athlete? Answer: 220 Liters per minute
◉ What is VO2max? Answer: the maximum amount of oxygen that
body can extract and use.
◉ How is VO2max measured? Answer: maximum volume of liters of
O2 per minute relative to body mass
◉ What are the two main factors that contribute to VO2max
efficiency? Answer: the heart's ability to distribute blood \n\nthe
muscles ability to extract and use oxygen
◉ What is EPOC oxygen used for? Answer: to bring the body back
into homeostasis
◉ Why is active recovery (cool down) important? Answer: supports
heart and circulatory system to redistribute blood to all body parts

,activities \n- improvement in oxygen delivery and extraction \n-
increased stroke volume \n- creased number and size of
mitochondria

◉ Smita is married and has one small child who is not in school yet.
She works full-time from her home office as a programmer/analyst
for a publishing company, which involves sitting at her computer for

exercise frequency? Answer: Number of session a client can commit
to \nClients current fitness level\ngoals for cardio training
◉ optimal aerobic training effects occur in how many training
session per week? Answer: 4-5
◉ Intensity refers to? Answer: the rate of work being performed
such as speed or relative load on the body ( % of HRmax)
◉ What are the three primary methods of planning and detecting
exercise intensity? Answer: oxygen uptake, HR monitoring and
precieved exertion
◉ HR increases linearly with? Answer: Oxygen Uptake
◉ Two primary ways to use HR for determining exercise intensity?
Answer: percentage of either HR max or reserve
◉ HRmax equation? Answer: HRmax = 220 - age
◉ What is the general target heart rate zone for HRmax? Answer:
55%-90%
