If you’re a baseball player, you’re probably always looking for ways to throw harder while staying injury-free. Many pitchers focus primarily on their arm, but there’s a bigger picture to consider when it comes to increasing velocity and preventing injuries.
Recent research highlights the importance of pelvis and trunk rotation, as well as hip flexibility, in maximizing your pitching performance. Let’s break down how these factors work together to help you throw faster and keep your arm healthy.
How Pelvis and Trunk Rotation Increase Pitching Velocity
A recent study explored how different parts of the body contribute to pitching velocity. While much focus is given to arm mechanics, this research delved into the roles of the pelvis, trunk, and hips. Here’s what the study found:
Peak Trunk Velocity:
The speed at which your trunk rotates is one of the most significant predictors of your pitch velocity. It acts as the engine powering your arm. The faster your trunk rotates, the more energy is transferred through your arm to the ball, increasing pitch speed.
About 25% of pitch speed variation comes from how fast the trunk rotates (Reference: Matsuo, T., Escamilla, R.F., Fleisig, G.S., Barrentine, S.W., & Andrews, J.R. (2001). Comparison of Kinematic and Temporal Parameters Between Different Pitch Velocity Groups. Journal of Applied Biomechanics, 17(1), 1-13.).
Pelvis Rotation:
While the trunk plays a big role, pelvis rotation is also crucial. Proper timing and speed of pelvis rotation generate the torque needed for the trunk to accelerate, ultimately affecting how fast you throw.
The Importance of Hip Flexibility in Pitching Mechanics
In addition to pelvis and trunk rotation, hip flexibility is key for both pitching velocity and injury prevention. Research shows that greater flexibility, particularly in the lead hip’s internal rotation, directly impacts ball velocity.
For every 10° increase in hip rotation, pitchers can throw the ball 1-2 mph faster (Reference: Robb, A.J., Fleisig, G.S., Wilk, K.E., Macrina, L., & Andrews, J.R. (2010). Passive Range of Motion of the Hips and Their Relationship with Pitching Biomechanics and Ball Velocity in Professional Baseball Pitchers. The American Journal of Sports Medicine, 38(12), 2487-2493.).
However, with increased hip flexibility, the stress on the elbow (elbow varus moment) also rises. That’s why mastering timing and mechanics is essential for preventing elbow injuries.
How to Train Pelvis Velocity and Hip Flexibility to Prevent Arm Injuries
Here are some key strategies to help you improve pelvis velocity, trunk strength, and hip flexibility while minimizing injury risk:
Move Fast:
- Focus on increasing pelvis speed during exercises like medicine ball throws.
Core and Pelvic Strengthening:
- Build a strong foundation through core exercises that enhance your ability to move quickly.
Enhancing Hip Mobility:
- Exercises that create adaption to allow for greater hip internal rotation will provide long term benefits. These can include static stretches but should also incorporate some portion of active and dynamic movements to allow for the carry over.
Mechanical Drills:
- Drills that improve the connection between your hips and shoulders can help your pitching mechanics. Medball and banded drills can be examples of these.
Plyometric Exercises:
- Controlled plyometric drills mimic the quick, powerful movements of pitching and improve explosive power.
Monitor Mechanics:
- Check your movements with a coach often to move better and lessen strain on your elbow and shoulder.
Combining Mobility with Strength for Optimal Performance
Pitching is a full-body activity that requires coordination between your hips, trunk, and upper body. By focusing on improving pelvis and trunk rotation and enhancing hip flexibility, you can maximize pitching velocity while minimizing the risk of arm injuries. The key is creating a smooth, powerful, and efficient chain of motion that begins with the lower body and ends with a fast, healthy arm.

1. How can I increase my pitching velocity safely?
You can safely increase pitching velocity by improving your pelvis and trunk rotation, strengthening your core, and enhancing hip flexibility. These factors help generate more power and speed while reducing the strain on your arm.
2. Does hip flexibility really affect pitching velocity?
Yes, greater hip flexibility, particularly in the lead hip’s internal rotation, is linked to faster pitch speeds. Studies show that for every 10° increase in hip rotation, pitchers can gain an additional 1-2 mph on their throws.
3. How can I prevent arm injuries while increasing pitching speed?
Prevent arm injuries by focusing on full-body mechanics rather than just your arm. Strengthen your core, increase pelvis and trunk rotation speed, and practice proper throwing mechanics with the help of a coach.
4. What exercises can improve my pelvis rotation for pitching?
Exercises like medicine ball throws, core strengthening drills, and plyometric exercises can help improve pelvis rotation, leading to faster pitches.
5. Can poor pitching mechanics lead to injuries?
Yes, improper pitching mechanics can lead to elbow and shoulder injuries. It’s essential to focus on the efficiency of your movements and work with a coach to ensure proper form and timing.
