Why is touching the bottom of the pool sometimes allowed during transitional depth training?

Touching the bottom of the pool during transitional depth training can be permitted primarily for adjusting posture. When participants are allowed to touch the pool floor, it provides them with a tangible reference point, which can help them develop a better awareness of their body position in the water. This is particularly important for those who are learning to find their balance and maintain proper alignment while performing aquatic exercises. By having the option to touch the bottom, individuals can experiment with their posture, making the necessary adjustments to improve their technique, stability, and overall effectiveness in the water.

While other options might touch on various aspects of training or comfort, the primary focus in transitional depth training is to enhance the participant's ability to execute movements correctly and confidently, making posture adjustment the most relevant reason for allowing contact with the pool bottom.
