Gadomski, SJ, Ratamess, NA, and Cutrufello, PT. Range of motion adaptations in powerlifters. J Strength Cond Res 32(11): 3020–3028, 2018—The aim of this study was to investigate range of motion (ROM) and training patterns in powerlifters. Upper- and lower-extremity passive ROMs were assessed through goniometry in 15 male powerlifters (35.3 ± 13.7 years) and 15 age-matched controls (34.9 ± 14.6 years). The Apley scratch test and modified Thomas test were used to assess ROM across multiple joints. Training frequency, stretching frequency, and exercise selection were recorded using questionnaires. Passive glenohumeral (GH) extension, internal rotation, and external rotation ROM were significantly decreased in powerlifters (p < 0.050). Powerlifters displayed decreased ROM in the Apley scratch test in both dominant (p = 0.015) and nondominant (p = 0.025) arms. However, knee extension angle was markedly improved in powerlifters (20.3 ± 7.3°) compared with controls (29.9 ± 6.2°; p < 0.001). Bench press and bench press variations accounted for 74.8% of all upper-body exercises, whereas back squat and deadlift accounted for 79.7% of all lower-body exercises in powerlifters' training programs. To determine whether existing ROM adaptations were seen in elite powerlifters, the powerlifting cohort was split into 3 groups based on Wilks score: <400 (low), 400–500 (intermediate), and >500 (high). GH ROM limitations were more pronounced in elite powerlifters (Wilks >500), who had more powerlifting experience (p = 0.048) and greater lean body mass (p = 0.040). Overall, powerlifters displayed decreased GH ROM, but increased hamstring ROM, after training programs that were heavily focused on the bench press, back squat, and deadlift.
