Rethinking/phrasing hypothesis

Something that has recently come to my attention is the news of the obesity epidemic spreading to Mexico. I did a little bit of research on it and have found a significant amount of articles describing the increasing number of obese people in Mexico as well as the increasing number of Mexican children with type II diabetes. There are a couple of things that I think of with regard to this information. First- originally the hypothesis for this project has been that Mexican children will show an increased amount of core stability when compared to American children. This stems from the assumption that Mexican children are more active than American children because they lack the advanced technological sources of entertainment (tv, videogames, internet surfing/chatting etc) and because their culture requires more activity (walking to school or other places, engaging in manual labor at an earlier age, participation in sport- mostly soccer, which they are known for.) It seems however, that some of the same couch-potato habits may exist in Mexico at this moment. The kids and adults are getting fatter, at least in the bigger cities. The article, Bryan, L, & McLaughlin, H. J. (2005). Teaching and learning in rural mexico: a portrait of student responsibility in everyday school life. Teaching and Teacher Education, 21(1), 33-48. describes the transition from the more aboriginal lifestyle to the more American lifestyle explaining that with this transition comes the resulting poor health that has been increasing in the United States. So, some more thoughts come to my mind. First, will the rural villages outside of Irapuato be experiencing the increasing obesity trends? If so, why? What activities are they not doing and what are they doing to cause this? I feel that it is likely that the children are in a rural enough part of Mexico still with heavy traces of "aboriginal" culture and activities. But who knows- I will see when I get there. Nonetheless, I will still need to be sure to rephrase my hypothesis to emphasize more the type of physical activity that is being done and that correlates with decreased or increased stability and posture. So the hypothesis should read more like this "Higher levels of physical activity and longer durations, lead to increased core stability."

  Well, this leads me to realize that I need to rethink my thesis a little bit better. Instead of saying that Mexican children will hav
