has been shown to improve performance in distance running events up to 5-km, but little research has been done on this type of training for marathon （42.195-km） runners. The purpose of this study was to examine the effects of plyometric and explosive speed training （PLYO） on recreational marathoners. METHODS： Twenty-two subjects （ages 18-23）, were randomized to either PLYO or core training （CORE） for a weekly session performed for 12 weeks, in addition to marathon training. Sprint, jump, and distance running performance variables were measured pre- and post-intervention. RESULTS： In the sprint tests, the PLYO group improved in both the 200-m run （P ≤ 0.001） and 60-m run （P = 0.004）, and trended toward improvement in the 30-m fly （P = 0.051）. The difference from CORE was significant only in the 200-m （P = 0.002）. The CORE group did not change in any of the sprint or jump variables. The PLYO group was significantly different from the CORE group in the standing long jump （P = 0.024）. There were no differences between groups in distance running performance. Both improved in 2-mile （3.219-km） time trial （p 〈 0.001）, VO2MAX （P = 0.026 for CORE; P = 0.002 for PLYO）, and running economy （P = 0.01）. CONCLUSION： Weekly PLYO training improves sprint speed and maintains jumping ability in recreational marathoners, but does not augment improvements in distance running performance.
