| Popis: | Motor Imagery (MI) used as mental preparation is known to be effective in enhancing athletic performance. However, data about the efficacy of mental preparation on performance and neuromuscular control of subsequent reactive movements is lacking. The purpose of the present study was to investigate the effects of MI on performance in drop jumps and on leg muscle activities. Fifteen participants performed maximal drop jumps from 26 cm height with and without kinesthetic MI in a randomized order. Ankle and knee angles, EMG of soleus, gastrocnemius, tibialis anterior, vastus medialis, biceps femoris and ground reaction forces were measured. Directly after MI participants showed a 3% ( p < 0.05) higher performance index (PI = air time/ contact time) compared to control jumps. With regard to neuromuscular control participants showed higher pre-activities (PRE = 100 ms before touchdown until touchdown) in soleus (11%, p < 0.01) and in gastrocnemius (5% |
