Abstract

The aim of the study was to compare the levels and relative responses of C-Reactive Protein (CRP) and Skin Temperature (Tsk) of the lower limbs (LLs) of elite soccer players following three consecutive games with short intervals (< 4 days). Eleven male professional athletes (age, 29.26 ± 4.52 years) from an Brazil elite team were evaluated, with measurements obtained before (Baseline), and at Post-Games times (24, 48 and 72h). CRP and Tsk levels at 24 h and 48 h Post-Games times were higher than Baseline levels (CRP, p < 0.001, d > 0.9; Tsk, p < 0.04, d > 0.58), additionally, the levels of these variables (CRP vs. Tsk) showed positive correlations (p < 0.05, r = 0.60-0.88). The relative responses these variables were evaluated (Δ%CRP; Δ%Tsk). The 48h responses of Game 3 are respectively higher than 48 h responses of games 1 and 2, in Δ%CRP (p < 0.03; G3 vs. G1, r = 0.66; G3 vs. G2, r = 0.88) and in Δ%Tsk (p < 0.003; G3 vs. G1, r = 0.88; G3 vs. G2, r = 0.88). The 48 h Post-Game time seems to represent valuable contributions to understanding the development regarding the magnitude and duration of inflammatory processes associated with recovery. Additionally, the positive correlations that were verified allow an increase in the robustness of the analysis of the load of consecutive games through CRP and Tsk of the LLs. Then, these results indicate a physiological stress and a probable cumulative effect of the game loads due to short intervals (< 4 days), which is reinforced by the verified outcome of the Total Distance covered (G3 < G2, p = 0.003; r = 0.88). These findings can contribute to better load control and greater robustness of injury prevention programs.

摘要

本研究旨在比较 3 场连续比赛且间隔时间较短(<4 天)后,精英足球运动员的 C 反应蛋白(CRP)水平和下肢皮肤温度(Tsk)的相对变化。评估了来自巴西精英队的 11 名男性职业运动员(年龄,29.26±4.52 岁),分别在比赛前(基线)和比赛后 24、48 和 72 小时进行测量。比赛后 24 和 48 小时的 CRP 和 Tsk 水平均高于基线水平(CRP,p<0.001,d>0.9;Tsk,p<0.04,d>0.58),此外,这些变量(CRP 与 Tsk)的水平呈正相关(p<0.05,r=0.60-0.88)。还评估了这些变量的相对变化(Δ%CRP;Δ%Tsk)。第 3 场比赛的 48 小时反应分别高于第 1 和第 2 场比赛的 48 小时反应,在Δ%CRP 方面(p<0.03;G3 与 G1,r=0.66;G3 与 G2,r=0.88)和Δ%Tsk 方面(p<0.003;G3 与 G1,r=0.88;G3 与 G2,r=0.88)。比赛后 48 小时似乎对理解与恢复相关的炎症过程的幅度和持续时间的发展具有重要意义。此外,验证的正相关允许通过 CRP 和 Tsk 分析连续比赛的负荷,从而提高分析的稳健性。然后,这些结果表明,由于间隔时间较短(<4 天),比赛负荷会导致生理压力和可能的累积效应,这一点得到了总距离覆盖(G3<G2,p=0.003;r=0.88)的验证结果的加强。这些发现有助于更好地控制负荷并提高预防损伤计划的稳健性。
