So body must have power house to generate power and supply energy to fuel different functions.And it has.Oh Zemanta has already found it out.I could see it on my right side, the reference.Please go through it.We get most of power by burning glucose and secondly fat.Glucose burners are somewhat like thermal power generators .They use coal and body uses glucose. These power house of body are mostly located in the muscle celled called Mitochondria.They generate what is called ATP( Adenosine Triphosphate ) .ATP convert to ADP in the process of releasing energy.
In a resting state of muscle i.e.Limited exercising muscle mitocondrias are in numbers just as much as required to generate the power need of body.Their number increases when a muscle group exercise regularly.Regularly I mean their should not be long intervals in term of many days between exercise spells. Five to four days a week means regular .Rest of one or two days in a week for muscles is also required for the repair from wear and tear they sustain from continuous work.Long intervals of rest for muscle get them back to the resting state and reduce the number of power houses in them.And that is why diabetics on life style modification will get back the raised blood sugar level again.Of course once exercise is resumed the number of mitochondria will increase again.
Exercise performed in whatever form should be continuous in nature to get best result out of it at least for the diabetics.
