physical effort the needs of oxygen and nutrients supplies of the
tissues increase based to the intensity of the work performed. The
changes that appear in the system represent adaptative reactions to the
hemodynamic overloads in volume and pressure.
adjustment to effort implies modifications that appear in all the
system’s components – heart, blood vessels and blood. The
changes aimed at both quantitative and qualitative aspects, as well as
morphological and functional aspects. The adaptation capacity of the
human body belongs to the natural evolution and it is conditioned by
the differences of the individual responses of the body to the stimuli
induced by the physical effort.
One of the main
problems of the functional cardiovascular diagnostics, for trained or
untrained persons, is to define the functional disorders, induced by
the autonomic nervous system adjustments, from the organic disorders.
hypotheses from which we departed in this research were that the
organized and systematic practice of physical effort determines
improvement of the neuro-functional cardiovascular response, and thus,
the improvement of the individual’s health. The dimensions of the
functional adaptations depend on the level of demand to which the body
is subjected, meaning the duration and the intensity of the effort.
Research took place at the National University of Physical Education
and Sports between 2012-2014 on two batches of students belonging to
the Physical Education and Physical Therapy Faculties. The two batches
were made up of 50 students, 25 girls and 25 boys from the structure of
one full cycle and were studied annually in the first and second year
of study. The tests used to assess the response of the cardiovascular
system were the clino-orthostatic reflex and Schellong test.
a conclusion the hypotheses was confirmed, the evolution of the average
values of the pulse and blood pressure during the changes in body
position was improved, more obvious for the first batch (physical
education), especially in the second year.
