Characteristics of trunk acceleration for basketball players with the medical history of ankle sprain during repetitive tuck jump maneuvers and real game situation

Abstract

The characteristics of tuck jump measurement and trunk acceleration during a basketball game with a history of ankle sprain were determined in this report. A total of 25 female junior basketball players took part in this study and were divided into two groups: those with the presence of medical history of ankle sprain (12 players) and those with no relevant medical history (13 players). Both participants performed a 10-second tuck jump movement while sporting a tri-axial accelerometer on their upper back. In addition, they used the same sensor to play a 20-minute simulation basketball game. The frequency of high-loading situations produced over 4G, 6G, and 8G resultant acceleration was measured. The two groups were compared in terms of tuck jump evaluation ratings, magnitude of trunk acceleration during tuck jump landing, and frequency of high trunk acceleration during game scenarios. Compared to their counterparts, players with a history of ankle sprain demonstrated considerably greater trunk acceleration (vertical and resulting acceleration) during repeated tuck jump maneuvers. However, other parameters did not differ irrespective of a history of ankle sprain. These results indicated that characteristics of an ankle sprain, such as a stiff landing technique, prominently occur during a tuck jump exercise.
