Purpose: This study was designed to compare pitching performance (velocity, accuracy), symptomology and functional movement across three recovery techniques (active recovery (pedaling on a stationary bike at 40% Max Age Predicted Heart Rate), passive recovery (sitting down with a jacket around the pitchers arm), and Electro muscular stimulation (sitting down with stim placed on the pitchers arm at the anterior and posterior deltoid) in NCAA Division II collegiate pitchers. Methods: Eight male Division II collegiate baseball athletes (Age: 20.1 ± 1.7 years, Mass: 84.8 ± 10.9 kg, average years of experience: 1.8 ± 1.3, % fat mass: 11.1 ± 4.9, Starter pitcher/relief pitcher: 4/4) volunteered to participate in this study. Each pitcher threw 15 pitchers per inning for a total of 45 pitches per session (3 Fastball, 1 Curveball, 1 Changeup-3 times per inning). After each inning pitched a recovery was performed for 6 minutes to simulate the time in between innings. Prior to warm up, after warm up and after each of the three innings was performed each pitcher was tested for HLa, delta pain scale, internal rotation, external rotation, overall RPE and local RPE. Results: The electro muscular stimulation showed significantly greater amount of strikes thrown at p < 0.05. Overall the velocities (mph) were similar over all three recovery methods and all three innings thrown. Conclusion: Findings from this study suggest the importance of possibly implementing the use of electro muscular stimulation during pitchers recoveries times between innings. Since the velocity was not affected, different recovery methods may be useful to aid the accuracy of different individuals in game situations.
