In 2023, a review by Luis Ciria challenged the previously established consensus on the positive effects of exercise on cognitive functions. Earlier studies, including a prominent 2020 meta-analysis, strongly supported the claim that physical activity benefits cognitive processes across all age groups. However, Ciria's review, which analyzed 24 meta-analyses, indicated that there was insufficient evidence to conclusively assert that exercise directly influences cognition. This revelation sparked significant controversy and debate, with researchers arguing over the criteria used in prior studies. The discussion highlights a pivotal moment in our understanding of the sport-cognition relationship.
"Even the World Health Organization echoed this robust cause-effect relationship between exercise and cognitive benefits, highlighting the widespread belief in this dynamic prior to 2023."
"Ciria and his team’s review concluded that the evidence supporting exercise’s effect on cognition was not solid, leading to a reevaluation of earlier consensus."
