Fig. 2From: Should I Rest or Should I Go Now? A Randomized Cross-Over Trial Comparing Fixed and Self-Selected Rest Durations in High-Intensity Interval Training Cycling SessionsSelf-selected rest durations between the nine intervals. The thin lines represent self-selected rest durations by the cyclists, whereas the thick lines and error bands represent a GAMM-based estimation of the average rest duration and their 95% CIs, respectively. A Comparison between the fixed and SS conditions for 24 cyclists. The red horizontal line represents the 90-s fixed rest duration allocated in the fixed condition. B Comparison between the test (blue) and retest (yellow) in a subsample of 10 cyclists, under the SS conditionBack to article page
