Professional soccer player’s creatine kinase concentration and 4-point Verbal Rating Scale scores.
We investigated the association between pain and creatine kinase levels to assess the risk of muscle injury after a professional soccer match. 80 players from a professional soccer club in the first division of the Brazilian football league were evaluated during four full seasons. They were assessed 36 to 48 hours after the match and followed up for muscle injury over the next five days. The assessment consisted of blood sampling for CK analysis and application of The 4-point Verbal Rating Scale (“no pain” on the far left and “pain in a specific area of the muscle” on the far right). The data shows injury occurrence, injury location, CK concentration and pain score. It can be used to draw conclusions about muscle injury predictors.
