Drinking beetroot juice before exercising boosts brain performance

Islamabad, Apr 20: New research has found that it may be possible to bolster these effects, simply by drinking beetroot juice before exercising.

The research team – including co-author W. Jack Rejeski of the Department of Health and Exercise Science at Wake Forest University in Winston-Salem, NC – says that the increased brain connectivity seen among the adults who drank beetroot juice was comparable to the connectivity seen in younger adults. Beetroot – often referred to as “beet” – is a root vegetable best known for dominating plates of food with its bright purple juice. In recent years, beetroot has gained popularity for its potential health benefits, which include reduced blood pressure and increased exercise performance.
Studies have demonstrated that exercise alone can benefit the brain. For their study, Rejeski and team set out to investigate whether beetroot juice might boost the brain benefits of physical activity.
The team found that subjects who consumed the beetroot juice supplement prior to exercising demonstrated a structurally stronger somatomotor cortex – a brain region that helps to control body movement – compared with participants who consumed the placebo.
Furthermore, subjects who drank the beetroot juice supplement also showed greater connectivity between the somatomotor cortex and the insular cortex, a brain region associated with motor control, cognitive functioning, emotion, and other brain functions. Such connectivity is usually seen in the brains of younger individuals, the team notes.
The researchers explain that the somatomotor cortex receives and processes signals from the muscles. As such, physical activity should strengthen this process.
They suggest that beetroot juice strengthens the somatomotor cortex further through its nitrate content; its conversion into nitric oxide boosts the delivery of oxygen to the brain.
