About this study
Official title: The Effect of Core Muscle Strengthening Training on Performance in Soccer Players
The core region is a part of the body composed of axes surrounding the torso and plays a crucial role in maintaining stability. Therefore, it is considered important for maintaining athletic performance in athletes. This study aims to investigate the effects of core strength training, in addition to routine training programs, on jumping, agility, speed, balance, and shooting speed performance in amateur football players.
Read the detailed description
The core region, consisting of muscles that surround the torso, plays a crucial role in maintaining stability in the body. Therefore, it is considered essential for maintaining athletic performance in athletes. It is known that the core region is activated before extremity movements in achieving athletic performance. For this reason, core training plays an important role in maintaining optimal extremity movement and improving performance. Furthermore, the importance of core stabilization in preventing injuries is emphasized. Although various studies have been conducted on the importance of core training in athletes, the lack of standardization still makes this issue significant. In this context, this study aims to examine the effect of core strength training, in addition to routine training programs, on jumping, agility, speed, balance, and shooting speed performance in amateur football players.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Core trainingOther
The core training group will receive progressive exercises designed to strengthen core muscles, 3 days a week for 8 weeks.
ControlOther
The control group will continue with their routine training programs.
| Study group | Role | What they receive |
|---|---|---|
| Core training group | Experimental | The core training group will receive progressive exercises designed to strengthen core muscles, 3 days a week for 8 weeks. Receives: Other: Core training |
| Control Group | Other | The control group will continue with their routine training programs. Receives: Other: Control |
What is being measured
The primary outcome is the main question the study is designed to answer.
Jumping performance
A mobile application compatible with the My Jump video camera system will be used to measure participants' vertical jump heights.
Measured: Baseline, After intervention (eight week later)
Balance performance
Participants' dynamic balance will be assessed using the modified Star Excursion Balance Test (SEBT). Measurements will be taken in three directions: anterior, posteromedial, and posterolateral. The better the reach, the better the balance performance.
Measured: Baseline, After intervention (eight week later)
Agility
Agility will be assessed using the T-shaped agility test, which consists of four cones. Agility increases as the time decreases.
Measured: Baseline, After intervention (eight week later)
Speed
The 20-meter speed test will be used to determine the athlete's speed. Measurements will be taken using photocells placed at the beginning and end of the 20-meter running distance.
Measured: Baseline, After intervention (eight week later)
Core endurance
For core endurance testing, trunk extensor endurance (Sorenson test), trunk flexor endurance, and trunk oblique muscle endurance tests will be performed.
Measured: Baseline, After intervention (eight week later)
