Application of Anatomical and Physiological Knowledge to Improve Performance

PHYSICAL FITNESS

Physical fitness is the capability to meet physical and physiological demands made by a sporting activity. In any chosen sport you need a lot of different parts of physical fitness to perform to the best of your ability.

STRENGTH

Strength is normally measured by the amount of weight the muscles can lift, or applying a force against a resistance during a single maximal contraction.

Examples of this are handgrip strength or the power from the leg from a vertical jump.

In the sport football strength is important in all positions. For an attacker strength in the leg is important for when they have an opportunity to shoot they have to be able to exert a reasonable amount of force on the ball to make it move with speed and power increasing the chances of a goal if the shot is on target..

For a midfield player in a football team their strength is vital for the whole of the match. Being the link between the defence and attack midfielders are involved in the game the most and have a lot of running to do. Explosive strength is something that they need greatly when starting from a static position to sprinting for the ball.

For defensive players strength is probably one of the most important assets they could have. One way in which this strength is important is when defending a ball in the air. They need strength in their legs so they can jump vertically and head the ball away

Goalkeeping, arguably the most important position on a football team requires a great deal of strength for a number of things, such as, diving in the air to save a shot or jumping in the air to catch a ball from a crossing situation.

Methods of improving strength can vary, weight training is an effective way of building up muscle strength increasing the capabilities of the body. It is important to know that concentrating on just the legs for a football player is not necessarily the best thing to do as upper body strength is also needed a great

Flexibility

Flexibility is the range of movement possible at a joint. It is an important part of fitness that we need to keep into old age. We lose flexibility as we grow older. We should always remember to warm up before competition to stretch our muscles and tendons. An example of a flexibility the sit and reach test

In football, for an attacker flexibility can be very important in the spine when jumping for a header. It is important to arch the back correctly in preparation for the thrust movement of the head and neck as contact is made with the ball. This way, power can be put on the ball, to generate speed:

For a midfield player flexibility can be when attempting to control the ball by using the chest. The back, again is arched backwards and the arms are pushed backwards to bring the chest out more, giving the ball a larger surface area to land on

A defensive player would need flexibility in the legs for tackling. Defenders legs would have to be able to move in a range of different directions to enable a better chance of taking the ball in a sliding challenge.

A goalkeeper would need flexibility in the arms, hips and legs to enable them to spread their bodies accordingly when dealing with shots. A good way of training flexibility is a ‘sit and reach’ training method in which you must try to stretch as far as you can whilst laying with your feet straight.

Muscular Endurance

Muscular Endurance is the ability of the muscle to work for long periods of time without tiring. There are two main parts of endurance that put together endurance, these are: local muscle endurance and cardiovascular endurance. Local muscular endurance is how long the actual muscles in the body can continue for before they get tired and cardiovascular endurance is how long the heart and lungs can supply oxygen around the body whilst participating in an activity. Good examples of local muscle endurance are sit-ups and chin-ups. A main factor of how good somebody’s endurance is depends a lot on body weight and fat. It can be difficult to reach and maintain a good level of fitness in the mentioned areas if you are carrying extra weight; this also applies to a good level of fitness. If your body is underweight it cannot store enough energy to keep you going. Being underweight can also mean that the body does not build muscle tone, and can cause joint injuries.

An attacker in football has to have good endurance so they can last the pace of the game and be prepared to make any runs when playing. Stamina levels in football have to be particularly good because of the pace the game is played at and the way the respiratory system works both aerobically and an aerobically.

Midfielders have to have the best endurance ability in football because they do the most running; the hamstrings and gastronomies have to be in particularly good shape to last a match and to avoid injury.

The reason defenders need endurance is because they have to keep up with any opposing players whilst under attack and if a team is constantly defending the defenders have to be in very good shape to be able to cope.

 Goalkeepers don’t particularly need endurance for running around as their job in a team requires them to stay inside the 18 yard box, however they do need to have a good level of endurance to be able to stay in a constant position of readiness for a whole match

Bent knee sit-ups are a good method of increasing muscular endurance, ...
