What BET really is and how omitting it can leave you vulnerable
Brain Endurance Training is NEURAL CAPACITY TRAINING
Mental fatigue impacts our perception of effort which will in turn decrease our mental and physical capacity. The higher our perceived effort, the less access we have to our physical and mental reserves. No matter how well trained or elite we are. This therefore creates a detrimental knock on effect to performance. Additionally, it has also been shown that mental fatigue decreases prefrontal oxygenation which will also limit our capacity.
Brain Endurance Training (BET) can alter prefrontal oxygenation
Reductions in prefrontal oxygenation can limit human performance
Brain Endurance Training (BET) summed up in once sentence is, “neural capacity training” If you peel back all the layers the goal is always the same, overload the brain to create adaptation to increase your athletes physical and mental capacity, which in turn gives them the ability to perform at the highest level for longer.
Brain Endurance Training is neural CAPACITY TRAINING
The below studies show that mental fatigue can increase muscle tension, biomechnical strain and reduce ability to recover. In professional sports this can potentially cost clubs millions as mental fatigue can easily go undetected. This leaves expensive athletes more prone to injury and time off. If you are not tracking the appropriate data, and do not have a solution in place for mental fatigue, you are vulnerable to the downfalls and expenses that come with lower performance levels and injured athletes.
You could have the best physical prep in the world but if you are not looking at conditioning the brain appropriately, you are leaving a lot on the table.
Key points
- Mental fatigue may produce increased muscle tension and exacerbate task-related biomechanical strain. (Bonger et all, 1993)
- Mental fatigue may affect awareness and reporting of musculoskeletal symptoms (Sauter & Swansson, 1996)
- Mental fatigue impairs recovery after work (Melin & Lundberg, 1997)
- Similar brain regions activated during physical and mental fatigue manfestation (Dettmers et all , 1996)
- Mental fatigue can increase fatigability, enhance perception of effort and impair performance.

Effects of Mental Fatigue on the Development of Physical Fatigue: A Neuroergonomic Approach
Abstract
Objective:
The present study used a neuroergonomic approach to examine the interaction of mental and physical fatigue by assessing prefrontal cortex activation during submaximal fatiguing handgrip exercises.
Background:
Mental fatigue is known to influence muscle function and motor performance, but its contribution to the development of voluntary physical fatigue is not well understood.
Method:
A total of 12 participants performed separate physical (control) and physical and mental fatigue (concurrent) conditions at 30% of their maximal handgrip strength until exhaustion. Functional near infrared spectroscopy was employed to measure prefrontal cortex activation, whereas electromyography and joint steadiness were used simultaneously to quantify muscular effort.
Results:
Compared to the control condition, blood oxygenation in the bilateral prefrontal cortex was significantly lower during submaximal fatiguing contractions associated with mental fatigue at exhaustion, despite comparable muscular responses.
Conclusion:
The findings suggest that interference in the prefrontal cortex may influence motor output during tasks that require both physical and cognitive processing.
Muscle- and task-dependent responses to concurrent physical and mental workload during intermittent static work
Abstract
Many workers experience combined physical and mental demands in their jobs, yet the contribution of these demands to the development of musculoskeletal disorders is unclear. The purpose of this study was to investigate muscle- and task-dependent responses to concurrent demands during intermittent static work. Twenty-four participants performed shoulder, wrist, and torso exertions at three levels of physical workload (PWL) in the absence (control) and presence (concurrent) of a mental arithmetic task. Compared to the control, concurrent demand conditions resulted in decreased muscle activity (4–9% decrease), increased cardiovascular load (2–4% increase), and impaired motor co-ordination (9–24% increase in force fluctuation). Furthermore, these outcomes were more prominent at higher PWL levels and within postural (shoulder and torso) muscles. Mental task performance exhibited greater interference with the physical task at low and high PWL levels. Thus, it may be important to consider these muscle- and task-specific interactions of concurrent demands during job design to address worker health and performance issues.
