同時個人排便和運動習慣對FC的發生亦有很大影響，刻意抑制排便後，排便反

At the same time, personal defecation and exercise habits also have a great impact on the occurrence of FC. After deliberately suppressing defecation, the defecation reflex will be triggered after several hours or more feces enter the rectum (Gong Ming and Li Yan, 2009). The longer it stays in the large intestine, the excess water will be absorbed, which will lead to hard and hard stools (Vriesman, Koppen, Camilleri, Di Lorenzo, & Benninga, 2019). Lack of exercise can cause changes in bowel motility and slow down transit time in the colon (Mugie, Benninga, & Di Lorenzo, 2011).

同時個人排便和運動習慣對FC的發生亦有很大影響，刻意抑制排便後，排便反射需经几小时或有更多粪便进入直肠才會被觸發（貢鳴、李岩，2009），當糞便在大腸內停留時間越長,水分會被過量吸收，繼而引起糞便乾硬難解(Vriesman, Koppen, Camilleri, Di Lorenzo, & Benninga, 2019)。缺乏運動則會引起腸蠕動變化，使結腸的轉運時間減慢(Mugie, Benninga, & Di Lorenzo, 2011) 。

At the same time, personal defecation and exercise habits also have a great impact on the occurrence of FC. After deliberately suppressing defecation, the defecation reflex will not be triggered until a few hours or more feces enter the rectum (Gongming, Liyan, 2009). When the feces stay in the large intestine for a longer time, the water will be absorbed excessively, and then the feces will become hard to digest (vriesman, Koppen, Camilleri, di Lorenzo, & benninga, 2009), 2019)。 Lack of exercise can cause intestinal peristalsis and slow down the transit time of colon (mugie, benninga, & Di Lorenzo, 2011).<br>
