Objective The purpose of this study is to propose and validate a strength and conditionning test for rugby training: the 15″/1′. Method This test is as close as possible from the rugby effort model, there are six sequences of 15 seconds running at maximal intensity divided by one minute active recovery. Running distance is measured during each sequence, the mean performance is calculated over the six sprints. A fatigue index represents subjects capacity to maintain their maximal performance with the repetitions. Seventy-seven rugbymen, N2, N1 and Pro D2 players, participated to this study. Their results have been analysed according to the performance level and the field position of the players. Results The results show significative influence of performance level and field position on the maximal distance performed during the first sequence and the mean performance calculated over the six sprints. On the other hand, fatigue index was not significantly different whatever the performance level and the field position of the players. Conclusion Present results demonstrate that the 15″/1′ test can be used to evaluate the rugby players.
