So, is there really no such thing as spot training? Of course there is, but I had to ask anyway. Last year, published in The American Journal of Physiology, scientist found things like chronic sitting make your buttocks big. This is one of the body’s natural process in order to accommodate certain stresses put upon it. So, how exactly did this study come about that sitting will make your booty larger and fatter?
Case: Professor Amit Gefen from Tel Aviv University in Israel, along with his colleagues, found that sustained pressure, also known as mechanical stretching loads, cause preadipocyte cells (undifferentiated fibroblast that can be stimulated to form adipocytes– or fat cells) to become more fat cells at a faster pace. Up to 50% more.
Mechanical Weight Load is the amount/kind of weight we place on a particular area occupied by cells when we sit or lie down.
How: Prof. Gefen and his colleagues stimulated preadipocytes with glucose or insulin to differentiate them into adipocytes (fat cells) and created a simulation of long periods of lying down or sitting in a cell stretching machine. After the cells reached maturity, they were 50% fatter.
It’s also important to remember muscle atrophy is also common with inactivity. However, even with exercise, the most active woman can’t escape this inevitable doom of mechanical weight load over prolonged periods.
