Abstract：
BACKGROUND The purpose of this study was to determine how the combination of plyometric training (PT), which builds strength through fast, repetitive extensions and contractions, and kettlebell training (KT), using a device that is smaller than a barbell and allows for strength and full-body work, affects the physical performance and performance of high school pitchers during the season. MATERIAL AND METHODS Participants (n=30 males; age group=16-19 years) were randomized into 3 groups: compound training group (CTG) (n=10), plyometric training group (PTG) (n=10), and kettlebell group (KTG) (n=10). All groups performed training twice weekly for 4 weeks. Pre- and post-intervention assessments were conducted on isokinetic strength to measure strength, vertical jump (VJ) to measure power, dynamic balance (Y-balance), and ball speed (BS) to measure baseball performance. RESULTS We found there was increased strength, VJ, Y-balance, and BS in the CTG, PTG, and KTG (p=.000). CTG had significantly different results than PTG and KTG (p=.000). There was a significant difference in increased strength of the right knee joint flexors between PTG and KTG (p=.000). CONCLUSIONS CTG, PTG, and KTG for pitchers during the season improved significantly. These results suggest that combination training, rather than just 1 type of training, affects pitchers\' strength, VJ, Y-balance, and BS during the season.
摘要：
背景这项研究的目的是确定如何结合屈光度训练(PT)，通过快速建立力量，重复的伸展和收缩，和壶铃训练(KT)，使用比杠铃小的装置，允许力量和全身工作，影响高中投手在赛季中的身体表现和表现。材料和方法参与者（n=30男性；年龄组=16-19岁）被随机分为3组：复合训练组（CTG）（n=10），补强训练组(PTG)(n=10)，和酮钟组（KTG）（n=10）。所有组每周进行两次训练，共4周。对等速强度进行干预前和干预后评估，以测量强度，垂直跳变(VJ)来测量功率，动平衡(Y-balance),和球速（BS）来衡量棒球表现。结果我们发现力量增加了，VJ,Y形平衡,和BS在CTG中，PTG,和KTG(p=.000)。CTG的结果与PTG和KTG的结果显着不同（p=.000）。PTG和KTG之间的右膝关节屈肌强度增加存在显着差异（p=.000）。结论CTG,PTG,而KTG对于投手在赛季中的提升明显。这些结果表明，组合训练，而不仅仅是一种类型的训练，影响投手的力量，VJ,Y形平衡,和BS在季节。
