Dr. Sands on the “twisties”

The “twisties” phenomenon is real.

I’ve experienced it myself and have had several national team gymnasts who have gone through it as well.

I see two dangers:

(1) over medicalizing/psychologizing the issue and (2) giving an invisible symptom as a fairly easy excuse to avoid training and competing.

Medicalizing/psychologizing: this phenomenon is not a “mental health” problem. This is a problem of spatial orientation.

Unfortunately, we know too little about human spatial orientation to be very definitive.

I tried studying spatial orientation while at Utah because of this issue and the use of the term “blacking-out” to describe the same thing that too often occurs on the trampoline.

Unfortunately, a sport-oriented problem like this does not get funding.

While a magnified stress response may be a partial cause, I can tell you that you don’t have to be highly stressed to experience it.

Physicians studying trampoline injuries found that the majority of serious injuries occurred among highly trained athletes and dead-center in the middle of the bed (i.e., they didn’t fall off). The physicians indicated that they thought the trampolinist “blacked out.” However, there is no real loss of consciousness, just orientation.

Moreover, it can be scary as hell when it happens.

Spatial orientation while twisting and somersaulting can be a serious challenge to the integration of the vestibular apparatus, vision, and kinesthesis.

For example: if you stand upright and take your right arm, bend the elbow 90 degrees so that the hand is in front of you, and hold one finger so that it points upward; then rotate your hand in a largish horizontal circle keeping the finger pointing upward. Let’s say you decided to rotate the hand so that it makes a counterclockwise circle as you view it from above (looking down at the circle), if you keep the hand circling counterclockwise while you simultaneously raise your arm/hand so that it circles above your head you will note that the hand is now turning in a clockwise direction. Your brain knows the difference between clockwise and counterclockwise rotation, and you can probably picture that the somersaulting gymnast spins a twist in one direction while going from “right-side-up” to “upside-down” during a somersault. Combining the two orientations results in motor control problems like you experience when trying to rub you stomach and pat your head.

Blindfolded athletes can tell which direction they’re spinning (twisting) while standing upright. However, sometimes they have trouble telling such directions when they are inverted suddenly.

Obviously, a gymnast must pass from an upright body orientation to an inverted body orientation sometimes through two or three somersaults while twisting.

Finally, the loss of spatial orientation can be somewhat “sticky” and remain with an athlete from minutes to months.

Here are some references from work I did on spatial orientation:

2. As for the malingering problem, I’m not sure where to go.

I definitely don’t have any magic fixes. However, too often I’ve found that when these symptoms arise, the athlete’s anxiety can certainly be blamed, but much of the anxiety comes from poor preparation.

I suspect that if athletes are prepared “better” there would be fewer such problems. Moreover, I’d like to encourage coaches to investigate the problem thoroughly before jumping to the idea that the athlete is lazy or unmotivated.

Simone withdrew from Vault & Bars

MyKayla Skinner will replace her on Vault.

Melanie de Jesus dos Santos will go in on Bars.

Kara Eaker tested positive

Starting Sunday Kara began 8-14 days of isolation.

Her father says she’s had no symptoms, so far.

One additional alternate is considered a close contact, and is quarantining in her room until she tests negative. Leanne Wong said at Olympic trials that she had not been vaccinated. Kara, Kayla DiCello & Emma Malabuyo indicated they had been.

U.S. alternates have been training alongside the team, a poor decision. Obviously.

Oleg tested positive for meldonium

Oleg says he only once tested positive for the recently banned drug.

But was banned for 4 years.

He’ll appeal the ban.

Meldonium was added to the World Anti-Doping Agency (WADA) list of banned substances effective 1 January 2016 because of evidence of its use by athletes with the intention of enhancing performance. …

 A high prevalence of meldonium use by athletes in sport was demonstrated by the laboratory findings at the Baku 2015 European Games. 13 medallists or competition winners were taking meldonium at the time …

Meldonium use was detected in athletes competing in 15 of the 21 sports …

Most of the athletes taking meldonium withheld the information of their use from anti-doping authorities by not declaring it on their doping control forms as they should have. Only 23 of the 662 (3.5%) athletes tested declared the personal use of meldonium. However, 66 of the total 762 (8.7%) of athlete urine samples analysed during the Games and during pre-competition tested positive for meldonium. …

NCAA gymnasts – recurrent ACL injuries

An anterior cruciate ligament (ACL) rupture is a serious injury that can be career-ending in collegiate athletics.

A rerupture (recurrent rupture) after primary ACL reconstruction occurs in 1% to 11% of all athletes.

The highest rates of recurrent ACL ruptures (per 10,000 AEs) were among male football players (15), female gymnasts (8.2), and female soccer players (5.2). …

Of sports played by athletes of both sexes, women’s soccer had a significantly higher rate of recurrent ACL ruptures than men’s soccer (rate ratio, 3.8 [95% CI, 1.3-15]). …

ROC (Russian Olympic Committee)

Due to state-backed doping, approved by Putin (I assume), “Russia” will not be competing in Tokyo.

I am happy the athletes were not banned outright as, of course, many did not dope.

… a Court of Arbitration for Sport ruling from December which barred Russia’s name, flag, anthem and other national symbols in a package of sanctions over what it deemed Russia’s failure to turn over accurate data from the Moscow drug-testing laboratory.

The team in Tokyo will be officially known not as “Russia,” but as “ROC”, for Russian Olympic Committee. …

Australia Institute of Sport at 40

In the early 1990s I travelled to Canberra to research the AIS. We had nothing like it in Canada.

World H Bar Champ Philippe Rizzo was there 1995-2010.
