In the present study, muscular flexibility and strength were assessed between the pre- and post-tests, comparing each participant with herself. The muscular flexibility and strength variable variations between the pre- and post-tests was compared to the zero value by means of the parametric
test of comparison of an average with unknown σ(paired t-student’s test) with a significance level of 5%. The percentage of strength variations was evaluated, considering on the basis of the pre-test strength measures. Strength variation is equal to the strength on the post-test minus the strength on the pre-test multiplied by 100 and divided by the strength on the pre-test
