The subjective Volodalen® score (V®score) and the objective duty factor metric can both assess global running patterns. The authors aimed to investigate the relation between running economy (RE) at endurance running speeds and the global running pattern quantified using both subjective and objective measures.
RE and 3-dimensional whole-body kinematics were acquired by indirect calorimetry and an optoelectronic system, respectively, for 52 trained runners during treadmill runs at 10, 12, and 14 km/h.
Correlations between RE and V®score and RE and duty factor were negligible and nonsignificant across speeds tested (P ≥ .20), except for a low and significant correlation between RE and V®score at 10 km/h.
These findings suggest there is no global running pattern more economic than another at endurance running speeds. Therefore, there is no advantage of choosing, favoring, or prescribing one specific global running pattern along a continuum based on V®score or duty factor metrics, and coaches should not try to modify the spontaneous running pattern of runners at endurance running speed to improve RE.
主观Volodalen®评分（V®评分）和客观负荷因子指标均可评估整体跑步模式。作者旨在研究耐力跑速度下的跑步经济性（RE）与使用主观和客观测量方法量化的整体跑步模式之间的关系。
分别通过间接量热法和光电系统，对52名训练有素的跑步者在跑步机上以10、12和14公里/小时的速度跑步时的RE和三维全身运动学进行测量。
在测试的所有速度下，RE与V®评分以及RE与负荷因子之间的相关性均微不足道且无统计学意义（P≥0.20），但在10公里/小时时，RE与V®评分之间存在低水平的显著相关性。
这些发现表明，在耐力跑速度下，不存在一种整体跑步模式比另一种更经济。因此，基于V®评分或负荷因子指标在连续统一体上选择、偏好或规定一种特定的整体跑步模式没有优势，并且教练不应试图在耐力跑速度下改变跑步者的自发跑步模式以提高RE。
