Alright I have a test coming up and I am pretty much fucked. We were supposed to have a review but all this Austin crazy shooting business canceled that school day so we are just going to take the test without a review. So I am trying to do some extra credit that will help me pass the class since I am going to bomb the test. If any smart sherdoggers could help that would be awesome. Question: James and Mike have the exact same PR times for a 10km running. When they got tested in an exercise physiology lab, James lactate threshold was 25% higher than Mikes. Why do they have the same running performance?
