Higher doses of caffeine (8 mg • kg -1) increase lactate dehydrogenase (LDH) levels compared to lower doses and placebo.
Higher caffeine doses may lead to increased metabolic stress, which could be beneficial for certain training adaptations.
StrongSupportsmedium confidence
The LDH levels were significantly higher in CF2 after the third exercise compared to CG and CF1 (229.1 ± 8.3 U/L to 179.3 ± 11.4 U/L and 229.1 ± 8.3 U/L to 220 229.1 ± 13.2 U/L with p=0.001).
