The power of muscle memory

HPRC Fitness Arena:
The number of hours a person spends pumping iron may make it easier to get back into shape and could also stave off weakness and decline in muscle function in old age. That's according to findings recently published in Proceedings of the National Academy of Sciences.

The number of hours a person spends pumping iron may make it easier to get back into shape and could also stave off weakness and decline of muscle function in old age.  That's according to findings recently published in Proceedings of the National Academy of Sciences.

In an interview with National Public Radio (NPR), Kristian Gundersen , one of the researchers of this study explains that muscles actually have a memory of their former strength — and that memory may last indefinitely. The article can be accessed here.

Questions raised on the effectiveness of toning shoes

HPRC Fitness Arena:
Toning shoes are exercise shoes that have a uniquely shaped rocker type sole and extra cushioning to alter the wearer’s normal walking gait. They are the latest trend in fitness footwear, but is all the buzz and manufacturer’s claims too good to be true?

Toning shoes are exercise shoes that have a uniquely shaped rocker type sole and extra cushioning to alter the wearer’s normal walking gait.  Manufacturers of toning shoes claim that wearers can tighten and shape their lower-body muscles just by walking in the shoes. They are the latest trend in fitness footwear, but is all the buzz and manufacturer’s claims too good to be true? Proponents of toning shoes cite that “instability of the shoes” forces the user to activate muscles that otherwise would not be used with regular exercise shoes. Additionally,  advocates for the shoes claim that by wearing toning shoes, you can change your posture and take pressure off aching, overused joints. However, a growing share of medical skeptics say no independent studies have shown benefits from these types of shoes over traditional pairs.

The American Council on Exercise (ACE), in conjunction with researchers from the University of Wisconsin, LaCrosse, released results of a study comparing the effects of wearing toning to traditional running shoes. Seems the claims may not be true.

Caffeine can boost sports performance

HPRC Fitness Arena:
High doses of caffeine can increase muscle power and endurance, researchers from Coventry University said in a news release.

The June 29 edition of the Telegraph.co.uk published an article titled Caffeine can boost endurance racing. The article cites research done by Coventry University and reports that high doses of caffeine can increase muscle power and endurance.

Study author Dr Rob James, from the University of Coventry's Department of Biomolecular and Sports Science, said: "A very high dosage of caffeine, most likely achieved via tablets, powder or a concentrated liquid, is feasible and might prove attractive to a number of athletes wishing to improve their athletic performance.

"A small increase in performance via caffeine could mean the difference between a gold medal in the Olympics and an also-ran."

New report on protein drinks

HPRC Fitness Arena:
Recent surveys of dietary supplement use indicate that about 20 percent of active duty personnel are using some type of protein powder. The percentage of users is likely higher among special operations personnel, and this is of concern, given the July 2010 Consumer Reports® alert on protein drinks.

Recent surveys of dietary supplement use indicate that about 20 percent of active duty personnel are using some type of protein powder. The percentage of users is likely higher among special operations personnel, and this is of concern, given the July 2010 Consumer Reports® alert on protein drinks. These powder products are typically mixed with milk, water, or another liquid to make a shake and promoted as a sure way to increase muscle mass. The products often come in different flavors, with strawberry and chocolate the mainstays.

The Consumer Reports® Alert indicated that most of the 15 protein drink products analyzed contained miniscule to concerning amounts of selected contaminants – arsenic, cadmium, lead, and/or mercury – each of which is toxic to various organs in the body. Military personnel commonly use several of the products noted in the report. These include EAS Myoplex Original Rich Dark Chocolate Shakes; Muscle Milk chocolate, vanilla crème, and nutritional shake beverages; MuscleTech Nitro-Tech Hardcore Pro-Series Vanilla Milkshake; selected GNC products, and BSN and Optimum Nutrition whey protein products.

It is important to note that if three servings of these products were taken per day, consumers could be ingesting amounts of these contaminants in excess of the maximum limits proposed by the United States Pharmacopeia, the authoritative standard for health products. Importantly, toxic effects have been reported from using these products and are of concern because the Food and Drug Administration does not require such products to be tested to confirm the absence of contaminants and other potentially dangerous products before they are sold.

Take Home Message: A chicken breast, three 8-oz glasses of milk, and three eggs are inexpensive sources of high quality protein, whereas protein powders are expensive sources of uncertain quality, and potentially contaminated, protein. It is both better and cheaper to eat real foods.
