Fig 5. Effects of running 5 km (continuous line) on insulin sensitivity by QUICKI index 1/(log₁₀insulin+log₁₀glucose) compared with a non-exercise day (dashed line) in 17 healthy subjects studied on two separate occasions.

Running took place after the baseline test on the day of the run. Data are means and standard errors. Linear mixed model for analyzing the effect of the race compared with the day of rest: p < 0.0001. *corresponds to p < 0.0001 when comparing QUICKI index before and after the race on the day of the race.
