The average person will take about 24 hours to plasma and approximately 4-6 weeks completely fill the red blood fills lost during blood donation. Since donating blood causes your body to experience a temporary decrease in red blood cells - the cells responsible for delivering oxygen to the muscles - blood donation can affect athletic performance. The application of too soon after the donation of blood may lead to bleeding of the location of the needle entry. In addition, the loss of fluid may be coupled to the loss of red blood cells, dizziness, and fainting.
How long after donating blood can i exercise as casual athletes?
The American Red Cross recommends individuals donating blood to wait until the day after blood donation - to undertake any form of exercise, both aerobic and anaerobic - a minimum of 12 hours. For example, if you donate blood at 6am, you must wait until at least 6 hours to work out the next day. However, some people have to wait up to 24 hours, depending on their gender, age, height, weight and blood circulation. If exercise is your first time after donating blood, try to wait at least 24 hours to be on the safe side.
How long after donating blood can i exercise as competitive athletes?
If you participate in general to exercise a high level of performance - such as marathon running or highly competitive sports - you may find that it takes five to seven days to return to normal levels of performance. Studies have shown that competitive cyclists blood performed at a submaximal level for about a week had given later, according to Dr. PA Lambeti (MBBCh) in an "Omega Bicycles" article. Therefore, if you are a competitive athlete, try to schedule your blood donations a minimum of seven days before a competition. If you are a regular blood donor, talk to your doctor about the long-term effects of iron deficiency on your athletic performance.
Return to practice
When you exercise, be alert for signs of dizziness or lightheadedness. Blood loss can cause decreased strength, so try to exercise no more than 75 percent capacity for the first few days after giving blood. Pay attention to your body; if you feel weak or exhausted, take a break or stop for the day. During a blood donation, your body loses fluid temporarily, to be replaced within about 24 hours. To avoid dehydration, especially if you exercise less than 12 hours after the donation, doubling fluids before, during and after exercise. Eat healthy, iron-rich foods to supplement the loss of iron which has experienced body. Exercise with a friend or a spotter for safety if you become dizzy or faint.
Exercising Before donating blood
If you do not want to miss a day of exercise, working out before you give blood, rather than afterwards. If you practice the day before or the day of your donation, be sure to drink plenty of fluids and eat a well-balanced, iron-rich meal before donating. This will help prevent dehydration and fainting during blood donation.
