Does creatine supplementation increase muscle size and strength?
Creatine (Cr) is an important energy source. Phosphorylated creatine (PCr) is an immediate source to replenish ATP. You need about 2 grams of Cr in your diet per day to maintain normal levels. Research shows that supplementation can prevent depletion and may, in some people, increase the amount stored by the body. PCr may increase the amount of work done in repeated, short duration, maximal work bouts. Supplementation may produce side effects (stomach pain, nausea, diarrhea, muscle cramping).
Social Wellness

What are training techniques for cardiorespiratory endurance?
Endurance training = any type of exercise aimed at improving cardiorespiratory endurance (most common type is continuous activity). Cross training: Alternate multiple training modes; May reduce boredom in training sessions; May reduce risk of overuse injuries; Improves overall cardiorespiratory endurance, not training specificity; Some people enjoy increased variety. Interval training: Often used by athletes and others who are at a higher fitness level; Uses repeated sessions (intervals) of higher-intensity exercises alternated with lower-intensity exercises; May be used to spur gains in intensity during improvement phase; Should not be done on a daily basis.
Explain how ATP is used for energy during exercise and identify the energy systems involved in the production of ATP for muscular contraction.
Energy: The fuel needed for muscle motion; Derived from the breakdown of food. Energy released from the breakdown of food creates a compound called ATP (adenosine triphosphate). ATP is made and stored in small amounts in muscle and other cells. The breakdown of ATP releases energy in a form that muscles can use for movement. It is the only compound in the body that can provide this immediate source of energy; therefore, ATP must be available for muscles in order for them to contract.
Discuss the strategies tactics that are effective for maintaining motivation for change and eliminating barriers to change.
Examining the benefits of behavior change and increasing self-efficacy can help you stay motivated for behavior change. Visualization, positive self-talk, positive role models, and social support are factors that contribute to increasing self-efficacy. Six common barriers to change are lack of knowledge, lack of motivation, denial, perceived invulnerability, low self-efficacy, and lack of social support. Identifying and eliminating barriers is key to successful change.

What are some responses to exercise?
Heart rate and stroke volume increase, resulting in increased cardiac output Arteries dilate, or expand Breathing rate increases
What is HIIT and results from recent discoveries?
High-Intensity Interval Training Results in both cardiovascular and skeletal muscle adaptations; Results in aerobic metabolic changes; Can safely be incorporated into the exercise routine of most individuals.
Muscular Strength
How much force a muscle (or muscle group) generates during a single maximal contraction. Allows optimal functioning in everyday tasks.
Discuss the general principles for developing a strength and endurance training program.
In the context of strength and endurance training, the progressive overload principle means that you need to progressively increase the amount of resistance with which you train. The intensity of training determines whether you primarily increase muscular strength or endurance. High-intensity training will increase muscular strength and size; low-intensity training will increase muscular endurance.

Phases in developing an individualized exercise program
Initial Conditioning Improvement Maintenance
Overload Principle
Is a key component of all conditioning programs: To improve fitness, the muscular and cardiorespiratory systems of the body must be stressed. Is achieved by increasing: Intensity of exercise (such as using heavier weights) and Time (duration) of exercise. Examples of this via duration include: Working a muscle longer by increasing the number of repetitions and Holding a stretch for a longer period of time, or stretching the muscle to a longer length. It does not mean engaging in painful or exhausting workouts.
What are the muscle exercise classifications?
Isometric Concentric Eccentric
What are the skeletal muscle exercise classifications?
Isotonic Isometric Isokinetic
What is the cardiorespiratory system?
It is made up of the following two systems: The cardiovascular system (the heart and blood vessels); The respiratory system (the lungs and muscles involved in respiration). Together, these systems deliver oxygen and nutrients throughout the body, and remove waste products from tissues. Exercise challenges the cardiorespiratory system by increasing the demand for oxygen and nutrients in working muscles.
List the four major barriers to physical activity and describe strategies that can be used to overcome each barrier.
Lack of time: Schedule a time to exercise for at least 30 minutes to a hour. Social and environmental influences: Have someone to go to the gym with. Inadequate resources: Go to a personal trainer to find the right exercise prescription for you. Lack of motivation/commitment: Having someone to go with you to the gym will help you stay motivated to go. Only 20% of adults in the US meet the required physical activity guidelines to achieve the threshold for health benefits.
Initial Conditioning Phase
Lasts roughly 2-6 weeks, depending on your initial fitness level. Start at a comfortable intensity level. Increase duration or intensity gradually (separately, not both at once). Goal of 20 to 30 minutes of low to moderate (40-60% H R R) activity by end of the phase. Be aware of body pains, and rest as needed.
Explain the benefits of developing cardiorespiratory fitness.
Lower risk of cardiovascular disease (C V D) Increased longevity Reduced risk of type 2 diabetes Lower blood pressure Increased bone density in weight-bearing bones Improved self-esteem and body image Improved muscle tone and easier weight control Improved sleep quality Increased energy Regular exercise is needed to improve your cardiorespiratory endurance.
Workout (Primary Conditioning Period)
Major components are frequency, intensity, time/duration, and type/mode of exercise. Known as the FITT principle. Methods of measurement include heart rate, counting repetitions to fatigue, or degree of tension in a stretch. Does not include warm-up or cool-down. 20-30 minutes per exercise session (at 3+ sessions per week) is minimum time required to improve fitness.
What are the variations in muscle fiber types?
Most people have roughly equal numbers of all three types Elite endurance runners/marathoners have more slow-twitch fibers Elite speed runners/sprinters have more fast-twitch fibers There is a possible genetic link between a predominance of fast-twitch fibers and certain diseases, such as obesity and diabetes Research indicates fibers might be able to convert from one type to another through training Fiber recruitment: process involving more muscle fibers to increase muscle force
What are the objectives of Healthy People 2020?
Reduce the proportion of adults who engage in no leisure-time activity. Reduce the death rates due to breast cancer, prostate cancer, and melanoma. Increase the proportion of physician office visits that include counseling or education related to nutrition or weight.

Increase the proportion of adults who get sufficient sleep.
Emotional Stability
Refers to how well you deal with day-to-day stressors.
Body Composition
Relative amounts of fat and lean tissue in your body. High percentage of body fat (obesity) is associated with: Increased risk of developing CVD; Type 2 diabetes; Some cancers; Regular exercise is an important factor in promoting loss of body fat and maintaining a healthy body weight.
Discuss the roles and adaptations of the cardiovascular and respiratory systems during exercise and training and identify the major changes that occur in skeletal muscles and the cardiorespiratory system in response to aerobic training.
Responses to exercise: Short-term changes that occur during and immediately after exercise. Include increases heart rate, stroke volume, cardiac output, and breathing rate. Adaptations to exercise: Changes over time that accrue with regular exercise. Include decrease resting heart rate, increased stroke volume, improved body composition.
What are some adaptations to exercise?
Resting heart rate decreases Maximum stroke volume increases VO2 max increases Respiratory muscle endurance improves Muscles' capacity to produce aerobic energy increases Adaptations are lost/reversed if exercise is stopped for an extended period
Intermediate Fibers (Type IIA)
Serve as a combination of the other two types Contract rapidly, produce great force, and resist fatigue
How do you design your aerobic exercise program?
Set goals (short-term and long-term). Warm-up (5-10 minutes of low-intensity exercise). Workout (F I T T principle): Frequency (e.g., 3-5 times per week); Intensity (e.g., 50-85% of maximal heart rate): Training threshold, Target heart rate (THR), Heart rate reserve (HRR), and Borg Rating of Perceived Exertion (R P E); Time/duration (e.g., 20-60 minutes per session); Type/mode of exercise (e.g., jogging, cycling, rowing). Cool-down (light exercise and stretching).
What are the keys to have a successful behavior change?
Setting Specific and appropriate goals. Documenting these goals in a behavior change. Creating a specific plan of action. Monitoring your progress toward each goal. Creating a plan to deal with challenges and relapses. Establishing meaningful rewards for achieving your goals.
What are the skeletal muscle fiber types?
Slow Twitch Fibers Fast Twitch Fibers Intermediate Fibers
Maintenance Phase of Muscular Strength and Endurance
Starts around week 20 Requires a long-term commitment to maintain gains The effort needed to maintain gains is not as great as the initial effort As little as one workout a week can maintain strength
Principle of Specificity
States that exercise training effect is specific to those muscles involved in the activity. Explains the importance of varied exercises for overall fitness improvement. Also applies to the types of adaptations that occur in the muscle. For example, strength training will not greatly improve muscular endurance.
What can anabolic steroid use do?
Synthetic forms of hormone testosterone. Serious side effects which can be lethal: Liver cancer, High blood pressure, Increased levels of "bad" cholesterol, Severe depression, Prostate cancer. Chemical precursors (androstenedione, D H E A, etc.) do not significantly increase strength or lean body mass.
Healthy People 2020
The current set of goals aimed at attaining high-quality, longer lives reducing the risk of injury and premature death.
Motivation
The drive that provides direction and gives you the persistence to achieve your goals.
What are types/modes of weight training programs?
The greatest strength gains are made with a training program using low repetitions and high resistance, while the greatest improvements in endurance are made using high repetitions and low resistance. Isotonic programs include exercises with movable loads. Isometric training includes exercises in which a muscle contracts at a fixed angle against an immovable object. Isokinetic exercises involve machines that govern the speed of movement during muscle contraction.
Name the major components of the cardiorespiratory system and describe their functions.
The heart: Right side = pulmonary circuit; Left side = systemic circuit. Blood vessels: Arteries, veins, and capillaries. The lungs: During exhalation, carbon dioxide is released into the air. During inhalation, oxygen is brought into the lungs, where it enters alveoli (tiny air sacs), and then passes into capillaries. Sends oxygen-rich blood back to the left side of the heart to start the process over again.
Describe the basic anatomy and physiology of muscle.
There are about 600 skeletal muscles in the body. Primary functions: provide force for movement, maintain posture and regulate body temperature. Muscle shortening or lengthening during a muscle action is what causes the body to move. Muscle function: Motor Unit—motor nerves and muscle fibers it controls. Various Sizes: A motor nerve can innervate a few muscle fibers for fine motor control; A motor nerve can innervate many muscle fibers for gross motor movement.
How much exercise is enough?
Threshold (minimum level) for health benefits: 30-60 minutes of moderate to high intensity exercise performed 3-5 days per week will likely achieve health benefits and reduce all causes of death. The U.S. government recommends at least 150 minutes of moderate-intensity exercise (or 75 minutes of vigorous exercise) per week for adults ages 18-64 years. The activity time can be divided into smaller segments throughout the day. Note this exercise dose may not prevent weight gain; longer workouts are likely to achieve additional benefits.
Explain the process of behavior change and describe the six phases that are part of the stages of change model.
To change a behavior, you must first recognize that the behavior is unhealthy and that you can make changes. Precontemplation Contemplation Preparation Maintenance Termination Assessing your current lifestyle and habits is an important first step in changing unhealthy behaviors.
How do you stay motivated during cardiorespiratory endurance exercise program?
To maintain your motivation for strength fitness, make it fun (facility and equipment must be encouraging), design a good routine (it must be realistic-not to hard or too easy), and find a compatible training partner (one that helps with lifts and provide verbal encouragement). Don't get discouraged by initial aches or pains; they will lessen over time and you will begin to feel and look better.
What are safety concerns in weight training program design?
Use spotters Use collars on the ends of free weight bars Don't drop weights Always warm up Breathe during exercises Use slow movements Maintain stability of core muscles, spine Start with light weights and work up gradually
Maintenance Phase
Usually reached after 16-28 weeks of training. Fitness goal has been achieved Continue exercising regularly, but no need to continue increasing duration, frequency, and intensity. Key factor in maintaining cardiorespiratory fitness is exercise intensity.
What is Borg's rating of perceived exertion?
When estimating R P E, consider overall effort: Breathing rate; Amount of sweating; Muscle fatigue. 15-point scale, ranging from 6 to 20: 6 on the scale means that there is no level of exertion; 8-11 on the scale is common during the warm-up or cool-down phase of the workout; 12-16 on the scale will correspond with the target heart rate range for most people.
