    Measuring haemodynamic variables using different techniques and examining the effects of diving reflex‚ isometric muscle contraction and psychological stress on these variables. Introduction Haemodynamics is the study of factors that determine the movement of blood (Widmaier et al‚ 2011). The main haemodynamic factors are heart rate and blood pressure. Heart rate is defined as the number of times the heart contracts per minute. Normal resting heart rate in adults ranges between 60 – 100 beats
