Competitive and elite sport often challenges the balance between health and performance, especially when it involves youth athletes. As Lausanne was getting ready to host the 2020 winter Youth Olympic Games, we had the opportunity to reflect on these challenges and on what they mean for sports medicine practitioners. Elite sport pushes athletes to the limit, be it through their own intrinsic drive to achieve ever more, or through the pressures of the multiple stakeholders around sport.
Life post Coronavirus disease (COVID-19) will not be same for anyone and like so many professions it will be a challenging time for physiotherapists and health care providers. A lot of practitioners are going through economic challenges because of the imposed lock down in various countries. As the situation recovers and more people resume their working life, we physiotherapists should be more concerned now while attending to our clients. As front-line practitioners, physiotherapists are more prone to have direct contact with patients affected with COVID-19.
Gendered norms, stereotypes and biases implicitly influence our thoughts, attitudes and behaviours. These often lead to gender inequity, a phenomenon inherent in society and reflected in its various contexts. The increasing awareness of this inequity is leading to reflection and changes in society as a whole and its communities, organisations and institutions. In scientific disciplines, gender inequity has been, and still is, a point of discussion and consideration. In many cases, these discussions have led to positive and sustainable changes at both a structural as well as a policy level. This opinion piece discusses gender inequity in the context of sport science and, in particular, sport medicine in Switzerland.
Summary: Muscle damage as well as recurrent and serious infections especially to the end of the playing period in team sport or to the end of preparation for competition in endurance or single sport are the most common symptoms in elite sport demolishing optimal training results. Are VitaminD deficiency responsible for these symptoms in elite sport.
This interview was conducted by Dr Boris Gojanovic after the Lausanne 2020 Youth Olympic Games.
Richard, can you please introduce yourself, as a medical doctor and an athlete.
I am the medical and scientific director for the IOC and I started off in life as a rower. As an athlete, I had the privilege to compete in the 1984 Olympic Games in Los Angeles, and I won a gold medal there.
Back pain is common among elite cyclists. Experiences of athletes and observations of coaches show that it may influence training quality and sometimes even limit performance during competition. Therefore the following study questions were investigated: 1) How many athletes of the Swiss cycling national teams suffer back pain during training or competition? 2) How good is athletes’ core strength? 3) What correlation exists between back pain and core strength? 4) Does an intensified core strength training reduce back pain?
A total of 111 elite cyclists, 45 athletes (38 m, 7f; 19.6 ± 3.5y) of technical disciplines (BMX, Trial, Downhill, 4X) and 66 athletes (39 m, 27f; 19.5 ± 5.8y) of endurance disciplines (road, MTB, Cyclo-cross) all members of Swiss cycling national teams, took part in in the study.
The Youth Olympic Games were introduced in 2010 with the aim to bring young athletes not only an experience of competition on the world stage, but also to help them learn about the Olympic values, explore other cultures and develop the skills to become true ambassadors. The Lausanne 2020 Games provided an excellent opportunity to develop innovative concepts for health promotion and sports-related prevention. The enthusiasm across various sectors of society (political, academic and economy) empowered us to bring together multiple skills to materialize the IOC’s pledge.
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.
Sport medicine is not offered as a separate specialist medical training in the German-speaking countries, and for this reason Danube University Krems has aimed to establish an innovative, interdisciplinary master’s program. The goal is to offer physicians a practice-oriented continuing education that covers a broad spectrum.
This article described the clinical examination of the lower extremity during a pre-participation screening in regard of sports ability, presence of injuries and musculoskeletal disorders as well as predisposing risk factors for injuries and prevention. It divided into global static and dynamic testing but also isolated analysis of joint function.
Background: The development of Mountain Ultra Marathon (MUM) raises several questions to health professionals, regarding the short or long-term consequences on the health of participants.
Objective: to present the main acute and long-term effects of MUM on the main health issues usually studied among runners.
Methods: Pragmatic review of the literature, including grey literature from the medical staff of the races, notably the Ultra-trail du Mont Blanc.
Concentric and eccentric muscle work is characterized through different biochemical activating cascades. Concentric contraction is characterized by an ATP O2 coupling dependent interaction of the myofibril proteins Aktin and Myosin. In eccentric contraction, according to the Winding-filament hypothesis, a rotation movement around the thin filament is caused which is ATP independent. In addition, the processes of motor anticipation vary greatly between the two. This leads to the aim of the study: What are the differences in concentric versus eccentric muscle work concerning anticipation, perception and execution.
Chronic exertional compartment syndrome of the lower leg accounts for approximately 75% of sports-related chronic leg pain. Nevertheless, the exact and timely recognition in athletes might pose a great challenge to sports physicians. Among a variety of possible differential diagnoses such as tenosynovitis, stress fractures, periostalgia, or popliteal artery entrapment syndrome the physician has to be able to identify the correct entity as promptly as possible.
Objectives: The objectives of this study were to observe the developmental trajectories of motivation types among young children from 8 to 12 years using a more comprehensive scale of physical education motivation. We also tested the relations between these trajectories and objective physical activity during this period.
This observational study used field tests to investigate the association between physiological parameters and rowing performance in athletes during ergometer and on-water Swiss national competitions. 25 Participants between 15 and 35 years who compete at national level were recruited among different clubs. We assessed anthropometric parameters such as weight, height, aerobic capacity during an incremental test on a rowing ergometer, anaerobic capacity during an on rowing ergometer Wingate test and lower limb strength and power during countermovement- and squat jumps.
While addictive disorders involving substances are well researched, the field of behavioral addictions, including exercise addiction, is in its infancy. Although exercise addiction is not yet recognized as a psychiatric disorder, evidence for the burden it imposes has gained attention in the last decade. Characterised by a rigid exercise schedule, the prioritization of exercise over one’s own health, family and professional life, and mental wellbeing, and extreme distress when exercise is halted, the phenomenon shares many feature with substance use disorders.
A common complaint in the musculoskeletal system is the anterior knee pain (AKP) or the so called patellofemoral pain syndrome (PFPS). The large number of contributing factors that lead to the symptoms make a proper diagnosis and targeted physiotherapeutic treatment management difficult. With regard to symptom-complex-oriented physiotherapeutic care, the question arises as to which therapy methods should be used for individuals with AKP. In order to be able to identify adequate physical therapy methods, an understanding of the clinical condition and the chosen treatment method is essential. This article aims to present a heuristic model of objectives and situational physiotherapeutic treatment methods.
Physical inactivity constitutes the fourth leading cause of death globally. Health systems are being called to respond to the epidemic of non-communicable diseases (NCDs) and help deliver on the promise of prevention approaches. Substantial evidence exists in support of multi-prong physical activity counseling, prescription and referral strategies, in particular those linking clinical and community-based resources, to help increase physical activity (PA) levels. In late 2007, the “Exercise is Medicine” (EIM) initiative was established by the American College of Sports Medicine to institutionalize PA promotion into the US healthcare system.
The goal of the present study was the analysis of the effects of two endurance training interventions (HIIT versus POL) over a period of 5 weeks on 16/17 year old sport major students. The study was integrated in regular P.E. lessons.
In addition to the training load, daily changes of easily measurable cardiologic parameters were monitored in order to assess their validity in predicting endurance performance.
The students conducted 12 training sessions in two groups. With pre- and post-tests the endurance capacity was determined via Luc Léger’s shuttle run test.
Exercise testing in athletes and patients is an important and valuable diagnostic tool in the hand of the physician and sport scientist. A close collaboration between sport scientist and sport physician creates a win-win-win-situation for athletes and patients and professionals equally. According to the demands of the sport an incremental lactate threshold test (determination of the anaerobic threshold), testing of VO2max and performance at VO2max, and a testing of aerobic capacity (performance at competitional level) are the tests of choice. All tests need to be valid, reliable and sport specific. Sport specificity in testing is for practical purposes the most important.
