In a recent study of 1,387 seniors aged 70 to 100 years, seniors who exercised more frequently and more strenuously had a lower incidence of lower back pain (LBP). Participation in strenuous physical activity was not only associated with a lower incident of LBP, but also associated with a lower risk of having previously suffered from LBP lasting for more than 30-days. Researchers concluded, "Strenuous physical activity at least once a week is protective for incident LBP in seniors." All individuals, especially seniors, should visit their primary health care provider prior to initiating any exercise regimen or elevated physical activity.
