To improve our endurance, we want to be more efficient at an aerobic intensity. To improve our speed, we want to have a higher anaerobic capacity. Besides doing "field testing" like the Swim CSS, Bike FTP and Run TT, one scientific way to test is how well the body processes muscle lactate. If you've ever done a Lactate Threshold Test (LTT), here's how the test administrator interprets the lactate measurement to determine your training zones. The LTT is performed by starting the athlete a warmup at a very easy intensity. We'll use the run discipline for this example. The athlete will walk on a treadmill for 10 minutes before starting the test and once the test starts, the intensity is increased every 2 minutes. At the beginning of the 10 minutes, the test administrator takes 4 metrics - pace, rate of perceived exertion (RPE), heart rate (HR) and lactate millimoles per liter of blood with a blood sample and lab kit. The lactate compared to the pace is the primary metric and the HR and RPE are secondary but useful to confirm and interpret the data. The administrator takes those same 4 metrics at the end of the 10 minutes and every 2 minutes there after. Every 2 minutes the treadmill pace is increased by 30 seconds of pace (11:00, 10:30, 10:00, 9:30 and so on). There are two key inflection points the test administrator is looking for. When the intensity is increased and the lactate level remains the same as the previous level means that the subject athlete is predominantly aerobic (zones 1-2). When the lactate level increases and levels out after each increase the athlete is in between aerobic and anaerobic (zone 3). When the lactate level continues to rise without an increase to intensity, the athlete is above lactate threshold (zone 4-5). Our News is sponsored by Buddy Insurance.

New Garmin Varia RCT715 tail light has a camera to record your crashes The Varia's high-definition camera will record everything behind you and its radar will alert you to approaching vehicles. Garmin has released the Varia RCT715, a new version of its tail light that features a high-definition camera to record any incidents out on the road. The Varia RCT715 features the same radar technology as its predecessors. When paired with a Garmin bike computer or smartwatch, the Varia will alert users to vehicles approaching from behind up to 140m away. Garmin says the device can be paired with selected cycling apps such as Ride with GPS. This will enable users to overlay maps with the radar notifications. Garmin claims the Varia RCT715's tail light can be seen up to one mile away in daylight. The camera records continuously and will save footage if an incident is detected. Garmin says the Varia's camera will "capture sharp, clear footage" at up 1080 pixels and 30 frames per second. The camera will record constantly when the Varia is in use. If an incident is detected, via Garmin's Incident Detection feature, the camera will automatically save footage from before, during and after the event. According to Dan Bartel, Garmin's vice president of global consumer sales, this is to provide users with evidence of an incident "should they ever need it". However, the camera also provides more recreational functions, in line with how you might use a GoPro. Via the Garmin Varia app, users can access the video footage, transfer files and customise the camera's settings, to do things such as overlay data, including speed and location. Garmin says the use of the camera will be prohibited or regulated in some jurisdictions, adding that it is the responsibility of the user to know and comply with applicable laws and rights to privacy. While Garmin has added a camera to the Varia, it has retained the radar and tail light functionality of the device. Like the previous Garmin Varia RTL515, the radar on the new version will still detect and alert users to vehicles approaching from behind to the same distance of 140m. Similarly, the tail light on the new version is said to be visible up to one mile away in daylight, which is the same as the Varia RTL515. But while the RTL515 has a claimed battery life of up to 16 hours, the RCT715 has a shorter claimed battery life. The Varia RCT715's batt
