Venilatory and Lactate Threshold test!

so in my lab class for exercise physiology, i volunteered to be the test subject to test my venilatory and lactate threshold. i had to choose a pace that i could run at and maintain for an hour...( i was only on the treadmill for 20 minutes but it had to be something i could have done for an hour). i was running at 4.0mph and the treadmill was being inclined 1.5% every 3 minutes. i had nose plugs on and could only breathe through this mouth piece which was hooked up to a metabolic cart. i also had to do 2 finger pricks while running....it was actually kinda hard to have someone prick your finger and run at the same time. by the end of the test i was at an incline of 10%....it was pretty hard towards the end! the next day i had sores on the bottom of my gums from the mouth piece but it sure was worth it. it was really interesting to see all of my numbers at the end of my test. i am so mad i didnt take a picture of me hooked up to the machine, otherwise i would definitely have a picture with this post...so sorry!!!
