Results The most significant variables as predictors of youths' sports attitudes were the paternal cognition on sports (Beta=0.757,t=12.065,P<0.01) and the maternal affective dispositions (Beta=0.154,t=2.461,P<0.05); the most significant variable as predictor of male youths' sports attitudes was the paternal sports attitudes(Beta=0.473,t=2.019,P<0.05),while the most significant variable as predictor of female youths' sports attitudes was the maternal sports attitudes(Beta=0.538,t=2.723,P<0.01); the most significant variable as predictor of male youths' sports behaviors was the paternal sports behaviors (Beta=0.382,t=2.337,P<0.05),while the most significant variable as predictor of female youths' sports behaviors was the maternal sports behaviors(Beta=0.332,t=2.790,P<0.01).
