URL: https://www.psypost.org/higher-aerobic-fitness-is-linked-to-lower-heart-rates-during-acute-stress/
A study in Austria examined whether aerobic capacity modulates psychophysiological responses to stress. The researchers found that people with higher aerobic capacity had lower heart rates during experimental stress conditions. The paper was published in Psychophysiology.
When a person faces a challenge, a demand, or perceives a threat, they experience stress. The body reacts with a stress response, a set of reactions that quickly increase alertness, heart rate, breathing, and the availability of energy. This response prepares the body for increased physical effort typically needed to fight a threat or flee from it.
The stress response is driven mainly by the sympathetic nervous system and a system involving the hypothalamus, pituitary, and adrenal glands. This system is called the hypothalamic–pituitary–adrenal (HPA) axis. The HPA axis releases the hormone cortisol, while the sympathetic nervous system stimulates the release of adrenaline. In the short term, this response can be useful because it prepares the body to confront danger or escape from it. Once the challenge has passed, the body returns to its normal state.
However, if the events that cause stress are intense, frequent, or never cease, so stress responses are initiated frequently or remain activated for too long, stress becomes chronic. Chronic stress can contribute to sleep difficulties, irritability, poor concentration, weakened immunity, cardiovascular problems, anxiety, depression, and various other health problems. People differ considerably in how strongly they react to the same event because stress depends partly on how a person perceives it and how able a person is to deal with the event. In some cases, a stressful day for one person can be a peaceful day for another.
Study author Peter Raidl and his colleagues hypothesized that physically fit individuals might be better able to cope with stress. More specifically, they hypothesized that physical fitness would be more relevant for coping with acute physical stressors than with psychosocial stressors. They conducted an experiment in which they tested whether physical fitness provides greater protection against stressors that include a physical component compared to stressors that are primarily social.
In this study, they operationalized physical fitness as aerobic fitness, assessed using a graded exercise test, and self-reported physical activity. Aerobic fitness is the ability of the heart, lungs, blood vessels, and muscles to supply and use oxygen efficiently during sustained physical activity. A graded exercise test is a treadmill or cycle test in which exercise intensity is gradually increased while heart rate, breathing, and sometimes oxygen consumption are measured.
Study participants were 59 healthy adults. Their average age was 27 years. Twenty-eight of them were women. They were required to maintain a regular sleep schedule for the time of the experiment, avoid traveling across multiple time zones in the weeks of testing, and refrain from intense exercise, supplement intake, or alcohol and other drugs for at least 24 hours before each experimental day. In addition, they were asked to abstain from caffeine and nicotine for 18 hours, and from eating, drinking caloric beverages, chewing gum, or brushing their teeth for 1 hour prior to testing.
Each participant took part in two experimental events on two different days at least a month apart. The experiments included completing a set of assessments at the start and then going through either the Trier Social Stress Test (TSST) or the Maastricht Acute Stress Test (MAST). The TSST consisted of a 5-minute mock job interview, followed by a 5-minute mental arithmetic task (a task where participants perform mathematical calculations in their heads) performed in front of a committee. The purpose of the committee was to induce social stress. The committee comprised one male and one female interviewer, both dressed formally and instructed to maintain neutral facial expressions and body language. Interviews were conducted by an opposite-sex interviewer (also to increase stress).
The MAST combined elements of the TSST with having the participant dip their dominant hand in ice water multiple times (as a physical stressor). The participants held their hand in the water for 60 to 90 seconds each time and alternated this with a mental arithmetic task. After completing these tasks, participants completed follow-up assessments of their stress response. Study participants wore a heart rate monitor during the procedures.
Participants gave saliva samples at the start of the experiment, while they were anticipating stressors, and after each stress test protocol. At the beginning of each experimental day, participants completed an assessment of depression, anxiety, and stress symptoms (DASS-21). They completed an assessment of anxiety before and after each stress test, and rated their stress level at each saliva sampling. Participants were initially given a 2-week physical activity diary, but due to low completion rates, the authors relied on a physical activity questionnaire (IPAQ) to assess their activity levels. On a separate occasion, they completed the graded exercise test, allowing study authors to assess their aerobic capacity.
Results showed that participants with better aerobic fitness (higher peak oxygen uptake) tended to have a lower heart rate during both stress-induction situations. This association did not differ between TSST and MAST stress-induction procedures. No other outcome was associated with aerobic fitness.
“Aerobic fitness was linked to lower heart rate during the experimental sessions, indicating a modest cardiovascular advantage under acute stress. Contrary to our hypothesis, this effect did not differ between the two stress paradigms, suggesting that the influence of fitness was not specific to the type of stressor. Aerobic capacity, therefore, seems to reduce cardiovascular load during stressful situations in a general manner,” study authors concluded.
The study contributes to the scientific understanding of the links between physical fitness and stress response. However, it should be noted that the study used acute, laboratory-based stressors. Studies looking into coping with severe or chronic real-world sources of stress might yield different results.
The paper, “Does Aerobic Capacity Protect Against Stress? Insights From Two Stress-Induction Paradigms,” was authored by Peter Raidl, Anja Vogl, Aljoscha Dreisörner, Barbara Wessner, Urs M. Nater, and Robert Csapo.

Whoever thinks this is broken, raise your hand!
Of course it breaks just when it has a completely new strap, and I ordered three spares just in case… This is so me.

My fitness tracker decided to toss in the towel during vacation so I had to get something new. As I had been enjoying the smartwatch functions I decided to upgrade to a proper watch.
As its main use is to track activities I wanted to check in on its heart rate tracking. Strapped on my chest strap (data collected through Strava) and hit a cardio class.
Long story short I have nothing to complain about. Looks really good.

"WiFi signals can measure heart rate—no wearables needed
Engineers prove their technique is effective even with the lowest-cost WiFi devices
Heart rate is one of the most basic and important indicators of health, providing a snapshot into a person’s physical activity, stress and anxiety, hydration level, and more.
Traditionally, measuring heart rate requires some sort of wearable device, whether that be a smart watch or hospital-grade machinery. But new research from engineers at the University of California, Santa Cruz, shows how the signal from a household WiFi device can be used for this crucial health monitoring with state-of-the-art accuracy—without the need for a wearable.
Their proof of concept work demonstrates that one day, anyone could take advantage of this non-intrusive WiFi-based health monitoring technology in their homes. The team proved their technique works with low-cost WiFi devices, demonstrating its usefulness for low resource settings.
A study demonstrating the technology, which the researchers have coined 'Pulse-Fi,' was published in the proceedings of the 2025 IEEE International Conference on Distributed Computing in Smart Systems and the Internet of Things (DCOSS-IoT).
A team of researchers at UC Santa Cruz’s Baskin School of Engineering that included Professor of Computer Science and Engineering Katia Obraczka, Ph.D. student Nayan Bhatia, and high school student and visiting researcher Pranay Kocheta designed a system for accurately measuring heart rate that combines low-cost WiFi devices with a machine learning algorithm.
WiFi devices push out radio frequency waves into physical space around them and toward a receiving device, typically a computer or phone. As the waves pass through objects in space, some of the wave is absorbed into those objects, causing mathematically detectable changes in the wave.
Pulse-Fi uses a WiFi transmitter and receiver, which runs Pulse-Fi’s signal processing and machine learning algorithm. They trained the algorithm to distinguish even the faintest variations in signal caused by a human heart beat by filtering out all other changes to the signal in the environment or caused by activity like movement.
'The signal is very sensitive to the environment, so we have to select the right filters to remove all the unnecessary noise,' Bhatia said.
The team ran experiments with 118 participants and found that after only five seconds of signal processing, they could measure heart rate with clinical-level accuracy. At five seconds of monitoring, they saw only half a beat-per-minute of error, with longer periods of monitoring time increasing the accuracy.
The team found that the Pulse-Fi system worked regardless of the position of the equipment in the room or the person whose heart rate was being measured—no matter if they were sitting, standing, lying down, or walking, the system still performed. For each of the 118 participants, they tested 17 different body positions with accurate results.
These results were found using ultra-low-cost ESP32 chips, which retail between $5 and $10 and Raspberry Pi chips, which cost closer to $30. Results from the Raspberry Pi experiments show even better performance. More expensive WiFi devices like those found in commercial routers would likely further improve the accuracy of their system.
They also found that their system had accurate performance with a person three meters, or nearly 10 feet, away from the hardware. Further testing beyond what is published in the current study shows promising results for longer distances.
