Lower body (legs): men and women have about the same strength. Creatine helps with power exercise up to 10sec (makes you bigger and stronger) High intake for a few days prior to exercise, extends time to exhaustion vs. high fat or mixed diets. Due to enhanced cho stores (both muscle and liver)- performed better, used more carbs to metabolize [graph]. Their performance was for a longer duration & higher intensity. Rq = respiratory quotient = the volume of co2 produced/amount of o2 consumed. It"s an index of what macronutrients fuel you are using : a ratio smaller than 1, means that you"re using something else rather than just carbs (like fats, since you"re consuming more oxygen, thus aerobic metabolism as well). A ratio closer to 1 (like 0. 95) you"re using mainly carbs as fuel. The longer the duration of the exercise, the more carbs consumed.
