GPS is required to complete the test. Next, hold MENU. Then select Training > Lactate Threshold Guided Test or Training > Lactate Threshold > Do Guided Test (remember you need a heart rate monitoring strap for this to work) Start the timer, and follow the on-screen instructions like to warm up for 5-10 mins.
Zone 4 is our Threshold Zone, often 95%-105% of your threshold heart rate. This is where training intervals can get hard. You do long enough intervals just below your threshold to really get your body used to working hard. Remember, lactate threshold is the pace we can maintain for about an hour (depending on fitness level).
Your lactate threshold is the level at which the intensity of exercise causes lactate to accumulate in the blood at a faster rate than it can be removed, making it the border between low-
Lactate threshold training involves increasing your exercise intensity until you train at or slightly above your LT heart rate. This training can include interval training or steady-state training. Interval LT Training Example: Perform three to five 10-minute high-effort intervals at 95-105% of your LT heart rate twice a week with 180 seconds
At beginning of a threshold run (after the warmup), I haven't accumulated any metabolic byproducts yet, so my pace/heart rate aren't quite matched yet. I gradually easy into what I believe will be my tempo pace. Once the pace and heart rate are correlated, I keep a constant heart rate. If my pace slows down over 3-4 km, I am above lactate Heart Rate Training Zones Calculator. Zone 4 @Z4, LACTATE THRESHOLD. Intensity: 89-94% of your max HR. Also known as the anaerobic threshold, this type of training increases maximum performance capacity enhances lung capacity, and improves high-speed endurance. That said, this type of training is very challenging - it's not an effortI've recently done a couple of lactate threshold tests using a chest strap heart rate monitor and got a score of 163 bpm (with my VO2 max being 50). When I use the lactate threshold score as the basis of my zones, the watch recalibrates them and renames zone 2 from 'easy' to 'low aerobic'. With the top of the 'low aerobic' zone being 145 bpm..
