Research investigating the impact of aerobic exercise on affect indicates that affect is significantly decreased during exercise at intensities above the ventilatory threshold, but returns to baseline levels or improves post-exercise. The literature to date regarding the effects of anaerobic exercise on affect is limited and has primarily focused on resistance training. Studies have not investigated the influence of a Wingate protocol on affect.
PURPOSE: Determine the impact of Wingate cycling trials on affect in participants consuming a caffeine or 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). Affective valence was measured at baseline, 40 minutes after consuming a caffeine (C) or placebo (P) beverage, immediately after, and 10 minutes after Wingate trials.
RESULTS: Data were analyzed using pairwise comparisons. Affect scores were similar between conditions at baseline (P = 3.3±1.5; C = 3.5±1.9; p > 0.05). Affect was unchanged for the placebo and caffeine conditions after beverage consumption (P = 3.5±1.3; C = 3.5±1.9; p > 0.05). Affect decreased significantly in both conditions after completing the Wingate sessions (P = 1.4±2.8; C = 1.1±3.0; p < 0.01). Affect increased in both conditions after 10 minutes of recovery (P = 2.2±2.4, p < 0.10; C = 1.9±2.2, p < 0.01).
CONCLUSIONS: Findings suggest that two trials of Wingate cycling significantly decreases affect in a sample of healthy adults immediately after exercise, and affect increases slightly, but not yet to baseline levels 10 minutes into recovery. The findings support the dual-mode model. These results also suggest that a moderate dose of caffeine has little impact on affect during exercise at the intensity of Wingate cycling. This study was done at extremely high intensity under controlled laboratory conditions. Future research on this topic should investigate an intensity that reflects exercise sessions typical of recreational exercisers and athletes.
