Summary Of The Effects Of Caffeine On The Heart Rate

The effects of caffeine on the heart rate

Introduction

In the everyday life, people consume a large dose of caffeine in their routines, including coffee and tea, Consumers have not knowingly consumed the caffeine without regards of its effects to their health and wellbeing. Some effects however can heighten performance, which is believed to be linked to its effects on the aerobic capacity. This aerobic capacity refers to the amount of oxygen the body can distribute to the muscles and cells, also known as VO2max. During physical activity, the amount of oxygen needed to sustain the muscles and cells are increased, which forces the heart to pump blood harder and faster (Duncker & Bache, 2008). Current studies of the effects of caffeine shows its relationship to the heart, as the consumption of

This increase in pulse rate shows its relationship between caffeine and aerobic capacity, which provide evidence to support the hypothesis that caffeine increases the pulse rate. Related studies show that caffeine consumed prior to exercise improves the aerobic endurance (Hodgson et al. 2013). This caffeine increases the adrenaline in the body, causing the heart to pump faster, increasing the heart rate. The findings of the current study contribute to the studies on caffeine as it provides knowledge of the caffeine to the heart rate, as well as its effects on the cardiovascular system such as blood pressure which can a factor to the effects of caffeine in the aerobic system. As well as, the current study provided evidence that caffeine effects shorter periods of exercise, as related studies have tested effects of caffeine on long periods of exercise. This further supports the hypothesis that caffeine increases the pulse rate and shows its relationship to other cardiovascular system which have contributed to these results, including blood pressure and blood
