低氧艙訓練對中長跑者認知表現之影響
The Impact of Hypoxic Chamber Training on the Cognitive Performance of Middle-Distance and Long-Distance Runners
摘要
目的：本研究旨在探討低氧艙訓練對中長跑運動員認知功能的影響，特別是對空間反應啟動能力與視覺空間短期記憶之提升效果。方法：研究採用對照實驗設計，受試者以中長跑運動員為對象，隨機分為實驗組與控制組。實驗組在低氧艙內進行跑步機訓練，控制組則在正常氧氣環境下進行相同之跑步機訓練。兩組均在訓練前後進行認知功能測試，內容包括空間反應啟動能力與視覺空間短期記憶，並收集相關生理數據如心率和血氧等。結果：實驗組在低氧訓練後，空間反應啟動能力提升情形顯著，尤其是在不同提示條件下之反應時間均顯著縮短。另於視覺空間短期記憶測試中，實驗組在各項指標表現上均有顯著提高，顯示出記憶容量、正確性及穩定性有提升。相較之下，控制組在大多數變項上之前後測結果未見顯著變化。結論：低氧艙訓練對中長跑運動員的認知功能具有顯著積極之影響，特別是在空間反應啟動能力與視覺空間短期記憶方面的表現。

Objective: This study aims to explore the effects of hypoxic chamber training on the cognitive functions of middle- and long-distance runners, specifically focusing on the enhancement of spatial reaction initiation ability and visuospatial short-term memory.Methods: The study utilized a controlled experimental design with middle- and long-distance runners as subjects, randomly divided into an experimental group and a control group. The experimental group underwent treadmill training in a hypoxic chamber, while the control group performed the same treadmill training in a normoxic environment. Both groups underwent cognitive function tests before and after training, which included assessments of spatial reaction initiation ability and visuospatial short-term memory. Relevant physiological data such as heart rate and blood oxygen levels were also collected.Results: The experimental group showed significant improvement in spatial reaction initiation ability after hypoxic training, with notably reduced reaction times under various cue conditions. Additionally, in the visuospatial short-term memory tests, the experimental group demonstrated significant improvement across all indicators, showing increased memory capacity, accuracy, and stability. In contrast, the control group did not exhibit significant changes in most variables between the pre- and post-tests.Conclusion: Hypoxic chamber training has a significantly positive impact on the cognitive functions of middle- and long-distance runners, particularly in the areas of spatial reaction initiation ability and visuospatial short-term memory.
