Abstract

Abstract: Suzuki, K, Mizoguchi, Y, Kimura, F, Fujisaki, K, Yokoyama, D, Hall, T, and Akasaka, K. Correlation between muscle strength, swing speed, batting statistics, and body composition parameters in high school baseball players: a retrospective observational study. J Strength Cond Res XX(X): 000-000, 2024-Body composition has emerged as a pivotal factor influencing baseball player performance. The purpose of this study was to examine the relationships between muscle strength, swing speed, batting statistics, and body composition in high school baseball players. This retrospective study evaluated 29 high school baseball players included critical parameters related to body composition (body fat percentage, lean body mass [LBM], fat mass index [FMI], and fat-free mass index [FFMI]), muscle strength (bench press, squat, deadlift), batting statistics (batting average, on-base percentage, slugging percentage, on-base plus slugging), and swing speed. These metrics were gathered using a body composition analyzer (Omron HBF-701; Omron Healthcare Co., Kyoto, Japan). After the correlation analysis with body composition, a subsequent multivariate analysis was conducted. Multivariate regression analysis identified LBM (p < 0.05, p < 0.01) as a significant predictor for bench press and swing speed, FFMI for squat (p < 0.01), and FMI for deadlift (p < 0.05). No significant association was found between body composition and batting statistics. Lean body mass has been identified as an important contributing factor to swing speed, suggesting the need for body composition management among high school baseball players and coaches to enhance performance and functionality. However, no association was found between batting statistics and body composition. Therefore, it is suggested that high school baseball players prioritize the development of technical skills over swing speed and muscle strength to improve batting statistics.

高中棒球运动员的肌肉力量、挥棒速度、击球数据和身体成分参数之间的相关性:回顾性观察研究
摘要:Suzuki,K,Mizoguchi,Y,Kimura,F,Fujisaki,K,Yokoyama,D,Hall,T,and Akasaka,K. 高中棒球运动员肌肉力量、挥棒速度、击球统计和身体成分参数之间的相关性:一项回顾性观察研究。J Strength Cond Res XX(X):000-000,2024-身体成分已成为影响棒球运动员表现的关键因素。本研究旨在考察高中棒球运动员的肌肉力量、挥棒速度、击球数据和身体成分之间的关系。这项回顾性研究对 29 名高中棒球运动员进行了评估,包括与身体成分(体脂百分比、瘦体重[LBM]、脂肪质量指数[FMI]和无脂肪质量指数[FFMI])、肌肉力量(卧推、深蹲、举重)、击球数据(平均打击率、上垒率、击球率、上垒率加击球率)和挥棒速度有关的关键参数。这些指标是使用身体成分分析仪(Omron HBF-701; Omron Healthcare Co.)在对身体成分进行相关分析后,又进行了多变量分析。多变量回归分析发现,LBM(p < 0.05,p < 0.01)是卧推和摆动速度、深蹲FFMI(p < 0.01)和举重FMI(p < 0.05)的重要预测因子。在身体成分和击球数据之间没有发现明显的关联。瘦体重被认为是影响挥棒速度的一个重要因素,这表明高中棒球运动员和教练需要对身体成分进行管理,以提高成绩和功能。然而,研究并未发现击球数据与身体成分之间存在关联。因此,建议高中棒球运动员优先发展技术技能,而不是挥棒速度和肌肉力量,以提高打击统计数据。

期刊介绍: The editorial mission of The Journal of Strength and Conditioning Research (JSCR) is to advance the knowledge about strength and conditioning through research. A unique aspect of this journal is that it includes recommendations for the practical use of research findings. While the journal name identifies strength and conditioning as separate entities, strength is considered a part of conditioning. This journal wishes to promote the publication of peer-reviewed manuscripts which add to our understanding of conditioning and sport through applied exercise science.
