According to a November 2017 article published by Arab Journal of Nutrition and Exercise, body composition goals vary by sport.While adding muscle mass helps increase your strength-to-weight ratio when you are a weight- or powerlifter, you don't want to add too much excess muscle when you're an endurance athlete or a gymnast The oft-referenced power-to-weight ratio has always made more sense to me when expressed as weight-to-power, where I can see exactly how many pounds each horsepower (or pound-foot of torque) is. A couple weeks ago I posted about calculating your power-to-weight ratio, how to do it, and why it's important to monitor. In that post, we only talked about your power-to-weight ratio relative to your functional threshold power (or FTP), what we didn't talk about was calculating this relative to other performance benchmarks If you are used to measuring your weight in pounds (lb.), then take your weight in pounds and divide by 2.2- and that will be your weight in kilograms. Then take your average power for a 60-minute all-out effort and divide that by your weight in kilograms. This result is your watts per kilogram ratio. Let's put this math to work in an example
Power to weight ratio is calculated quite simply - you take the amount of power you output in watts and divide it by the amount you weigh in kilos. Always a fan of a little anecdote, here is one to explain the concept of power to weight ratio: We have two cyclists- Annabelle and Daisy. Anabelle is super petite and weighs just 55kgs and has a.

For example, a 125lb/56kg rider with a power output of 195 watts, is riding at 3.5 w/kg. Don't feel like doing the math to find your number? Zwift automatically calculates this for you in game
This puts Nebens power-to-weight ratio literally off the charts and shows why the then-41-year-old was able to become the individual time trial world champion later that year If the climber can put out 350 watts over the course of they climb then their power to weight ratio is 6.1w/kg, whereas the sprinter can produce 440 watts but has a lower power to weight ratio of. The power/weight ratio can be expressed as follows: 0.5: 1 means that the thrust is half the weight, with this in mind, for gliders or light and slow-flying model aircraft, a ratio of between 0.3: 1 to 0.4: 1 on trainer models from 0.5: 1 to 0.8: 1 and on fast models from 0.8: 1 onwards
This is because the 90kg rider is holding 3.3 W/kg whilst the 70kg rideris pushing out 3.85 W/kg and a higher power-to-weight ratio corresponds to a greater speed, particularly uphill In the chart you can see the peak horsepower, the weight of the car, the power-to-weight ratio (horsepower divided by the weight), the number of seconds the car takes to accelerate from zero to 60 mph, and the price A power to weight ratio of 5-6 would put you in the range of a Category 1 elite professional (according to Andy Coggan's power profiling chart). So what this means for any cyclist is that the greater your strength compared to your weight, the faster you are going to be on the bike With a dry weight of 162kg (357 lbs), the Panigale R has a power to weight ratio of 1.209. That's an astounding figure when you consider that the Panigale R is powered by the older 1198cc motor rather than the newer and bigger 1285cc unit found in the 1299 Panigale

What's a good power-to-weight ratio? Well, higher is better. I'm a pretty big rider at 92kg, and my FTP is around 315W, giving me a power-to-weight ratio of about 3.4W/kg. That's fairly average. I'm a good enough rider to make it off the bottom rung of the racing ladder into the third cats, but I'm not exactly pulling up any trees there This entry was posted on June 2, 2008 at 4:48 PM and is filed under Uncategorized.You can follow any responses to this entry through the RSS 2.0 feed. You can skip to the end and leave a response A lot of numbers get thrown around with regards to power to weight ratios. The first thing to highlight is the time period you are talking about when quoting a power to weight ratio. For example.
F/W is the thrust to weight ratio and it is directly proportional to the acceleration of the aircraft. An aircraft with a high thrust to weight ratio has high acceleration. For most flight conditions, an aircraft with a high thrust to weight ratio will also have a high value of excess thrust. High excess thrust results in a high rate of climb. Subject: Power weight ratio chart..is there one for women? I can't seemed to find a chart for women riders. I just got a power tap and have my ftp to go by but i would like to know what is my ratio. anybody know? Nathalie. My Race Log. running2far. 2008-05-03 2:45 PM. in reply to: #1379858 The highest power to weight ratio measured in competition was produced by the former Italian cycling-sport pro Marco Pantani who conquered the legendary ascent of L'Alpe d'Huez in 1997 with 7.2 watts/kg in 37:35 minutes. The standards for racing cyclists are also divided into different categories In general, the greater the weight-to-power ratio the more fuel-efficient, but the less 'responsive' will the vehicle be. Most engines work at their greatest efficiency when they are operating near their maximum power. If you must have a vehicle that will get from 0 to 100km/hr in a few seconds you need one with a low weight-to-power ratio Re: Boat weight to HP ratio ? the Coast Guard guidelines is the best way to go. That being said, another way to get the ESTIMATED MINIMUM HP required to plane a boat. This is assuming your weight is accurate, and you are dealing with a flat-bottomed boat in still water. It is very simple. Take your boat weight and divide by 50
Weight was holding strong at around 3,250 lbs with the SN bodies until 2005 when the 5th gen arrived. Luckily, it also brought the 4.6L V8 with it, making 300hp. This helped it lower it's weight to horsepower ratio below 12 for the first time since 1972. The last big jump in weight we see is in 2011 with the introduction of the Coyote engine It's also a calculation that most Grand Tour teams place huge importance upon. Power-to-weight ratio is the maximum power output that can be produced in relation to body weight. Power-to-weight ratio matters because it helps predict performance. For example: Cyclist 1 can sustain a power output of 300W while Cyclist 2 can only manage 250W ET and MPH in Quarter Calculator: Wallace Racing BACK to Calculators.
