Possibly, but I’d argue that’s not really positively impacting or shifting performance, apart from pacifying a coach - though that might be your point.
50 min runs? I still can’t believe players are given that kind of running to do!
One of the problems with more recent sports science is that physical performance data is being produced by the page full, but being looked at in isolation, painting a false perspective. It MUST be assessed alongside performance data.
As an example …
The four most important things to look at from a game perspective when assessing average speeds (m/min or km/hr) in team sports are …
- Number of runs (instances) at the higher speeds or speed zone specified
- Time of the runs during the game (not duration) when they occurred
- Proximity to effective action, (how effective that run was)
- Positive negative outcome
