青少年聽覺障礙因聽覺刺激的受限，常伴隨感官統合困難與大腦可塑性改變，進而影響執行功能之發展。執行功能作為高階認知的核心，包括計畫、抑制控制與認知彈性等能力，對於學業學習與日常生活適應具有關鍵影響。雖研究指出身體活動量較高的青少年在執行功能表現上具優勢，但針對聽覺障礙族群的相關研究仍屬有限，其關聯性有待釐清。本研究採橫斷式設計，共招募 40 位年齡介於 13 至 18 歲之青少年聽覺障礙。以國際身體活動問卷評估身體活動量，並進行身體適能測驗，包括瞬發力、肌耐力、柔軟度、身體質量指數、心肺適能及平衡能力。執行功能評估則涵蓋三項認知作業：倫敦塔作業 (計畫能力)、路徑描繪測驗 (認知彈性) 與叫色測驗 (抑制能力)。資料分析採用Spearman等級相關，並以 Benjamini–Yekutieli 法校正多重比較所致之假陽性機率上升。結果顯示，身體活動量與計畫能力表現呈顯著關聯；瞬發力與三項執行功能表現呈顯著關聯；肌耐力與認知彈性、抑制控制表現呈顯著關聯；睜眼靜態平衡亦與計畫能力表現具有顯著關聯。總而言之，身體活動與特定的身體適能表現，可能對該族群之執行功能具正向作用，未來可據此發展以認知功能為核心之身體活動介入策略，以促進其學習表現與生活適應能力。

Adolescents with hearing impairment may experience atypical sensory integration and altered brain plasticity due to limited auditory input, potentially affecting the development of executive functions. These functions planning, inhibitory control, and cognitive flexibility are critical for academic success and daily life adaptation. While prior research has linked higher physical activity levels to better executive function in the general adolescent population, evidence among adolescents with hearing impairment remains limited. This cross-sectional study investigated the associations between physical activity, physical fitness, and executive function in this population. Forty adolescents aged 13–18 years with hearing impairment were recruited. Physical activity levels were assessed using the International Physical Activity Questionnaire, and physical fitness was measured via tests of muscular power, muscular endurance, flexibility, Body Mass Index, cardiorespiratory fitness, and balance. Executive function was evaluated using the Tower of London (planning), Trail Making Test-B (cognitive flexibility), and Stroop test (inhibitory control). Spearman rank correlations were conducted, with the Benjamini–Yekutieli procedure used to control for multiple comparisons. Results revealed significant positive associations between physical activity and planning ability; muscular power and all three executive functions; muscular endurance with cognitive flexibility and inhibitory control; and static balance (eyes open) with planning. These findings suggest that specific fitness components may support executive function in adolescents with hearing impairment, providing a foundation for developing cognitively focused physical activity interventions for this population.
