Running economy (RE) is defined as the energy cost to maintain a submaximal running velocity and seems to be affected by individual's neuromuscular characteristics, such as stiffness level. Both resistance training (RT) and whole-body vibration training added to RT (WBV + RT) have been shown to influence those characteristics. Thus, it is conceivable that RT and WBV + RT could also affect RE. The objective of this study was to investigate if a 6-week training period of RT and WBV + RT influences RE and vertical stiffness (VS). Fifteen recreational runners were divided into RT or WBV + RT groups. Running economy, VS, and lower-limb maximum dynamic strength (1 repetition maximum [1RM] half-squat) were assessed before and after the 6-week training period. There was a main time effect for 1RM, but no other statistically significant difference was observed. Neither conventional RT nor RT performed on a WBV platform improved VS and RE in recreational long distance runners. It is possible that movement velocity was rather low, and utilization of stretch-shortening cycle might have been compromised, impairing any expected improvement in RE.
跑步经济性（RE）被定义为维持次最大跑步速度所需的能量消耗，并且似乎受个体神经肌肉特征（如僵硬程度）的影响。阻力训练（RT）以及在阻力训练基础上增加的全身振动训练（WBV+RT）均已被证明会影响这些特征。因此，可以推测阻力训练和WBV+RT也可能会影响跑步经济性。本研究的目的是调查为期6周的阻力训练和WBV+RT训练是否会影响跑步经济性和垂直刚度（VS）。15名业余跑步者被分为阻力训练组或WBV+RT组。在为期6周的训练期前后，对跑步经济性、垂直刚度和下肢最大动态力量（1次重复最大值[1RM]半蹲）进行了评估。1RM有主要的时间效应，但未观察到其他具有统计学意义的差异。在业余长跑运动员中，无论是传统的阻力训练还是在全身振动平台上进行的阻力训练，均未改善垂直刚度和跑步经济性。有可能运动速度相当低，且拉长-缩短周期的利用可能受到了影响，从而削弱了跑步经济性方面预期的改善效果。
