EKG and sports

There was a longstanding controversy on the role of resting ECG in the preparticipation examination in athletes, as well as in children and adolescent, in leisure time or top athletes. Besides other arguments, this was due to the limited validity, to the false positive and false negative findings often followed by a thorough clinical examination. However, recent studies from different research groups yielded a significant improvement in establishing ECG criteria in athletes discriminating normal from abnormal or pathological findings in athletes.This in addition is supported and improved by a software-based ECG device considering the new Seattle criteria. These new criteria from the Seattle conference reliably discriminate normal from abnormal findings. Frequent ECG findings in athletes, especially in those engaged in endurance sports showed sinus bradycardia, AV-block and signs of left ventricular hypertrophy.

Genetic polymorphisms in alpha-actinin 3 and adrenoceptor beta genes in Austrian elite athletes and healthy controls

Background: During the last years many studies were conducted to investigate the contribution of various genetic variants to endurance and sprint/power performance of elite athletes. Data on team sport athletes are missing to a large extent. Therefore, the aim of the study was to investigate the frequency of selected polymorphisms on elite athlete status in Austrian team sport (handball, soccer), endurance and power athletes as well as in healthy control subjects.

Sports Medicine in our four neighbour countries

It is indeed quite a challenge to define sports medicine in a way that suits the greatest number. The reason is that the speciality involves a wide scope of different healthcare measures for a very broad population, from professional athletes to recreative active individuals. It contains diagnostic, curative, rehabilitative and preventive medical measures, on the field, in the clinic and the medical office or even in the physiology laboratory. And this heterogeneity also concerns the physicians practicing – or pretending it! – sports medicine.

Challenges with the biological passport: from sampling to interpretation

In 2008, the World Anti-Doping Agency officially launched the biological passport. The first validated module to operate was the blood module to fight erythropoietin (EPO) and blood transfusion abuse. It has been quite efficient to catch some doped athletes, but above all, was very good in reducing the prevalence of doping. It is unclear if athletes stopped doping or have adapted and are taking micro doses of EPO or transfusing small blood volumes. More recently, the steroid module was released, but until now, the number of urine adverse passport cases is very low.

Physical activity and chronic low back pain

Non-specific chronic low back pain is a multifactorial pathology with a significant impact on quality of life. Physical activity is a major axis of treatment to improve pain and functional capacity through structured exercises, but also to fight against physical deconditioning. It is therefore advised to perform leisure time physical activity regularly and in an adapted way. There is no contraindication to practice sports activities but they should be performed with special attention not to increase the symptoms. This article aims to evaluate the effects of different types of physical activity in chronic low back pain to help the practitioner to advise at best his patients and prescribe appropriate physical activity, source of pleasure and health benefits.

From Cardiac Rehabilitation to Ambulatory Preventive Care: The Swiss Way

Over the last years, cardiac rehabilitation services have expanded their indication to include not just patients after myocardial infarction or surgery, but also a variety of non-acute cardiovascular disease (CVD) states like stable coronary artery disease, peripheral artery disease, neurovascular disease as well as asymptomatic patients with no history of CVD but with a constellation of cardiovascular risk factors, especially metabolic syndrome and diabetes mellitus. In 2015, 110 ambulatory cardiovascular prevention and rehabilitation programs existed in Switzerland: 57 for cardiac, 17 for peripheral artery disease and 36 for diabetes rehabilitation.

Physical activity and cognitive function in older persons

Strategies to improve cognitive aging are highly needed. Among those, promotion of exercise and physical activity appears as one of the most attractive and beneficial intervention. Indeed, results from basic and clinical studies suggest that exercise and physical activity have positive effects on cognition in older persons without cognitive impairment, as well as in those with dementia. Despite inconsistent results, aerobic exercise appears to have the strongest potential to enhance cognition. However, even limited periods of walking (45 minutes, three times a week, over a 6-month period) have also been shown to enhance cognition, particularly executive functions.

Sports and Ramadan – influence on endurance performance

The intermittent fasting of Ramadan could affect various aspects of body physiology and biochemistry important to athletic success. Sleep time may be shortened. Disturbance of psychomotor performance, impaired vigilance and slower reactions can be observed particularly during afternoon. Food intake is limited to night-time meals. Well disciplined athletes usually maintain energy balance unless daily energy expenditures are very high. Daytime fluid depletion is inevitable if athletes exercise in the heat.

Seasonal variation of vitamin D levels in Swiss athletes

Introduction: Vitamin D deficiency is very prevalent in world population and growing evidence shows that also athletes are affected. Vitamin D deficiency causes beside bone disorders, musculoskeletal pain, muscle weakness and is associated with many other health disorders. For athletes in particular it may impair training and performance, prolong recovery and increase risk of injury. We therefore analyzed vitamin D levels in Swiss athletes focusing on prevalence according to age, gender, seasonal variations, indoor or outdoor sports, sunscreen use and vitamin D supplementation. Methods: This study was performed in a convenient sample of 655 Swiss Olympic athletes over one year.

Iron Deficiency in sports – definition, influence on performance and therapy

Iron deficiency is frequent among athletes. All types of iron deficiency may affect physical performance and should be treated. The main mechanisms by which sport leads to iron deficiency are an increased iron demand, an elevated iron loss and a blockage of iron absorption due to hepcidin bursts. As a baseline set of blood tests, haemoglobin, haematocrit, mean cellular volume (MCV), mean cellular haemoglobin (MCH) and serum ferritin levels are the important parameters to monitor iron deficiency. In healthy male and female athletes >15 years, ferritin values <15µg/l are equivalent to empty, values from 15 to 30µg/l to low iron stores. Therefore a cut-off of 30µg/l is appropriate.
