Lesson #10. Cardio training with online monitoring of lactate levels and calculating training impulse

Online training impulse calculator—a tool for calculating of training impulse (TRIMP) in real time during the training exercise with monitoring heart rate (cardio). Calculates the current value of TRIMP obtained by the athlete during the training with constant monitoring of the heart rate in real time using a sensor.

The initial data for the calculation are the current time and the current heart rate read from the sensor. The athlete’s PhA is used to calculate in real time the model value of the current concentration of lactate in the blood and then when calculating TRIMP.

This video lesson demonstrates the implementation of technological blocks Unit 6 and Unit 8 with optimal planning of the training process.


    With the optimal planning of the training process based on TRIMP technology, the coach and other specialists of the coaching staff should be able to solve a number of practical problems. The following list of these tasks determines the necessary conditions for the practical implementation of the training process optimal planning based on the physiological avatar technology and the training impulse.
    Unit 1. Maintaining an individual physiological profile (IPP) for each athlete of the coaching group (team). The IPP should contain data from standard anthropometry, as well as estimates of the maximum and minimum values of TRIMP (wmin,wmax).
    Unit 2. Maintain an individual sports calendar for each athlete in the team, indicating days of competitions as well as “special” days when the competitive or training load cannot be performed or has to be limited (days of illness, injuries, relocations, etc.).
    Unit 3. Keeping a journal of physiological observations (JPO) for the team and for each athlete in the format of observation packages of the “Physiological Avatar” technology. The data of the JPO are necessary to create the current collection of the athlete’s PA. Maintenance of the JPO requires a modern laboratory of sports medicine equipped with necessary measuring equipment.
    Unit 4. Managing the process of creating and using the PA collection for each athlete in the team. PAs are created in the identification factory on the basis of initial data of the IPP and the JPO. For each team athlete, at least one current PA must be created.
    Unit 5. Keeping for each athlete in the team his/her athletic form log. This log records expert judgments of the athletic form by the results of competitions, or by results of special tests that are similar to the conditions of actual competitions.
    Unit 6. Keeping for each athlete in the team his/her training load log. The log records TRIMP values achieved by the athlete during training exercises with physical exertion, and also during competitions.
    Unit 7. Designing optimal current training plans for each athlete in the team. Recalculation of the optimal current training plans for the new current data, i.e. realization of adaptive optimal planning of the training process.
    Unit 8. Implementation of current training plans by assigning training load to athletes in accordance with the planned daily value of TRIMP.

This work is devoted to the theoretical justification of a software and technological product that combines latest achievements in the field of mathematical computer modeling, sports physiology, and medicine. We present a review of theoretical foundations and practical solutions of the latest software and technological developments in the field of control over the training process in cyclic sports. We propose a new integrated approach to the training process planning, which combines known technology of the training impulse and a method for modeling individual physiological properties of the athlete’s body on the basis of the physiological avatar technology.
