Transient exercise-related symptoms are common in children and adolescents and only rarely reflect underlying cardiac and pulmonary disease processes. Most symptoms occurring during exercise reflect changes related to normal exercise physiology, changes in level of competition, and musculoskeletal and developmental factors. A rational approach to screening for potentially life-threatening cardiac conditions and exercise-induced bronchospasm is important to minimize the risk of misdiagnosis and to keep the young athlete active.

Using Near-Infrared Spectroscopy Wearable Devices to Identify Central Versus Peripheral Limitations During Exercise.

Article Synopsis
- The gold standard for measuring aerobic capacity in athletes is the VO2-max test, but it doesn't provide insights into muscular metabolic changes.
- Near-infrared spectroscopy (NIRS) is a new technology that measures local oxygen levels in tissues, helping assess both breathing costs and muscle workload during exercise.
- By analyzing changes in oxygen levels and tissue saturation, coaches and exercise physiologists can identify limitations in endurance training, improving athletic performance through tailored strategies.
Identifying limitations to exercise with incremental cardiopulmonary exercise testing: a scoping review.

Cardiopulmonary exercise testing (CPET) is a comprehensive and invaluable assessment used to identify the mechanisms that limit exercise capacity. However, its interpretation remains poorly standardised. This scoping review aims to investigate which limitations to exercise are differentiated by the use of incremental CPET in literature and which criteria are used to identify them.

Article Synopsis
- The study investigates factors that limit exercise in patients with hypertrophic cardiomyopathy (HCM) by using combined stress echocardiography and cardiopulmonary exercise testing.
- It compares 36 HCM patients with 29 age and sex-matched controls, finding significant differences in cardiac function and pulmonary pressures during exercise.
- Results show worsened diastolic function, increased pulmonary artery pressures, and reduced oxygen consumption in HCM patients compared to controls, indicating impaired exercise capacity in this population.

Failure to recover following severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) may have a profound impact on individuals who participate in high-intensity/volume exercise as part of their occupation/recreation. The aim of this study was to describe the longitudinal cardiopulmonary exercise function, fatigue, and mental health status of military-trained individuals (up to 12-mo postinfection) who feel recovered, and those with persistent symptoms from two acute disease severity groups (hospitalized and community-managed), compared with an age-, sex-, and job role-matched control. Eighty-eight participants underwent cardiopulmonary functional tests at baseline (5 mo following acute illness) and 12 mo; 25 hospitalized with persistent symptoms (hospitalized-symptomatic), 6 hospitalized and recovered (hospitalized-recovered); 28 community-managed with persistent symptoms (community-symptomatic); 12 community-managed, now recovered (community-recovered), and 17 controls.
