HARD DECK ch 7, 8, 12, 15, 2, 3, 4 Flashcards
At rest how many mL of O2 do we consume per kilogram of body weight per minute? What’s another word for this?
3.5mL
1 MET
How much is one MET? What does MET stand for? What does MET mean?
1 MET = 3.5 mL Oxygen/kg body weight/min
MET: Metabolic equivalent
One MET is resting Vo2 (Oxygen consumption)
What is Systolic blood pressure?
What is a healthy range?
What is Diastolic blood pressure?
What is a healthy range?
Systolic - Pressure within the arteries as/after the heart contracts. (sy from “syn” meaning together)
<120 mm Hg
Diastolic - Pressure within the arteries when the heart is resting and filling with blood.
<80 mm Hg
Where are the Atria?
What do they do?
Describe right versus left functions.
- Top of the heart
- Collects blood returning to the heart
- Right Atrium: deoxygenated from the entire body
- Left Atrium: oxygenated from the lungs.
What is the path of blood travels through in relation to the heart?
Oxygenated blood, red, travels from the lungs to the left atrium (top Left). It then fills the left ventricle (bottom) before being pushed out to the body.
Deoxygenated blood, blue, returns to the heart from various body segments through the right atrium (top right). From the right atrium the blood travels through the right ventricle and out to the lungs to be be saturated with oxygen.
List 3 Behavioral Strategies to Enhance Exercise Adherence and generally describe each. (you’ll describe each in more detail later)
- Self-Management-managing one’s own behavior, thoughts and emotions
- Self-Monitoring-daily written record of behavior
- Goal Setting-
a. Assessing current level
b. Creating s.m.a.r.t. goal for future levels
c. Detailing the actions
Affirmations versus Compliments
- Compliments are more “I like” statements and create an EXTERNAL advantage point
- Affirmations are more “you are” statements and creates an INTERNAL client attribute
- Affirmations show appreciation for clients and their strengths
- Important to genuinely affirm something the client PERSONALLY VALUES (about client’s thoughts, plans or skills) rather than clothes, sneakers, HR monitor, etc
- P.T. must LISTEN CAREFULLY to know what to affirm
What is SELF-MANAGEMENT?
What are 2 benefits?
Name 5 helpful self-management skills for improving exercise adherence. (how to)
- Managing one’s own:
1. behaviors
2. thoughts
3. emotions
and changing what’s not working.
Benefit:
1. Improves ability to MONITOR and CHANGE WHAT ISN’T WORKING
- COPING WITH and adapting LIFESTYLE CHANGES and DIFFICULTIES THAT might OTHERWISE SHORT-CIRCUIT PLANS to exercise regularly
associated with beginning or returning to exercise
How-To:
- Goal Setting
- Self-Monitoring
- Positive Self-Talk
- Psyching UP
- Imagery
How can the client have passion, inspiration and focus from their goals?
What questions can help achieve this?
If the goal is an extension of their values
What long term accomplishments do I want? 6 mo, 1 year, next 5 years, and my dream accomplishment
Should short term or long term goals be established first?
Long
In communication with clients, the goal should not be to communicate information but what instead?
Goal should be to build a relationship through a genuine interest in getting to know them.
Communicate with understanding more than information
List the 3 components of the warm-up for the: -STABILIZATION level, -STRENGTH level, -POWER level of the OPT model.
- Self Myofascial Release
- Stretching:
a. Static (stabilization)
b. Active-isolated (strength)
c. Dynamic (power) - Cardio
What is AUTOGENIC INHIBITION?
- < 7 sec, or 6-15 sec, but Nasm says 30 sec
- GTO Relaxes the agonist, and the spindle
- Static Stretching
What two techniques are used in CORRECTIVE Flexibility? Why is one used before the other?
- Self-myofascial release 2. STATIC STRETCHING Once the knot or adhesion has calmed down, its easier to re-establish length in the muscle.
What two techniques are used in FUNCTIONAL Flexibility? Why is one done before the other?
- Self-myofascial release 2. DYNAMIC STRETCHING To get our bodies ready for the movement.
What are Open-Chain Exercises?
Involve movements in which the distal extremities (hands and feet) are not in a fixed position and the force applied by the body is great enough to overcome the resistance (such as barbells or Dumbbells)
Bench Press Lat Pulldown The Machine Leg Extension Exercise
What are Closed-Chain Exercises?
Involve movement in which the distal extremities (hands and feet) are in a constant fixed position and thus the force applied by an individual is not great enough to overcome resistance (such as the ground or an immovable object).
Push-Ups Pull-Ups Squats
What is Sarcopenia?
Age-related loss of skeletal muscle mass
What is Osteopenia? How does it effect the body?
- Loss of bone density - Increases likelihood for fractures and other acute and chronic skeletal disorders such as osteoporosis
What is the LEFT exercise?
2 Cones 10 yards apart, running between the two in various combinations, 7 times (SAQ exercise)
What is the MAXIMAL HEAR RATE METHOD for prescribing exercise intensity?
208 - (70% of age) = Heart rate max
Which of the following two definitions is of Active Isolated Stretching, and which is Dynamic Stretching?
The active extensions of a muscle, using force production and momentum, to move the joint through the full available range of motion.
Active Stretching–The process of using agonists and synergists to dynamically move the joint into a range of motion.
Dynamic Stretching–The active extensions of a muscle, using force production and momentum, to move the joint through the full available range of motion.
Force-Velocity Curve
- The relationship of muscle’s ability to produce tension at differing shortening velocities.
- Velocity of concentric muscle increases, ability to produce force decreases (results thought to be bc overlapping filament may interfere with its ability to form cross bridges with myosin)
- Velocity of eccentric muscle action increases, the ability to develop force increases (results thought to be b/c elastic component of the connective tissue surrounding and within the muscle).
Give examples of Force-Couples for:
Trunk rotation
Upward rotation of scapula
Hip and knee extension during stair climbing
Plantar flexion
Shoulder Abduction
- Muscles: Internal and External Obliques; Movement: Trunk Rotation
- Muscles: Upper trapezius and the lower portion of the serratus anterior; Movement: upward rotation of scapula
- Muscles: Gluteus Maximus, quadriceps, and calf muscles; Movement: produce hip and knee extension during walking, running, stair climbing, etc.
- Muscles: Gastrocnemius, peroneus longus, and tibialis posterior Movement: Performing plantarflexion at the foot and ankle complex
- Muscles: Deltoid and Rotator Cuff Movement: performing shoulder abduction
Give examples of first, second, and third class levers in the HMS.
What force is in the middle for each lever?
Which do most limbs operate as?
1st Class -Fulcrum in middle like a seesaw
(nodding head where the top of spinal column is fulcrum).
2nd Class -Resistance in the middle with fulcrum and the muscle’s effort on either side, like a load in a wheelbarrow(because when you lift a wheelbarrow the effort is on the handles and the fulcrum is on the opposite end with gravity in the middle).
(push-up or calf raise - where the ball of foot is fulcrum, body weight is resistance, effort applied by calf musculature).
3rd Class-Effort in the middle between resistance and the fulcrum -The effort always travels a shorter distance and must be greater than resistance,
(forearm- fulcrum is elbow, the effort is applied by the bicep muscle which attaches slightly outside of the elbow, the load is in the hand like dumbbell when performing bicep curl).
-Most limbs in human body operate as third class levers
Isotonic Muscle Action/Contraction
-Constant muscle tension -Force is produced, muscle tension develops, and movement occurs through a given range of motion. -Two types: Eccentric and Concentric
What is the use of O2 to form Pyruvic Acid (versus lactic acid) in the production of ATP
Aerobic Glycolosis! =D
What is the ATP-PC System?
What makes it significant?
Is it aerobic or anaerobic?
How long does it provide energy for?
When is it activated?
What are two activities that would use this system?
- The process of creating a new ATP molecule from a phosphocreatine molecule.
- The simplest and fastest of energy systems
- Occurs without the presence of oxygen (anaerobic)
- Provides energy for Approx. 10-15 seconds
- Activated at the onset of exercise, regardless of intensity, b/c of its ability to produce energy very rapidly in comparison with the other systems.
- Strength training, or sprinting
What is glycolysis?
Is it aerobic or anaerobic?
What is its duration?
Why is glycolysis signifiant (2 reasons)?
What is the end result?
- A means of producing ATP through chemical breakdown of glucose.
- Anaerobic
- Approx. 30-50 seconds duration
- Lasts about 8-12 repetitions so most workouts will put greater stress on this system.
- CREATES SIGNIFICANT AMOUNT OF ENERGY (2 ATP per glucose, 3 ATP per glycogen)
- End Result: *Glucose or Glycogen broken down into Lactic Acid (anaerobic glycolysis) or Pyruvic Acid (aerobic glycolysis)
EXTRA:
-*Glucose/Glycogen must be converted to glucose-6-phosphate before glycolysis can occur. *converting glucose to glucose-6-phosphate uses 1 ATP molecule *convert glycogen to glucose-6-phosphate does not
What is the Oxidative System (oxidative phosphorylation)?
What are its defining characteristics in terms of simplicity/complexity, speed, and longevity?
When is it used for energy?
What is its main fuel source?
- The process of creating energy or ATP with oxygen and substrates (mainly fat)
- The most complex of the the energy systems for generating ATP
- Speed is not its strong point (gradually increases over at least the first 5 minutes),
- But can produce for an indefinite amount of time (b/c everyone has ample fat storage)
- Used at rest for indefinite periods of time and during sustained exercise
What are the 3 Oxidative/Aerobic Systems?
- Aerobic Glycolosis - use of O2 to form Pyruvic Acid (versus lactic acid in regular anaerobic glycolosis)
- The Krebs Cycle - Pyruvic Acid converted into Acetyl Coenzyme A (Acetyl CoA) and oxidized to produce 2 units of ATP and by-products CO2 and hydrogen, hydrogen then is combined with other enzymes
- The electron transport chain (ETC) - first two processes then provide energy for the oxidative phosphorylation of ADP to form ATP
What is the anaerobic threshold?
The point where the body can no longer produce enough energy with normal oxygen intake
What is the difference between Type I and Type II muscle fibers in size and speed to fatigue? What is another name for each of them?
Type I - Slow Twitch- smaller, and slower to fatigue
Type II - Fast Twitch - longer and quick to fatigue
