Human Muscular System in Running - Anatomy & Biomechanics #3432113 (License: Personal Use)

The image displays a full-body anatomical rendering of a male figure mid-stride, with superficial and deep musculature exposed to illustrate biomechanical function during running. Key muscle groups-including the gluteus maximus, quadriceps, hamstrings, gastrocnemius, and core stabilizers-are rendered in realistic tone and fiber orientation. The pose emphasizes dynamic contraction, joint articulation, and neuromuscular coordination essential for forward propulsion and balance.
