Dalbo, VJ、Roberts, MD、Stout, JR 和 Kerksick, CM。性别对市售生热饮料代谢影响的影响。 J Strength Cond Res 24(6): 1633-1642, 2010 - 本研究的目的是检查每日饮用含有咖啡因、表没食子儿茶素没食子酸酯和牛磺酸的生热饮料 (TD) 对性别的影响。在一项单盲、配对、安慰剂对照研究中，60 名参与者（n = 30 名男性和 n = 30 名女性）根据年龄和体重以平衡方式进行匹配。参与者在摄入 336 mL TD 或无热量、不含咖啡因的安慰剂 (PLA) 之前和之后完成了身体成分、静息能量消耗 (REE) 以及甘油和游离脂肪酸血清水平的测定。参与者每天补充 336 mL TD 或 PLA，并在第 28 天重复相同的测试程序。计算第 0 天和第 28 天的所有血液变量（例如甘油和游离脂肪酸）的曲线下面积 (AUC) 分析，并使用 REE、呼吸交换比、饮食记录和身体成分进行分析，并进行单独的重复测量方差分析。在第 0 天和第 28 天，所有男性的 REE AUC (p < 0.001) 均高于女性。与男性相比，摄入 TD 的女性游离脂肪酸 AUC 值显着更高 (p = 0.002)。甘油 AUC 的显着交互作用 (p = 0.02) 显示男性 PLA 组的甘油浓度较高，而其他所有组的甘油浓度从第 0 天到第 28 天均下降。男性 TD 组比女性 PLA 组损失的体脂百分比显着更高 (p = 0.02)。用于促进减肥和改变身体成分的产热饮料的受欢迎程度呈指数级增长。摄入饮料后的性别差异可能会影响由此产生的适应，以及将其纳入对那些遵循常规饮食和锻炼计划的人的减肥和身体成分变化的影响程度。
Dalbo, VJ, Roberts, MD, Stout, JR, and Kerksick, CM. Effect of gender on the metabolic impact of a commercially available thermogenic drink. J Strength Cond Res 24(6): 1633-1642, 2010-The purpose of this study was to examine the gender effect of daily consumption of a thermogenic drink (TD) containing caffeine, epigallocatechin gallate, and taurine. In a single-blind, matched-pairs, placebo-controlled study, 60 participants (n = 30 men and n = 30 women) were matched in a balanced fashion according to age and body mass. Participants completed determination of body composition, resting energy expenditure (REE), and serum levels of glycerol and free fatty acids before and after ingesting either 336 mL of a TD or a noncaloric, noncaffeinated placebo (PLA). Participants were supplemented daily with 336 mL of either the TD or PLA and repeated identical testing procedures on day 28. Area under the curve (AUC) analysis on days 0 and 28 were calculated for all blood variables (e. g., glycerol and free fatty acids) and analyzed with REE, respiratory exchange ratio, dietary records, and body composition with separate repeated-measure analyses of variance. On days 0 and 28, REE AUC (p < 0.001) was greater in all men compared with in women. Women ingesting the TD had significantly greater free fatty acid AUC values (p = 0.002) when compared with those of men. A significant interaction for glycerol AUC (p = 0.02) revealed greater glycerol concentrations in the male PLA group, which decreased in all other groups from days 0 to 28. The male TD group lost significantly more percent body fat (p = 0.02) than did the female PLA group. The popularity of thermogenic drinks to promote weight loss and body composition changes has grown exponentially. Gender differences after drink ingestion may impact the resulting adaptations and how successful their inclusion impacts weight loss and body-composition changes in those following a regular diet and exercise program.
