ACSM Certified Exercise Physiologist,
Top Exam Questions and answers, 100%
Accurate, VERIFIED.

Physical Activity - ✔✔-Any bodily movement produced by contracting skeletal muscles, with an increase
in energy expenditure.

Exercise - ✔✔-Planned, purposeful, repetitive

Physical Fitness - ✔✔-Attributes or characteristics that individuals have achieved that related to their
ability to perform physical activity

3 metabolic pathways the body uses to creates ATP - ✔✔-1. Creatine Phosphate

2. anaerobic glycolysis

3. 0xidative system

Claudication - ✔✔-pain in the leg is induced by exercise, usually because of an artery obstruction.

Creatine Phosphate system - ✔✔-Small amounts of CP are stored within each cell. Simple one-to-one
trade off that allows for the rapid production of ATP. ONLY for use during short bouts of exercise. less
that 10 seconds.

Anaerobic glycolysis - ✔✔-No oxygen required. NExt most immediate energy source. break down carbs
(glucose or glycogen) into pyruvate. Used during medium-duration exercise. no more than about 90
seconds.

Aerobic glycolysis (oxidative system) - ✔✔-Oxygen dependent. As exercise intensity decreases allowing
for longer duration activities, use of the oxidative system increases. (Krebs cycle and ETC). Produce ATP
in the mitochondria of the cell--requires oxygen. Lasts longer than 1-2 minutes.

,What is VO2? - ✔✔-The volume of oxygen the body consumes. VO2 max is the highest volume of oxygen
the body can consume.

Define Stroke Volume - ✔✔-the volume of blood the heart ejects with each beat.

How does SV increase with workload? - ✔✔-Similar to HR, it increases as workload increases but only up
to ~40% to 60% of VO2max. The percentages can be decreases in sedentary individuals and increased
with training.

What happens to resting HR as stroke volume increases? - ✔✔-it decreases, as more blood being
pumped per beat allows the heart to beat less often.

What is cardiac output? - ✔✔-a measure of blood pumped per minute. The product of stroke volume
and heart rate.

What does Diastolic Blood pressure do during exercise? - ✔✔-Remains stable or decreases slightly.

What is rate pressure product? - ✔✔-serves as an estimate of myocardial oxygen demand. Product of
HR and Systolic BP. HR X SBP

What is the Fick equation used to determine VO2 max? - ✔✔-VO2max = HRmax X SVmax X a-VO2
difference max (arteriovenous oxygen difference)

What is the gold standard to measure Cardiorespiratory fitness? - ✔✔-VO2 max during open circuit
spirometry.

How does a submaximal exercise test work? - ✔✔-It estimates VO2 max from the HR response to
submaximal single stage or graded exercise.

,absolute oxygen consumption vs. relative oxygen consumption - ✔✔-absolute is the raw volume of O2
consumed by the body. Relative is the volume of O2 consumed relative to body weight. Useful to
compare fitness levels between individuals.

What is one of the largest components of PA-related energy expenditure? - ✔✔-Occupational Physical
Ativity

5 Health related physical fitness components - ✔✔-Cardiorespiratory endurance, body composition,
muscular strength, muscular endurance, and flexibility

6 Skill (performance) related physical fitness components - ✔✔-Agility, coordination, balance, power,
reaction time, and speed

cardiorespiratory endurance - ✔✔-ability of circulatory system and respiratory system to supply o2
during sustained physical activity

Body composition - ✔✔-relative amounts of muscle, fat, bone, and other vital parts of the body

Muscular strength - ✔✔-Ability of muscle to exert force

muscular endurance - ✔✔-ability of muscle to continue to perform without fatigue

flexibility - ✔✔-ROM at a joint. as per the skeletal muscles and not any external forces.

Agility - ✔✔-ability to change position of the body in space with speed and accuracy

coordination - ✔✔-ability to use the senses together with body parts to perform tasks smoothly and
accurately

balance - ✔✔-maintenance of equilibrium while stationary OR moving

, reaction time - ✔✔-time elapsed between stimulation and the beginning of the reaction to said stimulus

speed - ✔✔-ability to perform a movement within a short period of time

ACSM's weekly/daily physical activity recommendations - ✔✔-150 minutes Moderate PA per week (30
min or more most days of the week), 75 minutes of vigorous intensity

Can most sedentary individuals safely begin a low-to moderate intensity PA Program without the need
for baseline testing or medical clearance? - ✔✔-Yes indeed

Most common musculoskeletal injuries occur in what area of the body? - ✔✔-lower body- particularly
the knee or foot

Who is most at risk for sudden cardiac death? - ✔✔-Sedentary individuals performing infrequent
exercise

Light PA is defined as - ✔✔-<3 MET's

Moderate PA is defined as - ✔✔-3 to <6 MET's

Vigorous PA is defined as - ✔✔->/=6 MET's

What is 1 MET? Why do we use METs? - ✔✔-1 MET = the relative oxygen consumption at rest. or, 3.5
mL per kg per minute. It is an easy way for the general public to gauge their exercise intensity. Also used
to calculate energy expenditure over time.

What is a kilocalorie? what is it also known as? - ✔✔-AKA: Calorie. estimate of energy cost that can be
directly related to physical activity and exercise. Weight gain, loss and maintenance can be estimated
remembering that 3,500kcal =1 lb of fat.
