Question 1

Which of the following statements is false?

Accepted Answer

Fasting typically reduces the metabolic rate as the body adapts to conserve energy in response to a perceived shortage of food. This is a survival mechanism.

Question 2

Which of the following is a study design used in the field of nutrition science?

Accepted Answer

Intervention trials are commonly used in nutrition science to test the effectiveness of a particular diet or nutrient on a specific health outcome. The study involves randomly assigning participants into different groups, one of which receives the intervention and the other acts as a control group. The subjects are then followed up over time to assess the outcomes. Choice A (single-blinded conditions) and Choice C (repeated measures) are study designs that can be used in conjunction with an intervention trial, but they are not specific to nutrition science. Choice D (critical thinking) and E (data analysis) are not study designs.

Question 3

Which of the following medical conditions is associated with obesity?

Accepted Answer

Obesity is a major risk factor for a variety of medical conditions, including heart disease, cancer, type 2 diabetes, and hypertension. Therefore, all of the above options are associated with obesity.

Question 4

Recovery nutrition supports:

Accepted Answer

Recovery nutrition should support muscle glycogen repletion, muscle fiber repair, fluid and electrolyte repletion, and liver glycogen repletion. This is important for optimal recovery and preparation for future activity. Eating a combination of carbohydrates and protein within 30 minutes to an hour after exercise can help support these processes.

Question 5

-Improved fitness
Answers:

Accepted Answer

The overload principle is associated with improved fitness as it involves increasing the intensity, duration, or frequency of exercise to challenge the body and promote adaptation.

Question 6

-Flexibility exercise

Accepted Answer

Yoga is a form of exercise that focuses on flexibility and stretching.

Answer: A
 Jogging is a form of cardiovascular exercise that improves overall health and fitness, but may not specifically address flexibility.

Answer: B
 Weight lifting is a form of resistance training that can improve strength and muscle tone, but does not typically involve much stretching or flexibility work.

Answer: C
 70 to 85% of MHR (maximum heart rate) is a guideline for aerobic exercise intensity, but does not specifically address flexibility.

Question 7

A warm-up would help enhance LeBron's play and reduce his risk for injury.

Accepted Answer

A proper warm-up routine can increase blood flow to the muscles, improve flexibility and range of motion, and prepare the body for the physical demands of intense exercise, which can help enhance performance and reduce the risk of injury.

Question 8

The Bod Pod is an accurate method of determining LeBron's body fat percentage.

Accepted Answer

The Bod Pod is considered one of the most accurate methods for measuring body composition, including body fat percentage. Therefore, it can be used to determine LeBron's body fat percentage with a high level of accuracy.

Question 9

Which of the following contributes to the highest percentage of energy expenditure?

Accepted Answer

Resting energy expenditure (REE) contributes to the highest percentage of total daily energy expenditure, accounting for about 60-75% of the total energy expenditure in a sedentary individual. It represents the energy required for maintaining basic physiological functions such as breathing, circulation, and cellular metabolism while at rest.

Question 10

Which of the following systems is most affected by dehydration?

Accepted Answer

The cardiovascular system is most affected by dehydration because when a person is dehydrated, the volume of blood decreases, and the blood becomes thicker, making it harder for it to flow through the blood vessels, which can lead to increased heart rate and decreased blood pressure. Severe dehydration can even lead to cardiovascular collapse. While dehydration can also affect the other systems listed, the cardiovascular system is most immediately and dramatically impacted.

Question 11

Which energy-producing nutrient should LeBron make an effort to consume with carbs after a workout?

Accepted Answer

Protein is the best choice for LeBron to consume with carbs after a workout because it helps to repair and rebuild the muscles that were broken down during exercise. While linoleic acid and alpha-linolenic acid are essential fatty acids, they do not provide energy in the same way that carbs and protein do. Alcohol should be avoided after a workout as it can interfere with muscle recovery and hydration. MCT oils may be beneficial for energy, but they are not as important as protein for muscle recovery.

Question 12

The information source LeBron used to validate the "Go Max" goo was scientifically sound.

Accepted Answer

The statement doesn't provide any information about the scientific soundness of the information source LeBron used to validate the "Go Max" goo. Therefore, we cannot determine whether it was scientifically sound or not.

-Safe aerobic training zone
Answers:

Accepted Answer

The safe aerobic training zone is typically defined as exercising at 70 to 85% of your maximum heart rate (MHR).

Answer: A, D (optional)
 Jogging and yoga are examples of aerobic activities that can be done in the safe aerobic training zone. Weight lifting is not an aerobic activity and therefore is not associated with the safe aerobic training zone.

Question 15

LeBron's body composition is consistent with being physically fit.

Accepted Answer

LeBron's dedication to fitness and his rigorous training regimen help maintain his overall physical health, which is reflected in his body composition.

Question 16

Volleyball is an anaerobic activity.

Accepted Answer

Volleyball is considered an anaerobic activity because it involves short bursts of high intensity movements with small recovery periods. This type of activity relies on the body's stored energy sources rather than oxygen for fuel.

Question 17

The "Go Max" goo provides LeBron with 1.5 grams carbohydrate per kilogram body weight.

Accepted Answer

The statement does not provide enough information to determine the exact amount of carbohydrate "Go Max" goo provides per kilogram of body weight, as it does not specify the serving size or the carbohydrate content per serving.

-Strength gain load

Accepted Answer

80% of 1-rep-max is typically associated with strength gain load as it is a higher intensity that promotes muscle strength development.

Question 19

The component(s)of a total fitness program include:

Accepted Answer

A total fitness program should include all of the mentioned components - cardiovascular exercise for endurance and heart health, muscular endurance and strength for overall strength and function, and flexibility for mobility and injury prevention. Leaving out any of these components could lead to an imbalance in fitness and potential health issues.

-Muscular endurance development

Accepted Answer

The 60% of 1-rep-max is a common percentage used to develop muscular endurance, as it allows for higher reps and sets without causing excessive fatigue.

Answer: A
 The overload principle is an important concept in muscular endurance development, as it involves gradually increasing the intensity or volume of exercises in order to continually challenge the muscles and promote improvement.

Answer: B
 Antagonistic muscle exercises involve targeting opposing muscle groups in order to balance strength and prevent injury. This can also help with muscular endurance development, as it allows for rest periods between exercises targeting the same muscle group.

Answer: D
 While 80% of 1-rep-max is generally considered more suitable for strength training, it can also be used for muscular endurance development through high-intensity interval training or other similar techniques.
