We investigated the effect of “psyching-up” on force production during the bench press. Twelve men (mean age ± SD: 27.4 ± 11.2 years) and 8 women (20.9 ± 2.5 years) with strength-training experience performed 5 bench press repetitions on a modified Biodex isokinetic dynamometer during 3 interventions. The interventions were counterbalanced and included a free-choice psych-up, a cognitive distraction, and an attention-placebo. Peak force recorded after psyching-up (mean ± SD: 764 ± 269 N·m) was significantly different from both distraction (703 ± 282 N·m, p = 0.003) and attention-placebo (708 ± 248 N·m, p = 0.01). The mean percentage increase in peak force from distraction to psyching-up was 11.8% (6 to 18%, 95% confidence interval [CI]) and 8.1% from placebo to psyching-up (3 to 13%, 95% CI).
The results of the present study indicate that psyching-up may increase force production during the bench press exercise in participants with at least 1 year strength-training experience.
