{{Short description|Condition of sudden skill or control loss in an athlete}}
In [[sports]], the '''yips''' are a sudden and unexplained loss of ability to execute certain skills in experienced athletes. Symptoms of the yips are losing [[Motor coordination|fine motor skills]] and [[psychology|psychological]] issues that impact the [[muscle memory]] and decision-making of athletes, leaving them unable to perform basic skills of their sport.
The exact cause of the yips is still not fully understood. A yips episode may last a short time before the athlete regains their abilities or it can require longer term adjustments to technique before recovery occurs. The worst cases are those where the athlete does not recover at all, forcing the player to abandon the sport at the highest level.
There have been a plethora of treatment options tested to ameliorate the yips, including clinical [[sport psychology]] therapy, motor imagery, pre-performance routines, medication, botulinum toxin, acupuncture, and emotional freedom techniques. However, their possible effectiveness is primarily based on personal experience rather than well-founded research evidence.{{cn|date=May 2024}} Early intervention with a thorough treatment plan is imperative for recovery of athletes with yips.<ref>{{Cite journal |last1=Lenka |first1=Abhishek |last2=Jankovic |first2=Joseph |date=2021-12-21 |title=Sports-Related Dystonia |journal=Tremor and Other Hyperkinetic Movements |volume=11 |issue=1 |pages=54 |doi=10.5334/tohm.670 |doi-access=free |issn=2160-8288 |pmc=8698216 |pmid=35036047}}</ref>
== Brain activity and the yips ==
Although the exact cause of the yips has yet to be determined, one possibility is that, in some golfers, the condition may result from biochemical changes in the brain that accompanies aging. Excessive use of the involved muscles and intense demands of coordination and concentration may make the problem worse. [[Focal dystonia]] is mentioned as another possibility for the real cause of yips.▼
A specific 2021 study using EEG recordings to measure found that athletes with the yips showed increased brain activity in the alpha band when initiating movements, especially when increasing force output to match a target.<ref>{{Cite journal |last1=Watanabe |first1=Tatsunori |last2=Yoshioka |first2=Kiyoshi |last3=Matsushita |first3=Kojiro |last4=Ishihara |first4=Shin |date=2021-05-14 |title=Modulation of sensorimotor cortical oscillations in athletes with yips |journal=Scientific Reports |language=en |volume=11 |issue=1 |page=10376 |doi=10.1038/s41598-021-89947-1 |issn=2045-2322 |pmc=8121935 |pmid=33990687|bibcode=2021NatSR..1110376W }}</ref> In this particular study, increased brain activity in the alpha and beta bands for the treatment group after the movement compared to the control group, suggested that heightened brain activity might indicate problems with inhibitory systems or increased focus on the body part involved in the task. Further research must be conducted with a larger sample size, more diverse populations, and more than two EEG electrodes in order to further establish the validity of this claim.
==In golf==
In [[golf]], the yips is a movement disorder known to interfere with putting. The term ''yips'' is said to have been popularized by [[Tommy Armour]]—a golf champion and later golf teacher—to explain the difficulties that led him to abandon tournament play.<ref>Barkow, A. and Barrett, D. (1997) ''Golf Legends of All Time''. Publications International.</ref> In describing the yips, golfers have used terms such as ''twitches'', ''staggers'', ''jitters'' and ''jerks''. The yips affects between a quarter and a half of all mature golfers.<ref>Smith et al., 2000.</ref> Researchers at the [[Mayo Clinic]] found that 33% to 48% of all serious golfers have experienced the yips.<ref>{{Cite web|date=2004-07-18|title=Beware of the yipsDreaded golf affliction has no known cure|url=https://oklahoman.com/article/2859396/beware-of-the-yipsbrdreaded-golf-affliction-has-no-known-cure/|access-date=2021-01-31|website=Oklahoman.com}}</ref> Golfers who have played for more than 25 years appear most prone to the condition.<ref>{{Cite web|last=Letter|first=Courtesy of Mayo Clinic Health|title=Yips: More than a putting problem|url=https://tulsaworld.com/archive/yips-more-than-a-putting-problem/article_d29f1e4a-08f5-5c6d-adcb-2b13a94d4892.html|access-date=2021-01-31|website=Tulsa World|date=16 October 2002 }}</ref>

Professional golfers seriously afflicted by the yips include [[Ernie Els]], [[David Duval]], [[Pádraig Harrington]], [[Bernhard Langer]], [[Ben Hogan]], [[Harry Vardon]], [[Sam Snead]], [[Ian Baker-Finch]] and [[Keegan Bradley]], who missed a four-foot putt in the final round of the 2013 [[HP Byron Nelson Championship]] due to the condition (although he may also have been suffering from [[strabismus]]).{{citation needed|date=October 2018}} At the 2015 Waste Management Open, golf analyst [[Nick Faldo]] suggested that [[Tiger Woods]] could be suffering from the yips. Jay Yarow from ''[[Business Insider]]'' commented after the 2014 Open that Woods had both the putting yips and the driver yips.<ref>{{Cite news|url=http://www.businessinsider.com/tiger-woods-era-over-2014-7|title=The Tiger Woods Era Is Over|last=Yarow|first=Jay|date=2014-07-21|work=Business Insider|access-date=2018-04-06}}</ref>
Interventions seeking to treat the affliction have been few and far between. Some golfers have tried changing their putter or their grip or even switching hands. However, these strategies have provided only temporary relief.{{citation needed|date=November 2017}}

==In tennis==
In [[tennis]], the yips most often affects the (second) [[Serve (tennis)|serve]], leading to multiple [[Double fault (tennis)|double faults]]. Several top players have been affected by the yips in recent years, most notably [[Alexander Zverev]] in 2019,<ref>{{cite web | url=https://tennishead.net/alexander-zverev-holds-massive-unwanted-lead-on-atp-list-that-includes-djokovic-nadal/ | title=Alexander Zverev holds massive unwanted lead on ATP list that includes Djokovic & Nadal | date=5 September 2019 }}</ref> and [[Aryna Sabalenka]] in the beginning of 2022.<ref>{{cite web | url=https://www.tennismajors.com/stats-that-mattered-in-2022/the-statistics-that-defined-2022-sabalenka-plagued-by-428-double-faults-but-perseveres-648581.html | title=The statistics that defined 2022 - Sabalenka plagued by 428 double-faults but laughs it off and perseveres | date=23 December 2022 }}</ref> For example, Zverev served a record of 20 double faults in his [[2019 Western & Southern Open|2019 Cincinnati Masters]] first round loss against [[Miomir Kecmanović]], while Sabalenka served up 39 double faults in her two first round losses in the 2022 [[2022 Adelaide International 1|Adelaide 1]] and [[2022 Adelaide International 2|Adelaide 2]] tournaments. From 2005-2008, [[Guillermo Coria]], a former world no.3, suffered from service yips.

==In baseball==
In baseball, the yips usually manifests itself as a sudden inability to throw the baseball accurately.<ref name=yips>{{cite web |url=https://www.mlb.com/news/players-who-had-the-yips |title=Players Who Had the Yips |last=Kelly |first=Matt |website=[[MLB.com]] |date=October 14, 2020 |access-date=July 14, 2021}}</ref> They are more apparent in [[pitcher]]s and [[catcher]]s, players who touch the ball the most in the game, though position players have also been subject to the malady.
[[Pittsburgh Pirates]] pitcher [[Steve Blass]] is an example; from 1964 to 1972, he was a dominant pitcher and All-Star; however, beginning in 1973, he suddenly lost his command, issuing 84 [[base on balls|walk]]s in {{frac|88|2|3}} [[innings pitched]].<ref>{{cite web |url=https://www.retrosheet.org/boxesetc/1973/Lblass1010091973.htm |title=The 1973 PIT N Pitching Splits for Steve Blass |website=[[Retrosheet]] |date=August 23, 1989 |access-date=November 17, 2018}}</ref> He retired in 1974 due to continued loss of his pitching ability.
"Steve Blass disease" has been attributed to talented players—such as [[New York Yankees]] [[second baseman]] [[Chuck Knoblauch]] or [[Los Angeles Dodgers]] second baseman [[Steve Sax]]—who suddenly lost their ability to throw the ball accurately to the [[first baseman]]. Sax's problems began in his 3rd season in the [[Major League Baseball|majors]], but he continued to play in the league and seemingly recovered by 1989, going on to finish his career in 1994.<ref>{{Cite web|url=http://m.mlb.com/news/article/47124896/the-yips-difficult-to-understand-difficult-to-cure/|title=The Yips: Difficult to understand, difficult to cure|last=Meisel|first=Zack|date=2013-05-10|website=MLB.com|access-date=2018-04-06}}</ref>

For the rest of his career, when required to field a hit ball, Lester would run most of the way to 1st base and underhand throw the ball and on longer throws would spike it into the turf to reduce the chances of throwing it past the bag. His team also attempted to compensate for the problem with their catchers throwing 'back picks' to first base as well as the regulation throws to second.

==In gymnastics==
In [[artistic gymnastics]], the yips are known as the "twisties". They refer to a sudden loss of a gymnast's ability to maintain body control during aerial maneuvers. Some gymnasts reference a feeling of disorientation or unawareness of where the ground is. This loss of air awareness increases the chance of a serious or critical injury occurring if the gymnast forgets in the moment how to land the maneuver safely. During the 2020 Olympic qualifications, American gymnast [[Simone Biles]] flew out of bounds twice on the floor and failed to stick her landing on the vault. Despite this, she still qualified for the all-around final in first place. During the Olympic events, Biles was unable to complete her skills and popularized the term "twisties," causing her to withdraw from competition after the [[Gymnastics at the 2020 Summer Olympics – Women's artistic team all-around|women's team all-around]] final. She attributed her loss of air awareness to a mental health condition. Biles returned to perform a downscaled routine in the [[Gymnastics at the 2020 Summer Olympics – Women's balance beam|balance beam]] final, winning the bronze medal.<ref>{{Cite web|last=Reeve|first=Elle|date=July 28, 2021|title=Simone Biles and 'the twisties': How fear affects the mental health and physical safety of gymnasts|url=https://www.cnn.com/2021/07/28/us/simone-biles-olympics-gymnastics-physical-mental-health/index.html|access-date=2021-07-28|work=CNN}}</ref><ref>{{cite news|url=https://www.washingtonpost.com/sports/olympics/2021/07/28/twisties-gymnastics-simone-biles-tokyo-olympics/|title=Simone Biles said she got the 'twisties.'
