A new study currently finds that the relationship between physical and brain fitness varies in older adults by virtue of their sex. The study was published ahead of print in the Journal of Applied Physiology on the weekday. Cardio-respiratory fitness is that the measure of how much, and how well, oxygen is delivered to the muscles during exercise. Furthermore, the fitness level is additionally related to changes within the brain’s nerve-tissue, referred to as nerve tissue, and higher psychological feature operates in later life.

Earlier, studies have found cardio-respiratory fitness to be associated with how the brain functions during times of rest. Nerve connectivity within the brain throughout rest changes with age. The studies found that these changes will negatively have an effect on psychological feature operate. However, “the neural basis of sex variations within the relationship between fitness and cerebrum function in older adults has not been directly explored,” wrote researchers from York University and McGill University in Canada.

The study found researchers learning one cluster of men and one among the women, both with an average age of sixty seven. The volunteers self-reported their typical daily physical activity level. The analysis team recorded the participants’ height, weight, age, sex and resting pulse to work out their cardio-respiratory fitness.

They additionally administered imaging tests of the brain to record nerve function both inside specific brain networks (local efficiency) and among all networks (global efficiency). The study found men to be having higher cardio-respiratory fitness levels than women. However, the women had higher local network potency and lower international network potency than the men.

This pattern of connectivity was more robust in the women and has been positively associated with executive functions, which are skills that contribute to being able to focus, pay attention and manage time.

Fitness levels, however, were more strongly associated with improving this brain efficiency pattern for men than women. The researchers wrote, “Our findings that (cardiorespiratory fitness) is related to brain operate in a very sex-dependent manner underscore the importance of considering sex as an element once learning associations between exercise and brain health in older adulthood.”
