The Strong Link: Strength And The Brain

How Strength Training Supercharges Memory and Mental Clarity

Are you looking to enhance your focus and mental clarity? 

Strength training might be the missing link you’ve been searching for. 

In this article, we will explore how strength training can supercharge your cognitive abilities and help you reach new levels of concentration and mental sharpness.

Strength training, BDNF and brain function

In terms of the clinical evidence, it’s BDNF that is the key mechanism behind the positive impacts on memory and learning that are associated with strength training.

By increasing brain-derived neurotrophic factor (BDNF), a protein that plays a crucial role in the growth, maintenance, and survival of neurons in the brain, strength training can boost the brain’s ability to adapt, reorganise, and form new neural connections. 

This increased neuroplasticity is directly linked to improved memory, enhanced information processing, and better focus and concentration.

How does strength training affect the brain?

The benefits of strength training for focus and mental clarity are numerous and well-documented. As we delve deeper into the science behind this connection, it becomes clear that incorporating strength-based exercises into our routine can have a transformative effect on our cognitive abilities.

Here are just some of the ways strength training impacts the brain:

1. Improves mood and cognitive function

Not only does it increase your overall physical strength, but it also helps improve brain function and mood by boosting dopamine and serotonin. 

Strength training also releases endorphins which can support mental clarity and cognitive function long after your workout has finished. 

2. Stimulates BDNF to create new neurons

Research shows that strength training stimulates the production of brain-derived neurotrophic factor (BDNF), a protein that plays a vital role in promoting the growth of new neurons and synaptic connections in the brain.

By boosting BDNF levels through strength training, you can enhance neuroplasticity, the brain’s ability to reorganise and adapt. 

3. Improves memory and mental clarity

This increase in neuroplasticity can boost memory and mental clarity. Without getting too sciencey, BDNF is part of the cellular mechanism that promotes synaptic consolidation (a.k.a, it impacts the way the brain stores and files information in order to register it to memory).

Since strength training increases the rate at which BDNF is produced it’s thought to lead to improved memory, better problem-solving skills, and faster processing speeds. In short, the brain becomes more switched on.

Whatsmore, deregulation or lack of BDNF can have the opposite effect, causing memory and cognitive defects such as those associated with Alzeihmers. So as we age it could be even more vital to utilise the benefits of strength training to our advantage.

Astonishingly, just 6 months of strength training has been proven to protect brain areas that are vulnerable to Alzeihmers disease for up to a year later.

4. Improves attention and focus

The act of lifting weights, maintaining proper form, and concentrating on the task at hand requires a high level of focus and mental engagement. This mental focus, when practised regularly, can translate to other areas of life, allowing individuals to better concentrate on their work, studies, or any other task that demands their attention.

Furthermore, strength training has been shown to have a positive impact on mood and stress levels. 

Scientific evidence – strength training and the brain

The connection between strength training and mental clarity is supported by a growing body of scientific evidence. 

Journal of Aging Research – 12 week study

One study published in the Journal of Aging Research examined the effects of a 12-week strength training program on cognitive function in older adults. The researchers found that the participants who engaged in regular strength training showed significant improvements in executive function, processing speed, and memory, compared to a control group. This suggests that strength training can be a powerful tool for maintaining and even enhancing cognitive abilities as we age.

Journal of the American Geriatrics Society

The researchers found that individuals who participated in regular strength training exercises had larger hippocampi, the brain region responsible for memory and learning. This increase in hippocampal volume was directly linked to improved cognitive performance, further reinforcing the cognitive benefits of strength training.

Scandinavian Journal of Medicine & Science in Sports 

The analysis, which included data from over 2,000 participants, concluded that strength training had a significant positive impact on various cognitive domains, including executive function, processing speed, and memory. 

Learn how to use strength training to your advantage

Strength training isn’t just amazing for the physical benefits. The strong link between strength training and mental clarity is undeniable. 

By engaging in regular strength-based exercises, you can unlock a host of cognitive benefits that can profoundly impact your focus, concentration, and overall mental acuity.

Through the release of brain-derived neurotrophic factor (BDNF) and the regulation of stress and anxiety, strength training can enhance neuroplasticity, improve memory and information processing, and support a more centred and focused mindset. The scientific evidence is clear – strength training is a powerful tool for improving brain health and cognitive function.
