Breaststroke (BR)
INTRODUCTIONBreaststroke is a method of traveling through the water in a prone position and is considered a survival stroke. It is characterized by the use of symmetrical arm actions and symmetrical leg actions which, when coordinated, alternate between a propulsive phase and a gliding phase. Becoming proficient at Breaststroke develops Propulsion Competency and contributes to the development of Breath Control Competency.
Swimming on the front, compared to swimming on the back, allows better visibility to avoid hazards, determine one’s bearings, and orient to safe locations. Swim strokes that utilize symmetrical arm and leg actions tend to have glide phases and relatively slower stroke tempos, which often result in lower intensity and energy conscious methods of propulsion. Breaststroke in particular provides the best forward visibility of the front swim skills. Additionally, the coordination of the limbs and the timing between the distinct propulsive phase and glide phrase can be adapted to best serve a wide variety of use-cases and situations. For example, Breaststroke can be optimized for greater speed, such as for a competitive stroke; however, this is at the cost of higher energy expenditure and reduced visibility. Inversely, by elongating the glide it can be performed in a way that is relatively less strenuous, which is beneficial for long duration swims or can be used to recuperate between higher intensity swims, but at the cost of speed and efficiency.
When first learning Breaststroke, individuals should focus on developing a basic proficiency with the arm strokes and the kicks individually, before attempting to coordinate the actions as a whole stroke. Additional emphasis may need to be placed on learning the kick, as flexing the feet before extending the legs is unique and does not mimic any land-based movement or activity. As individuals become more comfortable with the symmetrical arm and leg cycles the focus should shift to coordinating the actions of the limbs in order to align the propulsive phases of the arms and legs and provide a glide phase, as well as provide efficient and consistent breathing. As proficiency increases, learning to modify the arms, legs, and timing for different situations should be emphasized, as well as building endurance and the ability to continue propelling for long durations.
The Breaststroke is defined as the following:
Body
Body positioned on front
Shoulders at or near surface
Head, neck, and spine in line
Arms
Arms move symmetrically
Stroke Cycle
Start with arms straight and overhead, at or just under surface
Press arms out until hands just past shoulder width
Bend elbows as hands pull towards chest
Bring hands together and finish pull with hands in front of the chest
Return arms to straight overhead position
Legs
Legs move symmetrically
Kick Cycle
Start with legs straight, together, and toes pointed
Bend hips and knees to bring heels towards hips with knees slightly separated
Flex ankles and turn toes out
Extend hips and knees to press legs backward and together
Finish with legs straight, together, and toes pointed
Breathing
Forward travel not halted to breathe
Timing
Perform one stroke cycle per kick cycle
Finish stroke and kick cycles at about same time
Pause and glide between cycles
Scoring
The following scoring rubric lists the gradients of key requirements and deficiencies that provide an overall description of different competence levels.
A single score of 1 - 4 is assigned based on the instructor’s judgment of the student’s performance.
