Brief Summary

Although the effectiveness of motor imagery in improving performance in sports is known, there is no research on its preventive role against injuries. the primary aim of this study is to investigate the effect of motor imagery on improving risk factors related to jumps and falls in volleyball players. The secondary aim of this study is to investigate the effect of motor imagery on cortical functions.

Outcome Measures

Primary Outcomes (10)

  • Kinematic Analysis: Change in Hip Flexion During Initial Contact. Baseline and 12 Weeks

    The flexion angles of the hip, knee, and dorsiflexion of the ankle during jumping and landing will evaluated with the 'Dartfish Analysis System' as degree.This software possesses simultaneous recording and measurement capabilities and is compatible with mobile phones for installation. This software is employed as a clinical instrument to measure movement amplitude and velocity, biaxial spatial coordinates, and joint angles throughout movement in the volleyball players. Unilateral measurements were used. During video recording, athletes turned to their left sides, and measurements were taken from the left side. The study aimed to report a change from the baseline value.

Study Arms (3)

solo training

EXPERIMENTAL

Prior to the study, a video recording with the correct jump and landing kinematics, showing the correct hip, knee, and ankle flexion angles , will be recorded by the researchers. The video will be a minute long, consisting of front and side angles, and featured a professional volleyball player who won't be included in the study. Players in solo training group individually underwent the training.For standardization purposes, no questions will allowed during the training session. In the training session, players will be asked to watch the correct landing video at a slightly slower speed and contemplate the appropriate hip, knee, and ankle angles. Then, the researcher explained correct landing mechanics, while referring to the correct landing video, pointed out the common errors, and described how to correct them.The researcher then will explain to the players what MI is and how it works.

Other: motor imagery

group training

EXPERIMENTAL

Prior to the study, a video recording with the correct jump and landing kinematics, showing the correct hip, knee, and ankle flexion angles, will be recorded by the researchers. The video will be a minute long, consisting of front and side angles, and featured a professional volleyball player who will not included in the study. Players in the GT group underwent the training as a group in a quiet, climate-controlled room. For standardization purposes, no questions were allowed during the training session. In the training session, players were asked to watch the correct landing video at a slightly slower speed and contemplate the appropriate hip, knee, and ankle angles. Then, the researcher explained correct landing mechanics, while referring to the correct landing video, pointed out the common errors, and described how to correct them.The researcher then will explain to the players what MI is and how it works.

Other: motor imagery

control training

NO INTERVENTION

Players only participate in evaluations

Interventions

The researcher will explain to the players what MI is and how it works. Following the explanation, players will seated in a comfortable armchair facing the researcher, will ask to minimize distracting thoughts, and to be as mindful as possible without speaking for five minutes, and to imagine themselves executing the correct angles during a landing.
