133rd KIW Research Note is Out! Dr Raphaël Faiss @wattsnow explains: 1) What is RSH 2) The Relative Performance Gains 3) The Physiological Rationales 👇 knowledgeiswatt.substack.com/p/the-science-…

Pourquoi les athlètes en partance pour les Jeux d'hiver de Milan s'entraînent au chaud, à des températures supérieures à 35°. Les explications de Raphaël Faiss @wattsnow, dans la chronique mensuelle des chercheurs de l'@ISSULausanne. | via @letemps letemps.ch/sport/la-chale…

@GiuseppeLe85 the responses are intensity dependent. You need to recruit fast twitch fibers !

@wattsnow Why.only sprint and not estensive Z2/3. Training?

It is out! Rather proud that we started with the first RSH study in 2011. Now most of the elite athletes i talk to tell me they do some form of RSH

Just in time, as MTB world champs are held in Kigali, above 1500m asl, later this month :) Thank you @wattsnow and @DebevecTadej for the supervision!

Great sharing experience with a Masterclass on altitude training for the dutch olympic trainers @Papendal Thank you @BernadetvanOs , @WouterRuchtie & @nocnsf for inviting me, it was inspiring !

Good news! Two of our articles received enough views to reach the Most Viewed status. Read them here: onlinelibrary.wiley.com/doi/full/10.10… …iencejournals.onlinelibrary.wiley.com/doi/full/10.10… #TopViewedArticle @wileyinresearch @unil

Latest manuscript accepted in @BiolSport : Substances referred to as 'brain doping': prohibited or not in sports? with a great collaboration with my Polish 🇵🇱 colleagues. Soon online ahead of print!

@DebevecTadej @EHSM_Magglingen and to elevate our knowledge

@wattsnow @EHSM_Magglingen Just high enough location for today apparently ☀️ 🤩

Back in Magglingen @EHSM_Magglingen for the Swiss Sport Sciences Society #SGS #4s conference. Moderating and presenting the altitude training session !

@Nyborger_Nybo agree 💯 % on that

@wattsnow but still more precise to measure it :-)

Interesting read: “Hemoglobin mass is accurately predicted in endurance athletes” great collaboration with great Polish colleagues!

Excellent way to start the year with a paper accepted: “Hemoglobin Mass is accurately predicted in Endurance Athletes” just accepted in @JSportsSci Excellent collaboration with @pkasiak1 & team

@sweatscience we actually did investigate blood profiles in breath-holders. We found that regular breath-hold training does not induce significant variations over one year for the hematological module of the ABP pubmed.ncbi.nlm.nih.gov/34498826/

Repeated breath holds produce an effect "similar to blood doping": the spleen contracts to release a reserve of fresh oxygen-carrying red blood cells. Could this boost running endurance? Previous research has been iffy, but a new study is more optimistic. outsideonline.com/health/trainin…

@wattsnow @Nyborger_Nybo @morten_hostrup @iljukov @honestsport_ew @sweatscience @VictorConte @RAnneShirley @ShalayaKipp @TStellingwerff @ChrisMinson Look at the studies in smokers from many years ago… a dose after training and then before bed could generate a 5-10% increase in Hb.

Michael Kalinski’s work on ergogenic aids research in the USSR is widely recognized. In our latest publication, we focus on the studies of blood transfusions in Soviet sports. These studies informed recommendations for using blood transfusions during Olympic Games, which played a role in the Soviet Union’s significant medal success at the 1976 Innsbruck and Montreal Olympics, as well as the 1980 Lake Placid Games. While the topic is controversial, it is worth noting that blood transfusions were only banned in sports in 1985, following a scandal involving American cyclists at the 1984 Los Angeles Olympics. We hope our publication contributes a meaningful addition to the history of global sports. researchgate.net/publication/38…

@DrMJoyner @Nyborger_Nybo @morten_hostrup @iljukov @honestsport_ew @sweatscience @VictorConte @RAnneShirley @ShalayaKipp @TStellingwerff @ChrisMinson definitely an underused tool for performance improvement 😁 pmc.ncbi.nlm.nih.gov/articles/PMC30…

@honestsport_ew @iljukov @DrMJoyner @sweatscience @VictorConte @RAnneShirley @ShalayaKipp @TStellingwerff @ChrisMinson @Nyborger_Nybo the implementation in 08.2023 of the monitoring of IGF-1 and P3NP as part of the endocrine module of the Athlete Biological Passport is a step towards detection of GH doping as variations are very sensitive to it

@iljukov @DrMJoyner @sweatscience @wattsnow @VictorConte @RAnneShirley @ShalayaKipp @TStellingwerff @ChrisMinson @Nyborger_Nybo I find it really interesting that labs effectively can't detect AICAR, a true performance enhancer. I don't recall a single AICAR positive so I wonder how prevalent its use is, along with more new age peptides) and of course HGH which is still hard to detect past a few hours).

@honestsport_ew @iljukov @DrMJoyner @sweatscience @VictorConte @RAnneShirley @ShalayaKipp @TStellingwerff @ChrisMinson @Nyborger_Nybo AICAR is being detected and looked for for more than 15 years. wada-ama.org/en/resources/s… and its synthetic origin is now determined by IRMS in the labs (pubmed.ncbi.nlm.nih.gov/29032594/)

@Nyborger_Nybo @morten_hostrup @DrMJoyner @iljukov @honestsport_ew @sweatscience @VictorConte @RAnneShirley @ShalayaKipp @TStellingwerff @ChrisMinson check details here: …iencejournals.onlinelibrary.wiley.com/doi/full/10.10…

@Nyborger_Nybo @morten_hostrup @DrMJoyner @iljukov @honestsport_ew @sweatscience @VictorConte @RAnneShirley @ShalayaKipp @TStellingwerff @ChrisMinson half life of CO (for elimination) is ~300 min. Less when exercising because of a higher minute ventilation. SO the transient decrease in CaO2 is maintained longer. However, vs. a N2 House or hypoxic tent, the effect is not better with CO for an increased erythropoiesis.
