Es un indicador de la "forma", o dicho de otro modo, la "frescura". (1990) emphasized in discussing the parameters of the criterion performance tests used to establish the time constants and gain factors of the impulse response model: “They must represent best-effort performances on a standard test that is appropriate in length and intensity of effort to the competition event being prepared for.” (emphasis added) In other words, the specificity principle always applies, and this fact should not be overlooked when using (or evaluating) the Performance Manager. While some information about how to best use this analytical tool is included, readers should also see this article by Hunter Allen for more information on this aspect of the topic. Knowledge of the relationship between the volume and intensity of training on the one hand and the resulting improvements in performance on the other is obviously critical when attempting to design the optimal training program, i.e., one that maximizes an individual’s performance ability at the time of key events while also avoiding illness, injury, or overtraining. While zero indicates the athlete has reached a training equilibrium, complete recovery is often needed for peak performance, especially for long-distance racing. Training Stress Score (TSS) is a formula developed by Andrew Coggan from TrainingPeaks describing the workload of a training base on your FTP and intensity factor (IF). Since each individual is different and since the answer to this question may depend in part of the particular aspect of performance that one is attempting to maximize, previous experience is often the best guide here. In practice, this entails deciding how much ATL, and hence CTL, should be reduced so as to result in an increase in TSB. On the other hand, the calculations in the Performance Manager are sensitive to the time constant used to calculate ATL, and hence TSB (since TSB = CTL – ATL). Intensity factor is a simple calculation comparing normalized power to Functional Threshold Power (FTP). Again, experience indicates that younger individuals, those with a relatively low training load, and/or those preparing for events that place a greater premium on sustained power output (e.g., longer time trials, 24 MTB races, long distance triathlons) may obtain better results using a somewhat shorter time constant than the default value, e.g., 4-5 d instead of 7 d. Conversely, masters-aged athletes, those with a relatively high training load, and/or those preparing for events that place a greater premium on non-sustainable power output (e.g., shorter time trials, criteriums) may obtain better results using a somewhat longer time constant than the default value, e.g., 10-12 d instead of 7 d. (Of course, since athletes preparing for longer events often – but not always – “carry” higher overall training loads, this tends to constrain the optimal time constant more than would otherwise be the case.). Keymaster. 0. This is especially true of CTL, and hence also of TSB, due to the long time constant used in its calculation. These individuals used the Performance Manager during the 2005 and 2006 racing seasons, and in doing so provided valuable feedback about how to best apply the approach. Same for Ramp Rate. 1-hour workout in endurance zone would be around 60 TSS. Default values of 42 days for CTL and 3-10 days for ATL ATL is same formula as CTL, simply use ATL instead and the relevant TC. Las líneas irregulares son CTL (azul), ATL (fucsia) y TSB (amarillo). 6) In addition to the absolute magnitude of CTL, considerable insight into an individual’s training (and/or mistakes in training) can often be obtained by examining the pattern of change in CTL over time. Thus, to obtain good results using the Performance Manager approach, it is important that these TSS values be based upon valid, up-to-date estimates of an athlete’s functional threshold power. The time course of changes in performance in response to repeated bouts of training is therefore described by equation 1 below: Equation 1. Is this CTL formula equivalent and what makes it hold? With this perspective in mind, it was recognized that eliminating the gain factors ka and kf (or k1 and k2) from the impulse-response model would solve two problems simultaneously: 1) it would remove any uncertainty regarding the precise values to use (with the price being that interpreting the results of the calculations becomes as much a matter of art as it is of science – see more below), and 2) it would allow substitution of simpler exponentially-weighted moving averages for the more complex integral terms in the original equation (because at least qualitatively they behave the same way). Indeed, as Morton et al. The ideal training zone for TSB falls between -10 and -30. Those who train more, mostly or entirely outdoors, and/or in a less structured fashion would likely fall towards the lower end of this range, whereas those who train less, frequently indoors, and/or in a more structured fashion would tend to fall towards the upper end of this range. In the impulse-response approach, the quantitative relationship between training and performance is modeled as a transfer function, the input to which is the daily “dose” of training (i.e., combination of volume and intensity) and the output of which is the individual’s actual performance. Con este valor lo que se analiza es la carga de entrenamiento que tienes desde los últimos 42 días teniendo en cuenta el TSS. have proposed a modification to the original model that explicitly recognizes this fact and which results in a slightly improved fit to actual data, this modification further increases the mathematical complexity and requires an even larger amount of data be available to solve the model (see below). 5) Although most attention is likely to be focused on application of the Performance Manager to managing the peaking process, other benefits to this approach clearly exist and should not be overlooked. Changes in fitness, fatigue, and performance as predicted using the impulse-response model. The TSB I can manage week or 2 before, to get it slightly positive, and accept the CTL drop. ATL is generally a marker for short term input, generally the past 7 days, where CTL is a longer term marker, up to 6 weeks. Make sure you’ve had a chance to review all past data and ensure that the PMC is an accurate reflection of the athlete’s recent training. The training load that encompasses a longer time period, most likely 21-42 days. TrainerRoad uses a simplified equivalent calculation, displaying your rolling average TSS from the last 6 weeks with no exponential weighting applied. Alternatively and/or in addition, the following approximate guidelines may prove useful when analyzing prior data: a TSB of less than ‑10 would usually not be accompanied by the feeling of very “fresh” legs, while a TSB of greater than +10 usually would be. Moreover, the model has also been shown to accurately predict changes in performance-related parameters considered indicative of training (over)load and/or adaptation, such as serum hormone (e.g., testosterone) or enzyme (e.g., creatine kinase) levels, or psychological measures of anxiety or perceived fatigue. The training load that encompasses the most recent training load, most likely the last 3-14 days. The obvious caveat here is that it's all just modeling. The following hints, tips, caveats, and limitations are offered in hopes of speeding up this process. As can be seen in this figure, performance (i.e., the difference between the two terms of the equation above) is initially predicted to be diminished or degraded, due to the acute, negative influence of training. Checking Model relationships in CakePHP. Training Stress Balance is the “ready to race” metric where the more negative the number, the deeper in “the hole” an athlete is and the more positive the number the more recovered and ready perform the athlete is. Of course, since changes in CTL are “driven” by changes in ATL, this means that any sudden increase in the training load (e.g., training camp, stage race) must be followed by an appropriate period of reduced training/recovery, so as to avoid too great of an overload. Given the rather robust behavior described above, the impulse-response model would appear to be a highly useful tool for coaches and athletes wishing to maximize their probability of success in competition, and some prominent national team programs in cycling have attempted to exploit this approach. TrainingPeaks uses 42 days, if I recall. The impulse-response model of Banister et al. Failure to apply this information when planning and evaluating training programs, tapering schemes, etc., means failure to take maximum advantage of available knowledge. The impulse-response model has therefore been used to optimize training/tapering regimens, evaluate the impact of training in one sport (e.g., running) on performance in another (e.g., cycling), etc. Doing anything more than 300 TSS would have resulted in a positive ramp, as 300 TSS/week is a CTL of 43. your TSS score is trending up — that’s explained next) your fitness is going to go up.Vice versa if you’re posting less frequent training sessions or not training as hard, the CTL trend will go downwards. Acute Training Load looks at how your most recent training impacts your body. At the present time, however, WKO+ only allows use of TSS as the “input function”. There is a correlation between fatigue and fitness scores—when your fatigue score is less than your current fitness score, you will normally see a positive TSB value. So, negative TSB implies that your long-term CTL is increasing. Understanding the performance management chart in Training Peaks: ATL, CTL and TSB explained. The root of all data in TrainingPeaks comes down to duration and intensity which produce a Training Stress Score. So doing 1,273 TSS will always ramp it by an insane amount, even if you had a CTL of 100. The concept of … 1. CTL* is a superset of computational tree logic (CTL) and linear temporal logic (LTL). However, we also want to make sure that we understand the near term and long-term impacts of their training. ATL is subject to the same issues as CTL and should be treated in a similar way although ATL and CTL are read as acute versus chronic (hence the acronym). That is, the “composition” of training is just as important as the overall “dose”, and the usefulness and predictive ability of the Performance Manager obviously depends on the individual workouts being appropriately chosen and executed in light of the individual’s competition goals. The exact number depends in part on the particular situation in question, but from a purely statistical perspective somewhere between 5 and 50 measurementsÂ, Even when an adequate number of performance measurements are available, the fit of the model to the data is not always accurate enough for the results to be helpful in projectingÂ, As illustrated by the data shown in Table 1, the values reported in the literature forÂ, Chronic training load, or CTL, provides a measure of how much an athlete has been training (taking into consideration both volumeÂ, Acute training load, or ATL, provides a measure of how much an athlete has been training (again, taking into consideration both volumeÂ, Training stress balance, or TSB, is, as the name suggests, the difference between CTL and ATL, i.e., TSB = CTL – ATL. ), Easy Workout – An easy workout will result in a TSS score that is 10-25% below your current CTL (TSS for an easy workout would be 35-40 TSS). In both cases, however, CTL, ATL, and TSB would still be good indicators training load and adaptation. 1. As coaches, we want to ensure that … ATL: Acute training load. You can bring down high ATL scores by doing recovery (low TSS) workouts in addition to rest days. Think of Chronic Training Load as a measure of your true fitness. Or, to put it another way: if, as Dave Harris has put it, the body responds to training “like a Swiss watch”, then logically this information could, and should, be put to use by coaches and athletes wishing to maximize performance. The decision was therefore made to incorporate the idea into version 2.1 of the program WKO+ as a new chart. Your example is not equivalence assume a transition system by two state which all of them are initial, and there is a loop in state which satisfy \phi. TSB is not as a predictor of performance but as a measure of how adapted an athlete is to their training load. It’s imperative to set the athlete’s zones correctly before you can have any confidence in the information being produced. Similarly, a long-time powermeter user who hasn’t paid sufficient attention to tracking changes in their functional threshold power may not wish to rely on their previous data, or they may be without their powermeter for a lengthy period of time (e.g., while it is being repaired). TSB is the difference between the two, basically showing you how "fresh" you are, if you're over or under training, etc. 1-hour workout at our FTP level would be exactly 100 TSS. CTL: Chronic training load. where pt is the performance at any time t, p0 is the initial performance, ka and kf (or k1 and k2) are gain terms relating the magnitudes of the positive adaptive and negative fatigue effects (and also serving to convert the units used to quantify training to the units used to quantify performance), τa and τf (or τ1 and τ2) are time constants describing the rate of decay of the positive adaptive and negative fatigue effects, and ws is the daily dose of training.
