Muscles of the Knee FLEXORS:Hamstrings (semi membranosus, semiteninosus, biceps femoris), gastrocnemius, popliteus EXTENSORS:vastus medialis, vastus lateralis, vastus intermedius, rectus femoris COMMENTS:The main movements of the knee are flexion and extension. For lateral knee pain, look at the ...
The purpose of this study was to compare the EMG activity of Vastus Medialis Oblique (VMO) and Vastus Lateralis (VL) muscles in the singlejoint knee extension (KE) and the multijoint leg press (LP). Subjects performed two maximal voluntary isometric contractions (MVC) and LP and KE actions...

Ten healthy female subjects performed 1 min static knee extension exercise at low (30%) and high (60%) fraction of maximal voluntary contraction (MVC). Muscle oxygenation in the vastus lateralis (VL) was monitored using multi channel near-infrared spectroscopy. Half time reoxygenation (T(1/2)...
The thigh muscles are located between your knee and the bottom of your spinal cord. This is usually referred to as the “upper leg” and is divided into three parts: Anterior thigh Medial thigh Posterior thigh The anterior thigh muscles are the ones that are in the front of your body, in...
The biceps flex to lift the forearm while the triceps extend it. The quadriceps are major muscles on the anterior thigh to extend the lower leg to kick, while the hamstrings on the posterior thigh flex the knee to squat. Create an account to start this course today ...
For example, to extend the knee, a group of four muscles called the quadriceps femoris in the anterior compartment of the thigh are activated (and would be called the agonists of knee extension). However, to flex the knee joint, an opposite or antagonistic set of muscles called the hamstring...
摘要: Highlights Active unilateral knee extension in sitting (AKEiSit) was compared between two interventions. Jack-knife stretching (JKS) or active knee extension stretching (AKES) was conducted. There was no difference in the AKEiSit changes between the two interventions....
Dynamic knee valgus (DKV) is a risk factor for non-contact anterior cruciate ligament (ACL) injuries. Understanding the changes in the electromyographic activity of the lower extremity muscles in individuals with DKV helps trainers design ACL injury prev
In the backwards condition, the upper-body rotation was not achieved through hip extension (remained in initial posture), but by knee bending such that upper body and thigh segments pivoted together around the knee joint (see Supplementary Fig. S2). Influence of AMP weight, noise, and ...
