Abstract

Background: Overtraining (OVT) is a concern for many athletes. Immunological (increased interleukin-6 [IL-6]) and hormonal (increased cortisol [C], decreased free testosterone [fT]) biomarkers have been analyzed during training to detect OVT development.

Methods: This study determined if resting levels of salivary IL-6, T, and C change during a pre-season resistance training (RT) program in 20 Division I American football players (mean ± SD: age = 19.1 ± 1.1 years; height = 185.4 ± 6.7 cm; mass = 102.0 ± 22.2 kg; body fat = 14.7 ± 7.6%). 1RM squat, bench press and Olympic-style clean, IL-6, C and T were assessed at baseline (WK1), week 4 (WK4), week 6 (WK6) along with psychological status (PS) to determine affective state.

Results: 1RM (bench press: 121.6 ± 36.3 kg vs. 127.4 ± 35.9 kg, squat: 187.2 ± 30.2 kg, 190.9 ± 28.1 kg, clean: 116.8 ± 14.6 kg, vs. 119.2 ± 14.5 kg), IL-6 (1.42 ± 1.77 pg/mL vs. 5.60 ± 12.57 pg/mL) and C (2.57 ± 2.46 nmol/L vs. 5.33 ± 4.94) increased signihcantly from WK1 to WK6 (p < .05), fT decreased signihcantly (417.44 ± 83.63 pmol/Lvs. 341.10 ± 87.79 pmol/L) from WK1 to WK6 (p < .05). PS was minimally affected during the study. Signihcant biomarker changes were detected, but no OVT was induced (i.e. performance improved).

Conclusion: Therefore, directional changes in these biomarkers may not be sufficiently reflective of OVT in RT programs.

作为过度训练生物标志物的静息唾液睾酮、皮质醇和白细胞介素-6 的变化。

背景：过度训练（OVT）是许多运动员关注的问题。已对训练期间的免疫（白细胞介素-6 [IL-6]增加）和激素（皮质醇[C]增加，游离睾酮[fT]减少）生物标志物进行了分析，以检测 OVT 的发展情况：本研究确定了 20 名一级美式足球运动员（平均±标清：年龄 = 19.1 ± 1.1 岁；身高 = 185.4 ± 6.7 厘米；体重 = 102.0 ± 22.2 千克；体脂 = 14.7 ± 7.6%）在季前阻力训练（RT）期间唾液 IL-6、T 和 C 的静息水平是否会发生变化。分别在基线（WK1）、第4周（WK4）和第6周（WK6）对1RM深蹲、卧推和奥林匹克式清扫、IL-6、C和T进行评估，并对心理状态（PS）进行评估，以确定情绪状态：1RM（卧推：121.6 ± 36.3 千克结果：1RM（卧推：121.6 ± 36.3 kg vs. 127.4 ± 35.9 kg，深蹲：187.2 ± 30.2 kg，190.9 ± 28.1 kg，清扫：116.8 ± 14.6 kg，vs. 119.2 ± 14.5 kg）、IL-6（1.42 ± 1.77 pg/mL vs. 5.60 ± 12.57 pg/mL）和 C（2.57 ± 2.46 nmol/L vs. 5.33 ± 4.94）从 WK1 到 WK6 显著增加（p < .05），fT 从 WK1 到 WK6 显著下降（417.44 ± 83.63 pmol/Lvs. 341.10 ± 87.79 pmol/L）（p < .05）。在研究期间，PS 受到的影响很小。检测到显著的生物标志物变化，但没有诱发 OVT（即表现改善）：因此，这些生物标志物的定向变化可能不足以反映 RT 项目中的 OVT。
