Variation in muscle strength decrements and biomechanical plasticity in older adults during level and incline walking

Old vs young adults had lower ankle plantarflexor but not hip extensor strength. They also showed biomechanical plasticity (BP) through higher hip/ankle ratios of peak joint torques & powers in level & inclined walking. BP ratios were not correlated however with the relative strengths of hip vs ankle muscle groups in either gait.
