NAFC 5 2025/2026 Exam Questions with
100% Correct Answers | Latest Update
Aerobic - 🧠ANSWER ✔✔To be aerobic means to be "with oxygen," and one
must engage in an activity that promotes the supply and use of oxygen.
The cardio-respiratory system consists of the lungs, arteries, veins, heart,
and blood within the body. Exercise is developed to stimulate muscle
contractions, hence training the muscles to promote various health goals.
Aerobic (cardio) training requires uninterrupted rhythmic movements using
large muscle systems to increase delivery of oxygen throughout the human
body. The oxygen delivery system improves with aerobic training and is
called aerobic capacity. Aerobic capacity improves with each of the
following variables:
••
The ability to breathe in large volumes of air
, ••
The ability to deliver large amounts of blood to tissues
••
The ability to effectively transport blood to the entire body
••
A powerful heart and healthy vascular system is a direct reflection of
improving aerobic capacity and is currently the best measure of physical
fitness
Anaerobic - 🧠ANSWER ✔✔Training continually at too high of a pace or not
training hard enough to stay within specified training intensity can render
the exercise an anaerobic activity. Anaerobic exercise consists of activity
that requires an all-out effort and can only be performed for short periods of
time.

This flushes more oxygen into the body than can be used and creates an
oxygen deficit. The oxygen deficit leads to an increased lactic acid build up
within the muscle and could be the cause for exercise exhaustion
