As the global population ages, the rise in chronic conditions such as dementia, cardiovascular disease, and osteoporosis has made it increasingly important to focus on not just living longer, but living healthier. New research from the University of Sydney provides encouraging news for women in their middle years, suggesting it's never too late to benefit from physical activity.
A significant study tracking over 11,000 Australian women between the ages of 47 and 52 from 1998 to 2019 has highlighted the importance of maintaining a regular exercise routine. According to the study, women who met the physical activity guidelines of at least 150 minutes per week throughout the study period reported better physical health outcomes than those who did not.
The study's findings are particularly compelling for women who may not have prioritized physical activity earlier in life. Remarkably, women who began exercising consistently during their 50s showed physical health scores nearly on par with those who had been consistently active earlier in life. This group even scored three percentage points higher on physical tests than their peers who rarely or never met exercise guidelines.
These insights underscore the potential for significant health improvements even when regular physical activity is adopted later in life. According to lead author Binh Nguyen, an epidemiologist at the University of Sydney, starting to exercise in your 50s can effectively "turn back the clock" on your health, aligning with public health initiatives that promote midlife as a critical time for adopting a healthier lifestyle.
However, the study also noted that women who only began exercising in their 60s did not experience the same level of benefits by age 70, likely due to insufficient accumulation of physical activity to manifest evident health improvements. This highlights the advantage of starting a little earlier, during the 50s.
Regular exercise is widely acknowledged as a life-extending remedy, with many studies linking physical activity to reduced mortality rates. However, this study is among the few that specifically track the long-term health effects of maintaining an active lifestyle through aging.
While self-reported data on physical activity can sometimes be imprecise, the researchers controlled for various factors such as socioeconomic status, diet, and other health conditions, finding a consistent, albeit small, advantage to regular physical activity.
The implications of these findings are not limited to women. The researchers suggest that similar benefits could likely be observed in men, though further studies are needed to confirm this.
In summary, the study reinforces the message that adopting or maintaining an active lifestyle in midlife is crucial for sustaining good health into later years. With a modest increase in physical activity, individuals can significantly enhance their quality of life and reduce the risk of mortality, proving that it's never too late to start moving towards a healthier future.
