Energy balance
Resistance exercise preferentially increases circulating lactate and purine metabolites (inosine, hypoxanthine, xanthine) compared to endurance exercise, suggesting a higher demand for glycolytic ATP turnover and nucleotide degradation during anaerobic efforts.
Resistance training creates a unique metabolic environment with high lactate and purine breakdown. This signals your body to adapt to high-intensity demands. Embrace the burn as a sign of effective glycolytic training, not just fatigue.
GoodSupportsHIGH confidence
Conversely, RE more potently induced circulating lactate and AKG relative to EE... As expected, degradation products such as inosine, hypoxanthine, and xanthine are increased in response to either mode of exercise but considerably more so by RE.
Why this rating
Clear statistical separation in metabolomic profiles between RE and EE for these specific compounds.

More from this paper
- Acute resistance exercise and endurance exercise produce distinct, mode-specific plasma metabolomic signatures, with resistance exercise preferentially increasing nucleotide breakdown products and lactate, while endurance exercise preferentially increasing lipid metabolites and ketone bodies.Good
- Endurance exercise significantly increases circulating beta-hydroxybutyrate (BHBA), which acts as a signaling molecule that inhibits histone deacetylases (HDACs) and activates the HCA2 receptor, promoting anti-inflammatory and neuroprotective effects.Good
