Narrowing of the coronary lumen due to plaque build up that results in the development of Atherosclerosis.
Leading cause of death in the U.S.?
Cardiovascular Disease (CVD)

age and physical activity.
if unchecked Coronary Artery Disease (CAD) results in what two diseases?

Pain or discomfort in the chest,originating behind the sternum, and radiates through theshoulders, arms (one or both), neck, and jaw.

- aka Heart Attack. Occurswhen heart muscle is deprived of oxygen.
- Blockage of the coronary artery causes decreased blood flow(ischemia); Accompanied by pain radiating down one or botharms, shortness of breath, …
- Results in damaged heart muscle (see Figure 4.8).
what is a Thrombus?
A clog in a coronary artery
what are the three benifits of Exercise training after the heart has been damaged or is known to have CAD?
- Improve strength of the heart.

- ↑ VO2MAX.
What is the Angina threshold definition?
Theexercise intensity at which blood flow cannot meet thedemands of the heart and angina occurs.
What is the defintion of Peripheral Vascular Disease?
Vascular diseases are those that affect the arteries andveins outside of the heart.
what are teh 3 syptoms of Peripheral Vascular Disease?

- Numbness, weakness, “heaviness” in affected limb.
- Toe and foot sores that do not heal.
What are the 2 things that Hypertension is caused by?
- ↑ blood flow from heart
- ↑ resistance to flow through arterial blood vessels.
What is Systolic BP (SBP)
Highest pressure inarteries; Occurs during contractionphase (i.e., systole) of the cardiac cycle.
What is Diastolic BP (DBP)?
Lowest pressure inthe arteries; Occurs during therelaxation phase (i.e., diastole) of thecardiac cycle.
What is congestive heart failure?
- Weakening of the heart muscle pump
- Enlargement of the heart via stretching and thinning of the walls
- Results in fluid accumulation in periphery and or lungs
What is Metabolic Syndrome (MS)
- A clustering of specific metabolic risk factors
- No universally accepted criteria for defining MS.
- Common to look for 3 or more of the following:
- High waist circumference.
- Elevated blood triglycerides.
- Low HDL (“good”) cholesterol.
- Elevated fasting blood glucose.
- Having MS puts you at higher risk
What is the science that interprets therelationship of food to the functioning of theliving organism?
what is The study of factors affectinghealth and disease prevalence in largegroups of people?
What does NHANES stand for?
National Health and Nutrition Examination Survey.
whan did NHANES begin?
waht provides observational data regarding the current nutritional practices of U.S. citizens?
how often is it administered?
Whar Requires an individual to report their dietary intakeover the previous 24 hrs
What is dietary recall also known as?
what Requires an individual to the types and amounts offoods consumed over 2-7 successive days?
What are the three macro nutrients?
Simple sugars are called.....
Glucose is a.......
Disaccharide – e.g., Sucrose, Maltose, Lactose
Polysaccharides – e.g., Glycogen
are they a simple or complex carbohydrate?
what is the process of breaking triglyceridesinto its constituent components called?
where does Lipolysis occur?
Glycerol and fatty acid are transported to…
1. Liver – for further processing.2. Adipose tissue – for storage.
The presence of high levels of fat in the blood is called?
Cholesterol comes from what two sources?
Produced in liver or intestines; Consumed in diet.
The presence of high levelsof cholesterol in the blood is known as?
How many different types on amino acids are there? how many are essential?
22 and 9
The process of breaking down the body’s “stored”protein is known as?
The process of building new structures within thebody from simpler molecules is known as?
How much carbohydrate does a person need toeat within a day?
- General recommendations:
- ≤ 5 g/kg/day Sedentary to low active people
- 7 g/kg/day Moderately active people
- ≥ 10 g/kg/day Highly active people
How much protein should be eaten on a daily basis?
- 0.8 g/kg/day Average “inactive” person
- 1.2 – 1.7 g/kg/day Highly active people
what percent of the body is composed of water?

≥5% dehydration [ ]
- 1% dehydration [Thirst ]
- 2% dehydration [ Dehydration]
- 3% dehydration [ Exercise performance impaired]
- ≥5% dehydration [heat exhaustion, heat stoke ]
What is The study of the action of forces on particles and mechanical systems; a branch of physics?
what is the Application of the principles of mechanics to the study of living organisms (e.g.,the human body and its parts) called?
Science which describes and predicts the
conditions of rest or motion of biological
systems under the action of forces.The application of mechanical physics to
what is The study of motion with special
reference to describing patterns of movement
and the speed of movement for the body and/or the limbs called?
name the planes:
- 1) sagittal
- 3) Transverse
what is The study of the forces acting on or produced by the body called?
whats the other name and definition?
- The is the study of designing equipment and devices that fit the human body, its movements, and its cognitive abilities..
what is the name of the body position lying down face up in the anatomical position?
What is the name of the body position when the body is face down lying down in the anatomical position?
Toward the midline.
Away from the midline
Toward the head.
towards the feet
Closer to the trunk.

What are the 3 axes of motion called?
- vertical or longitudinal
what is the name of the axes of motion that passes from side to side at right angles to the sagittal plane (e.g., back flip).
What is the name of the axes of motion that passes horizontally from front to rear lying at right angles to the frontal plane (e.g., cart wheel).

Vertical, or Longitudinal
These are diagrams used to show the relative magnitudeand direction of all forces acting upon an object in agiven situation.
Resistance of humans moving through the air.FD α (velocity)2
Aerodynamic Drag (FD):
Aerodynamic Drag (FD): three rakings
- < 12 MPH; FD is small (negligible).
- 12‐18 MPH; FD is moderate.
- ≥ 18 MPH; FD is high.
Refers to resisting the gravitational attraction between the Earth andyour body.
- Gravity (FG):
- FG α Total mass in system
Static Friction (FST)
- Resistance between two objects to NOT slide
- FST must be great enough to hold two objects together.
Rolling Friction (FR)
- Resistance to an object rolling over a surface.
- FR is often a function of movement speed – Thus, faster rollingobjects experience more FR. This force is usually very small.
Normal Force (FN):
- The force applied by the ground upward to the body in response to FG.
- FN α FG
Applied Force (FA):
- Refers to a force applied to an object by the body. This is considereddifferent from gravitational force which accounts for the body“pushing” on the ground.
- E.g., Leaning on a wall – FA applied to the wall.
- E.g., Vertical jump – FA applied to ground, which is in addition to FG.
Propulsive Force (FP):
This is the net force, or the resultant force vector,
Type of force that brings to surfaces orobjects directly together
Type of force that tends to elongate an object
Tensile Force –
Type of force that causes an object or surface toslide over another.
