Australia’s Olympic swimmers are getting into the realm of digital actuality to maximise their performances on the Paris Video games in July. The relay crew have began utilizing digital actuality goggles as a brand new instrument to enhance their changeover instances by the fractions of a second that may determine gold and silver medals.
The Australian crew was on the rostrum in all seven swimming relay occasions on the Tokyo Video games, together with gold within the ladies’s 4x100m freestyle and medley relays, as a part of a document medal haul. However ambitions are even greater for Paris, after Australia received three gold medals, three silver and one bronze in the identical seven occasions ultimately yr’s world championships in Fukuoka.
Quick relay changeovers, within the vary of 0.1 to 0.2 of a second, could make a distinction of between half a second and a second to the whole time of the crew.
The Australian crew held a relay camp instantly after final month’s nationwide championships on the Gold Coast the place the swimmers have been launched to VR goggles which have been programmed with 3D video of their teammates swimming into the end of a relay leg. This permits them to observe how every swimmer finishes their leg and choose precisely when they need to depart the blocks to make a quick, however authorized changeover.
Groups are disqualified if the digital timing registers {that a} swimmer’s toes have left the blocks earlier than the earlier swimmer has touched the wall.
Swimming Australia’s basic supervisor for efficiency assist Jess Corones stated the crew assist employees have been exploring new expertise to optimise the pace of the changeovers.
“What we’re attempting to do is locate totally different inventive methods of getting relay athletes to have the ability to follow that changeover,” Corones stated. “You’ve obtained the bodily follow, clearly, however then there’s the anticipation of the swimmer coming into the wall. Typically once you’re on the nationwide crew, you’re not altering over with somebody in your [training] squad, in order that they have fairly restricted time to truly follow the changeovers.”
Corones stated the VR goggles allowed the swimmers to visualise changeovers extra successfully and follow extra repeatedly.
“The final couple of years main into Tokyo, we’d simply video [all the relay swimmers] and they’d have a normal video on their telephones, and so they may undergo and watch it,” she stated. “It helps them with their anticipation, ensuring they’ve obtained good consciousness and making them as comfy as they are often in that atmosphere to execute the talent at a very excessive degree. The VR goggles are taking that to a different degree the place we’re attempting to create an much more actual atmosphere.”
The crew’s sport scientists have spent the previous few months filming every potential relay swimmer from above the beginning blocks to seize the view {that a} swimmer standing on the beginning blocks has of the swimmer ending their leg of a relay. The movie is then uploaded to the goggles.
“The following part [post-Paris] will probably be seeing if we are able to convey their motion sample into that,” Corones stated. “In the intervening time it’s about visualisation and anticipating timing and the preparation that they want mentally for that. They will’t dive in [with the VR goggles] however we’d be capable to get them to do a standing leap so we may time their response.”

Australian head coach Rohan Taylor stated the flexibility to simulate changeovers extra successfully was a helpful improvement. He stated the coaches had additionally used “gamification” as a part of their bodily relay follow on the current coaching camp.
“What we’re attempting to do is put them beneath strain, and measure them on changeovers,” Taylor stated. “In between the relay legs, they’re having to do some type of gamified duties, like they need to shoot baskets. They obtained factors for nonetheless many baskets they made earlier than they obtained on the blocks. Then after they obtained on the blocks they needed to execute the changeover inside a time span to get most factors.”
The purpose is to show the swimmers to execute their expertise regardless of any exterior distractions, which is what they are going to face within the febrile atmosphere of the Olympic enviornment. Corones added that the final word purpose of efficiency evaluation was to present athletes and coaches speedy suggestions, in coaching and competitors.
Biomechanist Dr Bruce Mason pioneered race evaluation – measuring begins, turns and components of a race to supply suggestions to coaches and swimmers – on the Australian Institute of Sport within the Nineties. However the knowledge supply took some hours after every race, and was centered solely on the Australian swimmers.
By the Tokyo Olympics in 2021, the nationwide crew’s efficiency analysts may produce the identical knowledge for all eight swimmers in a race in simply over 20 minutes. And Corones stated they might be 10% quicker once more in Paris.
“For the coaches there will probably be a noticeable improve within the pace by which they get their knowledge,’’ she stated. In a sport which is set by hundredths of a second, that might make a distinction.
