Several players completed their end of season testing on Thursday after being put through a series of assessments.
Academy graduates Nyal Bell and James Hooper, as well as new recruit Donal McDermott, were amongst those who were put their paces at Huddersfield University.
The assessments included Vo2 Max testing and isokinetics.
The Vo2 Max test is a progressive fitness based running test which fully tests the player's aerobic energy system, while Isokinetics is a strength and muscular endurance test.
The results will help the club’s sport scientist, Kevin Gibbins, finalise their individual out of season programme, which the players will complete before returning for pre-season at the end of June.
