阻力運動對於中風防治之應用

The application of resistance exercis for stroke prevention

腦中風是造成國人嚴重失能的重要原因，預防此疾病的發生儼然成為一個重要的課題。阻力運動不僅可以控制體重、血糖、膽固醇和血壓，長期運動下更能有增加肌肉質量改善心血管功能的效果，因此臨床上也常被應用在中風的復健。但是若以預防中風發生為目的，如何擬訂有效的阻力運動策略，尚未有相關的討論。本文經統整中風復健的課程後發現：使用漸進式強度20%-80%，每周3次，每次3回合、每回合10下的阻力運動，才能對身體功能有幫助。在預防策略上，由於尚未出現中風現象，因此運動強度可較復健課程提高，建議可以從中強度的60% 開始，並採用漸進式強度至80%。未來亦可以針對阻力運動的儀器從神經肌肉運動與訓練的理論進行改良，使得運動傷害風險降低，又可增加對肌肉的刺激，相信必能成為中風高風險者的一大福音。

Stroke is one of the main reason for disability in Taiwan. Therefore, to prevent the occurrence of stroke has become an important issue. Resistance exercise can keep lower body weight, blood sugar, cholesterol and blood pressure, and the long-term resistance exercise was demostrated effectively to increase muscle mass and then to improve cardiovascular function, which has been used in chinical stroke rehabilitation. In order to prevent stroke by resistance exercise, no study had demostrated the valid strategy. After the system review of stroke rehabilitation programs, this study were found: the resistance exercise with the progressive intensity 20% -80%, 10 repetitions per round, 3 rounds per time and 3 times per week, would be effective to enhance the body function. Because stroke has not occured yet, the strategy of resistance exercise for prevention purpose can be started from 60% of intensity, and progressively increased up to 80%. We also suggested that the exercise equipment could be improved in order to comform to the neuromuscular training theories, and thus to induce more muscle stimulation and to reduce the risk of injury for the stroke reasons.
