In the first part of this article, we discussed the limits of acceleration events to describe the high-intensity phases in team sports and which gpexe metric can be used instead.
The exercise analyzed takes place over the entire length of the pitch and consists in a sequence of three accelerations/decelerations from the beginning to the end of the pitch; each “fast and loose” sequence is followed by a 30-s recovery phase and repeated for a total of six times (see image).
Another topic that can be discussed is the opportunity to measure heart rate for additional information and a more in-depth analysis. On this topic, the same exercise provides us with an excellent example to highlight the limits of heart rate in team sports.
Heart rate is used as a measure to estimate oxygen consumption, which is ...
