More intensive activity is not always better for a person’s memory

Intense exercise isn’t always better! More rigorous trainers have a harder time recalling specific events than those who do more moderate exercise, study finds
- People who exercise more intensively may not always score better on memory tests despite existing medical literature, a new study finds
- A study found that those who take part in more rigorous exercise have better spatial memory but worse episodic memory than those who lightly workout
- Any sort of exercise is found to be better for a person’s brain than living a sedentary lifestyle, though
- People who reported suffering from depression or anxiety also scored better on some memory tests than others in the population

More intensive exercise is not always better for a person’s memory than moderate training, a new study finds.
Researchers from Dartmouth University in Hanover, New Hampshire, found that people who perform moderate regular activity often had better ‘episodic’ memory than their more rigorously exercising peers. This means that they remember specific events better.
Performing more intense exercise regularly does boost a person’s spatial memory, though, which allows them to remember locations better. This would, for example, make them more likely to remember where they parked their car.
The findings were surprising to experts, who noted that more intensive exercise is generally believed to be correlated with stronger memory and overall brain function. This study highlights that different levels of activity may impact different parts of the brain – and have differing impacts as a result.

‘Mental health and memory are central to nearly everything we do in our everyday lives,’ Dr Jeremy Manning, an assistant professor of psychological and brain sciences at Dartmouth, said in a statement.
‘Our study is trying to build a foundation for understanding how different intensities of physical exercise affect different aspects of mental and cognitive health.’
Researchers, who published their findings last week in Scientific Reports, gathered data from 113 FitBit users for the study.
Each shared their fitness data – as tracked by the device – from the past year with researchers, performed memory tests and answered surveys about their mental health.

Judging by previous research, the Dartmouth team expected that the more intensive exercise group to perform better in all types of memory than their peers, but this was not the case.
People whose primary exercise over the past year was described as ‘moderate’ performed better than their peers who took part in more excessive training on episodic memory tests.
Researchers describe episodic memory as the ability to remember autobiographical events, like explaining what a person did the day before.
Those who took part in more intensive workouts performed better on spatial memory, which is a person’s ability to remember the locations of things.
There was no significant difference found in scores on associative memory examinations.
Any exercise is better than no exercise, though, with active participants testing better on overall memory that their more sedentary counterparts.
Researchers also found that people suffering from anxiety or depression perform better on spatial and associative memory tasks than others do.
‘When it comes to physical activity, memory, and mental health, there’s a really complicated dynamic at play that cannot be summarized in single sentences like ‘walking improves your memory’ or ‘stress hurts your memory,’ Manning explained.
‘Instead, specific forms of physical activity and specific aspects of mental health seem to affect each aspect of memory differently.’
This is not the only recent study to find potential benefits in moderate exercise over more intensive work-outs when it comes to cognitive health.
A study published last week by researchers at the University of Pittsburgh Medical Center found that moderate exercise throughout the day was more valuable that short bursts of intensive physical activity for elderly people looking to keep their brain in shape.
