A 10-year study published in the British Journal of Sports Medicine found that the inability to balance on one leg for 10 seconds in middle-to-older age was linked to an 84% higher risk of all-cause mortality. Single-leg balance requires precise real-time communication between proprioceptors in the feet, the vestibular system, and the cerebellum. Maintaining balance preserves motor unit recruitment, neural firing rates, and prevents falls.
