A very good pro can do around 5.85 watts per KG for 60 minutes(425 watts on 160# rider), but the kicker is, they can do a bit less, repeatedly throughout the Tour. The same is true of cyclists who lose weight but suffer a drop-off in maximum power — something we’ll return to. Let’s put this math to work in an example. By creating a goal and implementing sensible and healthy lifestyle changes, we can create healthy body composition improvements, usually by decreasing our percent body fat. On an undulating road, however, power-to-weight begins to matter more. I did a set of 20 last night on an overpass. You've dropped from the magic 4.00 w/kg to 3.78. The rule relates to how many Watts (W) of power are needed per pound (lb) of airplane, and the approximate values range from 50W to 200+W. At your weight and speed, given the grade, your output probably averaged about 240 watts, which is 2.42 watts/kg, which places you in the untrained category on the Cycling Peaks WKO scale. Because these sessions are quite demanding, make sure you build in sufficient recovery time into your weekly schedule — it’s during recovery that your muscles adapt and become more powerful. your bodyweight — is vitally important too. At 90 kg, that’s 270 watts – which means 270 J (of energy) per second. Generally, untrained riders have an FTP below 2.0 w/kg for men and 1.5 w/kg for women, while professional racers may be capable of sustaining more than 6.0 w/kg for men and 5.5 for women. You’ll first want to add your weight, and then you can click on the W/kg button at the top right of the graph and the values are shown as watts per a kilogram. Moreover, an attempt to reduce weight when your body-fat levels are already quite low can lead to muscle mass loss as well as fat loss. power in watts ____ W… Notably, the median (50th percentile) twenty minute effort in watts per kilogram for males and females is exactly the same at 3.80W/kg, which means the average male and female Cycling Analytics user should be able to ride up a mountain at about the same speed. Studies have shown that performing heavy resistance training for the key cycling muscles (quadriceps, hamstrings, buttocks and calves) not only boosts muscle efficiency, it can help prevent the loss of muscle power during periods of high-volume training, or during periods of weight loss. You get above 3.75-4.25 and those are local elite racers. Power-to-weight ratio (or specific power or power-to-mass ratio) is a calculation commonly applied to engines and mobile power sources to enable the comparison of one unit or design to another. Unlike muscle tissue, excess body fat blunts power-to-weight ratio and contributes nothing to power output. your sustainable power output); you’ll almost certainly lose a bit of excess body fat in the process. What matters in cycling is the number of watts per kilogram, which takes into account a rider’s weight and size. Elevation definitely plays a key role. Power is measured in watts per channel, and the decision about how much power you'll need should be based on criteria including: Whether a trip to the mountains or just your local hills, power-to-weight is important. Let your body clock decide. We'll get to this a little bit later in the discussion. Good point, as long as the impedance of the KG 5.5 doesn't dip too low for the amplifier, the 35 watts should allow him to experience the feeling of 109 dB peaks of a grand piano crescendo. There's no point in weighing 75 kilos and knocking out 300 watts at threshold if you drop to 70 kilos and can only produce 265 watts. Of course, it’s worth bearing in mind that, in a real-life scenario, the heavier rider is likely to be physically larger and have greater frontal surface area, increasing their aerodynamic resistance further (a discussion to be explored another time). >>> Cycling training plans: get fitter, ride faster and go further. Yes, more miles might result in reduced bodyweight, but add too much extra volume and you run the risk of fatigue and burnout. People who race regularly may be 3.0-3.75. As to your testing: a VO2max of 62.6ml/kg/min at 69.4kg (4.34l/min). A 90-kilogram (200-pound) rider will generate roughly twice the power of a 45-kilogram (100-pound) rider to ascend at the same speed. Using data on rolling and aerodynamic resistance, we can calculate that an 80kg rider would have to maintain an average power output or around 298W, requiring a power-to-weight ratio of 3.73W/kg. Of course Nibali had the assistance of his team and other riders around him (al… Example: Cyclist A weighs 167 pounds or 76 kg and his 20-minute TT power is 275 watts. A rider who averages 6.8 … takes years and years of dedicated practice, and of course good genetics doesn’t hurt. In simpler terms, watts measure how hard you work. You need to be a bit more focused than simply adding more miles. 2. Let’s say your goal is to get your functional threshold power (FTP) from 3.0 to 3.5 watts per kilogram, a competitive amateur goal. what should be my average watts basing on my stats. Photo: Andy Jones. More of a 'rule of thumb' than a hard and fast rule, the Watts per pound rule is one that lets you determine the power output needed for your electric rc airplane, to give it the performance that you desire. Peloton doesn’t display this, but’s calculated as FTP/weight-in-kg. Use this page to learn how to convert between kilogram-force meters/second and watts. The correct way to compare is watts per kilogram. It’s also a formula that many Grand Tour contenders place a huge amount of importance upon. It follows therefore that if you have less mass to lug around, you need less power to move it. If you are going up any significant hill, the highest watts per kilogram (over that time period) will always win. Two riders on a 6kg road bike, travelling at 16kph up a 7 per cent gradient. To achieve the best w/kg. Type in your own numbers in the form to convert the units! The first is easy to measure — just hop on some accurate bathroom scales. In fact, remembering that absolute power is still very important, you might be worse off overall. Watts/kilogram (pounds) will be roughly the same. Log in. Wondering what users think would be a good target watts per/kg to qualify for 70.3 worlds and Kona. Watts/kg on the power curve 14 June, 2012 by David Johnstone. However, both riders have had to find a massive 163W extra to overcome the increased aerodynamic resistance experienced at 32kph compared to the resistance at 16kph. A professional cyclist may average 6 watts per kilogram over an hour ride, for instance, while a recreational cyclist will only be able to sustain that level for 1 minutes (or less). If the weight of the bike is 8 kg, this gives an effective W/kg of 160/(50+8) = 2.76 W/kg for the 50 kg rider and 320/(100+8) = 2.96 W/kg for the 100 kg rider. Your five-minute maximum power will be around 10 per cent higher than the 20-minute figure, e.g. However, although it’s 32W less power overall, this translates into a slightly higher power-to-weight ratio of 3.80W/kg. Woman: 125 lbs = 56.8 kg x 3.5 = 198.8 watts at threshold. at 115lbs = 52kg your watts/kg would be 143/52 = 2.75 w/kg. The amount of mass you have to move around — i.e. Going from FTP 260 to FTP 305 was a 4 years grind. Not bad, but not good either, because you're now "less" of a rider in more ways than one. While that’s a good 90 watts more than the likes of me, it’s not all that otherworldly when compared to domestic and international pro cyclists. If you want to succeed in the A category, you’ll need to be able to hit 4.0 w/kg or better. The only reason the 20 min MMP gives a good approximation is because of the over all slope of the MMP curve for all T. The is a significant (usually) inflection point after/at/around 20 min and the differences are much smaller in terms of watts but large in time. a 20-minute figure of 275W would equate to around 260W for an hour. The 70kg rider would only need to average 266W to ride up the same hill at the same speed on the same bike. Sure is a nice advantage when using a high efficiency speaker given that every doubling of power is another +3dB of loudness. If you take .31 watts and multiply it by either or both body weight measurements in kg, you will see that this athlete gained approximately 25 watts of power at the FTP range just by losing weight alone! Here are the categories that they recommend you race based on your FTP data and watts per kilogram. It’s now possible to see your power as watts per a kilogram on the power curve. You'll see this on a hill. To work out your power-to-weight ratio figure, simply divide your maximum power output (in watts) by your body mass in kilograms (kg). Watts/Kg. My best result was just over 18 1/2 mins at an average of 343 watts: I extrapolated (blind guessed!) That’s about the energy two bananas can give me. One super human, like six-time Tour de France stage winner Andre Greipel, can create a charge of 1,900 watts in a single sprint. For example Floyd Landis spent 2 hours @ or above 370 watts throughout stage 17, up to 37 minutes at a time. Words by Andrew Hamilton I have highly regular and routine lifestyle. Strength to weight ratio at FTP = 280 watts divided by 77 kg = 3.64 w/kg, equivalent to a competitive Cat 3 racer. The data revealed that at a power output equal to 3 watts per kilo (W/kg), amateurs produced 37.5% more lactate, but nudge the power up a bit to 3.5W/kg … Photo: Andy Jones. The flatter the terrain, the less power-to-ratio matters and the more absolute power output matters (figure 1). With weight ranging from in the high 130's to the low 150's. Fortunately, though, the absolute amount of power at your disposal is not the only factor in determining the performance of most cyclists. Your output is respectable, but won't win any races among serious riders. A: 4.0 w/kg FTP or higher B: 3.2 w/kg to 4.0 w/kg FTP C:: 2.5 w/kg to 3.2 w/kg FTP D: Under 2.5 w/kg FTP To illustrate this, let’s compare power requirements of a 70kg and 80kg rider riding a 6kg road bike up a hill of seven per cent gradient at 16kph (10mph) in still winds. For example, a rider that weighs 90kg might be able to push out 300 watts for 10 minutes, while a rider who weighs 70kg could hold 270 watts for the same time, yet go faster. Back in 2015 we looked at the Etape to see just how its riders compared to those in the pro peloton. The Watts Calculator takes into account the main variables that effect power output on a bike. WattBike) where you can pedal furiously without needing to slow down for bends, traffic, etc. FTP is the wattage you can stay below and sustain for longer durations, while going above it causes fatigue to occur very quickly. Instead of absolute watt output, we use watts per kilogram (w/kg) to measure wattage in an apples to apples manner. By Zappa Freak, May 13, 2016 in 2-Channel Home Audio. KG 5.5; Reply to this topic; Start new topic; Recommended Posts. About a quarter of my volume is racing. So if you are doing it at 100 watts, your FTP would be around 143watts. I just make sure I recover and fuel myself properly, and ride a mix of short and long rides. If both cyclists weigh 80kg, A will still be faster. Your output is respectable, but won't win any races among serious riders. Calculating your own power-to-weight ratio requires only two measurements: your weight and your maximum sustainable power output. You’ll first want to add your weight, and then you can click on the W/kg button at the top right of the graph and the values are shown as watts per a kilogram. More watts = the ability to perform mork = you’re more fit = that’s a very good thing! By the same token, a plentiful intake of dietary protein is recommended, especially after training. … If you're only able to handle 3 watts per kilogram, you probably don't have a future as a pro cyclist. Watts per kilogram always "works". That’s really good to know and kind of comforting. Despite the fact that Daisy is clearly stronger, Anabelle will be a more efficient cyclist with a power to weight ratio of 8.18 watts per kilo compared with 7.6 watts per kilo for Anabelle. For example Floyd Landis spent 2 hours @ or above 370 watts throughout stage 17, up to 37 minutes at a time. I have never been in a race, nor have I followed any periodized training protocol. Given power is generated within muscle tissue, you might end up reducing your weight but losing some power with it, resulting in minimal improvements in power-to-weight ratio. So over the 40 minutes of my run, that’s a total of 648 kJ of energy. The formula would work as follows: 8 x 3.5 x 73 / 200 = 10.2 calories per minute. Less than 50W/lb - very lightweight / low wing loading slow flyer. The pros can hold around 5-6 W/Kg at threshold. Okay, yeah, women are strong, and fun to watch race, but we do know that just like the difference between a Professional rider and a cat2, a Professional male rider will have a certain watt per Kilogram (w/kg) threshold and an “absolute” wattage sprint that is incrementally higher on average than that of a professional woman. It's a consequence of laws of physics. Anything over 4.25 is domestic pro and it goes up from there. For example at 3.2 W/kg (upper C class rider) : a 50 kg rider outputs 160 Watts and a 100 kg rider outputs 320 Watts. I do about 100-120 miles per week, weigh 78kg, and have an FTP of 280. Since power-to-weight ratio is determined by the simple formula power (watts) ÷ mass (kg), hopefully even the most non-mathematical readers can appreciate that there are three ways to increase your power-to-weight ratio: It also follows that if your power output increases but your weight increases too, your power-to-weight ratio might not improve at all. I train about 6.5 hours in the winter and 8 hours in the summer. As speeds rise, the contribution from aerodynamic resistance becomes proportionately greater. I realize this question is multifactorial and contingent on swim and run capabilities as well; however, what do typical … Many scale (egwarbirds) planes suit this power band. Power-to-weight (specific power) The power-to-weight ratio (specific power) formula for an engine (power plant) is the power generated by the engine divided by the mass. This means this athlete gained .31 watts per kg of body weight at FTP. As more and more data inundates cycling, and more riders have access to individualized data, it has become more important to know what exactly to focus on. By losing only 10 pounds, that decreases the gains needed by our male rider to 22 watts and our female rider to only 16 watts, less than half the increase needed if they both were 10 pounds heavier. On a flat road, there might not be much in it, but head into the hills and it is cyclist B who will be pulling away. This in turn begins to favour absolute power output over power-to-weight. But if A weighs 80kg and B weighs 68kg, cyclist A’s power-to-weight ratio is 3.13W/kg, while B’s is 3.31W/kg. The Zwift C category (next from the bottom) says that you should be able to ride at the level between 2.5 to 3.1 w/kg. So over the 40 minutes of my run, that’s a total of 648 kJ of energy. In simple terms, although much of the riders’ power requirements are a function of body mass (because they’re climbing), there’s an extra, fixed amount of work that has to be done to push the air out of the way (i.e. If you use lbs for weight, formula is FTP/weight-in-lbs*2.205. Let’s say Joe Athlete weighs 165 lb and can hold 270 watts for an hour. This is because accelerating mass or moving mass uphill against the force of gravity requires power. Essentially, the hillier the terrain, the more your power-to-weight ratio matters. This is really where the top athletes separate themselves from the rest. We’ve seen that increasing power, reducing bodyweight or a combination of both can significantly improve your power-to-weight ratio. It's a consequence of laws of physics. ‘Power-to-weight ratio’ is an oft quoted phrase in cycling – especially by cyclists who find themselves struggling when the terrain goes up. It just so happened that a cycling team happened by as I This will depend on your cycling background: Simply riding more miles will boost your power-to-weight ratio. A few years ago, I asked myself, Just what type of rider has it historically taken to be a top level long course triathlete? Raw watts aren’t the most reliable metric of performance, because riders put out varying levels. But A will be faster because he/she will have more power to overcome aerodynamic and frictional drag. And I now weight about 60 kg, which is my race weight. This gives a useful measurement to compare riders of different abilities and weights. However tracking your Watts per Kilogram (W/kg) may produce the biggest results. Increase your power output while also decreasing your weight. My advice for any new cyclist would be: Listen to smart, experienced, good cyclists. See the events here. Power Output to Weight (Watts per Kg) at Lactate Threshold Gender Weight is only relevant in climbing and accelerating. The permissible upper limit for cell phones set by the U.S. Federal Communications Commission (FCC) is 1.6 W/kg of RF radiation. One of my friends is an avid petrol-head who builds and races cars for a living. good watts for KG 5.5. I'd imagine most AG women are under 150 watts depending on how big and what age they are but I'm not sure there is a ton of data around to support that claim other then some one off anecdotal stuff around here or slowtwitch. Regardless of your riding ability, consuming a healthy diet with a minimum of sugary, fatty and processed foods will play a part in improving power-to-weight ratio. With road cycling experience. Good luck in any case – even if you got only part way there it would be very significant. This puts me at 3.6 Watts/kg. in this example, around 295W). Another useful strategy, especially for more accomplished riders, is to perform some regular weight training. He often jokes: “Money can’t buy you happiness, but it can buy you more horsepower — and that’s the same kind of thing.” As cyclists, we can’t buy more power, of course — we have to train our muscles and bodies to produce it, and that’s not easy. The goal was to see what the data says the performance requirements are to be at the highest level. For example, a 50kg rider churning out just 150 watts has the same power-to-weight ratio as a 90kg rider churning out 270. However, absolute power is still important. When I sat down to find the answer, it lead me on a journey that ultimately lead to writing the book, Triathlon 2.0: Data Driven Performance Training . Watts-per-kilo (W/kg) is a rider’s power output for a given effort divided by their weight. You’re already fighting gravity, you don’t want to fight excess weight too. Running at a speed of about 11 km /hr, let’s say I’m producing 3 watts/kg (as above). Watts/kg on the power curve 14 June, 2012 by David Johnstone. 1 kg-m/s is equal to 9.80665 watt. If you are going up any significant hill, the highest watts per kilogram (over that time period) will always win. Now suppose this 90kg rider wants an improved power-to-weight ratio. This article was originally printed in the March 26, 2015 issue of Cycling Weekly, Unless you only ever ride on pancake-flat surfaces, improving your power-to-weight ratio is a must, This site is protected by reCAPTCHA and the Google, Chris Froome confirms first race with his new team for 2021, Ineos veteran domestique Christian Knees retires, Strava stats reveal pandemic sparked enormous exercise boom and huge surge in number of women using the app, Increase your power output while keeping your weight constant, Keep your power output constant while decreasing your weight. It’s now possible to see your power as watts per a kilogram on the power curve. Most people I believe generate between 2 and 3W/kg during long "slow" (i.e. Watts per kg may be a comparative measurement but the real issue at sprint speed is the size of the hole you are poking into the air. Man: 165 lbs = 75 kg x 3.5 = 262 watts at threshold. look at this http://home.trainingpeaks.com/articles/cycling/power-profiling.aspx. Five days later Vincenzo Nibalitook the spoils as the Tour passed through, covering the stage in 4h22m53s at an average speed of 31.5kmh – that’s 11% quicker. Typical values. But how can you best achieve this? Solution for a) What is the power output in watts and horsepower of a 73.0 kg sprinter who accelerates from rest to 10.1 m/s in 3.50 s? Non è possibile visualizzare una descrizione perché il sito non lo consente. Power-to-weight ratio matters because it’s a great predictor of performance. If you use lbs for weight, formula is FTP/weight-in-lbs*2.205. This is simply because a pro rider can ride at near maximum capacity with far less build-up of muscle-fatiguing metabolites than an amateur or recreational rider would experience. My current watts vary from 80 to 150 watts. edit: for tahoe, try to look at w/kg and compare it to some people that have put together a race report if you can. What constitutes a ‘good’ power-to-weight ratio? The figures now become: The rate of ascent overall is still the same and the 70kg rider still requires around 32W less power than the 80kg rider to maintain a speed of 32kph. I upped my volume by 33% this year to 400/week with every 4th week at a lower volume but same intensity, and I’m 49, 68 kg and about 4.8 watts/kg. But I suspect you are asking something like "If I lose weight will my W/kg go up, or should I gain muscle weight to get more watts than kilograms added?" They often will set category boundaries based on your functional threshold power (FTP) in watts per kilogram (w/kg). Peloton doesn’t display this, but’s calculated as FTP/weight-in-kg. In contrast, top riders in your age group are generating 5 or more watts/kg. Dr Andrew Coggan, an internationally acclaimed exercise physiologist, has compiled some typical power-to-weight ratios, which are shown in the Table below. A rider who averages 6.8 watts/kg for 30 minutes may only be able to sustain 6.4 watts/kg for an hour. This gives a useful measurement to compare riders of different abilities and weights. takes the amount of power you produce at various time periods and divides it by how heavy For cyclists who don’t ride on perfectly flat and smooth roads (that’s all of us, then), what matters just as much as your maximum power output is the amount of power that can be produced in relation to bodyweight — power-to-weight ratio — usually expressed in watts per kilogram. With road cycling experience. The second requires a power output measurement. To improve your numbers and make the most of your power meter training, it’s essential to calculate your threshold power. Take two cyclists: Cyclist A can sustain a maximum power output of 250W while Cyclist B can only manage 225W. Zappa Freak 67 Zappa Freak 67 Forum Veteran; Regulars; 67 232 posts; Location: Chicago; Posted May 13, 2016. Here is a simple example that illustrates the effect of weight loss: Starting point Man:175 lbs = ~80 kg x 3.0 watts per kg = 240 watts at threshold Woman: 135 lbs = ~61 kg x 3.0 watts per kg = 183 watts at threshold Power gains needed to reach 3.5 watts per kg Man:175 lb = ~80 kg x 3.5 = 280 watts at threshold Woman: 135 lbs = ~61 x 3.5 = 215 watts at threshold You can see that the mal… Note that rounding errors may occur, so always check the results. higher and further to the right in this table. Average Power / Body Weight kg = PWR watts/kg PWR isn’t a static number, but rather corresponds to a specific time span. Most cyclists will produce the most power at high cadence, when the … At 90 kg, that’s 270 watts – which means 270 J (of energy) per second. The goal was to see what the data says the performance requirements are to be at the highest level. Coach Taylor Thomas outlines why W/kg is so important and how you can improve it. Power-to-weight ratio is a measurement of actual performance of any engine or power source. Figure 1: Terrain and absolute power versus power-to-weight ratio. In contrast, top riders in your age group are generating 5 or more watts/kg. Watts-per-kilo (W/kg) is a rider’s power output for a given effort divided by their weight. This underlines why shedding excess body mass (fat) is so effective at boosting performance — even if your aerobic fitness remains the same. What is a good amount of watts someone that is about 5'5'' should put out? Average recreational cyclists would be about 2.5-3.0 Watts/Kg for FTP. Your email address will not be published. At your weight and speed, given the grade, your output probably averaged about 240 watts, which is 2.42 watts/kg, which places you in the untrained category on the Cycling Peaks WKO scale. Well, this depends on the time period and the level at which you’re riding. Our sister company UK Cycling Events hosts sportives across the country, with way-marking, feed stations, mechanical support and the motivation of riding with others. This includes sessions such as intervals (long and shorter, more intense), hill repeats and some threshold rides. ›› Quick conversion chart of kg-m/s to watt. If he or she sheds 10kg (down to 80kg), power-to-weight ratio jumps from 3.0 to 3.4W/kg — that’s a bigger improvement than staying at the same weight and working on aerobic fitness to increase power output to 300W. 2.75 would be a mid "moderate, cat 4" cyclist. A few years ago, I asked myself, Just what type of rider has it historically taken to be a top level long course triathlete? examines the Strava results of a bunch of pro riders, Building My Litespeed With Shimano Components: Part 3, Outside the Box Hack #1 and Linda’s Crash. For example, an 80kg rider with a maximum sustainable power output of 280 watts has a power-to-weight ratio of 3.5 watts per kilo (commonly abbreviated as 3.5W/kg or 3.5W.kg-1). To measure maximum sustainable aerobic power, ride gently for 10 minutes to make sure you’re thoroughly warmed up. When I sat down to find the answer, it lead me on a journey that ultimately lead to writing the book, Triathlon 2.0: Data Driven Performance Training . Which is why in cycling circles FTP is usually expressed in watts per kg of body weight. Goes up from there 10 per cent lower ( depending on fitness ) than this,.
