Pitching with weighted balls is a training method that has gained popularity for its potential to increase pitching velocity. However, the use of these balls requires careful consideration due to the complexities involved in their impact on pitching mechanics and the potential risks.
Key Findings and Considerations:
Mechanics and Velocity:
Weighted balls have been shown to influence pitching mechanics. A study by Driveline Baseball revealed that arm kinematics, like elbow flexion and shoulder rotation, are significantly affected by ball weight. Different weights can alter the pitcher's arm position and movement, potentially affecting pitching effectiveness and safety.
A 6-week training program with weighted balls resulted in a 3.3% increase in pitch velocity for some participants, but not for all. Interestingly, 8% showed no change, and 12% experienced a decrease in pitch velocity.
Injury Risks:
There is a notable injury risk associated with weighted ball programs. The same study by Mike Reinold mentioned earlier reported a 24% injury rate among participants using weighted balls, with injuries occurring both during the study and in the following season.
MLB.com also highlights the increased risk of injury with weighted ball programs, emphasizing the importance of integrating these tools into a comprehensive pitcher training program rather than relying on them as a shortcut to increased velocity.
Proper Technique and Age Considerations:
Using weighted baseballs requires proper technique and a well-designed training regime. It’s recommended that players start using weighted baseballs around the age of 16, when the body is more anatomically developed.
It's crucial for pitchers to have their technique evaluated by a coach or pitching expert before incorporating weighted balls into their training. This ensures that they are using the correct angle and technique for each pitch.
Balancing Training:
A balanced approach to training is recommended. This involves not only using weighted balls but also incorporating other elements like strength and conditioning, proper nutrition, and overall body mechanics. As outlined by MLB.com, exercises should focus on total-body strength and quality movement patterns, crucial for pitching performance.
In conclusion, while weighted balls can be a valuable tool for improving pitching velocity, their use should be balanced and carefully integrated into a broader training program. It's essential to prioritize proper technique, age-appropriate training, and awareness of the injury risks. Coaches and trainers should tailor programs to individual athletes, considering these factors to maximize benefits while minimizing risks.
