Effects of time and movements of the preshot routine on free throw shooting.

This study examined the effects of length and movements of preshot routines on free throw shooting in basketball. 17 members of an intercollegiate men's basketball team attempted 20 free throws in each of four different conditions: (1) normal routine and time, (2) normal routine with altered time, (3) altered routine with normal time, and (4) altered routine with altered time. Free throw performance was measured using an objective 5-point scoring system. A multivariate analysis of variance indicated a significant effect for routine. Neither time nor routine by time was significant. Results indicated that altering the movements in the routine had a significant effect on performance while lengthening the time did not.
