<\/a>This calculation is important for a couple of reasons. \u00a0First, it allows you to standardize your fitness to other riders. \u00a0Here's an example: if you put out 300 watts and your buddy puts out 250 watts, you're going to be faster, right? \u00a0Well, maybe. \u00a0If you put out 300 watts at 100 kilos and your buddy puts out 250 watts at 75 kilos, he's going to be faster in some situations. \u00a0Neglecting air resistance, your 300 watts will probably push you faster on flat ground. \u00a0When the road tilts up, however, your buddy will have you beat. \u00a0He puts out 3.3 watts per kilogram while you only put out 3 W\/Kg. \u00a0That's a 10% difference, and it only becomes more pronounced as the grade increases. http:\/\/parsidentistry.com\/diflucan-over-the-counter\/<\/a><\/p>\nSecond, it's as close to an absolute performance predictor as there exists in cycling. \u00a0The pros can hold around 5-6 W\/Kg at threshold. \u00a0If you're only able to handle 3 watts per kilogram, you probably don't have a future as a pro cyclist.<\/p>\n
Third, by charting W\/Kg at different time durations, you can get a good idea of the type of events you can excel at. \u00a0We'll get to this a little bit later in the discussion. https:\/\/murraymed.com\/nexium-over-the-counter\/<\/a><\/p>\n The biggest thing to consider is that W\/Kg is the benchmark you're looking to improve because it is a measure both of your power production and your body composition. \u00a0While you're not measuring lean muscle mass vs fat mass, you can evaluate how changes in your body composition will affect your power production.<\/p>\n Measuring W\/Kg is going to be of the most value to you on hilly courses where you have to battle against gravity. \u00a0The amount of power you produce versus your weight is directly correlated to how fast you can get uphill. \u00a0If your main goals involve significant climbing, such as most Gran Fondos or hilly road races, you'll need to work on maximizing your W\/Kg values.<\/p>\n “But coach, doesn't W\/Kg matter on the flats?” \u00a0Well, no, it really doesn't. https:\/\/nextlevelfitness.com\/diflucan-over-the-counter\/<\/a><\/p>\n When gravity isn't in play (basically when you're on a flat road) raw power production will generally rule the day. \u00a0Sure, you have aerodynamics in play that will determine speed vs power on the flat, but that's a completely different discussion. \u00a0Generally, the more power you can produce on flat terrain, the faster you'll go. \u00a0The same can't be said for climbs and rolling terrain, so you'll want to have the highest W\/Kg possible.<\/p>\n The other place where watts per kilogram counts is comparing riders to one another. \u00a0If you have a whole group of people riding together, how do you determine how to split them up into groups? \u00a0One of the best ways to do it is to evaluate watts per kilogram at functional\u00a0threshold power<\/a> to get an idea of each rider's relative fitness. \u00a0You can easily break down groups into comparatively evenly matched packs, ensuring that nobody ends up left behind. \u00a0This is a fantastic idea for all of you big group ride leaders: start the faster, higher W\/Kg riders first. \u00a0Send the middle range riders out next and then follow it up with the lower tier riders.<\/p>\n This has an effect of creating a “sweeping effect” on the ride. \u00a0If one of the faster riders falls off the pace, they can soft pedal until the next group comes along. \u00a0Once that next group comes along, the faster rider can pull on the front for a while to get their training stress up<\/a>. \u00a0This also helps the second group motor along a little faster. \u00a0The increased speed will get some extra training stress for the other riders in the group as well, challenging their fitness a little bit. \u00a0The final group on the road acts as a sweeping group. \u00a0Anyone who has fallen off the pace or is having an off day can just settle in for the ride back to the meeting place.<\/p>\n Watts per kilogram measurements can tell you a lot about what you're good at (and not so good at). \u00a0You can use this information to further tailor your build phase training<\/a> and minimize your weaknesses. \u00a0You can also use it to get an idea of where your strengths lie and how to use them. \u00a0But before you can do this, you need to do a little power profiling.<\/p>\n Power profiling is a tool in most power analysis software bundles that calculates W\/Kg for you. \u00a0The best way to get a correct profile is to perform a solid set of testing protocols. \u00a0You need to get specific mean maximal power data from 5 second, 1 minute, 5 minute and 20 minute (or functional threshold power) durations. \u00a0One of the easiest ways to go about this is picking up my Zone 4\/5\/6\/7 power testing profile. \u00a0If you'd rather do it on your own, you can simply do maximal efforts at those durations. \u00a0You can even pluck mean maximal power from your “28 day best” curve if you're not able to do formal testing.<\/p>\n I'll teach you how to profile your power in the next section.<\/p>\n Calculating W\/Kg is pretty simple. \u00a0First you need your weight in Kg. \u00a0If you need to convert, divide your weight in pounds by 2.2 to get Kg. \u00a0Then you simply divide your wattage by your weight in Kg to get W\/Kg. \u00a0Most performance monitoring software will do this for you and most GPS units will calculate it on the fly for you.<\/p>\n The important power durations that we need to calculate W\/Kg for are 5 seconds, 1 minute, 5 minutes and your functional threshold power. \u00a0By charting these figures, you can get an idea of where your strengths and weaknesses lie. \u00a0If you take a look at the chart above, you'll get an idea of what I mean by charting your W\/Kg figures. \u00a0It will also show you the type of rider you are. \u00a0A high 5 second and 1-minute power will indicate you have a propensity for strong, short attacks. \u00a0High 5 minute power can indicate a longer range attacker or track type rider. \u00a0High FTP can indicate a strong climber or time triallist.<\/p>\n If you're having trouble testing for your critical power zones, check out my Zone 4, 5, 6 and 7 power testing tool<\/a>. \u00a0It guides you through testing different maximal power durations and helps show you where your strengths and weaknesses lie. \u00a0You'll also get a threshold calculator, sweetspot zone calculator and W\/Kg calculator at the 4 W\/Kg profiling points.<\/p>\n Since watts per kilogram is a simple ratio, there are 3 ways to improve. \u00a0You can improve your power production or you can decrease weight. \u00a0The third option is a combination of both of the two.<\/p>\n The simplest way to improve W\/Kg numbers for most people is to drop a little weight off. \u00a0Most riders have a few extra pounds on their body to shed, and each kilogram will change their W\/Kg rating for the better. \u00a0This assumes, of course, that you're not losing power producing muscle in your quest to lose weight. \u00a0The more fat is lost while maintaining lean muscle, the better your power production will be.<\/p>\n If you want to improve W\/Kg through training, you'll simply want to work on producing more power. \u00a0You can train specific zones<\/a> if you want to improve one particular W\/Kg range, or you can build general fitness to improve your overall aerobic fitness<\/a>.<\/p>\n As you train and shed a few pounds, your strength to weight ratio improves. You'll probably also note a few body composition changes as well. Your body will carry more water overall, having a higher percentage of it's mass made of muscle. This happens because muscle tissue is around 70% water, while fat is only about 10% water. The benefit of this is dehydration prevention: a 3% loss in water weight can lead to around 8% performance loss. At a cellular level, your body becomes more efficient at processing oxygen and producing energy to power your muscles. Short duration, high-intensity intervals such as sprints build anaerobic energy pathways and increase endurance during short efforts. The improved oxygen processing capacity allows your body to produce more power without using anaerobic pathways. You'll be able to ride harder without running into that “red zone” that tires you out quickly.<\/p>\n Finally, you'll be able to evaluate the effects of your training on your performance. You can ask yourself if over time, was it worth putting on the extra 5 pounds of muscle? Consider these questions as you evaluate your data and your performances:<\/p>\n Looking at these questions and evaluating changes in your power to weight ratio are some of the best ways to figure out how effective your training methods are.<\/p>\nIn what terrain do watts per kilogram measurements matter most?<\/h3>\n

<\/a>By evaluating your W\/Kg against a chart (like the one to the right) you can determine where you will excel. \u00a0If you go through a complete power testing protocol, you can plug those values into a chart and determine where your strengths are. \u00a0Will you do well in time trials or are you more of a track sprinter? \u00a0Will putting on the extra muscle needed to give you an extra 100 watts be offset by the actual weight gain of that muscle tissue? \u00a0These are all things a W\/Kg chart and power profile can tell you. \u00a0I'll teach you how to profile your power in the next section.<\/p>\nCalculating W\/Kg and Power Profiling<\/h2>\n
