Feeling dizzy at the end of a race or training is something a good number of runners have experienced. It is something relatively common, and most of the time it represents nothing serious.
Dizziness is often common in some people by suddenly stopping after running. This is mainly due to a drop in blood pressure.
Why does it happen?
“As you run, the blood vessels dilate, the muscles contract and the heart pumps faster to meet the energy demand of running,” said Dr. Cathy Fieseler, a sports medicine doctor at CHRISTUS Trinity Mother Frances Health System, a regional health care provider based in Tyler, Texas.
When a runner crosses the finish line or stops at the end of his workout, the heart loses the pumping assistance of these muscles. With dilated blood vessels and no return pumping action, blood quickly accumulates in your limbs, which causes blood pressure to decrease, the expert said.
“The effort of the race can also mean a lower fluid intake during the competition. This minimal fluid intake, combined with strong sweating, results in a lower volume of blood, which means lower blood pressure, ”he added.
To reduce dizziness at the end of running, the expert-recommended runners to keep moving after crossing the finish line or finishing their training.
“Continue walking if possible and, if not, raise your legs as if you were marching or walk in your place for several minutes. You can also contract the muscles of the upper body by clenching your fists or clasping your palms, ”he noted.
Another tip is to drink water or drinks that can help you recover faster. During workouts, the ideal is to carry a drink and start drinking immediately to replace lost fluids and electrolytes.
In addition, wearing compression socks can help with the venous return to the heart, so its use is welcome.
Also, it is always advisable to include a cooling phase after finishing any run, to allow the body to return to normal. This time allows the heart rate to decrease gradually and, most importantly, allows the blood flow to be redistributed from a state of exercise to a state of non-exercise.
Finally, Fieseler advised to consult with a doctor and talk about these symptoms if dizziness after running is very frequent.
