Abstract
Objectives : Elbow injuries are likely to generate a loss of range of motion which might impact athletic performances. The effect of elbow stiffness on endurance running performance has never been investigated. The goal of our study is to evaluate the effect of elbow stiffness on running economy.
Design : Observational, prospective, cross-over study.
Methods : Twenty trained athletes performed running economy tests at 12 km∙h-1, with and without a limited elbow ROM of 90° of flexion and an extension deficit of 45° imposed by a dynamic brace.
Relative intensity and performance indexes were measured during a subsequent maximal incremental exercise test.
Results : Running economy was measured at 180 ± 10.6 (mlO2∙km-1∙kg-1) with a full range of motion and at 180.2 ± 12.3 (mlO2∙km-1∙kg-1) with the limited range of motion. This 0.1 % difference was not statistically significant (p = 0.871).
Conclusions : Athletes with a post-traumatic elbow stiffness can be reassured on its impact on their endurance running performance, as it does not appear to affect running economy. Further research could explore elbow movement at different intensities of running, from higher aerobic speeds to sprint.
