Numerous warm-up devices are available for use by softball players while they are in the on-deck circle. It is difficult to know which warm-up device produces the greatest bat velocity (BV) in the batter's box for softball players because on-deck studies with these individuals are sparse. Because the majority of warm-up device research has been conducted with baseball players, the primary purpose of this study was to examine the effect of various warm-up devices on the BV of female intercollegiate softball players and compare the results with those of male baseball players. A secondary purpose was to evaluate 2 new commercially available resistance devices as warm-up aids. Nineteen Division I intercollegiate softball players (age = 19.8 ± 1.2 years, height = 167.0 ± 4.7 cm, body mass = 69.2 ± 8.6 kg, lean body mass = 49.6 ± 3.6 kg, % body fat = 27.9 ± 5.9) participated in a warm-up with 1 of 8 resistance devices on separate days. Each of the 8 testing sessions had players perform a standardized dynamic warm-up, 3 maximal dry swings mimicking their normal game swing with the assigned warm-up device, 2 comfortable dry swings with a standard 83.8-cm, 652-g (33-in., 23-oz) softball bat followed by 3 maximal game swings (20-second rest between swings) while hitting a softball off a batting tee with the same standard softball bat. Results indicated that there were no statistically significant differences in BV after using any of the 8 warm-up devices (510.3-2,721.5 g or 18-96 oz) similar to in previous baseball research. This indicates that the results for both male and female intercollegiate players are similar and that intercollegiate softball players can use any of the 8 warm-up devices in the on-deck circle and have similar BVs. However, similar to in other previous baseball research, it is not recommended that female intercollegiate softball players warm up with the popular commercial donut ring in the on-deck circle because it produced the slowest BV.
许多热身设备可供垒球运动员在预备区使用。然而，由于针对预备区运动员的研究较少，很难确定哪种热身设备能使垒球运动员在击球区内产生最大的球棒速度 (BV)。由于大多数热身设备的研究都是针对棒球运动员进行的，因此本研究的主要目的是检查各种热身设备对女性大学垒球运动员 BV 的影响，并将结果与男性棒球运动员进行比较。次要目的是评估两种新的商业上可用的阻力设备作为热身辅助设备。19 名一级大学垒球运动员（年龄=19.8±1.2 岁，身高=167.0±4.7cm，体重=69.2±8.6kg，瘦体重=49.6±3.6kg，体脂%=27.9±5.9）在不同的日子里使用 8 种阻力设备中的 1 种进行热身。在 8 次测试中，每次测试都让运动员进行标准化的动态热身，用指定的热身设备进行 3 次最大的干挥棒模拟他们正常的比赛挥棒，然后用标准的 83.8cm、652g（33 英寸、23 盎司）垒球棒进行 2 次舒适的干挥棒，接着进行 3 次最大的比赛挥棒（两次挥棒之间休息 20 秒），用同样的标准垒球棒击打击球台上的垒球。结果表明，在使用 8 种热身设备中的任何一种后，BV 没有统计学上的显著差异（510.3-2721.5g 或 18-96oz），与之前的棒球研究相似。这表明，男女大学运动员的结果相似，大学垒球运动员可以在预备区使用 8 种热身设备中的任何一种，并且具有相似的 BV。然而，与之前的其他棒球研究相似，不建议女性大学垒球运动员在预备区使用流行的商业甜甜圈环进行热身，因为它产生的 BV 最慢。
