Muscle Metabolism and Performance During Simulated Peak-Intensity Periods Occurring Early and Late in a Soccer-Specific Exercise Protocol in Well-Trained Male Players.

However, the interaction effect between time and peak period did not reach statistical significance ( p = 0.115), indicating that the change in glycogen from pre to post was not different between the two peak periods despite differences in absolute glycogen utilization levels (decrease in PP1 by 62 ± 46 mmol kg −1 dw from 338 ± 55 to 276 ± 70 and by 25 ± 37 mmol kg −1 dw in PP2 from 206 ± 51 to 180 ± 75, see Figure 2A,B ).
