Physiol Rep 2021 May;9(9):e14787

Department of Muscle and Bone Metabolism, Institute of Aerospace Medicine, German Aerospace Center (DLR), Cologne, Germany.

Prolonged exposure to microgravity during spaceflights leads to severe deterioration in the physical performance of astronauts. To understand the effectiveness of existing in-flight daily countermeasures and to plan exercise onboard the International Space Station, we compared supine treadmill running to traditional upright treadmill running on earth. Specifically, we assessed the cardiorespiratory responses to conventional upright running to the responses to supine treadmill running under 0. Read More

Acetabular Stress Fracture in a Healthy Male Amateur Endurance Runner. A Case Report.

J Orthop Case Rep 2020 May-Jun;10(3):85-87

Department of Orthopaedic Surgery, San Fernando General Hospital, Independence Ave, San Fernando, Trinidad, West Indies.

Introduction: Stress fractures are overuse injuries resulting from repetitive submaximal loading of a bone. Acetabular stress fractures while highly uncommon can occur in those undergoing intense endurance training as is the case with military recruits. Diagnosis of this injury can be dubious at times, with magnetic resonance imaging (MRI) being the most sensitive diagnostic tool considering the lower sensitivity of plain film radiography.

The effects of exercise training on Kinesin and GAP-43 expression in skeletal muscle fibers of STZ-induced diabetic rats.

Sci Rep 2021 May 5;11(1):9535. Epub 2021 May 5.

Department of Physical Education and Sport Sciences, Faculty of Literature and Human Sciences, Lorestan University, Khoramabad, Iran.

Kinesin-1 and Growth Associated Protein 43 (GAP-43) localization in muscle fiber are crucial for proper skeletal muscle hypertrophy. To evaluate this assumption, we investigated the beneficial effects of endurance training on GAP-43 and Kinesin Family Member 5B (KIF5B) expression in gastrocnemius muscle of streptozotocin (STZ)-induced diabetic rats. Fifty-two male rats were randomly divided into four groups: healthy control (C), healthy trained (T), diabetic control (DC) and diabetic trained (DT). Read More

Pemmican, an endurance food: Past and present.

Meat Sci 2021 Apr 24;178:108526. Epub 2021 Apr 24.

Sherbrooke Research and Development Centre, Agriculture and Agri-Food Canada, 2000 College Street, Sherbrooke, Quebec J1M 0C8, Canada.

Pemmican is a meat product principally comprised of dried meat and fat that has served as a source of sustenance in cold, harsh climates and/or a means of preservation of meat for some Indigenous peoples, fur traders, polar explorers, military and police. Pemmican is acclaimed for its high nutrient density and long shelf life. However, for a meat product that has historically played a significant role and is often cited as the ultimate endurance food, there is a surprising paucity of scientific literature. Read More

Quantification of testosterone-dependent erythropoiesis during male puberty.

Exp Physiol 2021 May 4. Epub 2021 May 4.

Departamento de Biología, Facultad de Ciencias, Universidad Nacional de Colombia, Bogotá, Colombia.

New Findings: What is the central question of this study? To what extent does testosterone influence hemoglobin formation during male puberty? What is the main finding and its importance? In boys, testosterone might be responsible for about 65% of the increase in hemoglobin mass during puberty. The underlying mechanisms are assumed to be twofold: (i) indirectly, mediated by the increase in LBM, and (ii) directly by immediate testosterone effects on erythropoiesis. Thereby, an increase in testosterone by 1ng/ml is associated with an increase in Hbmass by ∼65g. Read More

Ultrathin Three-Monolayer Tunneling Memory Selectors.

ACS Nano 2021 May 4. Epub 2021 May 4.

Department of Electrical Engineering, Stanford University, Stanford, California 94305, United States.

High-density memory arrays require selector devices, which enable selection of a specific memory cell within a memory array by suppressing leakage current through unselected cells. Such selector devices must have highly nonlinear current-voltage characteristics and excellent endurance; thus selectors based on a tunneling mechanism present advantages over those based on the physical motion of atoms or ions. Here, we use two-dimensional (2D) materials to build an ultrathin (three-monolayer-thick) tunneling-based memory selector. Read More

Effects of moderate intensity endurance training and high-intensity interval training on the reproductive parameters of wistar rats overfed in infancy.

Chin J Physiol 2021 Mar-Apr;64(2):106-114

Department of Medicine, Postgraduate Health Program, Federal University of Juiz de Fora, Juiz de Fora, MG, Brazil.

Studies indicate that rapid weight gain at critical development stages, such as the lactation period, is associated with the development of obesity, cardiovascular diseases, and diabetes in the long term. In addition to metabolic changes during adulthood, overweight/obesity may influence reproductive function. Human and animal studies suggest that lifestyle changes through exercise and/or controlled diet result in improved semen quality in obese individuals. Read More

Training response to 8 weeks of blood flow restricted training is not improved by preferentially altering tissue hypoxia or lactate accumulation when training to repetition failure.

Appl Physiol Nutr Metab 2021 Apr 30. Epub 2021 Apr 30.

University of Guelph, 3653, Human Health and Nutritional Sciences, Guelph, Canada;

Despite compelling muscular structure and function changes resulting from blood flow restricted (BFR) resistance training, mechanisms of action remain poorly characterized. Alterations in tissue O2 saturation (TSI%) and metabolites are potential drivers of observed changes, but their relationships with degree of occlusion pressure are unclear. We examined local TSI% and blood lactate (BL) concentration during BFR training to failure using different occlusion pressures on strength, hypertrophy, and muscular endurance over an 8-week training period.

Department of Materials Science and Engineering, Ulsan National Institute of Science and Technology (UNIST), Ulsan, 44919, Republic of Korea.

Compared with the large plastic deformation observed in ductile metals and organic materials, inorganic semiconductors have limited plasticity (<0.2%) due to their intrinsic bonding characters, restricting their widespread applications in stretchable electronics. Herein, the solution-processed synthesis of ductile α-Ag S thin films and fabrication of all-inorganic, self-powered, and stretchable memory devices, is reported. Read More

Endurance exercise and the risk of cardiovascular pathology in men: a comparison between lifelong and late-onset endurance training and a non-athletic lifestyle - rationale and design of the Master@Heart study, a prospective cohort trial.

BMJ Open Sport Exerc Med 2021 16;7(2):e001048. Epub 2021 Apr 16.

Cardiovascular Sciences, KU Leuven University Hospitals Leuven, Leuven, Flanders, Belgium.

Introduction: Low and moderate endurance exercise is associated with better control of cardiovascular risk factors, a decreased risk of coronary artery disease and atrial fibrillation (AF). There is, however, a growing proportion of individuals regularly performing strenuous and prolonged endurance exercise in which the health benefits have been challenged. Higher doses of endurance exercise have been associated with a greater coronary atherosclerotic plaque burden, risk of AF and myocardial fibrosis (MF). Read More
