Potteiger, J. A., Blessing, D. L., & Wilson, G. D. (1992). Effects of varying recovery periods on muscle enzymes, soreness, and performance in baseball pitchers. Journal of Athletic Training, 27, 27-31.

The effects of varied recovery times on serum creatine kinase (CK), serum lactate dehydrogenase (LDH), muscle soreness, and pitch velocity in baseball pitchers (N = 10) were investigated. After 18 days of training, Ss pitched three simulated games. Four days of rest separated games A and B, and two days separated B and C. Measurements were taken before, immediately after, and 6, 24, 48, and 72 hours post-game.

CK was elevated and similar immediately after each game. LDH was also elevated but was reduced across the period of the three games. Muscle soreness was highest immediately after all games. Pitch velocity was similar in all games.

The amount of time, two or four days, did not affect any of the measures.

Implication. A two- and four-day between-baseball-games recovery period did not affect any of the recovery parameters measured in this study.
