Electrodermal activity measurement provides athletes with new information

Different kinds of physiological measurement systems have been used for a long time in top sports. Wearable devices have made exercise tracking easy for everyone.

Heart rate monitoring is the most used measurement in sports. It was developed by an Australian physician Robert Treffene for swim exercising. In Finland hear rate monitor was invented by the Polar Electro founder, professor Seppo Säynäjäkangas in 1975.

Today there is a huge variety of equipment for hear rate monitoring. The most accurate ones still measure from chest, either with a band or with taped sensors. Wrist worn trackers are comfortable to wear and they have largely displaced chest bands especially with non-professional exercisers. The accuracy of wrist worn trackers has been improved in past years, but it suffers especially at high heart rates.

Heart rate, heart rate variability (HRV) and electrodermal activity (EDA)

Analysing heart rate gives a good view of physical strain. With different algorithms it is possible to understands also recovery, sleep and stress.

Heart rate variability (HRV) has been lately brought up especially in measuring non-physical load. There are challenges, as at high heart rates the algorithms struggle to understand what happens: is the person physically at rest, but nervous (e.g. about a soon-to-start exam), or is it now about physical exercise? Here the accelerometers, present in all of the trackers, are of help. These components can detect whether a person is moving or is at rest, and much more about movement directions and pace.

The electrodermal activity (EDA) measurement brings interesting new information to analyse performance of an athlete. This does not tell about heart, but about sympathetic nervous system activation through sweat gland reactions of skin. Skin is the only organ that is purely innervated by the sympathetic nervous system. The EDA measurement is very sensitive to emotional and cognitive stress, and it has been used in psychological research already for over 100 years. Only lately it has become available for consumers.

The Moodmetric smart ring measures electrodermal activity. The ring is comfortable to wear and it is thus well suited for continuous, long term measurement. Only a sufficiently long measurement period gives a full picture on stress, how it is generated and how recovery happens during weeks, months and even years.

Both top sports, and going after personal goals in exercising benefit of stress load related information. It is good to understand what sources of stress or recovery might affect the performance. For instance, cognitive load of a professional athlete might be less than for someone who need to have a day job to finance the sports career. The professional athlete can probably exercise more, as there is more time for recovery. The results and performance are affected by emotional and cognitive load, if there is no time to unwind.

How can Moodmetric help an ambitious achiever?

Are you, or would you like to be a high achiever? Do you have the emotional power to handle it?

Some high achievers are always in pursuit of perfection. They are driven by an inner voice that is never content with their achievements. No matter how good are the accomplishments looking from outside, in the inside the person never feels good enough. There would always be room to improve, and more to do. Self-criticism is at maximum. Showing weakness is not an option. The pursuit of perfection is emotionally consuming. The tiredness is sometimes overwhelming, worsened by the disappointment in self, and others.

People in healthier pursuit of excellence are high achievers, whose inner voice is their genuine self. They have a  strong desire to accomplish something important, and gain gratification from success in demanding tasks. Their approach to good achievements contains more empathy, towards themselves and people around them.

They are self-assured but not self-centric. They are able to ask advice when needed, and understand the power of working together. Still, achieving much is a tough task and sometimes they can be on the edge emotionally.

The both types have one problem in common – how to tell when too much stress is going to make the path of productivity too rough?

Moodmetric services are aimed at high performing individuals, who want to optimize the use of their emotional capacity. Persons demanding a lot from themselves want to know where their personal limits are. How much more can I do and achieve, before the stress turns against me? The Moodmetric ring is a simple tool to measure long term data about how emotional load is affecting the wearers’ sympathetic nervous system. The trends are visible in a simple to read index, which shows the emotional load day-to-day.

The Moodmetric app also includes real-time follow-up on stress levels. This gives an instant view to reactions and stress amount during the day. A simple guidance teaches the wearers to understand their data in the daily context.
Moodmetric helps the wearer to understand the emotional boundaries. The Moodmetric ring and app are a very special and personal tool in building the optimal performance.

New technology for workplace wellness

Meditating business partners

Emotional health as a part of workplace wellness programs has begun to enter organizations. Active tracking and measuring are also new to employee health. Moodmetric combines all this and brings emotion measurement to the office.

The Moodmetric technology is based on measuring small conductivity changes in skin which tell about emotional reactions. A smartphone app gives you both live data and long term trends. Moodmetric helps to manage stress by identifying high and low activity of mind during the day.

Moodmetric provides a simple and nonintrusive way to measure emotional load at work. It also supports in meditation and mindfulness exercises.

 

Examples for workplace

Below are examples on how you can support emotional well-being at work with Moodmetric measurement. You can enhance your wellness program by adding this new component to it – work together with your employee health partner to create the best program for you.

Measuring emotional wellbeing

Using the Moodmetric ring for 2-4 weeks gives a good picture of emotional load and how it is distributed over workdays. Stressful meetings, and calm periods of the days are well visible. The daily average figure shows if there is a shift towards higher or lower emotional levels during the measurement period. Analyzing the results together with a coach or a psychologist helps to better understand the current state of mind at work.

Stress management training programme

Are you already aware that you experience a heavy emotional load? You can wear the Moodmetric ring at work for 1-2 weeks and meet with you coach once a week. An individual programme can be drawn based on measurement results. It can combine mindfulness and breathing exercises, small breaks outside – all during the working day. A second sequence of the Moodmetric measurement can be done in one to two months.

Measuring mindfulness or meditation

The Moodmetric app contains an exercise to measure calmness of mind. A clear curve is drawn during meditation showing how well the focus is kept. This is a great tool to take a measured break, even for 10 minutes during the day. Any disturbing thought declines the performance, so the result motivates to really clear the mind. If you are new to meditation or mindfulness, it is good to start with a guided exercise.
