Is Assefa a super responder to ‘super shoes’?

What does the scientific literature tell us about the effects of super shoes on running economy and race performance? Let’s investigate.

Long thread 🧵 *** Disclaimer***

Without directly testing Assefa in the laboratory we can not determine the effect of super shoes on her running economy and other physiological markers. However, we can explore what the academic literature may suggest is possible and/or not possible. 2/

Interesting point here. A good British standard 65min half runner running 100mpw religiously weighed 73kg.

More than 20kg heavier than world class elite Africans.

This is one of the reasons why East Africans dominate endurance running.

In a brilliant review of running economy (RE) by Barns & Kilding 2015 discuss numerous factors influencing RE.

RE is multifactorial but an interesting factor discussed is how RE reduces with reduced distal leg mass.

The IOC trans guidelines are very weak.

The performance benefits of testosterone do not discriminate between sport.

On average males have a performance benefit of 11.2% (± 1. 25) across all running events & 19.0% (± 2.57) for all jumping events.

The gender gap exists across all running distances as shown by Thibault et al (2010) study showsthe smallest margin in running events of 6.5% in the 100m but the largest difference 13.96% I the 4x100m.

How was the person able to get away with doping if so many knew? These actions encourage doping and are complicit.

If many people knew why did no one speak out and stop this before it grew.

I have sympathy for many pro athlete's in this situation where doping is systemic to succeed.

You train your whole life to achieve your life long dreams of becoming a pro athlete. Only once you get there you realise the game is rigged.

More suspicious events from British Cycling & UKAD.

Weeks before the London 2012 games a world class cyclist rode away from an anti-doping control officer disappearing out of sight for over an hour.

Thread with more of the same key players involved.

dailymail.co.uk/sport/sportsne… Both the rider in question who rode away and the group of riders in question regarding the nandrolone tests where both high natural occurring levels and contamination were ruled out were part of Shane Sutton's squad of riders.

One of anti-doping's biggest challenges is proving how a substance entered an athlete's body. Subsequently, the responsibility has been placed upon the athlete to prove how a substance has came into their body under WADA's Code of 'strict liability'.

Thread 1/ With anti-doping labs analytical sensitivity improving, athletes testing positive due to contamination of supplements for trace amounts of PED's offers a real concern to both athletes and the anti-doping authorities.

@WorldAthletics time for a periodic review of the DSD regulations which currently restrict 46XY female athletes who have testes & testosterone levels in the male range (7.7 - 29.4nmol/L) currently only restricting participation in events over the 400m-1500m.

Thread 1/ The performance benefits of testosterone do not discriminate between running distances.

On average males have a performance benefit of 11.2% (± 1. 25) across all running events & 19.0% (± 2.57) for all jumping events.

Olympic 100m champion & double gold medalist Marcell Jacobs "nutritionist" who immediately claimed Jacobs transformation was due to him is linked with Italian police investigation 'Operation Muscle Bound' for supplying HGH, testosterone and anabolic steroids.

Jacobs who was not currently in the AIU athlete testing pool rapidly improved his performance from a PB of 10.03s set in 2019, with a SB of 10.10s to take the Olympic title in 9.80s.

Jacobs has improved by 3% in less than 12 months at the age of 26.

Altitude is the new reason for improved performances and faster times across the peleton claims San Milan.

Since the 1968 Mexico Olympics altitude training has been systematically applied in preparation to enhance athletic performance.

Altitude training methodology was developed during the 70s & 80s with mass adoption in the 90s across most of the world.

"cycling's transformed...trust what we are seeing" Gianetti

How can we believe Gianetti's statement when numerous teams have staff members ingrained in cycling's doping past.

As a rider Gianetti collapsed during the 1998 Tour of Romandie with multiple organ failure after suspected use of a experimental drug PFC (perfluorocarbon) a blood substitute.
