On the x-axis is time, and on the y-axis is watts. All power curves are unique, but all are generally higher on the left end and lower towards the right. This is because the amount of power we can produce declines over time.&nbsp;<\/p>\n\n\n\n<div id=\"at-cta\" class=\"cta\">\n    <div class=\"adaptive-training-cta-image\">\n    <\/div>\n    <div class=\"cta__copy\">\n        <p class=\"cta-title\">Adaptive Training<\/p>\n        <p><strong>Get the right workout, every time<\/strong>\n        with training that adapts to&nbsp;you.<\/p>\n        <a href=\"https:\/\/www.trainerroad.com\/adaptive-training\/\" target=\"_blank\" rel=\"noopener\" class=\"btn btn-primary\">Check Out TrainerRoad<\/a>\n    <\/div>\n<\/div>\n\n\n\n<p>A power curve is a valuable tool for analyzing your training, your strengths, and your weaknesses as a cyclist. The TrainerRoad power chart has three different levels so that you can drill into the details of your power. You can view your sprint power (1-30 seconds), endurance (30 seconds-hours), or the entire time frame. You can also set up individual seasons to track your training progress for specific periods of time.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to Use a Power Curve<\/h2>\n\n\n\n<p>The value of a power curve is that it shows you the work you&#8217;ve done. Since it&#8217;s power plotted against time, it gives you a snapshot of your energy systems and a view of your strengths and weaknesses. Let&#8217;s take a look at some examples from a few of my colleagues. While there are several rider profile types, I&#8217;ve just used three. For simplicity, we are looking at their all-time&nbsp;<a rel=\"noreferrer noopener\" target=\"_blank\" href=\"https:\/\/www.trainerroad.com\/blog\/why-you-should-measure-your-power-prs\/\">power PR curves<\/a>.&nbsp;<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Short Power&nbsp;<\/h4>\n\n\n\n<p>I&#8217;m a typical short-power cyclist. I love sprints and quick, hard efforts, but struggle with long threshold work. You can see I can hold a decent amount of power for about 20 seconds, then my curve drops dramatically. After about ten minutes, the power levels off.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"665\" data-src=\"https:\/\/www.trainerroad.com\/blog\/wp-content\/uploads\/2020\/07\/how-to-use-your-power-curve-to-find-your-strengths-and-weaknesses-Jesse-1024x665.png\" alt=\"This is the power curve of a short-power sprinter.

You can go a step further and&nbsp;<a rel=\"noreferrer noopener\" target=\"_blank\" href=\"https:\/\/www.trainerroad.com\/blog\/how-to-use-seasons-for-year-round-cycling-fitness\/\">create custom seasons<\/a>&nbsp;to see how this has changed over time. Once you&#8217;ve got a handle on your strengths and weaknesses, you can decide if you want to change your power curve.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How Trainable is Your Power Curve?<\/h2>\n\n\n\n<p>Your cycling power curve is highly trainable. Regardless of your genetic disposition, you can target specific energy systems by training different muscle fiber types. You can target adaptations within your muscle fibers so that one fiber type is capable of more than one thing.\u00a0 \u00a0<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Muscle Fiber Types<\/h4>\n\n\n\n<p>Skeletal muscles are comprised of three different fibers.&nbsp;<strong>Type I<\/strong>&nbsp;fibers, often called slow-twitch, are powered by aerobic processes and responsible for your endurance. While Type I fibers don&#8217;t produce massive power, they fatigue slowly. There are two kinds of&nbsp;<strong>type II<\/strong>&nbsp;fibers; both are referred to as fast-twitch.&nbsp;<strong>Type IIa<\/strong>, are intermediate fibers. They can use both aerobic and anaerobic metabolism to create energy. Your training profoundly influences type IIa fibers towards aerobic or anaerobic metabolism.&nbsp;<strong>Type IIb fibers&nbsp;<\/strong>are anaerobically fueled and fatigue rapidly. They produce high power, albeit for short durations.&nbsp;<\/p>\n\n\n\n<p>Each muscle fiber type is on a spectrum of power production. They can do all things to some degree. If you do a bunch of Zone 2 up to Sweet Spot, you&#8217;re going to get more aerobic adaptations, especially in type IIa fibers. An athlete who does more anaerobic work will carry more anaerobic adaptations into the intermediate muscle fibers.&nbsp;<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Fueling Your Workouts<\/h4>\n\n\n\n<p>Planning nutrition for your workouts can also affect your power curve. High-intensity, anaerobic work requires sugar to fuel the muscles. That means that if you are looking to increase your peak power and sprint capacity, you&#8217;ll want to<a href=\"https:\/\/www.trainerroad.com\/blog\/how-to-use-carbs-for-maximum-performance\/\"> ensure you have enough carbs<\/a> onboard.&nbsp;<\/p>\n\n\n\n<p>Likewise, if you are using a low-carb diet or fasted rides, remember that your workout options will be limited. These two methods can help you target aerobic adaptations in the form of increased mitochondrial biogenesis and fat utilization. Riding in a low-carb state is going to metabolize amino acids from the muscle. Just remember to replenish with plenty of protein afterward.<\/p>\n\n\n\n<p>Nutrition should center on chasing performance. Fuel the work in a way that will help you reach your goals. It&#8217;s always a good idea to make any changes to your nutrition slowly. That way, your body can adjust accordingly.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Don&#8217;t Limit Yourself<\/h2>\n\n\n\n<p>A power curve doesn&#8217;t define you as an athlete. It only shows the work you&#8217;ve done. Just because you&#8217;re good at one thing doesn&#8217;t mean you can&#8217;t be great at something else. Types of fitness are highly trainable. If you want to change your power curve, do so intentionally to fit your goals. What is a weakness now, can become a strength with the proper training.
