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.
Part II: Design a Warm-up for Your Personal Needs For each of the following, describe what you will do to prepare your body for the activity that you selected in Part 1, #1. 1. Aerobic exercise Jogging 2. Stretching (stretch all the major muscle groups used) Calf Stretch Abduction Stretch Glut stretch Standing Quadriceps stretch Adduction stretch 3. Sport-specific exercise Sprint in place Part III: Design a Cool-down for Your Personal Needs For each of the following, describe what you will do for your cool-down for the activity that you have selected.
The body receives oxygen from the lungs and transmits it to your muscles through your bloodstream. The heart controls the flow of blood throughout the body and your heart rate is a factor of that flow. Therefore when your muscles work harder and require more oxygen, your heart rate increases to meet the needs to maintain a consistent internal state, the harder you work the faster your heart pumps. The probable homeostatic responses to changes in the internal environment during exercise to the breathing rate, exercise will increase the demands on your body to supply the fuel it needs to perform. Your body’s need for oxygen will increase.
Cardiovascular system has three main functions: Transport of nutrients, oxygen and hormones to cells throughout our body and removal of metabolic wastes such as (carbon dioxide and nitrogenous wastes). Protections of the human body by while blood cells, antibodies and complement proteins that circulate in the blood and defend our body against foreign microbes and toxic. Clotting mechanisms are also present that protect the human body from blood loss after injuries. Regulation of body temperature, fluid pH and water content of
Case Study Questions: 1.) Explain the renin-angiotensin-aldosterone system. When the kidneys sense decreased profusion pressure, they try to increase this pressure by increasing blood volume through the renin-angiotension-aldosterone system. Once the decreased pressure is sensed renin is released, which increases conversion of angiotension to angiotension I. Angiotension I is in turn converted to angiotension II by the angiontension converting enzyme (ACE). Angiotension II causes vasoconstriction, which raises the blood pressure.
BIOS 255 Week 4 Lab: #7 Effect of Exercise on Arterial Pressure and Vascular Resistance LABORATORY REPORT Activity 7: Effect of Exercise on Arterial Pressure and Vascular Resistance PREDICTIONS 1. During exercise: MAP will increase 2. During exercise: CO will increase 3: During exercise: SVR will decrease MATERIALS AND METHODS 1. Dependent Variable: heart rate (HR), stroke volume (SV), blood pressure (BP) 2. Independent Variable: level of activity 3.
Cardiovascular endurance is important because you heart controls the oxygen flow to your muscles directly affecting performance The type of athlete that requires good cardiovascular endurance is similar to muscular endurance; an example would be a footballer. Cardiovascular endurances can be improved as the heart is a muscle, to test cardiovascular endurance you could do the bleep test. The bleep test requires the participant to run a distance keeping in time with a recorded cd. Similar to the abdominal curl test the bleep test is completed when the participant can no longer keep up with the CD. Body Composition Body composition refers to 3 different types or shapes of body endomorph, ectomorph and mesomorph.
This single metabolic fact accounts for the profound changes in not only respiration, but also in cardiac and circulatory physiology during exercise. Increased oxygen supply is provided by increases in both arterial oxygen delivery and tissue oxygen extraction; at the same time there is increased carbon dioxide transport on the venous side. The need for increased gas exchange by exercising muscles leads to the following general physiologic
The body’s metabolic rate is increased as its need for energy is increased, and the body becomes more resourceful. Muscle tone and muscle mass increase after the muscles tear and reconstruct themselves. In addition to improved muscle tone and muscle mass, there are other effects of exercise for physical disease control and/or prevention. A person’s entire body system, including all the ***** 2 body parts, is in continuous movement when exercising. The cardiovascular (heart), circulatory, and pulmonary (lungs) systems probably benefit the most from routinely
Athletic Training deals with prevention; care and rehabilitation of injuries to people that are physically active. Exercise and Sports Psychology deals with the importance of body movement and the effect the mind has on it. Lastly Sports Nutrition deals with food and good eating habits (4). Athletic Training Athletic Training first started in the 1900’s-1925 in the United States. Athletic Training is the health profession dealing with injury prevention, care, and rehabilitation of injuries to people who are physically active on a regular basis.
