As the saying goes, “Life lies in movement.” Walking is an innate human ability. As the most basic form of human activity, it is also an aerobic exercise and widely recognized by the medical community as one of the best exercises.
Recently, a new study suggests that people who struggle to walk even a kilometer have a higher risk of fractures.
A study has sparked widespread attention.
On January 23, the Journal of the American Medical Association Network Open published a study conducted by the Sydney Garvan Institute of Medical Research, which found that people who cannot walk a kilometer have a higher risk of fractures.
The study included data from 267,000 adults aged 45 and older. By asking, “Does your health limit you from walking a kilometer?” with responses ranging from “not at all,” “somewhat,” and “very much,” the study investigated their walking ability and assessed their fracture risk. A Cox proportional hazards model was used to analyze the relationship between walking impairment and the five-year risk of fracture.
Over an average follow-up of 4.1 years, fracture risk increased significantly with increasing severity of walking impairment. Compared to those who could walk a kilometer without difficulty, those who reported having “significant limitations” had a significantly increased risk of fractures, with women in particular experiencing a 60% higher risk.
This study not only reveals the close link between walking ability and fracture risk but also emphasizes the importance of monitoring personal bone health. It reminds us that a decrease in walking distance or walking ability may be a sign of bone health problems, making the ability to walk a key indicator of bone health.
Understanding how walking can “uncover” health problems
Walking may seem like a simple, everyday form of exercise, but it’s actually a complex process involving the coordinated work of multiple body systems, including balance, leg movement, foot-ground contact, and forward center of gravity. These include the skeleton, muscles, nervous system, cardiovascular system, and respiratory system.
Walking encompasses more than just walking; it also encompasses household chores like cooking, washing clothes, and sweeping. Throughout this process, the cardiovascular system supplies muscles with oxygen and nutrients while also removing metabolic waste. The respiratory system regulates breathing rhythm to meet the body’s oxygen needs during exercise. For most people, walking 6,000 to 8,000 steps per day is a relatively suitable range (the average person walks about 1,600 steps per kilometer). Steps within this range can help improve cardiopulmonary function, enhance muscle strength, boost metabolism, relieve stress and anxiety, help manage weight, and reduce the risk of heart disease, hypertension, and stroke.
Thus, gait, speed, and endurance during walking provide clues to assessing health status and can reflect a person’s overall well-being. Therefore, by observing and analyzing walking, potential health issues can be identified promptly.
