A140: Kinetic Comparison Of Weightlifting Pulling Derivatives With Different Starting Positions, Junhao Chen, Junlin Tian, Songgula Jumaali, Yuduo Liu, Xianglin Wan

International Journal of Physical Activity and Health

Weightlifting movements have been shown to provide a superior training stimulus for force and power development. Among these, Weightlifting pulling derivatives (WPDs) without the catch phase may generate superior kinetic stimulation compared to the full weightlifting movements. Previous studies have confirmed that the starting position significantly affects the peak vertical ground reaction forces (Fz), peak rate of force development (RFD), and peak power of the weightlifting derivatives with the catch phase. However, the influence of starting position on WPDs is still unclear. Therefore, this study aims to compare the kinetic performance differences of WPDs with different starting positions to optimize …

A152: Effect Of Stroboscopic Visual Perturbation On Posture Control In Patients With Chronic Ankle Instability, Mengyu Liu, Zhipeng Zhou, Yurui Shen, Liangliang Zheng

International Journal of Physical Activity and Health

Chronic ankle instability (CAI) is a common sports injury, often accompanied by reduced proprioception, muscle weakness, and impaired balance. Its etiology is often attributed to inadequate rehabilitation following initial ankle sprains, resulting in ligament laxity or damage. This study aimed to investigate whether stroboscopic visual disturbance influences static and dynamic postural control in individuals with CAI, thereby exploring the relationship between visual input and postural stability. Method: Thirty college students with unilateral CAI (9 males, 21 females; age: 21.3±1.2 years, height: 168.1±9.8 cm, weight: 63.5±11.6 kg) were recruited.

A154: Effects Of Stroboscopic Vision On Static Postural Control In Individuals With Chronic Ankle Instability, Yurui Shen, Mengyu Liu, Jingkun Zhang, Ting Lai, Zhipeng Zhou

International Journal of Physical Activity and Health

Chronic ankle instability (CAI) is a syndrome characterized by persistent dysfunction resulting from repeated ankle sprains, often leading to impaired postural control in affected individuals. Although rehabilitation training on unstable surfaces is effective for patients with CAI, it does not sufficiently reduce their reliance on visual input. While eye-closure training can restrict visual input, it poses safety risks and exhibits low compliance rates. Stroboscopic vision may offer a safe and effective alternative; however, its efficacy in reducing visual reliance among CAI patients on unstable surfaces remains unclear. Therefore, this study aimed to assess the impact of stroboscopic vision on static …
