Introduction When an athlete sustains an injury while playing the sport that they love, it can have a debilitating effect. Depending on the injury, not only can they be forced to miss a significant amount of playing time (which can affect their livelihood) while they go through rehab, they also lose a huge piece of themselves. The physical part of an injury is only half the battle athletes have to face. Thoughts, feelings and spirit all contribute to sport performance, and are important parts of every athlete (Brehm, 2008). Injuries cause extreme pain, limit movements and depending on the severity, can require a large amount of time for rehab.
At any moment a police officer might be faced with a “shoot or no shoot dilemma.” During these times the body’s response system prepares the body to either fight or flee the threat. Bodies react by releasing stress hormones (adrenaline) into the blood. These hormones prepare the body for the "fight or flight response" by making the heart beat speed up and making blood vessels smaller in order to get more blood to the center of the body as opposed of the outer extremities. Smaller blood vessels and an increase in heart rate will raise the blood pressure (Baker, 2010). Heart disease is known to be a consequence of any severe stressor that triggers the “fight or flight’ responses.
When external pressure is put on the skin, the pressure of the capillaries under the skin increases causing them to occlude. If there is no relieve from the pressure for a long period of time, the tissue will become deprived of oxygen and glucose as the blood flow will be restricted. This will result in tissue necrosis (death). Everyone is different, so the time needed for a pressure sore to form will vary from person to person. The other cause of pressure sores is friction.
I have asthma so exercise is quite difficult for me as I get out of breath very quickly. Even after stopping exercise my pulse was still very high. This could be changed by doing a bit of light exercise each day nothing to hard. My body would the get use to this and in future my data could be changed. Below Is my own collected data before and after exercise: Below is Zoe’s collected data before and after exercise: The graph below shows both mine and zoe’s data together so they can be compared: You can see from the graph above that the only major difference is my pulse to Zoe’s pulse rate.
Unit 2 Acute response to exercise is short term effects that exercise has on the body. Musculoskeletal response An acute response of the musculoskeletal system during exercise includes an increase in blood supply. The short term effects on your muscles increases the temperature therefore there is more activation energy so chemical reactions are used by the musculoskeletal system and the metabolic activity increases. As the oxygen demand increases, more oxygenated blood needs to be supplied to the muscles so vasodilatation occurs so more blood can pass through the arteries. This affected me during the bleep test because vasodilation allows more oxygenated blood to travel to the actively respiring muscle tissues.
SUNDOWN TIMES STEEPLECHASE RACING There have been many reports about the value of Steeplechase Racing. Some say that this should be banned and others want it to remain. I tend to agree with banning this type of racing. Steeplechase Racing involves the horse jumping over hurdles of some kind. This can be quite dangerous and brutal for the horse and the jockey as many horses and jockeys have fallen over the hurdles and have become injured, with many of the horses having to be put down.
On the flip-side when competing in high impact sport there is a very high chance of some sort of injury occurring along the way. For example if someone dislocates their shoulder playing rugby, it is more than likely that this will trouble them in the future. In addition to this when playing contact sports, the joints that are covered in articular cartilage can be worn away at a more rapid rate. Some injuries even lead to the cartilage being taken out altogether. This is a negative effect of contact sports on the skeletal system of young people as they may well end up suffering from osteoarthritis later in life.
The reason they started to feel sick is because their bodies were diverting blood away from the stomach and using it for muscles and other organs. The reason they sweat is because of homeostasis and the need to maintain a stable body temperature as their bodies are preparing for action. Before and during the ride the adrenal glands, controlled by the endocrine system, would have kicked in. The adrenal glands secrete a fast acting hormone called adrenaline a hormone which is chemically similar to neurotransmitter. Adrenaline would also explain why the boys felt sick and sweaty because it has the same affect in a threatening situation as the sympathetic nervous system.
The consequences of not maintaining homeostasis balance may be being admitted to the hospital, a heart attack, stroke, aneurism, and possibly could lead to dying. It is very important that you watch what you eat, your weight, stress levels, and also exercise regularly to help maintain your hypertension levels to where they need to be at. There are medications that you will also be put on to help stabilize your hypertension levels if it increases and you are not able to control or maintain it on your own. Hypertension is a very serious issue and does not need to be taken lightly. You should take care of yourself and your body because your health is very
Also, chronic stress, depression and anxiety can cause lack of appetite, high blood pressure, decrease in muscle tissue, decreased bone density, lowered immunity and inflammatory responses in the body and slow would healing. These can cause eating disorders, heart attack or stroke, easily broken bones, and much more body issues. All these are negative effects that increased levels of cortisol can cause to an individual’s mind and body. The increased amount of cortisol in my body has caused me to suffer from anxiety disorder therefore I suffer from lack of appetite, high blood pressure, and it takes my body longer to heal. 2.
