Chest Straps and Lactate Threshold Tests

Former Member
Former Member

I’ve got a FR255s.

Which heart rate straps work for the guided Lactate Threshold Test? Would the Garmin HRM Dual work for the test?  I can’t justify spending $180cad on the newest ones.

Any other brands that would work for the test?

  • I do however have an advice. I notice that your cadence is a bit low for your height. When jogging slowly, try to reduce your stride length instead of the cadence

    What cadence do you suggest I target roughly for my height ? I notice that yours was fairly stable at between 175 and 180 through your whole test.

    * edit: there is a "x2" next to your 30' Vigorous on your report. What does this mean ? (I can see a x2 in my report too)

    Hi dear JRKingOfBeer

    x2 means doubled active minutes that you get counted to your weekly score by doing your activity. 

    About LT test - may be it is too early to test your LT. You have to be able to run with constant pace and pulse for 10-20 minutes. For beginners it is difficult to impossible. I would suggest that you start slow with the steps here.
    By the way - you have good starting parameters. And your running track looks perfect!

    Thank you for that. I have now watched the video and suggestions would indeed be a good idea ! In fact, I think that's exactly what I need.

    Quick question: do you happen to know if the running activities MUST be done outdoor, as in with the GPS on ? Reason why I'm asking is because I'm living in Hong-Kong where a couple of weeks from now, it won't be possible to run outside anymore (too hot, too humid). Already now is really bordeline. This + the pollution. Could the running activities be done on the treadmill ? If you don't know no worries, I will give it a try and see what happens.

    Also, from the link you posted, am I to understand that only running and cycling activities will be suggested, not rowing activities ? I'm asking because I'm slightly more into rowing. But just asking.

  • Treadmill is OK as a warming up before/after other indoor activities, but you need min. 1 time weekly do it outdoors. IMHO, treadmills are like computer games vs. activities in the real world. It is better than nothing, but not enough to get all the metrics you need to get your performance index and setting up new exercises to make progress. 

  • Treadmill running is a great way to get in shape, but it is somewhat difficult for the watch to know how fast you are running, so the logs and suggestions car sometimes be misleading. The more you run outdoors with GPS, the better the watch gets at guessing your pace indoors. 

    People have however been doing treadmill running long before training watches and sensors were available. Remember that you can also control the running intensity based on how you feel. 

  • Regarding  cadence, it is common to aim for around 180 for dedicated runners, but there are big variation in preference. I would at least try to stay over 160. 

  • Thanks for the input guys, much appreciated. Very clear.
