The Effect of upper Extremity Proprioception on Technical Performance in Handball players

Area of Science:

• Sports Science
• Biomechanics
• Human Motor Control

Background:

• Proprioception, the sense of joint position and movement, is crucial for athletic performance.
• Understanding the specific effects of upper extremity proprioception on handball-specific skills is essential for targeted training.
• Previous research has indicated a general link between proprioception and motor skills, but specific impacts on handball free throws require further investigation.

Purpose of the Study:

• To investigate the impact of upper extremity proprioception on free throw accuracy, speed, and reaction speed in professional male handball players.
• To quantify the relationship between proprioceptive sensory acuity in various shoulder and elbow movements and handball throwing performance metrics.

Main Methods:

• Fifteen professional male handball players participated in the study.
• Proprioception was measured using a goniometer.
• Reaction speed was assessed via a light trainer system, and free throw speed was measured using a sport radar.
• Linear regression analysis was employed to determine the effect of proprioception on performance variables.

Main Results:

• Increased proprioceptive sensory acuity in shoulder flexion, extension, external rotation, and elbow flexion/extension demonstrated significant positive correlations with improved free throw speed, accuracy, and reaction speed (R² values ranging from 0.270 to 0.873; p<0.05).
• Shoulder internal rotation proprioception positively influenced free throw accuracy and reaction speed (R² values between 0.338 and 0.415; p<0.05), but not free throw speed (p>0.05).
• The findings indicate a strong link between enhanced proprioceptive acuity and superior performance in key handball throwing actions.

Conclusions:

• Higher proprioceptive acuity in the upper extremity enhances joint motor control, directly contributing to improved athletic performance in handball players.
• Targeted training to improve proprioceptive sense may enhance technical skills, leading to better score performance.
• The study highlights the importance of proprioception as a trainable factor for optimizing handball throwing efficiency and overall game success.
