Table 2: Spearman’s correlations between absolute and relative strength as measured by the 5RM WL with percent potentiation of the 0-5 m, 0-10 m, and 0-20 m intervals in a 20-m sprint at ~15 s-16 min post 5RM WL performance. A negative correlation indicates a higher load was associated with a faster time.
