○ proper posture
a
leverage
velocity overload
force application
10.
which involves physical activity that is competitive and follows well - established rules?
○ sport

Explanation:

Question 9

To determine the principle, analyze each option:

• Proper posture: Relates to body alignment, not foot push - off. Eliminate.
• Leverage: Involves using a lever (bones as levers) to optimize force. Pushing off ball or toes uses different lever arms, so leverage applies.
• Velocity overload: About increasing speed for adaptation, not foot push - off. Eliminate.
• Force application: Too general; leverage is a specific aspect of force application here. Leverage is more precise.

Analyze each option:

• Sport: Defined as competitive physical activity with established rules (e.g., soccer, basketball).
• Games: Can be non - physical or have less formal rules. Eliminate.
• Recreation: Focuses on enjoyment, not necessarily competitive or rule - bound. Eliminate.
• Tactics: Strategies, not the activity itself. Eliminate.

Answer:

B. leverage
