EFFECT OF SELECTED PLYOMETRIC EXERCISE ON POWER, STRENGTH AND SPEED OF SHORT DISTANCE ATHLETICS PROJECT FEMALE ATHLETES IN CASE OF ASSOSA WEREDA BENISHANGUL GUMUZ, WESTERN ETHIOPIA

Abstract

selected plyometric exercise were important to improve physical fitness components.The main objective of this study was to examine the effect of selected plyometric exercise on power, strength and speed, on short distance female athlete trainees. To employ the study, by simple random sampling technique 22 experimental groups and, 22 control group totals, of 44 female athletes was selected to perform plyometric exercise for three months, three days per a week. And out of the total number of, 44 female athletes, 8, participants terminate the training coincidence from both groups due to this study subjects become 36. The Weight and height average of experimental group and control group were almost all similar that is (48.99kg ±1.94) and (49.36 ± 1.84) and, (1.56m±.0231 and 1.55m±.0102) respectively. Before training, both groups of ,18 athletes has done pre-test ( BJ , SJ of anaerobic power tests, sit up, wall squat strength tests, and 35m, 60m dash speed tests) and recorded. The selected plyometric exercise were implemented on the EG three day per week, (60) minutes per a day. After three months, post test measurement on the same parameters was taken. The difference between the tests were analyzed statistically, with paired sample t-test at (P<0.05) Consequently it was observed that selected plyometric exercise implemented on adolescence brought about significant improvements from pre-test and post test results of power, in which length and height of BJ and SJ test result were increased by a mean difference of, (4.11 at P=.000 and 4.27at P=.000) respectively Strength in which duration of sit up and wall squat strength test result was increased by a mean difference of (8.39 rep/seconds at P=0.000 and 7.83seconds resist at P=0.000) respectively. And. speed, in which duration to complete (35m and 60m) was decreased by a mean difference of, (0.51seconds at P=0.000 and 1.28seconds at P=0.000.) According to the result the investigator recommended that adding selected plyomtric exercise program helps to improve adolescence athlete’s power, speed, and strength performance.
