It has been suggested that the consumption of energy drinks (ED) may affect cardiovascular activity.
to investigate the acute effects of ED intake on heart rate variability (HRV) and cardiovascular recovery after moderate aerobic exercise in males with different cardiorespiratory capacities.
This is a randomized, double-blind, crossover, placebo-controlled study. Twenty-eight young adults were split into two groups according to their peak oxygen consumption (VO2peak) values: (1) High VO2 peak (HO) - VO2 peak > 52.15 mL/kg/min, and (2) low VO2 peak (LO) - peak VO2 <52.15 mL/kg/min. Subjects of both groups underwent two exercise protocols in randomized order: moderate aerobic exercise (60% of VO2peak) following the intake of 250 mL of water (placebo protocol) or 250 mL of ED (ED protocol). During the exercise tests, values of cardiorespiratory and HRV parameters were recorded.
Significant differences were observed for the LF (normalized units) index between rest and Rec1 in HO energy and LO groups during the ED protocol. For the LF/HF ratio, significant differences were seen between rest and Rec1 in HO and LO during ED protocols.
Acute ED intake delayed heart rate recovery after exercise in subjects with low and high cardiorespiratory fitness.
有人认为，能量饮料（ED）的摄入可能会影响心血管活动。
研究 ED 摄入对不同心肺能力男性在中等有氧运动后心率变异性（HRV）和心血管恢复的急性影响。
这是一项随机、双盲、交叉、安慰剂对照研究。根据峰值摄氧量（VO2peak）值，将 28 名年轻成年人分为两组：（1）高 VO2 峰值（HO）- VO2peak > 52.15 mL/kg/min，和（2）低 VO2 峰值（LO）- peak VO2 <52.15 mL/kg/min。两组受试者均以随机顺序进行两种运动方案：中等有氧运动（60%的 VO2peak）后饮用 250 毫升水（安慰剂方案）或 250 毫升 ED（ED 方案）。在运动测试过程中，记录心肺和 HRV 参数的值。
在 ED 方案中，HO 能量组和 LO 组在休息和 Rec1 期间 LF（归一化单位）指数存在显著差异。对于 LF/HF 比值，在 ED 方案中，HO 和 LO 在休息和 Rec1 之间存在显著差异。
急性 ED 摄入延迟了心肺功能低和高的受试者在运动后的心率恢复。
