Exercise D-6.1 Head and snorkel position (in the water) Reestablish proprioceptive reference points despite immersion
Level: Beginner
Theme: Familiarization with the front snorkel
Head and snorkel position (in the water)
Exercise D-6.1 Snorkel and head position -In the water
Objective

Reestablish and stabilize head and snorkel positioning reference points in the water by differentiating proprioceptive sensations from exteroceptive sensations related to immersion.

Instructions

* Lie flat at the surface of the water, with your face immersed using the snorkel
* Let the body float without tension
* Adopt the correct head position (look at the bottom of the pool without lifting or lowering the chin, pull the neck backward to create a slight double chin)

* Release the position / Re-take the position
* Repeat this alternation several times (positioning / release)
* Focus your attention on proprioceptive sensations (neck, chin)
* Observe exteroceptive sensations related to the water (contact, flow, waves, temperature, pressure)
* Differentiate these sensations from the proprioceptive sensations related to head position (reference exercise D-1.1)

Performance criteria

* The head remains aligned with the body
* The chin is neither lifted nor lowered
* The neck is pulled backward, creating a slight double chin
* The tip of the snorkel remains above the water surface

* The alternation between positioning and release is performed slowly and without jerks
* Attention remains focused on proprioceptive sensations despite disturbances from the water

Success criteria

* I keep my head aligned with my body without effort
* I neither lift nor lower my chin
* I feel my neck being pulled backward
* I feel a slight double chin naturally forming
* I feel that the tip of the snorkel remains above the water without adjustment
* I can alternate between positioning and release without losing my reference points
* I remain focused on my internal sensations despite the sensations from the water
* I clearly distinguish sensations related to the water from those related to my position
* I easily find again the reference points identified out of the water (D-1.1)
* I realize that my head floats if I let it go in the water

Points to watch

You move from a vertical position to a horizontal one, from a terrestrial environment where support is stable to an aquatic environment where support is unstable, with the body floating. The environment and your reference points change completely. The water generates many exteroceptive sensations (contact, pressure, movement) that can quickly overwhelm your attention. It is therefore essential to accept these sensations without trying to ignore them, and above all to differentiate them from the proprioceptive sensations identified in exercise D-1.1. The task is to remain focused in order to rediscover these internal sensations despite the increase in external sensory input.

These proprioceptive sensations — particularly the neck being pulled backward and the slight double chin — make it possible to confirm that the head position is correct and actively aligned, but not only that. This position also ensures that the tip of the snorkel moves sufficiently away from the water surface, thus preventing any water from entering. Note that the ylon-a front snorkel is beveled at its tip in order to facilitate the passage of water over the snorkel and prevent it from being directed inside.
