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.

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.
