BACKGROUND: In the primary and secondary prevention of civilization diseases, regular physical activity is recommended in international guidelines to improve disease-related symptoms, delay the progression of the disease, or to enhance postoperative outcomes. In the preoperative context, there has been a paradigm shift in favor of using preconditioning concepts before surgery. Web-based interventions seem an innovative and effective tool for delivering general information, individualized exercise recommendations, and peer support...

Sports in Patients with Heart Disease: What Should Be Recommended? Abstract. Sports is recommended in the European guidelines for the prevention and initial treatment of many cardiovascular diseases as well as the metabolic syndrome. However, the individually recommended intensity and duration of physical activity that unfolds the maximal protective effects in terms of prevention, largely differs. Indeed, a J-curve relationship with regard to exercise training has been postulated, with the assumption that too much sports is equally harmful or potentially even more harmful than too little sports...

PURPOSE: The assessment of power changes after fatiguing exercise provides important additional information about neuromuscular function compared to traditional isometric measurements, especially when exploring age-related changes in fatigability. Therefore, the aim of this review was to explore the effects of age on neuromuscular fatigue (NMF) when measured in isometric compared with dynamic contractions. The importance of central and peripheral mechanisms contributing to age-related NMF were discussed...

There has been a recent resurgence in debate about methods for statistical inference in science. The debate addresses statistical concepts and their impact on the value and meaning of analyses' outcomes. In contrast, philosophical underpinnings of approaches and the extent to which analytical tools match philosophical goals of the scientific method have received less attention. This short piece considers application of the scientific method to "what-is-the-influence-of x-on-y" type questions characteristic of sport and exercise science...

The exercise tolerance of Fontan patients is poorer than that of healthy people. Some previous studies reported that exercise tolerance can be improved in this population by cardiac rehabilitation. This study aimed to determine the factors associated with peak oxygen uptake (VO2) and to subsequently clarify the correlation between participation in sports club activities and variables related to exercise tolerance. Cardiopulmonary exercise tests were performed by 115 Fontan patients aged between 6 and 20 years...

Human beings harbor clusters of bacteria in different parts of the body, such as the surface or the deep layers of the skin, the mouth, the lungs, the intestine, the vagina, and all the surfaces exposed to the outer world. The majority of microbes resides in the gut, have a weighty influence on human physiology and nutrition and are vital for human life. There is growing evidence showing that the gut microbiota plays important roles in the maturation of the immune system and the protection against some infectious agents...

Many hamstring injuries that occur during physical activity occur while the muscles are lengthening, during eccentric hamstring muscle actions. Opposite of these eccentric hamstring actions are concentric quadriceps actions, where the larger and likely stronger quadriceps straighten the knee. Therefore, to stabilize the lower limbs during movement, the hamstrings must eccentrically combat against the strong knee-straightening torque of the quadriceps. As such, eccentric hamstring strength expressed relative to concentric quadricep strength is commonly referred to as the "functional ratio" as most movements in sports require simultaneous concentric knee extension and eccentric knee flexion...

In 1975, Morganroth and colleagues reported that the increased left ventricular (LV) mass in highly trained endurance athletes versus nonathletes was primarily due to increased end-diastolic volume while the increased LV mass in resistance trained athletes was solely due to an increased LV wall thickness. Based on the divergent remodelling patterns observed, Morganroth and colleagues hypothesised that the increased "volume" load during endurance exercise may be similar to that which occurs in patients with mitral or aortic regurgitation while the "pressure" load associated with performing a Valsalva manoeuvre (VM) during resistance exercise may mimic the stress imposed on the heart by systemic hypertension or aortic stenosis...

Sport and exercise participation exert a positive effect on numerous aspects of individuals' health. Although sport and exercise leaders have generally been observed to play a key role in shaping group members' behavior, our understanding of their impact on group members' attendance in sport and exercise sessions is limited. To address this, and building on promising findings in other domains, we examined associations between perceptions of sport and exercise leaders' engagement in social identity leadership, group identification, and attendance...

Background -T-wave inversion (TWI) is common in patients with cardiomyopathy. However, up to 25% of athletes of African/Afro-Caribbean descent (black athletes) and 5% of white athletes also have TWI of unclear clinical significance despite comprehensive clinical evaluation and long-term follow-up. The aim of this study was to determine the diagnostic yield from genetic testing, beyond clinical evaluation, when investigating athletes with TWI. Methods -We investigated 50 consecutive asymptomatic black and 50 white athletes aged 14-35-years-old with TWI and a normal echocardiogram who were referred to a UK tertiary center for cardiomyopathy and sports cardiology...
