Human Muscular System in Motion - Running Anatomy Diagram #3073483 (License: Personal Use)

This high-detail medical illustration shows a male figure in dynamic running motion, with all major muscle groups-including deltoids, pectorals, rectus abdominis, quadriceps, hamstrings, and calf muscles-clearly delineated in vibrant red against a white background. The underlying skeletal framework is partially visible at joints and extremities, emphasizing biomechanical relationships during locomotion. Fine line work captures fascial layers and muscle fiber directionality for clinical and educational precision.

Used in medical textbooks, physiology courses, physical therapy resources, and fitness training guides to explain functional anatomy during gait; targets users seeking visual learning aids for kinesiology or exercise science.
