—Vince Lombardi American-style football (ASF) is the most popular organized team sport in the United States, with% 1 million high school, 1 70 000 collegiate, 2 and 2000 professional participants annually. 3, 4 Although youthful competitive athletes are classically regarded as the paradigm of health and vitality, uncertainties surrounding the long-term health implications of ASF participation have recently become a topic of considerable interest and controversy. 5, 6 Specifically, concerns about the impact of ASF participation on cardiovascular and neurocognitive health7 have generated lively debates in the scientific literature, in the mainstream media, and within governing bodies that oversee ASF rules and regulations. The physiology inherent in ASF participation is complex and differs from most other popular forms of sport. Factors including high loads of static hemodynamic stress, relatively low amounts of aerobic conditioning, deliberate body mass gain, psychological stress, and routine NSAID8 use carry potential implications for cardiovascular health. In healthy nonathletic populations, early onset cardiovascular risk and attendant subclinical pathology at ages typical of ASF athletes predict later life cardiovascular morbidity and mortality. 9–11Although this phenomenon has not been firmly established among ASF participants, a growing body of observational data documents associations among large body mass, 12, 13 early life hypertension, 12, 14 and subclinical pathologic cardiovascular phenotypes15–18 in ASF athletes. In addition, epidemiologic outcomes data from former professional ASF athletes suggest accelerated cardiovascular mortality among former linemanposition players. 19, 20 The precise relationship between early life ASF participation and subsequent cardiovascular health remains incompletely understood; however, multiple lines of evidence suggest that ASF participation may impart increased risk for the development of cardiovascular disease. This review was constructed to delineate our contemporary understanding of cardiovascular health among ASF participants, a population that is commonly encountered in clinical cardiovascular practice. To do so, a comprehensive and broad scientific literature search targeting ASF and cardiovascular health was conducted. Studies matching this description were reviewed in detail and referenced in this review. The basic physiology accompanying ASF participation is initially discussed. Next, prior studies of high school, collegiate, and professional ASF cohorts that describe cardiovascular risk factor profiles, cardiovascular phenotypes, and outcomes data are detailed, along with an emphasis on key limitations of the currently available data. Finally, a framework for future research imperatives and clinical strategic approaches for cardiovascular specialists is proposed.
