The purpose of the present study was to elucidate the influence of intermittent hypobaric hypoxia at rest on endurance performance and cardiorespiratory and hematological adaptations in trained endurance athletes. Twelve trained male endurance runners were assigned to either a hypoxic group (n = 6) or a control group (n = 6). The subjects in the hypoxic group were exposed to a simulated altitud...

research has shown that chronic, long and exhausting endurance training programs cause iron deficiency. this problem can have a negative effect on physical performance. the aim of this research was to study the effect of endurance training and iron supplement on anemic indexes [hemoglobin (hb), hematocrit (hct), red blood cell (rbc), total iron binding capacity (tcbc) and ferritin], and cytochr...

BACKGROUND Most researches were focused on chemical constituents and bioactivities of Pedicularis. However, there were a few reports on simultaneous determination of the series phenylpropanoids compounds in Pedicularis by High Performance Liquid Chromatography (HPLC). OBJECTIVE To establish an HPLC method for simultaneous determination of salidroside, verbascoside, iso-verbascoside, leucosept...

OBJECTIVES Repetitive manual handling tasks account for a substantial portion of work-related injuries. However, few studies report endurance time in repetitive manual handling tasks. Consequently, there is little guidance to inform expected work time for repetitive manual handling tasks. We aimed to investigate endurance time and oxygen consumption of a repetitive lift and carry task using lin...

Here we report on the effect of combining endurance training with heavy or explosive strength training on endurance performance in endurance-trained runners and cyclists. Running economy is improved by performing combined endurance training with either heavy or explosive strength training. However, heavy strength training is recommended for improving cycling economy. Equivocal findings exist re...

UNLABELLED BACKGROUND Quercetin is a natural polyphenolic compound currently under study for its ergogenic capacity to improve mitochondrial biogenesis. Sedentary mice have exhibited increased endurance performance, but results are contradictory in human models. METHODS We examined the effects of six weeks of endurance training and quercetin supplementation on markers of endurance performa...

Flash memory technology is becoming critical in building embedded systems applications because of its shock-resistant, power economic, and non-volatile nature. Because flash memory is a write-once and bulkerase medium, a translation layer and a garbage collection mechanism is needed to provide applications a transparent storage service. In this paper, we propose a real-time garbage collection m...

the subjective of this study was to explore and compare the effects of whole body vibration (wbv) and conventional spinal stabilization exercises on persons with non-specific chronic low back pain (clbp). thirty patients with non-specific chronic low back pain randomly received 6 sessions of spinal stabilization therapy with and without whole body vibration over 2 weeks. the severity of pain, f...

Increment of lipoprotein(a) [LP(a)] Concentration, as a coronary artery disease risk factor. Probably LP(a) not been affected by physical activity and it is resistant against exercise stimulation. The aim of this cross-sectional study was to determine and compare of LP(a) concentration in selected groups. This analytical study was designed in three groups of subjects (15-25 yrs) who were volunt...
