Improving and maintaining an ideal body composition is important for sporting achievement and good health. Body composition assessment is therefore a tool used to monitor training and to evaluate the objectives of a training plan for health purposes. Ultrasound (US) emerges as an alternative to evaluate the thickness of subcutaneous cellular tissue, as well as muscle thickness: (1) Background: We aim to evaluate and compare the anthropometric and ultrasound measurements used to quantify the effects of strength training. (2) Methods: A total of 31 students (22.3 ± 4.14 years of age), 25 men and 6 women, from the Professional Programme in Sport were enrolled in the Physical Preparation course at the Institución Universitaria Politécnico Colombiano Jaime Isaza Cadavid. Protocol: Pre- and post-intervention ultrasound and anthropometric evaluations of a strength training programme with a predominance of the eccentric component were performed three times a week for 4 weeks. For the pre- and post-intervention relationship of the quantitative anthropometric and ultrasound variables, the Wilcoxon signed-rank test was used; the effect size of a Wilcoxon test was also calculated using the rank correlation, and the correlation of the anthropometric and ultrasound variables was determined using Spearman's correlation coefficient, with a -value < 0.05 considered statistically significant. (3) Results: There were no statistically significant differences in the anthropometric variables assessed, but there were significant differences in measures of quadricep muscle size and in the control parameter echo-intensity (EI) of subcutaneous fat in the variables. (4) Conclusions: The US of the quadriceps can measure changes in muscle thickness even without changes in muscle mass assessed by anthropometry, making it an excellent tool for the evaluation and monitoring of strength training.
改善并维持理想的身体成分对于运动成绩和健康状况至关重要。因此，身体成分评估是一种用于监测训练以及评估出于健康目的的训练计划目标的工具。超声（US）成为评估皮下细胞组织厚度以及肌肉厚度的一种替代方法：（1）背景：我们旨在评估和比较用于量化力量训练效果的人体测量学和超声测量方法。（2）方法：来自哥伦比亚国立理工大学海梅·伊萨扎·卡达维德体育专业课程的31名学生（年龄22.3±4.14岁），其中25名男性和6名女性，参加了体能准备课程。方案：对一项以离心成分为主的力量训练计划进行干预前和干预后的超声及人体测量学评估，每周进行三次，共4周。对于定量人体测量学和超声变量的干预前和干预后关系，使用Wilcoxon符号秩检验；还使用秩相关计算Wilcoxon检验的效应大小，并使用Spearman相关系数确定人体测量学和超声变量的相关性，P值<0.05被认为具有统计学意义。（3）结果：所评估的人体测量学变量没有统计学上的显著差异，但股四头肌大小的测量以及变量中皮下脂肪的对照参数回声强度（EI）存在显著差异。（4）结论：股四头肌的超声检查即使在通过人体测量学评估的肌肉质量没有变化的情况下，也能够测量肌肉厚度的变化，使其成为评估和监测力量训练的优秀工具。
