Summary

What is already known about this subject

• Acute exercise may lead to subsequent energy expenditure compensation.
• Intensive exercise may favor a higher compensation than low or moderate exercises.

What this study adds

• This post-exercise compensation might occur only in overweight/obese youth and not in lean.
• This work used objective measures of energy expenditure compare to previous work.

Background

Physical activity is mainly used in weight control strategies to favour energy expenditure. Some evidence suggests that exercise might not have the expected impact on energy balance, and may actually cause a decrease in the subsequent physical activity energy expenditure.

Objective

To question the impact of an acute exercise session of varying intensities on daily energy expenditure in lean and obese adolescents.

Methods

Data from three separate studies conducted in lean and obese 12–15 years old adolescents (study 1: 12 obese; study 2: 10 obese and nine lean; study 3: 15 obese) have been used. Daily energy expenditure (DEE) was assessed in studies 1 and 2 during an exercise condition with an exercise bout at 70%VO₂max (EX) and a rest day (REST) (using Actiheart and Armbands, respectively). In study 3, DEE was assessed in calorimetric chambers during (i) a high intensity exercise condition (HIE – 75%VO_2max) and (ji) a condition with a low intensity exercise (LIE – 40%VO₂max) and (iii) a rest condition (REST).

Results

Morning energy expenditure was significantly higher during the exercise conditions whatever the intensity compared with rest. Afternoon energy expenditure was significantly lower following HIE compared to the rest condition in studies 2 and 3. Afternoon energy expenditure was not significantly different between LIE and REST in study 2. Total DEE was not significantly different between conditions in the three studies.

Conclusion

Obese adolescents seem to show a compensatory response to an acute session of HIE (>70%VO₂max) by decreasing their following physical activity energy expenditure. Although HIE favours body composition, physical fitness and metabolic profile improvements, this induced compensatory energy expenditure response has to be considered to optimize its effect on weight loss.

BodyMedia on TV again: The Living Room Ch10, Friday, 15th March at 8.30pm

Okay,  I guess you’ve heard it before but I do have to let you know of the significant happenings, and yes, the Armband is going on commercial TV again.  This time with Channel 10 on The Living Room.

They used  it to showcase a volunteer’s poor energy balance and low physical activity after the birth of her first baby. The data was reviewed by experts so there will be some really interesting commentary here.  Perhaps the most surprising thing is that it all seems to have been caused by lack of sleep from the baby waking up – data curtsey of the Armband.

As you would expect from the Armband and commercial TV it all has a happy ending.

This is a great illustration of how the Consumer Version of the BodyMedia Technology can be used to get people back on track with a combination of key relevant information, education and motivation.

That time again : Friday, 15th March at 8.30pm – Ch10

Best regards to all

Making Couples Happy and SenseWear – A SHOW NOT TO MISS

The BodyMedia Armband is on TV Again!!!  This will make the sixth time it has featured in the last two years but it has been used many more times than that.

Enough with the Armband promo… This show is simply the best television you will watch this year. It’s a follow-on from the “Making Australia Happy” show that they did over a year ago and this one has really knocked the ball out of the park.  It’s not just applicable to marriages but to all or our relationships… and our general happiness. In many ways it’s a real eye opener.

Put the date in your calendar for the next 3 weeks and keep the date. If you missed last week’s episode it’ll be available for a while on-line at http://www.abc.net.au/iview/#/series/12212  but I believe it expires in 10 days!

And it’s not just me saying so:

*** 8 out of 10   SHOW OF THE WEEK *** Sun Herald

BEST ON THE BOX – …”many couples could learn a lot from this intriguing doco”  the Sunday Telegraph

Or you can go to their website and take the test to check out your individual happiness or couples happiness…and please email this on to all your friends.

Who wouldn’t want to spread some happiness?

Sleep estimation using BodyMedias SenseWear™ armband in patients with obstructive sleep apnea Sharif MM, BaHammam AS – Ann Thorac Med

“No significant difference in OSA patients between BSA and PSG with regard to TST, total wake time, and sleep efficiency.”

This paper really validates the use of SenseWear for sleep assessments.  No other strap on device is capable of this kind of accuracy without EEG and EMG.

The results show that BodyMedia is by far the most accurate overall and for longer periods of time.  There are other monitors that make very good assessments of specific activities.  For instance it isn’t hard to find an algorithm that is reasonably accurate for activities such as walking and running using just accelerometers. What this study proves is that SenseWear (and BodyMedia FIT) is accurate across the board of all kinds of activities and with very little bias at the end of the day (literally).

This is a fantastic endorsement of the BodyMedia system which makes use of multiple sensors (not just one) to provide additional differentiation for the activities thereby providing a better overall result. It also rates as the most user friendly – maybe because it’s really easy to determine when the subject took it off… but there are many other factors that contribute to this.

Please have a think about who you know that doesn’t use the SenseWear system, who could benefit from it in their research or clinical practice, and consider forwarding this link.
