Concentrations of adenine nucleotides (ATP, ADP, AMP) and inosine nucleotides (IMP) in red blood cells before exercise, after exercise and 30 min of recovery
| Before exercise | After exercise | 30 min of recovery | |
|---|---|---|---|
| ATP (μmol/l RBC) | 1,797.00 ± 158.83 | 1,777.80 ± 130.52 | 1,808.522 ± 155.26 |
| ADP (μmol/l RBC) | 227.42 ± 40.49 | 220.13 ± 42.30 | 189.18 ± 39.57* |
| AMP (μmol/l RBC) | 14.25 ± 2.94 | 13.21 ± 3.09 | 9.77 ± 2.43***,§§ |
| TAN (μmol/l RBC) | 2,038.59 ± 172.87 | 2,010.73 ± 154.92 | 2,006.79 ± 171.29 |
| AEC | 0.93 ± 0.01 | 0.93 ± 0.01 | 0.94 ± 0.009**,§ |
| IMP (μmol/l RBC) | 7.16 ± 1.35 | 8.43 ± 1.86* | 6.82 ± 2.00§ |
| ATP/ADP (μmol/l RBC) | 8.13 ± 1.54 | 8.41 ± 1.53 | 9.91 ± 1.96*,§ |
| ADP/AMP (μmol/l RBC) | 16.06 ± 1.13 | 16.95 ± 1.84 | 19.56 ± 1.67***,§§§ |
Concentrations of ATP, ADP, AMP, TAN and IMP are expressed as μmol/l RBC
Values are given as mean ± SD; n = 22
TAN (total adenine nucleotides) = [ATP] + [ADP]) + [AMP]
AEC (adenylate energy charge) was evaluated according to the formula by Atkinson
AEC = ([ATP] + 0.5[ADP])/([ATP] + [ADP] + [AMP])
* P < 0.01; **P < 0.006; ***P < 0.0001, significantly different from before exercise
