Table 2 Summary of instruments and variables used in research.
From: A comprehensive analysis of internal and external load monitoring systems in basketball
Variable type | Measuring instruments | Variable | Abbreviation | Definition | Measurement Units |
|---|---|---|---|---|---|
Coach-Prescribed Workload | Coach’s own system of session load planning | Coach-Planned Load | PCL | Estimated load of the session scheduled by the coaching staff before the training session | au |
Objective Interal Load | Heart Rate Band | Average Heart Rate | Avg HR | Average beats per minute | bpm |
Maximum Heart Rate | Max HR | Maximum value reached in beats per minute during the session | bpm | ||
Sum of the Heart Rate Zones | SHRZ | Weighted time in each heart rate zone, previously divided in five zones | au | ||
Subjective Internal Load | Rate of Perceived Exertion Scale | Rate of Perceived Exertion | RPE-CR10 | RPE Borg scale, using values from 0–10. | au |
Rate of Perceived Exertion per session | sRPE | RPE-CR10 scale weighted by session time in minutes. | au | ||
Kinematic Objective External Load | Inertial Devices | Distance | Dist | Total distance covered | m |
Explosive Distance | Expl Dist | Distance covered with an acceleration greater than 1.12 m/s2 | m | ||
High Speed Running | HSR | Number of times the player has exceeded the HSR speed | n | ||
High Speed Running & Sprint | HSR & Sprint | Number of times the player has exceeded the HSR or Sprint speed | n | ||
Maximum Speed | Max. Speed | Maximum speed achieved | Km/h | ||
Maximum Acceleration | Max. Acc. | Maximum acceleration achieved | m/s2 | ||
Accelerations and Decelerations | Acc & Dec | Total number of accelerations and decelerations | n | ||
Neuromuscular Objective External Training Load | Inertial Devices | High Intensity Actions | HIA | Number of high intensity actions | n |
Player Load | PL | Vector sum of accelerations recorded by the device in its three axes | au | ||
Impacts | Imp | Vector sum of the forces G supported by a player in all three planes | G | ||
Subjective External Load | SIATE | SIATE Task | ST | Quantitative variable obtained by adding the value assigned within six previous variables (1 to 5 points). | au |
SIATE Task Time Participation | STTP | It allows to know the load adjusted to the level of participation of the athletes. It is the Time Task Load per Effective Participation of the athletes. | au |
