Relationship between Isokinetic Average Force, Average Torque, Peak Force, and Peak Torque of the Knee Extensor and Flexor Musculature
The purpose of this study was to determine the relationship between average force, average torque, peak force, and peak torque produced by the knee musculature. Twenty women were assessed for isokinetic concentric and eccentric knee extensor and flexor muscular strength at a velocity of 90 deg/sec. Correlational analyses showed relationships ranging from r = 0.89 to r = 0.94 for concentric exte...
متن کاملIsokinetic dynamometry. Applications and limitations.
Isokinetic contraction is the muscular contraction that accompanies constant velocity limb movements around a joint. The velocity of movement is maintained constant by a special dynamometer. The resistance of the dynamometer is equal to the muscular forces applied throughout the range of movement. This method allows the measurement of the muscular forces in dynamic conditions and provides optim...
متن کاملImportance of correcting isokinetic peak torque for the effect of gravity when calculating knee flexor to extensor muscle ratios.
The purpose of our investigation was to compare, for the hamstring and quadriceps femoris muscles, peak torque values uncorrected for gravity with the peak torque values corrected for gravity and to determine the effect of making this correction on the hamstring to quadriceps femoris muscle peak torque ratio at slow and fast isokinetic speeds. We measured peak torques isokinetically at 60 degre...
متن کاملCriterion-related validity of knee joint-position-sense measurement using image capture and isokinetic dynamometry.
CONTEXT Clinicians require portable, valid, and cost-effective methods to monitor knee joint-position-sense (JPS) ability. OBJECTIVE To examine the criterion-related validity of image-capture JPS measures against an isokinetic-dynamometer (IKD) procedure. DESIGN Random crossover design providing a comparison of knee JPS measures from image capture and IKD procedures. PARTICIPANTS 10 healt...
متن کاملIsokinetic dynamometry of the knee extensors and flexors in
Background :This paper explores the gender-related bilateral differences of extensor and flexor torques of the knee joint at low and high angular velocities in Iranian healthy males and females. Methods : 70 healthy subjects (29 males (26.61±4.34 yrs and 41 females with average age of 23.07±3.70 yrs)) were participated in this study. Isokinetic peak torque values for knee extensors and flex...
