![]() have taken an unusual amount of collisionsĪny combination of these factors might be time to substitute that player out.Match substitutionsĭuring a match, the data for the tracker can be used to make decisions about substitutions. If they suddenly start to exceed this baseline, particularly if their heart rate does not appear to be recovering, it may be time to rest that player and potentially spare them an injury. One of the primary uses for tracking systems is to manage a player’s workload to make sure that they stay healthy and able to perform at their peak for the entire season.Įvery player will have a baseline set up throughout the season for collisions, heart rate, meters run per day, etc. If you’re interested in geeking out on the technical details, this research paper has more about the different technologies. They may need to back off a little on training for that day. Let’s say that a player’s heart rate hasn’t returned to baseline after a break in one of the early sessions. This monitor is also useful during training. If a player’s heart rate is unusually accelerated during a match, they may need to be substituted so as not to hurt the general performance of the team. whether they have recovered from a previous day’s workouts.whether they can keep playing or need to rest.Heart rate and heart rate recovery is the single best way to tell The heart rate monitor provides information about the player’s work intensity and fatigue levels. The gyroscope and magnetometer give much more nuance to the data regarding tackles and other collisions during a match. Without these two devices, the accelerometer would just give very raw information about changes in force and speed. Similarly, the magnetometer gives orientation to accelerometer data, but by using the magnetic field of the earth instead of gravity. This gives additional depth to the acceleration changes by providing information as to the directional change and rotation caused during collisions. ![]() The gyroscope uses gravity to give orientation to the data provided by the accelerometer. The coaches and trainers can use this data to understand the amount of physical punishment a player is taking. It can also measure the force when a player joins a ruck. This can be taking or receiving a tackle. ![]() It gives a reading as to sudden changes in force caused by direct contact, acceleration, and deceleration. The accelerometer helps to keep track of collisions.
