Palpitations in athletes: diagnosis, workup and treatment.

Palpitations are a common reason for athletes to seek medical care. Although often benign, palpitations may serve as a harbinger for underling cardiac pathology. Given the unique challenges in this population, this review will serve to discuss the basic underlying pathophysiology, which may predispose athletes to palpitations. In addition, we will review the aetiologies, diagnostic evaluation, management and counselling strategies for some of the most common diagnoses seen in athletes.

Osteoarthritis, Osteophytes, and Enthesophytes Affect Biomechanical Function in Adults With X-linked Hypophosphatemia.

CONTEXT: X-Linked hypophosphatemia (XLH) is a lifelong metabolic disease with musculoskeletal comorbidities that dominate the adult clinical presentation. OBJECTIVE: The adult XLH disorder has yet to be quantified on the basis of the physical and functional limitations that can affect activities of daily living. Our goal was to report the impact of the musculoskeletal manifestations on physical function. DESIGN AND SETTING: Musculoskeletal function was evaluated by validated questionnaires and in an interdisciplinary clinical space where participants underwent full-body radiologic imaging, goniometric range of motion (ROM) measurements, general performance tests, and kinematic gait analysis. PATIENTS: Nine adults younger than 60 years with a diagnosis of XLH and self-reported musculoskeletal disability, but able to independently ambulate, were selected to participate. Passive ROM and gait analysis were also performed on age-approximated controls to account for differences between individual laboratory instrumentation. RESULTS: Enthesophytes, degenerative arthritis, and osteophytes were found to be consistently bilateral and diffusely present at the spine and synovial joints across participants, with predominance at weight-bearing joints. Passive ROM in adults with XLH was decreased at the cervical spine, hip, knee, and ankle compared to controls. Gait analysis relative to controls revealed increased step width, markedly increased lateral trunk sway, and physical restriction at the hip, knees, and ankle joints that translated into limitations through the gait cycle. CONCLUSIONS: The functional impact of XLH musculoskeletal comorbidities supports the necessity for creating an interprofessional health-care team with the goal of establishing a longitudinal plan of care that considers the manifestations of XLH across the lifespan.

Electrocardiographic changes following six months of long-distance triathlon training in previously recreationally active individuals.

Background: Clinical electrocardiographic (ECG) guidelines for athlete's heart are based upon cross-sectional data. We aimed to longitudinally evaluate the influence of endurance training on the ECG and compare the prevalence of ECG abnormalities defined by contemporary criteria. Methods: A group of 66 training-naïve individuals completed a six-month training programme with resting ECGs and cardiopulmonary exercise tests performed at baseline, two and six months. Data were analysed using repeated measures analysis of variance and the prevalence of ECG abnormalities compared between proposed criteria. Results : Maximal oxygen consumption increased from 45.4 ± 7.1 to 50.3 ± 7.1 ml·kg-1·min-1 (p < 0.05) pre-to-post training. ECG changes included, bradycardia (60 ± 12 vs. 53 ± 8 beats·min-1; p < 0.05), shorter P wave duration (106 ± 10 vs. 103 ± 11 ms; p < 0.05), reduced QTc (413 ± 27 vs. 405 ± 22 ms; p < 0.05), and increased left ventricular Sokolow-Lyon index (2.45 ± 0.66 vs. 2.62 ± 0.78 mV; p < 0.05). 85% of individuals showed ≥1 'training-related' ECG finding at six months vs. 68% at baseline. Using the 2013 Seattle Criteria, 4 ECGs were 'abnormal' at baseline and 3 at month six vs. 2 at baseline and 1 at month six, using the 2017 International Consensus. Prevalence of 'borderline' findings did not increase with training (11% at baseline and six months). Conclusion: Six-months endurance training leads to a greater prevalence of 'training-related' but not 'borderline' or 'training-unrelated' ECGs. 'Borderline findings' may not necessarily represent training-related cardiac remodelling in novice athletes following a six-month training intervention. KEY MESSAGES This study aimed to assess the longitudinal ECG changes following six months of endurance training, in training-naïve individuals, and whether these ECG changes support the revisions made to the recent 2017 international consensus criteria. The prevalence of 'training-related' findings were increased with six months of endurance training, however the prevalence of the revised 'borderline' criteria, according to the 2017 international consensus, did not increase and the associated quantitative ECG data (e.g. P-wave amplitude, QRS axis and QRS duration) remained unchanged. Further clinical consideration may be warranted for individuals within the early phase of exercise engagement presenting with 'borderline' ECG abnormalities, defined by the International criteria.

Exercise and Cardiovascular Risk among Masters Athletes with Type 2 Diabetes.

PURPOSE OF REVIEW: This review was designed to provide a scientific and clinical framework for the care of physically active men and women with an emphasis on the management of T2DM. RECENT FINDINGS: The preventative and therapeutic benefits of physical activity (PA) on adult onset or Type 2 Diabetes Mellitus (T2DM) are well established. Individuals diagnosed with or are at risk for T2DM should be counseled and maximally supported to pursue an active or athletic lifestyle. Optimally, this translates into the adoption of an athletic lifestyle. "Masters athletes", men and women above the age of 35 who regularly train for and/or participate in competitive sport, represent a rapidly growing segment of the population. Although the high level of exercise characteristic of this population has numerous health benefits, it does not confer immunity from T2DM or cardiovascular (CV) disease. Providing effective care for men and women above the age of 35 who regularly train for and/or participate in competitive sport requires an understanding of the interplay between basic exercise physiology and the pathogenesis of insulin resistance.
