ACSM Certified Exercise Physiologist

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

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

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.

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.

Is the ACSM’s weekly recommended PA sufficient to prevent weight gain in the typical american lifestyle?
Hell na! They must go beyond these recommendations.

Two types of pre-participation self-guided screenings
1. PAR-Q (physical Activity Readiness Questionnaire)
2.Fitness Facility Pre-participation screening questionnaire

What is the PAR-Q? Limitation?
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?
Also useful for clients to assess their health readiness. More comprehensive and recognizes signs and symptoms of CVD and other risk-factor thresholds.

What is the SAID principle? What is it dependent on?
The specificity principle. Specific exercise elicits specific adaptations, creating specific training effects. (Specific Adaptations to Imposed Demands). Dependent on the TYPE and MODE of exercise. Example: a client wants to improve their time in an endurance run, you select training stimulus that is appropriate. (eg. endurance activities, not swimming.

7 ways of determining exercise intensity
1. Heart rate reserve method.
2. Peak HR method
3. Peak VO2. method
4. Peak METs method
5. VO2 reserve method
6. Talk test method
7. RPE method

(HRR) Heart rate reserve method KARVONEN FORMULA
The difference between max HR and resting HR.
Target HR = [(max HR -resting HR) X %intensity desired] + Resting HR.

Peak HR method
220-age = max HR. (SD of 12-15 BPM)
Target HR = max HR X % intensity desired

Peak VO2 method
must have measured or estimated VO2max.
Target VO2 = VO2max X intensity desired

Peak METs method
Target METs = (%intensity desired)(VO2max in METS -1) +1

VO2 reserve method
What is VO2 reserve?
VO2 reserve is the difference between VO2 max and VO2 rest. (determined in a lab setting)
Target VO2 reserve = [(VO2max – VO2 rest) x %intensity desired] + VO2rest

Talk test method
differentiates between moderate and vigorous activity. If they can talk, but not sing it is moderate. If they are unable to say more than a few words without pausing for a breath it is vigourous.

Borg’s RPE scale. What level is recommended to improve cardiorespiratory fitness?
ranges from 6 to 20. from no exertion at all to maximal exertion. 11 to 16 to improve CRF.

What is the CR-10 scale of exertion? (Borg’s category ratio scale)

Exercise in heat yields? (relate to HR as well)
Dehydration risk, increased blood flow to the skin (away from working muscles), HIGHER HR values.

Exercise in the cold yields?
Vasoconstriction of blood vessels in the skin, HR and cardiac output are similar to thermoneutral environment, wearing bulky clothing is a barrier, Respiratory rate is higher and VO2 max may be slightly lower. Some individuals may perceive exercise to be more difficult in the cold

Exercise in high altitude
“thin air” same amount of oxygen in the air at ALL elevations. It is the change in barometric pressure that causes the PO2 to decrease. SV decreases and HR increases during first initial days. Safe to assume that there will need to be a significant reduction in intensity and duration of activities.

acclimatization vs. acclimation
acclimatization – Physiological adaptation that occurs in response to a change in the “natural” environment.
acclimation – physiological adaptation that occurs in response to EXPERIMENTALLY induced changes in climate.

Heat acclimatization, cold acclimatization, altitude acclimatization benefits
Heat- lower core body temp, skin temp, high sweat rate, lower HR, lower perception of effort, improved conservation of sodium. (recommended 10 consecutive days in heat)
cold- maintain heat production by means beside shivering, maintenance of hand and feet temperatures.
altitude- Increases O2 carrying capacity in the blood. (Erythropoiesis, production of additional RBC) “live high” “train low” Benefits last up to 3 weeks.

initial simple assessment of muscular strength and change in muscular strength between clients (calculation)
(kg) weight lifted / (kg) body weight

What is a 1RM? Multiple RM? What equipment should be used?
1RM is the heaviest weight that can be lifted in 1 rep. using proper form and technique. STANDARD muscular strength assessment. multiple RM can provide an index of change over time. Performance is significantly greater on weight machines than free weights. Allow 3 to 5 minutes between trials. Obtain 1RM within 4 sets.

Muscular endurance assessments. How do you determine which test to use based on each client?
Curl-up and push up test. Based on the needs of the client. (poor ab strength is thought to contribute to low back pain.

What are the PROS principle of designing a resistance training program? What do they mean?

demands placed on the body must be continually and progressively increased over time. Increase at 5% to 10% per week and decrease the reps by 2 to 4 when a given load can be performed for the desired number of reps.

Resistance training must be performed on a regular basis several times per week to make gains. 2-3 per week.

to enhance muscular fitness, the body must exercise at a level beyond that at which it is normally stressed. Manipulated by changing the INTENSITY, DURATION, or FREQUENCY

SAID principle. Specific adaptations to Imposed demands. Distinct adaptations that take place as a result of the training program. Must mimics demands of their sport or desired goals.

Types of resistance training (3). Explain each.
DCER(isotonic)- most common. weight lifted does not change through the lifting and lowering phase of an exercise. the heaviest weight that can be lifted is limited by the strength of a muscle at the weakest joint angle.
Isokinetics- muscle actions performed at a constant angular limb velocity.
Plyometric training- enhances neuromuscular performance. quick, powerful movements that involve a rapid stretch of a muscle (eccentric) followed by a rapic shortening (concentric).

What is the amortization phase?
in plyometrics it is the amount of time it takes to change direction from eccentric to concentric. Should be as short as possible. (<0.1s) to maximize training adaptations.

Resistance training program variables.
Choice of exercise- promote balance across joints and between opposing muscle groups.
Order of exercise- Total body (perform more challenging first and large muscle groups first)
Resistance Load Used- Most important variables. Performed to muscle fatigue but not exhaustion.
Training Volume- number of exercises performed per session, reps performed per set, number of sets performed per exercise all influence training volume.
Rest intervals between sets- muscular strength (rest 2-3min) muscular endurance (rest <1min) repetition velocity-as individuals gain experience they may perform higher-velocity movements. Training Frequency- 2-3 x per week. Periodization- regularly changing the training stimulus to keep it effective.

4 types of flexibility training
1. Static- most common. slow constant motion held to the point of mild discomfort.
2. Ballistic- rapid bouncing movements. Used by coaches for athletes to increase blood flow before competition. Contraindicated.
3. PNF (proprioceptive neuromuscular facilitation)- combining passive stretching combined with concentric and isometric. need partner. GTO plays an important role.
4. Dynamic flexibility- slow controlled movements, sport specific that increase core temperature- relate to type of activity.

Muscle spindles
collection of 3 to 10 muscle fibers that are innervated by a motor neuron. Provide info about rate of change in a muscle.

What are Golgi Tendon Organs?
located in the musculotendinous junction. respond to changes in muscle tension.

Explain myotatic reflex reciprocal inhibition.
Myotatic reflex “stretch reflex” occurs in the stretched muscle by attempting to resist the stretch. Muscle spindles monitor muscle length. Helps keep us upright.

What is reciprocal inhibition?
*The antagonist muscle responds with reciprocal inhibition. Causes antagonist to contract less as the agonist contracts.

Flexibility assesments
sit and reach tests- most commonly used for flexibility in lower back and hip joint.
functional movement screens

Flexibility program designs
Flexibility gains are lost within 4 to 6 weeks of quitting exercises. 2-3 x per week for at least 3-4 weeks may be required. Do these exercises when the body is warm. hold to mild discomfort. NO link between ROM training and prevention of lowback pain or muscle soreness.

Coronary Artery disease
accounts for the most cardiovascular deaths. The most prevalent types of CVD.

Define athlerosclerosis
process where fatty streaks develop, causing the artery wall the thicken while reducing the luminal diameter. begins with a focal injury to the lining of the artery and eventually causes damage to the endothelium. The endothelium then becomes more permeable to lipids , allowing LDL’s to move easily through where they are oxidized by macrophages. creating fatty streaks and plaque formation begins.

Define myocardial ischemia
partial impairment of coronary artery artery blood flow reduces oxygen to cardiac tissue.

Define myocardial infarction
hEART ATTACK. results in heart tissue death.

stable ischemia vs. unstable ischemia
stable: result of increased O2 demand of the heart (as seen with exercise) increased chest pain (angina) and decreased exercise capacity because of reduced blood supply to the heart.

Social cognitive theory
first known as social learning theory. Emphasizes interaction between individuals and their environments.

one’s confidence in their ability to engage in PA. derived from social cognitive theory. The more confident one feels in their ability to succeed the more likely they are to engage in the behavior.

3 main factors that influence behavior and behavioral choices
1. the environment
2. individual personality characteristics
3. behavioral factos

self-efficacy can be influenced by 4 sources of information:
1. enactive mastery experience- successful completion of target behavior
2. vicarious experience- seeing a similar person complete the behavior
3. verbal persuasion- others express faith in the individuals capabilities
4. psychological affective states- increase positive emotional state about the activity

Key to social cognitive theory
focus on what they CAN do. not what they CAN’T do.

What is the social ecological model
comprehensive approach integrating multiple variables or layers that influence behavior. Each layer has an impact on the next.

2. perception of severity of threat
3. perception of benefits
4. perceptions of barriers to reduce health threat

What is the theory of planned behavior?
identifies intension as the primary influence determining behavior.
intension + perceived behavioral control

What is the self-determination theory?
Individuals have 3 basic psychological needs that must be met in order to be motivated to engage behavior. Autonomy and competence are key with this theory. The person must feel that they have a sense of control. Must also feel challenged yet successful.

what are those 3 psychological needs?
1. competence- feeling capable of mastering a task
2. relatedness- need to be connected and involved with the social world
3. autonomy- maintaining a perceived internal locus of control and a sense that behaviors are chosen freely.

extrinsic vs. intrinsic motivation.
intrinsic is more likely to maintain PA. Extrinsic is doing it for weight control, weight loss, and stress reduction.
