RESUMEN
BACKGROUND: An athlete's career inevitably goes through periods of forced physical exercise interruption like a knee injury. Advanced echocardiographic methods and cardiopulmonary exercise testing (CPET) are essential in evaluating athletes in the period elapsing after the injury. However, the feasibility of a maximal pre-surgery CPET and the capacity of resting advanced echocardiographic techniques to predict cardiorespiratory capacity still need to be clarified. METHODS: We evaluated 28 non-professional athletes aged 18-52, involved in prevalently aerobic or alternate aerobic/anaerobic sports activities, affected by a knee pathology with indications for surgical treatment. The evaluation was performed at rest by trans-thoracic echocardiography, including global longitudinal strain (GLS) and myocardial work (MW) assessment, and during exercise by CPET. RESULTS: The percent-predicted peak oxygen consumption (peak VO

Routine or vigorous training, particularly in competitive and elite athletes practicing dynamic sports, leads to a constellation of structural and functional cardiovascular adaptations, facilitating an increased capacity to deliver oxygen to the working muscles during sustained physical exertion. Cardiopulmonary exercise testing is the most accurate and objective method to assess performance in athletes. Although still underutilized, it provides a window into the unique cardiovascular response to exercise in athletes, integrating parameters obtained by the traditional exercise test with breath-by-breath analysis of oxygen consumption, carbon dioxide production, ventilation, and other derived parameters. This review aimed to describe the several applications of cardiopulmonary exercise testing in athletes with a principal focus on the ability to identify cardiovascular adaptations and differentiate an athlete's heart from early cardiomyopathy. In this context, cardiopulmonary exercise testing provides many applications involving exercise physiology in athletes, allowing a precise evaluation of cardiovascular efficiency, the entity of the adaptations, the response to a training program, and identifying early modifications that could reveal early cardiomyopathy. Therefore, thanks to its several applications, this pivotal test allows us to obtain essential information about the athlete's physiology and differentiate between the expected response of a trained athlete from early cardiomyopathy.
