Did I hear Heather say "when I was a modern pentathlete" at 5:30? That opens up a whole world of challenges. Would love to see a GTN v Modern Pentathlon video!!
Something not touched on is the perceived ambient temperature during the activity and its influence on HR. In my view swimming tends to be the coolest, followed by cycling which is cooler than running due to the higher speed. Consequently, my HR from lowest to highest is swim, bike, run. My perception of this may be biased however because I live in a hot climate.
Ran my 1st Olympic distance triathlon today..nothing ever goes according to plan and I got a flat on my back tire at mile 3 and just kept going final time 2.45 I watch these videos all the time love the channel
Swimming even lower I think because I’m basically crap at swimming and not physically strong enough in the specific swimming muscles/upper body to push myself to get HR up.
So it's that relative kind of load of the cardiac aspect compared to the muscle aspect and the muscle mass recruitment and how much your're recruiting of course in cycling it's much more of a it's so much more it's more of a local effect than it is in running.
Actually out guy did answer the questions, if you take the time to replay three or four times the knowledge is there, but the communication was... not superb?
@@mikewood9284 At one point Heather even describes the person that has been a triathlete all their life, and the answer is still extremely vague. As a scientist as he calls himself at the end of the video he needs to tells us helpful information rather than just 'everything depends'.
He did answer the questions, if you take the time to replay three or four times and scavenge it out, the knowledge is there, but the communication was... not marvelous?

Swimming has a hypoxic aspect so it’s making the heart work harder due to less oxygen. The HR zones should always be consistent as it’s just a metric used to gauge how hard your heart is working to pump oxygen to the working muscles. I’m a bit confused to what they’re both referring to here but I’m guessing they’re talking about their RPE relative to HR zones??? For example swimming is a harder or more technical discipline due to the potential risk of breathing in water or drowning making you increase your HR more than the other disciplines??? 🤷♂️ I need a beer 😂
There are some Garmin watches that can do it, also the polar Verity sensor, though you can't see it live if used only by itself, but paired with Form goggles you can see it live
Sorry,really love the GT Network, but this video was not it! Basically we got no real answer. It might have been more interesting to do a test with som GTN athletes. The professional just danced around the question without stating actual facts
Was trying to understand all this just today. Training to the MAF 180 theory atm and back to back 1hr sessions bike and run give such different results. Spend 1hr at 137bpm running burns 1/3 more calories than the bike, but an 1hr on the bike at 137 feels like so much more work. Wierd sciencey stuff.....
Using MAF 180 theory is about as pointless as 220-age for max heart rate. The trend line is correct but the tolerance on the data makes it unusable. Find your max HR with a test. Find your resting HR over a couple of weeks and then use HR reserve calculation. So much more accurate (within a few BPM of a lab based result typically).
Do you notice a difference in heart-rate between sports? Which sports are higher for you? Let us know in the comments 👇
Definitely when running!
I did not understand anything, nor I got any specific information, except that zones are different, but I already new this.
Did anyone get lost counting the number of times Jamie said the word modalities 🤔
He didn’t say much for how much he spoke

She won a silver medal in the Olympics in modern pentathlon.

It’s based on body position too. Lying down vs sitting down vs standing up
I always assumed that the diving reflex played a large role in having a lower heart rate while swimming
more when the water is quite cold, or when you really dive, but no big difference during warm water swimming
Love this, more science videos please! What's the latest with Fraser and the new presenter who hasn't yet appeared in a video?
awesome vid!

My max HR is higher running. Off road running it’s been up to 195 but on bike max is about 183.
Swimming even lower I think because I’m basically crap at swimming and not physically strong enough in the specific swimming muscles/upper body to push myself to get HR up.
Sorry, but I didn’t understand anything he was talking about. No practical use, I am afraid 😕

Definitely higher running compared to swimming, but I’ve done the latter for much longer.
Brilliant questions, totally useless woolly answers.

@@automotive474 Thanks a lot. I didn't fully understand until read this sentence repeatedly.

What are people's best solutions for measuring heart rate while swimming?

RPE is really useful for swimming.
OH1 Sensor with FORM goggles

I learnt absolutely NOTHING from this video!
Sometimes it's very hard for me understand British accent 😅😅
If that helps, you might want to try the "caption" feature of RUclips. Just my 2 cents;)
You can also slow the videos down.
You didn’t miss anything, just waffled on about nothing.

Today 1h cyclette at like 140/150 bpm 😂🥵
104 km cycling with average of 152bpm (a little over zone 2)
