• Conditions: Performance; Post Activation Potentiation; Soccer

• Registration Number: NCT06875505
• Lead Sponsor: Karabuk University

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.

Detailed Description

This study will be conducted in a randomised, crossover design. Subjects will participate in two test sessions 48 hours apart. To eliminate the effect of fatigue, participants will be warned not to engage in intense physical activity before the study days and to pay attention to adequate carbohydrate intake so that repeated sprint performance will not be affected. On the 1st day of the study, after the participants were informed about the study, their heights will be recorded with a height meter, and their weights and body fat percentages will be taken with the Inbody 270 device. After the descriptive characteristics of all participants are obtained, the warm-up protocol will be applied and 1 RM will be determined and recorded by performing knee extension movement on the Knee Extension device. On the second day of the study, all athletes will be pre-tested in the professional change of direction test and will be taken to the professional change of direction test at 15 seconds, 3 minutes, 6 minutes, 9 minutes and 12 minutes after the PAPE protocol of the group they are included in is applied. On the third day of the study, the pre-tests of all athletes in the professional direction change test will be taken again and they will be taken to the professional direction change test at 15 seconds, 3rd, 6th, 9th and 12th minutes after the PAPE protocol of the group they are included in is applied. Participants will be asked to stop eating 1.5 hours before the measurement time. Athletes will be allowed to drink water (500ml) during the test and will be verbally motivated during the professional change of direction test.

Primary Outcome Measures

Name	Time	Method
Significant difference in dynamic condition	From baseline to the end of measurement at 1 weeks	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
The time between the conditions is different	From baseline to the end of measurement at 1 weeks.	Compared to the first measurement, a change in the rate of directional change in conditions is expected.
Significant difference in isometric condition	From baseline to the end of measurement at 1 weeks	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.
