Aerobic metabolism‚ uses fats‚ proteins and carbohydrates that are oxidized and turned into carbon dioxide and water. Anaerobic metabolism‚ uses only carbohydrates and enters the fluid‚ or cytoplasm‚ of the cell and is turned into lactic acid. Aerobic exercises are running‚ biking‚ and swimming‚ whereas anaerobic exercises are sprinting‚ jumping‚ weight training. 3. My activity is considered

Introductory Activity Heart Rate (pulse) Have the students find their heart pulse on the carotid artery of the neck. Use the index and middle finger to measure the pulse. Count the number of beats for 6 seconds and add a zero to the end of that number. This number represents the heart beats per minute. The heart pulse is located on either side of the wind pipe‚ next to the voice box. Allow the students to practice measuring their pulse to determine their resting heart rate. Explain that they need

Heart Rate Anticipatory Response: Anticipatory heart rate is the rate that the heart reaches before the start of exercise. Your heart rate usually picks up as a result of the anticipatory heart-rate response‚ this happens before exercise. When thinking about exercising before actually starting‚ the nerves that release the chemicals that adjust your heart rate increase the heart rate. The body expects exercise and therefore prepares for the activity‚ increasing the amount of oxygen being delivered

Case Study 1 A&P II Age-Related Changes that Occur in the Cardiovascular System As we age‚ certain changes in the heart are inevitable. Even in the absence of disease‚ the wall of the heart thickens‚ heart rate slows‚ maximum heart rate declines‚ and the heart doesn’t pump as efficiently as it once did. Health problems‚ such as hypertension‚ coronary disease‚ congestive heart failure‚ and myocardial infraction are more common in the elderly and aggravate age- related degenerative change in the

n this study‚ the Stroop effect experiment will be carried out on matching and mismatching test. The Stroop effect experiment was named after Ridely Stroop‚ published in 1935‚ and the purpose of this experiment was to demonstrate the difference in reaction time of reading the name of the coloured words and naming the ink of the colour. Not only does it record the reaction time‚ but it also aims to measure individuals focused attention‚ learning and memory (Stroop‚ 1935). However‚ when reading through

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
