無意間發現於2016年8月發表的論文,隨手翻譯供各位巨巨參考
研究者找來34位至少有5年健身經驗,平均約身高178cm、體重84Kg、體脂13%、29歲的男
性(剔除曾使用類固醇者),分成斷食組(TRF)及正常組(ND)進行為期8周的實驗。
於飲食方面:
兩組飲食量相同,皆攝取每日所需熱量總量(TEDD),其中碳水,蛋白質,脂質比例約為
50%,25%,25%,蛋白質攝取量到達1.9g/KG的量。
斷食組(TRF)於1pm、4pm、8pm進食,其攝取之卡路里量分別為總量之40%、25%、35%
正常組(ND)則於8am、1pm、8pm進食,其攝取之卡路里量分別為總量之25、40%、35%
運動方面:
每周不連續日於4~6pm進行3次訓練,3次訓練內容如下:
訓練計畫A:臥推、胸飛鳥、二頭肌彎舉
訓練計畫B:槓鈴肩推舉, 腿推蹬, 腿伸屈, leg curl
訓練計畫C:正手下拉、反手下拉、三頭肌下壓
每個動作進行3組,每組6~8下,重量為85~90%1RM
測量8周前後實驗者身體組成(FFM、FM等)、力量(Bench press 1-RM 等)及賀爾蒙(睪固酮
、IGF-1 生長因子、瘦素等)的變化,
結果發現正常組(ND)各數值無明顯變化,而斷食組(TRF)方面:
1.在除脂體重(FFM)無明顯變化的情況下體脂肪明顯下降(10.9kg下降至9.28kg、
體脂12.97%下降至11.18%)
2.睪固酮、IGF-1 生長因子濃度明顯下降
3.血糖及胰島素濃度明顯下降
4.胰島素阻抗性(HOMA-IR )明顯改善
5.脂聯素(adiponectin)濃度提升
6.瘦素(leptin )濃度下降(但與脂肪重正規化後不明顯)
其他:T3及 respiratory ratio 明顯下降、TSH及 lipids 無明顯變化、 TG下降、TNF-
α及IL-1β較低。
研究者結論:研究結果建議間歇性斷食(16/8)搭配重訓,對於有重訓習慣的男姓可能可在
維持肌肉重量的情況下同時降低體脂肪,且提升某些健康指數。
提醒:
1.實驗週期僅八周,對於長期間歇性斷食(16/8)者影響不明
2.睪固酮、IGF-1 生長因子濃度明顯下降
3.樣本數僅34個
4.非本科系人員粗略翻譯,若有原文理解上錯誤請見諒
論文名稱:Effects of eight weeks of time-restricted feeding (16/8) on basal
metabolism, maximal strength, body composition, inflammation, and
cardiovascular risk factors in resistance-trained males
