This research adds to the growing evidence that engaging in physical activity, even if limited to weekends, can provide significant health benefits similar to those of regular exercise routines.

It's important to note that the study is observational, meaning it cannot definitively establish causation, and it has limitations such as potential non-representativeness of respondents and reliance on self-reported data.

The study emphasizes that the timing of exercise is less crucial than the act of exercising itself, highlighting that even minimal physical activity can positively influence cognitive health.

Moreover, mild exercise has been shown to reduce the risk of over 200 diseases, underscoring its importance for overall health.

Chris Russell from the University of Worcester has called for further research on dementia, particularly in middle- to low-income countries, stressing the role of diverse physical activities in preventing cognitive decline.

The findings of this study could have significant implications for public health policies, especially for busy individuals in Latin America and beyond, suggesting that weekend warrior workouts are a feasible option.

Cognitive function was assessed using the Mini Mental State Examination, a widely recognized tool for screening cognitive impairment and dementia.

Dr. Gary O'Donovan noted that even busy individuals can reap benefits from exercising just once or twice a week, similar to those who maintain more frequent workout schedules.

A recent study reveals that individuals who exercise only on weekends, dubbed 'weekend warriors,' are 13% less likely to develop mild cognitive impairment compared to those who do not exercise, while regularly active individuals enjoy a 12% lower risk.

However, to effectively reduce disease risk, weekend warriors must ensure their exercise sessions are sufficiently long to meet recommended activity levels.

The research team, which included academics from Latin America and Europe, analyzed data from over 10,000 middle-aged participants in Mexico City, monitored for an average of 16 years to assess cognitive decline.

Possible mechanisms for the protective effects of exercise on brain health include increased brain-derived neurotrophic factor and enhanced brain plasticity, which contribute to improved cognitive function.
