Going from low- to intermediate-fitness may prolong life
Improving cardiovascular fitness over time may prolong life, suggests a new study. Patients who started with low fitness levels but were able to improve to intermediate or high fitness levels reduced their risk of death during the study by roughly 40 percent, say the authors. Exercise capacity is measured during an exercise stress test, which is typically performed on a treadmill or stationary bike. Someone with a higher maximal exercise capacity is able to achieve a faster walking pace or climb more stairs before getting tired, lead author Clinton Brawner told Reuters Health in an email interview.
