博士 === 國立臺灣師範大學 === 體育學系 === 100 === This study was designed to examine the effects of visual contexts, conditions of performance, skill levels, and amounts of practice on basketball free-throw’s especial skill. Twelve expert male basketball players served as participants in experiment 1. Each participant performed 20 set shots at two visual contexts and alteration distance-force conditions. Dependent variable was shooting accuracy. Two way repeated measures ANOVA and simple linear regression analysis revealed that (1) The accuracy of free-throw shooting was found no significant difference on visual context. The actual and expected values at the foul line were found no higher than one SEest in both specific and non-specific foul line visual contexts; (2) In two visual contexts, the accuracy of free-throw shooting between foul line and closer distances were found no significant difference; and (3) For accuracy of free-throw shooting, significant difference was found in performance variable. The actual and expected values at the foul line was found no higher than one SEest in both specific and non-specific distance-force conditions. Twelve expert female basketball players and twelve basketball-experienced female students served as participants in experiment 2. Each participant performed 200 set shots at normal and low perception-action conditions. The mixed-design three-way ANOVA analysis revealed that skill level and amounts of practice were found significant difference. The actual and expected values at the foul line was no higher than one SEest in both normal and low perception-action conditions. It was concluded that: (1) Visual context had no effect on especial skill of free-throw shooting; (2) The generalization effects of especial skill was found in neighboring shooting distances; (3) Different distance-force conditions had no effect on especial skill of free-throw shooting; and (4) Skill levels and amounts of practice had effects on especial skill of free-throw shooting.
