The present study set out to ascertain the effects of combined exercises, consisting of resistance training and plyometric exercises at varying degrees of intensity, on biochemical and respiratory parameters in female volleyball players.
The research group consisted of 20 professional female volleyball players who participated in national and international volleyball competitions. Participants were randomly divided into two groups: a control group (n = 10) that performed low-intensity exercises at 30%-50% intensity, and an experimental group (n = 10) that followed a high-intensity exercise programme at 60%-80% intensity. Blood samples and spirometric respiratory function values were collected before and after the 8-week exercise program. The biochemical analyses included the assessment of luteinizing hormone (LH), growth hormone (GH), insulin-like growth factor-1 (IGF-1), and total iron binding capacity. Respiratory function was analysed using forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and forced expiratory flow at mid-expiration (FEF). The data were analysed using the SPSS statistical package.
The results demonstrated a decline in IGF-1, GH, and total iron-binding capacity levels, and an increase in LH levels, in the biochemical parameters of the control group. Additionally, FVC, FEV1, and FEF values exhibited an increase in the control group. Conversely, the experimental group demonstrated a significant increase in LH, GH, IGF-1, and total iron-binding capacity levels. With regard to respiratory parameters, an increase in FEF values was observed, whilst FVC and FEV1 values decreased. The present findings suggest that high-intensity plyometric resistance exercises have more pronounced effects on biochemical responses, but may trigger different adaptation mechanisms in respiratory capacit. The results of the study showed that there was a difference between the control group's GH, IGF-1, FVC, and FEV1 data and the experimental group's GH, IGF-1, FVC, and FEV1 data.
In conclusion, plyometric resistance exercises at varying intensities influence both respiratory and biochemical parameters in female volleyball players. Accordingly, well-planned and individualised plyometric resistance training programmes are thought to enhance both the health and athletic performance of athletes.
本研究旨在确定由不同强度的阻力训练和增强式训练组成的联合训练对女排运动员生化和呼吸参数的影响。
研究组由20名参加国家和国际排球比赛的职业女排运动员组成。参与者被随机分为两组：对照组（n = 10）进行强度为30%-50%的低强度训练，实验组（n = 10）进行强度为60%-80%的高强度训练计划。在为期8周的训练计划前后采集血样和肺活量呼吸功能值。生化分析包括促黄体生成素（LH）、生长激素（GH）、胰岛素样生长因子-1（IGF-1）和总铁结合力的评估。使用用力肺活量（FVC）、一秒用力呼气量（FEV1）和呼气中期用力呼气流量（FEF）分析呼吸功能。数据使用SPSS统计软件包进行分析。
结果显示，对照组生化参数中IGF-1、GH和总铁结合力水平下降，LH水平升高。此外，对照组的FVC、FEV1和FEF值有所增加。相反，实验组的LH、GH、IGF-1和总铁结合力水平显著增加。关于呼吸参数，观察到FEF值增加，而FVC和FEV1值下降。目前的研究结果表明，高强度增强式阻力训练对生化反应有更明显的影响，但可能会在呼吸能力方面引发不同的适应机制。研究结果表明，对照组的GH、IGF-1、FVC和FEV1数据与实验组的GH、IGF-1、FVC和FEV1数据存在差异。
总之，不同强度的增强式阻力训练会影响女排运动员的呼吸和生化参数。因此，精心规划和个性化的增强式阻力训练计划被认为可以提高运动员的健康水平和运动表现。
