Abstract

Background and aims: Muscle strength (MS) has been associated with better cardiometabolic health prognosis. However, the result for the beneficial relationship seems to be dependent on the influence of body size in determining MS levels. We investigate the association between allometric MS indexes and its association with cardiometabolic risk factors in adolescents. Methods: It was a cross-sectional study comprising 351 adolescents (male: 44.4%; age range 14-19 years) from Southern Brazil. MS was assessed by handgrip strength and three different allometric approaches were adopted: 1) MS index based on theoretical allometric exponent; 2) MS index including body mass and height; 3) MS index including fat-free mass and height. Obesity, high blood pressure, dyslipidemia, glucose imbalance and high-sensitivity C-reactive protein were investigated as individual factors or as combinations (either as combinations of components - presence of two adverse conditions, or number of components present in an individual - 0, 1, 2, 3+ cardiometabolic risk factors). Logistic and multinomial logistic regression analyses adjusted for confounding factors were used. The statistical significance adopted was 5%. Results: MS index based on theoretical allometric exponent was associated with lower likelihood (OR: 0.54; 95% CI: 0.28 - 0.89) for the presence of three or more cardiometabolic risk factors in the same individual. Conclusion: This study suggests that MS index based on the theoretical allometric exponent can be superior to allometric MS indexes that included body mass and height, or fat-free mass and height in representing the presence of high number of cardiometabolic risk factors in adolescents.

青少年肌肉力量指数及其与心脏代谢风险因素的关系:异速法
背景和目的:肌肉力量(MS)与更好的心脏代谢健康预后有关。然而,这种有益关系的结果似乎取决于体型对决定 MS 水平的影响。我们研究了青少年肌肉力量指数与心血管代谢风险因素之间的关系。研究方法这是一项横断面研究,包括来自巴西南部的 351 名青少年(男性:44.4%;年龄在 14-19 岁之间)。MS通过手握力进行评估,并采用了三种不同的计量方法:1) MS 指数基于理论计量指数;2) MS 指数包括体重和身高;3) MS 指数包括去脂体重和身高。肥胖、高血压、血脂异常、血糖失衡和高敏 C 反应蛋白作为单个因素或组合因素进行调查(或作为成分组合--存在两个不利条件,或作为个体中存在的成分数量--0、1、2、3 个以上的心脏代谢风险因素)。对混杂因素进行调整后,采用逻辑和多项式逻辑回归分析。统计显著性为 5%。结果基于理论异速指数的 MS 指数与同一人存在三个或三个以上心脏代谢风险因素的较低可能性相关(OR:0.54;95% CI:0.28 - 0.89)。结论本研究表明,在代表青少年存在大量心脏代谢风险因素方面,基于理论异速指数的 MS 指数优于包括体重和身高或去脂体重和身高的异速 MS 指数。

期刊介绍: Research Quarterly for Exercise and Sport publishes research in the art and science of human movement that contributes significantly to the knowledge base of the field as new information, reviews, substantiation or contradiction of previous findings, development of theory, or as application of new or improved techniques. The goals of RQES are to provide a scholarly outlet for knowledge that: (a) contributes to the study of human movement, particularly its cross-disciplinary and interdisciplinary nature; (b) impacts theory and practice regarding human movement; (c) stimulates research about human movement; and (d) provides theoretical reviews and tutorials related to the study of human movement. The editorial board, associate editors, and external reviewers assist the editor-in-chief. Qualified reviewers in the appropriate subdisciplines review manuscripts deemed suitable. Authors are usually advised of the decision on their papers within 75–90 days.
