Conditioning training in rugby can be done in many ways. As we are training with a view to improving performance on the field, the principle of specificity is important. While running laps and long distance-based running would improve aerobic endurance and fitness it may not the ideal preparation for rugby. Aerobic fitness is important for promoting faster recovery between intense maximal efforts and for moving the pitch without fatiguing but high volumes of aerobic endurance training may blunt gains in strength, power, and speed, and potentially give rise to overuse injuries (Brunker & Khan, 1994).
Game related high intensity interval training (GRHITT), small-sided games and rugby-specific circuit training are popular conditioning training methods used in rugby which can develop endurance while being specific to the demands of the game.
