Effects of motorized vs non-motorized treadmill training on hamstring/quadriceps strength ratios
Concentric eccentric conventional
2015/5/8
Previous literature suggests that muscular involvement and
biomechanical changes elicit different responses between overground and treadmill training.
The effect of mild symptomatic patellar tendinopathy on the quadriceps contractions and the Fente motion in elite fencers
Patellar tendinopathy elite fencers isokinetic kinematics
2015/5/8
To investigate how mild symptomatic patellar tendinopathy (PT) affects quadriceps contractions and the Fente motion, this case-control study examined elite fencers who continue to train and play fully...
Changes in Quadriceps Muscle Activity During Sustained Recreational Alpine Skiing
Muscle coordination recruitment electromyography wavelet analysis
2015/5/6
During a day of skiing thousands of repeated contractions take place. Previous research on prolonged recreational alpine skiing show that physiological changes occur and hence some level of fatigue is...
Inhomogeneous Quadriceps Femoris Hypertrophy in Response to Strength and Power Training
REGION-SPECIFIC HYPERTROPHY CROSS-SECTIONAL AREA MUSCLE VOLUME JUMP SQUAT BACK SQUAT
2017/4/20
Introduction: Previous studies have reported inhomogeneous changes in quadriceps femoris (QF) cross-sectional area (CSA) in response to strength training. It is assumed that these differential changes...
Rapid Hamstrings/Quadriceps Strength in ACL-Reconstructed Elite Alpine Ski Racers
RATE OF FORCE DEVELOPMENT SEX DIFFERENCES LIMB ASYMMETRY KNEE STABILITY
2017/4/14
Purpose: Because of the importance of hamstrings (HAM) and quadriceps (QUAD) strength for anterior cruciate ligament (ACL) injury prevention and the high incidence of ACL injury in ski racing, HAM and...
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...
Rapid Hamstrings/Quadriceps Strength Capacity in Professional Soccer Players with Different Conventional Isokinetic Muscle Strength Ratios
Muscular torque isometric action injury
2015/5/12
Muscle strength imbalance can be an important factor in hamstrings muscle strain. A hamstrings/quadriceps (H/Q) strength ratio based on concentric peak torque values (Hcon:Qcon) has traditionally been...
Quadriceps Activation Following Knee Injuries: A Systematic Review
arthrogenic muscle inhibition voluntary activation twitch interpolation superimposed burst central activation ratio
2010/9/8
Arthrogenic muscle inhibition is an important underlying factor in persistent quadriceps muscle weakness after knee injury or surgery.To determine the magnitude and prevalence of volitional quadriceps...
Surgical Reconstruction of the Anterior Cruciate Ligament：The Central Quadriceps Tendon as an Alternative Graft Source
Anterior Cruciate Ligament Central Quadriceps Tendon
2009/9/1
Significant advances in surgical reconstruction of the anterior
cruciate ligament (ACL) have been made since Jones' described
open reconstruction with the central one-third patellar tendon
in 1963....
Association of Quadriceps and Hamstrings Cocontraction Patterns With Knee Joint Loading
neuromuscular system biomechanics landings anterior cruciate ligament coactivation
2010/9/9
Sex differences in neuromuscular control of the lower extremity have been identified as a potential cause for the greater incidence of anterior cruciate ligament (ACL) injuries in female athletes comp...
Sagittal-Plane Trunk Position, Landing Forces, and Quadriceps Electromyographic Activity
anterior cruciate ligament ground reaction forces injury prevention risk factors
2010/9/9
Researchers have suggested that large landing forces, excessive quadriceps activity, and an erect posture during landing are risk factors for anterior cruciate ligament (ACL) injury. The influence of ...
