The use of Heart rate variability (HRV) has become increasingly popular as a non-invasive methodology that provides an indirect insight into the autonomic nervous system. HRV can be utilized as a diagnostic tool in detection of autonomic nervous system impairment and sympatho-vagal imbalance. HRV technology is employed to monitor the internal response of athletes to workload and identify athletes’s psychophysical stress to predict and therefore prevent injuries. Objective: The objective of the investigation is to establish whether the use of Polar H10 sensor heart rate monitors worn by athletes in a sitting position (inclination 60 degrees) during periods characterized by stress can provide a valid and non-invasive method to assess the psychophysiological state during sports competition and school exams. Method and Statistics: In the study, the HRV of 12 basketball students athletes and 4 students non-athletes was analyzed as a control group. The autonomic nervous system activity was assessed based on heart variability parameters (HRV): SDNN, rMSSD, LF, HF, and LF/HF. The measurements were made after establishing the baseline at rest, during the training phase (CT), competition phase (CC) and during the acute phase of stressors due to school exams coinciding with the competitive season (CC + E). Results: Compared to the respective values prior to the stress of the competitions and exams, a significant decrease in HRV indices was found: SDNN (P Conclusions: The analysis and examination of the data on the sample of the student population also showed a statistically significant correlation between decreased cardiac variability and injuries or indisposition to physical exertion.展开更多
为评价有氧、无氧耐力训练对自主神经功能的影响,提供健全、合理体育锻炼方案的理论依据,我们将41名健康男性青年,随机分为有氧耐力组和无氧耐力组,进行连续8周训练。分别于训练前、训练4周末、训练8周末进行5 m in短程心率变异性(HRV)...为评价有氧、无氧耐力训练对自主神经功能的影响,提供健全、合理体育锻炼方案的理论依据,我们将41名健康男性青年,随机分为有氧耐力组和无氧耐力组,进行连续8周训练。分别于训练前、训练4周末、训练8周末进行5 m in短程心率变异性(HRV)频域、时域法分析。结果显示,与训练前比较,有氧耐力组迷走神经活动增强(HF、HFnu、RM SSD、PNN 50,P值均<0.05),交感神经活动呈减弱趋势(LFnu),自主神经平衡表现为趋向迷走神经占优势(LF/HF),HRV增大;无氧耐力组自主神经调节功能相对较稳定。本研究表明,有氧、无氧耐力训练对自主神经调节能力的影响取决于训练的负荷强度,与有氧训练相似,严格控制的适当强度的无氧耐力训练也可能有利于增强人体对环境的适应能力。展开更多
