The correct answer is over 30%. This means that the prevalence of obesity among U.S. adults is greater than 30%. This suggests that a significant portion of the adult population in the U.S. is affected by obesity, which is a major health concern.

Anorexia is an eating disorder characterized by a preoccupation with body weight, leading to self-starvation. Individuals with anorexia often have a distorted body image and an intense fear of gaining weight. They restrict their food intake to an extreme degree, often resulting in severe weight loss and malnutrition. The disorder is driven by a desire for control and a sense of pride in achieving and maintaining a low body weight. This explanation aligns with the given answer, which is Anorexia.

Muscular strength and endurance are components of health-related physical fitness because they contribute to overall physical health and well-being. Muscular strength refers to the ability of muscles to exert force, while muscular endurance refers to the ability of muscles to sustain repeated contractions over a period of time. Both of these components are important for everyday activities and can help prevent injuries and improve overall physical performance. Agility and power, while important for certain sports or activities, are not specifically categorized as components of health-related physical fitness.

Obesity is linked to low levels of physical activity because when individuals engage in less physical activity, they burn fewer calories. This can lead to an imbalance between calorie intake and expenditure, resulting in weight gain. Regular physical activity helps to increase metabolism, burn calories, and maintain a healthy weight. Therefore, low levels of physical activity contribute to the development and progression of obesity.

Alcohol is not a risk factor for heart disease. While excessive alcohol consumption can lead to other health issues such as liver disease, it is not directly linked to heart disease. On the other hand, cholesterol, inactivity, and smoking are all well-known risk factors for heart disease. High cholesterol levels can lead to the buildup of plaque in the arteries, inactivity can contribute to weight gain and poor cardiovascular health, and smoking damages the blood vessels and increases the risk of heart disease.

High-density lipoprotein cholesterol (HDL) is the correct answer because it is known as the "good" cholesterol. HDL helps to remove excess cholesterol from the bloodstream and transport it back to the liver for disposal. This process prevents the buildup of cholesterol in the blood vessels, reducing the risk of blood vessel damage and progression of cardiovascular diseases. LDL cholesterol, on the other hand, is known as the "bad" cholesterol because it can contribute to the development of plaque in the arteries, leading to blood vessel damage. Total cholesterol and very low-density lipoprotein cholesterol (VLDL) are not specifically associated with protecting against blood vessel damage.

The proper term for a weight that can be lifted 10 times but not 11 times with the proper form is 10RM. RM stands for "repetition maximum" and indicates the maximum number of repetitions that can be performed with good form before reaching muscle failure. In this case, the individual can lift the weight for 10 repetitions, but their muscles fatigue and cannot complete an 11th repetition.

The correct answer is medical history review. This is because before conducting any fitness tests or assessments, it is important to review the exercise participant's medical history. This helps to identify any pre-existing health conditions, injuries, or other factors that may affect their ability to safely participate in the exercise program. By reviewing their medical history, potential risks can be identified and appropriate precautions can be taken to ensure the participant's safety during the exercise program.

The patient's medical provider should determine when a patient with heart disease can begin resistance training because they have the medical knowledge and expertise to assess the patient's condition and determine if it is safe for them to engage in such activities. They can take into account the patient's specific medical history, current medications, and overall health status to make an informed decision. This ensures that the patient's safety and well-being are prioritized during the exercise program.

The overhead press primarily strengthens the deltoids, which are the muscles responsible for lifting the arms overhead. This exercise specifically targets the anterior deltoids, medial deltoids, and posterior deltoids, helping to increase shoulder strength and stability. The bench press primarily targets the chest muscles, the dumbbell fly primarily targets the chest and shoulder muscles, and the dumbbell curl primarily targets the biceps. Therefore, the overhead press is the correct answer as it specifically focuses on strengthening the deltoids.

ACSM (American College of Sports Medicine) recommends that individuals engage in a minimum of 150 minutes of aerobic exercise each week. This recommendation is based on the health benefits associated with regular aerobic exercise, such as improved cardiovascular health, increased endurance, and weight management. Engaging in at least 150 minutes of aerobic exercise per week can help individuals meet the physical activity guidelines and maintain overall health and well-being.

Overtraining refers to excessive physical training without adequate rest and recovery. It can lead to various physical signs and symptoms. Decreased body weight can be associated with overtraining as intense exercise can lead to increased metabolism and calorie burn, resulting in weight loss. Loss of appetite can also occur due to hormonal imbalances and increased stress on the body. Muscle tenderness is a common sign of overtraining as excessive exercise can cause muscle damage and inflammation. Therefore, all of the above physical signs can be associated with overtraining.

An elevated resting blood pressure is primarily related to health. This means that having high blood pressure at rest is often a sign of an underlying health issue or condition. It can be caused by factors such as poor diet, lack of exercise, stress, obesity, smoking, or genetics. Monitoring and managing one's health is crucial in preventing and controlling high blood pressure to reduce the risk of developing more serious health problems like heart disease or stroke.

Before deciding if a participant requires a physician consent or referral to a clinic-based supervised exercise program, a fitness professional should consider the participant's health status, fitness test results, and desired level of physical activity. These factors are important in determining the participant's overall fitness level, any potential health risks or limitations, and the appropriate level of supervision and guidance needed during exercise. Considering all of these aspects ensures that the participant's safety and well-being are prioritized, and that they receive the most suitable exercise program for their individual needs.

Leg power, such as vertical jump, is primarily related to performance. This refers to an individual's ability to generate force and power in their legs, which is crucial for activities such as jumping, sprinting, and explosive movements. Leg power is often a key factor in sports performance, as it can enhance an athlete's speed, agility, and overall athletic ability. While leg power can also contribute to fitness and overall health, its primary association is with performance in physical activities.

A mesocycle refers to a phase of resistance training that typically lasts about 4-6 weeks. It is a periodized approach to training where specific goals and adaptations are targeted. Within a mesocycle, different training variables such as intensity, volume, and exercise selection may be manipulated to promote specific adaptations. The mesocycle is part of a larger training plan called a macrocycle, which encompasses multiple mesocycles and can last several months to a year. Therefore, the given correct answer, mesocycle, aligns with the description provided.

Regular, vigorous physical activity at the ACSM-recommended levels has been shown to have a positive effect on resting heart rate. The heart becomes more efficient at pumping blood, resulting in a decrease in resting heart rate. This is because regular exercise strengthens the heart muscle, allowing it to pump more blood with each beat. As a result, the heart doesn't have to work as hard at rest, leading to a decrease in resting heart rate.

Engaging in 20 weeks of regular, vigorous physical activity at the recommended levels by the American College of Sports Medicine (ACSM) can lead to a decrease in heart rate during a standard submaximal work task. This suggests that the conditioning program has improved cardiovascular fitness, allowing the heart to pump more efficiently and effectively. As a result, the heart does not need to work as hard to meet the demands of the submaximal task, leading to a decrease in heart rate.

Dietary records often show that individuals who are obese consume a higher percentage of fat compared to persons of normal weight. This means that obese individuals tend to have a higher intake of fat in their diet, which can contribute to weight gain and obesity. Fat is a concentrated source of calories, and consuming excess fat can lead to an imbalance in energy intake and expenditure, resulting in weight gain. Additionally, high intake of dietary fat can also lead to other health issues such as cardiovascular diseases.

The principle of overload states that in order to enhance muscular performance, the body must exercise at a level beyond that to which it is normally stressed. This means that in order to see improvements in strength and endurance, the muscles need to be challenged with progressively increasing levels of resistance or intensity. By continually pushing the body to work harder than it is accustomed to, it adapts and becomes stronger and more efficient. This principle is the foundation of resistance training and is essential for achieving fitness goals.

A range of RPE values from 12 to 16 is recommended in a training program to achieve cardiorespiratory fitness goals. This range indicates a moderate level of intensity during exercise, which is ideal for improving cardiovascular fitness. It allows individuals to challenge themselves without overexertion, ensuring that they can sustain the workout and gradually improve their fitness levels over time.

The AHA (American Heart Association) and ACSM (American College of Sports Medicine) recommend that individuals obtain physician consent before starting an exercise program if they have two or more primary risk factors for CHD (Coronary Heart Disease). This is because individuals with multiple risk factors are at a higher risk for developing CHD and may require medical supervision or further evaluation before starting an exercise program.

Receiving a certificate of achievement for walking the most miles in a month serves as a positive reinforcement for exercise behavior. This recognition and reward can motivate individuals to continue engaging in physical activity and strive to achieve their fitness goals. The certificate acknowledges their efforts and progress, boosting their self-esteem and sense of accomplishment. This positive reinforcement helps to reinforce the behavior of exercising and encourages individuals to maintain an active lifestyle.

The training age refers to the number of years a person has been engaged in a specific type of training. In this case, the 40-yr-old male has been resistance training since he was 35 yr old, which means he has been training for 5 years. Therefore, the correct answer is 5 yr.

The fitness professional should conduct periodic fitness retesting to assess any changes in the participant's health status over time. This helps to track progress and make necessary adjustments to their fitness program. Periodic readministration of a PAR-Q (Physical Activity Readiness Questionnaire) or an HSQ (Health Status Questionnaire) is important to update the participant's health information and identify any new health concerns or changes in their medical history. Participant monitoring during exercise ensures their safety and allows the fitness professional to observe any signs of discomfort or potential health issues during the workout. Therefore, all of the above actions are necessary to maintain current records of a participant's health status.

The ACSM recommends that apparently healthy adults should perform 8-10 exercises, with 1 set to fatigue, and 8-12 repetitions, on 2-3 nonconsecutive days a week. This volume and intensity of resistance training is considered appropriate for maintaining and improving muscular strength and endurance in this population.

Isometric is the term that best describes the type of muscular action in which the muscle length remains constant and no movement occurs. In isometric contractions, the muscle generates tension without changing length, resulting in static strength. This type of contraction is commonly used in exercises such as planks or wall sits, where the muscles are contracted without any visible movement. Isometric contractions are beneficial for building muscular strength and stability.

The training volume is calculated by multiplying the number of sets, reps, and weight lifted. In this case, the individual performed 3 sets of 8 reps with 100 lb on the bench press. So, the training volume would be 3 (sets) x 8 (reps) x 100 (lb) = 2400 lb.

Eccentric muscle actions are most likely to result in muscle soreness. This is because eccentric contractions involve the lengthening of the muscle while it is under tension, such as when lowering a weight during a bicep curl. This places greater stress on the muscle fibers, leading to microscopic damage and inflammation, which can result in soreness and stiffness. Concentric contractions, on the other hand, involve the shortening of the muscle while under tension, and do not typically cause as much muscle soreness. Isometric contractions involve holding a muscle in a static position, and isokinetic contractions involve maintaining a constant speed throughout the movement.

For enhancing local muscular endurance, shorter rest periods are recommended. Resting for 30-60 seconds between sets and exercises allows the muscles to partially recover while still maintaining a level of fatigue. This helps to improve the endurance capacity of the muscles by challenging them to sustain repeated contractions over an extended period. Longer rest periods would allow for more complete recovery, which is not the primary goal in this case.

Circuit training is most likely to result in gains in muscular strength and cardiorespiratory endurance. This is because circuit training involves performing a series of exercises in a sequence with minimal rest in between. This type of training combines both strength and cardiovascular exercises, allowing for an efficient and effective workout. By incorporating both types of exercises, circuit training helps to improve muscular strength and endurance simultaneously.

A dumbbell lunge involves performing a lunge exercise while holding dumbbells, which adds resistance to the movement. This type of training is known as dynamic constant external resistance training because the resistance remains constant throughout the exercise, regardless of the joint angle or muscle length. Isokinetic training involves maintaining a constant speed of movement, which is not the case in a dumbbell lunge. Isometric training involves holding a static position, while plyometric training focuses on explosive movements. Therefore, the correct answer is dynamic constant external resistance training.

The RM (repetition maximum) loads refer to the amount of weight lifted for a specific number of repetitions. In this question, the 3RM to 6RM range is the correct answer because it represents a higher intensity of weightlifting. When individuals lift heavier weights for fewer repetitions, it places a greater demand on their muscles, leading to increased muscular strength development. The other options (8RM to 10RM, 12RM to 15RM, and 18RM to 20RM) involve lifting lighter weights for more repetitions, which primarily focus on muscular endurance rather than strength.

ACSM (American College of Sports Medicine) recommends that weight loss should generally be limited to 1kg per week. This is because losing weight at a slower and more gradual pace is considered to be healthier and more sustainable. Rapid weight loss can often lead to muscle loss, nutrient deficiencies, and a decrease in metabolism. By aiming for a weight loss of 1kg per week, individuals can focus on making long-term lifestyle changes, such as incorporating regular exercise and adopting a balanced and nutritious diet, which are more likely to result in successful and lasting weight loss.

The correct answer is "all of the above" because according to ACSM's guidelines for Exercise Testing and Prescription, high-risk individuals are those with known cardiovascular diseases, moderate risk includes men over 45 years and women over 55 years with 2 or more risk factors, and low risk includes men over 45 years and women over 55 years who have no more than one risk factor. Therefore, all three categories are included in the answer.

The question is asking for the training principle that is not one of the general training principles. The general training principles include progression, overload, and specificity. The correct answer is "none of the above" because all of the options listed (progression, overload, specificity) are indeed general training principles.

The answer is 50% because it is the only option that represents a significant percentage of adults not meeting the recommendation for 30 minutes of moderate-intensity physical activity. The other options (10%, 30%, and 70%) represent lower or higher percentages, which would indicate a smaller or larger proportion of adults not meeting the recommendation. Therefore, the most reasonable answer is 50%.

For about 68% of individuals of the same age, the error (1 standard deviation) in estimating maximal heart rate is about 10 beats • min–1. This means that for the majority of individuals, the estimated maximal heart rate can deviate by approximately 10 beats per minute from the actual value.

The term that describes the time between the eccentric and concentric phases of a plyometric exercise is the amortization phase. This phase is also known as the transition phase, and it refers to the brief moment when the muscle switches from the eccentric (lengthening) phase to the concentric (shortening) phase. During this phase, the muscle undergoes a rapid change in direction, storing and releasing energy to produce a powerful and explosive movement. It is important to minimize the duration of the amortization phase to optimize the efficiency and effectiveness of the plyometric exercise.

Featuring Jerry's success in a newsletter or bulletin board fosters his sense of achievement, which can increase his motivation to continue regular exercise. By publicly acknowledging and celebrating his accomplishments, Jerry will feel a sense of pride and recognition, which can boost his self-esteem and motivation. This positive reinforcement can encourage him to continue his exercise routine and strive for further success.
