Swimming Data - Apple Watch 2 v Fitbit 2

[mbeaumont]

Hi all,

I am trying to loose weight and have taken up swimming.

I've had an apple watch 2 since its release and been swimming since last November. So far I have only lost 2kg and wanted to check the Swimming Data (Calories)

So, here are my stats

I am 48, and my weight is
92kg - 203 lbs
My pool is 25 meters
I generally swim breaststroke at 5'17 per 100m on average.

Today I went to the pool with my Apple Watch 2 and the results were :-

Active Calories = 665 Cal
Total Calories = 717 Cal
Distance = 1,020m
Total Time = 0:54:03
Avg Heart = 104 BPM

I also had a Fitbit 2 on my other wrists

The data from that is showing

Total Time = 0:43:31
Total Calories = 330 Cal
Distance = 1,250m

I was shocked to see the hue difference in calorie burn, so I went to some swimming calculator websites to check the approximate results

Putting in to the website the Apple Watch Distances etc here were the results

www.swimmingcalculator.com
Suggested that 367 Calories had been burnt, learning towards Fitbit

http://caloriesburnedhq.com/calories-burned-swimming/
Suggested that 461 Calories has been burnt, again significantly lower than apples reading

http://www.flaswim.com/calories-burned-swimming-calculator/
Suggest that 580 Calories has been burnt

It is clear that something is amis here, and may explain why I am am not loosing weight if those numbers from apple are used as part of my daily calorie exercise total.

Am pretty confused here, not sure which reading to take, apple or fitbit.

Anyone else experienced this or maybe my watch is faulty?

The numbers are all over the place no matter what you use. About the best you can do is use it as a guide and not depend on accuracy.

That's the biggest danger with fitness trackers and why studies often show that people gain weight with them. They're very helpful as a general gauge, but you can't do a one to one calorie count with them.

I've found swimming with my Apple watch to be extremely accurate as long as all I'm doing is a basic swim (not just kicking or a swim drill). I swam 10,300 yards and my watch counted it as 10,325 yards.

Apple Watch takes into account your heart rate into their calorie measurements i think. Fitbit 2 may not be able to read the HR while in water. Your swim calculators the same...no HR data to input.
