心率变异性（HRV）指导训练已被证明能有效提升运动表现。HRV 指导训练的核心思路是：只有当 HRV 分数处于正常范围之内或之上时，才安排中等及以上强度的训练课；当 HRV 分数低于正常范围时，则安排低强度训练或休息日。这里的「正常范围」是按个体定义的，需要经过若干天的测量才能建立。在 Kubios HRV 的恢复度指数中，这一正常范围是基于过去 3 个月的数据确定的。 Heart rate variability (HRV) guided training has been proven effective in improving athletic performance. The key to HRV-guided training is to perform moderate and higher intensity workouts only when the HRV score is within or above the normal range. Lower intensity workouts or rest days are prescribed when the HRV score is below the normal range. The normal range is defined on an individual basis and is established over several days. In the Kubios HRV Readiness index, the normal range is established over the past 3 months.
运动员的心率变异性监测Heart rate variability monitoring for athletes
心率变异性（HRV）反映的是相邻心跳间隔的波动，能够揭示心脏自主神经功能和整体生理状态。与非运动员相比，耐力运动员通常表现出更优的心脏自主神经功能，具体特征是静息心率更低、静息 HRV 更高。静息 HRV 的逐步升高，与有氧能力和运动表现的改善相关。 Heart rate variability (HRV) reflects fluctuations in the intervals between consecutive heartbeats, providing insight into cardiac autonomic function and overall physiological state. Endurance athletes typically demonstrate superior cardiac autonomic function compared to non-athletes, characterized by lower resting heart rates and greater resting HRV. Gradual increases in resting HRV have been linked to improved aerobic fitness and performance.
由于监测工具越来越容易获得，HRV 指标的可用性与使用率都在上升。运动员、教练和运动医学团队普遍会采集 HRV 数据，其中最常被推荐的做法是每天早晨进行静息 HRV 测量。为运动员的生理状态监测选择合适的 HRV 参数至关重要。RMSSD 是最常用的参数，因为它反映心脏迷走神经调控，不受呼吸频率影响（不像 HF 功率那样），而且计算简单。但 RMSSD 有一个局限：由于「HRV 饱和」现象，有时在静息心率很低的情况下反而会观察到 HRV 下降。使用把静息心率一并纳入考量的 PNS 指数，可以规避这一局限。 The availability and use of HRV metrics have increased due to the ease of access to monitoring tools. Athletes, coaches, and sports medicine staff commonly collect HRV data, with daily resting HRV measurements taken in the morning often recommended. Selecting the appropriate HRV parameter for monitoring athletes' physiological state is crucial. RMSSD is the most commonly used parameter because it reflects cardiac vagal regulation, is not affected by respiratory rate (unlike HF power), and is simple to calculate. However, RMSSD has a limitation, where reduced HRV can sometimes be observed despite a low resting HR due to HRV saturation. This limitation can be addressed by using the PNS index, which accounts for resting heart rate.
训练如何影响 HRVHow training affects HRV
训练对静息 HRV 的影响因人而异，取决于训练状态、心肺适能、年龄和性别等因素。规律的有氧训练通常会提高运动员的 HRV。但训练时长的增加会抬高整体训练负荷，并在急性层面降低当日的 HRV。而训练强度则会在运动当时或次日影响 HRV 分数。 The impact of training on resting HRV is individual and influenced by factors such as training status, cardiorespiratory fitness, age, and sex. Regular aerobic training typically increases HRV in athletes. However, increased exercise duration can elevate the overall training load and acutely decrease daily HRV. Exercise intensity, on the other hand, impacts HRV scores either immediately or the day after exercise.
通过每日静息 HRV 测量来评估心脏自主神经功能，是一种无创的手段，可以反映机体对耐力运动的急性与慢性适应。在短期内（运动后 48 小时内），HRV 回归基线的过程，与体温调节、代谢、血流动力学和体液平衡等被体力消耗打乱的过程的恢复是同步的。而长期看，静息 HRV 水平更高、更稳定的曲线，在久坐人群、中等训练水平人群、高水平运动员以及临床人群中，都与干预后更大的体能改善相关。 Cardiac-autonomic functioning, assessed via daily resting HRV measurements, serves as a non-invasive marker of acute and chronic adaptation to endurance exercise. In the short term (within 48 hours after exercise), HRV recovery to baseline coincides with the restoration of thermoregulatory, metabolic, hemodynamic, and fluid-balance processes disrupted by physical exertion. Long-term HRV profiles reflecting higher and/or more stable resting values are associated with greater improvements in post-intervention fitness outcomes among sedentary, moderately-trained, highly-trained, and clinical populations.
HRV 指导训练的执行协议HRV-guided training protocol
HRV 指导训练协议的做法，是根据每日心率变异性读数来调整训练强度，以优化表现与恢复。当 HRV 分数处于运动员个人正常范围之内或之上时，推荐进行中到高强度的训练；反之，当 HRV 分数低于正常范围时，则建议安排低强度活动或休息日。这种个性化的方式有助于平衡训练压力与恢复，降低过度训练的风险，并整体提升运动表现。Kubios HRV App 提供了经过验证的每日 HRV 测量手段，运动员可以免费使用它来评估每日恢复状态，从而有效地执行 HRV 指导训练。 HRV-guided training protocols involve tailoring workout intensity based on daily heart rate variability readings to optimize performance and recovery. When the HRV score is within or above the athlete's normal range, moderate to high-intensity workouts are recommended. Conversely, when the HRV score is below the normal range, lower intensity activities or rest days are advised. This personalized approach helps balance training stress and recovery, minimizing the risk of overtraining, and enhancing overall athletic performance. The Kubios HRV app provides validated means for daily HRV measurement and can be used free of charge by athletes to assess daily recovery status, ensuring effective HRV-guided training.
基本原则是：每当每日 HRV 分数下降时就降低训练强度，同时不允许连续超过两次的高强度训练，也不允许连续超过两天的休息。 The basic idea is to lower the training intensity whenever the daily HRV score decreases and not to allow more than two consecutive high-intensity exercises or rest days.
HRV 指导训练的有效性Effectiveness of HRV-guided training
已有多项研究将 HRV 指导训练与预设训练计划进行了对照验证。这些研究表明，「HRV 指导训练是有效的，它与次最大强度表现的改善相关，整体表现与体能水平相当或更好，且非应答者（练了没效果的人）更少。」此外，HRV 指导训练所带来的收益，通常是在中等和/或高强度训练总量减少的情况下取得的。 HRV-guided training has been validated against predefined training in several studies. These studies have shown that "HRV-guided training is effective, associated with improved submaximal performance, better or similar overall performance and physical fitness, and fewer non-responders." Additionally, the benefits of HRV-guided training are typically achieved with a reduced amount of moderate and/or high-intensity training.
总结来说，HRV 指导训练是一种门槛低、个体化的运动处方策略，在维持和提升运动表现方面可能比预设训练计划更有效，且出现负面反应的可能性更低。每日 HRV 监测让运动员能够逐日调整训练，并观察自身生理状态的变化。借助 Kubios HRV 团队恢复度看板，教练也可以利用 HRV 数据为运动员定制训练方案。平均 HRV 的逐步上升，对应着整体生理表现、有氧能力、机能状态、训练准备度和恢复能力的提升；反之，HRV 的持续下降则与适应不良状态相关，包括疾病、非功能性过度训练，以及最坏情况下的过度训练综合征。 In summary, HRV-guided training is an accessible and individualized exercise prescription strategy that may be more effective than predefined training for maintaining and improving performance, with a lower likelihood of negative responses. Daily monitoring of HRV allows athletes to adjust their training day-by-day and observe changes in their physiological state. With the Kubios HRV Team Readiness dashboard, coaches can also leverage HRV data to tailor training programs for their athletes. Gradual increases in average HRV correspond with improved overall physiological performance, aerobic fitness, high functional state, readiness to train, and recovery ability. Conversely, decreasing HRV has been associated with maladaptive states, including illness, non-functional overtraining, and, in the worst case, overtraining.
