Thus, if there was enough break to get a burrito you should restart the TSS computation. The term “burrito break” was coined in this context. Even Coggan, Friel, Liversedge (GoldenCheetah), … can’t agree on a particular number. So, how much of a break to include in the calculation is an ongoing discussion. Although you expended the same Joule overall in both rides. There is a builtin metric (Efficiency Factor) which relates Normalized Power to Average HR and 1-5-10-20-30-60 min Peak Power HR metrics which compute the average HR for the corresponding Peak Power duration which could be used to track the evolution of your Power/HR relationship in Metrics Trends charts. However, then a continuous base ride of 3 hours would result in a lower TSS than the same base ride with a 1-hour coffee break in between. This would also be problematic with the way NP and thus IF is computed since it needs a rolling average window of 30 seconds.įor the other extreme you would include all zeros. But as we all know your body is still working after you stopped pedaling. One extreme would be to not count zeros at all. The question is: how many consequential zeros (W) should you count towards the TSS? In certain apps, like GoldenCheetah, you’ll get a different TSS value depending on if you use Garmins auto-pause feature or not. The first release of the Golden Cheetah GUI. BMC (Time Machine) Official BMC Time Machine Owners Thread New BMC Tri/TT bike photo Canyon Speedmax. Adds the Critical Power Plot, which shows the highest average power youve achieved for every interval length over all your rides and the selected ride. Which is, broadly speaking, a result of time having a bigger impact on the TSS calculation than the lowered IF. Charts: Added Performance Manager (Eric Murray). Every time you stop or coast your TSS will still rise. These results probably explain why b3 is a power which can be maintained for a long time but not beyond about l h in an average subject.This is a very interesting discussion because it also concerns how TSS is computed. Nevertheless, slope b3 represents a workload corresponding to a slight but significant drift of heart rate or oxygen uptake. The workload that corresponded to a lactate steady state was not significantly different from b3 (68.8 +/- 6.0 vs 68.7 +/- 6.3% MAP). The second objective was to study the physiological significance of the critical power (slope b3) of whole-body work (cycling). Consequently, slope b3 should be considered as the critical power instead of slope b1 as in some studies in the literature (Moritani et al, 1981). Moreover, the exhaustion times at 60 and 73%,MAP were significantly correlated with slope b3 (expressed in %MAP) but not with slope b1. Each metric is displayed in a different color on the graph. Then, from it and your FTP, it can deduce a relative intensity or intensity factor. It will first calculate a normalized pace or power for your activity. Realtime A Realtime chart displays a graph over time of the selected metrics, as you ride through your current training session. From this FTP and your actual output level during the activity, 3record can calculate the metrics below introduced by Coggan in 4, Allen & Coggan. Exhaustion times corresponding to power outputs equivalent to b1 and b3 were equal to 29.0 +/- 19.1 min and 48.6 +/- 9.8 min respectively. Once the workout is started additional curves are displayed showing Power, Wbal, Cadence, Heart Rate and Speed smoothed using a 5 seconds moving average window. Slope b1 was significantly higher than slope b3 in 10 subjects who performed 5 cycling exhausting exercises (60, 73, 86, 100 and 120% of maximal aerobic power (MAP) in watts). Body Weight in Pounds: Interval 1 Average Watts: Interval 1. What is Critical Power (CP) CP is the power you should be able to sustain over an all out 60 min effort. The first objective of the present study was to compare the values of slopes b calculated from whole-body work of short duration, ie maximal and supra-maximal cycling exercises (slope b1), with the values calculated from the same work, the durations of which were between 3.5 and 35 min (slope b3), as in the protocols used by Scherrer and Monod (1960) for body-part work. There is a builtin metric (Efficiency Factor) which relates Normalized Power to Average HR and 1-5-10-20-30-60 min Peak Power HR. Field Testing to Determine your Bike Training Zones using a Power Meter. The slope b in the equation is termed the critical power and has been proposed as an index of the capacity to perform work over a long period of time. The relationship between exhaustion time (t(lim)) and the work performed at the end of constant-power exercises can be described by a linear relationship (Wlim = a + b t(lim)) for work involving the whole body (eg cycling) or part of the body (eg knee extensions).
