The purpose of the study was to analyze changes in physique, body composition, physical fitness, and isokinetic strength in female collegiate taekwondo athletes. The study included 14 subjects, of whom 8 were followed up throughout the study. Anthropometric characteristics included body weight, height, sitting height, circumferences, and bone width. Physical fitness parameters included flexibility, agility, muscle strength, muscular endurance, power, speed, and cardiorespiratory endurance. Peak torque, mean power, and H/Q ratio were analyzed by using Cybex 770. All data were analyzed by using the SAS statistical program. Paired t test was performed, with 0.05 as the significance level. The results indicated significant changes in body weight, and upper arm and flexed upper arm circumferences during the experimental period. Test scores for plate tapping, and sit and reach significantly increased, but that for power decreased. In addition, the peak power of right flexion at 180°/sec was significantly increased, as well as the mean power of right and left flexion, and the H/Q ratio at 180°/sec.
本研究的目的是分析女子大学跆拳道运动员的体格、身体成分、身体素质和等速肌力的变化。该研究包括14名受试者，其中8名在整个研究过程中接受了随访。人体测量特征包括体重、身高、坐高、周长和骨宽。身体素质参数包括柔韧性、敏捷性、肌肉力量、肌肉耐力、力量、速度和心肺耐力。使用Cybex 770分析峰值扭矩、平均功率和H/Q比值。所有数据均使用SAS统计程序进行分析。进行配对t检验，以0.05作为显著性水平。结果表明，在实验期间体重、上臂和屈臂周长有显著变化。拍板测试和坐立前屈测试的分数显著提高，但力量测试分数下降。此外，180°/秒时右屈的峰值功率显著增加，以及左右屈的平均功率和180°/秒时的H/Q比值也显著增加。
