NCSF UNIT 3 EXAM QUESTIONS AND
ANSWERS
Delayed-onset muscle soreness is experienced among new exercisers.. - Correct
Answers -48 hours following exercise
Low-intensity aerobic training programs are ineffective for reducing body fat among
physically-active clients - Correct Answers -Because low rate of caloric expenditure
Neural rehearsal via movement practice - Correct Answers -improves movement
efficiency and proprioception
90 seconds - Correct Answers -The minimal rest time needed between broad jump
assessments to fully replenish ATP stores
Static stretching - Correct Answers -The process of passively taking a muscle to the
point of tension and holding the stretch for a minimum of 30 seconds, has the potential
to reduce power output
Isometric contractions - Correct Answers -Muscle contracts but there is no movement,
muscle stays the same length.
Blood pressure is a product of.. - Correct Answers -heart rate and peripheral resistance
Nervous system - Correct Answers -the first system to adapt to exercise
The breakdown of what biological energy source results in the production of lactic acid?
- Correct Answers -glucose
Glycolysis - Correct Answers -the breakdown of glucose by enzymes, releasing energy,
and pyruvic acid.
lactic acid - Correct Answers -the byproduct of glycolysis, triggering an elevation in
respiration rate
Glycogen - Correct Answers -The only energy substrate that can be metabolized
aerobically or anaerobically to produce ATP
Cardiac output - Correct Answers -heart rate x stroke volume
