To study the change of the trace elements in blood serum of volleyball athlete during high intensity training,the content of Se,Zn,Cu,Fe,Ca,Mg,Mn of 20 cases blood serum of volleyball athlete was examined by ICP AES.
The subjects consisted of untrained controls (C), volleyball players (VB) who spent about half of their training time (360 min · week-1) doing anaerobic conditioning exercises and who had a maximal oxygen uptake (
It was applied to the assessment of [ATP] and [PC] in four groups of sedentary subjects (children, and adults aged 20-35, 35-50 and over 50 years), and in a group of athletes (volleyball players).
In a group of 20 elite female handball or volleyball players, an evaluation was made of the response to a 4-month training period of cortisol, androstenedione and dehydroepiandrosterone in the saliva.
In contrast, amongst the volleyball players, stressful stimuli produced by an increase in the amount of training did not affect adrenocortical metabolism during exercise.
So far as phasic results were concerned, the main finding was a differing development of skill between imagining and non-imagining volleyball players.
