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 58 kg
woman or 40% of a 70 kg man. (International Commission on Radiological
Protection, 1975)
8. What is Bone Mass?
Our Body Fat Scale estimates the weight of non-living bone mineral content. This
is important for monitoring and maintaining healthy bones through exercise and
calcium-rich diet.
An adult skeleton is made up of 206 bones, which come in several different shapes and
sizes and have specific structure.
Your bones contain blood vessels, nerve cells and living bone cells known as osteocytes.
These are held together by a framework of hard, non-living material containing calcium and
phosphorous. A thin membrane called the periosteum covers the surface of your bones.
Bone Mineral Content differs according to age and sex.
For Adults: The average bone mineral content of 15-29 year old female is approximately 2.7
kg, that for 15-29 year old male is approximately between 2.7 and 3.5 kg. (Rico et al. 1993)
For Children: The average bone mineral content of 8-16 year old child is approximately
between 0.8 and 2.2 kg. (Faulkner et al. 1993)
9. What is Fat Mass?
Fat Mass is the total weight of fat mass in the body.
10. What is Fat-free Mass?
Our Body Fat Scale estimates the weight of fat-free mass in your body.
Fat-free mass
is comprised of the nonfat components of the human body. Skeletal
muscle, bone and water are all examples of fat-free mass. Fat-free mass can refer to
any body tissue that does not contain fat.
11.What is Body Mass Index (BMI)?
BMI is a ratio of a person’s weight to height. BMI is commonly used to classify weight as
“healthy” or “unhealthy”.
