The seated pumping exercises on the high chair are aided by:

The seated pumping exercises on the high chair involve the use of both stability and support that are critical for proper execution and effectiveness. Proprioceptive feedback, which is the body’s ability to sense its position and movement, is enhanced when participants utilize the back board. This feedback helps in maintaining balance and alignment while performing the movements. The support from the back board allows the individual to focus on the pumping action without overcompensating or straining.

This aspect of proprioception is crucial for developing control and awareness of the body during exercises. The back board serves as both a physical support and a guide for alignment, ensuring that the movements are performed safely and effectively.

While lighter springs can assist in movement and a padded seat can increase comfort, they do not provide the same level of feedback and support as the back board does. The height of the seat, while it may affect the accessibility of the exercise, is secondary to the stabilizing and guiding role that the back board plays during the seated pumping exercises. Thus, the correct answer accurately reflects the importance of proprioceptive feedback and the supportive role of the back board in these exercises.
