KQ1
Name the longest bone in the human body.
Femur
Which energy system provides energy for a 100m sprint?
ATP-PC system
What are the three stages of skill acquisition?
Cognitive, Associative, Autonomous
What type of motivation involves participating because you enjoy the activity?
Intrinsic motivation
How many hearts does an octopus have?
Three
What type of muscle fibre is most suited to marathon running and why?
Type I (slow-twitch) fibres because they are fatigue-resistant and use oxygen efficiently.
What is the main fuel source for the aerobic energy system?
Carbohydrates and fats
Is a rugby league pass an open or closed skill?
Open skill
Give one example of an extrinsic motivator in sport.
Trophies, money, praise, scholarships, selection in a team.
Which country consumes the most chocolate per person each year?
Switzerland
Explain the difference between a concentric contraction and an eccentric contraction.
Concentric = muscle shortens while producing force. Eccentric = muscle lengthens while producing force.
Name two immediate physiological responses that occur during exercise.
Increased heart rate, ventilation rate, stroke volume, cardiac output, lactate production.
Why is distributed practice generally more effective than massed practice for beginners?
It provides rest periods, reduces fatigue and improves learning quality.
How can self-regulation improve sporting performance?
Helps athletes set goals, monitor behaviour, manage emotions and maintain consistency.
Which animal can sleep for up to 22 hours per day?
Koala
A student lands awkwardly from a rebound and falls. Explain how the skeletal, muscular and nervous systems work together to help them regain balance.
Bones and joints provide structure, muscles contract to stabilise the body, and the nervous system detects imbalance and sends signals to muscles to correct posture.
Explain why a marathon runner and a 100m sprinter would require different training programs and different nutritional strategies.
Marathon runners rely heavily on the aerobic system and require endurance-focused training and higher carbohydrate availability for long-duration exercise. Sprinters rely mainly on ATP-PC and anaerobic systems, requiring power and speed training with nutrition supporting explosive performance and recovery.
A beginner golfer continually slices the ball. What type of feedback would best help them improve and why?
Augmented knowledge of performance feedback because it provides information about technique and movement patterns.
Explain how belonging to a fitness community such as CrossFit or Parkrun may improve participation and performance.
Provides social support, accountability, group cohesion, motivation, competition and a sense of belonging.
A bolt of lightning is approximately five times hotter than what natural phenomenon?
The Sun
A rugby player tears their ACL. Which body systems are most directly involved in the injury and recovery process?
Skeletal, muscular and nervous systems.
A marathon runner "hits the wall" at 35km. Explain what has happened physiologically.
Glycogen stores are depleted, forcing greater reliance on fat metabolism, reducing ATP production rate and causing fatigue.
Name all three energy systems in order from fastest ATP production to slowest.
ATP-PC → Glycolytic (Lactic Acid) → Aerobic
