FITNESS COMPONENTS
Name the three of the five health-related fitness components.
Cardiovascular endurance, muscular strength, muscular endurance, flexibility, and body composition.
What happens to heart rate when exercise becomes more demanding?
It rises so more blood can circulate.
Give one thing a person should check before activity.
Accept: activity demands, readiness, equipment, environment, footwear, intensity, etc.
What tissue is injured in a sprain?
A ligament
What does the F in FITT mean?
Frequency — how often the activity happens.
A student can repeat a moderate resistance movement many times but cannot produce a large force once. Which component is stronger?
Muscular endurance.
Why does breathing become faster and deeper during activity?
To bring in more oxygen and remove more carbon dioxide.
What is the packet's simple warm-up rule?
Start easy, move gradually, and become more specific to the activity.
What tissue is injured in a strain?
A muscle or tendon.
What does intensity describe?
How hard the body is working.
Why is body composition not enough by itself to judge overall fitness
It is only one fitness component and does not measure all health, effort, skill, or ability.
What three structures/systems work together when a skeletal muscle pulls a bone and movement is adjusted?
Muscular system, skeletal system, and nervous system.
Why can fatigue become a safety problem late in activity?
Reaction time and technique can decline, reducing control.
What is the difference between a fracture and a dislocation?
A fracture is a break/crack in bone; a dislocation is bones at a joint forced out of normal position.
A beginner doubles time, frequency, and intensity in one week. What planning mistake is being made?
Changing too much at once instead of increasing one part gradually.
A student wants better flexibility. According to the packet, why is 'more range' not always better?
Useful flexibility is appropriate, controlled range for the person and activity; uncontrolled or painful range is not the goal.
Why can sensory information improve movement control?
Answer: It helps the nervous system adjust balance, position, speed, and force.
A player has correct equipment but the floor is wet. Why is the activity still unsafe?
Equipment does not remove environmental risk; the plan must change when the setting changes.
A student is dizzy and confused after a head impact but never blacked out. Why must this still be taken seriously?
Loss of consciousness is not required for a concussion; symptoms should be reported and evaluated.
Why is recovery not a sign that a fitness plan failed?
Recovery supports readiness, tissue repair, consistency, and safe progress.
Create a two-part example showing the difference between muscular strength and muscular endurance using the same muscle group.
Accept answers that correctly contrast producing greater force with repeating/sustaining force over time.
Explain the chain from lungs to muscles during sustained activity.
Lungs bring in oxygen; blood carries it; the heart pumps oxygen-rich blood to working muscles while wastes such as carbon dioxide are carried away.
A tired student slept poorly and is learning a new skill. Give two packet-based changes that could reduce risk.
Accept: lower intensity, practice a simpler version, take breaks, improve supervision/space, postpone until conditions/readiness improve.
Pain returns every practice after a rapid training increase. Name the likely injury pattern and two causes from the packet.
Overuse; causes can include repeated stress, rapid increases, repeated movement, poor technique, or insufficient rest
A student plans a long maximum-effort outdoor workout on a very hot day. Give four packet-based changes that would make the plan safer.
hydrate, change timing, use shade/breaks, reduce intensity, shorten time, move indoors, use appropriate equipment, monitor warning signs.
