Identify and justify the key components of fitness.

Extracts from this document...


IDENTIFY AND JUSTIFY THE KEY COMPONENTS OF FITNESS Fitness is the ability to cope effectively with the stresses of everyday life; it helps contribute to an overall healthy lifestyle. Fitness is made up of components, which can be divided into health related components, and skill related components. Health related fitness could benefit everyone to a certain degree as each component is contributing towards a healthier body. The components which help to do this are; aerobic capacity, flexibility, strength and body composition. Skill related components are more dedicated to sport performers who try to develop these skills through training. Skill related components include power, speed, reaction time, balance, agility and coordination. Health related components Aerobic capacity - This is the maximum amount of oxygen that can be taken in and used by the body during prolonged periods of participation in that activity. In football this is used through out the game as the body is usually always on the move, and so the cardiac and vascular system must be fit enough to cope with the gaseous exchange. Flexibility - This is the range of movement around a joint and depends on the stretch allowed by the ligaments and tendons surrounding the joint. Being flexible helps increase your performance and limits injury risk as stiffness is decreased around the joint area. In football keepers need to be very flexible in being able to get down low shots and when stretching themselves to make a diving save. ...read more.


An example is when a ball is coming towards you at speed you interpret the information as the ball is coming towards you to coordinate your body to stop the ball and then pass. Power is used all the time in football but off different forces. Depending on where you want the ball to go will determine how much power you will need to generate to the ball. An example is if you are in your own half and want to pass a 50-yard ball up field to your team mate, you will follow through the ball hard to generate more power for the ball to get 50 yards. If you are looking to pass the ball 10 yards you will not be looking to follow through the ball hard, but instead be giving the ball a gentle push so it has less power as it travels along the pitch. Force is created by direction applied to it, the position of the application of the force and by the size of the lever. The lever is the draw back of the leg and then the follow through, the longer the level the greater the change in momentum. Agility is used in football to twist and turn in sudden directions usually to either beat a player when dribbling or making movement in the box before a cross. ...read more.


The warm up increases the number of electrical impulses emitted from the central nervous system. These electrical impulses begins at the brain and is transmitted to the muscles contracting via the spinal cord and by nerve cells call motor neurones. So the more electrical impulses sent out the faster the muscle will contract. e like this b4 give me more says: For any sports performer a good vascual system is crucial if the performer is to perform to their best of their abilities. The vascual system delivers oxygen and food supplies to the working muscles and to remove waste products such as carbon dioxide. The blood carries vital ingredients needed for the muscles to work and the blood vessels form a closed circulatory network, allowing distribution of blood to all cells. Join a warm up or during exercise the distribution of blood around the body changes and up to 85 percent of total cardiac out put goes to the working muscles. AS FAST AS FCUK(r) - I never new love like this b4 give me more says: The warm up increases the elasticity of the arterial walls therefore helping the arteries to withstand greater fluctuations in blood pressure. The number of capillaries at the lungs and skeletal muscle increases, helping to improve the rate of gaseous exchange. After the blood goes out of the capillaries it moves in to the venules. The venules them decease in number and turn in to veins meaning that more blood can be carried back to the heart ready for more blood to be pumped back to working muscles again. ...read more.
