📋 Key Definitions and Core Concepts

VO2 Max: The maximum volume of oxygen an individual can uptake, transport, and utilise per minute during maximal exercise.
Inverted-U Theory: Arousal theory stating performance increases with arousal up to an optimal midpoint, beyond which performance deteriorates.

🔍 Key Principles & Specification Requirements

  • Energy systems: ATP-PC (0-10s maximal, alactic), Glycolytic/Lactate (10-60s high intensity), Aerobic (submaximal long duration).
  • Biomechanics: projectile trajectory (angle, velocity, release height), Bernoulli principle and Magnus effect in ball spin.
  • Psychology: Catastrophe theory, Vealey's sport confidence, Bandura's self-efficacy, Weiner's attribution theory.

💡 Worked Example Question

Exam-Style Question

Question:

Explain how the Magnus effect causes a spinning football to swerve in flight.

Model Solution & Mark Scheme:

When a ball is kicked with topspin or sidespin, the spinning surface drags a boundary layer of air with it. On one side, airflow travels in the same direction as the spin, increasing local air velocity and reducing air pressure (Bernoulli's principle). On the opposite side, air opposes the spin, creating high pressure. The pressure differential creates a perpendicular Magnus force swerving the ball.
