Physical Fitness in sports.

Introduction

Physical Fitness is the key to succeeding in Sport. In Gaelic Football Fitness is an essential part of the sport. Fitness can be broken down into two parts, physical fitness and motor fitness. There are many different components of Physical Fitness; there is speed, endurance, flexibility and body composition. To be victorious in sport motor fitness is also essential at the highest level, this consists of agility, balance, coordination power and reaction time. In Gaelic Football these components are vital. In Gaelic Football there are different positions on the field, goalkeeper, full and halfbacks, midfielders, full and half forwards. The Players in these positions need different physical motor fitness, because of their different tasks on the pitch. Physical Fitness Components ENDURANCE This is the capacity to direct movement or effort over a period of time. Muscular Endurance is the ability of a muscle or group of muscles to carry out movements without tiring for a period of time. STRENGTH The force applied by a muscle or group of muscles against a resistance during a single maximal muscle contraction. FLEXIBILITY The ability to move all our joints through their full range of movement, the type of joint and muscle attachment affects it. ...read more.

Reaction time can be vital at times to half forwards as reaction time can win matches, for example if a defender makes a mistake and the half forward ceases on the opportunity and scores a point to win the match. FULL FORWARDS Endurance is important to full forwards, but it is not vital as speed is more important to them as they need to get out in front of the defender to get the ball. Flexibility is important as full forwards need to twist and turn to get away from defenders to position themselves to score. Body composition is important because they need to be quick and carrying, as little body fat as possible as it will slow you down. Motor fitness components also are important for full forwards to play well at the highest level, agility is important for them to perform movements with balance, for example selling a dummy to a defender, balance is important to perform this movement. Coordination is vital to a sequence of precise movements for example catching the football, turning and taking it past a defender and shooting. Power is essential in taking the ball past defenders for full forwards. ...read more.

Conclusion

The increase in body and muscle temperature causes an increase in transportation of the enzymes required for energy systems and muscle contraction. It mobilizes the oxidative energy sources so that it is easier to switch to aerobic energy production. This is achieved by increases in the heart and respiratory rates. Warm ups make us more alert because the speed of nerve impulse contraction has increased. Also, the increase in body/muscle temperature decreases blood viscosity (resistance of blood flow), which improves blood flow to working muscles, and increases the dissociation of oxygen from haemoglobin in muscle tissues. A decrease in OBLA (onset of blood lactic acid.) takes place because of the early arrival of anaerobic activity when a warm up is not carried out. The cool down also has physiological effects on the vascular system; it keeps the metabolic rate elevated, which slowly decreases heart rate and respiration. Performing a cool down maintains respiratory pumps, which prevent blood pooling in veins, which can happen if exercise is stopped abruptly, and maintain venous return. It also maintains stroke volume and cardiac output and keeps capillaries dilated to flush muscles with oxygenated blood, this then increases the removal of blood and muscle lactic acid and carbon dioxide. The cool down also limits the effects of DOMS (delayed onset of muscle soreness), which can cause tender and painful muscles, it is most likely to come following eccentric contractions. ...read more.

  1. Describe the different sports massage techniques

    Massage can be used before, during and after competing. For example an athlete could go to a therapist just before a big race for a massage to loosen up the muscles, relax if stressed, increase blood circulation so that to prevent injury during or after the event and to get rid of any lactic acid that had built up in the week from training.

    Carpal heads have a rectangular surface. They are convex and flattened laterally; it articulates with the proximal phalanx; it is also longer in some parts of it diameters than others. On either side of the head is a tubercle for the attachment of the lateral ligament of the metacarpo-phalangeal joint (joint of the metacarpal and phalange).

    These weaknesses could be improved by training the fitness component power. Training this specific fitness component will improve their dodging performance by developing their speed, thus affecting their agility.

  1. Extrinsic injury risk factors

    For example, in racket sports the action of serving and smashing can lead to a relative imbalance of specific muscles at the shoulder joint (those that rotate the arm inwards) that place the joint at a massively increased risk of injury.

  2. What are the Affects of Warming Up and Cooling Down?

    Warming up before and after resistance training is very important. To prepare the body for higher levels of effort, as well as a focused mind, a warm up prior to training is vital. Some light aerobic activity gets the blood flowing to the muscles, and some stretches loosen the joints.
