Head and Shoulder Submersion  #

Introduction  #

The Head and Shoulder Submersion skill develops Breath Control CompetencyBreath Control CompetencyBreath Control Competency is the knowledge, skill, and experience necessary to breathe effectively in a controlled manner without using excessive energy, interfering with other movements, or compromising body position while in the water. Physical abilities associated with this competency include the physical exchange of air and keeping the body in a position at the surface so that the exchange of air can occur. Cognitive abilities include determining when to breathe and when to hold the breath. Affective abilities include responding to stimuli and situations in a calm manner with the face both above and below the surface of the water. and Underwater CompetencyUnderwater CompetencyUnderwater Competency is the knowledge, skill, and experience necessary to submerge and control buoyancy to travel and negotiate hazards underwater. Physical abilities associated with this competency include being able to use the limbs to propel, to control and hold the breath, and to control and change body position and direction. Cognitive abilities include understanding position and orientation in three-dimensional space, to understand the relationship between breathing and buoyancy, to monitor and compare one’s current position to surrounding objects, and to plan navigation paths. Performing tasks underwater also requires being able to cope with depth, pressure, and reduced visibility. . Head and Shoulder Submersion requires the student to submerge completely underwater, briefly hold their breath, and then resurface. This teaches students to be relaxed underwater, control their breath, and to return to the surface without panic. Being comfortable with their whole body and head under the water is an important skill should the student become unintentionally submerged. The ability to submerge and resurface comfortably is a component of other aquatic skills such as Stationary Bobs, Traveling Bobs, and other underwater skills.
