BACKGROUND: Physical activity screening prior to starting a physical activity program is important to identify if there are any underlying health conditions. However, many older adults do not complete such assessments prior to beginning their physical activity program. This project compared the Canadian Society for Exercise Physiology's newly developed Get Active Questionnaire (GAQ) to a standardized exercise stress test in terms of screening out versus screening in false positive GAQ tests...

Regenerative medicine is a novel discipline that both excites undergraduates and may be used as a vehicle to expose students to scientific concepts and opportunities. The goal of this article is to describe the implementation of a National Science Foundation-funded Targeted Infusion Project in which underrepresented minority undergraduates are exposed to laboratory-bench skills and summer research opportunities that they may not have encountered otherwise. A 3-wk infusion of laboratory-bench and data presentation skills, in the context of a regenerative medicine/bioengineering project, aimed to engage students and expose them to opportunities as summer researchers and teaching assistants...

Lactate (La-) has long been at the center of controversy in research, clinical, and athletic settings. Since its discovery in 1780, La- has often been erroneously viewed as simply a hypoxic waste product with multiple deleterious effects. Not until the 1980s, with the introduction of the cell-to-cell lactate shuttle did a paradigm shift in our understanding of the role of La- in metabolism begin. The evidence for La- as a major player in the coordination of whole-body metabolism has since grown rapidly. La- is a readily combusted fuel that is shuttled throughout the body, and it is a potent signal for angiogenesis irrespective of oxygen tension...

Maintaining a positive iron balance is essential for female athletes to avoid the effects of iron deficiency and anaemia and to maintain or improve performance. A major function of iron is in the production of the oxygen and carbon dioxide carrying molecule, haemoglobin, via erythropoiesis. Iron balance is under the control of a number of factors including the peptide hormone hepcidin, dietary iron intake and absorption, environmental stressors (e.g. altitude), exercise, menstrual blood loss and genetics. Menstruating females, particularly those with heavy menstrual bleeding are at an elevated risk of iron deficiency...

Blended learning has become increasingly common in higher education. Recent findings suggest that blended learning achieves better student outcomes than traditional face-to-face teaching in gross anatomy courses. While face-to-face content is perceived as important to learning there is less evidence for the significance of online content in improving student outcomes. Students enrolled in a second-year anatomy course from the physiotherapy (PT), exercise physiology (EP), and exercise science (ES) programs across two campuses were included (n = 500)...

Rationale: Mitochondria play a dual role in the heart, responsible for meeting energetic demands and regulating cell death. Paradigms have held that mitochondrial fission and fragmentation are the result of pathologic stresses such as ischemia, are an indicator of poor mitochondrial health, and lead to mitophagy and cell death. However, recent studies demonstrate that inhibiting fission also results in decreased mitochondrial function and cardiac impairment, suggesting that fission is important for maintaining cardiac and mitochondrial bioenergetic homeostasis...

OBJECTIVES: To examine school- and student-level correlates of physical activity. METHODS: Cross-sectional Year 2 data collected from 45 298 grade 9-12 students attending 89 secondary schools in the COMPASS study were examined using multi-level modelling to predict the likelihood of students a) achieving 60 minutes of moderate to vigorous physical activity (MVPA) daily; and b) achieving the Canadian Society for Exercise Physiology (CSEP) activity guideline for youth (60 minutes/MVPA daily, vigorous physical activity at least three days in a week, and resistance training at least three days in a week)...

Graduate student attitudes (n = 28) were assessed before and after participation in interprofessional practitioner education (IPE). Twenty-eight graduate students participated (14 mental health nursing, 6 pharmacy, 4 nutrition, 4 exercise physiology); most had at least some health care experience. Posttest scores indicated gains on a majority of constructs measured. These results suggest that online-blended IPE content yields gains in team skills and attitudes. This study adds to a very small body of literature on IPE in graduate programs...

BACKGROUND: Pure exercise intolerance associated with exclusive affection of skeletal muscle is a very rare phenotype of patients with mitochondrial myopathy. Moreover, the exercise intolerance in these rare patients is yet not well explored, as most of known cases have not been assessed by objective testing, but only by interview. We report a patient with a mitochondrial DNA (mtDNA) mutation that gives rise to an exclusive myopathy associated with exercise intolerance and ophthalmoplegia...

REVIEW
Robert Andrew Robergs
A connection has been made to the possible role of the central governor model (CGM) to be a paradigm shift within the exercise sciences. Unfortunately, very little evidence was presented to support this notion, and a narrow view of scientific philosophy was used to reflect on the role of the CGM in understanding exercise physiology and the pursuit of a more ideal scientific method. When contrasting the scientific philosophies of Kuhn to Popper, and applying the tenant of falsification to the research and commentary on the CGM, it is probable that the scholarship pertaining to the CGM adheres more to pseudoscience than science...

Referees are an integral part of soccer and their performance is fundamental for regular match flow, irrespective of the competition level or age classes. So far, scientific interest was mainly limited to aspects of exercise physiology and match performance of soccer referees, whereas recommendations for nutrition were adopted from active professional soccer. In contrast to elite soccer players most referees are non-professional and engaged in different occupations. Furthermore, elite referees and soccer players differ in regard to age, body composition, aerobic capacity and training load...

Mitochondrial disorders are genetically determined metabolic diseases due to a biochemical deficiency of the respiratory chain. Given that multi-system involvement and disease progression are common features of mitochondrial disorders they carry substantial morbidity and mortality. Despite this, no disease-modifying treatments exist with clear clinical benefits, and the current best management of mitochondrial disease is supportive. Several therapeutic strategies for mitochondrial disorders are now at a mature preclinical stage...

In response to Armstrong's recent Special Topics review of "Top 10 Research Questions Related to Youth Aerobic Fitness," this commentary revisits some of the points raised, particularly in relation to the question of whether a child‒adult trainability difference does indeed exist. Discussed are the validity of much of the existing pediatric maximal oxygen consumption data upon which trainability conclusions are drawn, why differential trainability is likely a fact rather than a doubt, a reasoned novel approach to explaining the phenomenon, and how that explanation can bear upon and answer several of the other raised questions...

Traditionally, the main indication for cardiopulmonary exercise testing (CPET) in heart failure (HF) was for the selection of candidates to heart transplantation: CPET was mainly performed in middle-aged male patients with HF and reduced left ventricular ejection fraction. Today, CPET is used in broader patients' populations, including women, elderly, patients with co-morbidities, those with preserved ejection fraction, or left ventricular assistance device recipients, i.e. individuals with different responses to incremental exercise and markedly different prognosis...

Betaine (N-trimethylglycine), a common osmolyte, has received attention because of the number of clinical reports associating betaine supplementation with improved cognition, neuroprotection and exercise physiology. However, tissue analyses report little accumulation of betaine in brain tissue despite the presence of betaine/GABA transporters (BGT1) at the blood brain barrier and in nervous tissue, calling into question whether betaine influences neuronal function directly or indirectly. Therefore, the focus of this study was to determine what capacity nervous tissue has to accumulate betaine, specifically in the hippocampus, a region of the brain associated with learning and memory and one that is particularly susceptible to damage (e...

An article by Margaritelis et al.,(1) (this issue) addresses an important issue in exercise physiology, as it is the actual role of reactive oxygen and nitrogen species (RONS) in exercise-induced adaptations in humans. The authors designed a procedure that allowed them to avoid the use of exogenous anti-oxidants and redox agents that will normally alter metabolism and have multiple undesired effects. We discuss here in the context of the necessary balance between the beneficial role of reactive oxygen and nitrogen species as intracellular signals for muscle adaptation and the deleterious effects of these species in oxidative stress...
