Mental Attitude: “Heading” a Soccer Ball May Be More Dangerous for Women.
Several studies have linked heading soccer balls with an increased risk for brain injury and new research suggests that the danger is even greater for female athletes. In the study, researchers compared brain scans of 49 female and 49 male amateur soccer players who reported a similar number of headings over the previous year (about 470 to 490) and observed far more extensive damage in the brains of the female participants. Study leader Dr. Michael Lipton explains, “Researchers and clinicians have long noticed that women fare worse following head injury than men, but some have said that’s only because women are more willing to report symptoms… Based on our study, which measured objective changes in brain tissue rather than self-reported symptoms, women do seem more likely than men to suffer brain trauma from heading soccer balls.”

Diet: Healthy Diet Linked to Lower Cancer Risk.
An analysis of dietary and health data concerning over 40,000 adults suggests that greater adherence to the Mediterranean diet—which focuses on fruits, vegetables, grains, olive oil, fish, lean meats, and nuts/seeds—is associated with up to a 12% lower overall cancer risk.

Exercise: Muscle “Switch” May Determine Benefits of Exercise.
Scientists have discovered a molecular “switch” that may explain why some people benefit from aerobic exercise and strength training, while others do not. Using both animal and human subjects, researchers discovered that a protein called C-Jun N-terminal kinase (JNK) helps to determine our response to exercise. If JNK is activated during exercise, it stimulates skeletal muscle growth. If it’s not activated, muscles will improve their adaptation for endurance and aerobic capacity. Further research is needed to determine JNK’s implications in the prevention of cardiovascular disease and its possible role in building muscle to fight muscle-wasting diseases.

Chiropractic: Most Women Have Back Pain During Pregnancy.
Questionnaires completed by 287 expectant mothers revealed that 76% experienced back pain during their pregnancy. Additionally, the researchers found that nearly a third of the participants in the study reported both back pain and pelvic girdle pain, with the risk for each increasing over the course of the pregnancy. The research team adds that women with a previous history of back pain or pelvic girdle pain have an elevated risk for experiencing such pain while pregnant.

Wellness/Prevention: How to Prevent Foot Blisters.
Friction against the skin can lead to blisters on the feet, especially when wearing ill-fitting shoes. To prevent foot blisters, the American Academy of Dermatology recommends the following: wear socks that wick away moisture, make sure to wear shoes that fit properly, apply soft bandages to protect problem areas, apply powder or petroleum jelly to reduce friction, and stop the current activity immediately if you have foot pain or discomfort.
