Power development analysis for the start phase of 100m

Abstract

Abstract Introduction: Short distance running is part of the maximum intensity cycling exercises, consisting of combined efforts, each step being performed as a result of a complete impulse, characterized by covering a distance in a shorter time. Objective: This study aims to follow the development of power for the start in short distance speed trials. Material and method: A 26-year-old male athlete, who has been practicing athletics for 14 years, participated in the study, based on the 100-meter flat sprint. The pre-test was performed before the preparation period, the intermediate test after one mesocycle (one month) and the final test after the second mesocycle (after 2 months). The evaluations followed the strength with which 4 exercises were performed (deadlift, clean, power clean and squat) of 6 repetitions each. At the same time, the length of the distance covered in the first three steps from the start was followed. During the two mesocycles, the athlete participated in specific strength development training. Results: After the two-month training period, statistically significant (p<0,05) improvements were observed in 3 of the 4 exercises, with clean improving from 575 W to 626 W, with deadlift from 560 W to 670 W, and at squat from 422 W it reached 676 W. Regarding the result obtained at power clean, an improvement was observed from 556 W to 557 W, statistically insignificant (p = 0.48). At the triple step, there were improvements both when starting with both feet at the same level and when starting with one foot before. Conclusions: Following the results obtained in the three evaluations, we notice that the training program was developed efficiently and that the results improved in all the evaluation tests.
