    Performance staff should be aware that HRV responses to concussion appear similar to trends associated with training fatigue. Communication with Sports Med staff is essential for interpreting in appropriate context. New case report.

    Another new study showing that pre-bed HRV is associated with sleep characteristics. Healthy adults (20-40 years old) who fell asleep faster and woke up less frequently through the night had higher HRV at bedtime.

    Focusing only on acute changes with HRV misses the bigger picture.

    Particulate matter, air fresheners, smoke, pollution, & other ‘volatile organic compounds’ all known to reduce HRV. Effects can go easily unnoticed because it’s harder to “feel” than physical or mental stress. Chronic exposure linked with greater long-term cardiovascular risk.

    Had a good reminder over the weekend that chemical stress impacts HRV. Spent a good part of Saturday breathing paint and cleaning product fumes. Hard to believe this is just ‘noise’ with recent stability in RHR and HRV.

    Lower vagal-related HRV during sleep is associated with greater future risk of having a cardiovascular event.

    More evidence that greater visit-to-visit systolic blood pressure variability is associated with future risk of cardiovascular disease.

    HRV at bedtime predicts subsequent sleep quality. Have a pre-bedtime routine that increases parasympathetic activity to improve sleep. 10 min of paced diaphragmatic breathing is an effective strategy.

    Associations between heart rate variability and other variables are likely recording position-dependent. This study found that post-waking HRV in the standing position was more strongly associated with self-reported stress symptoms than nocturnal HRV.

    Post-exercise fan cooling accelerates HR and HRV recovery In normotensive and hypertensive men. Restoring fluids and body temperature are two easy and effective ways to kick-start recovery.

    Seriously, we have an amazing IRB at GSU. Incredible turn-around time on protocols and very reasonable reviews.

    Same interval session yesterday, much better and more typical response today. Anxious to lift now but scared to find out how much strength I’ve lost. First week back after being sick is always the worst.

    I find HRV to be especially useful for guiding training after illness. Performed some light intervals yesterday for first time in a week since being sick. This normally increases my HRV but it crushed me today. Exaggerated internal response to light external load = back it off.
