Introduction  #

The Stationary Bobs 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. as a primary competency 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. as a secondary competency. Stationary Bobs further develops competencies introduced in Head and Shoulder Sumbersion by asking students to completely submerge and resurface multiple times. The goal is to teach students to be comfortable inhaling and exhaling during multiple submersions, as well as repeatedly putting their face under the surface without wiping the water away. The ability to submerge and re-submerge is a component of aquatic safety skills, such as Traveling Bobs and Underwater Swim.

Description  #

The Stationary Bobs skill is defined by the following body posturePostureThe particular way the body is held while doing an activity. Mobility specialists define posture as the way you position your body or arrange your limbs, such as “to stand up straight with your shoulders back and your chin up.” , arm formsFormThe visible shape or configuration of something. Mobility specialists define form as an arrangement of the elements in a composition; the way something (or someone) is shaped or arranged. , leg forms, breathing, and timing characteristics and features.

Stationary Bobs Description  #

This skill may be performed using the pool bottom, deck, or wall for support.

Body

  1. Body positioned vertically
  2. Hands away from face; does not cover mouth, does not hold or plug nose, does not wipes eyes between bobs

Bobbing cycle

  1. Start with head above surface
  2. Inhale once
  3. Fully submerge head
  4. Exhale bubbles through nose
  5. Return head above surface

Timing

  1. Repeat bobbing cycle without hesitation

Scoring  #

The following scoring rubricScoring rubricA guide that includes rating scales and descriptions of one or more criteria used to evaluate the performance of a skill. lists the gradients of key requirements and deficiencies that provide an overall description of different competence levels. A single score is assigned based on the instructor’s judgment of the student’s performance.
