8 to 12 weeks of aerobic high-intensity running training (>85% HRmax) improves VO2max (5-11%), running economy (3-7%), and yo-yo intermittent recovery test performance (13%) in football players.
To improve your fitness for football, incorporate 8-12 weeks of high-intensity running training twice a week. Aim for intensities above 85% of your maximum heart rate, using intervals like 4 minutes of running followed by 3 minutes of active recovery. This will boost your VO2max and your ability to recover between high-intensity efforts.
Studies on football players have shown that 8 to 12 wk of aerobic high-intensity running training (>85% HRmax) leads to VO2max enhancement (5% to 11%), increased running economy (3% to 7%), and lower blood lactate accumulation during submaximal exercise, as well as improvements in the yo-yo intermittent recovery (YYIR) test performance (13%).

More from this paper
- Speed-endurance training (repeated sprints) improves football-specific endurance (YYIR test 22-28%) and repeated sprint ability (~2%) more effectively than aerobic high-intensity training alone.Good
- Small-sided games and football-specific drills can elicit high-intensity physiological responses (VO2max, running economy) comparable to non-ball high-intensity training, while potentially offering greater football-specific performance benefits.Moderate
