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...

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 ...
How To Stretch The Knee Muscles Tightness in the muscles around the knee changes how the knee moves and how the forces go through the joint which can lead to a whole host of knee problems. Tightness in the muscles behind knee can limit knee extension and tightness in the muscles above knee...
produce the opposite motion --- extension of the thigh at the hip and flexion of the leg at the knee. Lateral muscles, such as the gluteus medius, abduct the thigh at the hip while the medial groin muscles adduct the thigh. All of these muscle groups provide powerful contractions to prope...
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 muscles groups around the knee have an antigravity role and offer knee stabilization during standing position and stability in a variety of different positions. They can be classified based on their anatomic location as well as on their function. The muscles of the thigh and lower leg are ...
To investigate the effects of increasing load on changes in the muscle activity ratio and onset of vastus medialis (VM), vastus lateralis (VL) and biceps femoris (BF) during load-carrying walking.Sixteen strength-trained men performed an isometric test for knee flexion/extension using a dynamomet...

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....
