Reliability of the BTE Dynatrac isotonic dynamometer

摘要: The BTE Dynatrac is an isotonic dynamometer in where the preset resistance determines effort and limb must overcome to accelerate through ROM. Previous reliability studies of isokinetic devices do not apply this type dynamometer. Therefore, purpose study was assess Isotonic Dynamometer using average work power determine whether can produce consistent results under different loads between exercise sessions. Twenty-nine (M = 19; F 10) recreationally active college students underwent identical testing on three occasions. On a day before testing, peak torque measured from 6 s maximal voluntary isometric contraction (MVIC) at 70° knee flexion. This value determined used for During sessions each subject performed six repetitions extensions (20%, 40%, 60% MVIC) 90° order nonconsecutive days by balanced Latin Square. Average were recorded analyzed. measurement excellent regardless load (20% MVIC 0.82; 40% 0.83; 0.90). MVIC(0.86) MVIC(0.80), but only fair 20% MVIC(0.57). We conclude that clinicians be confident comparing measurements moderate higher loads.
