Increasing exercise capacity by cooling hands

In the study, obese women who exercised while using the AvaCore Rapid Thermal Exchange (RTX palm cooling device) improved their exercise tolerance and cardiovascular fitness.
The cooling devices cooled the palms of the hand and circulating blood, thus pulling heat off the body.Exercise linked to change in DNA

The researchers explain that although the genetic makeup is not altered, DNA molecules change structurally and chemically when a person exercises. An example of this is the DNA gaining more or losing parts of methyl groups that are found on sequences of DNA families.
During the study, DNA within skeletal muscle was taken from people who had just experienced a round of exercise. The DNA showed less methyl groups than it had before the person’s work out. The changes were found in the areas of DNA which work as stopping places for a certain kind of enzymes, called transcription factors. These enzymes are very important in terms of muscles and exercise.
Trampoline Advice Issued By Orthopedic Surgeons

“Although trampolines can be fun for both kids and adults, they pose a high risk for injuries, especially when two or more people jump at one time. Orthopedic surgeons recommended that trampolines not be used in home environments or in outdoor playgrounds because of the high risk of injuries from this activity.”
The AAOS has created an audio public service message as well as a position statement regarding trampoline safety in order to prevent injuries sustained from trampolines, rather than treat them.
In children with ACL injuries, surgery delay can cause irreparable meniscus tears

For children aged 14 and under, delaying reconstructive surgery for anterior cruciate ligament (ACL) injuries may raise their risk of further injury, according to a new study by pediatric orthopaedic surgeons. If surgery occurs later than 12 weeks after the injury, the injury may even be irreparable.
ACL injuries have increased among children and young adults in recent years, possibly because of increased participation in high-level sports such as football, skiing, lacrosse, hockey and soccer, all of which place a high demand on the knees, where the ACL is located.
Pediatricians sound alarm on overuse sports injuries
Children are prone to sport-specific trauma to the growth plates. For example, dancers, skaters and cheerleaders are vulnerable to ankle damage, while baseball and football players tend to injure their shoulders and elbows. Runners suffer shin pain and knee problems, while gymnasts are prone to wrist damage from repetitive weight bearing.
“The combination of repetitive use and skeletal immaturity puts these youngsters at high risk for injuries, some of them long-lasting, so it is really important that young children have whole-body conditioning and engage in a variety of athletic activities rather than one sport,” Valasek says.
Stand Up: Your life could depend on it

Standing up more often may reduce your chances of dying within three years, even if you are already physically active, a study of more than 200,000 people published in Archives of Internal Medicine shows.
The study found that adults who sat 11 or more hours per day had a 40% increased risk of dying in the next three years compared with those who sat for fewer than four hours a day. This was after taking into account their physical activity, weight and health status.
Can surgery help you stay in the game?

Demand for joint replacement surgery, once confined largely to patients well past retirement age, has been growing rapidly among a class of people doctors have dubbed the “young actives” – those in the 45 to 64 age group who are determined to stay fit.
Still, even with the rise of obesity and longer lives, public health researchers say the rate of joint replacement failures requiring revisions is about 1 percent a year, mostly in the relatively younger patients who “outlive” the 10-to-20-year working life spans of their replacement joints. And as technique and technology have improved, the rates of infection, dislocations, and other complications have declined.
New method will increase likelihood of success in cartilage grafting procedures
Source: Medical News Today
For years, doctors have been able to treat defects in joint cartilage by grafting cartilage donated from cadavers into patients’ bad joints. Using current methods, donated cartilage can be stored for 28 days for a transplant before the tissue becomes too degraded to transplant into a patient. Now, researchers from the University of Missouri have found a way to store donated cartilage more than twice as long.
In a study due to be published in the Journal of Knee Surgery, Cook and Aaron Stoker from MU’s Comparative Orthopaedic Laboratory, Clark Hung and Eric Lima from Columbia University, and James Stannard, the J. Vernon Luck Sr. Distinguished Professor in Orthopaedic Surgery in the MU School of Medicine, tested tissue using their patented system, which includes storing the tissue at room temperature in a specially designed container and storage solution. The researchers found that their system preserved transplant-quality tissue for as long as 63 days. The collaborative team of researchers also developed a way to monitor the quality of the stored tissue simply by testing a few drops of their patented storage solution.
New treatment for tennis elbow

Steroid injections are no longer routinely recommended for lateral epicondylitis (tennis elbow). Instead, physical therapists offer an alternative treatment in the form of something called iontophoresis.
In this article, the use of steroid injection is compared with iontophoresis delivered in two different ways. Iontophoresis uses a small electric current to drive steroid medication through the skin. It is a noninvasive method of reducing the pain of tennis elbow.
Prevent back, neck and shoulder pain from prolonged sitting and bad posture

Back, neck and shoulder pain is the natural result of prolonged sitting at work behind a computer, as is bad posture. This can cause headaches and excessive tension in neck, shoulders, arms, forearms, wrists, back, hips, thighs and legs.
Preventing back and neck pain while sitting is not an exact science as there are many differing opinions on the subject. However, there are some common denominators on which most chiropractors and other medical professionals agree
