Explained
This assertion is based on a study that compared the effects of leg press and leg extension exercises on muscle growth. The study found that the rectus femoris, one of the quadriceps muscles, grew more significantly with leg extension exercises. This is because the rectus femoris is a biarticular muscle that crosses both the hip and knee joints, and leg extension exercises allow for a more focused contraction of this muscle.
Context for Assertion
Muscle hypertrophy is the increase in size of muscle fibers, and it's essential to understand how different exercises affect different muscle groups to optimize training.
Concepts for Assertion
Biarticular muscle
A muscle that crosses two joints, such as the rectus femoris.
