Respir Physiol Neurobiol 2021 Jun 9:103714. Epub 2021 Jun 9.

International Collaboration on Repair Discoveries, Vancouver, BC, V5Z 1M9, Canada; Canadian Sport Institute - Pacific, Victoria, BC, V9E 2C5, Canada; Faculty of Medicine, University of British Columbia, Kelowna, BC, V1Y 1T3, Canada. Electronic address:

We compared cardiopulmonary responses to arm-ergometry, in individuals with cervical spinal cord injury (C-SCI) and able-bodied controls. We hypothesized that individuals with C-SCI would have higher respiratory frequency (f) but lower tidal volume (VT) at a given work rate and dynamically hyperinflate during exercise, whereas able-bodied individuals would not. Participants completed pulmonary function testing, an arm-ergometry test to exhaustion, and a sub-maximal exercise test consisting of four-minute stages at 20, 40, 60, and 80% peak work rate.

Loss of the transcriptional repressor Rev-erbα upregulates metabolism and proliferation in cultured mouse embryonic fibroblasts.

Sci Rep 2021 Jun 11;11(1):12356. Epub 2021 Jun 11.

Department of Molecular Biology, Cellular Biology, and Biochemistry, Brown University, 185 Meeting Street, Providence, RI, 02912, USA.

The transcriptional repressor Rev-erbα is known to down-regulate fatty acid metabolism and gluconeogenesis gene expression. In animal models, disruption of Rev-erbα results in global changes in exercise performance, oxidative capacity, and blood glucose levels. However, the complete extent to which Rev-erbα-mediated transcriptional repression of metabolism impacts cell function remains unknown. Read More

Prediction of underwater residual lung volume in healthy men and women.

Clin Physiol Funct Imaging 2021 Jun 11. Epub 2021 Jun 11.

Department of Kinesiology, University of Alabama, Tuscaloosa, AL, USA.

Regression equations are commonly used to predict residual lung volume (RV) during underwater weighing when measurement is not practical. However, the equations currently available were derived from on-land measures of RV and may account for changes in lung capacity during submersion, thus leading to inaccuracies in assessment of percent body fat (%BF). The purpose of this study was to 1) develop a new equation (RV ) for the prediction of underwater RV, 2) cross-validate RV and compare it to existing RV equations, and 3) compare the effects of RV and existing equations on underwater %BF.

Web-Based Self-management Program (SPACE for COPD) for Individuals Hospitalized With an Acute Exacerbation of Chronic Obstructive Pulmonary Disease: Nonrandomized Feasibility Trial of Acceptability.

JMIR Mhealth Uhealth 2021 Jun 11;9(6):e21728. Epub 2021 Jun 11.

Centre for Exercise and Rehabilitation Science, University Hospitals of Leicester NHS Trust, Leicester, United Kingdom.

Background: Hospital admissions due to the acute exacerbation of chronic obstructive pulmonary disease (AECOPD) are costly for individuals and health services. Pulmonary rehabilitation (PR) is known to reduce hospital readmissions when delivered after hospitalization, but the uptake and completion of PR following hospitalization remains poor (<10% of those eligible in the UK audit data). A web-based platform of the SPACE (Self-management Program of Activity Coping and Education) for COPD (chronic obstructive pulmonary disease) has previously shown promising results in patients with stable COPD but has not been tested following an AECOPD.

Deciphering the constrained total energy expenditure model in humans by associating accelerometer-measured physical activity from wrist and hip.

Sci Rep 2021 Jun 10;11(1):12302. Epub 2021 Jun 10.

PROFITH "PROmoting FITness and Health Through Physical Activity" Research Group, Sport and Health University Research Institute (iMUDS), Department of Physical and Sports Education, Faculty of Sport Sciences, University of Granada, Crta Alfcar s/n, 18011, Granada, Spain.

The constrained total energy expenditure (TEE) model posits that progressive increases in physical activity (PA) lead to increases in TEE; but after certain PA threshold, TEE plateaus. Then, a compensatory reduction in the expenditure of non-essential activities constrains the TEE. We hypothesized that high PA levels as locomotion associate with a compensatory attenuation in arm movements. Read More

Heart and Vascular Center, Dartmouth-Hitchcock Medical Center, Geisel School of Medicine at Dartmouth, Lebanon, NH (M.A.C.).

Peripheral artery disease (PAD) is a manifestation of systemic atherosclerosis. Modifiable risk factors including cigarette smoking, dyslipidemia, diabetes, poor diet quality, obesity, and physical inactivity, along with underlying genetic factors contribute to lower extremity atherosclerosis. Patients with PAD often have coexistent coronary or cerebrovascular disease, and increased likelihood of major adverse cardiovascular events, including myocardial infarction, stroke and cardiovascular death.

Astaxanthin supplementation enhances metabolic adaptation with aerobic training in the elderly.

Physiol Rep 2021 Jun;9(11):e14887

Department of Radiology, University of Washington, Seattle, WA, USA.

Endurance training (ET) is recommended for the elderly to improve metabolic health and aerobic capacity. However, ET-induced adaptations may be suboptimal due to oxidative stress and exaggerated inflammatory response to ET. The natural antioxidant and anti-inflammatory dietary supplement astaxanthin (AX) has been found to increase endurance performance among young athletes, but limited investigations have focused on the elderly.

Effect of portable non-invasive ventilation on thoracoabdominal volumes in recovery from intermittent exercise in patients with COPD.

J Appl Physiol (1985) 2021 06 10. Epub 2021 Jun 10.

Department of Sport, Exercise and Rehabilitation, Northumbria University, Newcastle Upon-Tyne, United Kingdom.

Background: We previously showed that use of portable non-invasive ventilation (pNIV) during recovery periods within intermittent exercise improved breathlessness and exercise tolerance in COPD patients compared to pursed-lip breathing (PLB). However, in a minority of patients recovery from dynamic hyperinflation (DH) was better with PLB, based on inspiratory capacity. We further explored this using Optoelectronic Plethysmography to assess total and compartmental thoracoabdominal volumes. Read More

A split-label design for simultaneous measurements of perfusion in distant slices by pulsed arterial spin labeling.

Magn Reson Med 2021 Jun 9. Epub 2021 Jun 9.

C.J. Gorter Center for High Field MRI, Department of Radiology, Leiden University Medical Center, Leiden, the Netherlands.

Purpose: Multislice arterial spin labeling (ASL) MRI acquisitions are currently challenging in skeletal muscle because of long transit times, translating into low-perfusion SNR in distal slices when large spatial coverage is required. However, fiber type and oxidative capacity vary along the length of healthy muscles, calling for multislice acquisitions in clinical studies. We propose a new variant of flow alternating inversion recovery (FAIR) that generates sufficient ASL signal to monitor exercise-induced perfusion changes in muscle in two distant slices. Read More

High Incidence of Bronchospastic Response to a Stair Climbing Exercise.

Cureus 2021 May 4;13(5):e14843. Epub 2021 May 4.

Institute of Sport Science and Innovations, Lithuanian Sports University, Kaunas, LTU.

Background While it is increasingly recognized that exercise-induced bronchoconstriction (EIB) affects a substantial proportion of sport participants, the relation of EIB incidence and severity to the type and intensity of exertion remains under-investigated. The aim of this study was to establish the incidence and severity of EIB during a stair race, a highly demanding all-out effort exercise. We hypothesized that a large proportion of participants would develop EIB to this particular high-intensity competition, and that among the predisposing factors, severity of EIB would depend on the level of exertion.
