what is a good watts per kg

Different races can have different categories, but most races on Zwift use a similar format. We'll get to this a little bit later in the discussion. Peloton doesn’t display this, but’s calculated as FTP/weight-in-kg. 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). ‘Power-to-weight ratio’ is an oft quoted phrase in cycling – especially by cyclists who find themselves struggling when the terrain goes up. This in turn begins to favour absolute power output over power-to-weight. So if you are doing it at 100 watts, your FTP would be around 143watts. 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). 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 . Wondering what users think would be a good target watts per/kg to qualify for 70.3 worlds and Kona. 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. 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 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. The flatter the terrain, the less power-to-ratio matters and the more absolute power output matters (figure 1). Woman: 125 lbs = 56.8 kg x 3.5 = 198.8 watts at threshold. For example, if you drop from 86 to 82kg and increase your 20-minute power output from 210 to 235W, your power-to-weight ratio increases from 2.4W/kg to a very respectable 2.9W/kg. While improving your aerobic fitness can increase the amount of power your muscles can produce, human physiology means there’s a limit to the gains that can be achieved this way. What constitutes a ‘good’ power-to-weight ratio? Non è possibile visualizzare una descrizione perché il sito non lo consente. 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. With road cycling experience. >>> Cycling training plans: get fitter, ride faster and go further. For example Floyd Landis spent 2 hours @ or above 370 watts throughout stage 17, up to 37 minutes at a time. 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. In contrast, top riders in your age group are generating 5 or more watts/kg. 1 kg-m/s is equal to 9.80665 watt. Your email address will not be published. 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. But how can you best achieve this? look at this http://home.trainingpeaks.com/articles/cycling/power-profiling.aspx. To achieve the best w/kg. Your one-hour maximum sustainable power output will be five to 10 per cent lower (depending on fitness) than this figure, e.g. For example, if rider A weighs 80kg and can sustain 240W, while rider B weighs 70kg and can sustain 210W, they both have a power-to-weight ratio of 3W/kg. This gives a useful measurement to compare riders of different abilities and weights. By Zappa Freak, May 13, 2016 in 2-Channel Home Audio. that downwards to 335 watts for 20 mins which at a weight of 69.4 kilos gives a 20 min w/kg of 4.82 and a 60 min w/kg of 4.47 (I've taken 7.5% off the 20 min figure). The hillier the terrain, the more important power-to-weight becomes. Sure is a nice advantage when using a high efficiency speaker given that every doubling of power is another +3dB of loudness. your sustainable power output); you’ll almost certainly lose a bit of excess body fat in the process. 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. For example, a 50kg rider churning out just 150 watts has the same power-to-weight ratio as a 90kg rider churning out 270. We’ve seen that increasing power, reducing bodyweight or a combination of both can significantly improve your power-to-weight ratio. Running at a speed of about 11 km /hr, let’s say I’m producing 3 watts/kg (as above). 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. A rider who averages 6.8 … The formula would work as follows: 8 x 3.5 x 73 / 200 = 10.2 calories per minute. 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. They often will set category boundaries based on your functional threshold power (FTP) in watts per kilogram (w/kg). #10 VeloFlash , Apr 1, 2003 It’s now possible to see your power as watts per a kilogram on the power curve. 2. Typical values. That’s really good to know and kind of comforting. Peloton doesn’t display this, but’s calculated as FTP/weight-in-kg. Watts-per-kilo (W/kg) is a rider’s power output for a given effort divided by their weight. 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. what should be my average watts basing on my stats. Good luck in any case – even if you got only part way there it would be very significant. This result is your watts per kilogram ratio. To measure maximum sustainable aerobic power, ride gently for 10 minutes to make sure you’re thoroughly warmed up. Unlike muscle tissue, excess body fat blunts power-to-weight ratio and contributes nothing to power output. Anything over 4.25 is domestic pro and it goes up from there. One of my friends is an avid petrol-head who builds and races cars for a living. The permissible upper limit for cell phones set by the U.S. Federal Communications Commission (FCC) is 1.6 W/kg of RF radiation. 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. Most cyclists will produce the most power at high cadence, when the … This puts me at 3.6 Watts/kg. 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. 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. To work out your power-to-weight ratio figure, simply divide your maximum power output (in watts) by your body mass in kilograms (kg). The goal was to see what the data says the performance requirements are to be at the highest level. Most people I believe generate between 2 and 3W/kg during long "slow" (i.e. Power-to-weight ratio is a measurement of actual performance of any engine or power source. 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. What’s more intriguing is that compared to amateur and recreational riders, the typical one-hour power-to-weight ratio of a pro rider is only fractionally lower than the 20-minute figure. Your output is respectable, but won't win any races among serious riders. 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. in this example, around 295W). >>> When’s the best time to train? I have highly regular and routine lifestyle. Not bad, but not good either, because you're now "less" of a rider in more ways than one. The flatter the terrain, the more important absolute power becomes. Going from FTP 260 to FTP 305 was a 4 years grind. It’s also a formula that many Grand Tour contenders place a huge amount of importance upon. Dr Andrew Coggan, an internationally acclaimed exercise physiologist, has compiled some typical power-to-weight ratios, which are shown in the Table below. Zappa Freak 67 Zappa Freak 67 Forum Veteran; Regulars; 67 232 posts; Location: Chicago; Posted May 13, 2016. This includes sessions such as intervals (long and shorter, more intense), hill repeats and some threshold rides. Words by Andrew Hamilton 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. Looking at Table 1, notice how power-to-weight ratios rise as power output rises and bodyweight falls — i.e. If both cyclists weigh 80kg, A will still be faster. 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. You need to be a bit more focused than simply adding more miles. My IM threshold is 3.35W/kg, but there's a bit more to IM bike racing than watts per kilo if you really want a fast bike split, swim faster, you'll come out with faster riders, and you'll do a lot less work on the bike because you will just sit 7m behind the guy in front and do nothing but sit there. To improve your numbers and make the most of your power meter training, it’s essential to calculate your threshold power. Protein is needed for recovery and repair after training, and studies show that higher intakes of protein can help prevent muscle mass loss when training volumes are high. Third, by charting W/Kg at different time durations, you can get a good idea of the type of events you can excel at. About a quarter of my volume is racing. 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. 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. I realize this question is multifactorial and contingent on swim and run capabilities as well; however, what do typical … a 20-minute figure of 275W would equate to around 260W for an hour. It just so happened that a cycling team happened by as I 50 to 80 W/lb - light powered gliders, basic park flyers and trainers, classic biplanes and vintage ('Old Timer') type planes. 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. 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 … What is a good amount of watts someone that is about 5'5'' should put out? Weight is only relevant in climbing and accelerating. good watts for KG 5.5. Two riders on a 6kg road bike, travelling at 16kph up a 7 per cent gradient. Let’s say Joe Athlete weighs 165 lb and can hold 270 watts for an hour. The amount of mass you have to move around — i.e. I'm curious if i put out more or less than the avg. Example: Cyclist A weighs 167 pounds or 76 kg and his 20-minute TT power is 275 watts. at 115lbs = 52kg your watts/kg would be 143/52 = 2.75 w/kg. Weight in this context is a colloquial term for mass.To see this, note that what an engineer means by the "power to weight ratio" of an electric motor is not infinite in a zero gravity environment. The goal was to see what the data says the performance requirements are to be at the highest level. Raw watts aren’t the most reliable metric of performance, because riders put out varying levels. Watts = the ability to perform work, as fitness improves. Motivate yourself with an event. A rider who averages 6.8 watts/kg for 30 minutes may only be able to sustain 6.4 watts/kg for an hour. 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? The correct way to compare is watts per kilogram. Instead of absolute watt output, we use watts per kilogram (w/kg) to measure wattage in an apples to apples manner. And your elite pro cyclists will be averaging over 300W at 60Kg (5W/Kg… Here are some Watts per pound values that should put you in the right ballpark for your particular plane... 1. The first rider across the line in the amateur sportive was France’s Jeremy Bescond in 4h52m44s. People who race regularly may be 3.0-3.75. Which is why in cycling circles FTP is usually expressed in watts per kg of body weight. Calculating your own power-to-weight ratio requires only two measurements: your weight and your maximum sustainable power output. That’s it, hope that help. We can draw another conclusion: when power-to-weight ratios are identical, the rider with the highest … 4. If you use lbs for weight, formula is FTP/weight-in-lbs*2.205. overcoming aerodynamic resistance), which is the same for both riders. More watts = the ability to perform mork = you’re more fit = that’s a very good thing! Photo: Andy Jones. Notice too how any given power-to-weight ratio (we’ve highlighted 3W/kg) can be achieved at much lower absolute power outputs when the rider’s mass is low. 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. KG 5.5; Reply to this topic; Start new topic; Recommended Posts. Let your body clock decide. So over the 40 minutes of my run, that’s a total of 648 kJ of energy. On a perfectly flat, smooth indoor track (where gravity is not an issue) we can confidently predict that A will be faster than B. My current watts vary from 80 to 150 watts. However, absolute power is still important. 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). With weight ranging from in the high 130's to the low 150's. Watts/kg on the power curve 14 June, 2012 by David Johnstone. 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 . 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. As to your testing: a VO2max of 62.6ml/kg/min at 69.4kg (4.34l/min). 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. Of course Nibali had the assistance of his team and other riders around him (al… If you are going up any significant hill, the highest watts per kilogram (over that time period) will always win. Watts-per-kilo (W/kg) is a rider’s power output for a given effort divided by their weight. Take a couple of minutes’ rest, then ride as hard as you possibly can for 20 minutes and record your average power output figure in watts. This explains why power-to-weight ratio becomes especially important when climbing. FTP is the wattage you can stay below and sustain for longer durations, while going above it causes fatigue to occur very quickly. to calculate NP 1) starting at T 30 s, calculate a 30 second rolling average for power higher and further to the right in this table. A better option is to include some specific training to boost maximal power output. 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. So over the 40 minutes of my run, that’s a total of 648 kJ of energy. To work out your power-to-weight ratio figure, simply divide your maximum power output (in watts) by your body mass in kilograms (kg). 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… 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. 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. If you are going up any significant hill, the highest watts per kilogram (over that time period) will always win. That’s about the energy two bananas can give me. You get above 3.75-4.25 and those are local elite racers. To illustrate this, let’s now suppose that the riders are travelling twice as fast (32kph) but the gradient is half as steep (3.5 per cent). 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. takes years and years of dedicated practice, and of course good genetics doesn’t hurt. Power Output to Weight (Watts per Kg) at Lactate Threshold Gender KG = your body composition. Another useful strategy, especially for more accomplished riders, is to perform some regular weight training. But my BMI is over 25 and I have a good sized pot belly. In contrast, top riders in your age group are generating 5 or more 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?" What matters in cycling is the number of watts per kilogram, which takes into account a rider’s weight and size. 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. absolute power will be faster. At 90 kg, that’s 270 watts – which means 270 J (of energy) per second. 2.75 would be a mid "moderate, cat 4" cyclist. It's a consequence of laws of physics. This is really where the top athletes separate themselves from the rest. I did a set of 20 last night on an overpass. Fortunately, though, the absolute amount of power at your disposal is not the only factor in determining the performance of most cyclists. Essentially, the hillier the terrain, the more your power-to-weight ratio matters. Putting in more miles will not only boost your level of aerobic fitness (i.e. My advice for any new cyclist would be: Listen to smart, experienced, good cyclists. 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. The pros can hold around 5-6 W/Kg at threshold. By the same token, a plentiful intake of dietary protein is recommended, especially after training. That’s about the energy two bananas can give me. I do about 100-120 miles per week, weigh 78kg, and have an FTP of 280. You've dropped from the magic 4.00 w/kg to 3.78. 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. 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. 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. In fact, remembering that absolute power is still very important, you might be worse off overall. Watts per kilogram always "works". And I now weight about 60 kg, which is my race weight. 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. The first is easy to measure — just hop on some accurate bathroom scales. The Watts Calculator takes into account the main variables that effect power output on a bike. It’s now possible to see your power as watts per a kilogram on the power curve. A few years ago, I asked myself, Just what type of rider has it historically taken to be a top level long course triathlete? Here are the categories that they recommend you race based on your FTP data and watts per kilogram. 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. Less than 50W/lb - very lightweight / low wing loading slow flyer. To do this, you’ll need to use a bike with a reliable power meter fitted (SRM, Powertap, etc) or better still, a stationary bike with accurate power metering (e.g. Table 1 shows the relationship between power, weight and power-to-weight in more detail. As speeds rise, the contribution from aerodynamic resistance becomes proportionately greater. Figure 1: Terrain and absolute power versus power-to-weight ratio. As we saw earlier, shifting mass uphill means that you have to work against the force of gravity. Photo: Andy Jones. 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.
