Question 1

Neka strained her calf muscle during her daily jog.Her injury is an example of a ________ injury.

Accepted Answer

Neka's injury was caused by repetitive strain on her calf muscle while jogging, which is a common cause of overuse injuries. Traumatic injuries are caused by sudden physical impact or and invasive injuries involve a break in the skin or a physical intrusion into the body.

Question 2

The "C" in the acronym RICE for injury treatment stands for ________________________.

Accepted Answer

The "C" in RICE stands for compression, which refers to applying pressure to the injured area to reduce swelling and pain.

Question 3

Shivering ceases when the body core temperature drops to between 32°C and 30°C because the body has ______________________.

Accepted Answer

Shivering is a mechanism the body uses to generate heat to maintain its core temperature. When the core temperature drops to a certain level, shivering ceases because the body has lost its ability to generate heat through this mechanism.

Question 4

Ralph has been working in his yard on a very hot summer day.He is experiencing nausea,headache,dizziness,faintness,and the chills.Ralph is suffering from _____________________.

Accepted Answer

Ralph is showing symptoms of heat exhaustion, which is a milder form of heat illness. Heat cramps are painful muscle spasms usually caused by excessive sweating, while heat stroke is a life-threatening condition in which the body's temperature regulation system fails completely. Heat fatigue is a general feeling of tiredness or lethargy caused by exposure to heat.

Question 5

Gary went snowshoeing and got lost overnight.He experienced a potentially fatal condition resulting from abnormally low body core temperature.This condition is called _______________.

Accepted Answer

Hypothermia is the condition in which the body loses heat faster than it can produce, leading to a dangerously low body core temperature. This condition can be fatal if not treated promptly.

Question 6

Melba just sprained her ankle playing basketball.How often should she ice her injury?

Accepted Answer

The best course of action for Melba's sprained ankle would be to ice it every hour for the first 24 hours, and then 20 minutes every hour for the following 24-72 hours. This will help reduce swelling and inflammation in the affected area. Option A may be too frequent and lead to tissue damage, while option B may not be enough to effectively manage the injury. Option D may not provide enough time for the ice to have an effect.

Question 7

Why is flexibility so important to physical fitness?

Accepted Answer

Flexibility improves the efficiency of movement, making physical activities easier and reducing the risk of injury. It also allows for a greater range of motion in joints and muscles, leading to better balance, coordination, and posture.

Question 8

Aaron recently moved to a hot climate.How long will it take him to acclimatize to the heat?

Accepted Answer

It generally takes 10-14 days for the body to acclimatize to a change in temperature or climate. During this time, the body undergoes various physiological changes to adapt to the new environmental conditions. However, it may vary depending on individual factors such as age, health, and physical activity level.

Question 9

Tara is a beginning tennis player.Recently,she has been experiencing pain in her elbow.What equipment problem is most likely causing her pain?

Accepted Answer

Excessive racquet string tension can cause an increased shock impact on the arm, leading to pain in the elbow. This is a common issue for tennis players and can be remedied by adjusting the string tension or using a different racquet.

Question 10

Benjamin is said to have great agility.This means that he ___________________________.

Accepted Answer

Agility refers to the ability to move quickly and easily with coordination and balance. Having great agility means that Benjamin can move with great speed and efficiency while changing direction.

Question 11

Sandra has been told by her coach that in order to significantly decrease her risk of cycling injuries,she needs to do which of the following?

Accepted Answer

Using the proper size of bicycle frame is important for avoiding cycling injuries. A bike that is too big or too small for the rider can cause joint pain and strain on the body. Wearing sunglasses, having heated handlebars, and having a water bottle holder installed on the bike may have other benefits, but they will not significantly decrease the risk of cycling injuries.

Question 12

Static stretching should not be performed immediately prior to an all-out performance such as sprinting because it ____________________________.

Accepted Answer

Static stretching before an all-out performance has been shown to decrease muscle strength and power and can increase the risk of injury. It also does not improve contractility or increase fuel availability for the muscle. It is better to perform a dynamic warm-up before sprinting to get the muscles ready for the activity.

Question 13

Which of the following best describes a way to prevent overuse injuries?

Accepted Answer

Varying your fitness activities throughout the week helps prevent overuse injuries by giving your body time to recover from each activity and avoiding repetitive stress on the same muscles and joints. Setting goals that are too high and avoiding activity for extended periods of time can actually increase the risk of injury.

Question 14

The key component to look for in a running shoe is ____________________________.

Accepted Answer

The key component to look for in a running shoe is a flexible, impact-absorbing midsole. This will provide cushioning and support, while allowing for natural foot movement. A rigid midsole or a polypropylene liner may cause discomfort and impede proper foot function. A flexible heel counter can also be beneficial, but is not the most important factor.

Question 15

Dry,hot and red skin and a very rapid heart rate are signs of what heat injury?

Accepted Answer

Dry, hot and red skin and a very rapid heart rate are signs of heat stroke, which is the most severe form of heat injury. Hypothermia is the condition of having an abnormally low body temperature, heat exhaustion is a heat-related illness that can occur after exposure to high temperatures and dehydration, and heat cramps are painful muscle contractions that can occur after physical activity in hot weather.

Question 16

Wyatt broke his leg during a hockey game.What type of injury is this?

Accepted Answer

A traumatic injury is one that occurs due to a sudden and forceful impact, such as a fall or collision. Wyatt's broken leg during a hockey game is a clear example of a traumatic injury. Overuse injuries (A) occur due to repetitive stress on a muscle or joint, while repetitive injuries (C) are caused by repeating the same motion over and over again. Invasive injuries (D) involve damage to tissue or organs caused by medical procedures or conditions such as surgery.

Question 17

Sasha has been told by his coach that cool-down after exercise is a great time to stretch and to increase flexibility.Stretching exercises should last for how many minutes?

Accepted Answer

According to the American Council on Exercise, stretching exercises during cool-down should last for 5-10 minutes to help increase flexibility and prevent injury.

Question 18

Which of the following best describes a muscle endurance training activity?

Accepted Answer

Muscle endurance training involves performing a higher number of repetitions at a lower percentage of 1 RM (maximum weight that can be lifted for one repetition). Out of the given options, 20 repetitions of leg curls at 60% of 1 RM would be the best choice for a muscle endurance training activity.

Question 19

Which of the following statements about runner's knee is true?

Accepted Answer

The main symptom of runner's knee is pain that is experienced when downward pressure is applied to the patella after the knee is straightened fully.

Answer: D
 Runner's knee involves abnormal movement of the feet while exercising.

A) is false as women are more commonly affected than men. 
C) is false as runners should avoid activities that put compressive forces on the patella.

Question 20

Lola wants to start a muscle endurance training program.What percentage of her 1 RM should she use for resistance?

Accepted Answer

For muscle endurance training, it is recommended to use a lower percentage of one's one-repetition maximum (1 RM), typically in the range of 50-60%. This allows for higher repetitions with lighter weights, focusing on endurance rather than maximal strength.
