This study aims to determine the forms of training that have more influence on increasing limb muscle explosive power in students SMK N 5 Pekanbaru . This study compared 2 forms of plyometric exercise to improve explosive limb muscle power. The form of pliometric training given is box skip training and incremental vertical hop training. This type of research was experimental with a nonequivalent control group design giving two different groups of treatments for two to try to increase vertical jumps. Data collection techniques used the test method namely pretest and post test. The research instrument used to measure the height of the jumping vertical jump is to test using a tool called digital jump meter. The results of the study there is a significant comparison of the effect between box skip training and incremental vertical hop training on explosive limb muscle power. At an average increase of 5.7 in groups 1 and 6.3 in group 2. These findings indicate that there is an increase in the average incremental vertical hop exercise which is more influential and significant for explosive limb muscle power and can help students to be faster in increase limb explosive muscle power.
