why do veins pop out when working out

Why do veins pop out when exercising? Do visible veins indicate a fit body? And more questions answered
Why do veins become visible? are an integral part of the blood circulatory system. They are blood vessels that carry the oxygen-depleted blood towards the heart, with the exception of the pulmonary and umbilical veins (which carry oxygenated blood). Usually, present just below the flesh, veins generally have a tendency to pop out if the amount of fat the body contains is less. Butб are they the sign of fitness? Drб Amit Pankaj, Additional Director Б Orthopeadics and Joint Replacement at Fortis Hospital Shalimar Bagh weighs in. Why do veins pop out in the first place? Generally, fat tends to layer the body thereby preventing the veins from protruding. In some cases, during extreme physical exertion, the veins are flattened and pushed to the surface of the body which makes them appear as though they are popping out. So, what makes the veins pop out during a workout?

Veins generally tend to be more visible and prominent when one is working out because the blood supply to the muscles increases tremendously. This leads to the veins becoming dilated which cause more blood to flow through them. This is a not good or bad thing because it is a result of the normal physiological mechanisms that can result from the rise in arterial blood pressure during exertion. The leaner you are, resulting in that the fact when you have less subcutaneous fat covering your muscles, the more pronounced your veins will look. This happens because fat is not present in the body, which leads to the veins becoming more visible and prominent. If there was fat present on the body, then the veins would not be so prominent. The blood tends to rush into the veins, pulsating and pushing causing the veins to come to the surface of the flesh as a result of which they have a tendency to look as though they have popped out. Therefore, people who have low levels of body fat will often have more prominent veins as their veins will tend to push and since they donБt have enough subcutaneous fat this these veins will bulge out against the surface and be visible.

Finally, what are the real benchmarks of fitness levels? 1. Low heart rate: resting heart rate should be around 70. 2. A person should perform high demand activities with ease and not get tired easily. 3. A person should not have much subcutaneous fat. Image source: Veins bulging from your body often look large, rigid and under high pressure. Many people assume this is the circulatory system's response to heightened demands resulting from exercise. Although exercise does have effects in the body that can change the appearance of your veins and arteries, it is not a matter of new ones appearing, or old ones enduring more stress. In fact, the appearance of veins under your skin when weightlifting has very little to do with the veins at all. Any type of exercise elevates the heart rate to some degree.

This is a physiological response to an increased need for oxygen in the body, particularly in locations where work is being performed. The heart rate and breathing rate increase to compensate for the increased work, which is fueled through blood flow to exercised locations, such as the muscles. The changes in the appearance of your veins actually has little to do with what occurs in the veins themselves, according to "Scientific American. " In fact, these effects in your veins are the product of changes in the muscle matter surrounding them. The body's plasma flows into muscles during exercise and causes them to swell and harden. The hardening of muscle pushes inset venous tissue to the surface of the muscles and against the skin, making it more visible, while the function of the veins remains largely unchanged. The long-held belief of the cause of bulging veins was that exercise forced the heart and circulatory system to distribute blood faster, leading to an increase of volume and pressure in the veins that pushed out venous walls and made them more rigid.

But more recent study of bulging veins has shown that pressure actually declines during exercise because circulation is improved throughout the body, distributing blood and putting less pressure on any one passageway. Volume also remains constant throughout the body and can increase in smaller capillaries while decreasing in larger vessels. Although bulging veins are a common by-product of exercise, you can also develop more prominent veins through potential hazardous health concerns. Heart disease can contribute to bulging veins and be a precursor to a heart attack, according to "Running Times. " Smoking also accentuates veins on the surface of the skin, as does excessive stress. Older individuals are more likely to develop bulging veins for this reason. If you are unsure about the cause of your bulging veins, call or visit a doctor.
