Monitor and manage your sport performances

inCORPUS® measures an athlete's energy capital to assess their physiological condition based on a multidimensional analysis of the HRV. For each trainer, it is the digital tool for remote monitoring of the training of his athletes. For each athlete, it's the diagnostic tool that allows him to stay in shape from a distance.

inCORPUS® offers customized and specific remediations for each shape profile. There are five types of remediation, available exclusively by subscription:

  • Type of training sessions (endurance, intermittent, explosive...)
  • Nutrition (amino acids...)
  • Hydration (...)
  • Energetic care (cryotherapy, hydrotherapy, massages...)
  • Frequency of inCORPUS® tests

Eight energy profiles, the key to your performance

The orthostatic test allows inCORPUS® to identify eight energy profiles which correspond to the functioning of your autonomic nervous system (ANS) at the time of recording. The functioning of the ANS is automatic - it controls your heart and numerous other vital functions of your body and is an essential element in your sport performance 1,2. Numerous factors may influence the outcome of the orthostatic test such as physical and psychological stress, sleep deprivation, dehydration, unrevealed pathology, changes in the environment (altitude, temperature), etc. That is why it is essential to perform the orthostatic test in standardized conditions: in the morning, after waking up, with an empty bladder, while fasting, in a quiet environment with no disturbances (such as music).

Why "supine and standing" positions?

The autonomic nervous system comprises the parasympathetic and sympathetic nervous systems:

  • The parasympathetic nervous system (also known as the rest and digest system) activates regeneration processes, recovery and energy stock build-up. It normally is the dominant system at rest, during the supine phase of the inCORPUS® test.
  • The sympathetic nervous system (also known as the fight or flight system) activates energy expenditure, draws from energy stocks and is responsible for physical activation. It normally is the dominant system during the standing phase of the inCORPUS® test.

Why ten minutes?

The energy profile determined using the orthostatic test is based on average heart rate and heart rate variability measures, in the supine and the standing positions.

Heart rate variability by inCORPUS® is based on frequency analysis in which the high and low frequencies are isolated from the original recording. The high frequencies reflect the heart's parasympathetic modulations, while the low frequencies reflect its sympathetic modulations 3. This analysis is the best to analyze simultaneously the para- and sympathetic nervous systems.

The time-domain analysis (as opposed to the frequency-domain analysis), such as the root mean square of the successive differences (RMSSD) for example, analyses only the parasympathetic system and therefore cannot detect an imbalance between the para- and sympathetic systems, nor can it identify energy profiles 4.

"The frequency-domain analysis is the best way to analyze the para- and sympathetic nervous systems simultaneously, both of which are essential to performance."

As indicated by its name, the frequency-domain analysis is all about studying the frequencies of the waves present in the heartbeat recordings. To reliably analyze a wave, its waveform needs to be repeated at least ten times. In the case of HRV, the slowest wave (thus the one that repeats least often) completes its cycle every 25 seconds; and to record it ten times requires four minutes. Taking into account that a prior minute of recording is used to obtain a steady heart rate, one needs five minutes of recording in each position, therefore the orthostatic test requires ten minutes as scientifically demonstrated 5.

Supine position only?

However, ten minutes in the morning of a busy day can be too much.

Therefore, inCORPUS® allows recording of the supine position only (5 minutes). In this case, six out of the eight energy profiles can be identified. Two energy profiles can be detected only in the standing position - they deal with orthostatic hypotension (blood pressure regulation problems that could result in dizziness, lightheadedness, or even vagal episode) and physical activation problems.
