How To Manipulate Cognitive Load With Task Duration.

There are many ways to manipulate cognitive load in a cognitive training plan. We can alter the cognitive tasks intensity, placement, and apply specialized training modes. These are all viable solutions for load manipulation.  

In this article, we will focus on manipulating task durations to alter the volume of cognitive load placed on the athlete's brain.

Manipulating Cognitive Load With Task Duration.

Changing the duration of a cognitive task is going to alter the overall cognitive load on the athlete's brain. By extending the task duration even by a few minutes, the entire load of the session increases and the extra minutes add up over the course of the cognitive training plan. A few minutes more may not seem like very much, but when you add up what is happening over those minutes you will understand why increasing task duration can be so essential. The same works in reverse, taking a few minutes off each session is an effective deloading strategy as a handful of minutes off each session will significantly reduce the total reps and overall load on the athlete.

For example,

Performing 9 minutes of cognitive training per week over a month can total 1,620 cognitive reps per month. BUT performing an additional 6 minutes of cognitive training (15 minutes total) per week takes the monthly total to 2,700 cognitive reps. These small changes to task duration can have a huge influence on the total amount of REPS your athlete's brain clocks up. These reps are vital practise, repetition is how we train ourselves to be great at anything. Plus this significantly increases the cognitive load your athlete experiences.

Deloading

As you can see in the examples below the minimal effective dose starts at 45m per week of cognitive training. Research has shown that we make around 35,000 decisions per day, so if your athlete's cognitive reps are only 1200 reps per week the load is not sufficient enough to create any meaningful cognitive adaptations. That amount of load is childs play for the brain. This is not to say that these smaller loading schemes are useless, but they should be used as a de-load strategy rather than the cornerstone of the cognitive training plan. Begin with the minimal effective dose, and increase in increments knowing that the additional 6 minutes or so is going to have an effect. Keep your shorter sessions and fewer reps for deloading much in the same way you would in a running or weights program.

Example,

The below cognitive reps per minute are averaged at 45 to keep things simple.
