英文摘要 | Baseball pitchers are at risk for elbow and shoulder injuries. It is believed that many arm injuries in baseball pitchers result from cumulative microtrauma. The aim of this study was to investigate skeletal muscle damage after real games in Division I collegiate starting and relief pitchers. In order to examine the potential accumulation of muscle damage, the same procedure was performed in the beginning and end of a 3-month tournament. The first study included 4 starting pitchers and 5 relief pitchers. The second study included 3 starting pitchers and 5 relief pitchers. Plasma samples were collected the day before and 0 min, 30 min, 24 hr, 3 days, and 4 days after pitching a real game. For starting pitchers, plasma LDH was significantly increased immediately after pitching in the first study, and immediately and 30 min after in the second study. Plasma CK was significantly elevated immediately and 30 min after in the second study. For relief pitchers, LDH was significantly higher immediately after pitching in the second study. Plasma CK was unchanged in both studies. The pitching-induced muscle damage was similar between the 2 studies in both starting and relief pitchers. The results of this study indicated that starting pitchers may suffer the skeletal muscle damage after pitching a real game. However, the muscle damage appeared to be fully recovered within 24 hr. On the other hand, there was no significant muscle damage after pitching a real game in relief pitchers. In addition, a 3-month season did not result in accumulation of muscle damage in collegiate pitchers. |
