A chiropractor who also was coach of the U.S. Olympic men's water polo team helped the group to win the silver medal in Beijing, in a match against Hungary, by providing members with daily chiropractic adjustments.

"I can honestly say that without chiropractic, many Olympic athletes would not be able to perform to their potential," said Merrill Moses, the team's goalkeeper. "We take such a pounding on our bodies, especially in water polo, because it's a contact sport. I like to get a chiropractic adjustment every day just to keep my body healthy."

Treating and preventing chronic neck pain can often be successfully accomplished by something as simple as adopting correct posture while waking and sleeping.

While the pain sufferer can treat the symptoms of frequent neck "cricks" with neck stretch exercises, painkillers or ice applications, the symptoms' root causes must be dealt with differently. These root causes often involve some kind of poor posture, says Dr. Brian Bruel, an assistant professor of physical medicine and rehabilitation on the one hand, and anesthesiology and pain management on the other, at the University of Texas Southwestern Medical Center. Posture violators might crouch over a desk all day long, slouch on a sofa while watching TV, or contort themselves while reading. (Read more about One Simple Solution to Neck Pain: Good Posture)

People who are physically active in their free time may be biologically younger than those who live sedentary lifestyles, a recent British study suggests. Researchers looked at the physical activity levels, smoking habits and socioeconomic status of 2,400 white twins. DNA samples were collected from participants in order to examine length of telomeres-repeated sequences at the end of chromosomes in white blood cells - which serves as a possible marker of a person's biological age. Study participants had an average telomere loss of 21 nucleotides per year. But those who were more active in their leisure time had longer leukocyte telomeres than those who were less active.

A study by researchers at the University of South Carolina has found that fitness may be more important to longevity, than body weight. People who are not at optimal weight but who are active have a lower mortality risk than those of normal weight but low fitness levels. The study was conducted by researchers who tracked 2,600 people ages 60 and older to determine how physical fitness and body fat affected their death rates over a 12 year period. During the study there were 450 deaths. The participants were assessed by a treadmill test, weight, and body mass index. The researchers found that those in the lowest fifth rank of fitness had a death rate of four times higher than participants ranked in the top fifth. The results indicate that being fit provides protection against mortality in men and women 60 and older, whether they're normal weight or overweight..
