AbstractObjectives Mental fatigue impairs endurance exercise. Brain training (BET) – engaging in cognitively fatiguing tasks during exercise - can develop resilience to mental and improve physical performance over alone. The mechanism for this effect is unknown. This experiment examines if BET enhances investigates potential underlying physiological mechanisms. Design...
The present study was designed to determine if gender affects the adaptive response to endurance exercise training of left ventricular filling dynamics in older individuals. Recently, it was shown that gender influences the cardiovascular responses to endurance exercise training in older subjects. Older men improve left ventricular systolic performance and increase maximal cardiac output in res...
OBJECTIVES The objective of the study was to investigate the impact of alteration of glycogen stores and metabolism on exercise performance in patients with heart failure. BACKGROUND In normal subjects, muscle glycogen depletion results in increased exertional fatigue and reduced endurance. Skeletal muscle biopsies have revealed reduced glycogen content in patients with congestive heart failu...
background: the purpose of the present study was to examine whether a first bout of exhaustive exercise can change inflammo-endocrine responses to second subsequent similar exercise on the same day. cortisol, tnf-α, and adenosin deaminas enzyme (ada) were assessed during a progressive endurance protocol. methods: eight well trained endurance runners (aged 23.13±3.39 years; weight, 66.21±9.47 ...
Endurance performance involves the prolonged maintenance of constant or self-regulated power/velocity or torque/force. While the impact of numerous determinants of endurance performance has been previously reviewed, the impact of fatigue on subsequent endurance performance still needs to be documented. This review aims to present the impact of fatigue induced by physical or mental exertion on s...
introduction: this research was aimed at examining acute responses of hormones such as growth hormone (gh), total testosterone (tt), free testosterone (ft), free fatty acid (ffa) and cortisol to resistance (r), endurance (e) and endurance-resistance (er) exercise. methods: the participants of this study were 10 healthy young men. r protocol included bench press, lateral pull down, leg extension...
Background: The herpes simplex viruses cause a variety of clinical illnesses that are painful and often distressing. To control the infection, the development of an effective vaccine that prevents or reduces the primary and recurrent infections would be of great significance. With considering to immunological changes following an acute endurance exercise, the purpose of this study was to assess...
INTRODUCTION This randomized, controlled study on patients with polymyositis or dermatomyositis was based on three hypotheses: patients display impaired endurance due to reduced aerobic capacity and muscle weakness, endurance training improves their exercise performance by increasing the aerobic capacity, and endurance training has general beneficial effects on their health status. METHODS In...
Slow component of oxygen uptake (VO2SC) kinetics and maximal oxygen uptake (VO2max) attainment seem to influence endurance performance during constant-work rate exercise (CWR) performed within the severe intensity domain. In this study, it was hypothesized that delaying the attainment of VO2max by reducing the rates at which VO2 increases with time (VO2SC kinetics) would improve the endurance p...
High-intensity interval training (HIIT) is a time-efficient way of improving physical performance in healthy subjects and in patients with common chronic diseases, but less so in elite endurance athletes. The mechanisms underlying the effectiveness of HIIT are uncertain. Here, recreationally active human subjects performed highly demanding HIIT consisting of 30-s bouts of all-out cycling with 4...
