Abstract

The purpose of this study was to examine the differences in specific physical fitness of the national amateur women's boxer. The Korean women's national amateur boxers were classified into the lightweight category (LWC, n=21) and middleweight category (MWC, n=13), and body composition (percentage body fat and body mass index) and specific physical fitness (maximal muscle strength, anaerobic power, isokinetic muscle strength, cardiopulmonary endurance) were measured. The Mann-Whitney U-test was conducted to determine the differences in the body composition and specific physical fitness in women's boxers. The percentage body fat (P=0.004) and body mass index (P<0.001) were significantly higher in the LWC compared to MWC. In addition, LWC showed significantly higher isokinetic muscle strength (P<0.001), upper anaerobic mean power (P=0.002), maximal muscle strength (P=0.003), and maximal heart rate at anaerobic threshold (P=0.029), maximal oxygen consumption (P<0.001) and the 20-m shuttle-run exercise (P=0.004) compared to MWC. In conclusion, the body fat percentage and body mass index levels among body composition were significantly higher in the MWC than in the LWC, and the constant muscle strength, maximum muscle strength, and cardiopulmonary endurance levels were significantly higher in the LWC than in the MWC. The results of this study are expected to provide useful data for planning future strategies for efficient and scientific training programs for each weight category.

按体重类别对韩国国家女子业余拳击运动员的体能状况进行比较分析。

本研究的目的是考察全国业余女子拳击手在专项体能方面的差异。将韩国全国业余女子拳击运动员分为轻量级（LWC，21 人）和中量级（MWC，13 人），并测量了身体成分（体脂百分比和体重指数）和专项体能（最大肌力、无氧力量、等动肌力、心肺耐力）。采用曼-惠特尼 U 检验来确定女子拳击运动员在身体成分和专项体能方面的差异。与 MWC 相比，体脂百分比（P=0.004）和体重指数（PPP=0.002）、最大肌力（P=0.003）和无氧阈值最大心率（P=0.029）、最大耗氧量（PP=0.004）。总之，身体成分中的体脂率和体重指数水平，MWC 显著高于 LWC；恒定肌力、最大肌力和心肺耐力水平，LWC 显著高于 MWC。本研究的结果有望为今后针对不同体重类别制定高效、科学的训练计划策略提供有用的数据。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
