Effects of physical exercise and a healthy diet

Nutr. clín. diet. hosp 04/2009; 29:46-53.


Exercising regularly provokes physiological adaptations
resulting in benefits for health, that last until
some time after having finished the practice of the
exercise. Physical exercise has to be individually programmed
with the help of a specialist. In particular sedentary
people have to increase progressively the intensity
and duration of their training activity, until their
objectives are reached. Adaptations that occur by
exercising are only visible in the long term and are dependent
on the type of training made (ie.: achieving
greater resistance to fatigue, greater aerobic power,
speed, to control weight, to feel better, etc.).
During the practice of physical exercise, hundreds of
genes are activated to trigger the catabolic and anabolic
processes, allowing the muscles to generate energy
for contractions and afterwards, at the end of the exercise,
to replenish the glycogen stores and repair the
damaged tissues by means of resting and eating.
Those processes are perfectly tuned, because they
have been adapted by millions of years of evolution,
and could be used to correct the metabolic disorders of
people (obesity, Diabetes type 2, etc.).
The correct diet rich in carbohydrates and the rehydration
after the exercise, play as well an important role
in the healthy style of life as it is showed in this modest
review work. (article in Spanish).
