Sports giants Reebok recently brought out a range of trainers designed to improve toning in the legs and bum. They called the range ‘easytone’, which spanned from the concept of the shoe. The trainers are designed with a convex sole which creates instability; it forces the foot to balance on a smaller surface area than usual. This means the leg is constantly trying to find a balance point and keeps the muscles working on a small scale, even while walking.
With this concept, Reebok claim that it increases the activation of calf muscles by 11% and gluteus maximus muscles by 28%. The idea is to give your legs and bum a workout without actually doing much exercise, apparently from the advert it even works while cleaning the house!
John Porcari PhD, who led the tests, agrees that the trainers should work in theory as they make the muscles work harder by creating instability that the body attempts to counteract. The shoes are based on a curved sole which creates an unstable surface which forces the wearer’s body to constantly struggle to find equilibrium.
The Reetone range was tested on a group of females aged 19 to 24. The subjects were put through exercise trials and had muscle activation, heart rate and caloric expenditure measured.
The University of Delaware conducted a test with a group of women, they made half wear the Easytone shoes and the other half wore standard fitness trainers. The women endured a series of exercises while attached to sensors which monitored muscle activity.
The results declared an increase in muscle activity for the subjects wearing the Easytone trainers in the muscles specified, but not to the degree Reebok claimed. The verdict is that although the trainers do provide a small degree of extra muscle usage, they are fairly expensive and it would depend on the individual consumer as to whether they believed it was worth it. Judging by the perky models featured in the advert, the campaign is likely to be very successful in convincing consumers of this.
Consumers can get their hand on the easytone trainers in stores and online and there is rumour of a extended Reebok easytone due next year.
