Document Summary
Mid-term: monday, oct 24th: 25% (m/c) (50 mins: 25 questions. 13 (plus bonus) multiple, multiple: bring calculator, an hb pencil + eraser. Final exam: comprehensive: 50% (m/c) (2 hrs: ergogenic effects of selected substances, creatine. Effect: peak power during repeat 10 sec efforts increase significantly. Conditions: 6 exercise bouts that were 10 seconds in duration, with a 60 second recovery (x-axis) between each. Two conditions: creatine was given to athletes over 3 days or athletes were given a placebo over 3 days. 1 min is not enough time for recovery, because sprint #1 had the highest power & their power declined after every condition afterwards. Creatine allowed athletes to have higher peak power over the placebo athletes- over the repeated 10 second sprints: why? (mechanism) Performance enhancement due to increased muscle phosphor-creatine store. 8% increase of pcr/ atp under the supplement creatine.
