Brief Summary

This study investigates the architecture, muscle strength, and performance of skeletal muscles. Skeletal muscles constitute a mass of muscle fascicles connected to bones via tendons. Muscle architecture is defined as the geometric arrangement of muscle fiber bundles in relation to the axis that generates force. This arrangement influences the muscle's contraction speed, force generation capacity, and range of motion. Ultrasonography is a method for examining muscle morphology without radiation exposure. The architectural features of muscles have been a proven method for evaluating and enhancing muscle function. The purpose of this study is to examine the effects of eight weeks of eccentric exercises on the right and left triceps surae muscles in young volleyball players. This investigation aims to contribute to the literature concerning muscle architecture. The study will be conducted using statistical analysis and the SPSS program. The study has obtained ethical approval and will be conducted at Istanbul Medipol University. Thirty healthy young volleyball players will be involved in this research. The participants' muscle architecture, strength, and performance will be measured. Additionally, the impact of eccentric exercises will be examined, and statistical data analysis will be carried out. Ultimately, this study aims to explore the effects of eccentric exercise on the muscle architecture and performance of young volleyball players, aiming to contribute to the literature by understanding and enhancing muscle function and performance.

Outcome Measures

Primary Outcomes (6)

• Muscle Architecture- muscle thickness

  Muscle architecture of the gastrocnemius medialis, lateralis, and soleus muscles are visualized by the USG device. Their muscle thickness (mm) is measured and recorded.

  5 months

• Muscle Architecture- fiber length

  Muscle architecture of the gastrocnemius medialis, lateralis and soleus muscles are visualized by the USG device. Their fiber length (mm) is measured and recorded.

  5 months

• Muscle Architecture- pennation angle (degree)

  Muscle architecture of the gastrocnemius medialis, lateralis and soleus muscles are visualized by the USG device. Their pennation angle (degree) is measured and recorded.

  5 months

• Performance measurement- Single-leg hop test

  Single-leg hop tests are implemented. Right and left hop results are recorded in cm.

  5 months

• Performance measurement- vertical jump tests

  Vertical jump tests are implemented. Results are recorded in cm.

  5 months

• Muscle force measurement

  The strength of the gastrocnemius medialis, lateralis and soleus muscles is measured and recorded in Newtons.

  5 months

Study Arms (2)

Exercise Group (EG)

EXPERIMENTAL

Exercise Group (EG) is the first arm of the study in which volleyball athlete participants performed eccentric exercises in addition to their exercise routines.

Behavioral: Eccentric Exercise

Control Group (CG)

NO INTERVENTION

Control Group (CG) is the second arm of the study, where volleyball athletes only continued their exercise routines and no external intervention was made.

Interventions

Eccentric Exercise BEHAVIORAL

It was investigated whether volleyball athlete participants would develop muscle architecture, muscle strength and performance parameters differently from the control group by performing eccentric exercises in addition to their exercise routines.
