Abstract

PURPOSE:

This study presents an exercise protocol utilizing movement patterns specific to rugby union forward and assesses the reproducibility of scores from this test.

METHODS:

After habituation, eight participants (mean+/-SD: age=21+/-3 y, height=180+/-4 cm, body mass=83.9+/-3.9 kg) performed the Bath University Rugby Shuttle Test (BURST) on two occasions, 1 wk apart. The protocol comprised 16x315-s cycles (4x21-min blocks) of 20-m shuttles of walking and cruising with 10-m jogs, with simulated scrummaging, rucking, or mauling exercises and standing rests. In the last minute of every 315-s cycle, a timed Performance Test was carried out, involving carrying a tackle bag and an agility sprint with a ball, followed by a 25-s recovery and a 15-m sprint.

RESULTS:

Participants traveled 7078 m, spending 79.8 and 20.2% of time in low- and high-intensity activity, respectively. The coefficients of variation (CV) between trials 1 and 2 for mean time on the Performance Test (17.78+/-0.71 vs 17.58+/-0.79 s) and 15-m sprint (2.69+/-0.15 vs 2.69+/-0.15 s) were 1.3 and 0.9%, respectively. There was a CV of 2.2% between trials 1 and 2 for mean heart rate (160+/-5 vs 158+/-5 beats x min(-1)) and 14.4% for blood lactate (4.41+/-1.22 vs 4.68+/-1.68 mmolxL(-1)).

CONCLUSION:

Results suggest that measures of rugby union-specific high-intensity exercise performed during the BURST were reproducible over two trials in habituated participants.
