Most strokes involve rhythmic and coordinated movements of all major body parts — torso, arms, legs, hands, feet, and head.
Within a competitive sense particularly, swim stroke techniques are continuously changing to become either easier or more efficient as more people explore the activity.
A study done by Rejman Marek called Goggle-free swimming as autonomous water competence from the perspective of breath control on execution of a given distance.
The study explored adolescents’ ability to maintain breathing rhythm while swimming with and without goggles, emphasizing water competence over stroke techniques.
Results showed that the absence of goggles negatively impacted breath control for both genders, with boys struggling more to swim effectively and safely.
