When comparing the OFE-SLP with SLP and the OFE-SLP with BIOFIT-LP, a significantly lower activation was found in the OFE-SLP for all muscle groups, in the full stroke, concentric, and eccentric phases (ES = 0.2-0.5 effect size between small and moderate; \(p\) < 0.01-0.001), except for the tibialis anterior, as compared to SLP for the full stroke and eccentric phase (ES = 0.14-0.5; effect size between small and moderate; \(p\) > 0.05); for the gastrocnemius, as compared to BIOFIT-LP for the full stroke, concentric phase, and eccentric phase (ES = 0.2-0.9; effect size between small and moderate; \(p\) > 0.05); and for the gastrocnemius as compared to SLP at 60% 1 RM in the eccentric phase (ES = 0.25; small effect size; \(p\) > 0.05); and for the gastrocnemius as compared to SLP at 60% 1 RM in the eccentric phase (ES = 0.25; small effect size; \(p\) > 0.05). \begin{table}
