Abstract

            The purposes of this research were (1) to study the effects of the 8-week incline plyometric training, plane plyometric training, and combined plyomatric training and (2) to compare the differences of parameters related to the anaerobic, acceleration and jumping abilities between before the training, after 4-week training and after 8-week training between each group. Thirty male participants were divided in three training groups. followed after  a  8 week  training program. The incline plyometrics (IP) group (n = 10) trained by performing consecutive jumps on an inclined surface (15°) while  the  plane  plyometrics  (PP)  group  (n = 10) performed the same jumps on a plane surface and combination plyomrtics (CP) group  (n = 10) performed the same jumps and performing consecutive jumps on an inclined surface (15°) all three groups trained three times per week. Anaerobic parameters were 30-second Wingate Test,  40 m sprint were measured by Smart Speed and vertical jumping were measured by Smart Jumping test all three groups

. The results of trainings were analyzed by using basic statistical test, and the ANOVA with repeated measures was applied to compare the differences between groups of variances. The significance level was set at 0.05. There were significant The anaerobic power (p-value = 0.01) incline plyometrics (IP) group  ( = 824.41) increased than  plane  plyometrics  (PP)  group  ( = 668.10). The flight time to contact time ratio during vertical jumps showed statistically significant (p-value = 0.01) incline plyometrics (IP) group ( = 0.2070) decrease than than  plane  plyometrics  (PP)  group ( = 1.0230) and The peak power output during vertical jumps showed statistically significant increases (p-value = 0.05) incline plyometrics (IP) group increased than  plane  plyometrics  (PP)  group ( = 3048.5000)

 There were no significant within groups on anaerobic capacity  acceleration vertical jump high and flight time during vertical jumps all three groups . There was also a statistically significant difference in flight time to contact time ratio during vertical jumps with Group 1 and Group 2 results lower than Group 3. There were no significant differences in anaerobic capacity, vertical depth jumps, and flight time among the three groups. The increase of jumping performance, after incline plyometrics should be taken into consideration by coaches, when they apply jumping exercise to improve explosiveness of stretch shortening cycle.
