If we take breathing as a taxonomic criterion, sports may be divided in two large teams:
1. The first one consists of all of the sports that use the strategy of respiratory cease or blocking. The most common among these are force sports similar to athletic weight throwing, weightlifting, body constructing, gymnastics etc. In brief, we would say that right here the anaerobic excessive is anxious – the one which imposes apnea (blocking the thorax and respiration). The main advantage of diaphragm blocking is the rising, for the moment, of the explosive force of the sportsman. An increase in execution pace for optimum pressure efforts has also been observed. The classic example is the snatch of weightlifting in which force and velocity are concurrently implied on the premise of respiratory blocking.
This respiratory blocking, inevitable in the above-mentioned sports activities, has also some disadvantages. Amongst these we might mention excessive pressure values within the thorax, stomach and skull, excessive pressure on blood vessels with low feed-back by way of the veins etc. Thus, because of the rising of stress inside the eyes the aggravation of earlier brief-sightedness is possible. Also, within the inferior limbs, varicose veins can either appear or worsen. Effort in completely anaerobic circumstances will increase rigidity both in the blood vessels and within the muscles.
2. The second massive group is the certainly one of sports activities that don’t use respiratory stop. Right here we enter the realm of purely cardio effort. The typical examples are operating races, swimming, biking etc. – usually efforts on lengthy and very long distances. In these events the muscular power implied is little – medium at most – the stress affecting the cardiovascular component and leading to increased cardiac frequency and pulmonary ventilation.
There’s additionally a third class – mixed sports, each aerobic and anaerobic, during which the 2 techniques alternate. This is the case of sports games, contact sports, rhythm breaking in medium distance operating races, etc. Within the case of health, as both forms of effort – cardio and anaerobic – are present, apnea, in addition to effort without respiratory blockage, is used. So far as correct respiration is worried, there is a common rule stating that one should breath out throughout the most tough part of the motion (the optimistic or concentric course) and breath in throughout come-again (the adverse or eccentric course). Within these programs, we will have or not have a respiratory cease/ blockage. If we now have it, it’ll happen on the crucial level of the course.
One other breathing rule is the one which takes into consideration the dilatation of the thorax. In this case, breathing in is completed on the course which allows thorax enlargement, and breathing out on the movement that contracts it. In both circumstances, breathing in is done by way of the nose – with a view to filter and warm up the air stream and breathing out is finished by the mouth with a view to be faster and extra efficient.
It is interesting to know that the ‘shouting’ that we hear in lots of weightlifting coaching periods or contests, is actually the sound of forced breathing out.
