The Effect of Caffeine on Heart Rate

Effect of caffeine on heart rate The purpose of this experiment was to test the effect of caffeine on Daphinia's heart rate. Hypothesis: My prediction for this experiment is that as caffeine is a stimulant that increases the activity of the nervous system, the increase in Daphinia caffeine increases the heart rate. Equipment, equipment used for this experiment are as follows.

In this experiment we will examine the influence of various concentrations of caffeine on Hill's heart rate. In this experiment, Daphnia is considered a human substitute to study the influence of chemical substances on the heartbeat of living beings. Heart rate is the frequency of cardiac contraction during the complete cardiac cycle. The average heart rate of a person is 72 times per minute. However, heart rate may change due to changes in the physical system such as stress, elevated body temperature, ingestion of specific chemical substances. Because caffeine intake is also thought to increase heart rate, experiments were done to test its effectiveness.

Resistance to specific physiological effects of caffeine may occur in humans. This is the effect of caffeine on blood pressure, heart rate, diuretic, plasma adrenergic and norepinephrine concentrations, and renin activity. Tolerance error usually occurs within several days. Resistance to specific subjective effects of caffeine such as stress anxiety, jitter, stress, strength of drug effect, etc. has been demonstrated. In contrast, the resistance to caffeine to improve arithmetic skills is documented, but evidence for resistance to caffeine-induced arousal and arousal ability is limited. These effects are not related to the tolerance of cerebral energy metabolism to caffeine; in animal studies acute administration of 10 mg / kg caffeine is related to whether the rats were exposed to caffeine every day or exposed to physiology But caused the same increase in metabolism. 15 days saline treatment
