Target: We aim to analyze of speed tests’ chronic effect on nitric oxide for footballers. Method: In the our study; we searched physical efficiency in 30-60 minute by medium stress and 3 days a week (for 8 weeks); and also at the beginning and ending of programme speed test was applied (20mt). While resting period and after the test; blood examples were sampled. Findings: In the test results before the program; before speed test serum NO levels were 25.5911 +1.5; after speed test result were 19.6161 2.0. This decrease on serum NO level does not have any meaning as statistical (p>0.001). In the test results after the program; before speed test serum NO levels were14.8348 +1.36 iken; after speed test result were 11.7881 + 1.30. This decrease on serum NO level does not have any meaning as statistical (p>0.001). Result: By the making sport regularly and efficiently; it makes strengthen hormonal system, immun system and cardiovasculer system, helps to increase muscle mass; but maximal exercises which made tired to body NO levels might be decrease. However; although decreasing on NO levels, we are expecting that rising on levels at the resting period.
