Question 1

Which statement about heat exhaustion is true?

Accepted Answer

Heat exhaustion is a mild form of heat-related illness that can occur after exposure to high temperatures and inadequate fluid intake. It is not the most serious heat-related illness, as heat stroke is considered a medical emergency. It can be treated if caught early, unlike heat stroke. Additionally, while heat exhaustion can be serious, it usually does not result in death.

Question 2

Breaking a leg during a football game is an example of which type of injury?

Accepted Answer

A traumatic injury is one caused by a sudden and violent force or impact, such as breaking a leg during a football game. Overuse injuries occur from repeated stress on a particular part of the body, while repetitive injuries involve performing the same motion over and over again. Stress-related injuries are caused by mental or emotional stress affecting the body.

Question 3

Which exercise technique involves working to slowly and gradually lengthen a muscle or group of muscles?

Accepted Answer

Static stretching involves holding a muscle or group of muscles in a stretched position for a period of time in order to gradually increase flexibility and range of motion.

Question 4

Good advice to someone who wants to exercise in hot weather would include all of the following EXCEPT

Accepted Answer

Restricting fluid intake before exercising in hot weather can increase the risk of dehydration and other heat-related illnesses. It is important to stay hydrated before, during, and after exercise in hot weather.

Question 5

A muscle's ability to perform contractions for a length of time is muscle

Accepted Answer

Endurance is the ability of a muscle to perform contractions for a length of time, while flexibility is the ability of a muscle to move through a range of motions, strength is the ability of a muscle to produce force, and extension refers to a joint movement that increases the angle between two bones.

Question 6

Which type of exercise is designed to increase the heart rate?

Accepted Answer

Aerobic exercise is designed to increase the heart rate by using large muscle groups and improving cardiovascular endurance. This type of exercise includes activities such as running, cycling, swimming, and dancing.

Question 7

Miranda plays on the lacrosse team and knows that increasing her aerobic capacity will help her on the field. To determine her current status, the team's trainer will conduct a test in which Miranda will run on a treadmill for a designated time while measurements are taken. What will the measure of her aerobic capacity show?

Accepted Answer

Aerobic capacity is the maximum amount of oxygen that a person can consume during exercise. During the test, the trainer will measure the volume of oxygen that Miranda's muscles are consuming while running on the treadmill, which will determine her aerobic capacity. Option B refers to respiratory rate, option C refers to heart rate, and option D refers to lung capacity, which are not directly related to aerobic capacity.

Question 8

A potentially fatal condition resulting from abnormally low body core temperature is called

Accepted Answer

Hypothermia occurs when the body loses heat faster than it can produce it, resulting in a dangerously low body temperature that can lead to organ failure and death if left untreated.

Question 9

The amount of force that a muscle can exert in one contraction is muscle

Accepted Answer

Strength refers to the amount of force that a muscle can exert in one contraction.

Question 10

General pain that occurs below the knee and above the ankle is called

Accepted Answer

Shin splints are a common overuse injury that causes pain in the lower leg, specifically below the knee and above the ankle. Shin splints can be caused by a variety of factors, including overtraining, improper footwear, and poor biomechanics.

Question 11

In resistance training, which of the following represents the amount of weight or resistance that can be moved only once?

Accepted Answer

One repetition maximum (1 RM) represents the maximum amount of weight or resistance that a person can lift or move only once. It is used to determine a person's strength level and to establish the intensity of resistance training programs.

Question 12

A sprained ankle should be iced

Accepted Answer

The best choice is to ice the sprained ankle for 20 minutes every hour for the first 24 to 72 hours. This helps to reduce swelling and inflammation. Icing the ankle every two hours for the first 24 hours, as in option A, may not be frequent enough to effectively reduce inflammation. Icing the ankle three times a day, as in option B, may not be enough to reduce swelling in the initial hours after the injury. Icing the ankle every hour for the first 24 hours, as in option D, may be too frequent and could potentially cause skin damage from prolonged exposure to ice.

Question 13

When you engage in an aerobic exercise, such as a Latin dance class, which measurement will you use to confirm that you are working at 70% to 90% of your maximal heart rate for improved cardiorespiratory fitness?

Accepted Answer

Target heart rate is the measurement used to confirm that you are working at 70% to 90% of your maximal heart rate for improved cardiorespiratory fitness. This can be calculated using the formula: (220 - age) x 0.70 for 70% or (220 - age) x 0.90 for 90%. By monitoring your heart rate during exercise and ensuring it falls within this range, you can optimize the effectiveness of your workout in terms of cardiovascular fitness.

Question 14

During aerobic exercise, when you need to check your pulse to determine your heart rate, where on the body are the arteries located that are best to use?

Accepted Answer

The carotid artery located on the side of the neck or the radial artery located inside the wrist are the best arteries to use when checking pulse during aerobic exercise.

Question 15

The amount of effort needed during a workout to improve some aspect of fitness is exercise

Accepted Answer

Intensity refers to the level of physical exertion required during a workout, which is necessary to improve aspects of fitness such as cardiovascular endurance, strength, and power. The greater the intensity, the greater the physiological adaptations that occur within the body.

Question 16

The relative proportions and distribution of fat and lean tissue throughout the body is its

Accepted Answer

The relative proportions and distribution of fat and lean tissue throughout the body is its composition.

Question 17

If a person working in his yard on a very hot summer day begins to experience nausea, headache, dizziness, faintness, and the chills, he could be suffering from

Accepted Answer

The symptoms described are indicative of heat exhaustion, which can occur when a person becomes dehydrated and overheated in hot weather. Heat cramps typically involve muscle cramps and spasms, while heatstroke is a more serious condition that can cause confusion, seizures, and loss of consciousness. Heat fatigue is a less specific term that may be used to describe general exhaustion or weakness caused by heat exposure.

Question 18

In hypothermia, death occurs when body core temperature drops to

Accepted Answer

Death from hypothermia typically occurs when the body core temperature drops to around 75-80°F (24-27°C), as the body's vital functions can no longer be sustained at such low temperatures.

Question 19

The range of motion that a joint or series of joints can achieve is

Accepted Answer

The range of motion refers to the degree to which a joint or series of joints can move in all directions. Flexibility is the ability to move a joint through a full range of motion, making it the best choice for this definition. Strength and endurance refer to the ability of muscles to produce force and sustain activity, respectively. Extension is a movement that increases the angle between two body parts, and while it can be related to range of motion, it is not the best choice for this definition.

Question 20

It is wise to deal with being outdoors in cold temperatures by

Accepted Answer

Wearing layered clothing allows for adjustments in insulation as needed and keeping hydrated helps to prevent dehydration, which can be a concern even in cold temperatures.
