proper warm-up.
proper warm-up and cool-down.
proper cool-down.
proper warm-up and stretching.

Explanation:

Injury prevention during vigorous activity requires preparing the body for exertion (warm-up) and aiding recovery post-activity (cool-down). Warm-ups increase blood flow and flexibility, while cool-downs reduce muscle soreness and prevent blood pooling. Stretching is often part of warm-up/cool-down, not a separate standalone step here.

Answer:

proper warm-up and cool-down.
