Objective: The purpose of this study is to investigate the influences of HRV after Ear Auris-point pressing during incremental cycling exercise in male adults. Analyzing the changes of automatic nervous system during low, moderate and high-intensity exercise explored the possibility to enhance heart’s automatic nervous system by Ear Auris-point pressing in Sports. Methods: 25 male adults (age: 25.50 ± 2.08 years, height: 174.05 ± 7.56 cm, weight: 67.03 ± 9.68 kg, BMI: 22.04 ± 1.96 kg/m2 ) were recruited for this study. All of the subjects were in good health without any physical injuries or problems and Chinese medical treatment within last 6 months, and participated in this research voluntarily. Each subject was conducted to complete an incremental cycling exercise after Ear Auris-point pressing. HRV’s data were being recorded during exercise and analyzed in Low, moderate and high level of exercise. Results: 1) No any significant differences of Heart rate (HR), Total power (TP), Very Low frequency (VLF), Low frequency (LF) and High frequency (HF) were found at rest and at any stage of the incremental cycling exercise between experiment days and control day (p>0.05). 2) There were significance differences of LF and HF in normalized units as well as the ratio of LF and HF in Low level exercise between experiment days and control day (p0.05). HF in normalized units on experiment day 1 or experiment day 2 was significantly lower than that of on control day. Also, no difference was found between experiment days (p>0.05). Conclusion: After Ear Auris-point pressing, LF in normalized units was increased and HF in normalized units decreased during low level exercise. The result showed that Ear Auris-point pressing enhanced LF in normalized units and HF in normalized units during low level exercise. Due to the relativity between HRV and the sympathetic nervous system activity and parasympathetic nervous system activity, Ear Auris-point pressing might have beneficial for cardiovascular system during low level exercise. There was no time effect of Ear Auris-point pressing during incremental cycling exercise.

研究目的：本研究旨在探討耳穴貼壓後對遞增負荷踏車運動過程中心率變異(HRV)變化的影 響，透過分析低強度、中等強度及高強度的運動狀態下耳穴貼壓對自主神經系統的作用，探 討耳穴貼壓在不同運動強度時，是否存在對心臟神經系統機能的良好影響，為耳穴貼壓應用 於體育運動實踐提供可行性的實證參考。 研究方法：研究對象為 25 名成年男性，身體健康，自身並無任何疾病史，自願參與本研究， 過去半年無任何外傷史，亦未受過任何中醫藥治療，年齡為 25.50 ± 2.08 歲，身高為 174.05 ± 7.56 厘米，體重為 67.03 ± 9.68 公斤，身體質量指標為 22.04 ± 1.96 公斤/米 2 。研究對象需要 分別接受即時性耳穴貼壓和連續 14 天耳穴貼壓的刺激，並且完成遞增負荷踏車運動測試，記 錄運動過程中心率變異數據，分析低、中及高強度運動過程中耳穴貼壓對受試者心率變異的 影響。 研究結果：1、實驗日與對照日之間，安靜狀態及遞增負荷運動時心率(HR)、總功率(TP)、極低 頻功率(VLF)、低頻功率(LF)、高頻功率(HF)均無顯著差異(p>0.05)；2、低強度運動中實驗日與 對照日之間，低頻功率標準化(LFn)、高頻功率標準化(HFn)及低高頻功率比例(LF/HF)均存在明 顯差異(p0.05)；高頻功率標準化(HFn)於即時性耳穴貼壓(實驗日 1) 及連續 14 天耳穴貼壓(實驗日 2)均低於對照日，而即時性耳穴貼壓(實驗日 1)與連續 14 天耳穴 貼壓(實驗日 2)之間並無明顯差異(p>0.05)。 結論：耳穴貼壓於低強度運動過程中，心率變異的低頻功率標準化(LFn)上升而高頻功率標準 化(HFn)下降。研究結果顯示即時性耳穴貼壓及連續 14 天耳穴貼壓均能改善人體於低強度運動 中心率變異的低頻功率標準化(LFn)及高頻功率標準化(HFn)，由於這兩個指標與心臟交感神經 及迷走神經系統有密切關系，因此耳穴貼壓可能有利神經系統於低強度運動中的表現；耳穴 貼壓時間不同，運動中心率變異的低頻功率標準化(LFn)及高頻功率標準化(HFn)的反應相同。 關鍵字：耳穴貼壓、遞增負荷運動、心率變異、交感神經系統、迷走神經系統
