Perspectives of Professor Barry A. Franklin: no pill can enhance fitness

Abstract

In this special interview, Professor Barry A. Franklin shared key experiential and research-based insights on professional success, exercise-based cardiovascular therapy, and the impactful role of cardiorespiratory fitness in promoting long-term health outcomes. (a) Professional success is built on clearly defined written goals, consistent daily action, personal responsibility, a mindset of happiness, optimism, and gratitude, and exemplary service to others; (b) Outstanding academic and clinical careers require effective mentorship, strong communication skills, advanced training and continuing education, disciplined work habits, and proactive management of stress and health; (c) Aerobic and resistance training provide complementary benefits in combating cardiovascular disease, with aerobic exercise contributing most strongly to long-term survival; (d) Cardiorespiratory fitness or VO₂max (maximum volume of oxygen uptake), expressed as metabolic equivalents (METs), is a powerful, independent, and additive predictor of survival, with each 1-MET (one metabolic equivalent) increase associated with a mortality reduction of ~ 15%-17%; (e) Higher fitness levels significantly reduce the risk and improve the prognosis of heart failure with preserved ejection fraction and heart failure with reduced ejection fraction, independent of body mass index and traditional risk factors; (f) Although aerobic fitness declines rapidly with detraining, it is reversible, while muscle strength can be largely maintained with one resistance training session per week; (g) To date, no pharmacologic therapy can elicit the increases in metabolism needed to improve fitness, as well as the associated favorable adaptations, and safe, accessible activities such as stair climbing and daily walking provide substantial cardiovascular risk reduction.
