Abstract：Previous studies demonstrated that external focus on movement could enhance the motor performance than internal focus on body movement. However, recent studies provided inconsistent results for expert players, especially the role of interoceptive focus remains unclear while experts performing the movement. This study aimed to examine how the instruction of interoceptive focus and external focus influenced the hitting performance among expert hockey players. Using the within-subjects design, thirteen senior high school hockey players (age = 16.7 ± 1.0 years, training experience = 3.3 ± 1.3 years) performed 2 hits following different sets of verbal instructions (interoceptive focus and external focus). Participants completed 4 trials for a testing session. The results showed that the hitting scores of the expert hokey players were significantly higher with interoceptive focus instruction than that of the external focus instruction. It was concluded that compared to external focus, the interoceptive focus instruction enhance the hitting performance of expert hokey players. (Full text)
