RESULTS OF EXAMINATIONS (69 BOYS , AGE 14 YEARS)
Summary Results of functional exaninations are presented, which were obtained at graduated loading on a bicycle ergometer , in 69 boys , age 14 years. The boys wre divided into groups , containing untrained subjects and sports gymnastics.
Significant differences were found between the boys trained in light athletics , swimming and the untrained boys ( the control-group) , as far as the functional response is concerned.
According to several indices , as for instance PWC 170, maximum oxygen uptake and maximum minute ventilation as well as the heart rate course at submaximal loads , an increasing fitness has been found in boys practising different sports activities. The increase depended on the type of the motional activities: the fitness was only slightly higher in subjects practising sports gymnastics, it was higher in light athletes and highest in swimmers. In comparison whit an average population , the high physical fitness reached in individual indices in 14-year-old boys values , found usually in a youth population of higher age , or even in an adult population. Conditions , originating the training adaptation are discussed.
Phisical fitness of a subject may be well characterized by the value of PWC 170 and by the value of the constant calculated from three heart rate values , obtained at three submaximal loads. Similary , the fitness may be judged of on basis of a comparison of the dependence of the heart rate or minute ventilation on the oxygen uptake , at graduated load.

THE INFLUENCE OF SPORT IN HUMAN BODY
Health
Switzerland CyclistBicycles are commonly used by people seeking to improve their fitness and cardiovascular health. In this regard, bicycling is especially helpful for those with arthritis of the lower limbs and who are unable to pursue sports such as running that involve more impact to joints such as the knees. Furthermore, since cycling can be used as a form of transportation, there can be less demand for self-discipline to maintain the exercise because of the practical purpose of the activity.Cycling while seated is a relatively non-weight bearing exercise that, like swimming, does little to promote bone density. Cycling up and out of the saddle, on the other hand, does a better job by transferring more of the rider's body weight to the legs. However, excessive cycling while standing can cause knee damage. It used to be thought that cycling while standing was less energy efficient, but recent research has proven this not to be true. There is no wasted energy from cycling while standing.
Benefits
Cycling makes use of the largest muscles in the body (the Gluteus Maximus and Quadriceps) so it is good for people who are trying to lose body fat. Exercising at low intensity is better for people who want to lose weight as the body doesn't have the chance to burn fat at high work rates and will burn glycogen instead (although the body will replace the burnt glycogen by metabolising body fat as soon as it can - see Krebs cycle).Endurance cycling is an aerobic exercise, Sprint Cycling is an anaerobic exercise, however both types involve both forms of exercise to some degree and can improve cardiovascular health. One measure of cardiovascular health is VO2 max.The physical exercise gained from cycling is generally linked with increased health and well-being. According to the World Health Organisation, physical inactivity is second only to tobacco smoking as a health risk in developed countries, and this is associated with many tens of billions of dollars of healthcare costs. The WHO's report suggests that increasing physical activity is a public health 'best buy', and that cycling is a 'highly suitable activity' for this purpose. The charity Sustrans reports that investment in cycling provision can give a 20:1 return from health and other benefits. It has been estimated that, on average, approximately 20 life-years are gained from the health benefits of road bicycling for every life-year lost through injury.

INFORMATION
The influence that makes us sports are:
1. Improves breathing capacity, there by achivieng greaber amount of air and hability to capture crygen.
2. Develop the heart and circulatory sistem. Otherwise, the person has more erdurance and less tires.
3. Improving the status of the locomotor system, it provides greater stergth and flexibility and, perhaps most importantly, prevent many inyories.
4. Improves the activity of the nerveus system. In this way we have better reflexes and coordination to perfom movements.
5. Helps us to make friends.

WELCOME!
Sports have a great influence in the human body.
When you practice a lot of sports you are moving many muscles of your body.
