Differences in the levels of physiologicalbiochemical responses during physical exercise involving the lower and upper extremities in judo competitors

Abstract

Scientific discoveries, the development of research techniques as well as long term observations allowed selection and hierarchization of the groups of factors determining the level of physical capacity. The great success of the past years was the development of the methods of blood lactate concentration assay, reflecting the anaerobic metabolic processes that occur during intensive physical work. The unquestioned success of these years was the measurement of maximal oxygen uptake (VO2max). This is an integrated indicator determining physical capacity. The amount of oxygen that can be consumed by the human body during maximal effort is an aggregate indicator of the oxygen supply function and oxygen consumption in the tissues. The respiratory system, the cardiovascular system, blood morphotic elements (red blood cells) with their main component – haemoglobin, are engaged in oxygen transport. Generally, it is accepted that the higher the competitor’s VO2max value is, the more they are capable of intensive and sustained exercise performance and the better
