Accelerated Muscle Recovery in Baseball Pitchers Using Phase Change Material Cooling

Area of Science:

• Sports Medicine
• Orthopedics
• Exercise Physiology

Background:

• Pitching performances in baseball can lead to impairments in muscle function.
• Recovery strategies for pitchers are crucial for maintaining performance and preventing injury.
• The efficacy of localized cryotherapy for post-pitching recovery is not well-documented.

Purpose of the Study:

• To document muscle function recovery after a pitching performance.
• To determine if prolonged postgame phase change material (PCM) cooling of the shoulder and forearm accelerates recovery in college baseball pitchers.

Main Methods:

• Sixteen college pitchers participated in the study.
• Pitchers were randomized to receive either postgame PCM cooling packs (15°C for 3 hours) on the shoulder and forearm or no cooling (control group).
• Muscle strength (shoulder internal rotation, external rotation, grip) and serum creatine kinase (CK) activity were assessed before and two days after pitching.

Main Results:

• Pitchers receiving PCM cooling showed significantly higher shoulder internal rotation and grip strength compared to the control group.
• One day post-pitching, internal rotation strength was 95% of baseline with PCM cooling versus 83% for control.
• Grip strength was 107% of baseline with PCM cooling versus 95% for control; soreness and CK levels were not significantly different between groups.

Conclusions:

• This study provides evidence of muscle function impairments following baseball pitching.
• Prolonged postgame PCM cooling of the shoulder and forearm accelerates the recovery of muscle strength in baseball pitchers.
• This cryotherapy intervention represents a novel approach to enhance post-game recovery for pitchers.
