“Electrifying Abs”
August 16, 2010
Physical therapists and chiropractors sometimes use electrical-stimulation devices to rehabilitate damaged or weakened muscles. I have had this therapy on my ongoing injured shoulder. Nevertheless, there are professionals and companies outside the therapy world who claim that electrical stimulation can also help individuals develop “six-pack abs.” Devices come in various forms, from patches to belts, and promise users a non-exercise method for dropping weight. But is it really possible that these small machines can live up to the large claims? According to a study published in the Journal of Sports Science and Medicine, the answer is yes and no.
In the study, scientists electrically stimulated the abdominal regions of 24 adults 5 days per week for 8 weeks. The main focus was to determine the quantity of abdominal muscle activation and any resulting body composition changes affecting muscle definition.
When the study was completed, all subjects described that their abdominals felt “toned” and “firmed,” and 54% “felt an improvement in their posture.” Unfortunately, there were no differences in body weight, body mass index, or skinfold thickness over the course of the study. However, subjects experienced a 58% increase in abdominal strength and a 100% increase in abdominal endurance.
So it’s up to you. Are you up for good old fashioned exercises for the abdominals or do you think these devices follow through on their promises?
