Figure 6. Utilisation of subcellular glycogen in type 1 and type 2 fibres during repeated high‐intensity intermittent exercise.

Figure 6

Total glycogen based on all subcellular pools (A), intermyofibrillar glycogen (IMF) (B), intramyofibrillar glycogen (Intra) (C), subsarcolemmal glycogen (SS) determined pre‐exercise (PRE) and after exercise period 1 (P‐EX1) and after exercise period 3 (P‐EX3) (D). n = 17. Data are presented as geometric means and 95% CI. *Significant difference in glycogen utilisation between fibre types from pre to post EX1, P ≤ 0.05. Main effects of time were present for all subcellular glycogen pools in each fibre type for baseline to EX1 and for EX1 to EX2+EX3 (P ≤ 0.05).
