Minimalist running shoes: Do they really prevent injuries?

Barefoot-style running and minimalist running shoes are growing in popularity, but some new research now shows there are risks.

Barefoot-style, or minimalist, running shoes are still growing in popularity in the military, and the debate continues over whether this style of running prevents injuries or just causes different injuries. There is new research on minimalist running shoes (MRS) and their impact on lower leg and foot injury. After a 10-week study, runners who transitioned to Vibram FiveFinger minimalist running shoes showed signs of injury to their foot bones, while the runners who used traditional running shoes showed none. The types of injuries the MRS runners demonstrated were early signs of inflammation, which may or may not be associated with pain or joint dysfunction. If they are, it might be difficult for the runner to know he/she is actually injured until it is too late and the injury has progressed. More research is needed to determine if other factors (weight, running form/style, mileage, running surface) contribute to injuries associated with barefoot-style running. At least one recent study suggests running style may be a factor. For more in-depth information, read HPRC’s InfoReveal.

FDA warns: DMAA in dietary supplements now illegal

FDA urges consumers to check all dietary supplement product labels to ensure they do not contain the illegal stimulant DMAA.

The Food and Drug Administration (FDA) has issued a Consumer Update warning of the potential dangers of DMAA, which was announced illegal in dietary supplements on 11 April 2013. DMAA is also referred to as dimethylamylamine and other names. This dietary supplement product ingredient has been used in many weight-loss, bodybuilding, and performance-enhancement products. FDA received numerous reports of illnesses and death from the use of products containing DMAA; commonly reported reactions include heart and nervous system problems as well as psychiatric disorders. DMAA has been the focus of conflicting information regarding whether or not it is a natural extract from geranium. FDA has now found “the information insufficient to defend the use of DMAA as an ingredient in dietary supplements.” Online, FDA also stated, "Dietary supplements containing DMAA are illegal and FDA is doing everything within its authority to remove these products from the market."

Raspberry ketone—the latest weight-loss craze

Raspberry ketone is a food additive and aromatic compound now being sold as a dietary supplement/ingredient touted to reduce fat and weight. Find out the facts and the science behind it all.

Raspberry ketone, touted to be an effective fat-loss and weight-loss supplement, occurs naturally in various red raspberries. The raspberry ketone in supplements is probably produced in the laboratory, as it would be too expensive to extract it from real raspberries. FDA recognizes that raspberry ketone as a food additive is “Generally Recognized as Safe” (GRAS) to consume in small amounts. However, the long-term effects in humans who consume it as a supplement are unknown. For more information, read HPRC’s InfoReveal on “Raspberry ketone.”

Dietary supplements and surgical procedures

Be careful about using dietary supplements if you are planning to have surgery or if you have recently had surgery. Some ingredients could cause problems.

Be extra cautious when taking dietary supplements before and after surgical procedures; some products can have serious negative effects on surgical procedures. For instance, certain supplements prevent certain blood cells (platelets) from clumping, resulting in excessive bleeding during surgery. Some of the ingredients commonly found in supplements that hinder platelet aggregation are ginko biloba, saw palmetto, glucosamine, black tea, fish oil, and garlic. If you are having a surgical operation, consider abstaining from these items or consume these items in moderation a few weeks before and after the procedure. For more a complete list of products and additional information, including other surgical risks associated with dietary supplements, read this web page from the Natural Medicines Comprehensive Database. And always read product labels carefully; many include warnings of potential medical risks, including the length of time prior to surgery that you should discontinue use.

Accident prone? Get some sleep!

HPRC Fitness Arena: Total Force Fitness
When it comes to reducing your risk for accidents and enhancing your performance, sleep is one tool that has comprehensive benefits!

Did you know that missing a night of sleep can produce performance results similar to those of being legally drunk? Even losing just a few hours of sleep can result in accidents and poor physical and mental performance. Sleepiness can inhibit balance, coordination, concentration, and response time—creating “the perfect storm” for accidents.

Make sure your sleep is optimal by turning off your electronics and other distractions well before bedtime, exercising during the day, avoiding caffeine late in the day, and sticking to a consistent sleep schedule. If you are in a situation where sleep is hard to come by, try to squeeze in naps when possible. For more information and ideas, check out HPRC’s article on sleep and visit HPRC’s Sleep Optimization resources.

Caffeine in supplements – how much?

Some of the most popular dietary supplements sold on military bases may give inaccurate—or no—information about caffeine content on their labels.

A Military Times article reports on a recent study of more than 30 of the most popular dietary supplements (in capsule form) sold on military bases analyzed to determine their caffeine content. Of the 20 supplements that listed caffeine as an ingredient on their labels, six did not specify the amount. These same six contained high amounts of caffeine (210-310 mg per serving)—three or more times the amount permitted by law in soft drinks. Five others revealed significantly different amounts—some more, some less—than the quantity stated on the product label.

Consuming too much caffeine can result in health issues. And if you don’t know how much is in the supplement you’re taking, it could be easy to overdo it if you also drink coffee or energy drinks. Visit the Operation Supplement Safety (OPSS) FAQ on caffeine for additional information.
