Notes:
F0, theoretical maximal force; v0, theoretical maximal velocity; Pmax, theoretical maximal power; LL, low level or amateur; ML, medium level or semi-professional; HL, high level or professional; EL, elite level or international. Significant correlations (highlighted in bold): *P < 0.05, **P < 0.01, ***P < 0.001. Qualitative interpretations of the Pearson’s correlations coefficients: trivial (r < 0.1), small (r = 0.1–0.3), moderate (r = 0.3–0.5), large (r = 0.5–0.7), very large (r = 0.7–0.9), and nearly perfect (r > 0.9) (Hopkins et al., 2009).
