New paper in EJAP: In trained cyclists, vLaₚₑₐₖ had stronger associations with metabolic thresholds than sprint power — suggesting that the glycolytic signature of the sprint matters for endurance profiling. @billysperlich.bsky.social @peter-leo.bsky.social https://doi.org/10.1007/s00421-026-06270-1

Maximal glycolytic flux modulates metabolic thresholds independent of maximal oxygen uptake - European Journal of Applied Physiology

Purpose This study examined how maximal glycolytic flux, indexed by the peak lactate accumulation rate (vLapeak) from a 15-s sprint, relates to lactate- and gas-exchange derived endurance thresholds a...

Not all important science confirms a hypothesis. Null findings are a critical part of the research process—but they’re often left unpublished. We’re highlighting why (and how to change that) in the latest edition of our new FASEB Publications LinkedIn Newsletter 👇 buff.ly/mSBPnUm

Call for Letters on Durability, Fatigability, Resilience, and Repeatability

<p>The <em>Journal of Applied Physiology</em> publishes original papers that deal with diverse areas of research in applied physiology, especially those papers emphasizing adaptive and integrative mechanisms. Adaptive physiology includes 1) inherent adaptations such as those related to development, aging, and pathophysiological conditions and 2) adaptations to the external environment such as those occurring with exercise, microgravity, hypoxia, hypo- and hyperbaria, and hypo- and hyperthermic conditions. Integrative physiology includes 1) horizontal integration across organ systems and 2) vertical integration from molecule to cell to organ. In all areas of applied physiology, the use of cutting-edge techniques including molecular and cellular biology is strongly encouraged.</p><p>The wide scientific span of the Journal rests on physiology as its keystone. However, the boundaries of physiology have enlarged as demarcations between concepts and techniques in the physiological, pharmacological, and biochemical sciences become increasingly blurred. Moreover, theoretical articles on research at any level of biological organization ranging from molecules to humans fall within the broad scope of the Journal. Papers dealing with topics in other basic sciences that impinge on physiology are also welcome.</p>

Experiment and learn your response! Another paper on zone 2 training that neatly demonstrates the great variety in responses of differen intensity markers. In my opinion, yet another reminder for why you shouldn’t rely on one intensity marker (or generic %HR or %FTP ranges).

And an experiment observing reliability & agreement of common methods to estimate the upper boundary of "zone 2" from HR, lactate, ventilation, RPE, etc. Meixner B, et al. 2025. Zone 2 Intensity: A Critical Comparison of Individual Variability... onlinelibrary.wiley.com/doi/full/10....

A waterfall plot showing individual participant observations and distributions for 9 methods of estimating the first metabolic threshold, as the ceiling for "zone 2". Those methods are: 72% HRmax, Fatmax, BLa 1.5, 65% VO2max, BLa baseline+0.5, ventilatory threshold 1, HR 62%, BLa 2.0, BLa 2.5. The range of observations extends from approximately 20% peak incremental power output, up to 75% PPO, revealing how heterogenous each estimate of the first metabolic threhsold is between individuals. The interpretation being that no one method is "real" or "best". Each method has trade-offs that may be more or less appropriate for each individual athlete's context: their fitness, capabilities, their sport and performance goals, access to equipment, desired information and application in training, and their personal preferences.

A good editorial attempting to reconcile expert opinions from a physiological & academic perspective on the popular meme of "zone 2" training What Is “Zone 2 Training”?: Experts’ Viewpoint on Definition, Training Methods, and Expected Adaptations. journals.humankinetics.com/view/journal...

A schematic highlighting two common training intensity zone models, one with 3-zones, the other with 5-zones. "zone 2" refers, confusingly, to zone 1 in a 3-zone model, or zone 2 in a 5+ zone model, i.e. under the first metabolic threshold, estimated as the first lactate or ventilatory threshold, Fatmax, or other methods.

Our recent study included the effects of creatine supplementation on vlamax-testing. The results imply that some athletes may be limited by their metabolism while others could be limited by the testing setup. Read more about it here: cdn.nutrition.org/article/S247... @billysperlich.bsky.social

Supplementation of Creatine Monohydrate improves sprint performance but has no effect on glycolytic contribution: A Non-Randomized, Placebo-Controlled Crossover Trial in Trained Cyclists

Summary: Creatine loading supplementation increases 15s-work while hinting at different mechanisms involved in its effects on individual limitations to 15s-work.
