Dear authors and readers,
It is our great honour to have chance to publish the first issue of our fifth volume with your contributions. Our journal is growing with your continuous support and reached to new level with its fifth volume. In this issue you will find 6 original articles by authors from Iran, Italy, Tunisia, and Turkey. For your future submissions please keep in mind that we will accept only sport related themes in our following issues. Once again, we are really thankful to all contributors, including our review team and international advisory board, who all work voluntarily to support our journal.
