Percent fatigue in the mechanical variables during the Traditional and cluster set configurations. Values are means ± standard deviations

Mechanical variable	Traditional set	Doubles cluster set	Singles cluster set
F	2.3 ± 2.8	5.2 ± 4.5	4.4 ± 4.6
Impulse	15.6 ± 9.9	14.0 ± 6.2	12.1 ± 5.6
Work	3.6 ± 3.8	4.9 ± 4.6	4.5 ± 3.7
PO	10.4 ± 5.3*	16.7 ± 6.0*	11.6 ± 6.9
TUT	16.4 ± 9.8	15.8 ± 7.7	11.8 ± 5.9

Doubles cluster set = repetitions 1 and 2, 3 and 4 performed continuously with a 30 s rest between repetitions 2 and 3; Singles cluster set = four repetitions performed with a 30 s rest between each consecutive repetition; F = average concentric force; PO = average concentric power output; TUT = concentric time under tension.
