Abstract

Elastic tubing attached to a barbell has been reported to enhance strength and power to a greater extent as compared to conventional barbells. The aim of this study was to investigate the effect of the additional elastic tubing to a barbell during a clean pull on peak power (PP), peak velocity (PV), and peak force (PF). Six competitive female weightlifters (Mean age = 16.7 +/- 2.1 years) performed 3 sets of 3 repetitions of the clean pull at 90% of 1 repetition maximum (1RM). Testing was conducted on three separate days: day one without elastic tubing (NT) and the other two days with two elastic tubing loading conditions (T10 and T20), in random order. No Tubing (NT) represents a condition where all resistance was acquired from the barbell (90% of 1RM). T10 and T20 represent conditions of combining elastic tubing at 10% and 20% of the subjects' 90% 1RM with a barbell (90% of 1RM). One-way repeated measures analysis of variance (ANOVA) was used to assess loading conditions on PP, PV, and PF. The results showed that there was a significant increase in all variables-PP, PF, and PV-between T10 and NT and between T20 and NT (p < 0.05). The results reveal that adding a 10% increment to 90% of 1RM appears to be the optimal training condition for increasing power, force, and velocity during the clean pull.
