The present study examined the reliability and validity of in vivo vastus lateralis (VL) fascicle length (L(f)) assessment by extended field-of-view ultrasonography (EFOV US). Intraexperimenter and intersession reliability of EFOV US were tested. Further, L(f) measured from EFOV US images were compared to L(f) measured from static US images (6-cm FOV) where out-of-field fascicle portions were t...

one of the models that can be used to study the relationship between boolean random sets and explanatory variables is growth regression model which is defined by generalization of boolean model and permitting its grains distribution to be dependent on the values of explanatory variables. this model can be used in the study of behavior of boolean random sets when their coverage regions variation...
