The phenomenon of walking feeling harder as we age is not just a figment of our imagination. It's a biological phenomenon, a shift in our nervous system's command over our muscles, particularly around the ankles. This shift is a survival mechanism, prioritizing stability over speed to prevent falls. But it comes at a cost: it drains our energy and slows us down.
A recent study published in the journal Gait & Posture, titled 'Ageing alters ankle mechanics and muscle co-contraction patterns across the gait cycle', sheds light on this intriguing phenomenon. Conducted by researchers at Flinders University and the University of Canberra, the study reveals that our bodies adopt a 'safety-first' mindset as we age, prioritizing fall prevention over smooth, effortless movement. While this keeps us upright, it drains our energy and slows us down.
The study, which analyzed 107 healthy individuals aged 26 to 86, found that the nervous system actively chooses stability over peak performance. This 'safety-first' pivot fundamentally alters our natural stride, sacrificing speed and fluid movement to drastically lower our chances of wiping out. It's a smart defensive strategy, but it explains why older adults often feel exhausted after a walk and struggle with longer distances.
The real-world risk of falling is a serious concern. This shift in ankle mechanics also explains why it becomes much harder for older adults to quickly catch their balance after a sudden slip or trip. The study's findings highlight the importance of targeted movement and the need for older adults to incorporate balance drills, coordination practice, and exercises that mimic the natural, synchronised ways our muscles fire with every single step.
Staying active is one of the most important things people can do, and small, consistent exercises can help you stay confident, mobile, and independent for longer. Standard strength training isn't enough; fitness routines for older adults need to actively incorporate balance drills, coordination practice, and exercises that mimic the natural, synchronised ways our muscles fire with every single step.
Walking is a 'powerful and free' way to improve your health. Just around 30 minutes a day can reduce heart disease risk by 19 per cent, boost mood, build muscle, and sharpen your mind. Walking also repairs the body, improves circulation, and oxygenates the muscles. It's a low-impact exercise that's gentle on the joints, and every movement helps the blood circulation of the body. It flushes down the lactic acid that can tend to build up in the joints and cause a lot of soreness. The more you walk, the stronger your muscle memory becomes, and fat begins to burn more efficiently.
Walking is especially important for women in the perimenopause or menopausal stage, as it helps to regulate hormones and stimulate the bones to move and grow stronger. It's a natural, effective way to maintain mobility and independence as we age, and it's a powerful tool for preventing falls and maintaining a healthy, active lifestyle.
