An Interesting Conundrum

Tuesday, July 16, 2013

co•nun•drum
/kəˈnəndr<
1;m/
Noun
1. A confusing and difficult problem or question.
2. A question asked for amusement, typically one with a pun in its answer; a riddle

I’ll leave it to you to decide which meaning applies here!! emoticon

This morning I wore my new Polar HRM to Curves – and set it for a workout – It was also connected it up to the Curves system so that my heart rate was monitored by the system . The results were very interesting.
It actually stopped me after one of the machines – the Dip Shrug – as my heart rate had hit what it and Curves system considered dangerous – so I had to take a 3 sec break or long enough for my heart rate to drop back to a safe level!
Ok – so its looking after me – or maybe themselves – preventing over exertion. At the time it stopped me my heart rate monitor was reading 162 bpm – which is 105% of a resting heart rate of 65 bpm – which maybe just a tad high!!

I do have, and have always had a strong heart!! emoticon

But then when I got home and checked the results of my workout – I found I had been in the Fat Burning Zone for 2.35 min and in the Fitness Zone for 32.65 min.
According to the The Karvonen Heart Rate Formula my target heart rates during exercise should be
Target Heart Rate Results:
Your heart rate ranges (in beats per minute)
55%: 112 bpm 75%: 130 bpm
60%: 117 bpm 80%: 134 bpm
65%: 121 bpm 85%: 138 bpm
70%: 125 bpm


My average heart rate during my workout was 142 bpm and my max heart rate was 162 bpm. So I have to get substantial drop in my heart rate to get within the Fat Burning Zone of 121 bpm to 130 bpm. emoticon

And here lies the conundrum!!
I weigh 114kg (250lb) at present – so obviously I need to lose more – but I need to retain my fitness level too .
This means working at a considerably reduced level to drop my heart rate into the Fat Burning Zone for longer time during my workout. I suppose in one way its great to be told I am working too hard – ease up and slow down in a workout!! But if I do that I could lose fitness – which it is essential to keep at this level in order to stay on my feet – and despite what the books say – if I drop off for more than 2 days then I will lose fitness!! The joys of being old and mobility limited!! emoticon

This then raises the question – is there a “fat burning zone” at all?
Sparkpeople, and others do not agree that is the best zone to work in - see their article “Do lower-intensity "fat burning" workouts really burn more fat?”
www.sparkpeople.com/comm

q=60


However a lot of other renowned people do give credit to this theory – but really this is what it is – a theory.
One thing I do know is that over the last year or so I have certainly got stronger, fitter and gained more mobility and stamina – however I am not losing weight and my body fat percentage has stayed the same!! Another thought is that I have been working at this level for ages now – and I’m still going strong.!!

Well maybe not quite like this!!

Of course there are a number of reasons that I might not be losing weight – and all of them unconnected with the exercise – and there has to be a chance the HRM is wrong, set wrongly or faulty!! But its still an interesting question I feel.

What are your thoughts on this and what would you do in this position????

    The 'fat burning rate' is not important to me because yoou are not working as hard as you should.and could.

I use a combination of cardio and strength training. I use strength training to build muscles (they boost metabolism rate) and burn more energy. I use cardio to build aerobic capacity.

I wear a Fitbit for step accuracy and a Body Media Core armband to measure total calories burned. If I do it right, it works. I must log all my food accurately in order to get results!

As they say, you have to CHANGE your workouts frequently to keep it challenging. emoticon emoticon emoticon

    HMMM .... I THINK YOU GAVE THIS BLOG THE PERFECT NAME. YOU DO INDEED, HAVE A CONUNDRUM. BUT THEN I HAVE HAD 7 HEART ATTACKS AND THEY NEVER ALLOW ME TO GET MY HEART RATE THAT HIGH. MEDICATION STOPS IT FROM GETTING THAT HIGH SO I CAN STILL EXERCISE BUT THE RATE STAYS WHERE IT SHOULD BE. AND I DO BREAK A GOOD SWEAT.

    Interesting questions and problem. When I think about how much we both need to lose & how hard that we both exercise, I wonder if this can be correct. I personally feel better when I am working harder. I suppose I need to read the article in order to make a more intelligent decision on what to do. Thanks for sharing the journey with us. Love ya, emoticon

    I would tend to want to keep working at the level you are working out rather than backing off. But I guess you do need to shake things up in some way since you aren't losing weight.
