Chapter 20: Program Design for Aerobic Endurance Training Flashcards
maximum amount of oxygen the pulmonary, cardiovascular and muscular systems can use during a certain period of intense exercise
max aerobic capacity or power
VO2max
true or false: as the duration of an aerobic endurance event increases, so does the proportion of the total energy that must be supplied by aerobic metabolism
true
there is a high correlation between what two things in aerobic endurance events?
VO2max and performance
highest percent of VO2max without accumulating lactate
lactate threshold
a measure of the energy cost of activity at a given exercise velocity
exercise economy
an improvement in ______ ________ can enhance maximal aerobic power or VO2max and lactate threshold
exercise economy
elite runners have a lower/higher stride frequency and shorter/longer stride length
higher stride frequency
shorter stride length
what type of training improves exercise economy and technique?
interval training
heart rate and oxygen consumption are closely related between what percentage range of VO2max?
50-90% VO2max
why are heart rate and oxygen consumption not closely related about 90% of VO2max?
oxygen debt
using more energy than oxygen consumed
oxygen debt
