Abstract

LANGUAGE NOTE | Document text in English; abstract also in Chinese.

The present randomized and double-blinded study investigated whether β-hydroxy-β-methylbutyrate (HMB) supplementation on low intensity training subjects had an effect on body composition and blood biochemistry. Fourteen recreational untrained college students participated in an eight-week low intensity resistant training. They were divided into two groups either an HMB group or a placebo group at the 5th week. Prior to beginning of the study a 1 RM max was performed at 1st week and again at the 4th week. 80% of 1 RM max was used as the training weight. The HMB group received 3g of HMB supplements per day from the 5th week to the 8th week. The body composition, blood biochemistry, and strength at 0 week and 8th week were measured. There were no significant differences (P<0.5) between the two groups in fat free mass, creatine kinase, endocrine profile, blood lipid profile and strength. Results indicated that low intensity training men ingesting HMB for 4 weeks did not provid any ergogenic benefit.

本研究主要探討補充β-羥基-β-甲基丁酸鹽(HMB)對低強度訓練者的身體組成和血液生化值是否有影響。研究對象為14位未受訓練的大學生參與8周的阻力訓練。在實驗開始前與第四周測量受試者的最大肌力,之後以80%最大肌力進行肌力訓練。HMB組於第5周至第8周每天補充3克的HMB,安慰劑組則補充安慰劑。於第1周和第8周測量每位受試者的身體組成、血液生化值和肌力。研究結果顯示這兩組在體脂肪百分比,肌酸激酶,內分泌,血脂和肌力沒有顯著性的差異(P<0.05),即低強度之阻力訓練,再予以補充4周HMB並無增強作用。
