Figure 2. Schematic diagram of the PAP (A), PAPEV (B), and PAPEE (C) protocols. Interventions started with baseline testing, followed by a conditioning contraction and further testing trials at 2s, 4min, 8min, and 12min after the conditioning contraction. The conditioning contraction (CC) for the PAP trial was a MVIC for 10s. For the PAPEV trial, it was a voluntary contraction at 80% of the MVIC that lasted 6s, and for the PAPEE trial, it was an electrical contraction at 80% of the MVIC, also lasting 6s. Note: The CC for both PAPE conditions was done three times with a break of 2 minutes in between.
