Functional diagnostics is one of the most important areas of
sports medicine, which plays an increasingly role in selection
of athletes, optimisation of training, early diagnostics and pro-
phylaxis of sports pathology. Functional condition of the body
undergoes constant changes under the influence of a number of
factors. The differences may be considerable and pose prob-
lems related to the recruitment of athletes to teams in game
sports and in individual sports. Physical ability is determined
by the quality of external breathing and cardiovascular func-
tions and by peculiarities of metabolism related to the tissue
breathing and transport of substrates. In qualitative assess-
ment of these phenomena one must relate the parameters of
the individual’s functional conditions to the required or de-
sired values, i.e. norms. On the other hand, there exist no
norms for a comprehensive evaluation of the Lithuanian per-
sons’ physical capacity and breathing system and metabolic
function capacity including residents going in for sports. It is
not clear whether one may rely upon the nomograms drawn
up by foreign authors because they may not be applicable to
Lithuanian athletes for a number of possible reasons: differ-
ences in training methods, regional cultural environment (dif-
ferences in energy requirements in daily life), nutritional as-
pects, even demographic peculiarities taking into account limited
assimilation level and small number of inhabitants. It has been
established that the maximum oxygen uptake indicators
reflecting the body’s dynamic potential are different in elite
athletes when evaluated during a standard ergo metric test.
The aerobic capacity is determined by all links in the oxygen
transport chain, since both heart rate (HR) and breathing indi-
cators (VE-ventilation volume, PEF-peak expiratory flow and
RR-respiratory rate) are characterised by equally good
correlation with the oxygen uptake indicators and high deter-
mination coefficients (all r>0.95, R2>95%, p<0.01).
