Background

There is limited information available regarding the effects of caffeine-containing drinks on high intensity exercise performance. We hypothesized that Redline® energy drink would significantly increase (p<0.05) muscle explosiveness in bench throws (BT) when compared to an identical placebo (PLB) in recreationally fit subjects (n=16).

Methods

After a day of dietary control and caffeine abstinence, otherwise fasted subjects performed four individual ballistic bench throws under two conditions (Redline®, PLB), with trials being separated by 48-96 hours. The peak force (FOR), peak power (POW), peak velocity (VEL), peak displacement (DSP), and maximum rate of force development (RFD) of the Redline® trial were compared to PLB.

Results

Early results suggest a significant increase in FOR (Redline® 329.6 ± 108.8 N vs. PLB 322.9 ± 107.1 N [p= 0.015]); POW (Redline® 468 ± 177 W vs. PLB 446 ± 175 W[p= 0.001]); and VEL (Redline® 1.82 ± 0.18 m/s vs. PLB 1.76 ± 0.19 m/s [p=0.0035]); and a trend in the data (p<0.10) for DSP (Redline® 0.92 ± 0.08 m vs. PLB 0.90 ± .10 m [p= .0665]); and RFD (Redline® 529 ± 262 N/s vs. PLB 493 ± 219 N/s [p=0.0685]).

Conclusions

These preliminary data supported our hypothesis that muscle explosiveness in the bench throw would increase under the influence of Redline® energy drink.
