A recent study conducted by researchers from Flinders University and the University of Canberra has uncovered the reasons behind slower and more tiring walking in older adults. The research indicates that as individuals age, their bodies adopt a 'safety-first' walking style that prioritizes stability over speed and energy efficiency. Analyzing movement data from 107 healthy adults aged 26 to 86, the study found that older adults increasingly engage opposing muscles around the ankle simultaneously, a phenomenon known as co-contraction. This stiffening of the joint enhances balance but requires more effort, resulting in reduced push-off power and shorter strides. The lead author, Dr. Cody Lindsay, highlights that these changes, while improving safety, contribute to increased fatigue and a greater risk of falls. The findings suggest that exercise programs for older adults should not only focus on strength but also emphasize balance and coordination. Simple activities like tai chi and lower-leg strengthening exercises can help maintain mobility and independence. The researchers aim to use these findings to develop better prevention and rehabilitation strategies for healthy aging.
