Question 1

____ are intended to bring dietary supplement manufacturing standards more in line with pharmaceutical standards.
A) RDAs
B) AIs
C) EARs
D) GMPs

Accepted Answer

Good Manufacturing Practices (GMPs) are intended to bring dietary supplement manufacturing standards more in line with pharmaceutical standards, ensuring product quality and safety. RDAs, AIs, and EARs are nutrient recommendations for daily intake levels, not manufacturing standards.

Which type of athlete participates in sports to be physically active, to maintain a healthy lifestyle, and for enjoyment?
A) elite
B) collegiate
C) performance-focused recreational
D) recreational
Twenty sprint cyclists were randomly selected to be in a study designed to test the effectiveness of 12 weeks of creatine supplementation on performance. Ten cyclists received a creatine supplement for three months while the other ten received a placebo. The cyclists did not know which supplement they were taking, while the researcher did have this information.

Accepted Answer

Recreational athletes participate in sports primarily for enjoyment, physical activity, and maintaining a healthy lifestyle, rather than for competition or professional advancement.

Question 3

The Daily Value (DV) is an estimate of the amount needed each day based on a ____ calorie diet.
A) 1,500
B) 2,000
C) 2,500
D) 3,000

Accepted Answer

The Daily Value (DV) is based on a 2,000 calorie diet, which is the recommended daily intake for an average adult. Therefore, option B, 2,000 calories, is the correct answer.

Question 4

The term macronutrient frequently refers to ____.
A) any nutrient that provides energy
B) the eight key nutrients needed for good health
C) carbohydrates, proteins, and fats
D) vitamins and minerals

Accepted Answer

Macronutrients are nutrients that provide energy and are required in large amounts, including carbohydrates, proteins, and fats. Option A is too broad, as not all nutrients that provide energy are considered macronutrients. Option B is incorrect, as there are only six essential nutrients needed for good health. Option D is incorrect, as vitamins and minerals are considered micronutrients, which are required in smaller amounts.

Question 5

The FDA must prove that a supplement is unsafe or _______________ before it can be removed from the market.

Accepted Answer

The answer of The FDA must prove that a supplement...

Question 6

What are the weakest of all scientific findings?
A) case studies
B) epidemiological studies
C) correlational studies
D) experimental studies

Accepted Answer

Case studies usually involve a single individual or a small group of people, which limits their generalizability to larger populations. They are also subject to bias and may not be able to establish cause-and-effect relationships.

Answer: B) epidemiological studies  
 Although epidemiological studies can provide valuable information about the patterns and distribution of diseases and risk factors in populations, they cannot establish cause-and-effect relationships. They are also subject to confounding variables and bias.

Answer: C) correlational studies  
 Correlational studies show the relationship between two variables, but they cannot establish causation. They may also be subject to confounding variables and may not reflect the entire population.

Answer: None of the above studies are inherently weak 
 Each type of study has its own strengths and weaknesses and can provide valuable information when used appropriately. The strength of a study depends on its design, execution, and interpretation of results.

Question 7

An example of an electrolyte is ____.
A) linoleic acid
B) potassium
C) vitamin A
D) vitamin C

Accepted Answer

Electrolytes are substances that dissociate into ions when dissolved in water, and potassium is an ion that is commonly found in the body and is essential for normal cellular functions. Linoleic acid, vitamin A, and vitamin C are all important nutrients, but they do not dissociate into ions in water and therefore are not electrolytes.

Question 8

Training periodization ____.
A) is always the same to ensure consistency
B) involves changing the intensity, volume, and specificity of training to achieve specific goals
C) unplanned and very flexible
D) based on each athlete's aerobic capacity

Accepted Answer

Training periodization involves changing the intensity, volume, and specificity of training over time in order to achieve specific goals. This helps to prevent overtraining, promote recovery, and optimize performance. The other options are not accurate descriptions of periodization.

Question 9

The ability to perform endurance-type activities, determined by the heart's ability to provide a sufficient amount of oxygen-laden blood to exercising muscles and the ability of those muscles to take up and use the oxygen is _______________.

Accepted Answer

The answer of The ability to perform endurance-type activities, determined...

Question 10

General agreement among members of a group is known as ____.
A) causation
B) consensus
C) correlation
D) anecdotal evidence

Accepted Answer

General agreement among members of a group is known as consensus. Causation refers to the relationship between cause and effect, correlation refers to a statistical relationship between two variables, and anecdotal evidence is based on personal experiences or opinions rather than on facts or scientific analysis.

Question 11

Which certification requires a bachelor's degree in an allied health field, such as exercise physiology, physical therapy, or nursing?
A) registered dietitian (RD)
B) personal trainer
C) certified athletic trainer (ATC)
D) clinical exercise specialists

Question 13

Exercise physiology case best be described as ____.
A) the art and science of training
B) the clinical study of mental and physical fatigue
C) the science of the response and adaptation of bodily systems to the challenges imposed by movement
D) case study observations of acute and chronic exercise
Enter the appropriate word(s) to complete the statement.

Accepted Answer

Exercise physiology is the science of the response and adaptation of bodily systems to the challenges imposed by movement. It involves the study of acute and chronic exercise and how the body responds to different types of physical activity. It is not focused on the art of training or mental and physical fatigue specifically, although these may be factors that are studied within exercise physiology. Case studies may be used as a research method within exercise physiology but do not serve as a comprehensive definition of the field.

Question 14

An analysis of a person or a particular situation is known as a(n) ____ study.
A) case
B) epidemiological
C) experimental
D) mortality

Accepted Answer

A case study is an analysis of a person or a particular situation in detail. Epidemiological studies are used to investigate the spread and distribution of diseases within a population. Experimental studies involve testing a hypothesis and manipulating variables in a controlled setting. Mortality studies focus on death rates and causes of death in a population.

Question 20

Which substance is banned in many sports?
A) creatine
B) caffeine
C) omega-3 fatty acids
D) ephedrine

Accepted Answer

Ephedrine is a stimulant that can enhance endurance and concentration, but it can also have serious side effects, including heart palpitations, seizures, and even death. It is banned by many sports organizations, including the World Anti-Doping Agency. Creatine and caffeine are legal and common supplements in sports, while omega-3 fatty acids are not typically banned as they are a natural nutrient found in many foods.
