What muscles work.
The main benefit and valuable property of running
are that during it, almost all muscles of the human
body are comprehensively worked out. The main
load during classes is received by:
- gluteal and femoral muscles;
- shins;
- feet.
However, while running, the upper body also
actively works. Therefore, regular training helps
to improve the condition of the biceps and triceps,
dorsal and shoulder muscles and also improves
the tone of the abdominal and lumbar muscles.
The intensity of the load when exercising on
a treadmill must be regulated. You cannot
immediately go to training at the limit of strength
with zero physical preparation - this will be
harmful and cause aversion to classes. In total, a
useful workout should take beginners about half
an hour.
In general, running on the track differs little
from healthy jogging in the fresh air. However,
exercising indoors can negatively affect the
respiratory system if the room is too musty and
the temperature is too high. The room should be
ventilated during training.
On a treadmill, the human body rapidly loses its
fluid reserves. Therefore, before starting a useful
activity, you must definitely drink a glass of water.
