中文摘要 心率變異(Heart Rate Variability, HRV)代表自律神經整體的狀況，因此被廣泛用來探討自律神經的調節作用。自律神經失衡是因迷走神經功能低下，與疾病的發生率以及死亡率有正相關。影響HRV的因素有很多，其中鎂離子的角色逐漸被重視，另外運動相關研究也顯示可以提高HRV，尤其是持續性有氧運動。本研究參與者以臺南社區47位60歲以上的社區長者為受測對象，並依是否有足夠的鎂離子攝取，以及是否有足夠運動習慣共分成四組。以攜帶行動型心率變異檢測儀，配合社區活動時進行調查檢測，以及相關飲食以及運動習慣問卷調查。社區居民採自願參加，量測之前，均給予充分說明並填寫受測同意書以及自覺性症狀問卷。儀器檢測主要收集心跳變異率中時域部分的正常心跳間的標準差(Standard deviation of normal-to-normal, SDNN)，其數值的高低就代表自律神經整體活性的高低。結果顯示足夠的鎂離子且有運動習慣的組別比起缺乏鎂離子又無運動習慣者有較高的SDNN (p<0.001)，僅足夠鎂離子或僅有運動習慣者都比起鎂離子攝取低而且無運動習慣者有較好的SDNN (p<0.05)。結論，飲食中足夠的鎂離子，或者良好的運動習慣確實有助於長者提高SDNN，兩者兼具效果更好。

The effects of dietary magnesium ions and exercise habits on heart rate variability (HRV) in older adults population
Liu, M.-Y., Chen, M.-J.
English Abstract Heart rate variability (HRV) represents the total activity of autonomic nerves and it is widely used to explore the regulation of autonomic nerves. Autonomic imbalances, due to vagal dysfunction, are positively associated with morbidity and mortality. There are many factors that affect HRV, among which the role of magnesium ions is gradually emphasized. Furthermore, studies have also shown that HRV can be improved, especially by doing continuous aerobic exercise. Participants in this study who were over 60 years old were tested in a community center in Tainan. They were divided into four groups according to whether they had sufficient magnesium ion intake and whether they had sufficient exercise habits. Participants carried a mobile heart rate variability detector during the surveys and were tested during community activities. We also handed them questionnaires related to their diet and exercise habits. Community residents participated voluntarily. Before the study, they had all given full explanations about themselves and conditions. They also had to fill out a consent form and a subjective questionnaire based on their current living habits. Instrument detection mainly collects the standard deviation between normal heartbeats (SDNN) in the time domain part of the heartbeat variability. The results showed that the group with sufficient magnesium ions and exercise habits had a higher SDNN than the group without magnesium ions and no exercise habit (p<0.001). Those with only sufficient magnesium ion or only exercise habit had better SDNN than those with low magnesium ion intake and no exercise habit (p<0.05). In conclusion, we stress that sufficient magnesium ions in the diet or good exercise habits positively benefit the older adults to improve SDNN, and when combined together, effectiveness in improving HRV is stronger.Keywords：heart rate variability, dysautonomia, magnesium, exercise
