Background: Many injury prevention and rehabilitation programs aim to train hamstring and quadriceps co-activation to constrain excessive anterior tibial translation and protect the anterior ...

The key muscles include: Left hemi-diaphragm Iliopsoas Tensor fascia latae Vastus lateralis Bicep femoris These left-sided muscles are typically more active and in a suboptimal position compared to ...

(ii) Simulation: The process of squatting was simulated in the AnyBody.7.1 software, the result showed that muscle activity of the gluteus maximus, rectus femoris, vastus medialis, vastus lateralis, ...

Muscle electromyography (EMG) signals were used to validate model-simulated muscle activations (Supplementary Material 1), which included the rectus femoris (RF), vastus lateralis (VL), vastus ...

Background: The m. quadriceps femoris is the strongest muscle in the human body and plays an important role in sports, activities of daily living and independence. Two older studies showed ...
