It was a semi-experimental study. Thirty six men [age: 21.48 (0.25), and BF%: 27.39 (0.52)], voluntarily participated in this study after public announcement in univer...

[ 9 ] - Acute and Short-Term Effects of Oral Feeding of Jujube Solution on Blood Platelets and its Morphological Indices in Response to a Circuit Resistance Exercise

The present study investigated the acute and short-term effects of oral feeding of jujube solution on blood platelets and its morphological indices in response to circuit resistance exercise. Fourteen young male volunteer students were randomly divided into the placebo and jujube solution groups. All participants performed one circuit resistance exercise[9stations/nonstop, 30 seconds for each s...

[ 10 ] - Short-Term Effects of Oral Feeding Jujube Ziziphus Solution before a Single Session of Circuit Resistance Exercise on Apoptosis of Human Neutrophil

The aim of present research was the effect of short-term use of edible solution of jujube one week before a single session of circuit resistance exercise on neutrophil apoptosis of male students of physical education. 14 young male volunteer students were divided into two groups of placebo (n=7, aged 24.50±2.50, height 171.17±1.70, and weight 67.51±4.92) and jujube solution...

[ 11 ] - The Effect of a Single Session of Eccentric Resistance Exercise on Some Parameters of White Blood Cells

It is reported that resistance exercise causes an elevation of white blood cells (WBC) and some of its parameters such as neutrophils (NUT) and lymphocytes (LYM) but there isn’t enough study about eccentric exercise (ECC). So, the purpose of this study was to investigate the effect of a single session of eccentric resistance exercise on some parameters of white blood cells. Twelve volunte...

[ 12 ] - Effect of Pyramidal Training on Plasma Lipid Profile and Fibrinogen, and Blood Viscosity of Untrained Young Men

The present study examined the effects of progressive exercise (pyramidal) short-term program on plasma fibrinogen, lipid profile and blood viscosity in untrained young men. Changes and imbalances in homeostasis lead to cause of heart attacks. There is conflicting information about the effect of exercise on these factors. 19 young healthy untrained men were randomly assigned to the exercise gro...

[ 13 ] - Effects of Eight Weeks Circuit Resistance Training on Pulmonary Function of Inactive Women
