How Common Is the Exponential Decay Pattern of Motor Skill Acquisition? A Brief Investigation.

Motor Control 2021 May 13:1-11. Epub 2021 May 13.

University of Utah.

Motor performance is classically described as improving nonlinearly with practice, demonstrating rapid improvements early in practice with stabilization later, which is commonly modeled by exponential decay functions. However, retrospective analyses of our previously collected data challenge this theoretical model of motor skill acquisition, suggesting that a majority of individual learners actually demonstrate patterns of motor improvement different from this classical model. A convenience sample of young adults, older adults, and people with Parkinson disease trained on the same functional upper-extremity task. Read More

The effect of lower airway inflammation on inflammatory cytokine gene expression in bronchoalveolar lavage fluid and whole blood in racing Thoroughbreds.

Vet Immunol Immunopathol 2021 May 9;237:110266. Epub 2021 May 9.

Department of Veterinary Clinical Sciences, College of Veterinary Medicine, Purdue University, West Lafayette, IN, USA.

Background: Immunological mechanisms involved in the pathogenesis of mild to moderate equine asthma (MEA) are not completely understood. There are limited data on bronchoalveolar lavage fluid (BALF) and blood inflammatory cytokine profiles in racehorses with MEA, and the effect of racing on inflammatory cytokines is unknown.

Hypothesis/objectives: We hypothesized that inflammatory cytokine gene expression in BALF and resting blood would be higher in racehorses with lower airway inflammation compared to healthy controls, and that gene expression in blood collected immediately post-race would be increased compared to resting blood in racehorses with lower airway inflammation.

Caffeine increases myoglobin expression via the cyclic AMP pathway in L6 myotubes.

Physiol Rep 2021 May;9(9):e14869

Faculty of Sport and Health Science, Ritsumeikan University, Shiga, Japan.

Myoglobin is an important regulator of muscle and whole-body metabolism and exercise capacity. Caffeine, an activator of the calcium and cyclic AMP (cAMP)/protein kinase A (PKA) pathway, enhances glucose uptake, fat oxidation, and mitochondrial biogenesis in skeletal muscle cells. However, no study has shown that caffeine increases the endogenous expression of myoglobin in muscle cells. Read More

Prevention of non-alcoholic steatohepatitis by long-term exercise via the induction of phenotypic changes in Kupffer cells of hyperphagic obese mice.

Physiol Rep 2021 May;9(9):e14859

Faculty of Medicine, University of Tsukuba, Tsukuba-shi, Ibaraki, Japan.

Exercise ameliorates nonalcoholic fatty liver disease (NAFLD) by inducing phenotypic changes in Kupffer cells (KCs). p62/Sqstm1-knockout (p62-KO) mice develop NAFLD alongside hyperphagia-induced obesity. We evaluated (1) the effects of long-term exercise on the foreign-body phagocytic capacity of KCs, their surface marker expression, and the production of steroid hormones in p62-KO mice; and (2) whether long-term exercise prevented the development of non-alcoholic steatohepatitis (NASH) in p62-KO mice fed a high-fat diet (HFD).

The effect of repeated bouts of electrical stimulation-induced muscle contractions on proteolytic signaling in rat skeletal muscle.

Physiol Rep 2021 May;9(9):e14842

Department of Life Sciences, Graduate School of Arts and Sciences, The University of Tokyo, Tokyo, Japan.

Mechanistic target of rapamycin complex 1 (mTORC1) plays a central role in muscle protein synthesis and repeated bouts of resistance exercise (RE) blunt mTORC1 activation. However, the changes in the proteolytic signaling when recurrent RE bouts attenuate mTORC1 activation are unclear. Using a RE model of electrically stimulated rat skeletal muscle, this study aimed to clarify the effect of repeated RE bouts on acute proteolytic signaling, particularly the calpain, autophagy-lysosome, and ubiquitin-proteasome pathway.

Demand creates its own supply: the Na/K-ATPase controls metabolic reserve and flexibility.

Acta Physiol (Oxf) 2021 May 15:e13673. Epub 2021 May 15.

Department of Biomedicine, Aarhus University, Denmark.

The study by Kurtz et al. validated the hypothesis that the Na/K-ATPase controls metabolic capacity via Src kinase signalling. They found that regulatory attenuation of Src kinase signalling by the Na/K-ATPase α1 isoform correlates with improved metabolic reserve and substrate flexibility that increase exercise endurance.

Postprandial amino acid availability after intake of intact or hydrolyzed meat protein in a mixed meal in healthy elderly subjects: a randomized, single blind crossover trial.

Amino Acids 2021 May 15. Epub 2021 May 15.

Institute of Sports Medicine Copenhagen, Department of Orthopedic Surgery, Copenhagen University Hospital-Bispebjerg and Frederiksberg, Nielsine Nielsensvej 11, Building 8, 1st floor, 2400, Copenhagen, NV, Denmark.

The absorption of dietary proteins affects the anabolic response, among others protein synthesis. For elderly, optimal amino acid absorption is warranted to preserve the amino acid pool of the body, especially skeletal muscle proteins. Therefore, the aim of this study was to characterize if hydrolyzing meat protein (HMP) would improve the amino acid absorption after ingestion of meat compared to equal amounts of the same meat proteins but present in a different structure; steak or minced meat.

Multimodality assessment of heart failure with preserved ejection fraction skeletal muscle reveals differences in the machinery of energy fuel metabolism.

ESC Heart Fail 2021 May 15. Epub 2021 May 15.

Penn Cardiovascular Institute, Division of Cardiovascular Medicine, Hospital of the University of Pennsylvania, Philadelphia, PA, 19104, USA.

Aims: Skeletal muscle (SkM) abnormalities may impact exercise capacity in patients with heart failure with preserved ejection fraction (HFpEF).

Shining a light on ideas worth researching in the field of eating disorders: Introduction to a Virtual Issue of the International Journal of Eating Disorders.

Int J Eat Disord 2021 May 14. Epub 2021 May 14.

Department of Psychology, Wesleyan University, Middletown, Connecticut, USA.

In celebration of the 2021 International Conference on Eating Disorders, this Virtual Issue showcases Spotlight articles published since 2019 in the International Journal of Eating Disorders. Spotlight articles identify gaps in the literature and propose novel "ideas worth researching" to improve understanding, etiology, epidemiology, impacts, and prevention or treatment of eating disorders. Nine such articles are presented and are grouped thematically into: exploring mechanisms underlying distinct eating disorder symptoms (severe food restriction; driven exercise; sleep disturbance); comparing cost-effectiveness of two commonly employed treatment formats (intensive day treatment vs. Read More

Relationship of end-tidal oxygen partial pressure to the determinants of anaerobic threshold in post-myocardial infarction patients.

Heart Vessels 2021 May 14. Epub 2021 May 14.

Department of Cardiology, Sanda City Hospital, Sanda, Japan.

The anaerobic threshold (AT), obtained during cardiopulmonary exercise testing (CPET), is an important prognostic measure and can be used to develop an exercise prescription in patients after a myocardial infarction (post-MI). The purpose of this study was to examine the central and peripheral determinants of AT in post-MI patients end-tidal oxygen partial pressure (PETO) measures. We performed cardiopulmonary exercise testing (CPET) on 148 consecutively enrolled post-MI patients to determine PETO measured at the AT (AT PETO) and ΔPETO (difference between resting PETO and AT PETO).
