Our population is ageing. By 2030, the number of Americans over age 65 years is expected to reach 74.1 million.1 Maintaining physical activity levels will become increasingly important to mitigate the effects of chronic disease in our ageing patient population.
The American College of Sports Medicine recommends 150 min per week of moderate intensity exercise.2 A subset of ageing athletes are meeting and exceeding recommended physical activity levels, with an increasing number of athletes ages 40 years and older participating in Ironman competitions, ultracycling events, ultramarathons and long-distance inline skating.

However, exercise alone cannot overcome physiological age-related declines in bone density. Bone density peaks in the third decade of life, and then steadily declines,3 4 placing older athletes at risk for …
