	POSITIVE PDB OR (95%CI)	NEUTRAL PDB OR (95%CI)
GENERAL OPINION ABOUT TRAINING * #
Technique is an important part of my training	1.06 (0.32-5.12)	0.45 (0.12-0.78)
Training is monotonous and lacks diversity	1.82 (1.41-5.11)	1. 55 (0.65-7.39)
Training is mostly oriented toward volume	2.76 (1.11-7.12)	1. 64 (1.09-3.12)
INTENSITY HIGH WHEN I HAVE TO SWIM … #
… >6 km per session	2.17 (0.51-9.32)	1.47 (0.44-4.98)
… >2 km in one sequence	0.19 (0.04-1.04)	0.49 (0.09-2.78)
… repeated sets of maximal intensity	2.43 (0.59-10.10)	2.31 (0.66-8.15)
… different relays while being highly focused on stroke-technique, -speed, and -force	0.18 (0.02-0.62)	0.86 (0.25-2.96)
… sets I have never/rarely performed before	0.89 (0.09-8.56)	0.38 (0.09-1.75)
Intensity is high but with no specific reason	0.25 (0.02-3.31)	0.09 (0.01-0.65)
COACHING STRATEGY #
Coach frequently explains the training aims	0.21 (0.04-0.81)	0.1 (0.01-0.67)
Coach overviews and discuss the quality of (my) execution of specific tasks	0.41 (0.02-0.81)	0.19 (0.11-0.98)
Coach is very strict and rigid	0.98 (0.04-7.11)	1.05 (0.09-3.65)
Discipline is an important part of our training regime	1.41 (0.23-9.80)	1.98 (0.41-7.18)
Coach pushes me very hard	0.89 (0.11-6.85)	0.45 (0.02-5.14)
Sometimes, I don’t know what does the Coach wants me to do in training	1.31 (0.98-1.99)	1.67 (1.01-4.21)
VOLUME OF TRAINING CONT	1.03 (0.65-1.66)	0.71 (0.45-1.12)
TECHNIQUE (APPROXIMATION) CONT	0.14 (0.03-0.96)	0.12 (0.01-0.81)
