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

When newly introduced swing changes are lost between lessons, it indicates that the swing changes have not been integrated effectively into the player's motor memory and overall understanding of the swing mechanics. Neural changes are crucial for skill acquisition and retention; they represent the brain's adaptations to the learning of new movements.

If a player doesn't consistently practice or reinforce the new swing changes, their ability to execute those changes diminishes, suggesting that limited neural changes have occurred. This can also be a sign that the player has not yet formed the necessary neural pathways or connections to make the new swing changes a routine part of their game. Continuous practice and reinforcement are essential to aid in those neural adaptations, and without them, the likelihood of maintaining new habits decreases.

Other options like significant motivation decrease or increased confidence don’t directly correlate with the loss of swing changes, as those feelings often depend on different aspects of the learning and playing experience rather than the biological or neural foundations of skill acquisition. Additionally, extensive progress seems unlikely in such a scenario where retention of learning is failing.
