PRE-POST Training effects #132

Closed asansix closed 3 years ago

asansix commented 4 years ago

Hi Todd,

I have 2 groups of 10 participants that performed countermovement jump before and after (PRE – POST) two different interventions. I have the force-time and velocity-time curves. I want to know, the effect of each group after the intervention (within-subjects) and the interaction between the training effects. I used Matlab software and I conducted the SPM1d_anova2onerm_2x2 analysis, is it ok?

The results showed no interaction but there were differences in the main B effect. Then, in order to know the differences after the intervention for each group I conducted the SPM1d_ttest_paired, is it ok?

The paired t-test showed no differences in one intervention group but showed differences in the other intervention group.

Paired t-test Group B velocity-time curve ANOVA 2x2 Velocity-time curves Paired t-test Group A velocity-time curve

Thank you so much for all your contributions and the facilities given in the web.

Alberto.

Hi Alberto, Using spm1d.stats.anova2onerm is fine if the two interventions involved different participants. Everything else sounds good! Todd
