QCM : Fundamentals of Sports Materials and Performance — 8 questions

Question 1

1. What is polymerization?

The chemical reaction that bonds monomers together to form a polymer

The bond between two polymer chains that prevents remelting

The physical change that makes a plastic softer when heated

The process of breaking a polymer into smaller monomers

Explication

Polymerization is the chemical reaction that joins many monomers into a larger polymer. The other options describe different concepts, such as heating behavior or cross links.

Answer

The chemical reaction that bonds monomers together to form a polymer

Question 2

2. How do thermosoftening plastics behave when heated?

They become stronger only after repeated heating cycles

They soften, can be remoulded, and can be used again

They resist heat because they contain many cross links

They harden permanently and cannot be reshaped

Explication

Thermosoftening plastics have no cross links, so they melt and can be reshaped multiple times. Thermosetting plastics are the ones that harden permanently.

Answer

They soften, can be remoulded, and can be used again

Question 3

3. Which set contains the five essential nutrient groups named for an athlete's diet?

Proteins, fats, water, vitamins, and salt

Proteins, carbohydrates, water, minerals, and vitamins

Proteins, carbohydrates, fats, minerals, and vitamins

Carbohydrates, fats, fibre, minerals, and water

Explication

The five nutrient groups listed are proteins, carbohydrates, fats, minerals, and vitamins. Water is essential for hydration, but it is not one of the five groups in this list.

Answer

Proteins, carbohydrates, fats, minerals, and vitamins

Question 4

4. What best defines doping in sport?

Taking illegal substances to try to improve performance

Following a strict diet to increase energy intake

Training at a higher intensity than usual before competition

Using legal supplements to support recovery after training

Explication

Doping is defined as athletes taking illegal substances to improve performance. The other options may affect performance, but they are not doping.

Answer

Taking illegal substances to try to improve performance

Question 5

5. Which event is identified as the first ban on doping in the timeline?

The creation of the World Anti-Doping Agency after 1998

The first doping tests in cycling and football in 1966

The International Association of Athletics Federations banning doping in 1928

The major Tour de France scandal in 1998

Explication

The source states that the International Association of Athletics Federations first banned doping in 1928. WADA came later, after the 1998 scandal.

Answer

The International Association of Athletics Federations banning doping in 1928

Question 6

6. Which testing approach is described as the main method for detecting doping substances in urine samples?

Reaction time testing

X-ray imaging

Electrocardiography

Mass spectrometry

Explication

Most doping testing uses mass spectrometry on urine samples, where each substance has a unique chemical fingerprint. The other options are not the detection method described.

Answer

Mass spectrometry

Question 7

7. How can technology help coaches and support teams monitor athlete performance?

By guaranteeing that injuries will not happen during competition

By tracking fitness, technique, tactics, and recovery through data analysis

By removing the need for athletes to review their own performance

By replacing the need for any training plan or coaching decisions

Explication

Technology is used before, during, and after events to collect and analyse data for fitness, skills, injury prevention, and strategy. It supports decision-making rather than replacing training or eliminating injury risk.

Answer

By tracking fitness, technique, tactics, and recovery through data analysis

Question 8

8. What does a higher ISO setting do in sports photography?

Reduces camera shake by stabilizing the lens automatically

Freezes motion more sharply by shortening exposure time

Makes the image brighter but can increase noise or grain

Opens the lens wider to let in more light

Explication

ISO controls sensor sensitivity, so increasing it can brighten an image, but it often increases noise or grain. Shutter speed controls motion blur, while aperture controls how much light enters the camera.

Answer

Makes the image brighter but can increase noise or grain
