Twenty-four hour energy expenditure during a standard physical activity programme was investigated in 19 healthy volunteers in a randomized, double-blind, cross-over design, after supplementation with a soluble dietary fibre amounting 7 g/day for 2 weeks. Energy intake and food fibre intake were kept constant during the treatment period. Twenty-four hour energy expenditure decreased insignificantly during fibre treatment (1.3 +/- 1.7 per cent). The dietary fibre supplement also had no significant effect on body weight, faecal energy loss or heart rate. Systolic blood pressure was insignificantly reduced during both placebo and fibre treatment (P = 0.09). There was, however, no difference between the groups after treatment.
在一项随机、双盲、交叉设计中，对19名健康志愿者进行了研究，他们在补充了为期2周、每日7克的可溶性膳食纤维后，参与了标准体育活动计划，并对其24小时能量消耗进行了调查。在治疗期间，能量摄入和膳食纤维摄入量保持恒定。在纤维治疗期间，24小时能量消耗无显著下降（1.3±1.7%）。膳食纤维补充剂对体重、粪便能量损失或心率也没有显著影响。在安慰剂和纤维治疗期间，收缩压均有不显著降低（P = 0.09）。然而，治疗后两组之间没有差异。
