APP Overview

The fitness test score is displayed on the Fitness Chart. This chart graphically represents the results of the quantitative analysis of the client’s Heart Rate Variability during Orthostatic (lying-to-standing) test. This chart is the “instant snapshot”, immediately demonstrating the client’s fitness and functioning rating.
Our fitness depends on the ability to mobilize the body’s resources in response to physical stress. The fitness score is a combination of Wellness and Adaptability levels.

Wellness is a component of fitness that reflects how well one’s
body functions as a whole system. Wellness level is an indicator
of general wellbeing, and may vary in response to stress and
changes in lifestyle. Heart Rate Variability reflects functional
integrity of the body and is an excellent indicator of the wellness
level. Variations in heart rate create a wavelike structure of the
rhythmographic strip. Usually better wellness levels result in
more perceptible waves in the “portrait”, and wellness has been
called “the dance of the healthy heart”. You can compare the rhythmogram of a well-trained athlete
and an untrained individual below. As you can see, in the first
case, the variations in heart rate are more detectable while in
the second case the rhythmographic strip is almost flat: the beat-
to-beat intervals are of the same length. A wellplanned exercise
program can help you achieve your optimal wellness level.

Adaptability is the measure of efficiency of cardiovascular system in response to physical activity. This component of fitness shows the ability of the heart and the rest of circulatory system to adapt to physical loads. The “stronger” one’s cardiovascular system, the higher the level of adaptability. This component of fitness can significantly improve with the right exercise program as well as with diet.

These two components of fitness are complementary yet essentially different, and are assessed in two distinct ways. The level of Wellness is determined by analysis of Heart Rate Variability during the stationary phases of the test: the Supine and the Upright stages. The level of Adaptability is determined by the Transition period of the test. If you compare just the transition part of the rhythmographic strip of a well-trained and an unfit person you can see how the two curves are different. The basic rule is that the steeper and the deeper the transitional curve, the higher the adaptability level.

Wellness and adaptability levels do not directly depend on each other. A person with low ability to adapt to physical loads may still be able to efficiently manage stress in general. This combination would correspond to a low level of adaptability and a high level of wellness. However, in the majority of cases these two aspects of fitness show significant correlation, and higher levels of adaptability correspond to higher wellness levels, indicting higher fitness overall.

If a client is not at his or her top performance level, an effective, well-designed exercise program with a personal trainer will result in a noticeable increase in the level of adaptability, and, if combined with the healthy lifestyle, in improved wellness level.

The fitness chart shows 13 levels of wellness on the horizontal axis, #1 being the highest and #13 being the lowest possible level. There are 7 levels of Adaptability, which are displayed on the vertical axis; with #1 is the highest level and 7 being the lowest possible level.

The chart contains three distinct zones selected with different colors:

the dark blue zone in the top left corner corresponds to athletic fitness levels; the light blue zone in the middle of the chart reflects average values of fitness in the general population, and the red zone in the bottom righthand corner represents very poor fitness levels that are below normal.

Your client’s fitness score is marked with the yellow dot. For example, the figure on the right shows a fitness score of a regularly exercising person. His wellness level of 6 is average among the general population. However, his adaptability level of 2 is above the average closer to athletic levels.

Interpreting test results

The test results are displayed on the screen so that you and your client can view his or her fitness score. However it is important that interpretation of the results is performed only by a fitness professional. The results should be interpreted depending on the client’s base fitness level, his or her age group and health condition. The same fitness score can indicate an improvement for one person and be a sign of overtraining for another individual. Individual clients should not change the training program based on the score alone, but should always consult with their personal trainer or exercise physiologist. Only a fitness specialist would be able to decide whether the training program should or should not be altered and choose an optimal solution for improving the client’s fitness.


If the fitness score is at the lowest levels of wellness and adaptability (within the red zone), this is a warning sign and needs immediate attention. The client should not exercise on the day when such a result is detected and is advised to consult a fitness or health care professional before engaging into any physical activity.

Detecting over training and undertraining

The fitness assessment with Fitness Score device can detect any of these conditions that adversely affect the client’s performance and fitness level. In both overtrained and undertrained persons see the fitness score is significantly reduced and are shifted towards the bottom right-hand corner as shown on the pictures below. THE MARKERS OF OVERTRAINING At the early stages overtraining is typically marked by a reduction of the wellness level with the retention of normal adaptability level. At the exhaustion stage the reduction of the wellness level is usually accompanied by a significant reduction in adaptability. The figures on the right show anathlete’s response to overtraining. You can compare his fitness scores at his normal state, at the early stage of overtraining and at the state of exhaustion.


The test results should be interpreted by a fitness professional only who is qualified to make a conclusion whether the test detected overtraining or undertraining.

Detecting effect of other factors

A reduced fitness score can also reflect a client’s response to other common factors such as stress at work or in other aspects of life, and even to increased alcohol or coffee consumption. Compare the fitness results of the same person before and after alcohol consumption:
