Can it be said that swimming is the most mentally demanding of the three sports, and therefore, the most mentally relaxing once the individual adapts, whereas cycling and running may be more physically demanding but easier on the mind.
Is it true that the repetitive motion of cycling or running can lead to a form of meditation, but one that is not as intense as the mental focus required in swimming?
Does the fact that swimming requires a greater variety of movements and engagement of multiple muscle groups at once make it more mentally stimulating and exhausting, thus providing a deeper sense of relaxation afterwards?
Is the mental relaxation achieved through cycling or running more of a distraction from daily stress, whereas the mental relaxation achieved through swimming is more of a release of stress?
