the aim of this study was to investigate the effect of 10 weeks of endurance training on nesfatin-1 levels and insulin resistance in women with type-2 diabetes. 16 women with type-2 diabetes were selected by purposive sampling method and randomly divided into experimental (n = 8) and control (n = 8) groups. the experimental group performed endurance training for 10 weeks, 3 sessions a week (wit...

Heart rate turbulence (HRT) is the return of heart rate to equilibrium after a premature ventricular contraction (PVC). It consists of a brief speed up period in heart rate, followed by a slow decrease back to the baseline rate. The concept of HRT was introduced to the medical community by Schmidt et al in 1999. While studying PVC characteristics researchers had noticed that heart rate seemed t...

Following 4 weeks on placebo, eighteen pateints with bradycardia-tachycardia syndrome (BTS) were treated with 100 mg xamoterol twice daily for 2-4 weeks. Ambulatory 24 h Holter electrocardiogram recordings showed that xamoterol decreased maximum heart rate from 140 ± 5.1 to 107 ± 6 beats min-' (P < 0.001) during exercise, increased minimum heart rate from 43 ± 1.7 to 51 ± 2.4 beats min-' (P < 0...

In cardiac rehabilitation, physical activity is essential, but the intensity of exertion as defined by the heart rate should be kept within specific limits. A heart rate monitor helps the user maintain the target range of physical exertion for maximum benefit. According to experts, visual heart rate display are often distracting and uncomfortable. In this paper, we present the results of a less...

Accepted for publication 28 July 1997 Abstract Objective-To estimate the training load of specific on court training regimens based on the magnitude of variation of heart rate-lactate response during specific training and to determine the magnitude of variation of biochemical parameters (urea, uric acid, and creatine phosphokinase (CPK)) 12 hours after the specific training programme so as to a...

Most vertebrates increase cardiac output during activity by elevating heart rate with relatively stable stroke volume. However, several studies have demonstrated 'intrinsic autoregulation' of cardiac output where artificially increased heart rate is associated with decreased stroke volume, leaving cardiac output unchanged. We explored the capacity of noradrenaline to overcome autoregulation in ...
