Impact of offshore sailing on HRV

By Tom Hayhoe I have been racing sailing dinghies, sportsboats and offshore yachts for over forty years, competing in world championships in several different classes. I still campaign a J105, and occasionally race a National Twelve and an SB20 sports boat, long after most of my contemporaries have had the sense to hang up their foul weather gear. I also run 10 to 20 miles a week just for fun and cycle around 80 miles a week because is the … Continue reading

Haute Route Alps

Observations from training & racing the Haute Route Alps

I just came back after completing the toughest challenge I have undertaken in years – the Haute Route Alps, which is a 7 day road biking stage race from Geneva to Nice with some of the best known Alpine climbs of the Tour de France. 20,000m of ascent over nearly 1000km of racing with 500 dedicated enthusiasts from around the World. Rather than tell the full story, I wanted to share a couple of interesting observations regarding my HR(V) during training … Continue reading

Using HRV to Manage Workplace Stress

Work and stress seem to go hand-in-hand, and more often in these days than ever before. While work isn’t all bad, the type of stress that we tend to feel at work isn’t exactly good for our health and overtime can wreak havoc on our mental and physical health, even leading to long-term health issues. Being aware of our stressors—which isn’t always as easy as you’d think—and learning to keep our stress levels in check at the workplace can improve … Continue reading

Heart rate variability, colds & acupuncture

By Mark Ballou I came down with my first real common cold this year, and in a while actually. Thought you might like to see how it reflected in my heart rate variability (HRV)… Onset of illness I came down with my first real common cold this year, and in a while actually. Thought you might like to see how it reflected in my HRV. My HRV baseline had been declining for some time which I had attributed to work … Continue reading

How accurate are consumer pulse sensors?

Not very – according to a review recently undertaken by CNET. Senior Editor Sharon Profis collaborated with Cardiologist Dr Jon Zaroff to compare some popular health tracker devices to medical ECG equipment at rest and during treadmill exercise at quite high heart rates. Dr Zaroff explains that whilst heart rate monitor chest strap devices are essentially a single lead ECG in a sweat proof packaging, and with very good accuracy, wrist worn optical pulse measurement sensors depend on patterns of light absorbed … Continue reading

John O’Regan’s weekly HRV Training Diary

Monday June 23rd.  HRV= 55 Green. Set the alarm for an early start and don’t know what I was thinking but I do remember switching it off and that ended my chance of an early recovery run to start the day.  Staying in bed might have been the right decision after checking my HRV as it was much lower than expected so I must be more tired than I realise.  Easy lunchtime run with emphasis on keeping my heart rate … Continue reading

John O’Regan’s weekly HRV Training Diary

Monday June 16th.  HRV= 63 Green. Woke early enough to chance a pre breakfast run and took the opportunity to experience early morning Venice.  Unsure of where I was going but I had a loose idea of a general direction that should get me a loop of 8-10K.  Started off running against the flow of rush hour which made the progress slow and then I started to enter a more industrialised part of the city and constantly made the effort … Continue reading

Energy Drinks and HRV RER chart

Energy drinks and HRV

Who, what & why As part of his PhD studies at the University of Minnesota, Kinesiology Department, Dr Mike T. Nelson looked at the impact of a particular energy drink (Monster) on heart rate, heart rate variability (HRV) and ride time to exhaustion in young recreationally active men & women. The team hypothesized that since most energy drinks contain carbohydrates and caffeine as their active ingredients that a 16 oz can of Monster would allow the subjects to ride for … Continue reading

John O’Regan’s weekly HRV Training Diary

Monday June 09th.  HRV= 65 Green. Woke without the alarm and made my way to the track after dropping my son to school.  Plan for today is 8*5K off 1K recovery similar to a recent session. Happy enough with the HRV as it’s just what I need for this type of session knowing that it can be quite intense / stressful.  Expecting to be alone today as the Track athletes are competing in the provincial championships and I know this … Continue reading

John O’Regan’s weekly HRV Training Diary

Monday June 02nd.  HRV= 54 Amber. Woke without the alarm to an expected result and the plan changes slightly but still want to make the most of the Bank Holiday Monday.  Decided to head for the Track again and tried not to think too much about what lay ahead as the Track is a very lonely place today with the surrounding amenities all closed. Was unsure about distance and just ran easy laps with a change of direction every 5K before … Continue reading
