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; Rep = repetition; F = average concentric force; PO = average concentric power output; TUT = concentric time under tension.
Decrease between repetition 1 and 3 in Traditional set significantly different from increase in Doubles cluster set (p < 0.05)
Decrease between repetition 1 and 2 in Traditional set significantly different from increase in Singles cluster set (p < 0.05)
Decrease between repetition 1 and 3 in Traditional set significantly different from increase in Singles cluster set (p < 0.05)
Increase between repetition 1 and 2, 1 and 3, 1 and 4 in Traditional set significantly different from decrease in Singles cluster set (p < 0.05)
Increase between repetitions 1 and 3 in Traditional set significantly different from decrease in Doubles cluster set (p < 0.05)
