The long-term effects of exercise on the muscular system
Tendon strength
• Tendons, like muscles, adapt to
the mechanical loading of regular
exercise and become stronger.

Hypertrophy
• The muscle size and strength
increases due to an increase in
the volume of the contractile
proteins within the muscle cells.
This allows for a more forceful
contraction.

Myoglobin
stores
• The amount of myoglobin within
skeletal muscle increases, which
allows more oxygen to be stored
within the muscle, and
transported to the mitochondria
(the cells power house). The
numbers of mitochondria also
increase through exercise
resulting in an increased rate of
energy production.

Glycogen and fat stores
• Exercise can increase the
muscles ability to store glycogen
and fat and therefore the amount
of potential energy available.

Effects
Muscle
strength
• Anaerobic training increases the
muscles tolerance to lactic acid.
Aerobic training extends the
capillary network, improving the
oxygen supply to the muscles.
This results in the muscles being
able to work for a longer duration
and at a higher intensity without
fatiguing.
