Final answer:
The observation about players preferring sticks with a low lie when they skate crouched is related to sports science in the Health category, as it involves the ergonomic and performance aspects of the hockey stick in use.
Step-by-step explanation:
The observation that players who skate in a crouched position prefer sticks with a low lie is related to sports science, which falls under the broader category of Health. When a player is crouched, the angle between the stick and the ice surface decreases, making a low-lie stick more suitable as it keeps the blade flat on the ice. This affects both the player's comfort and the performance of the stick during a hockey game.
