Electronic stimulation has been used to restore atrophied or injured muscles to normal function during the rehabilitation process, according to the American Academy of Family Physicians. With the benefits tested and noted through physical therapy modalities and clinical trials, consumer exercise products such as the Contour Ab products have emerged. There are two products, the Contour Belt and the Contour Sport, available on the market. Consult a doctor before using any electrical stimulation device.
Contour Core
The Contour Core is a waist belt utilizing electrical stimulation to engage fast twitch muscle fibers in the abdominal region. The belt is Velcro-fitted to fit most waistlines. Once the belt is in place, the control box slips on the belt or hides in your purse or pocket. The unit is an FDA-cleared Class II medical device, similar to the devices used by athletes and physical therapists around the country. You can choose different stimulation levels to build up the muscle exertion. The belt can be used anywhere while sitting or exercising. The product's recommended use is 10 minutes, three times per week.
Contour Sport
The Contour Sport is an athlete's personal electric stimulation system designed to improve power of both fast- and slow-twitch muscle fibers, increase muscle stamina and aid in faster recovery. Athletes use the Contour Sport to shorten warm-up times and better prepare muscles for exertion. The unit includes eight gel pad electrodes that can be placed in customized locations to suit different sport needs. The Contour Sport has five levels with 22 programs for 100 different intensity levels.
Scientific Evidence
Before you starts any electrical stimulation training modality, consult a doctor to make sure you are healthy enough to use the unit. Those with a history of seizures, pace makers or other nerve conditions should refrain from using the units. Never place an electrical stimulation machine near your throat or on your head.
Research remains inconclusive as to whether electrical stimulation devices improve muscle tone and strength. A study published in the "Journal of Rehabilitation Medicine" in July 2008 showed no major benefits in strength. However, a study by J. Porcari and colleagues published in the "Workout Watchdog" in June 2010 on the Bottom Toner for the buttocks found that six weeks of training showed 15 percent increase in strength for those using stimulation compared to 9 percent for those exercising. More studies are required to create conclusive results.
