Figure 5. Individual changes (A), residuals in individual changes (B), and (C) coefficient of variations (CV) in mean group changes in maximal sprint speed (MSS) and change of direction (COD) in response to seven weeks of high-intensity interval training prescribed using anaerobic speed reserve (ASRHIIT), maximal aerobic speed (MASHIIT) and maximal exertion [i.e., sprint interval training (SIT)]. Circles indicate represent the group mean response. * Denotes significant difference vs. pre-training (p ≤ 0.05). † Significantly lower than MASHIIT group (p ≤ 0.05). ⁑ Significantly greater than MASHIIT. ‡ Significantly greater than MASASR.
