Effect of 24 sessions of high-intensity aerobic interval training carried out at either high or moderate frequency, a randomized trial.

We also found a 25% increase in activity in the HF group (from 0.30±0.12 to 0.37±0.11 μmol · ml −1 · min −1 ·mg −1 protein), but this improvement did not reach statistical significance (p = 0.185; between group difference p = 0.009).
