Monitoring Week-to-Week Load Increase
Studies have shown that a large percentage of injuries are associated with rapid change in weekly loads (1,2,3), and when load increases by ≥15 % from the preceding week, the risk of injury increases by up to almost 50 % (2).
In the example below, we’ve used AthleteMonitoring.com to analyze the weekly load of a professional rugby team during a 4 months period. Exessive weekly load increases have been detected on 2 occasions, during which the players were at an increased risk of injury. In this example, the S&C coach wisely decided to reduce the load of the subsequent week, which allowed players to recover and limit the risk of injury.
To minimize risk, increase weekly loads very progressively (10% or week or less), monitor week-to-week load changes to detect excessive load increases, and when a spike in load occurs, immediately reduce next week’s load, as shown in the example below.
