Conventional wisdom suggests that running on softer surfaces is better for the body than harder surfaces. However, in a recent New York Times article, the subject of running injuries on hard versus soft surfaces was examined. Exercise physiologist Hirofumi Tanaka of the University of Texas at Austin took a deeper look at soft-surface running and said he could not find any scientific evidence that a softer surface benefits runners. Tanaka developed an interest in the topic after experiencing a running injury. When he was recovering from a knee injury, an orthopedist told him to get off the roads and hit the trails. He took that advice and twisted his ankle and aggravated the injury while running on the softer, irregular surface.
In the aftermath of his accident, Dr. Tanaka said he could not find scientific evidence supporting that a softer surface is better for runners than a hard one, nor could other experts he queried. In fact, he suggested that it makes just as much sense to reason that runners are more likely to get injured on soft surfaces, which often are irregular, than on smooth, hard ones.

Stars and Stripes reported that the Navy has made changes to its Physical Readiness Program. According to the article, if sailors are unable to meet body fat standards, it will result in an overall failure of the physical fitness assessment, and they will not be allowed to take the rest of the physical fitness test.
The Navy’s move is similar to the Army’s revision of its own training program to deal with overweight and unfit recruits. Navy sailors will be required to meet the body composition guidelines and will be rated on a new five-tier scale of outstanding, excellent, good, satisfactory, or failure.

A recent Wall Street Journal article reported on multivitamin use, the issue of what one actually needs to take, and understanding what is on the labels. The article asks the basic question: Do you really need a multivitamin? And what exactly should a person be looking for in a multivitmin?
According to the article, there is no generic, one-size-fits-all multivitamin that is capable of meeting every nutritional need, and factors such as age, gender, diet and health determine what vitamins a person should take, if any. Adding to the confusion is inconsistent vitamin labeling for consumers as well as the manufacturers who tailor product brands for different population segments.
Probiotic products were seized by U.S. Marshals after the Food and Drug Administration (FDA) complained that the products were marketed as drugs.

More information is provided in the FDA News Release.
Research at USARIEM (U.S. Army Research Institute of Environmental Medicine) was featured in a article by writer Christopher Solomon titled "G.I. Joe and the House of Pain" in a special issue of Outside Magazine about human performance. The author spent time in the research lab's heat chamber, altitude chamber, and cold-water pool—conditions that simulate the extreme environmental conditions found in theater. He interviewed research physiologists there about USARIEM's work over the past 50 years as well as its current studies, all of which address the crucial issues of Warfighter health and performance in extreme environments.
Food Safety News is reporting that Senator Dick Durbin (D-IL) has asked the FDA to clarify its regulatory position on dietary supplements and food additives on the back of widespread concerns about the marketing of melatonin-containing baked goods. A recent HPRC Performance News post notes that there have been questions raised on commercially available products such as Lazy Cakes and Lulla Pies that are marketed as "relaxation" brownies - which contain high doses of the sleep aid melatonin.
These products are being sold as dietary supplements to help people relax and fall asleep, rather than foods containing additives. Senator Durbin contends that these foods are being sold as dietary supplements but are really foods containing a dietary ingredient additive, which would require FDA approval. He has asked U.S. Food and Drug Administration (FDA) Commissioner Margaret Hamburg to see if she has the authority "to oversee the safety of foods containing dietary supplement additives."
