Overfatness or obesity can contribute to degenerative diseases, health problems, and even shortened life.
Some diseases and health problems associated with overfatness and obesity are presented in Concept 3. In addition to the higher incidence of certain diseases and health problems, there is evidence that people who are moderately overfat have a 40 percent higher than normal risk of shortening their lifespan. More severe obesity results in a 70 percent higher than normal death rate. This is evidenced by the exorbitant life insurance premiums paid by obese individuals.
Recent statistics indicating that underweight people had a higher than normal risk of premature death are very deceptive. Many people included in the data were underweight because of terminal illnesses. Most experts agree that those people who are free from disease and who have lower than average amounts of body fat have a lower than average risk of premature death. (more…)

Poor alignment of the body parts during exercise and sports can affect efficiency and effectiveness of performance.
Examples of poor alignment that is detrimental in sports include weight lifters arching the back when doing a lift from the squatting position or during a bench press. This violates the normal mechanics of the spine and is a common cause of backaches in athletes. Gymnasts are also prone to back problems because they sometimes perform with a swayback, especially during landings.
Lordosis in runners causes a short, choppy gait and may cause back pain. Poor posture also influences the way the runner’s foot strikes the ground, contributing to either foot shock or shin splints. In addition, runners may have a back problem as the result of an excessive forward lean.
Dancers and ice skaters sometimes assume poor postures in the execution of jumps. If they land on one leg while the lower back is hyperextended, there is an enormous shearing force on the lumbosacral joint and excessive compression on the disks.

Poor posture, especially lordosis, can cause back strain and pain and can make the back more susceptible to injury.
The forward tilt of the pelvis may cause the sacral bone or one of the lumbar vertebrae to press on nerve roots with consequent low back pain and sciatica. To be on the safe side, some authorities advise those who have lordosis and weak abdominals to eliminate all exercises that hyperextend the spine. Incidence of lordosis is about the same for men as it is for women, except that women experience an added back strain during pregnancy, and high heels may also contribute to spinal strain.
Some people have a “flat back” (lumbar kyphosis) in the lower back region that can lead to backaches.
There is an increased interest by therapists in patients who lack a normal lordotic curve in the lumbar spine. Robin McKenzie’s theories and exercises (1980) (1981) (1983) have become increasingly popular in the treatment of people who sit for long periods with the back flat and pelvis tilted backward or those who engage in prolonged bending, heavy lifting, and long standing with flat back postures.
These people may need to regain a normal lordotic curve and probably need to perform relaxed static stretches with the back in hyperextension, such as the Press-Up Exercise. They may also benefit from the use of lumbar support (rolls or pillows) during sitting. (more…)

Good posture has aesthetic benefits.
The first impression one person makes on another is usually a visual one. Good posture can help convey an impression of alertness, confidence, and attractiveness.
There is probably no one best posture for all individuals, because body build affects the balance of body parts. In general, certain relationships are desirable, however.
In the standing position, the head should be centered over the trunk, the shoulders should be down and back, but relaxed, with the chest high and the abdomen flat. The spine should have gentle curves when viewed from the side, but should be straight as seen from the back. When the pelvis is tilted properly, the pubis falls directly underneath the lower tip of the sternum. The knees should be relaxed, with the kneecaps pointed straight ahead. The feet should point straight ahead and the weight should be borne over the heel, on the outside border of the sole, and across the ball of the foot and toes. (more…)
