@RodSiegel I don't think we can quantify W' precisely enough to establish whether it is variable or not? Theoretically it should be modifiable through chronic training interventions but should it be consistent in acute settings when reaching exhaustion in severe domain?

I could never quite get my head around W' being a fixed parameter. Human physiology is far too complex for such simple frameworks 🤔
European Journal of Applied Physiology@EJAP_official

The European Journal of Applied Physiology reports that cyclists maintained higher work output above critical power when work rate was reduced prior to failure. This challenges the notion of W′ as a fixed parameter, showing adaptability in performance. bit.ly/4oDUDFX

Really nice longitudinal research from @TeamDerave reporting that youth track-and-field athletes who trained for a discipline that matched their muscle typology attained a better performance at senior level many years later pubmed.ncbi.nlm.nih.gov/40662927/

New Research Alert Excited to share our latest study in the @JSCRonline Well done Andrew Martin on your 1st PhD study @Phil_Bellinger @clareMINAHAN @MBourne5 journals.lww.com/nsca-jscr/abst… Highlights: Validated RSS profiling protocols tailored for female athletes. Optimal load identified: ~59–72% body mass (BM) for peak power (50%Vdec). Trial distances: 10–30 m for effective profiling. Key Message: Coaches can now personalise resisted sprint loads for female athletes with the aim of enhancing acceleration and sprint performance.

@bowtiedcheetahh @jem_arnold Lots of nuances to BFR but this could be a method to increase metabolic perturbation and provide additional stimulus for adaption in endurance athletes. Somewhat recent SR by Chua et al. 2022

Can mNIRS muscle oxygenation be used to estimate peripheral 🦵training load/stress? Similar to using time >90% VO2max for central 🫀cardiovascular stress A new paper provides some descriptive data for runners performing HIIT and SIT 1/12🧵 (study 🔗 in alt text👇)

Fantastic work from @Phil_Bellinger & co, further advancing our understanding of the physiological responses to training. And a great 🧵 from @jem_arnold unpacking it all 👇

90% of expert coaches and support staff value the use of muscle fiber estimates to individualize training, But 50% claim to be limited in ability to implement. It doesn't have to be that way. 50m sprint + 6 minute run starts you on the path To understanding your squads speed and endurance balance (See athlete A & B). New survey details below ⬇️

Another great @E_C_S_S Congress. Many learnings and most importantly, stronger networks

@JCC_PhD Congrats on the comprehensive study. When you control for initial level of strength (i.e., men are stronger), do the differences between males and females persist? i.e., is it just because the males were stronger and perform more total work that they have greater fatiguability?

Sex differences in performance fatiguability are fascinating. Research shows females are less fatiguable than males in certain exercises. But what about resistance training? 🏋️‍♀️🏋️‍♂️ We just published a study through @EJAP_official to explore this further.

@Gareth_Sandford It would be interesting to see if there was consistency in the type of profiles that the better responders had in the MAS and VIFT groups...

VO2max changes are most consistent within the squad when prescribed with 20% ASR. The variability of outcome with VIFT and MAS works well for some, And worse for others. Reliance on any model has limitation. But what about at low and moderate intensity...

Anaerobic speed reserve application to basketball🏀 is here! If you are interested in conditioning with high intensity interval training then you’ll want to read this new study...

@peter__leo @Alex_Welburn @Thomas_Wackwitz Hi Peter, this project focused on the f200 m exclusively, so our tested cadence range was specific to precisely estimate Pmax and Fopt. Cmax/Tmax would require extrapolation well outside our cadence range so we chose not to report them, not to say that they aren't important

@jem_arnold @Gareth_Sandford Cheers Jem, nice thread and overview. The data points in the figures look very similar but with very different r2/p values? Nonetheless, might support traditional periodization approach - high LIT to increase tolerability/CP followed by increase in HIT for raising VO2max

@Phil_Bellinger @Gareth_Sandford Your second point. Agreed, author's thesis has that. See response from author in this thread. I still need to try to understand better. twitter.com/jem_arnold/sta…
Jem Arnold@jem_arnold

hmm. Thesis concludes non-sig relationship, non-meaningful R² btwn %VO2max & ⬆️VO2max based on Δ% pre-post Conference abstract reports significant and very meaningful R² relationship between same, with ⬆️VO2max in Δml/min/kg
