ACSM Certified Exercise Physiologist
exam questions with correct answers
Physical Activity -Correct Answer-Any bodily movement produced by contracting skeletal muscles, with an increase in energy expenditure.
Exercise -Correct Answer-Planned, purposeful, repetitive
Physical Fitness -Correct Answer-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 -Correct Answer-1. Creatine Phosphate
2. anaerobic glycolysis
3. 0xidative system
Claudication -Correct Answer-pain in the leg is induced by exercise, usually because of an artery obstruction.
Creatine Phosphate system -Correct Answer-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 -Correct Answer-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) -Correct Answer-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? -Correct Answer-The volume of oxygen the body consumes. VO2 max is the highest volume of oxygen the body can consume.
Define Stroke Volume -Correct Answer-the volume of blood the heart ejects with each beat.
How does SV increase with workload? -Correct Answer-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? -Correct Answer-it decreases, as more blood being pumped per beat allows the heart to beat less often.
What is cardiac output? -Correct Answer-a measure of blood pumped per minute. The product of stroke volume and heart rate.
What does Diastolic Blood pressure do during exercise? -Correct Answer-Remains stable or decreases slightly. What is rate pressure product? -Correct Answer-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? -Correct Answer-VO2max = HRmax X SVmax X a-
VO2 difference max (arteriovenous oxygen difference)
What is the gold standard to measure Cardiorespiratory fitness? -Correct Answer-VO2 max during open circuit spirometry.
How does a submaximal exercise test work? -Correct Answer-It estimates VO2 max from the HR response to submaximal single stage or graded exercise.
absolute oxygen consumption vs. relative oxygen consumption -Correct Answer-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? -Correct Answer-Occupational Physical Ativity
5 Health related physical fitness components -Correct Answer-Cardiorespiratory endurance, body composition, muscular strength, muscular endurance, and flexibility
6 Skill (performance) related physical fitness components -Correct Answer-Agility, coordination, balance, power, reaction time, and speed
cardiorespiratory endurance -Correct Answer-ability of circulatory system and respiratory system to supply o2 during sustained physical activity
Body composition -Correct Answer-relative amounts of muscle, fat, bone, and other vital parts of the body
Muscular strength -Correct Answer-Ability of muscle to exert force
muscular endurance -Correct Answer-ability of muscle to continue to perform without fatigue
flexibility -Correct Answer-ROM at a joint. as per the skeletal muscles and not any external forces.
Agility -Correct Answer-ability to change position of the body in space with speed and accuracy
coordination -Correct Answer-ability to use the senses together with body parts to perform tasks smoothly and accurately
balance -Correct Answer-maintenance of equilibrium while stationary OR moving
reaction time -Correct Answer-time elapsed between stimulation and the beginning of the reaction to said stimulus
speed -Correct Answer-ability to perform a movement within a short period of time
ACSM's weekly/daily physical activity recommendations -Correct Answer-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? -Correct Answer-Yes indeed
Most common musculoskeletal injuries occur in what area of the body? -Correct Answer-lower body- particularly the knee or foot
Who is most at risk for sudden cardiac death? -Correct Answer-Sedentary individuals performing infrequent exercise
Light PA is defined as -Correct Answer-<3 MET's
Moderate PA is defined as -Correct Answer-3 to <6 MET's
Vigorous PA is defined as -Correct Answer->/=6 MET's
What is 1 MET? Why do we use METs? -Correct Answer-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? -Correct Answer-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.
Is the ACSM's weekly recommended PA sufficient to prevent weight gain in the typical american lifestyle?
-Correct Answer-Hell na! They must go beyond these recommendations.
Two types of pre-participation self-guided screenings -Correct Answer-1. PAR-Q (physical Activity Readiness Questionnaire)
2.Fitness Facility Pre-participation screening questionnaire
What is the PAR-Q? Limitation? -Correct Answer-A minimal standard for entry into Moderate-intensity exercise programs. allows individuals to gauge their own medical readiness to participate . does not screen well for those at low to moderate risk.
What is a pre-participation screening questionnaire? -Correct Answer-Also useful for clients to assess their health readiness. More comprehensive and recognizes signs and symptoms of CVD and other risk-
factor thresholds.
What are the ACSM Coronary Artery Risk factors? -Correct Answer-Age (Men 45 and older women 55 and older), Family History (MI, coronary revascularization or sudden death before 55 in father and 65 in mother or first degree relative), Smoker (current or quit within the last 6 months), Sedentary (no PA in at
least 30 minutes of MPA at least 3 days per week for the last 3 months), Obesity (BMI 30 or over, or waist
girth >40in for men and >35in for women), Hypertension (SBP 140 or more and/or DBP 90 or more confirmed on 2 seperate occasions), Dyslipidemia (LDL 130 or more OR HDL <40. OR on lipid lowering meds), Prediabetes (Impaired FBG between 100 and 125.)
What is the negative risk factor? -Correct Answer-HDL value of greater than or equal to 60. (this is reverse cholesterol transport and reduces the risk of CVD)
Dyspnea -Correct Answer-Shortness of breath
