WHY WALKING GETS HARDER AS WE AGE Getting older usually means slowing down, but have you ever wondered why a simple walk can suddenly feel so much harder? A new study from Flinders University and the University of Canberra explains what’s happening in our bodies, revealing that as we age, we unconsciously trade walking efficiency for stability. This move keeps us safer but comes with its own costs ( Flinders University, 2026 ). The research team, led by Dr. Cody Lindsay, looked at the walking patterns of 107 healthy adults aged 26 to 86. Their findings suggest that older adults start to stiffen their ankles more with each step, a strategy called “co-contraction,” where opposing muscles around the ankle fire at the same time. This makes the joint stiffer and steadier, which can help prevent falls—a real concern as we age ( Lindsay et al., 2026 ). But there’s a downside. Dr. Lindsay explained, “Stiffening the joint makes walking safer, but it also means the muscles are working hard...
