Szymanski，DJ，Beiser，EJ，Bassett，KE，Till，ME，Medlin，GL，Beam，JR，and DeRenne，C.不同暖身器材对大专棒球选手球棒速度之影响。J Strength Cond Res 25（2）：287-292，2011-棒球运动员可以在击球前使用各种热身设备。过去的棒球研究评估热身设备表明，实施是±12%的标准比赛蝙蝠重量产生最大的蝙蝠速度为高中和校际球员。本研究的目的是探讨各种热身装置对大专棒球运动员球棒速度（BV）的影响。22名I组校际棒球运动员（年龄= 20.0 ± 1.5岁，身高= 182.6 ± 8.3 cm，体重= 91.4 ± 11.4 kg，瘦体重= 78.8 ± 8.9 kg，%体脂= 13.6 ± 3.8）在不同的日子使用10种加重器械中的一种进行热身。10个测试阶段中的每一个包括标准化热身、用指定的热身装置尽可能用力的3次干挥杆、用标准比赛棒球棒的2次舒适的干挥杆，随后是3次比赛挥杆（挥杆之间休息20秒），同时用相同的标准比赛棒球棒从击球座上击球。结果表明，在使用10种预热装置中的任何一种后，BV均无统计学显著差异。对于男性校际棒球运动员，结果表明，热身设备从623.7到2721.5克（22-96盎司）不等。没有改变标准比赛棒球棒的平均BV，这表明校际球员可以使用甲板上的10个热身设备中的任何一个，并保持他们的BV。因此，建议您根据个人喜好选择在甲板圈中使用哪种热身工具。
Szymanski, DJ, Beiser, EJ, Bassett, KE, Till, ME, Medlin, GL, Beam, JR, and DeRenne, C. Effect of various warm-up devices on bat velocity of intercollegiate baseball players. J Strength Cond Res 25(2): 287-292, 2011-A variety of warm-up devices are available to baseball players to use before their game at-bat. Past baseball research evaluating warm-up devices indicates that implements that are ±12% of standard game bat weight produce the greatest bat velocities for high school and intercollegiate players. The purpose of this study was to examine the effect of various warm-up devices on bat velocity (BV) of intercollegiate baseball players. Twenty-two Division I intercollegiate baseball players (age = 20.0 ± 1.5 years, height = 182.6 ± 8.3 cm, body mass = 91.4 ± 11.4 kg, lean body mass = 78.8 ± 8.9 kg, % body fat = 13.6 ± 3.8) participated in a warm-up with 1 of 10 weighted devices on separate days. Each of the 10 testing sessions consisted of a standardized warm-up, 3 dry swings as hard as possible with the assigned warm-up device, 2 comfortable dry swings with a standard game baseball bat followed by 3 game swings (20-second rest between swings) while hitting a baseball off of a batting tee with the same standard game baseball bat. Results indicated that there were no statistically significant differences in BV after using any of the 10 warm-up devices. For male intercollegiate baseball players, results indicate that warm-up devices varying from 623.7 to 2,721.5 g (22-96 oz.) did not change mean BV of a standard game baseball bat, suggesting that intercollegiate players can use any of the 10 warm-up devices in the on-deck circle and maintain their BV. Therefore, personal preference as to which warm-up implement to use in the on-deck circle is advised.
