The purpose of this study was to examine the effects of a functional coffee beverage containing additional caffeine, green tea extracts, niacin and garcinia cambogia to regular coffee to determine the effects on resting energy expenditure (REE) and hemodynamic variables.
Subjects included five male (26 +/- 2.1 y, 97.16 +/- 10.05 kg, 183.89 +/- 6.60 cm) and five female (28.8 +/- 5.3 y, 142.2 +/- 12.6 lbs) regular coffee drinkers. Subjects fasted for 10 hours and were assessed for 1 hour prior (PRE) and 3 hours following 1.5 cups of coffee ingestion [JavaFittrade mark Energy Extreme (JF) ~400 mg total caffeine; Folgers (F) ~200 mg total caffeine] in a double-blind, crossover design. REE, resting heart rate (RHR), and systolic (SBP) and diastolic (DBP) blood pressure was assessed at PRE and 1, 2, and 3-hours post coffee ingestion. Data were analyzed by three-factor repeated measures ANOVA (p < 0.05).
JF trial resulted in a significant main effect for REE (p < 0.01), SBP (p < 0.01), RER (p < 0.01), and VO2 (p < 0.01) compared to F, with no difference between trials on the RHR and DBP variables. A significant interaction for trial and time point (p < 0.05) was observed for the variable REE. The JF trial resulted in a significant overall mean increase in REE of 14.4% (males = 12.1%, females = 17.9%) over the observation period (p < 0.05), while the F trial produced an overall decrease in REE of 5.7%. SBP was significantly higher in the JF trial; however, there was no significant increase from PRE to 3-hours post.
Results from this study suggest that JavaFittrade mark Energy Extreme coffee is more effective than Folgers regular caffeinated coffee at increasing REE in regular coffee drinkers for up to 3 hours following ingestion without any adverse hemodynamic effects.
本研究旨在检验一种含有额外咖啡因、绿茶提取物、烟酸和藤黄果的功能性咖啡饮料对普通咖啡的影响，以确定其对静息能量消耗（REE）和血液动力学变量的影响。
研究对象包括五名男性（26 ± 2.1 岁，97.16 ± 10.05 公斤，183.89 ± 6.60 厘米）和五名女性（28.8 ± 5.3 岁，142.2 ± 12.6 磅）的普通咖啡饮用者。受试者禁食 10 小时，并在双盲交叉设计中摄入 1.5 杯咖啡[JavaFittrade mark Energy Extreme（JF）400mg 总咖啡因；Folgers（F）200mg 总咖啡因]前 1 小时（PRE）和 3 小时后进行评估。在 PRE 和咖啡摄入后 1、2 和 3 小时评估 REE、静息心率（RHR）以及收缩压（SBP）和舒张压（DBP）。数据通过三因素重复测量方差分析进行分析（p < 0.05）。
JF 试验与 F 相比，REE（p < 0.01）、SBP（p < 0.01）、RER（p < 0.01）和 VO2（p < 0.01）均有显著的主效应，而 RHR 和 DBP 变量在试验之间无差异。试验和时间点之间存在显著的交互作用（p < 0.05）。在观察期间，JF 试验导致 REE 总体平均增加 14.4%（男性为 12.1%，女性为 17.9%）（p < 0.05），而 F 试验导致 REE 总体减少 5.7%。JF 试验中 SBP 明显升高；然而，从 PRE 到 3 小时后没有显著增加。
本研究结果表明，JavaFittrade mark Energy Extreme 咖啡在摄入后 3 小时内比 Folgers 普通含咖啡因咖啡更能有效增加普通咖啡饮用者的 REE，而无任何不良血液动力学影响。
