The Fitness Score

Our fitness depends on the ability to mobilize the body’s resources in response to physical stress. The fitness score is a combination of Functional capacity and Adaptability levels. Functional capacity is a fitness score component that reflects how well one’s body functions as a whole system. It is an indicator of general well-being, and may vary in response to stress and changes in lifestyle. Adaptability is a measure of efficiency of the cardiovascular system in response to physical activity. The “stronger” one’s cardiovascular system the higher is the level of adaptability. Adaptability can significantly improve with the right exercise program as well as with diet.

Fitness assessment is based on a simple 3-4 minute lying-to-standing test combined with Deep Breathing. This test provides a measurement of the level of Physical Fitness based on analysis of Heart Rate Variability (HRV).  What is Heart Rate Variability? Our heart rate is constantly fluctuating, and the intervals between heart beats vary in length.

  • Evaluate your initial fitness level
  • Monitor progress of your fitness training program
  • Notice any changes to the fitness condition
  • Immediately interpret test results
  • Can be used by any individual ranging from athlete to sick and elderly, as well as personal trainers and exercise physiologists Parameters for Fitness Score Assessment (see fitness chart)

These fluctuations in known as Heart Rate Variability.  Assessment based on Heart Rate Variability analysis is scientifically proven to monitor functional integrity of the body and give an accurate fitness evaluation.

How it works

The “Polar belt, which is fixed firmly around one’s chest, receives the heart rate signals from the body and records the intervals between heart beats and after that transmits them to the PC by bluetooth connection. The data is then analyzed by the Fitness Score algorithm and the result of analysis is displayed on the screen immediately after the test. The Fitness Score algorithm under previous name “Nerve-Express” was validated in Columbia University with excellent result. Validation study report you can find on .

 Fitness score part

This part displays results of the fitness test in a chart called Fitnogram. The horizontal axis of the Fitnogram consists of the 13 levels of Functional capacity  level, from the highest (#1) to the lowest (#13). The vertical axis shows 7 levels of Adaptability, #1 being the highest and # 7 – the lowest possible level. The current fitness level appears as a yellow dot on the chart. The chart has 3 main zones marked with color that are also described in the legend: blue (top fitness zone – professional athletes), light blue (average fitness zone), and red (below normal fitness zone).

Parameters for Fitness Score Assessment

  1. Functional capacity is ability of all regulation mechanisms, first of all Autonomic Nervous system properly maintain simple intervention to the body for instance lying-to-standing test(orthostatic test).
  2. Adaptation reserve of the body depends of 2 major components: –  CHMR – chronotropic myocardial reaction which is actually ability of the myocardium to increase Heart Rate in response on lying-to-standing intervention. CHMR directly related with the energy of a myocardium cells. CHMR directly related with the 1st phase of the Transition period(see picture below). ; – Compensation response of the peripheral vascular system on lying-to-standing intervention. Compensation mechanism of the peripheral vascular system is the ability properly compensate when blood pull down during  lying-to-standing interventions. Compensation response is directly related with 2nd Phase of the transition period(see picture below).



Functional Capacity: Levels 1 – 13

  • From highest (1) to lowest (13)

Adaptability: Levels 1 – 7

  • From highest (1) to lowest (7)
