A 101 Guide to Binaural Beats

Binaural beats are a form of brainwave entrainment that have been shown to have positive effects on stress, anxiety (1,2), focus (3), motivation, confidence and meditation (4). Binaural beats work when two different frequencies are heard, one in each ear. This creates a third tone, the binaural beat, whose frequency is the difference between the two other tones, e.g. if the tone in one ear is 400Hz and the other is 410Hz, the binaural beat is 10Hz. This binaural beat is shown to have a positive impact on the user’s mindset. It is important to note that stereo headphones are required to achieve a binaural beat since when using a speaker or non-stereo headphones the frequencies are already mixed outside the brain and hence no binaural beat is created.

The various tones of binaural beats affect the user differently. The following tones are used in the Rewire Mindset Recovery System:

  • 0.5 – 3.5 Hz – Delta wave for deep sleep
    • In a 2018 study, participants who received this frequency during sleep entered deep sleep quicker and for longer (5). This allows participants to gain more of the benefits of deep sleep including physical recovery.
  • 4.0 – 6.5 Hz – Theta for meditation/sleep
    • A 2017 study showed that even listening to a 6Hz binaural beat for just 10 minutes induced the user’s brain into a state similar to that achieved during meditation (4).
  • 7.0 – 12.5 Hz – Alpha for relaxation/dreams
    • In a 1990 study, alpha wave binaural beats were shown to have a positive influence on the user’s relaxation (6).
  • 13.0 – 38.5 – Beta for Activity            
    • It has been shown that beta wave binaural beats can positively affect vigilance performance and mood (3), and a recent 2019 study showed that beta wave binaural beats have a positive impact on long term memory (7).

Binaural beats also have a positive effect in counteracting the negative effects of mental fatigue. A recent 2020 study by Walter Staiano, Rewire’s Scientific Advisor, showed that binaural beats reduce the negative effect of mental fatigue (8). This makes binaural beats an important part of mindset recovery and pre-competition preparation in sports to minimise the negative effects that mental fatigue is shown to have on endurance performance (9,10).

We have put together a demo of our mindset recovery system featuring theta wave binaural beats which you can watch and download below.

An Athlete’s Guide to Looking After Yourself During​ the COVID-19 Crisis

Across the globe, people are limited, like never before, with what they can and can’t do. This has, naturally, had a massive impact on everyone’s life and health, meaning that it is more essential than ever to make sure that we tick all the boxes in terms of our health.

Exercise

During this time, it is incredibly important to keep exercising. Since (almost) all sporting competitions and events across the globe have been cancelled, it can become very demotivating to work without a goal. On top of this, with gyms closed and social distancing measures meaning that we cannot train with a partner, more barriers are in the way of our goals. The ability to overcome obstacles is what separates us as athletes.

“Obstacles don’t have to stop you. If you run into a wall, don’t turn around and give up. Figure out how to climb it, go through it, or work around it.”

Michael Jordan

At the very minimum, we want to maintain our fitness, however by using this unprecedented time to do more than anyone else, it distinguishes you and you will be ahead of the rest when we are released back into the sporting world again. One crucial thing to note is that it is important to do something even if it is significantly less than before. One study into resistance training showed that even when doing 1/9th of the original training, participants were able to maintain their muscle mass for the duration of a 32 week period, whereas those who did not undergo any training over 32 weeks regressed to their original muscle mass before the training plan began (1). However, now is not the time for complacency or downheartedness – we have a unique opportunity to use this time to progress and focus on our health in a way that we have never before.

It is also important to consider the positive effect that exercise has on our mental health. Exercise has been shown to reduce depression and anxiety and has positive effects on mood, self-esteem and cognitive function (2). This is another of the many reasons why we should continue to exercise regularly.

Sleep

With significantly reduced social commitments it is very easy to let our sleep habits go to pot. Aside from having a negative effect on our physical and mental recovery, poor sleep quality impairs our immune system (3), something we naturally don’t want during a global pandemic. When sleeping, there are a few crucial things to take into account: consistency, appropriate length and quality – all which influence each other. By setting a consistent bedtime and wake up time you can reduce the time it takes to fall asleep as well as improving the quality of your sleep by allowing you to spend appropriate time in each sleep stage. When considering sleep length it is important to remember not only to get enough sleep but also not to get too much, having too little or too much sleep is associated with worse health (4). We cannot ‘store’ sleep and so once we have achieved all the sleep we need, sleep is essentially a waste of time and time that we can utilise for better purposes. When considering appropriate sleep length it can also be helpful to think in terms of 90-minute cycles, rather than hours – a more accurate representation of our sleep. You can use an app such as SleepCycle to track your sleep and wake you up at the lightest point so you feel free and ready to start the day. It is crucial to practice good sleep habits, try to turn off blue light sources as you prepare to sleep so as not to interfere with melatonin secretion, which is inhibited by the presence of blue light.

Nutrition

Strictly speaking, the immune system cannot be boosted through vitamins. However, vitamins can be used to support normal immune function. Whilst it might not be necessary to supplement vitamins or minerals, it is important to get a sufficient amount in your diet, and if you are unable to achieve suitable levels with your diet, then consider changing your diet or supplementing. Essential vitamins and minerals for supporting immune function are copper, folate, iron, selenium, zinc and vitamins A, B6, B12, C and D (5). You might find it useful to use an app, such as Cronometer, to track your micronutrient intake and highlight deficiencies. One vitamin to highlight in particular is vitamin D, which we get from sunlight. Considering the lockdown measures that many countries have put in this creates a challenge, particularly knowing that in normal circumstances 40% of Americans are deficient in vitamin D (6). If you have a garden, try to use it throughout the day or if your current government regulations allow, try to get outside, whilst abiding by social distancing measures. If you are unable to get outside, then consider supplementing vitamin D. Overall maintaining a healthy diet, rich in the relevant nutrients can help to maintain immune function during this crucial time.

Mindfulness

During this strange period, it is easy for us to become stressed and distressed by the circumstances. To help combat this, set aside some time daily to practice mindfulness and breathing exercises. Mindfulness can help us to reduce stress (7), something that we all will be facing to varying extents with the forced change in lifestyle. At Rewire, we have been developing a Mindset Recovery System. This involves guided box breathing exercises (a Navy SEAL technique) to help reduce stress (8) and binaural beats which help to counteract the negative effects of mental fatigue (9).

We have put together a demo of these to help with your mindfulness during this difficult time, which you can access using the following video.

To read more about the positive effects of mindfulness, click here.

Overall, it is incredibly important to stay healthy and active during these uncertain times. Try to create structure in your life where structure lacks and use this unique time effectively to improve yourself without social pressure.

Simple Ways to Improve your Sleep for Athletic Performance

The quality of our sleep has huge implications for athletic performance. Sleep is essentially the time when physical and mental recovery occurs. With good cognitive function and physical readiness being required for us to perform at our peak, it is obvious to see how it is important that we have good quality sleep to perform at our best.

Start listening to our circadian rhythms

“We are the supremely arrogant species; we feel we can abandon four billion years of evolution and ignore the fact that we have evolved under a light-dark cycle. What we do as a species, perhaps uniquely, is override the clock. And long-term acting against the clock can lead to serious health problems”

Professor Russell Foster

Our sleep patterns our guided by circadian rhythms, which essentially act as our body clock and determine the appropriate time for hormone release, which in the case of sleep is melatonin. With the invention of the light bulb and screens has come the ability to overcome this natural body clock. The presence of blue light reduces the secretion of melatonin, increasing alertness and keeping us awake. This delays the onset of sleep and reduces the amount of time that we spend asleep. By cutting out screens as you prepare to go to sleep you can ensure that your onset of sleep is faster and thus your time in bed is more efficient.

Think in cycles not hours

“Eight hours sleep is an average amount of sleep people get per night, and it somehow seems to have become a recommended amount – for everyone. The resultant pressure put on getting this is incredibly damaging and counterproductive to getting the right amount of sleep that we individually need”

Nick Littlehales

To maximise the quality of our sleep we should quantify sleep in terms of cycles, not hours. One sleep cycle lasts approximately 90 minutes and hence if we can time our sleep to wake up at the end of a cycle we can wake up at the lightest point of our sleep and feel refreshed and ready to start the day.

We should also not be too concerned about the amount of sleep we get each day but instead over the whole week. In his book “Sleep”, Littlehales suggests that we should be getting 35 cycles per week, averaging 5 cycles a day, which works out as 7 hours 30 minutes. This approach is much more achievable than consistently hitting 8 hours which can be quite pressuring and stressful and a cycle approach is reflective of how we actually sleep. Littlehales says that this approach reduces the stress hormones released from struggling to sleep and allows us to get effective rest and recovery.

Apps like Sleep Cycle ensure that your alarm wakes you up at the lightest point of sleep possible meaning that you wake up feeling refreshed and ready to start the day.

Be more consistent

Our body adapts to the time we fall asleep and thus by being more consistent, we can fall asleep quicker and ensure the time that we spent in bed is efficient. Not only is our sleep more efficient when we are consistent, but we also get more slow-wave and REM sleep – the times when physical and mental recovery occurs respectively. This allows us to maximise the benefits of training and perform at our best. 

Laura Kline, Rewire Athlete, tells us that by developing a consistent routine she has been able to ensure she gets adequate sleep. “By 8:00 I have my magnesium drink and try to limit my screen time. I aim to be in bed by 9:30 – I find that following a set schedule makes a difference as my body knows it’s time to shut down.” Laura says that by doing this she can typically fall asleep within minutes and on the inevitable days that she can’t follow her routine she notices a difference the next day. 

Optimising our sleep is not necessarily about getting more sleep, but about making the time that we spend in bed as efficient as possible. Only by working to improve the way that we sleep can we truly allow for sufficient recovery to develop our athletic performance.

The Science Behind Mental Toughness

Mental toughness can be defined as a personal capacity to produce consistently high levels of subjective or objective performance despite everyday challenges and stressors as well as significant adversities. (Gucciardi et al., 2015)

Clearly, mental toughness is a beneficial quality to have, it allows you to push past inevitable setbacks to achieve success. But how do we become more mentally tough?

In a study by Jones et al., 2002, athletes ranked 12 attributes of mental toughness in order of importance. Numerous studies, including this one, show that the most important attribute of mental toughness is self-belief in your ability to achieve goals. Self-belief in yourself can be developed through vicarious experiences – by watching others who have embarked on a similar path and have achieved success, you can develop the belief that you can achieve that same success yourself. What you believe about yourself and tell yourself are crucial to mental toughness, Rewire has integrated self-talk mantras to help develop this and in turn, build your mental toughness.

“This record was in my mind for a long time, I’m so happy to have made it reality today.”

Geoffrey Kamworor – On his Half Marathon World Record (2019)
Integrated Self-Talk Mantras in the Rewire app.

In this same study, athletes ranked ‘bouncing back from performance set-backs as a result of increased determination to succeed’ as the second most important attribute of mental toughness. One of the athletes involved with the study was quoted as saying ‘Nobody’s rise to the top is completely smooth, there are always little hiccups or turns in the road.’ Negative results provide increased determination as no one ever wants to be known as a ‘failure’. This increased determination coming from failure is a key part of mental toughness, it differentiates those who will never give up from those who will.

The third most important attribute of mental toughness was a self-belief that you possess unique qualities and abilities that make you better than your opponents. Rewire is all about developing qualities that set you apart from your competition by providing mental training so that you can develop your mental endurance above that of your competitors, allowing you to have that self-belief that you are better than your opponents.

‘Every quarterback can throw a ball; every running back can run; every receiver is fast; but that mental toughness that you talk about translates into competitiveness.’

Tom Brady

The fourth attribute, and the final one we will discuss, is the ability to remain fully focused on tasks in the face of competition-specific distractions. Numerous distractions can occur in competitions, causing your mind to be taken off the task at hand reducing your performance. Using Rewire helps to develop your mental focus. You are ranked on mental focus after every training workout, with the ability to track it over time.

The metrics available in the Rewire app.
The metrics available in the rewire app including Mental Focus.

Laura Kline, Rewire Athlete and Former World Duathlon Champion, tells us: ‘It’s not letting your mind wander and your legs slow down as it [Rewire] keeps you focused the entire time.’

To summarize, mental toughness is universally accepted as a key part of athletic performance, as Eliud Kipchoge says: “If you don’t rule your mind, your mind will rule you”. Mental toughness allows you to achieve high levels of performance even in the face of setbacks. It’s time we started to work on it….

‘If you run into a wall, don’t turn around and give up. Figure out how to climb it.’

How to use Self-Talk Mantras to Effectively Increase Performance

Does talking to yourself really help increase your performance? Yes! According to numerous studies, including this one from 2013, using self-talk significantly reduced an athlete’s rating of perceived exertion (RPE) – essentially how hard you feel you are working. This in turn led to a significant increase in time to exhaustion (TTE) meaning that the athletes could continue to work at the same intensity for longer (Blanchfield et al., 2013). In essence this means that by using self-talk techniques, you can increase your performance in endurance activities (or at least make it feel easier!).

So how can you use self-talk effectively to improve your performance? Pick four mantras, either from the list (below) or ones that you have created yourself. They need to be meaningful to you, so take your time to think about which resonate with you the most. 

Pick another two for the late stages of the race or training session suited for times when you can feel the lactic acid moving round in your legs and all you need to do is keep pushing and take your mind off the immense pain. Kline, the former World Duathlon Champion, says: “I might start a race with a mantra in my head ‘Calm and focused.’ And then I’ll reach a point where there’s going to be a lot of climbing and I’ll say ‘Consistent climbing’ over and over in my head. Then I’ll get to a point in the race where it’s go time… I’ll say ‘Bring it home’.”

Early Stage

  • ’Calm and Focused.’ – Laura Kline, Former World Duathlon Champion and Rewire Athlete
  • ’You’re doing great’ – Ryan Hall, Olympian in the marathon
  • ’Stay relaxed’ – Tyler Pennel, Former U.S. National Marathon Champion
  • ’Calm Confidence’ – Annie Bersagel, Former U.S. National Marathon Champion
  • ’Swift and smooth’
  • ’Steady forward momentum’
  • ’Your race. Your pace.’
  • ’Keep this up’
  • ’One step at a time’
  • ’You’ve got this!’
  • ’Feeling good’
  • ’Going strong’

Late Stage

  • ‘Bring it Home’ – Laura Kline, Former World Duathlon Champion and Rewire Athlete
  • ’Tough times don’t last, but tough people do’ – Ellie Greenwood, Western States Record Holder
  • ‘Just keep pushing’ – Ian Sharman, Former Winner of the Leadville Trail 100 Mile Run
  • ‘Whatever it takes’ – Ryan Vail, Former USA Cross Country Team
  • ’Never give up’ – Chrissie Wellington, Ironman World Champion (2007-2009)
  • ’Fortunate, Fearless and Fast’ – Payson McElveen, Professional Mountain Biker
  • Go faster. Push harder. Today, define yourself.’ – Deena Kastor, Olympic Marathon and Long Distance Runner
  • ’Beast mode on’
  • ’Breathe in Strength. Breathe out weakness.’ – Amy Cragg, Olympic Marathon and Long Distance Runner
  • ’Shut up legs!’ – Jens Voigt, Previous holder of the Hour Cycling Record
  • ’Push through this’
  • ’Consistent Climbing’ – Laura Kline, Former World Duathlon Champion and Rewire Athlete

The mantras that you have picked should be meaningful enough to you that you can remember them without any problem. However, you might wish to have an extra reminder. Write them on your hands or fingers if you need, or even engrave them onto the handlebars of your bike. The good news is with the Rewire system you can program your personal mantras right into the training app and they will appear during the most challenging points in your workout automatically. Throughout exercise use the phrases as and when you need, repeating them over and over, taking your mind off the pain.

Using mantras in the Rewire app

By using these mantras, your perception of how hard you are working will be lower and this will allow you to push yourself beyond the previous limit set by psychological factors, thus enhancing your endurance performance.

After a few sessions you will have become accustomed to using self-talk and will likely have naturally selected the mantra which fits the best for each part of the race, those being the ones that you repeat the most since they mean the most to you.

Keep pushing!
