background and aim: in skeletal muscle, carnitine plays an essential role in the translocation of long-chain fatty-acids into the mitochondrial matrix for subsequent beta-oxidation. despite an abundance of literature describing the basic mechanisms of action of l-carnitine metabolism, there remains some uncertainty regarding the effects of oral l-carnitine supplementation on metabolism and exer...

the purpose of the present research was to examine the effect of one bout of exhaustive aerobic exercise with two different intensities on levels of serum mda in male smokers. for this purpose, 12 male smokers (age: 22.08 ±1.31 years, percent of body fat: 17.26 ±4.92% and body mass index: 23.21±2.96 kg/m2) were voluntarily selected and randomly participated in a crossover design in three situat...

introduction: ascorbic acid is a water-soluble vitamin solved in water that acts as a helper of some the enzymes in the reactions of energy metabolism. thus, the study aims to investigate the use of supplemental ascorbic acid on the aerobic and anaerobic capacity of the children.methodology: participants of this quasi-experimental study were 18 children in esfahan who were randomly selected and...

background: the purpose of this study was to investigate the effects of two types of rehabilitation techniques, including aerobic and strengthening exercises on patients with knee rheumatoid arthritis (ra). methods: 48 male patients with knee ra were randomly assigned into 3 groups, including aerobic exercises, strengthening exercise, and control. the two first groups completed their treatment ...

Cheuvront SN, Kenefick RW, Montain SJ, Sawka MN. Mechanisms of aerobic performance impairment with heat stress and dehydration. J Appl Physiol 109: 1989–1995, 2010. First published August 5, 2010; doi:10.1152/japplphysiol.00367.2010.—Environmental heat stress can challenge the limits of human cardiovascular and temperature regulation, body fluid balance, and thus aerobic performance. This minir...

in recent years, the effects of exercise on nervous system, spatial memory andmotor function in the senescence period have received the attention of researchers.as the age increases, some functions of nervous system such as spatial memory areweakened. thus, the effect of aerobic exercises including swimming and runningon learning, spatial memory and motor function was investigated in old rats. ...

Atlantic salmon Salmo salar smolts were exposed to one of the four different aerobic exercise regimens for 10 weeks followed by a 1 week final smoltification period in fresh water and a subsequent eight-day seawater transfer period. Samples of gill and intestinal tissue were taken at each time point and gene expression was used to assess the effects of exercise training on both branchial and in...

Introduction: Visfatin is predominantly secreted from visceral adipose tissue and mimics the effect of insulin by binding to insulin receptors. The purpose of the present research is to examine the effect of glucose intake on plasma visfatin concentration following an aerobic exercise session. Methods: In a quasi-experimental study, 16 male non-athlete students (21.91±2.31 yrs., 77.53...

background and aims: due to the anti-inflammatory properties of the ginger plant, it has attracted researchers’ attentions for treating menstrual problems. the aim of this study was to investigate the effect of a program which contains submaximal aerobic exercises and ginger on pain duration in the college girls with primary dysmenorrhea. methods: this quasi-experimental research was performed ...
