FIG 2.

Training response to SIT, ET and CG for VLa_max, VO_2max and PMLSS.

Note: Inter-participant variability is large for all groups and all parameters. But all participants of the SIT respond with reduction of VLa_max (left). All participants of the ET respond with increase of VO_2max (middle) and ET and SIT respond with increase of PMLSS after six weeks (right). Abbreviations: CG denotes control group; ET endurance training; PMLSS power in calculated maximal lactate steady state; SIT sprint interval training ; VLa_max maximal lactate production rate; VO_2max maximum oxygen consumption at maximum load.
