Post-Effort Chances in C-Reactive Protein Level Among Soccer Players at the End of the Training Season

Abstract

Numerous literature data point out the differences in immunological parameters as a result of physical effort and the relation of those changes to the subject's fitness level. This study was aimed at the assessment of soccer players' condition and adaptation to physical effort based on the changes in C-reactive protein (CRP) blood level. C-reactive protein, total protein, and albumin plasma levels before and after 60-minute-long outdoor running were determined among 16 (8 men and 8 women) soccer players. Statistically significant increase in total blood protein level was observed in both studied groups. However, there were no statistically significant changes in albumin level in soccer players' blood. Determination of CRP showed that the exercise test caused changes in its level among both women and men; yet, statistically significant increase in CRP level was found only in women's blood. The different influence of effort on CRP plasma level may be explained by the involvement of various mechanisms in regulation of acute-phase responses in different conditions. It was found in our study that CRP level could be a valuable tool to assess the metabolic response to aerobic exercise.

Effect of Aerobic and Anaerobic Exercise on the Complement System of Proteins in Healthy Young Males

“…It is known that all-cause and especially CVD mortality negatively correlate with both cardiorespiratory and muscular fitness levels in adults [67,68]. The research on CRP as the marker of inflammatory status regarding physical activity confirms the anti-inflammatory effects of this protein [50,69]. In another work [69], Phillips et al found that C3 concentrations were positively associated with increasing sedentary behavior and negatively associated with increasing moderate to vigorous physical activity.…”

“…The calculated ratio measures provide further evidence that each form of exercise presents a markedly different stress stimulus (Figure 1). Moreover, only the RSA test caused CRP corrected for plasma volume loss level to increase, while TP and albumin changes were related with post-effort dehydration before a return to baseline values during recovery (Table 3) [50,51]. On the other hand, the lack of a significant decrease in C2 and C4 protein level following the Beep test lends support to an alternative pathway of complement activation [8].…”

Post-Match Changes in Muscle Damage Markers among U-21 Soccer Players

“…It appears that CRP may not be a useful muscle damage marker for monitoring fatigue and recovery immediately following a soccer match in U-21 players. However, in their study, Kostrzewa-Nowak et al (2015) stated that CRP levels could be a valuable tool to assess the metabolic response to aerobic exercise. Because the post-match infl ammatory response of CRP levels has a 24-hour peak (Ispirlidis et al, 2008), this time-course could be considered as a valuable tool for assessing fatigue in soccer players.…”

The Influence of a Health-Related Fitness Training Program on Motor Performance as Well as Hematological and Biochemical Parameters

“…The significant increase in CRP level among the participants in the current study is consistent with the enzymatic profile described above and indicates that the training program caused muscular damage, therefore inducing pro-and anti-inflammatory responses. These responses provide further evidence that CRP is involved in the systematic responses to exercise-induced inflammation [54,55]. These processes stimulate muscular regeneration processes, so it can be considered as a positive effect of realized training program.…”
