-Body composition

Accepted Answer

Percent body fat is a measure of body composition.

Answer: B
 Seventy percent water by weight is a characteristic of body composition.

Answer: C
 Skin-fold calipers are a tool used to assess body composition by measuring skin thickness at various sites on the body.

Answer: D
 Sixty percent of body weight is a characteristic of body composition, specifically referring to the percentage of body weight that is made up of muscle tissue.

Question 7

A person trying to gain lean body mass has:

Accepted Answer

To gain lean body mass, a person needs to consume a high protein diet and engage in strength training exercises. Adequate protein intake is essential for building and repairing muscle. Strength training stimulates muscle growth and helps to increase lean body mass. Increased fluid intake may be necessary to support the body's increased protein and energy needs during muscle building, but there is no specific need for decreased fat or electrolyte intake. The fitness needs may change, but the question asks for the best choice(s), and the answer is D.

Question 8

Which of the following reflects an improvement in cardiovascular health resulting from regular engagement in aerobic exercise?

Accepted Answer

Regular engagement in aerobic exercise can increase the levels of high-density lipoprotein cholesterol (HDL), which is considered good cholesterol that helps remove bad cholesterol from the arteries, leading to improvements in cardiovascular health.

Option A is incorrect because an increase in lean body mass is a reflection of strength training and not necessarily aerobic exercise.

Option C is incorrect because stress relief can be a benefit of both aerobic and non-aerobic exercise.

Option D is incorrect because improvements in sleep patterns can be attributed to various factors, including stress reduction, but not necessarily aerobic exercise.

Option E is incorrect because while regular exercise can reduce the risk of some types of cancer, it is not necessarily a reflection of improvements in cardiovascular health.

Question 9

Which of the following behavioral techniques supports healthy body weight changes?

Accepted Answer

Goal setting and a plan is a behavioral technique that supports healthy body weight changes because it provides a structured approach to weight loss that can help individuals stay motivated and on track.

Question 10

Which of the following is an attribute of a scientifically literate person?

Accepted Answer

Scientific literacy involves using evidence and understanding the natural world through science. Choice D is the only answer option that directly relates to using scientific evidence to understand the world.

Question 11

Which of the following is not a technique used to measure body composition?

Accepted Answer

Body mass index (BMI) is a measurement of body size based on height and weight. While it can be used to screen for overweight and obesity, it does not directly measure body composition. The other choices (skin-fold calipers, Bod Pod, hydrostatic weighing, and light absorption technique) are all techniques used to directly measure body composition.

-Essential body fat (male)

Accepted Answer

Essential body fat for males is typically around three percent of body weight.

-Nutrigenomics

Accepted Answer

Nutrigenomics is the study of how an individual's genetic makeup interacts with the nutrients in the foods they eat and how that interaction affects their health and disease susceptibility.

Answer: D
 A clinical trial is a research study that tests the safety and effectiveness of new medical treatments, drugs, or interventions in humans. Nutrigenomics researchers may conduct clinical trials to study how specific nutrients or dietary interventions affect gene expression and health outcomes.

Answer: B, C
 Neither "an increase in cell number" nor "a disease epidemic that began in the 20th century" are related to nutrigenomics.

-Hyperplasia
Answers:

Accepted Answer

Hyperplasia is defined as an increase in cell number.

Answer: A 
 Genetic make-up that influences disease susceptibility is a reference to a person's genetic predisposition to certain diseases or conditions.

Answer: C 
 A disease epidemic that began in the 20th century is not related to hyperplasia.

Answer: D 
 Clinical trial is a type of medical research study that involves testing new treatments or procedures on human subjects. It is not directly related to hyperplasia.

-Stored body fat

Accepted Answer

Stored body fat is generally estimated at about 3,500 Calories per pound, which is a measure of the energy stored in that fat, rather than a percentage of body weight.

Question 16

Which of the following does not contribute to the Calorie intake of a person?

Accepted Answer

Water does not have any caloric value, while protein, carbohydrates, fats, and alcohol all contribute to the caloric intake of a person.

Question 17

The purpose of a cool-down is to:

Accepted Answer

The purpose of a cool-down is to gradually bring the body back to its pre-exercise state. This includes slowing down the heart rate (A), decreasing core body temperature (B), and slowly constricting blood vessels (C). Additionally, the cool-down allows for the continuation of adequate blood flow to the brain and facilitates the removal of metabolic waste products from the muscles (D). Therefore, the best choice is E - all of the above.

Question 18

The purpose of the warm-up is to:

Accepted Answer

The warm-up serves multiple purposes such as slowly increasing the pulse rate to an aerobic level, facilitating vascular changes (splenic shunt) to accommodate aerobic exercise, gearing up the energy metabolism, increasing the elasticity of the muscle fibers, which helps to prevent muscle, tendon, ligament, and joint injuries, as well as improve muscle contraction and preserve muscle glycogen in addition to reducing the amount of lactic acid build-up in the muscles. Therefore, option E "All of the above" is the correct answer.

Question 19

-Essential body fat (female)

Accepted Answer

Essential body fat is a critical amount of fat necessary for the maintenance of life and reproductive functions. For females, this percentage is typically around 12% of body weight, reflecting the additional fat necessary for reproductive organ protection and hormonal function.
