  The purpose of this study was to examine kinesthetic after-effects on shot-put performance. In experiment 1, involving 22 male university students, it was examined whether any kinesthetic after-effects would be evident in terms of throwing distance when shots of different weights were thrown. The results demonstrated a kinesthetic after-effect: the participants felt that it was easier to throw a standard-weight shot (4.0 kg) after throwing a heavier shot (5.45 kg), and they performed better in terms of throwing distance. However, no difference in throwing distance was evident when the standard-weight shot was thrown after throwing a lighter one (2.72 kg), although a kinesthetic after-effect was observed.<br>   In experiment 2, involving 16 male university students, it was examined whether any kinesthetic after-effect or improvement of throwing distance would result from throwing different weights of heavier shots (5.0 kg and 6.0 kg) before throwing the standard-weight shot (4.0 kg) 5 times. Kinesthetic after-effects and improvements in throwing distance were observed. However, there was no difference in the distances of the five throws corresponding to the weights of the shots.<br>   In experiment 3, involving 27 male university students, it was examined whether any kinesthetic after-effect or improvement in throwing distance would be evident when there was a difference in time interval after throwing a heavier shot (6.0 kg). Although kinesthetic after-effects and improvements in throwing distance were observed, there was no difference according to time interval.<br>   The above results suggest that shot-put performance would improve due to after-effects caused by throwing heavier shots. This improvement in performance might be explained by ‘post-activation potentiation’ and ‘perceptional illusion’ resulting from throwing heavier shots.<br>
