- 概要（英）
- Watching instructional movies has been proposed as a way to enhance lower limb power output in plyometric training. However, the optimal visual search behavior for immediate performance improvements remains unclear. This study examined visual search behaviors associated with improved drop jump (DJ) performance after an instructional movie intervention. Twenty physical education students (5 male, 15 female; age: 21.45 ± 1.79 years; height: 165.28 ± 7.79 cm; weight: 61.32 ± 6.89 kg) were categorized into Increased (DJ-index improved) or Decreased (DJ-index declined) groups based on individual response to the movie intervention. DJ were performed under Normal (no movie) and Movie (DJ immediately after watching the instructional movie) conditions. A linear mixed model (LMM) analysis revealed significant individual differences in DJ performance ( p = 0.003), suggesting that personal movement characteristics influenced responsiveness to the intervention. The Increased group exhibited a higher DJ-index after the movie, whereas the Decreased group showed the opposite trend. During the pre-set phase, Increased group participants focused more on the hip region, while Decreased group participants fixated on the foot area. These findings suggest that observing full lower limb motion while emphasizing the hip joint enhances takeoff timing through spatial-temporal anticipation.
