RESTING METABOLISM & SKELETAL MUSCLE
INCREASING SKELETAL MUSCLE THROUGH
EXERCISE
Skeletal muscle is muscle that is connected to bone and used to move parts of the body.
The maintenance and increase of this skeletal muscle is closely linked to resting metabolism.
This section describes resting metabolism and skeletal muscle.
What is Resting Metabolism?
Regardless of your activity level, a minimum level of energy is required to sustain the
body’s everyday functions. Resting metabolism, the amount of calories needed to supply
the body with the minimum level of energy, differs between individuals depending on
variables such as age, weight, body composition, and energy expenditure.
60-70% of daily energy use is for resting
metabolism
The total amount of energy burned by the body
in a typical day is as follows.
The ratio of these is 60%-70% for resting
metabolism, 20%-30% for daily activity, and
10% for diet induced thermogenesis. This
means that resting metabolism accounts for
most of our daily energy consumption.
If our daily food intake exceed the amount of
energy required for these activities, the
additional energy is stored as fat.
Resting metabolism
Energy required to
maintain vital functions.
Daily activity metabolism
Energy used for daily
activities such as
commuting to work,
household chores,
hobbies etc.
Diet-induced
thermogenesis
Energy emitted after
eating a meal.
