Which environmental factor is NOT listed as influencing injury risk?

• A. Lighting
• B. Surface conditions
• C. Temperature
• D. Humidity

Answer: (A)

Injury risk in sport is shaped by environmental conditions that directly affect how the body performs and loads tissues. Surface conditions matter because traction and footing determine the likelihood of slips or sprains. Temperature changes how muscles and tendons behave—cold can reduce elasticity and increase stiffness, while heat elevates fatigue and risk of heat-related issues. Humidity influences how the body handles heat and sweat, affecting comfort and performance under stress.

Lighting, while important for visibility and safe navigation, isn’t listed here as an environmental factor that directly increases injury risk in this context. The other three are the factors typically cited for their direct physical or physiological impact, so lighting is the one not listed.
