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.

过度训练(OVT)是许多运动员关注的问题。免疫(白细胞介素-6 [IL-6]升高)和激素(皮质醇[C]升高，游离睾酮[fT]降低)生物标志物在训练过程中进行分析，以检测OVT的发展。方法本研究测定了20名美国甲级橄榄球运动员(平均±SD:年龄= 19.1±1.1岁;身高= 185.4±6.7 cm;质量= 102.0±22.2 kg;体脂= 14.7±7.6%)。在基线(WK1)、第4周(WK4)、第6周(WK6)以及心理状态(PS)时评估IL-6、C和T，以确定情感状态。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，清洁:116.8±14.6 kg，分别比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显著升高(p < 0.05)， fT显著降低(417.44±83.63 pmol/Lvs)。(341.10±87.79 pmol/L)，差异有统计学意义(p < 0.05)。PS在研究期间受到的影响最小。检测到显著的生物标志物变化，但没有引起OVT(即性能提高)。因此，这些生物标志物的方向性变化可能不能充分反映RT计划中的OVT。
