A slow ATP recovery rate is probably caused by a decrease in the total pool of adenine nucleotides associated with the formation of IMP and the excretion of its metabolites, see (Sahlin & Broberg, 1990) <cite>4</cite>.

Table from (Hellsten et al., 1999) <cite>7</cite>, Skeletal muscle concentrations of adenine nucleotides. AMP is decreased at the end of the exercise compared to rest, while AMP free is increased. At the same time, IMP rises, perhaps that is why AMP decreases (?)

=== Dynamics of glycolysis after cessation of exercise ===

Figure from (Schmitz et al., 2010) <cite>8</cite>, HMP recovery dynamics. “First, we performed high time resolution dynamic in vivo measurements of the turnover of phosphorylated glycolytic metabolites (hexose monophosphates; HMP) in human leg muscle after exhaustive exercise using 31P NMR spectroscopy. Next, the Lambeth & Kushmerick computational model of glycolysis in muscle was used as a platform to investigate if current knowledge of glycolytic flux and concentration control incorporated in the model was sufficient to explain the measured HMP dynamics (Lambeth & Kushmerick, 2002)”.
