Brief 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.

Conditions

Performance; Post Activation Potentiation; Soccer

Keywords

Soccer; Post activation Performance Enhancement; Dynamic Contraction; Isometric contraction

Outcome Measures

Primary Outcomes (3)

• Significant difference in dynamic condition

  It is expected that there will be a significant difference in the rate of change of direction during different rest periods in the dynamic contraction condition compared to the isometric contraction condition

  From baseline to the end of measurement at 1 weeks

• Significant difference in isometric condition

  It is expected that there would be a significant difference in the rate of direction change during different rest periods in the isometric contraction condition compared to the dynamic contraction condition.

  From baseline to the end of measurement at 1 weeks

• The time between the conditions is different

  Compared to the first measurement, a change in the rate of directional change in conditions is expected.

  From baseline to the end of measurement at 1 weeks.

Study Arms (2)

Dynamic PAPE

EXPERIMENTAL

In this protocol, the load determined for footballers during knee extension will be applied as 90% of their one repetition maximum (1TM). After the 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.

Other: Dynamic PAPE

Isometric PAPE

EXPERIMENTAL

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 only the lever arm with 1TM 90% load, 2 minutes rest will be applied between sets.

Other: Isometric PAPE

Interventions

Dynamic PAPE OTHER

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.
