OBJECTIVE To determine if there is an association between supine leg-length alignment (LLA) asymmetry and the endurance of the erector spinae (ES) and quadratus lumborum (QL) muscles. METHODS Forty-seven subjects (21 women; average age, 36 years old) were tested for ES endurance using the Biering-Sorensen (B-S) test, and 69 (31 women; average age, 34.5 years) were tested for QL endurance. Sub...

the aim of this study was to investigate the effect of endurance, resistance and concurrent training on plasma leptin levels of male students. for this purpose, 48 male university students (mean age 21.45 years) participated in this study. subjects were randomly assigned to three exercise groups: endurance group (n=12), resistance group (n=12) and concurrent group (n=12) and a control group (n=...

background: the purpose of the present study was to investigate the effect of endurance training on amount of nicotinic acetylcholine receptors (nachr) in fast and slow twitch muscles of male wistar rats. methods: a number of 15 male wistar rats randomly divided into two groups of control (n=7) and endurance training (n=8). the endurance training treadmill running (for 12 consecutive week, 5 da...

Altered autonomic function has been identified following ultra-endurance event participation among elite world-class athletes. Despite dramatic increases in recreational athlete participation in these ultra-endurance events, the physiological effects on these athletes are less known. This investigation sought to characterise changes in surrogate measures of autonomic function: heart rate variab...

The regulation of endurance training is usually based on the prescription of exercise intensity. Exercise duration, another important variable of training load, is rarely prescribed by individual measures and mostly set from experience. As the specific exercise duration for any intensity plays a substantial role regarding the different kind of cellular stressors, degree, and kind of fatigue as ...

[Purpose] The purpose of this study was to investigate the effects of 8 weeks of endurance exercise on the cardiac mitochondrial function of mice. [Subjects] Ten 129 SvJ/C57BL6 Male mice were used. The mice were randomly divided into an exercise group (n=5; mean ± SD weight, 27.4 ± 1.6 g) and a control (n=5; mean ± SD weight, 28.2 ± 1.1 g). The exercise mice ran on a motor driven treadmill 5 da...

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...

The role of genetics in the determination of maximal exercise endurance is unclear. Six- to nine-week-old F2 mice (n = 99; 60 female, 39 male), derived from an intercross of two inbred strains that had previously been phenotyped as having high maximal exercise endurance (Balb/cJ) and low maximal exercise endurance (DBA/2J), were treadmill tested to estimate exercise endurance. Selective genotyp...

We examine the write endurance of USB flash drives using a range of approaches: chip-level measurements, reverse engineering, timing analysis, whole-device endurance testing, and simulation. The focus of our investigation is not only measured endurance, but underlying factors at the level of chips and algorithms—both typical and ideal—which determine the endurance of a device. Our chip-level me...

Very few sports use only endurance or strength. Outside of running long distances on a flat surface and power-lifting, practically all sports require some combination of endurance and strength. Endurance and strength can be developed simultaneously to some degree. However, the development of a high level of endurance seems to prohibit the development or maintenance of muscle mass and strength. ...
