Reproducibility of computer measurement of maximal isometric strength and electromyography in sedentary middle-aged women

摘要: The objectives of this study were (i) to determine the reproducibility computer measurements isometric strength and related electromyography in several muscle groups sedentary middle-aged women, (ii) evaluate effects different digital signal averaging methods on reproducibility, (iii) final test score be preferred terms improved measurements, (iv) potential advantages provided by measurement. Fifteen subjects measured three times within a 2-week period. consisted recordings maximal rate force production during trunk extension flexion, leg dominant forearm flexion with simultaneous surface electromyography, except flexors. following four scores determined for each trial: maximum scores, mean two highest median scores. measurement generally more reproducible (coefficient variation, CV, approximately 6% intraclass correlation coefficient ICCC, 0.90) than those other (CV > 10%, ICCC 0.13–0.97). There was no obvious preference any type or width window analysis. For comparable that voltmeter assessments. Computer analysis seems versatile method determining parameters neuromuscular performance reasonable reproducibility.
