Introduction: Obesity is linked to cardiovascular diseases, characterized by endothelial dysfunction, the optimal mode of exercise for controlling obesity of high-intensity interval training or moderate-intensity continuous training has is the however not yet been determined. Materials and Methods: A total of 33 inactive and overweight women, aged 40-50 years with body mass index over 27kg/m2 w...
از آنجا که تطابق(adaptation) به هیپوکسی ناشی از زندگی در ارتفاعات نتایج مثبتی را بر عملکرد قلب داشته، آیا می توان با ایجاد هیپوکسی مزمن ناشی از سیانید، مقاومت قلب در شرایط ایسکمی را بالا برد؟ در پاسخ به این سوال روی ratهای نر بالغ در دو گروه تست (n32) و شاهد(n10) صوزل گرفت . در مدت 5 هفته به گروه تست روزانه 1/7 mg/kg سیاتید و به گروه شاهد با حجم مساوی سالین نرمال به شکل داخل صفاتی تزریق شد. سپس...
It is difficult to estimate the maximum in vivo aerobic ATP production rate of the intact heart independent of limitations imposed by blood flow, oxygen delivery, and maximum mechanical power. This value is critical for establishing the kinetic parameters that control oxidative phosphorylation, as well as for providing insights into the limits of myocardial performance. In this study, the maxim...
The assessment of harsh working conditions requires a correct evaluation of the metabolic rate. This paper revises the basis described in the ISO 8996 standard for the evaluation of the metabolic rate at a work station from the recording of the heart rate of a worker during a representative period of time. From a review of the literature, formulas different from those given in the standard are ...
Twenty eight subjects (mean age 64 years) who had been treated for tuberculosis by thoracoplasty in the past performed an increasing work rate exercise test, from which maximum oxygen consumption (VO2max), ventilation and heart rate were measured. VO2max was significantly lower than predicted, being 0.75 l/min in 17 subjects, 1.0 l/min in 10, and 1.5 l/min in one. Only one subject achieved a he...
