Cardiac output (CO) assessment as a basic hemodynamic parameter has been of interest in exercise physiology, cardiology and anesthesiology. Non-invasive techniques available are technically challenging, and thus difficult to use outside of the clinical or laboratory setting. We propose a novel method of non-invasive CO assessment using a single upper arm cuff. The method uses the arterial pressure pulse wave signal acquired from the brachial artery during 20 second intervals of suprasystolic occlusion. This method was evaluated on a cohort of 12 healthy individuals (age of 27...

The purpose of this Current Opinion article is to focus on the appropriate use of the terms 'aerobic'- and 'anaerobic'-exercise in sports medicine, in order to try to unify their use across coaches/athletes and sport scientists. Despite the high quality of most of the investigations, the terms aerobic/anaerobic continue to be used inappropriately by some researchers in exercise science. Until late 2014, for instance, 14,883 and 6,136 articles were cited in PubMed, in the field of 'exercise science', using the words 'aerobic' or 'anaerobic', respectively...

Huntington disease (HD) is a relentlessly progressive neurodegenerative disorder with symptoms across a wide range of neurological domains, including cognitive and motor dysfunction. There is still no causative treatment for HD but environmental factors such as passive lifestyle may modulate disease onset and progression. In humans, multidisciplinary rehabilitation has a positive impact on cognitive functions. However, a specific role for exercise as a component of an environmental enrichment effect has been difficult to demonstrate...

The oxidant and antioxidant equilibrium is known to play an important role in equine medicine and equine exercise physiology. There are abundant findings in this field; however, not many studies have been conducted for reference ranges of oxidative stress biomarkers in horses. This study was conducted to determine the reference values of reactive oxygen metabolites (d-ROMs) and biological antioxidant potential (BAP) using blood samples from 372 (191 males, 181 females) Thoroughbred racehorse aged 2 to 5 (3...

Exercise testing is an important tool for determining baseline fitness as well as to diagnose limitations in performance. The Bruce protocol has become the standard for exercise testing protocol in many exercise physiology laboratories, but is rarely a suitable test for athletes who often have complex hemodynamic and metabolic demands during exercise required for practice and competition. We describe the approach for exercise testing beyond the Bruce protocol and focus on strategies to individualize the testing protocol to the metabolic demands of an athlete's sport...

An eccentric contraction involves the active lengthening of muscle under an external load. The molecular and neural mechanisms underpinning eccentric contractions differ from those of concentric and isometric contractions and remain less understood. A number of molecular theories have been put forth to explain the unexplained observations during eccentric contractions that deviate from the predictions of the established theories of muscle contraction. Postulated mechanisms include a strain-induced modulation of actin-myosin interactions at the level of the cross-bridge, the activation of the structural protein titin, and the winding of titin on actin...

PURPOSE: Intensive exercise is known to be accompanied by a rapid release of cell free DNA (cfDNA). The physiological significance of cfDNA release for performance diagnostics has not been studied. Here we analysed the release of cfDNA during bicycle exercise and its correlation with physiological parameters. METHODS: Eleven male athletes performed an incremental cycling test. Venous blood was collected before, immediately after exercise and after 90 minutes of recovery...

PURPOSE: Increases in cfDNA concentrations have recently been demonstrated to occur in a variety of exhausting and vigorous exercise settings. Here we assessed the association of cfDNA with exercise duration and intensity in a controlled test-retest setting of a regenerative up to moderate aerobic run. METHODS: In a pre-test the lactate threshold (LT) was determined in 13 subjects (range: 10.8-13.4 km/h) by means of a step-wise incremental running test. Speed of the two endurance runs was set to 9...

Stable isotope tracers have been invaluable assets in physiological research for over 80 years. The application of substrate-specific stable isotope tracers has permitted exquisite insight into amino acid, fatty-acid and carbohydrate metabolic regulation (i.e. incorporation, flux, and oxidation, in a tissue-specific and whole-body fashion) in health, disease and response to acute and chronic exercise. Yet, despite many breakthroughs, there are limitations to 'substrate-specific' stable isotope tracers, which limit physiological insight, e...

The present study evaluated awareness of the Canadian Society for Exercise Physiology's 2011 Canadian Physical Activity Guidelines for Adults and assessed correlates. Reported awareness of the physical activity (PA) guidelines was 12.9% (204/1586) of the total sample surveyed. More than half (55%) self-reported meeting PA guidelines of ≥ 150 min of moderate to vigorous PA per week. Awareness of PA guidelines was significantly related to participants' level of PA (χ(2) (1) = 30.63, p < 0.001, φ = -0.14), but not to any demographic variables...

This paper considers the environmental impact on well-being and performance in elite athletes during Olympic competition. The benefits of exercising in natural environments are recognized, but less is known about the effects on performance and health in elite athletes. Although some Olympic events take place in natural environments, the majority occur in the host city, usually a large densely populated area where low exposure to natural environments is compounded by exposure to high levels of air, water, and noise pollution in the ambient environment...

BACKGROUND: Patients with spinal cord injury (SCI) have a higher prevalence of cardiovascular diseases compared to the healthy population. Aerobic exercise training is one of the recommended treatments. However, literature regarding the effect of aerobic training on patients with SCI is scarce. This study evaluated changes in parameters of exercise physiology and serum myokines immediately after exercise and after a training program among patients with SCI. METHODS: Male patients with SCI and age- and sex-matched healthy individuals were recruited...

BACKGROUND: In 2012, a European initiative called Single Hub and Access point for pediatric Rheumatology in Europe (SHARE) was launched to optimise and disseminate diagnostic and management regimens in Europe for children and young adults with rheumatic diseases. Juvenile dermatomyositis (JDM) is a rare disease within the group of paediatric rheumatic diseases (PRDs) and can lead to significant morbidity. Evidence-based guidelines are sparse and management is mostly based on physicians' experience...

It has been known for centuries that regularly performed exercise has beneficial effects on metabolic health. Owing to its central role in locomotion and the fact that it accounts for a large majority of whole-body glucose disposal and fatty acid oxidation, the effects of exercise on skeletal muscle has been a central focus in exercise physiology research. With this being said it is becoming increasingly well recognized that both adipose tissue and liver metabolism are robustly modified by exercise, especially in conditions of obesity and insulin resistance...

BACKGROUND: More and better interprofessional practice is predicated to be necessary to deliver good care to the patients of the future. However, universities struggle to create authentic learning activities that enable students to experience the dynamic interprofessional interactions common in healthcare and that can accommodate large interprofessional student cohorts. We investigated a large-scale mandatory interprofessional learning (IPL) activity for health professional students designed to promote social learning...
