What is lacking when newly introduced swing changes are lost between lessons?

When newly introduced swing changes are lost between lessons, it indicates a deficiency in the amount of neural change that has taken place. Neural change refers to the alterations in brain pathways and connections that occur as motor skills are learned and refined. For swing changes to become ingrained and automatic, the brain must adapt through repeated practice and reinforcement of the new movements.

If there is not enough neural change, it suggests that the new swing techniques haven't been sufficiently practiced or internalized, making it easy for an athlete to revert to previous habits. This process emphasizes the importance of consistent practice and reinforcement of the new skills in order to solidify the learning within the brain's neural framework.

In the absence of significant neural change due to inadequate practice or reinforcement, the golfer may struggle to maintain the benefits of the swing alterations introduced in lessons, leading to a reversion to their old, familiar swing patterns. This highlights the necessity of not only understanding swing mechanics but also consistently engaging in practice to foster sustained neural adaptations.
