Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Interlimb asymmetry has previously been related to higher injury risk as well as to impaired sports performances. Nevertheless, to date, research on the degree and evolution of functional asymmetry (e.g., unequal strength between limbs) in distance runners is scarce and the role of functional asymmetries in running performance and running-related injuries remains unclear. Moreover, and despite the great number of unilateral tests available in the literature, there currently exists no reliable and run-specific field-based test battery to examine the degree of lower limb asymmetry in distance runners. Therefore, this study aims to assess the test-retest, intra- and inter-rater reliability of a newly created running-specific field-based test battery to assess the presence and degree of functional lower limb asymmetry among novice, moderatly and highly trained distance runners as well as a control group of non-athletes. The second objective is to assess the association between inter-limb asymmetry and running performance.
