The present investigation was to determine if combining two mental preparation strategies would be more effective than a single strategy. In Experiment 1, subjects (n=40) performed basketball free-throws (20 shots) using one of these mental strategies: 1) imagery, 2) relaxation, 3)relaxation plus imagery, 4) placebo control. Results indicated a significant main effect with the imagery group performing significantly better than the placebo control group. In Experiment 2, subjects (n=40) performed five trials on an isokinetic leg-strength task using one of the following mental strategies: 1) preparatory arousal, 2) imagery, 3) preparatory arousal plus imagery, 4) placebo control. Results indicated a significant trials main effect with all subjects improving over time. State anxiety results indicated that the combination group exhibited higher levels of anxiety than all other conditions.
