This essay will focus on the discussion the reciprocal causal relationship between children’s weight status and motor development or lack of thereafter.

The amount of missing data and differences in the sample size; baseline (n= 2517) to the final measure (n= 754) was a major drawbacks of this study as the result may limit the generalizability of the findings.

As suggested by Lopes et al., the level of gross motor coordination significantly predicts the changes in the subcutaneous adiposity;

 [c3]raija’s comments:
-Â Â Â Â Â Â Critic the research: in relation to my topic
-Â Â Â Â Â Â what did they
-Â Â Â Â Â IS BMI a reliable and valid measure in that age group
o  Critic the use of BMI
-Â Â Â Â Â KTK battery- commonly used; but validated for this age group?
-Â Â Â Â Â mention how they aassesed
-     commonly used; assessment –
-Â Â Â Â Â statisitical analysis:
-Â Â Â Â Â anlysis of the
-Â Â Â Â Â where it was done?
-Â Â Â Â Â Culturally driven
-Â Â Â Â Â Â Bring multiple researchers together; a few to address the main issues thoroughly
-Â Â Â Â Â Cheng et al and Okley
Â
-Â Â Â Â Â SO WHAT AT THE END:
Â
-Â Â Â Â Â This found this and while the other found something why? Desing difference?
 [c4]HELP! REFERRING TO THE TWO-FOLD CONCLUSION, THIS ONE HERE SUPPORTS THIS SUB-THESIS AND THE SECOND CONCLUSION SUPPORTS MY 2ND SUBTHESIS… HOW SHOULD I INCORPORATE THAT
-Â Â Â Â Â Â [c5]Research approaching from outer disciplinary (social/ psychological)
-Â Â Â Â Â Need to PT intervention? Is there PT intervention and how effective is it?Â
