The Cardiovascular System's Response to Acute Exercise

The cardiovascular system's response to acute exercise can be discussed in many ways. It has plenty of response's to this exercise. This is the system that circulates blood and lymph through the body, consisting of the heart, blood, lymph and the lymphatic vessels and glands. A response to this exercise may be the Anticipatory heart rate.  The Anticipatory Response is when the heart rate increases at the beginning of exercise. The heart rate can be changed by chemicals by neurotransmitters , called adrenaline and nor adrenaline  which are released and found in the brain. These neurotransmitters are the chemicals found and released from the brain which allow an impulse from one nerve cell to pass to another nerve cell. These chemicals tell the heart to get ready for exercise therefore  there is an increase in beats per minute, heart rate increases. By increasing our heart rate our body begins to supply oxygen and nutrients for our working muscles.  Another response ...

The Respiratory System's Response to Acute Exercise

The respiratory system consists of the respiratory muscles, lungs and everything else to do with breathing. The two main responses to acute exercise are increased breathing rate and an increase in tidal volume . During Acute exercise there is a response from the respiratory system also, it responds in ways like, breathing rate increasing such as a neural response, and chemical control and also the increase of tidal volume. When your breathing rate increases we breath more frequently and deeper, this insures that there is more oxygen getting to the muscles through the blood which is pumped faster around the body. The muscles need oxygen to work effectively and efficiently. The muscles are used more to exhale as they help and ensure that air is squeezed out of the lungs as it carries waste products like carbon dioxide and nitrogen are carried out of the body as they aren't used and need to be replaced with more oxygen quicker, depending on the amount of exercise you are doing at...

The Musculoskeletal System's Response to Acute Exercise

The responses to acute exercise for the musculoskeletal system can be described in many ways. The skeletal system have many responses to acute exercise. It can have an increased Osteoblast activity at the points of stress, there is also an increase of synovial fluid production, this means that more synovial fluid is released into the joints also indicating there is more cushion between the joints. this is good as it prevents them from rubbing together causing friction. Another response to this is that there is an increase in blood supply, this is also good as it allows more movement from the muscles and bones. There is also an increased blood flow to the ligaments and tendons, this allows a greater range of movement and means there is a less likely hood of a tear due to the increased elasticity. The capillaries dilate to allow more oxygen  to be delivered to the working muscles. This is also good as the muscles need specific nutrients to help them function a...

The Energy Systems' Response to Acute Exercise

What is ATP? ATP is a molecule that stores and releases chemical energy for use in body cells. ATP stands for Adenosine triphosphate. It is a high energy compound. It is produced from glucose, and other energy sources when they are needed. those energy sources can be sored in the liver, muscles, or as fat tissue. The body transfers stored chemical energy to mechanical energy, and it does this by the breakdown of Adenosine and Triphosphate. This is ATP. It is released by the breaking down of the phosphates it releases energy for movement. Energy systems are used to break down ATP and then remote ATP to be broken down again. This process begins over and over again. The problem is that the muscles only store a small amount of energy compound (ATP) and it is limited to around 2 seconds wroth of energy. Energy systems are then used to remake the ATP for small bursts of energy, this is important for athletes like marathon ...
