Post-activation Performance Enhancement in Soccer Players:
Sponsor: Karabuk University
Summary
This study will be conducted in a randomised, crossover design. Soccer players will participate in two test sessions 48 hours apart. The athletes will be pre-tested in the professional direction change test and after the PAPE protocol of the group they are included in is applied, they will be taken to the professional direction change test at 15th second, 3rd, 6th, 9th and 12th minutes.

Interventions
Dynamic PAPE
In this protocol, the load determined for footballers during knee extension will be applied as 90% of their one repetition maximum (1TM). After a standard warm-up session at the beginning, the protocol will be performed by performing 1 set of 3 repetitions with the previously determined 1TM 90% load without resting between repetitions. Isometric knee extension exercise will be used in the protocol. The movement will be performed sitting, in a position suitable for limb lengths and in a controlled manner using a leg extension machine. At the beginning of the movement, the knees will be flexed 90° and the adjustable lever arm of the machine will be fixed at this angle. Then they will be asked to perform bilateral isometric knee extension until the knees form a 180° angle. They will also be verbally motivated to complete the knee extension exercise.
Isometric PAPE
Isometric contraction will be used in the protocol. On the leg extension machine, the protocol will be performed by applying 3 sets of 3 seconds against the lever arm only with 1TM 90% load, 2 minutes rest will be applied between sets. Isometric knee extension exercise will be used in the protocol. The movement will be performed sitting, in a position suitable for limb lengths and in a controlled manner using a leg extension machine. At the beginning of the movement, the knees will be flexed 90° and the adjustable lever arm of the machine will be fixed at this angle. Then they will be asked to perform bilateral isometric knee extension until the knees form a 180° angle. They will also be verbally motivated to complete the knee extension exercise.
