Effects of Designed Exercises According to 400m Aimed Race in Developing 200m Time ,First and second , and Reducing Time Difference Between Them

Abstract

Aim research To identify the distance time of completion of the 400 m race and partial time of distance ( first and second 200 meters first, and the time difference between them), and researchers supposed the existence of significant differences in the first and second a 200 m and the time difference between them , the human area included a group of racers who tried out for the 400 and the time domain: from 24/5/2014 until 14 /8/ 2014. And spatial domain: stadium of College physical education and Sport Science, University of Baghdad, researchers used experimental method on a sample of (8) racers , after viewing the results, analysis and discussion, the researchers concluded that in the time of the first and second 200 meters while not evolution in the time difference.
