Building on previous work indicating that mood instability is the hallmark of neuroticism, our aim was to examine whether changes in exercise, sleep duration, and leisure predicted decreases in mood instability with time. We used data from 3,374 participants of the British Health and Lifestyle Study who answered the Eysenck ...

BACKGROUND: Targeted mutation site-specific differences have correlated C-loop missense mutations with worse outcomes and increased benefit of beta-blockers in LQT1. This observation has implicated the C-loop region as being mechanistically important in the altered response to sympathetic stimulation known to put patients with LQT1 at risk of syncope and sudden ...

Mitochondrial myopathies commonly present with exercise intolerance typified by breathlessness and fatigue on exercise. In contrast, exercise-induced rhabdomyolysis and myoglobinuria occur rarely. We present a 43-year-old man with a lifelong history of exercise intolerance associated with myalgia and recurrent episodes of exercise-induced myoglobinuria. From early childhood, he had weekly episodes ...

Objectives: The prevalence of chronic heart failure and a reduced ejection fraction (CHF-REF) has increased over the last decade. The cardiopulmonary exercise test (CPET) is an established tool for managing these patients. For patients who are administered beta-blockers, its predictive value is debated. The aim of this study was to ...

Fat and carbohydrate are the primary fuel sources for mitochondrial ATP production in human skeletal muscle during endurance exercise. However, fat exhibits a relatively low maximal rate of oxidation in vivo, which begins to decline at around 65% of maximal oxygen consumption (VO2max) when muscle glycogen becomes the major fuel. ...

BACKGROUND: Any increase in heart rate (HR) during daily activities above the ischemic threshold may trigger myocardial ischemia. HR reduction with the I(f) inhibitor ivabradine has been demonstrated to confer anti-ischemic and antianginal efficacy in patients with stable angina pectoris. This analysis of the ASSOCIATE trial assessed whether the anti-ischemic ...

L-Carnitine is a conditionally essential nutrient and plays an important role in mitochondrial β-oxidation. As a dietary supplement for athletes, L-carnitine has been investigated for its potential to enhance β-oxidation during exercise ultimately to improve performance. While some studies have shown a positive impact on VO(2 max) and other performance ...

To both prevent and accelerate recovery and return-to-play from ankle sprains, clinicians frequently employ the use of external prophylactic support (EPS), such as taping and bracing, to provide mechanical support to the ankle joint. While common practice clinically, research has been inconclusive in demonstrating the effectiveness of EPS in restricting ...

Prevailing physiological paradigms explain both sprint and endurance exercise performance in terms of the availability of metabolic energy. However, for all-out efforts of 60 s or less, the prevailing view is no longer viable. Contemporary evidence indicates that sprinting performance is determined by musculoskeletal force application, with a duration dependency ...

The definition of proprioception in the literature is equivocal, therefore it is desirable for communication and comprehension purposes that all authors who use proprioception and its related terms reach a consensus as to their meaning. This review aims to clarify these terms and to improve the understanding of the proprioceptive ...

Standardized graded exercise test (GXT) protocols are ineffective for testing endurance athletes. Scientists have called for the abandonment of traditional techniques for corroborating "true" maximum oxygen uptake (VO2max), as measured during a GXT. Instead, a new technique, the verification bout subsequent to the GXT, has emerged for establishing the "true" ...

We have found in four sheep that, following a muscular exercise, minute ventilation is maintained for 34-131 s during a cardiac arrest (CA), at a magnitude (from 28.2 and 54.7 l min(-1)) similar to the level of ventilation (and thus proportional to the metabolic rate) preceding the period of asystole. ...

Abstract Three modern views about the factors limiting oxygen uptake in healthy humans are set against the original (early 1920s) concept of A. V. Hill and colleagues. The majority view for most of the intervening time has been that cardiac output is the essential limiting function. Among recent research in ...

Coherence between electroencephalography (EEG) recorded on the scalp above the motor cortex and electromyography (EMG) recorded on the skin of the limbs is thought to reflect corticospinal coupling between motor cortex and muscle motor units. Beta-range (13-30 Hz) corticomuscular coherence has been extensively documented during static force output while gamma-range ...

Optimization of atrioventricular delay (AVD) and interventricular delay (VVD) in patients with a biventricular (Biv) pacemaker has been associated with improvement in cardiac output acutely, a reduction in heart failure symptoms, and improved exercise capacity. Several individual echocardiography (echo) Doppler parameters have been used for pacemaker optimization. In this review, ...

Should We Optimize CRT During Exercise? Cardiac resynchronization therapy aims at diminishing cardiac dyssynchrony in patients with heart failure. The effect of cardiac resynchronization therapy can be improved by optimization of the atrioventricular (AV) and interventricular (VV) delays. Currently, optimization of these pacing settings is mainly performed during resting conditions. ...

A 53-year-old man with previous aortic valve surgery presented with paroxysmal narrow complex tachycardia, induced by exercise. His PR interval was greater than 400 ms when in sinus rhythm and atrioventricular nodal reentry tachycardia (AVNRT) was diagnosed with invasive electrophysiological studies. Single echoes were repeatedly inducible with single-paced extrastimuli. Cryotherapy ...

The identification of affected family members with long QT syndrome (LQTS) is often difficult due to their normal-or only marginally lengthened-QT interval duration. We examined whether physical exercise test could increase the ability to detect the mutation carrier status in phenotypically normal LQTS family members. Sixty-six subjects were included: 15 ...
