The Influences of Training on Rowers of Different Age

Sažetak
We measured 14 rowers and divided them into two groups according to age and
years of training. Our goal has been to establish the influence of several years of programmed
training on the structure of the body, oxygen carrying capacity and oxidation
capacity of muscle cells, the chemical composition of blood and characteristics of pulse
and lactate curves in rowers. As to the structure of the body, the two groups did not differ
if we equalised them according to body height. Differences existed in the determinants
of oxygen carrying capacity and oxydation capacity of muscle cells. Older rowers
had lower pulse at rest, higher step test index, lower pulse immediately after the step
test and in the last minute of the test on a bicycle ergometer and higher maximal oxygen
pulse. While at rest, no significant differences between the groups were observed in most
of the analysed substances in the blood serum. With the increase of age and training period
an increase of the concentration of creatinin and activity of creatin kinase and lessening
of the activity of alkaline fosfatase was noted. Length of training period lowers the
levels of cholesterol and free fatty acids and increases the level of triglycerides in blood
serum. An increase of the acttivity of creatin kinase and lactate dehydrogenase and the
formation of a specific pattern of isoenzymes was observed. The pulse and lactate curve
flattened and moved to the right.
