🆕 paper on validity & reliability of threshold determination using #heartratevariabiliy in #rowers. Second threshold works robustly.👏 @steffen_held, @LudwigRappelt, @TNWiedenmann, Julius Rommelmann & @G_Ron_Woods published in the @EurJSportSci (IF: 3.0) drive.google.com/file/d/1GkqHlO…

👏👏👏Proud to have a young investigator in my team - congratulations to @LudwigRappelt for such a big achievement at the German sports science conference #GEST25! Thanks to @SpoMedSb , @Brina1812 and #DVSsportwissenschaft for hosting!

@JDruns Are you sure that these data relate to LT1 and not LT2?

Preliminary results from a new project: LT1 occurs at 69-94% HRmax in 9 out of 10 runners. Data pooled from 7 studies totaling 140 subjects. Results for LT2, plus %HRR and %VO2max coming soon!

@EamonnFlanagan @DKalkounis here is a figure from my lecturing slides. BFR might be a promising tool for endurance sports.

@DKalkounis Yes. Check out @steffen_held work in rowing: specific interventions with occlusion and low intensity rowing showing improvement in VO2max. Also a number of studies in stationary cycling.

New research: Blood Flow Restriction Training The 30-15-15-15 protocol (@ 30%1RM) is equally effective at developing hamstring strength and muscle thickness as high load training (70% 1RM x 12 reps) 🔹32 subjects 🔹6 wk intervention (x3/wk) 🔹Prone leg curl exercise

🚨 NEW PAPER 🚨 showing that post-activation performance enhancement does not exceed warm-up effects on subsequent jumping. Congrats 👏 🎉 👏 @LudwigRappelt from @SpohoKoeln ! FULL paper here 👇👇👇 frontiersin.org/journals/physi…

🚨 Congrats @LudwigRappelt from @SpohoKoeln & @Uni_Wuppertal & co-authors (@steffen_held, @FlorianMicke, @TNWiedenmann, @janphilip_d) on your PhD-paper in @JRehabilMed dealing with "lower body electromyostimulation in elite wheelchair basketball players" drive.google.com/file/d/1jRc3OX…

@NBTiller @OliverFaude @JamesSteeleII @ExPhysStudent @Ekkekakis @TenanATC @LarsDonath …additionally assumed a high(er) correlations among repeated measures (about 0.8). With a moderate partial eta squared (about 0.08), one should then arrive at this sample size range.

@NBTiller @OliverFaude @JamesSteeleII @ExPhysStudent @Ekkekakis @TenanATC @LarsDonath I agree, looking back at it now, we could have provided a bit more precise information. The power analysis is based on a repeated measures ANOVA, which we also used for the analysis of our data. Thereby, the SMD might be misleading. Based on the crossover design, we…

A sample size of n=13 from moderate effects and power of 0.95? I'm finding it impossible to recreate. Thoughts? @Ekkekakis @JamesSteeleII @TenanATC

Uphill ⛰️ HIIT 🥵 🏃‍♀️is an effective method to increase time spent above >90% VO2max: frontiersin.org/journals/physi…

Low-intensity rowing with #BFR enhances #VO2max in #Rowing, marking a promising approach for boosting aerobic capacity. Thanks to all contributors @LarsDonath @LudwigRappelt @TNWiedenmann @janphilip_d @rudern @Deutschland8er @BISp_Bund

@EamonnFlanagan @carragher_paul 👍 finally published pubmed.ncbi.nlm.nih.gov/38489574/

@carragher_paul Steffen Held has done interesting work on this in rowing @steffen_held with another paper to come soon I think ?

🧑🏼‍🎓Successful PhD defense by @tobibaum supervized by @KlattStefanie. Thanks for sharing time, fruitful discussions and publishing together. All the best for your future with @CombatIq!

@JDeLeo @LarsDonath @LudwigRappelt @BISp_Bund Up to now not. But we are in preparation to publish parts of this data (in English).

@steffen_held @LarsDonath @LudwigRappelt @BISp_Bund Is there an English version available?
