Changing Body Movement Patterns in 9-Year-Old Baseball Pitchers: A Pilot Study.

Area of Science:

• Biomechanics of throwing
• Youth sports medicine
• Injury prevention in athletes

Background:

• Increasing incidence of arm injuries in throwing athletes.
• Potential link between inefficient movement patterns and injuries in young baseball players.
• Uncertainty regarding the modifiability of these patterns in youth.

Purpose of the Study:

• To assess the impact of a novel 21-day throwing program on youth baseball players' movement patterns.
• To determine if common, practical tools can effectively measure these changes.
• Hypothesis: The program would alter movement patterns in a short timeframe.

Main Methods:

• Descriptive laboratory study involving ten 9-year-old baseball athletes.
• A 21-day throwing program designed to reduce movement inefficiencies.
• Pre- and post-program video and radar evaluations of throwing mechanics and velocity.

Main Results:

• Significant decreases observed in throwing arm antecubital and humerothoracic angles, and back leg minimum popliteal angle.
• Mean decreases of 35°, 10°, and 8° respectively.
• Increased throwing velocity (mean 2.6 mph) correlated with decreased back leg popliteal angles.

Conclusions:

• Young baseball players can rapidly adapt and modify their movement patterns through targeted training.
• The developed throwing program shows potential for enhancing injury prevention and treatment strategies.
• Identification of improved movement patterns may aid in managing and preventing youth baseball injuries.
