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 study was performed to examine markers related to health‚ the incidence of reported side effects and the

The Effects of Secondary Plant Compounds on Lumbriculus Variegatus Heart Rate Introduction Blackworms (Lumbriculus variegatus) were used in this experiment to study the effects of secondary plant compounds‚ chemical compounds produced by plants that are not part of the general metabolism‚ on pulse rate. Secondary plant compounds act as defense mechanisms which reduce or eliminate consumption of some plant species or even attract predators. These compounds are not essential to the plant but often

The affect of psychological stress on the heart rate. Introduction: The human body is incredible machinery that can adjust to stressful situations and react in a “fight-or flight” manner by temporarily shutting off nonessential‚ at the moment‚ immune and digestive systems. When the body is ready for a challenge‚ heart rate increases‚ blood pressure rises and glucose production intensifies to supply large amounts of energy. These metabolic changes are caused by release of stress hormones (catecholamine

is among the top preventable risk factors of heart disease amongst many other health problems. Coronary heart disease and strokes are the primary types of cardiovascular disease caused by smoking. They rank as the first and third leading causes of death in the United States. More than 61 million Americans suffer from some form of cardiovascular disease. Smoking increases your risk for high blood pressure‚ coronary heart disease‚ stroke‚ congestive heart failure‚ and aneurysms to name a few. More

Every day your heart pumps blood through a vast network of blood vessels around and around your body‚ delivering food and oxygen to cells and removing waste. The pulse (heart rate) is the number of times a person’s heart beats per minute (bpm). The pulse is a rhythmical throbbing of the arteries as blood is propelled through them‚ typically felt in the wrists or neck. Your resting heart rate occurs when you become relaxed or comfortable. These are shown when sitting or lying down. The ability to

Callum Bourke Describe the long term effects of exercise on the Muskoskeletal system and energy systems. (P3) Describe the long term effects of exercise on the cardiovascular and respiratory systems. (P4) Cardiovascular System Cardiac Hypertrophy The heart increases in size and volume; this allows more blood to enter the heart allowing a greater amount of oxygenated blood to be pumped to the working muscles. To withstand the large amount of blood‚ the left ventricle becomes thicker

Report The Effects of Exercise on the Cardiovascular System Introduction Exercise has a major impact on the cardiovascular system and its efficiency in the human body. There are many concepts which need to be examined to understand exercise and the cardiovascular system‚ such as systolic and diastolic blood pressure‚ cardiac output‚ total peripheral resistance‚ and physiological pathways. According to the European Journal of Cardiovascular Prevention and Rehabilitation‚ exercise provides a change

The Human Heart Rate Aim: To study changes in the rate of the human heartbeat. Introduction: Blood is sent pulsing through the body’s veins‚ arteries and capillaries with each beat of the heart. The circulation of blood through the body delivers oxygen and food to the cells and removes wastes. The cells cannot survive if circulation stops for even a small amount of time. With an increase in body movement there is an increase in the cell’s energy use and the heart rate must increase to pump

Nikul Patel DS13 25-12-03 Effects of exercise on cardiac output (For results see graph paper) Analysis After the initial period of rest in both girls and boys heart rates rose slightly with light exercise (walking)‚ and then fell again slightly back towards the original resting point. Then during the period of anticipation of exercise the males heart rate rose by a further 1 beat per 6 seconds‚ whereas the females took a dramatic leap‚ and rose by 3.5 beats per 6 seconds‚ or 35 beats per minute
