Background. Fatigue has an undesirable effect on the continued exercise performance and decreases athlete's activity. Fast lactic acid disposed is high of importance for athletes. Objectives. Therefore, the present article determines the effects of the different frequencies of whole-body vibration after a strenuous activity on blood lactic acid. Methods. 60 athletes were chosen from sel...

various researches on laboratory and field scale illustrate that manipulating the ionic composition and the ion concentration of injected water can affect the efficiency of water flooding and the interaction of injected water with rock and other fluids present in porous media. the objectives of this paper are to investigate parameters that affect low salinity water flooding; mainly the effect o...

Diabetes is associated with abnormal autonomic function and increased mortality. Abnormal heart rate recovery after exercise, a measure of autonomic dysfunction, is also associated with increased mortality. The objective of this study was to determine the association of fasting plasma glucose with abnormal heart rate recovery and its prognostic importance in healthy adults. We studied 5,190 hea...

Objectives: Heart rate recovery (HRR) after exercise is clinically important as a predictor of mortality. In addition, HRR an indicator cardiac autonomic activity, since increased vagal activity and diminished sympathetic return the heart to resting conditions exercise. The previous attempts model using polynomial, first-order second-order modelling have produced mixed results. this study, we h...
