      BACKGROUND: In ice hockey, skating is a combination of speed, power, and balance.&#xD;
      OBJECTIVE:The aim of this study is to examine the relationship between previous injury&#xD;
      history and on-ice and off-ice performance of elite male ice hockey players.&#xD;
&#xD;
      METHODS: This study was designed as prospective cross-sectional study. Fifty elite men's ice&#xD;
      hokey players included (n=50, mean age 23y 8mo, SD 5y 3mo). Off-ice performance measures were&#xD;
      30 m Sprint Test, Broad Jump Test, Push-up Test, Hexagon Agility Test, Plank Test. The 2&#xD;
      on-ice tests were 30m On-ice Sprint Test and Cornering &quot;S&quot; Turn Agility Test.The athletes'&#xD;
      history of injury were including previous injury site, type, number and the mechanism of&#xD;
      injury. RESULTS: In push up test, there was a significant difference in those who had left&#xD;
      hand and right knee injuries and, athletes who had dislocation were found to be statistically&#xD;
      significant (p &lt;0.05). According to cornering s turn agility test results, athletes who had&#xD;
      puck injury were found to be statistically significant (p &lt;0.05). In 30m sprint and hexagon&#xD;
      agility test results, athletes who had overuse injury were found to be statistically&#xD;
      significant (p &lt;0.05). There was a significant correlation between on-ice 30m sprint and&#xD;
      cornering s turn agility tests with broad jump test and also with off-ice push-up and plank&#xD;
      tests (p&lt;0.05). CONCLUSIONS: As a result of the performance tests, push up test might be a&#xD;
      distinctive test in determining the performance of the athletes after injury. Also on-ice&#xD;
      tests had a correlation with off-ice plank test which is the indicator of core muscle&#xD;
      strength.&#xD;

      We believe that the current performance and performance deficiencies of the athletes&#xD;
      determined and existing training programs will be arranged to eliminate performance&#xD;
      deficiencies. We wanted to raise awareness about whether there is a general deficiency in ice&#xD;
      hockey performance caused by past injuries and which exercises should be included in the&#xD;
      training program in order to overcome performance deficiencies.&#xD;
