The tree regression analysis to predict DOMS intensity.
A regression tree analysis was set up to predict DOMS pain intensity by anxiety score below or above 46 and sex. The numbers in the circles indicate the level of statistical significance (P); and the numbers in the rectangular boxes reflect the total number of cases for that outcome (n) and the mean of pain intensity (y).

Significant interaction (time by group) for PPTd.
The measurement of pain pressure threshold (mean±standard error) on the Deltoid (PPTd) showed that responders (black solid line) demonstrated a significant decrease in PPTd following eccentric exercise. PPT differences between the sessions were 101kPa for responders; 63 kPa for non-responders (brake black line); and -3kPa for the control group who did not perform the exercise (grey solid line).

The tree decision analysis to predict DOMS responders.
Decision tree analysis set up to predict DOMS responders (VAS≥3) by PPTf (pressure pain threshold in the forearm), below or above 378kPA, and anxiety score below or above 46. The numbers in the circles reflect the level of statistical significance (P); numbers in the rectangular boxes reflect the total number of cases for that outcome (n) and the probability (y) to become a non-responder (first number) or DOMS–responder (second number).
