Caffeine is a stimulant of the central nervous system (cns), the cardiac muscle (increases heart rate), and respiratory system (relaxes air passages permitting improved breathing, and allows some muscles to contract more easily). The magnitude of coffee-induced thermogenesis and the influence of coffee ingestion on substrate oxidation were investigated in 10 lean and 10 obese women, over two 24-h periods in a respiratory chamber. The purpose of this research was to investigate the effects of exercise capacity, heart rate recovery and heart rate variability after high-intensity exercise on caffeine concentration of energy drink in conclusion, edgⅱ showed the significant increase of exercise exhaustion time more than con .

In a study of the intrarenal mechanisms responsible for the natriuretic effect of caffeine, the renal secretion of sodium increased, and the glomerular filtration rate remained the same, suggesting that diminished fractional sodium reabsorption, both in the proximal and distal tubule of the nephron, contributes to the natriuretic effect of caffeine. Caffeine raises blood glucose levels by influencing the regulation of cellular respiration (breakdown of glucose to energy), glycogen metabolism and fatty acid metabolism so to understand how caffeine works, a basic understanding of the regulation of cellular respiration, glycogen metabolism and fatty acid metabolism are necessary. Caffeine can cause insomnia, nervousness and restlessness, stomach irritation, nausea and vomiting, increased heart rate and respiration, and other side effects.

The effect of caffeine on aerobic performance this student studied: university of sydney - biol1008 - human biology caffeine has been observed to possess a similar molecular structure to naturally occurring ‘adenosine’ molecules found in our bodies which allow cellular respiration and energy production (cao, etal, 2015). Any modest increase in breathing rate was attributed to caffeine’s secondary effect on the central nervous system, rather than a direct effect on the respiratory system (chapman r & stager jm, caffeine stimulates ventilation in athletes with exercise-induced hypoxemia, 2008). Despite there being strong evidence indicating caffeine's positive effects on the pulmonary system and lack of effects on heart rate, collectively the research remains inconclusive on the topics and, therefore, more experimental studies must be conducted.

In addition, during their training bouts and in competition many athletes use heart rate monitors as an indicator of their optimal pace, therefore the effect of caffeine on heart rate could be of great importance to the athlete.
