This affected me during the bleep test because vasodilation allows more oxygenated blood to travel to the actively respiring muscle tissues. Other acute responses which occur to the musculoskeletal system during exercise include an increase in muscle pliability. If your muscles get warmer because of the contraction temperature is going to rise this makes them more pliable and reduces the risk of injury. Pliability is the stretchiness of the muscles. There is also an increase in the synovial fluid at the joint.
A disadvantage of this system is the by product which is lactic acid which makes the muscles sore. A positive of this energy system is also that it can be done both aerobically and anaerobically. After about five minutes of exercise, Aerobic Glycolysis is the dominant energy system. Aerobic Glycolysis produces energy by breaking down muscle and liver glycogen stores with oxygen present. Because oxygen is present when this system is in use, there is no build up of lactic acid.
Restate your predictions that were correct and give data from your experiment that support them. Restate your predictions that were not correct and correct them, giving supporting data from your experiment that supports your corrections. During exercise HR, SV, and CO will all increase due to the increased demand of oxygen needed throughout the body as well as the increased pumping action of the heart having to work faster to get blood to the tissues during exercise Application 1. We measured the stroke volume of the left ventricle. What was the average stroke volume of the right ventricle at rest and
We all know that exercise can sustain and improve our health, which is necessary for living a life of wellness, but what is not always known is how exercise can affect other aspects of our lives. Exercise is not only physical, it is also psychological. Exercise can do more for a person than just help them lose a few pounds, or maintain a healthy weight. Exercise controls weight. Most weight loss programs will not work without an exercise routine along with a structured diet plan.
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.
To accomplish this, the stretch-shortening cycle is emphasised – exercises such as bounding, leaping and hopping are utilised. The reason behind this is to improve neural adaptations such as; increased activation of motor units without the hypertrophy associated with generic strength training (Saunders, 2006). 2. Altitude Exposure – it is widely believed that exposure to altitude can enhance an athlete’s performance at sea-level. Local muscular adaptations coupled with haematological changes form the basis of this common belief.
There is no end to the importance of oxygen in the human body. Human lives depend on oxygen for life, more than they depend on water or food for sustenance. Our body’s energy is created by oxygen, and without a constant flow of oxygen in our bodies it only takes mere moments of oxygen deprivation for our bodies to begin to shut down. Many understand that oxygen is a vital part of sustaining life, but many do not fully understand that oxygen affects our brain function, nervous system, and even mental clarity. An aviation website that I came across states that the human body must have oxygen to convert fuel (the carbohydrates, fats, and proteins in our diet) into heat, energy, and life.
It can be just simple exercise that is easily integrated into your everyday daily routine. Health is a major part of your life and simple changes to your lifestyle and choices can make a massive difference to your overall health. The overall health improvement will leave you with more energy and help your concentration, which will make day to day tasks easier and more enjoyable to complete as you won’t feel drained by the end of it. (Gill Jenkins, 2010) Physical health Physical health is how your body works and is assessed like a machine by levels of fitness, the better your fitness, the better physical health you have and the better your body will work, it will be more efficient. There are many things that effect physical health within your body; the cardiovascular system which is all about heart strength, cholesterol and blood pressure; the respiratory system, how fitness effects your breathing and the oxygen getting to your muscles and organs; skeletal system and how fitness effects your bones, the strength of them and the condition of the bones; Weight control which effects most of the above factors and a main benefit of being healthy as weight can have a massive effect negatively or positively on your overall health.
Lastly, exercise increases macrophage production, salivary immunoglobulin A, and increase immune cell circulation improving the function of the immune system. Psychologically, they diminish anxiety and depression, control stress and minimize its negative effects on the body, improve self-esteem, self-concept, and body image, and improve cognition and problem solving. There are two types of fitness, aerobic fitness and muscular fitness, with their own benefits. Aerobic fitness pushes your body and forces it to adapt to adapt to the overload that the exercise is causing when trying to complete continuous tasks. This will later enable you to participate in harder workouts and exercise in the future.
Muscular and cardiovascular endurance are improved with aerobic exercises. Aerobic exercises allows me to go further with less effort. When I exercise aerobically my body is able to supply oxygen to the process of burning fuel it has stored, this is like burning fat for fuel. Some examples of aerobic exercises include : swimming , cycling , brisk walking , jogging , and aerobics classes. Aerobic exercising should only be done for twenty minutes at a time.
