Purpose: To compare the shooting arc and release speed of misses versus swishes of free throws with smart sensor basketball, and whether the optimal mode of free throws could be found and the smart sensor basketball could be applied practically. Methods: Fifteen elite basketball players were recruited as subjects, to perform free throws for 30 times. A smart sensor basketball was used to collect the shooting arc and release speed, and the misses or swishes of free throws were recorded as well. Dependent T-test was used to compare the difference between misses or swishes. Results: The shooting arc of swishes of free throws were significantly higher than misses (39.3° ± 5.7 versus 35.0° ± 5.5), but no significant difference was found in the release speed. Conclusions: In the fixed shooting distance, the higher shooting arc could increase the percentage of goal. A smart sensor basketball could be applied practically for a real-time feedback of shooting arc in order to adjust the fine shot motion.
