What are the two leading causes of death in the United States that are diseases that are considered lifestyle related and mostly preventable?
Cardiovascular diseases (high blood pressure, coronary heart diseases, congestive heart diseases, stroke) and Cancer (especially lung).
What are some key factors contributing to the increasing prevalence of obesity and excessive body weight in the United States?
High cholesterol (which is blood lipids, like fatty acids), Sedentary lifestyle due to technology
What is cardiovascular disease and who does it affect?
Cardiovascular disease is a broad term used to describe a range of diseases that affect the heart or blood vessels, it's any disease within the cardiovascular system (blood, heart, blood vessels). More than 35% of all deaths in the US are related to cardiovascular disease. Some cardiovascular diseases are high blood pressure, coronary heart disease (fatty deposits narrow the arteries), congestive heart disease and strokes. It affects people with high blood pressure, usually overweight, can be hereditary.
Familiarize yourself with cholesterol, blood pressure, diabetes, and other common diseases in America.
Cholesterol is related to cardiovascular disease and obesity. Cholesterol is a type of blood lipid, and are carried in the blood stream via high (good) and low (bad) density lipoproteins. A total healthy cholesterol is below 200. High is up to 239, and high risk level is over 240. High Blood Pressure occurs under stress and when the arteries are clogged in the heart due to clots and blockages related to blood lipids.
Diabetes: Type I is due to the fact that pancreas (which regulates blood sugar) quits working and so there is not enough insulin produced and so blood sugar is not delivered to the cells, which leads to hyperglycemia (high blood sugar), and it also doesn't produce glucose so it cannot prevent getting too low. Type II is associated with obesity because the cells have become insulin resistant (because they're blocked by fat often), but their bodies produce enough insulin, so still, blood sugar doesn't get into the cells.
Cancer: Often lung cancer, caused by smoking.
What is the recommended amount of physical exercise?
1: Moderate activity for 30 minutes a day for five days a week
2: Intense activity for 20 minutes a day three times a week, and resistance training two times a week

Familiarize yourself with the different fitness assessments and what each one measures. What does a comprehensive fitness assessment involve and what is its role in health management?
A fitness assessment is a systematic problem-solving method that provide an individual with information on where and how to start and maintain an excercise program, this way needs and status can be compiled. Physiological assessments provide a wealth of information regarding overal health, and a guideline as to how to acheive peak physical fitness. Two examples: assessing resting heart rate (lower heart rate= more strong, efficient heart, should be from 60-80 BPM) and blood pressure (uncontrolled high blood pressure can lead to stroke, heart attack/failure, kidney failure) Systolic: pressure produced by heart to pump blood thru body. Diastolic is the minimum pressure within the arteries through a full cardiac cycle. Different ways to assess fitness: Resting Heart Rate, Blood Pressure, BMI, Cardiorespiratory efficiency, Flexibility, and Muscular Endurance, Postural Assesment.
Body composition can be an indication of risk for certain diseases. How can body composition be used as part of a fitness program?
Body Composition Assesments help to determine if an individual's weight and fat percentages are healthy. People with too much fat are at risk for high blood pressure/cholesterol, diabetes. It can help determine whether a person needs to lose weight/fat and what kind of excercise to do.
What is BMI?
BMI: Body Mass Index, used to determine if an individual's weight is appropriate for their height. BMI is either calculated via a proportion of height and weight or a machine (underwater weighing, electropulse thing). Healthy BMI is 18.5-24.9, doesn't diferentiate between fat and lean body mass.
What is the difference between overweight and obese?
Overweight is a person who has a BMI of 25-29.9, and who is 25 to 30 lbs over the recommended weight for height. Obesity is the condition of being considerably overweight, with a BMI of 30 or more, and who is at least 30 lbs greater than their recommended weight.
What kind of information is gained from a postural assessment?
Posture is important for body efficiency and injury prevention. A postural assessment determines whether their are postural distortions. Distortions indicate weak muscles and imbalances, and recognizing them allows individuals to fix them. There are lower extremity postural distortions, lumbo-pelvic-hip postural distortions, and upper extremity postural distortions. Improving posture allows the body to function properly, increase flexibility and strength potential and reduce chances of injury.
Question 1: By gathering information through the fitness assessment, a fundamental representation of all of the following can be determined for an individual EXCEPT
Question 2: When measuring the carotid pulse, excessive pressure can decrease blood pressure leading to all of the following EXCEPT

What are the 3 macronutrients? Why is it important to consume appropriate amounts of each?
The three macronutrients are proteins, carbohydrates, and lipids. It's important to maintain appropriate amounts of each to maintain bodily function, not developing deficiencies. They provide energy for all bodily functions. Carbs and fats provide energy and protein to support the immune system and build and repair tissue.
What are micronutrients?
Micronutrients are required only in small amounts, they are vitamins and minerals.
What are some important considerations in selecting carbohydrate sources
The relative salt, fat, and sugars in the carbohydrate sources, whole grains etc. Limit sugar intake, chose only natural sugars, fiber, legumes, chose whole foods, get 25 grams of fiber a day.
Why is calorie management important? How should calorie management be integrated into a fitness program

Question 7: ____________ are the major source of energy for the body. The brain requires this fuel source exclusively.
Question 8: True or False; Carbohydrates, protein and fat are all converted to body fat when calories needs are exceeded.
What can positively and negatively affect flexibility?
Age, previous injuries, and activity level can all negatively affect flexibility.
Definition of flexibility:
Flexibility is the normal extensibility of all soft tissue that allows the full range of motion of a joint. For extensibility there must be optimum muscular control throughout the entire range of motion (dynamic range of motion), combination of flexibility and the nervous system's ability to control the range of motion efficiently.
What are some risks associated with poor flexibility?
Muscles and ligaments are shortened due to inactivity and this decreases the body's ability to maintain proper posture, increases the risk for low back pain, join pain and the risk of injury in everyday activities
What are some different techniques for flexibility training? What are their benefits?
-Self myofascial release: focuses on neural syste, and the fascial system/fibrous tissue that surrounds and separates muscle tissue, it reduced pain from latent trigger points and is a method of self massage
-Static stretching: passively taking a muscle to the point of tension and holding it, elongates and relaxes the muscle improving joint range of motion, decreases the chance of injury, improves posture, improves function prior to activity
-Dynamic stretching: uses force production of a muscle and the body's momentum to take a joint through the full available range of motion, increases heart rate and respiration, increases tissue temperature, reduces tightness and improves performance, delivers oxygen to working muscles
-Yoga and Pilates: yoga is the practice of posture as exercise, good posture leads to proper muscle flexibility and full ranges of motion
Question 1:True or False; Ligaments can be overstretched leading to excessively loose joints increasing the risk of injury.
Question 3: Flexibility exercises have been prescribed to successfully decrease all of the following EXCEPT
Question 5: Which form of flexibility gently applies pressure with implements such as foam roll, to stimulate sensory receptors controlled by the nervous system causing the muscle to relax.
Question 6: Which form of stretching passively takes a muscle to the point of tension and holds the stretched position for a minimum of 20 to 30 seconds.

What is the main focus of stabilization training?
to increase the individual's ability to stabilize their joints, spine, and posture during activity, it provides stabilization as well as neuromuscular efficiency. Stability= core and balance.
What are the two methods to improve stability?
-core training: improving ability to properly activate core is vital to improving overall function, hips, pelvis, lower back
What is the difference between the stabilization and movement systems? Why is understanding this important?
Stabilization system ensures proper segmental stabilization of each vertebrae of the spring during exercise or activity. It's just the core and muscles close to the spine. Movement system is optimal force production, force reduction, comes after stabilization. They are the larger muscles on the outside that move. It is important to understand this difference to prevent injury and perform activities safely and effectively stabilizing before carrying out movement.
What is the cardiorespiratory/cardiovascular system?
the system provides the tissues of the body with oxygen, nutrients, protective agents, and a means to remove byproducts/waste.
What is the cardiorespiratory/cardiovascular system comprised of
the heart, blood, and blood vessels as well as respiratory pump (sternum, ribs, vertebrae, muscle), and respiratory passageways
Why is cardiorespiratory endurance considered the most important component of physical fitness and the best indicator of overall health?
it is necessary to sustain the energy requirements of a normal life and cr endurance helps maintain body weight. The more fit an individual is the more efficiently oxygen is spread to body, prevents disease
How is cardio intensity measured? Why is this important to designing a cardio program?
Cardio intensity is measured by heart rate or maximal oxygen consumption, also by perceived exertion/difficulty level, the step test. This is important because you must have a means by which you can measure progress.
Be familiar with the work-out zones and stages of exercise.
1: 65-75% of max heart rate, 9-11 difficulty, 2: 75-85%, 13 difficulty, 3: 85-90 or sometimes 100, perceived as 18.

What is strength, endurance, hypertrophy, etc?
Strength is the ability of the neuromuscular system to provide internal tension and exert force against external resistance.
Hypertrophy: increased muscle mass leads to increase in metabolic rate and ability to burn calories.
Endurance: ability for muscles to work for extended periods of time, important for athletes and for those seeking fat loss.
Maximal strength: the ability to lift heavy loads, not neccessarily with high reps
Power: the ability to generate force quickly
Correct progression for developing strength?
Develop stabilization (muscular edurance and core strength, neuromuscular control), then strength (enhancement, hypertrophy, maximal), then power. Ways to do this: change the exercises, amount of weight used, number of sets/repetitions, rest periods.
Why is strength training important to functional movement
Aerobic exercise improves cardiorespiratory fitness, but muscular strength is important for athletic performance and normal activities of daily life such as bending, turning, lifting. Important for overall health and wellbeing.
What are the 3 types of muscle contractions?
Concentric: acceleration, exerts more force than is being placed upon it, muscle shortening occurs while tension is developed to overcome resistance (ex: dumbell biceps curl)
Eccentrlc: deceleration, stabilization, exerts less force than is being placed upon it, muscle lengthening occurs, known as negative, (ex: downward phase of dumbell biceps curl)
Isometric: stabilization, contraction. exerts a force equal to the force placed upon it, considerable force generated without movement, no joint movement. (ex: pause between upward and downward parts of bicep curl)
What are some benefits of strength training
Also it improves bone density decreasing the risk for osteoporosis, decreases risk for diabetes, heart rate and blood pressure decrease, perform everyday activities more efficiently, alter body composition by encouraging weight loss via calorie expenditure, improve self-image, prevent injury by strengthening connective tissues, improves communication between nervous and muscular systems, improves force production, betters dynamic postural control.

Question 9: Strength training can improve performance in all of the following ways EXCEPT
Decreases joint range of motion
Question 10: Which of the following is the proper exercise progression with regards to resistance training exercises?
Stabilization → Strength→ Power
Stress is the body's mental, physical, emotional response to any situation that is new, frightening, threatening, or exciting and therefore disrupts the internal balance or equilibrium of the body. Managing stress is an important step towards behavioral change and improved quality of life. Stress undermines our ability to stay well and is linked to illness and increasing health care costs. It can be beneficial, providing motivation. Positive stress is known as eustress, and sometimes health increases with stress. The body responds to stress with a fight or flight response. The hypothalamus sends hormones via the adrenal glands. Excercise is crucial to controlling stress. Coping is the attempt to manage stress so that it does not define your life. To manage stress it's important to realize that perception is under your control. It can be managed with mind calming procedures, muscle calming procedures, etc (Biofeedback, Yoga, meditation, Visualization, autogenic inhibition).
Anorexia, Bulemia, Binge Eating: defined as eating large amounts of food twice a week in short periods of time, or grazing all day.
What are some reasons many people have trouble changing unhealthy lifestyle habits?
Procrastination (often due to a lack of motivation), Preconditioned Cultural Beliefs (we are products of our environments, culture and physical surroundings), Gratification (instant gratification), Risk Complacency (don't worry about the future, I'll cross that bridge when I come to it), Complexity (being overwhelmed by the requirements of daily life), Indifference and Helplessness (the belief that no matter our lifestyle habits, health is predetermined and out of individuals hands), Rationalization (arguing or believing that things are not that bad), Illusions of Invincibility (people who believe they are untouchable).
What are the 5 categories addressed in the process of willful change?
Once you've recognized that you have a problem, the five steps are 1. Stopping Negative Behavior, 2. Preventing Relapse of Negative Behavior, 3. Developing a positive Behavior, 4. Strengthening a Positive Behavior, and 5. Maintaining a Positive Behavior
