The Oxygen Equivalent of Lactate Accumulation and Sex: Similar Work–Lactate Slopes in Men and Women Regardless of Body or Fat‐Free Mass Scaling

Methods modulate: protocol choice shapes apparent sex differences in the determination of exercise intensity

Demonstrates that reported sex differences in exercise intensity determination could reflect protocol choices (ramp rate, mode, criteria) rather than true biological differences, …

Maximal glycolytic flux modulates metabolic thresholds independent of maximal oxygen uptake

Shows that maximal glycolytic flux (vLamax) shifts metabolic thresholds independently of VO₂max, challenging threshold models that focus solely on aerobic capacity and supporting a …

Zone 2 Intensity: A Critical Comparison of Individual Variability in Different Submaximal Exercise Intensity Boundaries

Compares individual variability across common Zone 2 intensity definitions (lactate threshold, ventilatory threshold, fat oxidation peak, etc.) in trained athletes, showing that …
