PG - 472-478 LID - 10.1097/PEP.0000000000000941 [doi] AB - PURPOSE: The purpose of this study was to standardize 1-repetition maximum (1-RM) testing procedures and evaluate the safety and feasibility of these procedures in youth with cerebral palsy (CP). METHODS: Youth with CP completed 1-RM testing on a leg press. RESULTS: Mean absolute, adjusted, and normalized 1-RM loads were 262.4 +/- 161.3 lb, 127.0 +/- 80.2 lb, and 1.28 +/- 0.51, respectively, and 67% were able to successfully lift the same or heavier load after a single failure. Cessation of testing after 1 failed attempt resulted in a 19.0% underestimation of the 1-RM. CONCLUSIONS: 1-RM testing in youth with CP is safe and feasible. Multiple attempts at a failed load should be provided to prevent underestimation in strength. The 1-RM test provides a more accurate strength assessment, which will improve the dosing for resistance training in youth with CP.
