The Effect of Exercise on Heart Rate The aim of this investigation is to find out how different types of exercise can affect my heart rate. To measure and record my heart rate‚ I am going to undergo an experimental test. I am going to do 3 different types of exercise: walking‚ light jog and lastly hard running. First‚ I will draw out a table to record my results‚ and then I will measure my resting heart rate for one minute. To make the experiment as accurate as possible‚ I will

selecting variables In this lab‚ we will be studying the difference of heart rate between boys and girls. There are many things that can increase heart rate‚ such as exercise‚ drinking coffee‚ taking certain pills‚ drinking an energy drink‚ feeling a strong emotion‚ etc. I have chosen to use exercise as a means of increasing the heart rate of my subjects‚ more precisely‚ 20 sit-ups. There are many reasons why your heart rate increases when you exercise‚ the most important one being that your muscles

Triphosphate (ATP)‚ which gives them the energy they need to perform. In this experiment‚ creatine is added to water and its effects on Daphnia is tested. By observing the heart rate‚ one can determine if the creatine increases or decreases heart rate. Heart rate was chosen to be measured because one can then see how creatine affects the heart. If it is unhealthy for the Daphnia‚ it could potentially be unhealthy for humans. “Long-term safety of creatine supplementation has been questioned. This retrospective

Literature Review The human heart is a very complicated organ‚ with the main purpose to pump life sustaining blood throughout the human body. It also supplies oxygen and nutrients to all areas and clears harmful waste from the body. The heart is made up of cardiac muscle which beats on its own. According to the article ‘heart ‘which was written by The National Geographic the heart will slow down or speed up depending on how the body is being used. This is done by nerve signals which are being

drinks‚ such as coffee‚ tea and cola. Caffeine is naturally present in the leaves and seeds of a variety of plants. Consuming caffeine has significant physiological effects on your body--one being its direct effect on your heart rate. Features Once consumed‚ caffeine enters your blood from the stomach and small intestine and begins to stimulate your central nervous system. Caffeine stimulates receptors located in cells within your heart to increase your heart rate. Effects of this stimulation speed

The hypotheses stated that both drug were depressant drugs thus meaning that heart rate‚ and along with it‚ metabolism. The hypotheses are‚ in fact‚ true statements that can be backed with the data collected. The initial heart rate before the drug‚ hemp was applied‚ was 216 BPM. The final heart rate‚ with the drug was 132 BPM. That is a change by -84 BPM. This proves that hemp lowered the heart rate of the

Heart Rate Experiment Introduction: The heart rate measures the contractions of your heart and is a requirement for life. The heart uses four chambers. The right and left-lower chambers are called ventricles‚ and right and left-upper chambers are called atria. These four chambers complete two cycles that replenish the tissues with oxygen and get oxygen from our lungs. The heart rate is measured in beats/ minute and a “beat” is when the lower chambers are (two ventricles) contract. This

effects of caffeine‚ alcohol and environment on Daphnia Magna. ABSTRACT In this experiment daphnia magna a semitransparent fresh water crustacean‚ are used to study the effects of water‚ alcohol and caffeine on heart rate. Daphnia was placed on a clean deep well slide. This was placed under the microscope and brought into focus on the best objective and light contrast. The heart rate was observed and counted within 15seconds and recorded on a table. Introduction Daphnia magna is
