objectives: improvement in cancer care increases life expectancy of patients with cancer, most of whom have experienced prolonged episodes of fatigue during and after their treatment. this has been found to reduce the quality of life and increase morbidity and mortality of such patients. therefore, additional interventions are beneficial to improve overall quality of life as well as longevity. ...

fat oxidation during exercise can be influenced by exercise intensity and duration, training status, diet and physical activity level. however, few studies have investigated the effect of time of day on the rate of fat oxidation during exercise. thus the present study was designed to investigate the effect of time of day on indexes of fat oxidation in active young women. for this purpose, 14 he...

objectives: wheelchairs are the prime mobility aid of persons with spinal cord injuries. manual wheelchair propulsion puts a lot of demand on the cardiopulmonary as well as the skeletal system. the main purpose of the study was to compare the effects of both arm ergometry training and progressive resistance exercise training of upper limbs on resting heart rate and distance covered during wheel...

background: this study examined the applicability of trans-theoretical model (ttm) to understand exercise behavior among female college students in hamadan university of medical sciences, iran in 2007. methods: a cross-sectional descriptive study was conducted. the dependent variables analyzed were exercise efficacy expectation, decisional balance (pros and cons). the independent variable was s...

Naturally, deformed rocks commonly contain crack arrays (joints) forming patterns with systematic relationships to the large-scale deformation. Kinematically, joints can be mode-1, -2 or -3 or combinations of these, but there is no overarching theory for the development of the patterns. We develop a model motivated by dislocation pattern formation in metals. The problem is formulated in one dim...

We extend the mechanism for noise-induced phase transitions proposed by Ibañes et al. [Phys. Rev. Lett. 87, 020601 (2001)] to pattern formation phenomena. In contrast with known mechanisms for pure noise-induced pattern formation, this mechanism is not driven by a short-time instability amplified by collective effects. The phenomenon is analyzed by means of a modulated mean field approximation ...

the aim of the present study was to investigate the effect of two programs of standard sets and circuit weight training with different intensities on response of excess post exercise oxygen consumption (epoc) in young men. for this purpose, twelve healthy men (mean±sd: age, 21.92±1.1 years; height, 175.17±4.55cm; weight, 69.74±7.5kg) were voluntarily selected and participated in two stages of t...

background: stabilization exercises can improve the performance of trunk and back muscles, which are effective in the prevention and treatment of low back pain. the four-point kneeling exercise is one of the most common types of stabilization exercises. this quasi-experimental study aimed to evaluate and compare the level of activation between abdominal and lumbar muscles in the different stage...

fasting induces short-term physiological adaptations which spare the body's remaining carbohydrate stores and mobilize lipid stores to provide a substitute fuel for many tissues and organs, especially skeletal muscle. rodent studies show that regular occurrence of fasting then refeeding, stimulates adaptations in muscle which make the animal better placed to withstand a further period of fastin...

We analyze pattern formation in doubly resonant intracavity second-harmonic generation in the presence of competing nondegenerate parametric downconversion. We show that for positive cavity detuning of the fundamental frequency the threshold for parametric oscillation is lower than that of transverse, pattern forming instabilities. The parametric oscillation strongly modifies the pattern dynami...
