The Influence of Velocity Overshoot Movement Artifact on Isokinetic Knee Extension Tests
biomechanics dynamometry constant velocity phases of movement
2015/5/4
Exercise on an isokinetic device involves three distinct movement phases: acceleration, constant velocity, and deceleration. Inherent in these phases are unique occurrences that may confound test data...
Effect of Blood Flow Restriction on Tissue Oxygenation during Knee Extension
RESISTANCE TRAINING EXERCISE BLOOD FLOW RESTRICTION FATIGUE DIFFUSE OPTICS TISSUE OXYGENATION
2017/4/14
Purpose: Time-resolved near-infrared spectroscopy was used to quantify tissue oxy- and deoxyhemoglobin concentrations ([HbO2] and [HbR]) and O2 saturation (stO2) in the oblique fibers of the vastus me...
The Influence of Body Position on Load Range During Isokinetic Knee Extension/Flexion
Rate of velocity development acceleration deceleration
2015/3/23
Isokinetic range of motion (ROM) has three distinct phases: rate of velocity development (RVD), load range (LR), and deceleration (DCC). The purpose of this study was to determine if differences in is...
CONTRIBUTION OF HAMSTRING FATIGUE TO QUADRICEPS INHIBITION FOLLOWING LUMBAR EXTENSION EXERCISE
Superimposed burst technique electromyography spectral median frequency
2015/3/18
The purpose of this study was to determine the contribution of hamstrings and quadriceps fatigue to
quadriceps inhibition following lumbar extension exercise. Regression models were calculated consi...
The Effects of Knee Joint Pain and Disorders on Knee Extension Strength and Walking Ability in the Female Elderly
Knee Joint Pain Knee Joint Disorder Knee Extension Strength Gait Female Elderly
2013/1/31
This study examines the differences in leg strength and walking ability among groups with different knee problems. The participants were 328 elderly females (60 - 94 years old; mean age 76.1 years; SD...
Muscle Activation and Movement Patterns During Prone Hip Extension Exercise in Women
electromyography motor control verbal cues
2010/9/9
The consistency of muscle activation order during prone hip extension has been debated.
Bilateral Medial Tibiofemoral Joint Stiffness in Full Extension and 20° of Knee Flexion
arthrometry leg dominance valgus stress
2010/9/9
The valgus stress test is used clinically to assess injury to the medial knee structures in 2 positions: full extension and some degree of flexion. The amount of flexion used to “isolate” the medial c...
Allometrically adjusted isokinetic leg extension torque of adults in relation to body mass
Allometric scaling Leg extension torque
2010/9/17
The purpose of the study was to examine the isokinetic leg extension torque of adult participants using allometric scaling to account for differences in body mass. 10 men (23.1y, 1.72m & 64.5kg) and n...
