5. Why is the Athlete Mode necessary in a Body Composition Scale?
It has been found that body fat estimation using BIA could overestimate the
percentage body fat of adult elite athletes. The physiological variation of
athletes in bone density and level of hydration are two of the reasons said to
account for the difference. The Athlete mode is selectable only for people 15
years of age or older.
6. De
fi
nition of an Athlete
The general consensus among researchers is that a quantitative dimension
could be used in de
fi
ning an athlete. For example, an athlete could be de
fi
ned
as a person who consistently trains a minimum of three times per week for two
hours each time, in order to improve speci
fi
c skills required in the performance
of their speci
fi
c sport and/or activity.
7. What is Muscle Mass?
Our Body Composition Scale estimates the weight of Skeletal Muscle Mass in your body.
You have around 650 muscles in your body, and they make up roughly half of
your body weight. These muscles can be divided into three different groups:
skeletal, smooth and cardiac. All of these muscles can stretch and contract, but
they perform very different functions.
Skeletal muscle:
Produces movement, maintains posture, stabilizes joints and
generates heat
Smooth muscle:
Found in the walls of hollow organs
Cardiac muscle:
Exists only in your heart
Skeletal muscle
The tissue most commonly thought of as muscle is skeletal muscle. Skeletal
muscles cover your skeleton, giving your body its shape. They are attached to
your skeleton by strong, springy tendons or are directly connected to rough
patches of bone. Skeletal muscles are under voluntary control, which means
you consciously control what they do.
Just about all body movement, from walking to nodding your head, is
caused by skeletal muscle contraction. Your skeletal muscles function
almost continuously to maintain your posture, making one tiny adjustment
after another to keep your body upright. Skeletal muscle is also important
for holding your bones in the correct position and prevents your joints from
dislocating. Some skeletal muscles in your face are directly attached to your
skin. The slightest contraction of one of these muscles changes your facial
expression.
Skeletal muscle generates heat as a by-product of muscle activity. This heat is
vital for maintaining your normal body temperature.
Skeletal muscle represents approximately 30% of body weight of a healthy
127.8 lb woman or 40% of a 154.3 lb man. (International Commission on
Radiological Protection, 1975)
