UNASSIGNED: The assessment of @entity121 ( @entity121 ) is common among strength and conditioning professionals as well as clinicians desiring to quantify baseline muscle performance and determine injury risk. Reference values for such assessments are documented in the literature; however, their utility may be of limited value due to heterogeneous @entity1 selection and limited demographic reporting. Moreover, active cohorts who engage in @entity3013 ( @entity3013 ) may reach a ceiling effect on existing reference values when testing routinely trained muscles. Thus, the purpose of this study was to establish reference values for standardized @entity121 tests among @entity1 who participate in recreational @entity3013 and to determine if imbalances or asymmetries exist. @entity1 included 61 @entity1 aged 18-59 who engaged in @entity3013 for at least one year. Flexor, extensor, and lateral flexor @entity121 was isometrically assessed using standardized procedures with documented reproducibility (r >=  0.93). Results identified significant differences (p < .001) between mean @entity121 times of flexors (163 +/-106 seconds) and extensors (105 +/-57 seconds). Left (66 +/-38 seconds) and right side bridge (61 +/-33 seconds) were comparable (p=0.06). Flexor to extensor imbalances were more pronounced among @entity3013 @entity1 when compared to previously reported general population reference values, suggesting a training effect or bias. Moreover, similar imbalances favoring the flexors are a documented risk factor for @entity1643 . Thus, training considerations inclusive of the extensors may benefit @entity1 who engage in @entity3013 as a means of mitigating risk. Individuals evaluating muscle performance should consider reference values that represent the population of interest.
