These formulas take into consideration an individual's age, sex, BMI, substance use, relative levels of physical activity, and pathologic co-morbidites. In 2016, Nauman and Nes et al. demonstrated the added and unique utility of estimated cardiorespiratory fitness (eCRF) in predicting risk of cardiovascular disease and all-cause mortality. [14]
Other studies have shown that exercise-based rehabilitation at a moderate intensity in heart failure patients improves cardiorespiratory fitness and increases both exercise endurance capacity and VO2max (12–31% increase). [15] More recent studies have examined the effects of high-intensity exercise on patients with heart failure.
Whether you’re 25 and looking to shake up your strength-training routine (and get the jump on longevity), 45 years young and want to reinforce your frame so you can run marathons with your ...
