Introduction
I am Hiwa, a passionate researcher committed to advancing our understanding of exercise physiology. At Shahid Beheshti University in Iran, my focus centered on investigating platelet function in heart patients, resulting in several publications. Currently, I am pursuing my academic journey at Memorial University, where my research has shifted to the fascinating area of neurophysiology. My current focus revolves around exploring the complex dynamics of corticospinal neural excitability.

The aim of this study was to investigate the effects of 12 weeks of high-intensity training with astaxanthin supplementation on adipokine levels, insulin resistance and lipid profiles in males with obesity. Sixty-eight males with obesity were randomly stratified into four groups of seventeen subjects each: control group (CG), supplement group (SG),...
Original Article Abstract Purpose: The purpose of this study was to investigate the anthropometric, somatotype and physical fitness characteristics of medal winners in the twelfth students' athletic games and compare their characteristics with national champions in the same sport to determine the difference between athletes at two different levels...
Objective
To determine the effects of different intensities of interval resistance training (IRT) protocols on the levels of select myokines (decorin, follistatin, myostatin, activin A, transforming growth factor beta-1 [TGF-β1]), and cardiometabolic and anthropometric measures in males with obesity.
Methods
Forty-four obese males (age: 27.5 ± 9.4...
The effects of acute consumption of L-Arginine (L-Arg) in healthy young individuals are not clearly defined, and no studies on the effects of L-Arg in individuals with abnormal body mass index undertaking strenuous exercise exist. Thus, we examined whether supplementation with L-Arg diminishes cardiopulmonary exercise testing responses, such as ven...
Background:
Platelet activation is associated with abdominal obesity and exercise training is an important modulator of body weight.
Objective:
We investigated the effects of two high intensity interval exercise (HIIE) protocols of different intensity and duration on platelet indices and platelet aggregation in overweight men.
Methods:
Ten ove...
In this article we have provided a summary of the previous research that had investigated the interaction between exercise (acute and chronic) and platelets response, also we have provided some suggesstions for future studies.
BACKGROUND: L-Arginine, the precursor of NO might be involved in improving the cardiovascular disorders via regulation of functional properties of erythrocytes.
OBJECTIVE: This study investigated the effects of L-Arginine supplementation on responses of red blood cell (RBC) properties to high intensity interval exercise (HIIE).
METHODS: Ten overwei...

The aim of this study was to compare the effects of four weeks of cross-fit and traditional training during pre-season general preparation period on physical fitness of soccer players. For this purpose, 20 soccer players (age, 19.35±2.03 yrs; height, 173±3cm; weight, 66.2±2.9kg) with at least 2 season experience of playing in national leagues were...
Background:
The effects of high intensity interval training (HIIT) on inflammatory markers and endothelial function have been extensively shown. However, the acute effect of HIIT on platelet activation and function in patients with recent revascularization is unclear.
Objective:
The purpose of present study was to compare the responses of platel...
Introduction: The aim of the present study was to investigate the responses of plasma visfatin to resistance exercise intensity and its relationship with insulin resistance index, IL-6 and growth hormone. Methods: After familiarization and determining the maximum strength (1-RM), fifteen healthy young subjects (age: 26/2±9/1yr, weight:75/1±4/1 ) pe...
Purpose: The aim of this study was to compare responses of Visfatin and insulin resistance index to various resistance exercise protocols. Methods: Ten healthy male subjects performed three resistance exercise protocols including maximal strength (3 sets of 5 repetition at 85% of 1-RM with 3-min rest between sets), hyperthrophy (3 sets of 10 repeti...
Introduction:The purpose of this study was to investigate the effects of age on the responses of serum visfatin and insulin resistance index to a single session of endurance exercise. Materials and methods: For this reason, 45 male subjects were allocated to three age groups (n=15) of young (20-30 yr), middle-aged (40-50 yr) and old (60-70 yr). Aft...
Abstract
The purpose of this study was to investigate the relationship between resting visfatin levels and visfatin changes during endurance exercise with aerobic fitness and body composition. For this purpose, forty six subjects (Mean±SD; age, 42.8±16.0 y; height, 171.7±5.4 cm; weight, 73.6±9.7 kg) participated in this study. In one session after...
The purpose of this study was to investigate the relationship between resting serum visfatin with aerobic fitness and Insulin Resistance (IR). For this purpose forty six subjects with Mean±SD; Age 42.8±16.0 y, Height 171.7±5.4 cm and Weight 73.6±9.7 kg had been examined. After determining the maximal oxygen consumption (Vo2max), in separate session...
Abstract: The aim of this study was to investigate the effects of mountaineering on older age’s cardiovascular
and physical fitness factors and quality of life factors. Forty three healthy elderly men (age 57.7 9.3) were ±
randomly selected through questionnaires that had been distributed in the parks of northern of Tehran.
According to their activ...

I am doing a research on CABG Patients. I measuring their platelet aggregation before and after 8 weeks of HIIT training. But %platelet aggregation (with ADP) is relatively low (less than 10 percent). this values for platelet aggregation in other research is about 30-40%. Is there a problem with my data?
For my thesis, I should use (inVitro ) epoprostenol (Flolan) as platelet inhibitory drug, but I did not find the appropriate dose and method to adding Flolan after washing the platelet to preparing the sample for western blotting.
I would like to design High Intensity Aerobic Interval Training for overweight males. I would like to know the time and intensity of intervals and scientific reason for this type of training. Recently Gibala et al. suggested low volume and high intensity interval training. Based on this report, this kind of training along with its time benefits, have good effects on fat loss and metabolism. But I think that is very exhausting and intolerable especially for fat or overweight people and that we should use training with longer time and a little lower time. Any suggestions?
Some researchers believe that thrombin in some situation can play an inhibitory role in platelets by activating PKAc.
