ATP AND CP STORES

Rushall notes (1990).

A muscle cell stores about 6 mM of ATP per kilogram of muscle. That amount is sufficient to sustain one second of sprinting and is therefore used for single maximum efforts. However, there is sufficient CP stored to support about 6 seconds of further sprinting (CP is used to resynthesize ATP after it has been broken down by muscular contraction). These are the primary fuels for very short or single maximum efforts.
