Background Impaired autonomic recovery of heart rate (HR) following exercise is associated with an increased risk of sudden death. Caffeine, a potent stimulator of catecholamine release, has been shown to augment blood pressure (BP) and sympathetic nerve activity; however, whether caffeine alters autonomic function after a bout of exercise bout remains unclear. Methods In a randomized, crossover study, 18 healthy individuals (26 ± 1 years; 23.9 ± 0.8 kg·m−2) ingested caffeine (400 mg) or… 
Caffeine affects autonomic control of heart rate and blood pressure recovery after aerobic exercise in young adults: a crossover study
TLDR
Caffeine was shown to be capable of delaying parasympathetic recovery but did not influence the behavior of the respiratory rate, oxygen saturation or frequency-domain HRV indices.
Caffeine slows heart rate autonomic recovery following strength exercise in healthy subjects.
TLDR
CAF protocol delayed parasympathetic regulation of heart rhythm following exercise, slowing recovery of HR, blood pressure and HRV indices after exercise, and in general, CAF impaired recovery ofHRV after resistance exercise.
Caffeine slows heart rate autonomic recovery following strength exercise in healthy subjects.
TLDR
CAF protocol delayed parasympathetic regulation of heart rhythm following exercise, slowing recovery of HR, blood pressure and HRV indices after exercise, and in general, CAF impaired recovery ofHRV after resistance exercise.
Caffeine ingestion alters central hemodynamics following aerobic exercise in middle-aged men.
TLDR
In healthy and active middle-aged men, pre-ex exercise caffeine ingestion led to higher central and peripheral systolic blood pressures, PWV and AIx at 30 min post-exercise, indicating an increased left ventricular workload which may have implications for cardiovascular event risk.
Involvement of Cardiorespiratory Capacity on the Acute Effects of Caffeine on Autonomic Recovery
TLDR
The acute effects of caffeine on heart rate (HR) autonomic control recovery following moderate aerobic exercise in males with different cardiorespiratory capacities was evaluated.
Effect of Caffeine on Hemodynamics and Autonomics Parameters in Hypertensive Women after Aerobic Exercise
TLDR
It can be suggested that the consumption of caffeine increased the cardiac sympathetic activity with resulting increase of systolic arterial blood pressure after aerobic exercise, which could be related to a possible hypertensive reaction in hypertensive middle-aged women.
The effects of varying doses of caffeine on cardiac parasympathetic reactivation following an acute bout of anaerobic exercise in recreational athletes
TLDR
Caffeine ingestion increases resting cardiac autonomic modulation and accelerates post-exercise autonomic recovery after a bout of anaerobic exercise in recreationally active young men.
Effect of Caffeine on near Maximal Blood Pressure and Blood Pressure Recovery in Physically-Active, College-Aged Females
TLDR
While caffeine consumption did not significantly affect maximal blood pressure, it did affect active and passive recovery time following vigorous intensity exercise in physically active females and exercise endurance also improved after consuming caffeine in this population.
Caffeine increases performance and leads to a cardioprotective effect during intense exercise in cyclists
TLDR
Evidence that acute caffeine intake (6 mg∙kg−1) increased performance (time-trial) and demonstrated a relevant cardioprotective effect, through increased vagal tone is provided.
Effects of Different Doses of Caffeinated Coffee on Muscular Endurance, Cognitive Performance, and Cardiac Autonomic Modulation in Caffeine Naive Female Athletes
TLDR
In conclusion, ingesting caffeinated coffee improved lower body muscular endurance and cognitive performance, while not adversely affecting cardiac autonomic function.

Autonomic contribution to heart rate recovery from exercise in humans.
TLDR
The exponential character of the cardiodeceleration seen after peak exercise appears to be an intrinsic property of the circulation because it occurred under each experimental condition.
Caffeine attenuates early post-exercise hypotension in middle-aged subjects.
TLDR
It is suggested that endogenous adenosine contributes to early hypotension after exercise in healthy middle-aged subjects and underscore the importance of caffeine abstinence if BP or HR immediately after exercise is used to infer cardiovascular risk.
Effects of caffeine on blood pressure response during exercise in normotensive healthy young men.
TLDR
Data indicate that caffeine increases BP additively during submaximal exercise and may cause excessive BP responses at maximal exercise for some individuals, and the pressor effects of caffeine appear to be due to increasing vascular resistance rather than cardiac output.
Effects of caffeine on baroreflex activity in humans
TLDR
It is indicated that single but not multiple caffeine administration inhibits baroreflex activation in normotensive volunteers and this could contribute to the acute hemodynamic effects of caffeine.
Acute effects of caffeine on heart rate variability.
TLDR
The present study sought to determine the effect of acute caffeine ingestion on PNSA in nonhabitual caffeine users by assessing heart rate variability (HRV), a simple, noninvasive method of assessing cardiac PNSA.
Acute caffeine intake influences central more than peripheral blood pressure in young adults.
TLDR
Acute caffeine intake significantly increases central BP and large artery waveform transmission and diminishes pressure amplification in healthy adults, and the effects of caffeine on BP may be significantly underestimated by measurement of BP at the brachial artery.
Influence of caffeine on heart rate variability in patients with long-standing type 1 diabetes.
OBJECTIVE The effect of caffeine on cardiovascular health remains controversial. Patients with long-standing type 1 diabetes are at risk of autonomic failure and sudden cardiac death. We investigated
Plasma norepinephrine and heart rate dynamics during recovery from submaximal exercise in man
TLDR
In the 1st min of recovery, independent of the exercise intensity, the adjustment of HR appears to have been due mainly to the prompt restoration of vagal tone and the further decrease in HR toward the resting value could then be attributed to the return of SNA to the pre-exercise level.
Metabolic and cardiovascular responses to exercise with caffeine.
TLDR
The effect of caffeine on circulation and metabolism was studied during a discontinuous maximal oxygen uptake (VO2 max) test on a bicycle ergometer and there were no other statistically significant changes in metabolic and cardiovascular variables during either submaximal or maximal exercise.
Autonomic neural control of heart rate during dynamic exercise: revisited
TLDR
Increases in exercise workload‐related HR are not caused by a total withdrawal of the PSNS followed by an increase in sympathetic tone; reciprocal antagonism is key to the transition from vagal to sympathetic dominance, and resetting of the arterial baroreflex causes immediate exercise‐onset reflexive increases in HR.
