中國時報【閻紀宇／綜合報導】
「沙發馬鈴薯」和總是坐著辦公的上班族要注意了，就算飲食講究健康法則，平日勤於運
動，但只要日常生活中長期採取坐姿，就要小心肥胖上身，臀部尤其容易橫向擴張，讓下
盤越來越可觀。
最新研究顯示，長期坐姿可能會刺激脂肪細胞，產生的脂肪較正常值增加五十％。領導這
項研究的以色列特拉維夫大學教授葛芬指出，肥胖不只是熱量失衡而已，細胞本身會對環
境起反應，長期躺姿或坐姿會導致脂肪細胞過於活躍。
研究團隊在實驗室中培養脂肪細胞，分成兩組，實驗組脂肪細胞處於模擬久坐或久躺的「
機械性展延負荷」（mechanical stretching loading）狀態，對照組則否。四星期後，
研究人員發現，實驗組細胞的脂肪含量是對照組的一．五倍。相關論文刊登在最新一期的
《美國生理學期刊─細胞生理學》。
葛芬先前另一項研究則顯示，因為脊椎損傷而癱瘓在床的病患，很容易出現肌肉失養萎縮
的現象，而且脂肪細胞會趁隙而入身體各個部位。葛芬提醒一天到晚坐在辦公桌前的上班
族，最好能夠調整生活習慣。
