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.

2/
The gender gap in performance is present across all world records, 10.0% ±2.94 between men & women for all events. 

The gap ranges from 5.5% in 800m freestyle, 7% for speed skating, 8.7% cycling, 10.7% in running, & 18.8% in long jump.

Testosterone does not discriminate.

In Olympic weightlifting from the age of 10 to 12 years a gender gap emerges with a difference of 11.7% between sex's at the age of 14.

At 25 the gender gap rises to 23.6% for lighter athlete's (69kg) and increases to 29.9% at 81kg.

The #IOC ask for "disproportionate advantage" this disproportionate sex advantage is clear as cited via peer review academic literature.

Male's have a clear advantage over female's. If male's are left to compete against female's in sport elite female's will seize to exist.

Tucker and Santos-Concejero highlight the difference in males and females WR's is not continuing to close but remains vast on average male-female gap is currently 11.2 ± 1.0% for all running events.

Comparison of female WR'S vs. Number of Males quicker.

6052 males have ran quicker than the women's 100m WR of 10.49s.

The women's 800m world lead time of 1.55.04 for 2021 has been bettered by 232 males in the UK alone in 2021 including U17's.

7/
Women's Tokyo Olympic Long Jump was won in 7.00m vs. Males was won in 8.41m. A difference of 1.41m (20.14%)

Women's Tokyo Olympic Long Jump was won in 2.04m vs. Males was won in 2.37m. A difference of 0.33m (16.17%).

8/
In strength events males significantly outperform women even when women have a weight advantage.

Tokyo 2021 Olympic weightlifting:

Males 61kg combined lift = 313kg Vs. Females 64kg combined lift = 236kg. A difference of 77kg, 32.63%!

Females 87kg+ combine=282kg
31kg (10.99%)
A little thread highlighting a small degree of the "disproportionate advantage" male's have over female's. This evidence is easily identifiable highlighting the fallacy of the IOC's guidelines.

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.

1/ Image
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.

2/
You are forced with the dilemma after a few years of battling realising that many athlete's are not on a level playing feild.

Neopros UK their training to new heights for little success and end up battling over training. Training harder and harder with little success.

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.

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.

2/
As Shane's squad under went testing for nandrolone in an unacredited WADA lab against WADA's rules as few as 10 British Cycling staff were aware, including the gang: Brailsford, Sutton, Peters and Freeman.

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.

Britain's CJ Ujah part of the Olympic 4x100m relay team who won the silver medal at the Tokyo Olympics has returned an AAF for the Selective Androgen Receptor Modulator's (SARM'S) Ostarine & S-23. He is likely to claim a contaminated supplement is the reason behind his AAF

@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.

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.

Thread 1/
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.

researchgate.net/publication/33…

2/
In 1966 the USOC organised a conference where the consensuses of principles of altitude training were developed to enhance athletic performance.

The USSR & USA developed sports centres at altitude in the search of how best to prepare athletes for competitions at altitude.
