Dear Editor,

The recent article by Shah and Chauhan[1] highlighted many vital points regarding the impact of physical activity (PA) on cognitive performance among young adults. However, there is a need to emphasize the type and intensity of PA that is effective in improving cognition in young people. According to a recent study conducted by Nakagawa et al.,[2] they found that regular participation in moderate-to-vigorous-intensity PA attaining at least 3000 MET-min/week, rather than low-intensity PA, was associated with improvements in cognitive and mental health parameters among young adults. A single bout of 30-min mat-based Pilates, a mind–body exercise technique centered on core stability and muscle control, substantially decreased overall mood disturbance, anxiety, and fatigue among young male adults.[3]

The physiological mechanisms behind exercise mediated improvements in cognitive functioning among younger adults could be associated with exercise-induced rises in circulating levels of brain-derived neurotrophic factor, a growth factor that increases neural plasticity and synaptic growth and transmission and has been proven to improve cognition due to its upregulation and role in angiogenesis.[4] An additional mechanism is an exercise-induced rise in cerebral blood flow (CBF), and rises in CBF are related to increased executive functioning.[4]

In conclusion, there is a need to promote PA among young adults in order to improve their cognitive performance and to inculcate the habit of regular PA among them so as to encourage healthy living throughout their lifetime because the effect of aerobic exercise on cognition is more distinct as age increases, signifying that regular participation in aerobic training could lessen age-associated cognitive declines.[5],[6] However, future studies should investigate the exact dose of moderate-to-vigorous-intensity PA that is effective in mitigating age-related cognitive declines.
