This study examined the acute effects of caffeine on the cardiovascular system during dynamic leg exercise. Ten trained, caffeine-naive cyclists (7 women and 3 men) were studied at rest and during bicycle ergometry before and after the ingestion of 6 mg/kg caffeine or 6 mg/kg fructose (placebo) with 250 ml of water. After consumption of caffeine or placebo, subjects either rested for 100 min (rest protocol) or rested for 45 min followed by 55 min of cycle ergometry at 65% of maximal oxygen… 

Figures and Tables from this paper

Effect of caffeine on metabolic and cardiovascular responses to submaximal exercise in lean and obese men

Caffeine activates metabolism without inducing major changes in fat/carbohydrate oxidation in lean and obese subjects, and the differences in body fat content seem not to affect the caffeine-induced effects in a submaximal exercise.


The findings indicate that caffeine at this dosage level alters cardiovascular dynamics by augmenting arterial blood pressure in moderately obese men at rest, however, it seems that taking caffeine before exercise does not cause abnormal elvations in blood pressure.

Effect of Caffeine on Hemodynamics and Autonomics Parameters in Hypertensive Women after Aerobic Exercise

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.

Effects of caffeine and high ambient temperature on haemodynamic and body temperature responses to dynamic exercise.

Caffeine-induced increases in lactate, MAP and HR during exercise suggest that this drug and high ambient temperatures increase production of muscle metabolites that cause reflex cardiovascular responses.

Caffeine ingestion alters central hemodynamics following aerobic exercise in middle-aged men

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.

Caffeine influence on blood pressure response to aerobic exercise in hypertensive subjects

It was concluded that CA not only suppresses the hypotensive response to exercise, but also provokes post-exercise hypertension.

Effect of Caffeine on Blood Pressure during Resistance Exercise in Sedentary Healthy Male

Results indicated that systolic and diastolic BP and mean arterial pressure significantly elevated following caffeine intake at rest, but no significant differences were observed after.

Effect of Caffeine on near Maximal Blood Pressure and Blood Pressure Recovery in Physically-Active, College-Aged Females

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-induced changes in cardiovascular function during resistance training.

To prevent elevated blood pressure and potential enhanced risk of heart disease, CAF intake should be monitored in at-risk men who participate in resistance training, and significant increases in heart rate, blood pressure, and rate-pressure product with acute CAF ingestion versus placebo were shown.



Effects of caffeine ingestion on body fluid balance and thermoregulation during exercise.

Caffeine ingestion under the conditions of this study does not seem to disturb body fluid balance or affect thermoregulation during exercise performance, and when compared with placebo, no significant difference in final temperature or in percent change in plasma volume were found.

Caffeine elevates blood pressure response to exercise in mild hypertensive men.

Cardiovascular responses to the combination of caffeine and mental arithmetic, cold pressor, and static exercise stressors.

The present study examined cardiovascular responses to the combination of caffeine and mental arithmetic, cold pressor, and static exercise stressors in 48 healthy males and revealed a potentiation of anxiety and anger responses to stress on the caffeine day.

Effects of caffeine on baroreflex activity in humans

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.

Evidence for an Antagonism Between Caffeine and Adenosine in the Human Cardiovascular System

The results indicate an antagonism between caffeine and adenosine in humans, which may support the suggestion that some circulatory effects of caffeine are caused by an interaction with endogenous adenosines.

Effects of caffeine ingestion on thermoregulatory and myocardial function during endurance performance.

The use of caffeine for ergogenic purposes by young athletes is a relatively safe procedure, and no pathological electrocardiographic changes occurred in either group.

Effects of caffeine ingestion on metabolism and exercise performance.

The enhanced endurance performance observed in the C Trial was likely the combined effects of caffeine on lipolysis and its positive influence on nerve impulse transmission.

Haemodynamic effects of coffee and caffeine in normal volunteers: a placebo‐controlled clinical study

It is concluded that Italian coffee and caffeine increase blood pressure via vasoconstriction.

Influence of caffeine on exercise performance in habitual caffeine users.

The results suggest that habitually high caffeine users acquire a tolerance to caffeine which reduces its effects during prolonged exercise, and to magnify the effect of caffeine, habitual users should withdraw from caffeine use for about 4 days.
