Endurance is important in any sport,it is vastly different playing 36 holes of golf socially than playing 36 holes for money.
Playing in the park for eight hours playing five a side with jumpers as posts is still easier than running for ninety minutes in a formal game.
Perhaps the running without a ball business is for this reason,to simulate a real game.
Of course endurance is very important.
But you'll agree endurance is gained in the first stage of pre-season training, where EVERYTHING revolves around long sustained running at a steady pace.
But, there comes a time when long steady-pace running comes to an end in pre-season and the fast and shorter work begins with or without the ball.
Endurance training is not interval fitness training. In endurance training an athlete is teaching his body to use oxygen only (which is a slow-burning fuel) for energy, just like the marathon runners do.
In sprinting the body uses different chemicals stored in the body for energy plus ogygen especially near the end of the sprint.
Since a football player must have endurance and also be able to execute very fast sprints constantly throughout the game and be able to recover as quickly as possible, he needs to teach his body to produce, store and quickly replace those fast-burning chemicals the body uses for fuel in the sprints and hard runs as well as teaching his body how to be a more and more efficient ogygen-burning machine. Providing early and steady long running has helped a player gain endurance, inteval training during the rest of the season helps him get and remain fit.
Running players hard and long without breaks during the season proper is akin to disaster for fitness. This is the period the players must be kept fresh and just below 100% percent fitness so they don't peak too early. This is not the period for long running without rest breaks, particularly long, hard running.
Doing warm-ups with the ball, some stretching, some skill drills, playing a conditioned game and then a free game, then doing some sprints with rest breaks followed by a winding-down jog and stretching is more than enough to keep the players fit and fresh and a good training session.
