Eleven experienced powerlifters with cerebral palsy (CP) and seven with other movement disorders (OTH) undertook a 6-week high-velocity strength training intervention (HVST). A repeated power ability (RPA) test was conducted one week before (T1) and one week after (T2) the 6-week training program. In RPA test, athletes performed the maximum number of repetition possible within 5 sets of 15 s each, with a 1-min passive recovery between sets. We calculated the total weight (TW) pressed during the test and the weight pressed in the first 5 s (5sW) of all sets.
