The ratio of stroke volume to the volume of the chamber at the end of diastole is called a left ventricular ejection fraction (EF).
It is the most widely used and simplest expression of her features. The standard is 55 to 75%.
Blood pressure is influenced by a number of complex mechanisms of both central (fulfillment of cardiac chambers, heart muscle contractility) and peripheral (vascular properties).
Somanabolic Muscle Maximizer : We measure pressure systolic / diastolic. Values at rest 140/90 mm Hg or higher are known as hypertension, lower than 110/60 mm Hg in men and 100/60 mm Hg in women as hypotension.
Responding to the dynamic load
For dynamic load is characterized by cyclic loading with alternating tensing and relaxing muscle (isotonic muscle contraction).
It favorably affects blood circulation, supply nutrients and oxygen to the working muscles and exhaust residue metabolism.
Cardiovascular response values at this load depend largely on the type, intensity and duration of load and individual characteristics of the individual, and a number of external influences.
The reaction takes place in three stages. The initial phase is separated from physical capacity.
SF increases above the normal resting value to influence emotions and conditioned reflexes in the complex changes that we call the pre conditions.
It is observed a dependence on the expected performance of the load.
