2x2 anova, no interaction


i want to compare male and female adults kinematics while normal walking and perturbation. I do 2x2 anova. The example graph is below. Both effects (gender and perturbation occurance) are significant but interaction is not. How can I get exact information where exactly are statistically significant informations? Can I do post hoc test for interaction If interaction is not significant? I read many different posts and I am very confused now so I would be grateful for claryfying this ;)
