In the realm of headache disorders, migraines stand as a formidable challenge, often disrupting the lives of millions with their debilitating intensity and frequency. Among the myriad therapeutic approaches, biofeedback for migraines has emerged as a promising avenue, gaining increasing recognition. This innovative technique harnesses the body’s inherent ability to regulate physiological processes, offering a non-invasive and empowering path to migraine management.

As we explore biofeedback modalities designed explicitly for migraines, we explore the intricate connection between the mind and body. From traditional methods to the latest cutting-edge technologies, the biofeedback interventions landscape is diverse and captivating. In this article, we aim to illuminate the various biofeedback modalities, their underlying mechanisms, and, most importantly, their effectiveness in mitigating the impact of migraines on individuals facing this neurological challenge.

Understanding Migraines and Triggers

Migraines are not just headaches. They are complex neurological events that can significantly impact daily life. To effectively manage migraines with biofeedback, it’s essential to understand their nature and the triggers that can set them off.

Migraines are intense, throbbing pain, usually on one side of the head. Accompanying symptoms often include nausea, sensitivity to light and sound, and sometimes visual disturbances or tingling sensations. To read more about the symptoms of migraine – go here.

Identifying triggers is crucial for successful migraine management. Triggers can vary from person to person, but common ones include:

Role of Stress:

Stress is a common trigger for migraines, with heightened stress levels leading to the release of neurotransmitters and neuropeptides that can activate pain pathways in the brain. Stress can lead to muscle tension and changes in blood flow, contributing to migraines. Tense muscles, particularly on the face, neck, and shoulders, can contribute to migraines. Increased muscle tension may affect blood flow and activate pain-sensitive nerves (muscular tension trigger). Changes in blood flow and vascular dilation are associated with migraines. Fluctuations in blood vessel caliber can trigger pain signals in the brain (vascular trigger). Intense emotions, whether positive or negative, can trigger migraines. Emotional arousal activates the sympathetic nervous system, influencing pain pathways (emotional arousal trigger).

Hormonal Changes:

Fluctuations in estrogen levels, often experienced by women during menstruation, pregnancy, or menopause, can trigger migraines.

Dietary Factors:

Certain foods and beverages, such as chocolate, caffeine, and aged cheeses, may act as triggers. Tyramine is a compound in aged cheeses, processed meats, and certain fermented foods. It can lead to the release of neurotransmitters like norepinephrine, potentially causing blood vessels to constrict and dilate, triggering migraines. Nitrites and nitrates, often used as preservatives in processed meats (cured meats, hot dogs, and bacon), can lead to the dilation of blood vessels. This dilation may contribute to migraine onset. While caffeine (coffee, tea, chocolate, and certain medications) itself can be a migraine trigger for some, sudden withdrawal from regular caffeine consumption can also lead to headaches. 

Histamine, a compound involved in allergic reactions, can be released in response to certain foods. Elevated histamine levels may contribute to migraines.

Environmental Factors:

Bright lights, strong smells, or changes in weather patterns can provoke migraines. Migraine sufferers often experience heightened sensitivity to light, a condition known as photophobia. Exposure to bright lights can stimulate the visual pathways and trigger abnormal responses in the brain, potentially leading to migraine attacks. Bright lights can overstimulate the optic nerve and related structures, leading to increased cortical excitability and the release of neurotransmitters associated with migraine, such as serotonin. 

Osmophobia, or sensitivity to odors, is a common symptom in migraine-prone individuals. Strong smells can activate the trigeminal nerve, which plays a crucial role in migraine development. Moreover, these smells may trigger the release of neuropeptides that help modulate pain sensation. In addition to detecting chemical stimuli, the trigeminal nerve’s activation can also lead to the release of substances that cause blood vessel dilation and inflammation. As a result, this process contributes to migraine pain.

Weather-related triggers, such as changes in barometric pressure, temperature, or humidity, can impact the nervous system and potentially contribute to migraine onset. Fluctuations in atmospheric pressure can influence blood vessel tone and alter the balance of neurotransmitters, creating conditions conducive to migraine attacks in susceptible individuals.

Sleep Disturbances:

Irregular sleep patterns or lack of sleep can contribute. The body’s internal biological clock, or circadian rhythm, regulates various physiological processes, including sleep-wake cycles. Disruptions in this rhythm, such as irregular sleep patterns or insufficient sleep, can affect the balance of neurotransmitters (like serotonin and melatonin, which play roles in sleep regulation and are implicated in migraine pathophysiology) and hormones, potentially contributing to migraine susceptibility.

Dehydration:

Insufficient water intake can lead to dehydration, triggering migraines.

Understanding migraines and their triggers lays the foundation for effective biofeedback intervention. These insights empower individuals to tailor their biofeedback strategies to address specific triggers and achieve meaningful relief.

Biofeedback for Migraine: A Growing Paradigm in Management

Migraines can be debilitating, affecting millions worldwide. In the pursuit of practical, non-pharmacological solutions, biofeedback for migraines emerges as a promising ally. As the landscape of migraine management evolves, integrating biofeedback techniques represents a significant frontier.

Biofeedback, as a non-invasive therapeutic approach, empowers individuals to gain conscious control over physiological processes often linked to migraine triggers. This technique involves real-time monitoring and presentation of physiological information, which allows individuals to develop awareness and control over their bodily functions. By providing immediate feedback, biofeedback will enable individuals to make conscious adjustments to physiological processes that may contribute to migraines. Consequently, this approach not only enhances self-awareness but also supports proactive management of migraine-related symptoms.

Biofeedback for migraines aims to address migraine triggers by helping individuals become more aware of and gain control over the physiological responses linked to migraines. By recognizing how stress, muscle tension, and other contributing factors play a role in triggering migraines, individuals can then use biofeedback techniques to reduce and manage these triggers effectively.

Understanding migraines and their triggers lays the foundation for effective biofeedback intervention. These insights empower individuals to tailor their biofeedback strategies to address specific triggers and achieve meaningful relief.

Electromyographic (EMG) Biofeedback for Migraines

EMG biofeedback focuses on monitoring and regulating muscle tension, a common contributor to migraines. Surface electrodes are strategically placed on specific muscles, such as the forehead (m. Frontalis, which tightens when you frown or feel stressed), the face (m. Masseter, which tightens when you clench your jaw due to frustration, anger, or worry), and the neck/shoulders (m. Trapezius, which tightens in response to alarm, anxiety, or other physical stressors). These electrodes provide real-time feedback on muscle activity. By gaining awareness of muscle tension through this feedback, individuals can learn to relax these muscles, thereby reducing tension and potentially preventing migraines.

EMG biofeedback aims to break the cycle of muscular tension and migraine exacerbation. Individuals can decrease the frequency and intensity of tension-related migraines by enhancing control over muscle activity.

According to literature data, the statistical evidence strongly supports EMG biofeedback (EMG biofeedback showed a moderate effect in reducing both the frequency and intensity of migraines) as an effective intervention for migraine management. By addressing muscle tension, which is a common contributor to migraines, individuals can gain better control over their physiological processes, potentially reducing both the frequency and intensity of headache episodes. Among the various biofeedback modalities, EMG biofeedback emerges as a valuable and targeted tool, offering individuals a personalized approach to preventing migraines.

• Explanation: Exertional headaches triggered by physical activity may be influenced by autonomic responses and vascular changes. HRV biofeedback addresses autonomic balance, while temperature biofeedback can impact vascular function. Together, these modalities offer a multifaceted approach to managing exertional headaches by targeting both autonomic and vascular components.

Psychogenic Headaches:

• Biofeedback Modality: GSR (Galvanic Skin Response) Biofeedback
• Explanation: Psychogenic headaches with a strong emotional component may benefit from GSR biofeedback, allowing individuals to manage emotional arousal and potentially reduce the impact of psychological triggers.

Chronic Paroxysmal Hemicrania (CPH):

• Biofeedback Modality: EMG (Electromyographic) Biofeedback
• Explanation: CPH, a rare headache disorder, involves severe, short-lived headaches. EMG biofeedback can help address muscle tension, potentially reducing the intensity and frequency of headaches.

Post-Concussion Headaches:

• Biofeedback Modality: Comprehensive Approach (Combining HRV, EMG, GSR)
• Explanation: Post-concussion headaches can be triggered by multiple factors, including stress, muscle tension, and emotional factors. A comprehensive biofeedback approach, which addresses these various components, may help manage post-concussion headaches more effectively.

Tension-Type Headaches:

• Biofeedback Modality: EMG (Electromyographic) Biofeedback
• Explanation: Tension-type headaches, characterized by a persistent band-like pressure, often involve muscle tension. EMG biofeedback specifically targets the recognition and control of muscle tension, potentially reducing both the frequency and severity of tension-type headaches.

Chronic Tension-Type Headaches:

• Biofeedback Modality: Comprehensive Approach (Combining HRV, EMG, GSR)
• Explanation: Chronic tension-type headaches may benefit from a comprehensive biofeedback approach, addressing stress, muscle tension, and emotional factors to provide holistic headache management.

Photophobia-Triggered Migraines:

• Biofeedback Modality: Visual Biofeedback (Notable for Neurofeedback/EEG)
• Explanation: Migraines triggered by sensitivity to light (photophobia) may find relief through visual biofeedback, particularly neurofeedback (EEG biofeedback), which can assist in regulating brainwave patterns associated with sensitivity to light.

The effectiveness of biofeedback modalities can vary among individuals, and a personalized approach, possibly combining different modalities, may be most beneficial for comprehensive migraine management. Combining different biofeedback modalities, such as HRV for stress and EMG for muscle tension, may offer a more comprehensive approach to migraine management. This approach recognizes the multifaceted nature of migraines and addresses multiple contributing factors simultaneously. For example, it is adequate to combine HRV and GSR Biofeedback in stress-related migraines. Before determining the optimal combination, it is crucial to identify the key contributors to an individual’s migraines. Stress, muscle tension, autonomic dysregulation, and physiological imbalances are common factors.

HRV in sport performance

Heart Rate Variability in Athletes

Heart rate variability in athletes has gained significant attention as a crucial indicator of physical fitness and recovery. This metric reflects the body’s ability to adapt to stress and is particularly valuable for monitoring the training and performance of athletes. Analyzing the HRV of athletes, coaches, and trainers can gain insights into an athlete’s autonomic nervous system activity, recovery status, and overall well-being. Understanding heart rate variability (HRV) helps optimize training loads and plays a vital role in preventing overtraining and injuries. In this article, we will explore the importance of HRV in athletes, its impact on performance, and how it can be effectively utilized to enhance athletic outcomes.

Athletes' Pursuit of Improvement and the Role of HRV

As an athlete, you always look for that 1% improvement in every aspect of your game. However, as elite athletes improve and the margin for improvement narrows, achieving a 1% improvement becomes harder. With that in mind, athletes are conditioned to revert to the “train harder” mentality to grab that 1%. This mentality doesn’t always work because, much too often, overtraining and injuries occur. If you want to ensure your body is peaking at the right moments, having insight into HRV becomes that coveted 1% of all athletes are looking for.

Heart rate variability (HRV) represents variations between consecutive heartbeats (beat-to-beat or R-R interval) over time. This beat-to-beat variation in heart rhythm is considered normal and even desirable. When variations between consecutive heartbeats disappear, autonomic dysfunction is often the cause. This dysfunction can link to neurological, cardiovascular, and psychiatric diseases. Many studies show that higher heart rhythm variability relates to reduced mortality, improved quality of life, and enhanced physical fitness. (Learn more about Heart Rate Variability here).

Physiological Background and HRV’s Impact on Athletes’ Performance

The physiological background of HRV is complex and affected by circulating hormones, baroreceptors, chemoreceptors, and muscle afferents. An important factor influencing HRV is respiratory sinus arrhythmia – the natural variation in heart rate (HR) during breathingDuring inspiration, HR increases, whereas during expiration, HR decreases. The autonomic nervous system (ANS), through sympathetic (SNS) and parasympathetic (PNS) pathways, regulates the function of internal organs and the cardiovascular system. During training or competition, sympathetic activity (“fight or flight”) increases an athlete’s cardiac contractility, heart rate, breathing, and muscle tension.

In contrast, parasympathetic (vagal) stimulation (“rest and digest”) reduces an athlete’s heart rate, relaxes muscles, and allows for digestion. Any source of stress (psychological, physical, or illness) will provoke disturbance in the ANS and, consequently, in HRV. The long-term presence of an imbalance between sympathetic and parasympathetic tones can impair athletes’ performance.

HRV data offers a unique view into nervous system activity. This insight helps athletes find the right balance between training and recovery.

Heart rate variability in athletes

HEART RATE VARIABILITY IN ATHLETES DURING AND AFTER EXERCISE (INDICATORS OF STRESS/TRAINING LOAD)

During exercise, HRV is reduced (shorter R-R intervals), and heart rate is increased due to augmented SNS and attenuated PNS activity. Not only are the intervals between R-R peaks shorter, but they also become more uniform (reduced R-R variability).

The relationship between sympathetic and parasympathetic activity during exercise depends directly on training intensity. During physical activity, sympathetic nerves can increase cardiac output to 2 to 3 times the resting value.

Caution should be taken when interpreting HRV analysis during exercise. When exercise intensity exceeds 90% of VO2 max, breathing frequency rises. This increase boosts vagal contribution, or PNS activity, due purely to the heart’s mechanical properties rather than any neural input from the ANS. As a result, PNS activity, driven by faster respiration, can mask actual SNS activity at these higher intensities. To ensure accurate results, the athlete should maintain a stable respiration rate as much as possible during an incremental test to exhaustion.

TRAINING LOAD

The distribution of training loads is a fundamental component of periodization. The elements that comprise the training load are training volume and intensity. The interplay between these two elements will define the total training load. Higher training loads will cause greater ANS disturbance and sympathovagal imbalance. Post-exercise HRV analysis appears to be a valuable indicator for evaluating variations in performance level and can indirectly reflect training loads. There is evidence that HRV parameters are highly correlated with the intensity and volume of exercise and are inversely related to the training load level.

RECOVERY AND HEART RATE VARIABILITY IN ATHLETES PERFORMANCE

Understanding Stress, Adaptation, and Recovery in Training

On the assumption that physical activity causes stress (a stimulus), the body will respond with a stress reaction on different physiological levels. In addition to a stress reaction, adaptation processes occur during recovery. Suppose the magnitude of the stress stimulus (training load) is high enough (overload principle) to evoke a reaction in the body. In that case, the response will be proportional to the stress level, and, as a result, greater training effects will be accomplished (adaptation).

To reach higher performance levels in sports, it is essential to understand that well-designed and integrated rest periods are crucial. Recovery after training is considered an integral part of the training methodology. Performance will not improve if there is a lack of optimal recovery. Problems occur when the demands are so frequent that the body cannot adapt. This means the body will continuously be under sympathetic domination during rest and activity.

Most athletes and sports science personnel understand the importance of recovery after exercise, defined as the return of body homeostasis after training to pre-training or near pre-training levels.

The Role of Recovery and Its Impact on Performance

Recovery involves getting adequate rest between training sessions/competitions to allow the body to repair and strengthen itself in preparation for the subsequent bout. Optimal athletic performance is supported when recovery to pre-training or near pre-training levels is permitted. If recovery is insufficient, hindrance of physiological adaptation and reduced athletic performance should be expected. Recovery plays a major role in minimizing the harmful effects of training (fatigue) while retaining the positive impact (improved fitness/strength/performance).

Without monitoring recovery after exercise, fatigue can build up and become excessive before competition. This buildup reduces athletic performance and may even lead to overtraining syndrome. The overtraining syndrome occurs when training stress is too high, and recovery is insufficient, causing fatigue and decreased performance.

Heart rate variability in athletes performance: Train-Recover-Perform

Every training session stresses the body and disturbs homeostasis and ANS modulation. These changes in ANS activity manifest as increased sympathetic activity or decreased parasympathetic activity, which reflects in HRV parameters. One crucial aspect of recovery is sleep, during which parasympathetic activity should dominate. However, an optimal recovery state typically features parasympathetic (vagal) predominance of the ANS, regardless of the time of day.

HRV as a Noninvasive Tool for Monitoring Recovery

Various parameters can be used to measure post-exercise recovery (VO2 max, creatine kinase, C-reactive protein, plasma cortisol, blood leukocyte, myeloperoxidase protein level, and glutathione status). However, these methods are mostly invasive, time-consuming, and expensive for everyday use. Accordingly, the importance of a noninvasive, easy, and affordable method to evaluate recovery is obvious. Thus, HRV technology is increasingly used to evaluate the status and level of recovery.

Long-term high-intensity training sessions gradually decrease the parasympathetic component of HRV, which increases during the rest of the period. The sympathetic component demonstrates the opposite tendency.

Reactivating HRV’s parasympathetic activity to pre-exercise levels as quickly as possible significantly improves athletes’ recovery. When HRV parameters cannot return to pre-exercise or optimal levels within a reasonable time, this indicates a chronic disturbance in ANS activity. Such a disturbance can lead to overtraining.

Today, HRV-based devices and software assist in athletes’ recovery analysis, providing easily interpretable data to trainers and athletes. The most common procedure to evaluate recovery level involves overnight measurement (nocturnal) of HRV, although systems that can assess a quick recovery index (5-minute measurement) are also available.

THE USE OF HEART RATE VARIABILITY IN ATHLETES: OVERTRAINING AND HOW AVOID IT?

Sometimes, the line between optimal performance level and overtraining is skinny.

Overtraining syndrome (OTS) results from a long-term imbalance between stress (internal and external) and recovery periods. A large body of evidence implies that overtraining syndrome causes significant cardiac autonomic imbalance between the two ANS pathways (sympathetic and parasympathetic).

The literature contains conflicting results about ANS modulation in overtrained athletes. Some studies report a predominance of sympathetic and parasympathetic autonomic tone during an overtrained period. The description of different types of overtraining might explain these disputed results.

Two types of OTS have been reported: sympathetic and parasympathetic overtraining, each with specific physiological characteristics.

Sympathetic tone

Insomnia

Irritability

Tachycardia

Agitation

Hypertension

Restlessness

Parasympathetic tone

 

Fatigue

Bradycardia

Depression

Loss of motivation

 

The early stages of performance impairment feature sympathetic domination of the ANS at rest. This condition is often called an “overreaching state” or “short-term overtraining.” This means that the disturbance of homeostasis was not high and long enough to provoke a chronic overtraining state. Therefore, the time needed to fully recover all physiological systems typically encompasses several days to weeks.

Sports that require higher exercise intensity generally show increased sympathetic tone. If the overreaching state (sympathetic autonomic tone domination) continues for longer, OTS and domination of parasympathetic autonomic tone will develop. Parasympathetic OTS dominates in sports characterized by high training volume.

LIMITATIONS, IMPROVEMENTS AND FUTURE PERSPECTIVES OF ANALYSIS OF HEART RATE VARIABILITY IN ATHLETES PERFORMANCE

Analysis of heart rate variability in athletes’ performance has become a widely accepted method for noninvasive evaluation of ANS modulation during and after exercise. To overcome the aforementioned disadvantages, the recording signal must contain a minimum of 5 minutes of HRV fluctuation to get reliable results.

In the last 5 years, the number of devices and software programs/apps using HRV technology has increased exponentially. The current trend in software engineering is to make all wireless sensors for capturing and transmitting HRV data compatible with smartphones. Hardware and software engineers are continuously improving the accuracy of sensors that record and receive HRV signals (heart rate belts, wireless technologies, and protocols) and HRV analysis techniques (software, mathematical models). This provides the trainer and athlete with quick and easy analysis of HRV data during and after a training workout (training load, recovery, and overtraining).

THE GOAL OF MONITORING OF HRV IN ATHLETES PERFORMANCE

HRV provides an excellent objective status of the autonomic nervous system. The primary goal is reducing injuries, decreasing overreaching, improving player health, increasing adaptation, and learning more about training. However, winning requires that talent is available and optimized in performance, not just uninjured. The essence of monitoring heart rate variability in athletes is to drive a routine and accountability process for winning. The data collected from HRV can guide athletes like a compass to a training program blueprint, but only if the commitment exists with everyone. Winning requires talent and preparation, and while only a few can be on top of the mountain, HRV can increase those odds if appropriately used.

MEASUREMENT PROTOCOL

Metrics

  • RMSSD is the most commonly used and trusted metric. It is a clear marker of parasympathetic activity (recovery). RMSSD is linked to performance changes, fatigue states, overreaching, and overtraining. The return of RMSSD to baseline after exercise has been related to the clearance of plasma catecholamine, lactate, and other metabolic byproducts, in addition to restoring fluid balance and body temperature.
    Therefore, RMSSD serves as a global marker of homeostasis, reflecting various aspects of recovery. This marker may explain why planning intense training when HRV is at or above baseline can help improve endurance performance.
  • Duration: 60 seconds to 2 minutes in the morning is the ideal measurement protocol for reliability and practical applicability in team settings. Night measurements are also a valid method.
  • Frequency: To establish a valid baseline, at least three days per week are required. More measurements can be beneficial, up to five ideally. If compliance is an issue, prioritize the three days in the middle of the week, far from matches, to avoid residual fatigue.

Data analysis: The most important parameters to examine are baseline HRV and the coefficient of variation (CV).

  • HRV baseline: computed as the average HRV over a week (or 3-5 days if daily measurements are challenging to obtain). An athlete’s average values should be analyzed. Typical values are a statistical way to represent historical data collected in the previous 30 to 60 days. This should give us insights into where we expect the HRV baseline to be, provided no significant stressors are present. In case of such significant stressors or issues in responding to training or lifestyle stressors, the baseline will deviate from the expected typical values.
  • CV: Coefficient of Variation, or the amount of day-to-day variability in HRV.

Insights

Pre-session: load can be adjusted based on individual responses as shown in baseline HRV and CV. In particular:

  • Athletes showing a reduced HRV and increased CV most likely struggle with the load and might benefit from reduced load or other recovery strategies (sleep, diet, yoga, or different ways to minimize non-training-related stress, for example).
  • Athletes showing a stable or increasing HRV are likely coping well with the increased load.
  • Athletes showing a reduced CV likely cope well with the increased load unless their baseline HRV reduces or goes below average. In this case, the reduced CV might highlight an inability to respond to training.

The same patterns throughout the session can help you understand individual responses to changes in training load. Use HRV as a continuous feedback loop rather than a target to optimize toward a specific value. Staff working with athletes and physiological measures should prioritize baseline and CV changes to determine individual responses and adaptations.

ESENSE PULSE WEARABLE ECG MONITOR

Heart Rate Variability (HRV) refers to the variable time between individual heartbeats. An ECG can accurately measure HRV. A basic heart rate monitor can also provide this data, but the HRV will not be as accurate.
Only elite athletes and their coaches had access to HRV data in the past because devices that measure ECG were costly and difficult to wear.

In the last five years, innovations in wireless technology have significantly increased the number of devices on the market that use HRV indices to control and manage athletes’ training processes. Now, with accessible, wearable, and user-friendly technology like the eSense Pulse wearable ECG monitor, everyone from professional athletes to weekend warriors can use HRV data to enhance their training.

TARGET HEART RATE

While using eSense Pulse, the eSense App displays the current heart rate and the target heart rate during recording in the overview area. The target heart rate can be adjusted at any time in the settings of your eSense App. You can either set it directly or as a percentage of the predicted maximum heart rate. By default, the target heart rate value is 85% of the expected maximum HR.

The predicted maximum heart rate is calculated using the following formula: Predicted Maximum Heart Rate = (220—your age in years). Normally, you should maintain your heart rate below your target level (85% of a predicted maximum heart rate, based on your age and medical conditions).

HRV focuses on the distance between peaks. In the eSense App, the SDNN (Standard deviation of all NN intervals) and RMSDD (Root Mean Square of the Successive Differences) is one of a few time-domain tools used to assess heart rate variability, the successive differences being neighboring RR intervals) values relate to the time interval between peaks, but RMSDD best shows parasympathetic or “rest and digest” activity. Accurate RMSDD measurements can also be taken in 60 seconds or less, which makes RMSDD quick and easy.

HOW CAN RMSDD BE USED TO CALCULATE HRV AND PLAN OPTIMAL ATHLETIC TRAINING?

The power of HRV as a training tool comes from establishing an RMSDD baseline. To establish a baseline, an athlete needs to wake up, strap on the eSense Pulse for a minute, and take a reading each day for one week. At the end of the week, if they average all of their RMSDD measurements, they will have a baseline RMSDD number.

In the future, if their RMSDD numbers fall below their baseline in the morning, they will know to ease off on training for optimal performance. If their RMSDD number goes above their baseline, they are more than recovered and can take on a challenging workout. In other words, higher RMSDD numbers correspond with more parasympathetic activity or a more recovered state.

RMSDD AND HRV LET YOU KNOW WHEN AND HOW TO TRAIN

In a perfect world, an athlete’s mind and body would be in total sync, and athletes would intuitively know how hard to push themselves. In reality, athletes may gradually stop making progress without knowing exactly why. They are either over or undertraining. They may attribute their fatigue to not working hard enough when, in fact, they are working too hard. HRV measurements like RMSDD give athletes an objective way to justify a rest day or, on the other end of the spectrum, prompt them to increase the intensity and volume of the training. Heart rate variability in athletes used to be available only to world-class athletes. However, with technologies like eSense Pulse, HRV analysis can be used by cyclists, runners, endurance athletes, and even gym enthusiasts.
