Benefits of physical activity are undeniable. The
aim of the present research was to determine the effects
of physical activity and age on cholesterol and glucose
levels in the blood, as well as changes in the functional
parameters of the cardiovascular system, during stepwise
increases in physical load for men employed in the same
place, but with different levels of physical activity. The
subjects were 95 military officers who were divided into
groups according to the level of physical activity of their
occupation, with veloergometry used as physical load.
Cholesterol and glucose levels in the blood were taken
as biochemical indices. The results showed that occupational
physical activity had a positive effect on biochemical
and cardiovascular functional parameters before,
during, and after the physical load. Only the cardiovascular
rate (systolic blood pressure) in older subjects was significantly
higher than that of the younger persons; for all
other parameters, age had no effect at all.
