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.

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.

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."
