Research investigating the impact of exercise on state anxiety indicates anxiety is decreased after aerobic exercise and unchanged or increased immediately after anaerobic exercise for up to 60 minutes. To date the modality of anaerobic exercise studied has been resistance exercise. Additional research has investigated the impact of caffeine on state anxiety and indicates an increase relative to baseline values following ingestion. Studies have not investigated the influence of a Wingate protocol on anxiety. Additionally, this topic has not been investigated with respect to caffeine supplementation.

PURPOSE: Determine the impact of Wingate cycle trials on state anxiety in participants consuming caffeine and a placebo.

METHODS: Thirteen healthy male participants (mean age = 22 yrs) completed trials of exercise including two 20-second Wingate cycle protocols. Each trial included unloaded preferred cadence pedaling prior to, in between, and after two Wingate efforts. Trials were completed after consuming a placebo or caffeine beverage (160 mg; mean 2.1 mg/kg*bw). An anxiety inventory was completed at baseline, 40 minutes after consuming caffeine (C) or placebo (P) beverage, immediately after and 10 minutes after Wingate trials.

RESULTS: Data were analyzed using ANOVA and pairwise comparisons. Baseline anxiety levels were lower than normative data for both groups (C = 25+5; P = 26+8; p > 0.05). Anxiety did not increase in the placebo condition (P = 25+4, p > 0.10) and increased in the caffeine condition after consuming the beverage (C = 29+9, p = 0.09). Anxiety increased significantly in both trials immediately after completing the Wingate sessions (C = 44+8; P = 45+9; p < 0.01). Anxiety decreased after 10 minutes of recovery in both conditions (C = 37+9; P = 38+8; p < 0.01), but was above baseline and normal values.

CONCLUSIONS: Findings suggest two trials of Wingate cycling significantly increases anxiety in a sample of healthy, low anxious adults and anxiety is reduced, but not yet back to baseline, ten minutes into recovery. These results also suggest the impact of a moderate dose of caffeine is limited and the supramaximal nature of Wingate cycling may overwhelm the impact of caffeine on anxiety levels. Such findings have implications for exercisers who participate in high intensity, short duration anaerobic exercise.
