Widened QRS-T Angle May Be a Measure of Poor Ventricular Stretch During Exercise Among On-duty Firefighters.

J Cardiovasc Nurs 2018 Dec 5. Epub 2018 Dec 5.

Dillon J. Dzikowicz, BS, RN Doctoral (PhD) Student, School of Nursing, University of Rochester, New York. Mary G. Carey, PhD, RN, FAHA, FAAN Associate Professor, School of Nursing, University of Rochester, New York.

Background: The spatial QRS-T angle is a measure of repolarization heterogeneity and may be a predictor of poor ventricular health. It is unknown whether a relationship exists between QRS-T angle and blood pressure (BP) during exercise.

Objective: The purpose of this study was to evaluate the potential relationship between QRS-T angle and BP during exercise, which may be indicative of ventricular stretch. Read More

Cardiometabolic and Muscular Fatigue Responses to Different CrossFit® Workouts.

J Sports Sci Med 2018 Dec 20;17(4):668-679. Epub 2018 Nov 20.

TecnoCampus, Pompeu Fabra University, Barcelona, Spain.

CrossFit® consists of workouts of the day (WODs) in which different exercises are conducted at high intensity with minimal or no rest periods. This study sought to quantify exercise intensity and muscular fatigue in the three CrossFit® session modalities: gymnastics (G), metabolic conditioning (M) and weightlifting (W). Thirty two, young, strength-trained, healthy men completed the three WODs: G ("Cindy"), M (double skip rope jumps) and W (power cleans). Read More

Mem. ASME Professor Mechanical Engineering, 325 Leonhard Building, Penn State University, University Park, PA 16802 e-mail: .

This paper aims to develop a data-driven model for glucose dynamics taking into account the effects of physical activity (PA) through a numerical study. It intends to investigate PA's immediate effect on insulin-independent glucose variation and PA's prolonged effect on insulin sensitivity. We proposed a nonlinear model with PA (NLPA), consisting of a linear regression of PA and a bilinear regression of insulin and PA. Read More

Postexercise hypotension as a clinical tool: a "single brick" in the wall.

J Am Soc Hypertens 2018 Oct 24. Epub 2018 Oct 24.

Exercise Hemodynamic Laboratory, School of Physical Education and Sport, University of São Paulo, São Paulo, Brazil.

After an exercise session, a reduction of blood pressure (BP) is expected, a phenomenon called postexercise hypotension (PEH). PEH as a predictor of chronic training responses for BP has been broadly explored. It suggests that when PEH occurs after each exercise sessions, its benefits may summate over time, contributing to the chronic adaptation. Read More

Department of Cardiology, Queen Elizabeth Hospital, Birmingham, United Kingdom.

Background: Patients with adult congenital heart disease (ACHD) have an increased risk of arrhythmic and sudden cardiac death. The subcutaneous implantable cardioverter defibrillator (S-ICD) provides a potentially safer alternative to transvenous ICDs in ACHD. Suitability for S-ICD depends on the surface electrocardiogram (ECG), which is often abnormal in ACHD patients. Read More

Acute reduction in posterior cerebral blood flow following isometric handgrip exercise is augmented by lower body negative pressure.

Department of Biomedical Engineering, Toyo University, Kawagoe-shi, Saitama, Japan.

The mechanism(s) for the increased occurrence of a grayout or blackout, syncope, immediately after heavy resistance exercise are unclear. It is well-known that orthostatic stress increases the occurrence of postexercise syncope. In addition, previous findings have suggested that hypo-perfusion, especially in the posterior cerebral circulation rather than anterior cerebral circulation, may be associated with the occurrence of syncope.

Purpose: Few studies have directly compared excess postexercise oxygen consumption (EPOC) and fat utilization following different exercise intensities, and the effect of continuous exercise exceeding 75% of maximal oxygen uptake (VOmax) on these parameters remains unexplored. The current study examined EPOC and fat utilization following acute moderate- and vigorous-intensity continuous training (MICT and VICT) and sprint interval training (SIT).

Methods: Eight active young men performed 4 experimental sessions: (a) MICT (30 min of running at 65% VOmax); (b) VICT (30 min of running at 85% VOmax); (c) SIT (4 30-s "all-out" sprints with 4 min of rest); and (d) no exercise (REST). Read More

Whole egg, but not egg white, ingestion induces mTOR colocalization with the lysosome after resistance exercise.

Am J Physiol Cell Physiol 2018 Oct 22;315(4):C537-C543. Epub 2018 Aug 22.

Faculty of Kinesiology and Physical Education, University of Toronto , Toronto, Ontario , Canada.

We have recently demonstrated that whole egg ingestion induces a greater muscle protein synthetic (MPS) response when compared with isonitrogenous egg white ingestion after resistance exercise in young men. Our aim was to determine whether whole egg or egg white ingestion differentially influenced colocalization of key regulators of mechanistic target of rapamycin complex 1 (mTORC1) as means to explain our previously observed divergent postexercise MPS response. In crossover trials, 10 healthy resistance-trained men (21 ± 1 yr; 88 ± 3 kg; body fat: 16 ± 1%; means ± SE) completed lower body resistance exercise before ingesting whole eggs (18 g protein, 17 g fat) or egg whites (18 g protein, 0 g fat).

Postexercise improvement in glucose uptake occurs concomitant with greater γ3-AMPK activation and AS160 phosphorylation in rat skeletal muscle.

Am J Physiol Endocrinol Metab 2018 Aug 21. Epub 2018 Aug 21.

School of Kinesiology, University of Michigan, United States.

A single exercise session can increase insulin-stimulated glucose uptake (GU) by skeletal muscle concomitant with greater Akt substrate of 160 kDa (AS160) phosphorylation on Akt-phosphosites (Thr and Ser) that regulate insulin-stimulated GU. Recent research using mouse skeletal muscle suggested that ex vivo AICAR or electrically stimulated contractile activity inducing increased γ3-AMPK activity and AS160 phosphorylation on a consensus AMPK-motif (Ser) resulted in greater AS160 Thr phosphorylation and GU by insulin-stimulated muscle. Our primary goal was to determine if in vivo exercise that increases insulin-stimulated GU in rat skeletal muscle would also increase γ3-AMPK activity and AS160 site-selective phosphorylation (Ser, Thr and Ser) immediately post-exercise (IPEX) and/or 3 hours post-exercise (3hPEX).

Background: Prolonged endurance running may acutely reduce spirometric lung values. This study examined changes in spirometry before and immediately after prolonged endurance exercise (running and/or walking). Specifically, we examined potential factors that predict the presence of at least a 10% postexercise reduction in FEV. Read More

In Vivo Assessment of Exercise-Induced Glenohumeral Cartilage Strain.

Orthop J Sports Med 2018 Jul 13;6(7):2325967118784518. Epub 2018 Jul 13.

Department of Orthopaedic Surgery, James R. Urbaniak, MD, Sports Sciences Institute, Duke University, Durham, North Carolina, USA.

Background: The human shoulder joint is the most mobile joint in the body. While in vivo shoulder kinematics under minimally loaded conditions have been studied, it is unclear how glenohumeral cartilage responds to high-demand loaded exercise.

Hypothesis: A high-demand upper extremity exercise, push-ups, will induce compressive strain in the glenohumeral articular cartilage, which can be measured with validated magnetic resonance imaging (MRI)-based techniques. Read More

Single Bout Exercise in Children with Juvenile Idiopathic Arthritis: Impact on Inflammatory Markers.

Mediators Inflamm 2018 13;2018:9365745. Epub 2018 Jun 13.

Pédiatrie Générale Multidisciplinaire, Hôpital Estaing, CHU Clermont-Ferrand, 63000 Clermont-Ferrand, France.

Objective: In a context of inflammatory disease such as juvenile idiopathic arthritis (JIA), we do not know what impact physical activity may have on a deregulated immune system. The objective is to measure the impact of a single bout of exercise on plasma inflammatory markers such as calprotectin, IL-6, sIL-6R, sgp130, and the hypothalamic-pituitary-adrenal axis in children with juvenile idiopathic arthritis.

Methods: Twelve children with JIA performed a nonexercise control day and a consecutive day that included a 20 min exercise bout at 70% of max-HR at 08:30 am. Read More
