Brief summary

The aim of this study is to examine the relationship between injury risk and pain, fatigue, muscle strength, balance and quality of life in volleyball players. In this context, it will be investigated how the pain and fatigue levels experienced by volleyball players interact with muscle strength and balance and how these factors increase the risk of injury.

Detailed description

Musculoskeletal injuries are highly prevalent among volleyball players and this may be due to the interaction of various physical and subjective factors. Although some risk factors such as muscle strength and balance have been previously investigated, there is limited data on how these parameters together relate to injury risk and athlete health. In this cross-sectional study, standardized tests and self-report questionnaires will be administered to a sample of competitive volleyball players.

Interventions

OTHERPhysical evaluations in Volleyball Players

This study will evaluate pain, fatigue, muscle strength, balance and quality of life in volleyball players. All these measurements will be completed in two sessions lasting 45-60 minutes.

Design outcomes

Primary

MeasureTime frameDescription
Injury risc assessmentthrough study completion, an average of 1 yearThe Functional Movement Screening Test will be used to assess injury risc in athletes. Seven exercises are used in this test. Each movement is scored on a scale from 0 to 3, with a maximum total score of 21. As the score from this test increases, the risk of injury decreases.

Secondary

MeasureTime frameDescription
Pain intensity evaluationthrough study completion, an average of 1 yearPain intensity will be assessed using the Numerical Rating Scale, where participants rate their pain intensity from 0 (no pain) to 10 (maximum pain).
Fatigue assessmentthrough study completion, an average of 1 yearThe Perceived Physical and Cognitive Fatigue Scale will be used to assess athletes' physical and cognitive fatigue. The scale has 19 items, scored ranging from 19 to 95. Higher scores indicate increased perceived fatigue levels.
Forced vital capacity (FVC)through study completion, an average of 1 yearForced vital capacity (FVC) will be evaluated with a spirometer.
Forced expiratory volume in the first second (FEV1)through study completion, an average of 1 yearForced expiratory volume in the first second (FEV1) will be evaluated with a spirometer.
FEV1/FVCthrough study completion, an average of 1 yearFEV1/FVC will be evaluated with a spirometer.
Flow rate 25-75% of forced expiratory volume (FEF 25-75%)through study completion, an average of 1 yearFlow rate 25-75% of forced expiratory volume (FEF 25-75%)) will be evaluated with a spirometer.
Peak flow rate (PEF)through study completion, an average of 1 yearPeak flow rate (PEF) will be evaluated with a spirometer.
Muscle Strength Measurementthrough study completion, an average of 1 yearThe lower extremity muscle strength of athletes will be assessed using isokinetic test. Each maximal voluntary contraction will involve the athlete contracting as hard and as fast as possible from full extension to full flexion.Higher values indicate better muscle strength.
Hand Grip Strength measurementthrough study completion, an average of 1 yearHand grip strength will be assessed using a hand dynamometer. Participants will perform three trials on each hand . The maximum grip strength value for each hand will be analysed.
Respiratory Muscle Strength measurementthrough study completion, an average of 1 yearRespiratory muscle strength will be evaluated using a spirometer. Athletes will perform maximal inspiration (Müller maneuver) and expiration (Valsalva maneuver) to obtain measurements. The highest value will be used for analysis.
Cough force measurementthrough study completion, an average of 1 yearCough force will be assessed using a peak flow meter. The highest value of three attempts will be recorded. The high value obtained indicates good cough strength.
Balance evaluationthrough study completion, an average of 1 yearBalance will be assessed using the Y-Balance Test, and the average distance reached will be recorded.
Quality of Life (SF-36 or WHOQOL-BREF)through study completion, an average of 1 yearThe Short Form-36 (SF-36) will be used to assess quality of life. total score is scored from 0 (poorest health) to 100 (best health), with higher scores indicating better health status.
