Figure 2.

Time course (with example error bars) of post-activation potentiation (PAP) measured as the torque evoked during a twitch contraction (T_Tw) versus post-activation performance enhancement (PAPE) measured as the torque produced during a voluntary contraction (T_Vol). PAP and PAPE exhibit different temporal profiles, suggesting that they are at least partly different phenomena. Data for illustrative purposes only; experimental data can be seen in Seitz et al. (2015); gray solid line indicates that PAP would be higher at time points < 1 min (>80% according to Hamada et al., 2000). Note: functions are plotted from 1 min because the first experimental data were collected at this time point.
