هدف از انجام این پژوهش بررسی تأثیر مصرف مکمل کافئین بر شاخص خستگی و فشار خون در ورزشکاران هوازی و بی­هوازی مرد بود. نمونه آماری شامل 32 مرد سالم از بین ورزشکاران هوازی(16 نفر، سن2±24 سال) و ورزشکاران بی­هوازی (16 نفر، سن3±25 سال) بود که با طرح دوسوکور، به 7 نفر از هر گروه به جای کافئین پلاسیبو یا دارونما داده شد. جلسة اول آزمون رست (پیش‌آزمون)، بعد از گذشتن حداقل 4 ساعت از صرف غذا انجام شد. جلس...

 Background and Objective: Visfatin is a recently discovered adipokine. Previous studies have shown a direct relationship between plasma visfatin levels and type 2 diabetes mellitus. The current study was conducted to investigate the effect of aerobic exercise on plasma level of visfatin in type 2 diabetic men treated with metformin. Materials and Methods: Thirty-six men with type 2 diab...

Background: 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 (three sets of 5 repetition at 85% of 1-RM with 3-min rest between sets), hyperthrophy (three sets of 10 repetition at 70% of 1-RM with 2-min rest...

Background and Objective: Visfatin a 491 amino acid peptide is expressed as a Pre-B cell colony-enhancing factor or Nicotinamide phosphoribosyltransferase and might be  regulated by several factors such as nutritional status, physical stress, suggesting a regulatory role of peripheral visfatin in energy homeostasis. The purpose of the present study was to investigate the effects of endurance t...

 Background: Visfatin is a newly characterized adipokines which is highly expressed in visceral adipose tissue and may play a role in insulin resistance. The aim of this study was assessing the effect of 12 weeks aerobic exercise on Visfatin level and insulin resistance in obese women. Methods: This study was a semi-experimental research. Twenty obese volunteer women (age 37±9.89 yr, bo...

    Introduction : visfatin is a protein with insulin-like functions that secretes from adipose tissue and has been linked to obesity and insulin resistance, but the effect of exercise training on visfatin levels is unknown. The purpose of study was to compare the effect of aerobic and resistance training on plasma visfatin levels in type 2 diabetic women.   Material and Methods : 45 women with...
