Acute moderate hypoxic exposure can substantially impair exercise performance, which occurs with a concurrent exacerbated rise in hydrogen cation (H+) production. The purpose of this study was therefore, to alleviate this acidic stress through sodium bicarbonate (NaHCO3) supplementation and determine the corresponding effects on severe-intensity intermittent exercise performance. Eleven recreationally active individuals participated in this randomised, double-blind, crossover study performed under acute normobaric hypoxic conditions (FiO2% = 14...

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...

Recent decades have seen a rapid increase in reported toxic effects of drugs and pollutants on mitochondria. Researchers have also documented many genetic differences leading to mitochondrial diseases, currently reported to affect ∼1 person in 4,300, creating a large number of potential gene-environment interactions in mitochondrial toxicity. We briefly review this history, and then highlight cutting-edge areas of mitochondrial research including the role of mitochondrial reactive oxygen species in signaling; increased understanding of fundamental biological processes involved in mitochondrial homeostasis (DNA maintenance and mutagenesis, mitochondrial stress response pathways, fusion and fission, autophagy and biogenesis, and exocytosis); systemic effects resulting from mitochondrial stresses in specific cell types; mitochondrial involvement in immune function; the growing evidence of long-term effects of mitochondrial toxicity; mitochondrial-epigenetic cross-talk; and newer approaches to test chemicals for mitochondrial toxicity...

Authors have proposed a concept of guidelines for applying the ambulatory complex cardiovascular rehabilitation (ACCVR) into the clinical practice in Slovakia. As a background they have used an actual cardiovascular mortality and morbidity data from home country and abroad as well. They emphasize the non-optimal situation in this aspect which may not be solved by the increasing supporting the invasive revascularization methods and by the intensifying pharmacotherapy only, because the favourable effects of these procedures is timely missing if it is not accompanied by the therapeutic lifestyle changes...
