目的：高強度的訓練和比賽狀態，使得運動員在三度空間中産生空間錯覺，導致控制身體的視神經、前庭神經、自律神經等，傳送錯誤訊息給大腦，容易引發動暈症進而造成動態追視能力以及心率變異調控的影響，導致運動後期效應的負面反應。因此，本研究之目的在探討空間迷向訓練前、後，對於動態追視能力和整體性心率變異指標的差異及相關，企圖解釋造成動態追視能力變化以及影響心率變異的負面效應。方法：依據IRB（Institutional Review Board）的規範篩選30名男性運動員，在多軸訓練儀上進行空間迷向的訓練，在訓練前、後採用心率紀錄儀、三度空間運動視覺系統進行測驗。結果：研究結果發現，深度動態追視能力在前測為8109.5、後測為9314.4 具有顯著差異;在整體性心率變異指標前測為84.2、後測為36.9也有達顯著差異，另外在SDNN（Standard Deviation of all Normal to Normal）與深度動態追視能力的積差相關為0.72達顯著水準。結論：結論得知，空間迷向訓練所創造出的壓力，來自於訓練中對於頭部刺激的動暈現象，使運動員面對空間的變化產生壓力刺激，誘發在深度動態追視能力和心率變異的變化呈現正相關，此研究所證實的現象，對於未來研究、高強度的訓練和比賽，有助於提供具體參考且實務的應用價值。

Purpose: Intense sports training and competition assimilate into the three-dimensional motion were caused spatial disorientation. The Nervous system controls such as vision, vestibule and heart rate were not working properly and the wrong message transmission to the brain. Previous research found that were induced motion sickness. In addition, the dynamic vision tracking ability and the heart rate variability regulation were which bring to a negative reaction effects after exercise. Therefore, the purpose of this study was to explore the differences and correlations between the dynamic vision tracking ability and the heart rate variability SDNN index pre and post the 3D spatial training. Methods: There are 30 male athletes participated in this study and screened according to the IRB specifications, and the 3D spatial training was performed on a multi-axis training device, a heart rate recorder and a three-dimensional spatial motion vision system were used for testing during pre and post training. Results: The results were showed significant difference in the depth of dynamic vision tracking ability at the pretest 8109.5 and the posttest 9314.4, the SDNN index also had significant differences at the pretest 84.2 and posttest 36.9, on the other, it was significant correlation at 0.72 between SDNN and depth dynamic vision tracking ability. Conclusions: In conclusion, the pressure induced motion sickness phenomenon by 3D spatial training from stimulation training. There was also a substantial body of evidence that would support the argument in this study and found the reason from positive correlation between deep dynamic vision tracking ability and heart rate variability due to the adaptation ability of athletes. It will useful for the future research and application in high intensity training and competition.
