Muscle Shape: The Hidden Factor in Performance

The video explores the architecture of skeletal muscles, focusing on the structure of muscle fibers, connective tissues, and tendons. It explains how these components contribute to muscle movement and the different fiber orientations, such as circular, parallel, and oblique. The video also discusses the functional significance of muscle shapes, emphasizing the balance between force and range of motion.
