Effects of Caffeine and Aspirin on Runners?
So I've been doing some research and I've found taking caffeine and aspirin in combination has postive effects on speed/endurance on runners.
Caffeine helps increase the users energy if only for a few hours (long enough for a race).
When you take aspirin with it, it helps thin the blood so more caffeine can enter the blood stream as the blood is thinner making it easier to enter into.
Today I took 4 Vivarin (800mg caffeine) at 1 hour before practice and 2 Aspirin (650mg) at 1 hour :45 min ran.
Out of 3 miles, my first two were approx. 2 - 1.5 minutes faster than my average but on the 3rd mile I became extremely dizzy and fatigued and had to take a few minutes of rest. I then continued to run it but at a reduced pace as I was worried for my health.
What my questions are is what is the most efficient combination of dosages of these two drugs for a cross country runner?
How long before the run to do ingest?
Is it worth taking the Aspirin to make the caffeine more effective or is the thinning of the blood (does that cause dizziness?) not worth the effect that it gives?
It seems I have trouble breathing properly when I'm running at the increased pace that I'm not used to, do I need to learn how to breathe correctly or is my respiratory not developed (conditoned) enought to run at this speed?
(I probably will think of more questions in the future, there's so many variables please add anything you think would help.) Thanks.
Why do I seem to die on the 3rd mile when I'm under the effect of "Caf-spirin" and how do I stop this? Take less of the drug or condition more?
It seems I'm really fast for the first two but I'm dead by the 3rd, does the drug wear off when I'm running hard or what?
How can I make it last longer if so?
Would taking Ephedrine improve my running performance then? and if so what dosage as I heard it can be lethal.
I know it used to be avalable at 24mg but now only at 8mg per tablet, and much more expensive.
