    ADAM LOWE: Hi.I'm Adam.I'm a research specialist at Pennington Biomedical ResearchCenter, as well as a PhD student at Louisiana State Universityin Baton Rouge, Louisiana.At Pennington I work on exercise interventions,monitoring physiological data, as well asconducting performance testing for research trials.

  • 00:37

    ADAM LOWE [continued]: I also monitor physical activity to help determine eligibilityfor our research studies.The BioHarness is a chest worn devicethat monitors physiological data and transmits itto either a handheld device or a computer.The BioHarness measures data such as heart rate, breathingrate, core temperature, and body orientation.

  • 01:01

    ADAM LOWE [continued]: It can transmit that data in a live modeso that it can be monitored in the moment, as wellas storing raw data files that can be used for analysis later.[How can the BioHarness be used in research?]

  • 01:21

    ADAM LOWE [continued]: There are several types of clinical trialsthat could benefit from using the BioHarness.Exercise intervention studies, where participantsare coming into the same facilityand exercising several days a weekover a long period of time, certainlyfits into the scope of the BioHarness.Using BioHarness you're able to input participant

  • 01:43

    ADAM LOWE [continued]: data, resting heart rate, max heart rate, certain heart rateranges, as well as participant identifiersso that every time they come in, all that data is thereand they can be assigned the same BioHarness each time.And it makes analyzing the data and keepingthings organized much easier.

  • 02:05

    ADAM LOWE [continued]: During exercise performance studies,the BioHarness is very useful because of the live--the capability to monitor data livewhen participants are exercising submax or maximally.It's helpful to be able to verify heart rates arewithin safe ranges and have a constant physiological

  • 02:25

    ADAM LOWE [continued]: monitoring device.Studies involving athletic teams especially large teamscan benefit from using the BioHarness due to its abilityto monitor multiple subjects at once.A recent study that I worked on was observing American footballplayers.And we were able to see 20 of our participantsover multiple practice fields-- wewere able to see all of their physiological data

  • 02:47

    ADAM LOWE [continued]: on one device.Exercise intervention studies can certainlyuse the BioHarness effectively.The BioHarness software allows you to input participant datainto the software so that every time they come in,all the data is still there.And so that resting heart rates, max heart rate,or specific heart rate ranges that participants

  • 03:10

    ADAM LOWE [continued]: are supposed to be exercising at canbe saved within the software.Because of the live monitoring capability of the BioHarness,while participants are exercising,researchers can confirm that they're in appropriate heartrate ranges, as well as save breathingrate and core temperature.And adjustments can be made in the moment because

  • 03:32

    ADAM LOWE [continued]: of that live monitoring capability.The BioHarness, like I said, provideswith live and stored data files for researchers to use.The live files allow researchers to monitor data in the moment,while raw data files allow--are more oriented for statistical analysis

  • 03:55

    ADAM LOWE [continued]: after exercise, after the intervention is completed.The BioHarness is certainly one of the more expensivephysiological monitoring tools on the market.Devices such as the Polar might be less expensive.However, the quantity of data files that the BioHarnessprovides can certainly be beneficial to researchers who

  • 04:19

    ADAM LOWE [continued]: are looking at a little bit more in-depth analysison the back end.Here at Pennington, we used to use the Polar heart ratemonitors very frequently.However, more recently investigatorshave been requesting that we use the BioHarness becauseof the quantity of data that it provides,as well as its ability to track our intervals and a little bit

  • 04:41

    ADAM LOWE [continued]: more in-depth physiological analysis.A study that I'm currently working oninvolves asking participants to exerciseoutdoors for up to three hours.We have them put the BioHarness on beforehand,and when we return, we download all that raw data.And we can save it for analysis later.One component of the BioHarness software

  • 05:01

    ADAM LOWE [continued]: is called OmniSense Live, which provides the live datafrom the BioHarness.In this way, researchers can confirmthat the data is accurate because theycan see that the heart rates are within reasonable ranges,and all the physiological data makessense for what the participant is doing.And adjustments to the harness or swapping out straps

  • 05:26

    ADAM LOWE [continued]: can be made because they can confirm that the data isbeing provided accurately.The software also provides a heart rate confidencepercentage, so the researchers canconfirm that the device itself is providingaccurate data based on the feedback the device

  • 05:47

    ADAM LOWE [continued]: is receiving.Our exercise testing department uses that very frequentlyin order to confirm that the data that they collectedduring a performance test was accurate.So that when that data is provided to researchers,who might use it to prescribe percentages of max heart rates,they can confirm that data was accurate

  • 06:08

    ADAM LOWE [continued]: and that the software itself was receiving enough input in orderto make an accurate measurement.[What are some of the challenges of using a BioHarnessin research?]One of the most common challenges with the BioHarnessis its multiple components which can--

  • 06:30

    ADAM LOWE [continued]: which increases the risk for miscommunicationthroughout the system.The BioHarness modules themselveshave prongs that need to connect to the BioHarness straps,and the BioHarness strap relays via Bluetooththe physiological data to a receiver that'sconnected to a computer.

  • 06:52

    ADAM LOWE [continued]: And somewhere in that connection,a miscommunication can occur.As straps get older, as the modules themselves might getroughed up due to exercise, or if the receiver is notconnected to the computer properly, data isn't received.And so there's quite a bit of communication

  • 07:15

    ADAM LOWE [continued]: between those devices where an error or a drop in datacan occur.Because of the design of the raw data file storage,files can be overridden, and datacan be lost if it's not downloaded in a timely manner.The volume of data that can be stored on the BioHarnessmodules is substantial.

  • 07:37

    ADAM LOWE [continued]: However, because of that volume, sometimes data can be lost.And so it's very important to download the devicesfrequently and with care, naming them appropriately.One of the capabilities of the BioHarness softwareis to download nine different files from each exercise

  • 07:57

    ADAM LOWE [continued]: session.And so making sure you name all nine files the sameand that confirming that all nine of those filesare stored in the appropriate placeis very important, because it offers multiple opportunitiesfor data to be lost.I would advise researchers to confirmthat they would like the amount of data

  • 08:20

    ADAM LOWE [continued]: that the BioHarness provides.It's very important that the research staff is wellversed in using BioHarnesses.Because like I said earlier, there'squite a few places where miscommunication can occur,data can be dropped.And while they offer high quantity and quality of data,

  • 08:41

    ADAM LOWE [continued]: they are rather complicated to work through those issues.I would highly advise researchers to come upwith a well-thought-out naming convention in storagelocations for BioHarness data.Because of the volume of files that the BioHarness provides,it's very important that the data is organized and namedappropriately, and sorted so that when

  • 09:03

    ADAM LOWE [continued]: the data is being reviewed after the studyis over, that it's all there.And that researchers can be confidentthat they're looking at the appropriate participantfrom the appropriate session.On all of the studies here at Penningtonthat use the BioHarness, we have checklists and quality control

  • 09:26

    ADAM LOWE [continued]: trackers in order to make sure that all the data that weexpect to have is there and that it's all named appropriatelyso that we can feel confident when we providethe data to the investigators, that weare providing accurate data in allof the data that was collected.So in conclusion, the BioHarness provides both live monitoring,in a simple way, as well as a little bit more

  • 09:49

    ADAM LOWE [continued]: complicated raw data files for retrospective analysis.Because of the volume of data that the BioHarness provides,I think it's very important for researchersto be able to spend the time becomingfamiliar with the device itself as well as its softwareso that they can use it properly and collect the data that they

  • 10:10

    ADAM LOWE [continued]: would like to collect.My name is Adam.Thanks for watching.And I hope you found this video helpful.[MUSIC PLAYING]
