What is the DEFINITION OF EXERCISE PHYSIOLOGY.
100
A Motor Neuron and the Myofibrils it innervates.
What is a MOTOR UNIT.
100
The Cardiovascular System can be divided into these two distinct CIRCUITS.
What are the PULMONARY and SYSTEMIC CIRCUITS.
100
What happens to blood flow distribution as the intensity of exercise increases.
What is IT GETS DIVERTED MORE TO THE WORKING MUSCLES (AND LESS TO OTHER SYSTEMS LIKE THE DIGESTIVE SYSTEM).
100
EPOC stands for:
What is EXCESS POST-EXERCISE OXYGEN CONSUMPTION.
200
The Parasympathetic Nervous System's main function is to...
What is REVERSE WHAT THE SYMPATHETIC NERVOUS SYSTEM HAS DONE AND RETURN THE BODY TO HOMEOSTASIS.
200
The most easily accessed source for a Phosphate molecule to quickly convert ADP back to ATP.
What is CREATINE PHOSPHATE (PHOSPHOCREATINE).
200
What happens to BLOOD LACTATE as the intensity of an exercise increases and why?
What is IT INCREASES DUE TO THE INCREASED NEED FOR ATP PRODUCTION FROM THE ANAEROBIC LACTIC SYSTEM WHICH PRODUCES, AS A BY-PRODUCT, LACTIC ACID.
200
Even though the resting CARDIAC OUTPUT might be the same for a trained and untrained person, how is it different?
What is THE STROKE VOLUME (HIGHER IN TRAINED) AND HEART RATE (LOWER IN TRAINED) ARE DIFFERENT.
200
When the command to cease muscle contraction comes from the Nervous System, the first step inside the Sarcomere is to do what?
What is ACTIVELY PUMP CALCIUM IONS BACK INTO THE SARCOPLASMIC RETICULUM.
300
The area of the Sarcomere that gets smaller during a concentric contraction and where the Myosin is only found.
What is the H-ZONE.
300
The __________--> ____________ --> _____________ sequence of muscle contraction is known as the Cross-Bridge Cycle.
What is BOND --> BEND --> BREAK
300
CARDIAC OUTPUT is a Product of:
What is HEART RATE and STROKE VOLUME (Q = HR x SV)
300
AVO2 difference increases in efficiency from about ___% at rest to ____% during maximal intensity.
What is 25% --> 75%
300
Bioenergetic Conversion is:
What is THE BREAKDOWN OF THE FOOD WE EAT INTO THE 3 MACRONUTRIENTS: CARBOHYDRATES (GLUCOSE), FATS (LIPIDS), and PROTEINS (AMINO ACIDS).

What is CARBON DIOXIDE, WATER, AND HEAT.
400
Fast Twitch (Type IIa) Muscle Fibres rely on this Energy System for ATP Production.
What is the ANAEROBIC LACTIC/GLYCOLYTIC SYSTEM.
400
Two Central Factors that can improve VO2 Max through training are:
What are: HEART SIZE (STROKE VOLUME), INCREASE IN BLOOD PLASMA VOLUME (RBCs & HEMOGLOBIN), and MUSCLE CAPILLARIZATION.
400
The only Arteries in the body to carry 'de-oxygenated' blood.
What are PULMONARY ARTERIES.
400
The Greatest Arterial Blood Pressure.
What is SYSTOLIC BLOOD PRESSURE.

Calcium binds to sites on the _________________________ causing Myosin Active Sites to be exposed.
What is TROPOMYOSIN.
500
The Pathway for a Reflex Arc (5).
What is: SENSORY RECEPTOR --> AFFERENT (SENSORY) NERVE --> INTERNEURON(S) --> EFFERENT (MOTOR) NERVE --> EFFECTOR ORGAN (MUSCLE)
500
Provide 3 Causes of Physical Fatigue.
What are: DEPLETION OF PRODUCTS TO PRODUCE ATP, ACCUMULATION OF BY-PRODUCTS FROM PRODUCING ATP, NEURAL TRANSMISSION FACTORS, CEREBRAL PERCEPTION OF EXERTION AND LEVEL OF FATIGUE.
