Introduction: Sports performance and all physical exercise depend on the
coordination of skeletal muscle activation by providing the strength and
power that translates into the ability of the movement. Today, it is generally
accepted that sprint performance, like endurance performance, can improve
considerably with training. Strength training, especially, plays a key role in
this process. Aim: The purpose of the study was to find out how the plyometric
exercises influence the development of elastic force improving stages of
speed running for the 30m; 30-60m and 60m. Methodology: This literature
was selected by different research sectors that are based on the internet like
„Jab Ref” „PubMed” „Google Scholar” „Medline” „Sports Discuss”. Our
study is focused on 39 subjects, students of the „Sports University of Tirana”
Students were separated into 2 groups. The average age of the participants
was 19-20 years. In our study we involve 1(one) experimental groups, respectively
this group was trained with plyometric exercises and the Control
group. In order to collect data for contact time, and speed running is used
these measuring instruments Brower Timing Systems 2010, Leonardo Mechanograph
® GRFP standard variant of STD. Results and conclusion: The
experimental group showed improvement in running speed for the 0-30m
distance with 4.7% m/sec for average group values. Compared to the Control
group, the results for this distance indicated for sig≤0.05. For the 30-60m distance
the speed improved by 3.96% m/sec for the average value in the group.

Compared to the Control group the results for this distance showed values
of sig=0.11 not significant for sig≤0.05. For the 60m distance, the speed was
upgraded to 3.53% m/sec for average group values. Compared to the Control
group, the results for this distance showed sig=0.08 for sig≤0.05. In control
group, the contact time indicator from the height 40cm showed correlation
with running speed for the three (3) measured distances where for 0-30m
with r = -0.605; 30-60m with values of r = -0.540 and 60m with values of r =
0.566. Based on the above results, the plyometric method applied in the experimental
group showed more correlation between contact time by h=40cm
and the running speed on acceleration phase 0-30m.
