Drink a lot before and after donating For replacing the blood cells you don't need so much energy but iron, keep that in mind especially if you are female or vegetarian Your stamina will suffer the most, keep endurance exercise on a lower ...

Interesting question. If considered 1 hour training - running can be better. Why? You burn much more calories then in other trainings, so your blood needs to deal with all of that. I mean oxygen, nutrition, and removing wastes. My heart says it works pretty hard, when I run, sometimes trying to escape... For shorter trainings - rowing? or maybe stationary ...

-Pub med actually has graphs on this. "Brain activity after physical activity" i believe is what I typed in. - I joined stack exchange almost 5 minutes ago.. So, Please be patient with me! I am trying to add a link to this study. However, I am unsure of the best way to do that at the moment. - (I did take the tour but the method explained has not worked ...

Christian's answer is good for blood donations. While I haven't donated in over a decade, my understanding is that there hasn't been many changes in the taking of plasma. When one donates plasma, they filter out the plasma and return everything else so you aren't losing any red blood cells. Then in the end, they pump in a bag of saline to help replenish the ...

Any exercise which increases blood circulation in general; cardio! Bicycling, swimming, sex, running/jogging, aerobics, wrestling, football, basketball... You get the point. Also, mental exercise. Try solving a Rubik's Cube. Do some puzzles like crossword or sudoku. Meditation is also very helpful for things like this. Cut down on any distinctively bad ...

Heart rates can trend lower in a pool, because your body is horizontal and your heart is not fighting gravity to get blood back up from the extremities. It's along the same principle as your heart rate is lower when lying down than when standing. As far as the cardiovascular, a high heart rate does not automatically increase your cardio fitness. It's ...

Interesting question. I'll try to go though all possible explanations / answers. Years ago there was a theory that muscle soreness comes from too much acid, produced by metabolism. That is not true. If trained enough - weakest fibers in muscles will be broken. That makes body reacting like on infection. So for that it would not help, since it is not an acid,...

Sound like you are used to a stronger stimulus than the one normally archieved without supplements. Stop taking this stuff and after after a few weeks, when you are used to training without any pump, do carboloading the day before workout and try isometric exercise. Its a bit like you are used to drink a lot of coffee to wake up and now wondering why a cold ...

Your question assumes that each blood type offers a different capacity to carry oxygen. Without going into scientific explanations, the easiest way to answer the question is to understand the role of Hemoglobin. Hemoglobin is a protein that serves as a transport mechanism to deliver oxygen to the body tissues. VO2Max is a measurement of how quickly the ...

Sounds pretty drastic. Maybe ingesting something like a fruit slushy, a Slurpee/Icee, or even just blended ice and some water would do the trick, as normal blood flow in and around the stomach-full of slushy ice-liquid would even out that temperature differential and cool down the body. Beware of brain, neck and back freeze, though. That's what I do, ...
