When you use it
Use this method when you need to find your heart rate, for example before and after exercise. It needs only a watch or phone timer and two fingers.
Watch out
Do not count the pulse with your thumb, because the artery in the thumb makes the count inaccurate. Use your pointer and middle fingers only.

When you use it
Use this rule when a question asks what happens to fitness gained through training after a student stops exercising.
Watch out
Fitness cannot be stored for later use. Any adaptation from training is reversed when training stops, which is called detraining, so a break in exercise undoes the gains.

10 multiple-choice questions written against this chapter, each with its answer and the reason. Try one before you open the answer.
Question 1
According to the World Health Organization, what is health?
Answer: B A state of complete physical, mental and social well-being
Why
The chapter says the World Health Organization defines health as a state of complete physical, mental and social well-being. It is not just the absence of disease.
Question 2
How many basic organ systems does the human body have, according to the chapter?
Answer: C Eleven
Why
The chapter states that the human body is made up of eleven (11) basic organ systems that manage all the essential body functions.
Question 3
Abel counts his radial pulse and feels 20 beats in 15 seconds. What is his heart rate in beats per minute?
Answer: B 80 bpm
Why
The chapter says to multiply the number of beats counted in 15 seconds by 4. So 20 × 4 = 80 bpm. The chapter gives this same example.
Question 4
Which of these is a health-related physical fitness component?
Answer: C Flexibility
Why
The health-related components are body composition, cardiorespiratory fitness, flexibility, muscular endurance and strength. Agility, balance and speed are skill-related components.
Question 5
A PE teacher in Addis Ababa explains the FITT principle. What does the letter I stand for?
Answer: B How hard the exercise is
Why
In FITT, F is frequency (how often), I is intensity (how hard), the second T is time or duration (how long), and the last T is type of activity.
Question 6
The target heart rate zone is between 50% and 85% of a person's maximum heart rate. Maximum heart rate is calculated as 220 minus age. What is the target heart rate zone for a 20-year-old student?
Answer: A 100 to 170 bpm
Why
Maximum heart rate = 220 − 20 = 200 bpm. 50% of 200 = 100 bpm. 85% of 200 = 170 bpm. So the zone is 100 to 170 bpm.
Question 7
Which change is an effect of regular aerobic exercise on the heart, according to the chapter?
Answer: C The resting heart rate is lowered to an average of 72 bpm
Why
The chapter says aerobic activities increase stroke volume (the amount of blood pumped per heartbeat) and lower your resting heart rate to an average of 72 bpm.
Question 8
In a concentric contraction, what happens to the muscle?
Answer: A It shortens and creates movement around a joint
Why
The chapter says concentric contraction is the most common form of muscular contraction. The muscle acts as a prime mover, shortens under tension and creates movement around a joint.
Question 9
Tigist holds a wall press for 10 seconds. Her muscle tension increases, but the muscle does not change length and no movement happens. What type of contraction is this?
Answer: D Isometric contraction
Why
In an isometric contraction, the muscle increases in tension but there is no change in its length and no movement. The chapter uses the wall press as its example of isometric contraction.
Question 10
Dawit, a footballer in Hawassa, wants to gain as much strength as possible in his legs. Which weight training program should he follow, according to the chapter?
Answer: B Low repetitions with high resistance
Why
The chapter says a weight training program using low repetitions and high resistance gives the greatest strength gains. High repetitions with low resistance give the greatest improvement in muscular endurance.
