摘要
目的:本研究调查了为期 10 周的准备期训练对精英手球运动员生物标志物和跳跃表现的影响,以及从准备期开始(PRE)到准备期结束(POST)期间生物标志物、负荷和跳跃表现变化的关联。研究方法招募了 17 名参加斯洛文尼亚第一届男子联赛的精英手球运动员。每周报告一次训练、比赛和学习负担,同时在准备期和结束期评估生物标志物和跳跃表现。结果显示在运动后观察到游离睾酮水平下降(大效应量[ES] = -1.69, p p = .004);而与运动前相比,单腿侧向跳跃测试[SLLH] (大效应量[ES] = .85, p = .007)和单腿三跳测试[SLTH] (大效应量[ES] = 1.05, p = .002)的表现更好。此外,FTCR 的变化与皮质醇(高 r = -.751,p = .001)、SLLH(中度 r = -.603,p = .022)和 SLTH(中度 r = -.643,p = .013)的变化相关,而游离睾酮的变化与 SLTH 相关(中度 r = -.645,p = .013)。结论高强度的训练和饱和的比赛日程会导致合成代谢/代谢激素比率紊乱,通过 FTCR 的下降可以观察到这一点,这可能预示着最佳状态或早期衰竭。与单腿跳跃测试相比,SLLH 和 SLTH 似乎对生物标志物的变化更为敏感。体育专业人士可以利用这些结果对运动员的健康和表现进行个性化监测,特别是作为相应调整训练负荷的辅助工具,以防止表现下降和潜在的伤病事件。
Anabolic/Catabolic Hormone Imbalance but Still Jumping Further? Negative Association of Free Testosterone With Jumping Performance in Elite Handball Players Following a Preparatory Period.
Purpose: The present study investigated the effects of a 10-week preparatory training period on biomarkers and jumping performance and associations of changes in biomarkers, load, and jumping performance from the beginning (PRE) to the end of the preparatory period (POST) in elite handball players. Methods: Seventeen elite handball players competing in the first Slovenian men's League were recruited. Training, competition and academic loads were reported weekly, while biomarkers and jumping performance were assessed at PRE and POST. Results: At POST, decreased levels of free testosterone (large effect size [ES] = -1.69, p < .001) and free testosterone to cortisol ratio [FTCR] (large ES = -.95, p = .004) were observed; whereas, better performance on the single leg lateral hop test [SLLH] (large ES = .85, p = .007) and single leg triple hop test [SLTH] (large ES = 1.05, p = .002) were observed compared to PRE. Furthermore, changes in FTCR correlated with changes in cortisol (high r = -.751, p = .001), SLLH (moderate r = -.603, p = .022), and SLTH (moderate r = -.643, p = .013), while changes in free testosterone correlated with SLTH (moderate r = -.645, p = .013). Conclusions: High intensity trainings with a saturated competition schedule can result in disturbed anabolic/catabolic hormone ratio observed through FTCR decrease, which could indicate either an optimal state or early exhaustiveness. It seems that SLLH and SLTH are more sensitive to changes in biomarkers than a single leg hop test. Sport professionals may use the results for individualized monitoring of an athlete's health and performance, specifically, as an aid for adjusting training loads accordingly to prevent performance declines and potential injury/illness events.
