Today was my first treadmill trial at OU. I took my "mystery drug" 2 hours before the start and showed up at the lab ready to run. They took all sorts of bodily fluids from me before we started and attached an HR monitor and body core temp reader to me (which read the sensor I swallowed earlier). They set da 'mill at 6.3 mph which is 60% my max speed from my VO2 max test and I ran for exactly one hour. Then they took more samples and I did a performance trial which was similar to my VO2 max test sans headgear/facemask and heavy tubing which made it MUCH easier! I maxed out at 10.8 mph for 1 min after having the speed bumped up 0.5 mph every minute. Total time for performance trial - 10 minutes. More samples taken and then I had to donate my clothes (which will be returned) and got all the sweat rinsed off me (COLD!!!).
I felt totally fine during the treadmill trial. Oddly enough, after rinsing the sweat off, toweling dry and dressing, I started to overheat pretty badly. I had to sit down with a fan right on me and have some ice applied to the back of my neck. I sucked down quite a bit of Gatorade too. It only took a few minutes to get back to normal.
I'm going to have to guess the capsule I took is the placebo unless the diuretic and anti-diuretic are so mild that I wouldn't notice their effects, which I suppose is entirely possible. I didn't feel any different during the trial. Didn't need to urinate, didn't feel excessively thirsty, didn't feel bloated - just normal. We'll see if I can tell a difference during the next trial!
