The effects of form training on foul-shooting performance in members of a women's college basketball team.

Three women on a college basketball team could not hit free throws. The coach gave each player a short form lesson. After every shot he told her what to fix. Sessions lasted about 15 minutes.

The coach kept charts. He ended training when a player hit 80 % of shots with good form for two sessions in a row.

All three players reached the goal within seven short practices. Their shots looked better and went in more often. The gains stuck when the coach stopped giving feedback.

Morante et al. (2024) got the same fast jump in adult runners using phone video instead of a live coach. Cochrane et al. (2022) show peers can give the video feedback after a quick BST package. Together these studies say "feedback on form works" and "you can deliver it many ways."

Hemayattalab et al. (2010) seems to disagree. Teens with intellectual disability improved most when they first pictured the shot in their head, then shot. The 2001 study did not test mental practice. The clash fades when you see the groups differ: college players already have strong bodies; teens with ID need extra help to plan the move.

Koop et al. (1983) found the same coach loop cut stroke errors in child swimmers. The pattern holds across sports and ages.

You do not need long drills or fancy gear. A few minutes of clear, form-focused feedback gives big, fast gains. Try it next time you teach any motor skill—free throws, tooth-brushing, or data-sheet use. Watch the learner, name one fix, let them try again, and chart the result. Stop when they hit mastery for two rounds.
