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

The purpose was to examine the acute skeletal muscle response to high load exercise and low-load exercise with and without different levels of applied pressure (BFR). A total of 22 participants completed the following four conditions: elbow flexion exercise to failure using a traditional high load [70% 1RM, (7000)], low load [15% 1RM,(1500)], low load with moderate BFR [15%1RM+40%BFR(1540)] or low load with greater BFR [15% 1RM+80%BFR(1580)]. Torque and muscle thickness were measured prior to, immediately post, and 15 min postexercise. Read More

Excess postexercise oxygen consumption (EPOC) is an elevation in oxygen consumption (Vo₂) following exercise. Altitude decreases maximal oxygen uptake; however, studies are equivocal concerning the effect on resting metabolic rate. The EPOC response has not been studied with normobaric hypoxia. Read More

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

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

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

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

Structured exercise programs initiated after acute hospitalization can improve muscle strength and mass, cardiorespiratory capacity, and quality of life in severely burned children. In this retrospective study, we compared the cardiovascular effects of an exercise program incorporating a large number of interval training sessions with a traditional exercise program incorporating a small number of interval training sessions. Severely burned children who completed a large number of sessions (≥3 sessions per week, N=40) were matched to those completing a small number of sessions (≤2 sessions per week, N=40). Read More

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).

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).
