Abstract
The purpose of this study was to determine the effect of intensity and specificity of muscle pre-activation on maximum force, leg velocity and vertical jump performance in athlete men. 13 athlete university students (weight: 70.61± 3.76 kg, age: 22.69± 1.75 years, and height: 174.84± 1.15cm) were selected. Subjects did exposure to five different protocols randomly in cross design method. Protocols were warming up alone, warming up and performing static half Squat movement with 60% and 90% of maximum force, warming up and performing vertical jump exercise with weighted vest that was 5% and 10% of one maximum repetition in each subject. The result by using analysis of variance (ANOVA) showed that vertical jump performance after performing protocol of 5% with weighted vest in comparison with warming up protocols was higher significantly (P=0.003). But in comparison to each two Protocols, despite apparent differences, no significant differences were found. In leg velocity Variable, results showed that performance after the performing Protocol of %5 and %10 weighted vest was significantly increased Compared with the warming up alone Protocol (P=0.02, P=0.04). In The maximum power variable, the results showed that the subjects' performance increased after performing each protocol and even after warming up protocol alone. In general, the results of this study showed that the using a special warm up (movement patterns) in the combine with the exercise intensity and load, cause significant increase in explosive performance
