Figute 5A-E. Mean (±SD) Ln rMSSD (A), interleukin-6 (IL-6) (B), leucocytes (C), creatine kinase (D), and myoglobin (E) responses for short and long intervals and matched continuous exercise in endurance (left) and sprint type (right) athletes. The differences in changes in time between endurance and sprint athletes expressed as magnitude-based inferences and their likelihood are shown (*possible, **likely, ***very likely, ****most likely. No asterisk means that 90% CL overlapped the thresholds for substantiveness - unclear difference) (see also Methods).
