p time, difference in means over the competition preparation diet (start, middle and end of phases), p result, division in means between PRO and AMA. Time x division interaction between diet over time and division. Differences in macronutrients and energy measured by repeated measures ANOVA. Statistical significance assumed where p < 0.05
