XXXX , endocrine, and immune marker response to a soccer match.

@entity908 @entity251 @entity121 @entity701
This study represents the first time that @entity121 , endocrine, and immune markers have been measured, together with activity profile, during a competitive soccer match. Seven semiprofessional soccer players participated in a competitive league match. Blood and saliva samples were obtained 1 hour before kick off and immediately postmatch. Global positioning system equipment was used to measure heart rate and activity profile data throughout the match. Percentage increase in @entity908 kinase (CK) and myoglobin (MYO) concentrations was correlated with the number of sprints performed during the match (r = 0.88, p = 0.019; r = 0.75, p = 0.047, respectively). @entity908 kinase increased by 84% (p = 0.17) from prematch to postmatch, whereas MYO increased by 238% (p = 0.05). Players performed 39    18 sprints during the course of the match. @entity701 increased by 78% (p = 0.103), whereas @entity251 increased significantly by 44% (p = 0.004). No differences were seen from prematch to postmatch in the @entity251 to @entity701 ratio, immunoglobulin (Ig) A, IgM, or IgG. Sprinting is correlated with changes in CK and MYO and may therefore be associated with @entity121 in semiprofessional soccer players.
