This multistudy report examined changes and the doseàresponse relationships between recoveryàstress psychological states, training load(TL), heart rate(HR), heart rate recovery(HRR), and heart rate variability(HRV) while providing evidence for the factorial validity of a short French version of the RecoveryàStress Questionnaire for Athletes(RESTQ-36-R-Sport).Methods: Four hundred and seventy-three university athletes(Study 1), 72 full expert swimmers(Study 2), and 11 national to international swimmers(Study 3) participated in the study. Data were analyzed through confirmatory factor analyses(Study 1), repeated ANOVAs and correlational analyses(Study 2), t tests and correlational analyses(Study 3).Results: Multiple-group confirmatory factor analyses showed that the RESTQ-36-R-Sport scores were partially invariant across gender, type of sport, and practice level(Study 1). A doseàresponse relationship was performed between TL and RESTQ-36-R-Sport scores during an ecological training program(Study 2). Finally, relationships were found between physiological(HRR) and psychological(RESTQ-36-R-Sport) states during an ecological tapering period leading to a national championship(Study 3).Conclusion: As a whole, these findings provided evidence for the usefulness of the short version of the RESTQ-36-R-Sport for regular monitoring to prevent potential maladaptation due to intensive competitive sport practice.展开更多

文摘本研究应用遥测技术连续记录大鼠在无束缚条件下24 h心电信号,并通过心率变异性(H eart ratevariab ility,HRV)频谱分析的方法研究大鼠24 h自主神经活动。大鼠24 h HRV分析结果表明:自主神经活动具有明显昼夜节律,在睡眠期迷走神经活动较活跃,而在清醒期以交感神经活动为主;HRV频谱中低频和高频成分的比值(LF/HF)随着睡眠深度的变化而波动。24 h HRV分析可以获得自主神经系统活动的丰富信息,并有助于研究自主神经系统在生理和病理过程中的调控作用。
