Duration of endurance running [min/week]		0.014			0.034
Frequency of endurance running [TS/week]	2.708	0.679	0.789	3.985	<0.001
Frequency of HIIT [TS/week]		1.425			<0.001
Duration of complementary endurance [min/week]	0.016	0.005	0.373	3.290	0.002
Duration of regeneration [min/week]	0.048	0.020	0.297	2.376	0.022
Monotony in total duration [index]	1.305	0.436	0.297	2.993	0.004
