Biomechanics of Running - Visual Guide to Leg Mechanics and Muscle Activation #3819095 (License: Personal Use)

This conceptual illustration depicts a runner in mid-stride, with transparent lower limbs exposing mechanical analogs of hip, knee, and ankle joints represented as interlocking gears. Muscle groups are highlighted in green (agonists), orange (antagonists), and gray (stabilizers), illustrating dynamic force distribution during locomotion. The design merges anatomy with engineering metaphors to clarify complex biomechanical principles.

Used on fitness, sports science, physical therapy, or kinesiology websites to explain gait analysis, injury prevention, or training optimization; targets users seeking visual learning about human movement efficiency.
