* Denotes significance at P<0.05.

^† Denotes significance at P<0.01.

TackA^Rest = tackling ability under non-fatigued conditions;

TackA^Fat = tackling ability under fatigued conditions;

Bench^REL = 4RM bench press expressed relative to body mass;

Chins^REL = 4RM chin-up expressed relative to body mass;

Squat^REL = 4RM squat expressed relative to body mass;

$\dot{\text{V}}{\text{O}}_2$ max = maximal aerobic power.
