What football conditioning actually is

Preseason arrives and someone sends the squad on a five kilometre run. It has been happening for fifty years and it is still the most common way footballers are conditioned.

It is not useless. It is just training for a sport that is not this one.

What a match actually demands

A footballer covers somewhere around ten kilometres in a match. That number is where the long run idea comes from, and it is misleading, because almost none of it is continuous.

The shape of it is this. Most of the game is walking and jogging. Scattered through that are somewhere between fifteen and thirty genuine sprints, each lasting a couple of seconds. Between them are hundreds of changes of speed and direction.

The moments that decide matches are almost all in the sprints. Getting there first, getting away, getting back.

So the real question is not can you run for an hour. It is this: how good is your tenth sprint compared to your first, and how quickly are you ready for the next one after each.

Why steady running does not answer that

A steady run trains your body to be efficient at one moderate pace. That builds a genuine base, and a base is worth having, especially for a player coming back from a long break.

What it does not build is the ability to produce a maximum effort, recover partially, and produce another one. It also does not expose you to the speeds where injuries happen, which means it does nothing to protect you from them.

Worse, a lot of slow running with no fast running is the exact recipe for a hamstring that has forgotten what top speed feels like.

What to do instead

Repeated sprint work

The most football specific thing you can do. Short maximum efforts with incomplete recovery.

Something like six sprints of thirty metres with twenty five seconds between them, three or four sets, with a couple of minutes between sets. Every sprint at full effort. Once the times drop off noticeably, the useful part of the set is over and you should stop.

Change of direction under fatigue

A shuttle rather than a straight line. Out and back, or a course with turns. This is the closest thing to what actually empties you in a match, because the turns cost more than the running does.

Intervals for the engine

Longer efforts of two to four minutes at a hard but sustainable pace, with equal rest. This builds the ability to recover between sprints, which is the part people mean when they say a player has a big engine.

Some steady work, in the right place

Genuinely useful in preseason, in the off season, and for recovery. Just not as the whole plan.

Where speed fits

Top speed running is conditioning, injury prevention and performance at the same time, and it belongs in the week whatever else you are doing.

Fresh, at the start of a session, in short doses. Two or three runs of thirty to forty metres at close to maximum, with full recovery between them. That is enough to keep the tissue exposed to the speeds it will meet on a Saturday.

Skipping it is one of the main reasons players get hurt in the first fifteen minutes of a match, and it is covered in more detail in why hamstrings go at full speed.

What it looks like across a week

In season, most of your conditioning happens at team training whether anyone plans it or not. What you add on your own should fill the gap rather than pile on top.

For most players the gap is speed exposure and repeated sprint quality, because team sessions tend to be full of moderate running and short of genuine maximum efforts.

One dedicated conditioning session in the week is usually enough alongside a match, and in a congested week it is often zero. That balance is the subject of training through a congested fixture list.

The test that tells you where you are

Run six thirty metre sprints, twenty five seconds apart, and time them.

Compare the last to the first. A small drop off is a well conditioned footballer. A large one means the engine that recovers between efforts is the thing to work on, whatever your five kilometre time says.

That is the number that matters in this sport, and almost nobody measures it.
