Physical Activity Can Add 5+ Years to Your Life, Study Finds
British Journal of Sports Medicine researchers have found yet another link between exercise and longevity
It’s no secret that physical activity leads to a healthier, longer life. But for those over, or at least getting close to the hill, this is especially true, a new study suggests.
Researchers working with the British Journal of Sports Medicine found that low physical activity (PA) is tied to increased mortality. The researchers used a predictive model based on device-measured PA risk estimates and a life-table model analysis to establish results. The life table used included 2019 United States population and 2017 mortality data. Participants were 40 years or older with PA levels based on data from the 2003-2006 National Health and Nutritional Examination Survey.
The study discovered that if all individuals were as active as the top 25% of the population, Americans over the age of 40 could live an extra 5.3 years on average. Dr. Mary Njeri Wanjau, who worked on the project, called the five-year figure “whopping” while referring to it on social media.
The trial also saw individuals in the lowest activity quartile experience the largest bump in lifetime per hour through PA as simple as walking. An additional hour of doing so could add roughly 6.3 hours of life expectancy, per the report.
While notable, these findings follow what we’ve heard from the industry at large, specifically regarding older individuals. Another study earlier this year found that weight training can offer long-term health benefits for individuals of a “retirement age.” While 40 is a long way from senior citizenry, an additional study also found that HIIT may improve cognitive health for those aged 65 to 86.
The British Journal of Sports Medicine also recently discovered a link between high cardiorespiratory fitness and reduced risk of Dementia. It published other findings this year from the University of Sydney explaining how a few minutes of vigorous, incidental PA a day can significantly reduce the risk of major cardiovascular events in middle-aged women who don’t engage in structured exercise.
