In the previous post “This is how the electrical intensity determines the results of our training<\/a>” we made a brief analysis of the electrical intensities that are supported at the RPEs that we set at the beginning of the investigation (5\/10, 7\/10 and 8\/10) .<\/p>\n\n\n\n

We were able to verify that an average increase of approximately 20 mA could result in an increase of up to 50 bpm in heart rate; however, these results are averages of all participants. In the following image we verified that there was some variability (distance between points) for all muscle groups:<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

It can be seen that, for example, in the lumbar, dorsal and abdominal areas the variability is even greater at 7 Hz<\/strong>; however, we see that at 21 Hz the variability is reduced, although we continue to have disparity between participants.<\/p>\n\n\n\n

For example, if we analyze the abdomen at 21 Hz we see that there are people who support approximately 10 mA<\/strong>, while others are able to support up to 40 mA. The difference in these intensities can be due to different causes:<\/p>\n\n\n\n

    \n
  1. The physiognomy<\/strong> of each participant is different, so the body structure itself may not allow the electrodes to be completely tight to the body.<\/li>\n\n\n\n
  2. The diversity of electrostimulation suits<\/strong> used has been able to enhance the difference between body structures, with the use of the Slim Plus personal EMS suit<\/a> being the most affected, since the Revolution Pro shared-use EMS suit<\/a> allows us to adjust each electrode to each muscle group.<\/li>\n\n\n\n
  3. Body composition<\/strong> can affect the delivery of electrical current. The relationship between fat % and electrical current administration has been previously studied, and the higher the fat %, the worse conductivity<\/strong>, so a higher intensity is necessary.<\/li>\n\n\n\n
  4. The experience with electrostimulation<\/strong>. People who have had more experience with EMS require a higher electrical intensity to increase heart rate. They are more tolerant.<\/li>\n<\/ol>\n\n\n\n

    Assessment<\/h2>\n\n\n\n

    With the data we collected at Wiems Lab<\/a> we have carried out this same analysis, but the results are not entirely conclusive:<\/p>\n\n\n\n

    \"\"
    * To safeguard the privacy of our participants we have named them as P1, P2, P3…<\/em><\/figcaption><\/figure>\n\n\n\n

    We can see that each participant has 3 variables:<\/p>\n\n\n\n

      \n
    • With and without experience in EMS.<\/li>\n\n\n\n
    • Cantidad de tejido adiposo visceral (VAT).<\/li>\n\n\n\n
    • % fat measured with DXA.<\/li>\n<\/ul>\n\n\n\n

      Likewise, they were divided according to those who had endured greater electrical intensity in the lumbar, dorsal, and abdomen; and the value of the electrical intensity withstood.<\/p>\n\n\n\n

      Results<\/h2>\n\n\n\n

      We observed in both groups (people who endure more or less intensity) their experience or not with EMS.<\/p>\n\n\n\n

      In both groups we have people with high and low visceral adipose tissue<\/strong>. For example, in the group that has endured the least electrical intensity<\/strong> we have P3 with 361 grams of visceral adipose tissue and P2 with 145. Similarly, in the group that has endured the greatest electrical intensity<\/strong> we have people at P6 with 253 grams of adipose tissue. visceral and P7 with 185 gr. It should be noted that all of them are below 400%, so in no case could we say that there are people with a lot of visceral fat and people with very little. All of them are in normative values of visceral adipose tissue.<\/p>\n\n\n\n

      Finally, and as a result of the above, we have the % fat measurements<\/strong> that, in the same way, show a normative state of body composition for this population. The % fat values are between 14.3 and 34.2 %, which means that they are within the normal range for this population.<\/p>\n\n\n\n

      In view of the current results, we cannot confirm that there is a direct relationship between body composition and electrical intensity supported; and we cannot conclude that the experience with EMS is a determining variable for intensity regulation.<\/strong><\/p>\n\n\n\n

      In this sense, the new Wiemspro application for trainers has an integrated report for each workout on the intensity supported and the relationship with heart rate, weight and fat %. This new functionality thus helps us to answer the question with great ease: Does body composition affect the administration of electrical current?<\/strong><\/p>\n\n\n\n

      Conclusion<\/h2>\n\n\n\n

      The analysis carried out in Wiems Lab has been totally observatory. We wanted to check with a very small number of people if any trend could be seen. However, the data is not enough; For all these reasons, we conclude that:<\/p>\n\n\n\n

        \n
      • A priori there does not seem to be a relationship between body composition, experience with EMS and electrical intensity supported by the individual.<\/strong><\/li>\n\n\n\n
      • The variability in electrical intensity may be due to the fact that the person is not able to establish what is a 5\/10, a 7\/10 and an 8\/10 on the RPE scale.<\/li>\n<\/ul>\n\n\n\n
