...) was a predictor of V̇ O 2 ,max . In turn, V̇ O 2 ,max predicted the maximum number of four-legged push-ups per bout ( B =0.39). In path analysis, log likelihood ratio tests indicated no direct paths from lower-level traits to behavior, supporting the idea that morphology, in the broad sense, only affects behavior...

...) a multiple regression using the enzymatic activities as predictor variables, and metabolic rate as dependent variable; and (3) a structural equation model(i.e. path analysis) to estimate the association between variables from their covariance structure. With this experiment, we addressed the following...
