An Australian researcher says the extreme precision and reaction speed of Olympic divers and gymnasts can be attributed to unique visual training and skills which allow them to see and process information at blinding speeds.
When University of Melbourne senior lecturer Christine Nearchou watches elite athletes perform, much of her attention is focused on their eyes.
"I'm watching just how well they're using their visual system to then drive what they physically can do. In particular with gymnastics, just watching their visual system, how focused they are, you can see it in their face, you can see that their vision is laser sharp and they've already planned out what they're going to do," she said.
Nearchou, who works in optometry and vision sciences, says the visual skills found in Olympic divers and gymnasts are very different from what most of us possess.
"Studies show that they are able to manipulate their visual system and their natural reflexes so that they can bring their eyes and their eye movements to where they need to be. For example, we have a reflex or a primitive reflex that we're born with called the vestibular ocular reflex or gaze stabilization," Nearchou said.
For elite divers and gymnasts, this stabilization can get in the way, and part of their training involves learning how to shut it off. Another critical skill athletes rely on is visualization -- seeing exactly what they are about to do in incredible detail.
"So, they're gaining more information, they're analyzing, interpreting, learning from what they've seen and being able to compartmentalize that and then instruct the motor skills what to do. And they're doing that with not only perfect accuracy, but with perfect timing. And that's where mortals like us are in awe – when I say that they can seamlessly integrate those two systems," Nearchou said.
Nearchou said possessing highly tuned visual processing skills is critical to avoiding mistakes and serious injuries. She said these athletes are relying on those skills as they fly and twist through the air.
"So, that makes it even more unbelievable and incredible and puts us in awe. Even as a vision scientist, I'm still in awe of what they can achieve, having superiorly developed that visual cognition side of their brain," she said.

A Chinese UN representative said the tension in the Red Sea is a prominent manifestation of the spillover of the Gaza conflict at a Security Council briefing on Yemen on Thursday.
Geng Shuang, China's deputy permanent representative to the United Nations, made the remarks while also calling on the Houthis to respect the right of commercial vessels of all countries to navigate in the waters of the Red Sea in accordance with international law.
"he tension in the Red Sea is a prominent manifestation of the spillover of the Gaza conflict. It has been 11 months since the outbreak of the Gaza conflict and there is still no peace in sight. The negative effects of the conflict are increasing instability in the region. China once again urges the full implementation of the relevant Security Council resolutions and an immediate and lasting ceasefire in Gaza," said Geng.
The representative said China has always maintained that resolving the Yemen issue must rely on political and diplomatic means. He added that relevant parties should jointly advance a comprehensive political process that is "led by and owned by the people" and resolve differences through dialogue and negotiation.
China looks forward to countries with influence on Yemen playing a constructive role and calls on the Yemeni government and the Houthis to work together to implement the agreements reached between the two sides on financial and aviation issues, Geng said.
A Greek-flagged oil tanker named "MV Sounion", carrying about 1 million barrels of crude oil, was attacked by Houthi forces on Aug. 21 with small arms, projectiles, and a drone boat. The situation escalated when Houthi forces released footage on Aug. 29 showing them boarding and placing explosives on the oil tanker, setting off blasts that put the Red Sea at risk of a major oil spill.
Geng expressed concern over the attack on the oil tanker, the possible oil spill, and the potential ecological and environmental impact.
He also pointed out that many provinces in Yemen are suffering from severe floods and the humanitarian situation has worsened. The international community should step up humanitarian assistance to Yemen, he said.
The deputy permanent representative also expressed grave concern over the detention of UN personnel in Yemen and called for the immediate and unconditional release of all UN personnel.
