Older people who indulge in physical activity should increase their amount of water intake, to reap the full cognitive benefits of exercise, researchers suggest.
Dehydration has been shown to impair exercise performance and brain function in young people, but less is known about its impact on older populations.
The findings showed that hydration boosts performance on test of executive function that includes the skills needed to plan, focus, remember and multitask following exercise. Exercise has been shown to improve intellectual health, including executive function.
“Middle-age and older adults often display a blunted thirst perception, which places them at risk for dehydration and subsequently may reduce the cognitive health-related benefits of exercise,” said researchers including Brandon Yates, of Spaulding Rehabilitation Hospital in Boston, US.
The study, presented at the American Physiological Society (APS) annual meeting at Experimental Biology 2018 in San Diego, explored the association between hydration status before exercising and exercise-enhanced cognition in older adults. The team recruited recreational cyclists (average age 55) who participated in a large cycling event on a warm day (78-86 degrees F).

The cyclists performed a “trail-making” executive function test–quickly and accurately connecting numbered dots using paper and pencil — before and after the event.
The team tested the volunteers’ urine before they exercised and divided them into two groups — normal hydration and dehydrated — based on their hydration status.
The normal hydration group showed noticeable improvement in the completion time of the trail-making test after cycling when compared to their pre-cycling test. The dehydration group also completed their post-cycling test more quickly, but the time reduction was not significant.
“This suggests that older adults should adopt adequate drinking behaviours to reduce cognitive fatigue and potentially enhance the cognitive benefits of regular exercise participation,” the researchers said. IANS
In a video posted on YouTube, the robot called 'Ameca' displays various human expressions, like appearing to "wake up" from sleep, as its face shows confusion and frustration when it opens its eyes.

Once awake, 'Ameca' starts looking at its hands and arms, opens its mouth and raises its eyebrows, just like a human does.
At the end of the video, Ameca smiles and holds a welcoming hand out towards the viewer.
According to Engineered Arts, the humanoid bot is currently unable to walk and it is working towards giving it the ability in the near future.
"Designed specifically as a platform for development into future robotics technologies, 'Ameca' is the perfect humanoid robot platform for human-robot interaction," says the company.
The 'Ameca' hardware is a development based on its own research into humanoid robotics and built on its advanced 'Mesmer' technology.

MediaTek's plans to boost technology democratisation and enable access to disruptive connectivity with its range of mainstream to flagship 5G chips.
"We at MediaTek are focused on making 2022 a year aimed at rapid growth, business success, and substantial expansion in our R&D capabilities. For 2022, we are focused on further strengthening our presence in India, offering incredible experiences to customers, and supporting the country's technology initiatives with our expertise and collaboration with leading OEMs," Anku Jain, Managing Director, MediaTek India said in a statement.
In the flagship segment, MediaTek recently announced the Dimensity 9000 chip, which is a milestone of innovation and a rise to the incredible, built-to-power flagship 5G smartphones in the world, the company claims.
MediaTek Dimensity 9000 features a single Cortex-X2 performance core clocked at 3.05GHz, three Cortex-A710 cores at 2.85GHz and four Cortex-A510 efficiency cores at 1.8GHz.
It packs a 10-core Arm Mali-G710 that takes care of graphics processing, the report said.
The chipset also comes packed with MediaTek's fifth-generation APU with six total cores for AI processing.
The chipset can handle screens with up to a 180Hz refresh rate at Full HD+ resolutions. It is also the first chipset to have an 18-bit image signal processor, offering the ability to capture 4K HDR video using up to three cameras at the same time, or still photos using up to a massive 320MP sensor.
