Effect of physical exercise on lactate, haemoglobin concentration as well as haematocrit, and delta plasma volume (ΔPV) before, after, and 1 hour after exercise.
| Parameter | Preexercise ± S.D |
Postexercise ± S.D |
Recovery (1 h) ± S.D |
|---|---|---|---|
| Lactate (mmol/L) | 2.47 ± 0.78 | 11.19 ± 1.78* | 3.33 ± 0.80# |
| Haemoglobin (g/dL) | 15.44 ± 0.87 | 16.75 ± 0.78** | 15.24 ± 0.87# |
| Haematocrit (%) | 45.56 ± 2.22 | 49.72 ± 2.40** | 44.90 ± 2.46# |
| ΔPV (%) | −14.47 ± 3.95 | 3.02 ± 4.19 |
