On which underlying 'model' of propulsion generation would correct feedback of stoke technique information in front-crawl swimming be based?

Question

Quizplus · Accepted Answer

Option C suggests that the hands behave as hydrofoils, but the swimmer's body roll generates much of the observed sidewards movement. This is based on the concept of utilizing the body's rotational movement to increase propulsion. Therefore, correct feedback of stroke technique information in front-crawl swimming would be based on this underlying model. Options A and B are not relevant as they are based on different concepts of propulsion generation, and Option D is incorrect as it suggests that legs generate most propulsive force, which is not true in front-crawl swimming.
