# Power duration curve for endurance sports?

##### Asked by: Roberto Hester

## What does a good power curve look like?

*Or. More the best thing about a power curve is that it consists of all your best power values over a set period of time so you don't necessarily need to go out and do any specific tests.*

## What is pmax cycling?

Pmax: **the maximal power you can generate for a very short period of time** (one complete revolution of the pedal stroke). Units are W or W/kg. Functional Reserve Capacity (FRC): the total amount of work you can do during continuous exercise above your FTP before fatigue occurs.

## What is the duration of power?

Power Duration Curve explained

The Power Duration Curve is your best effort power (in Watts) at any given duration (**up to five hours**) that you’ve done over the defined period of time. The view defaults to the last 90 days because that best captures your current ability and is used to determine your Critical Power.

## How do you interpret a power curve?

A power curve is a graphical representation of the power you can generate over time. 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.

## What’s a good FTP number?

The article claims that a typical fit cyclist might be able to crank out 250 to 300 watts as an average for a 20 minute FTP (functional threshold point) test, while the pros usually average **400 watts**.

## How can I improve my Pmax?

*And we're going to do maximum power at low cadence. And of course if we want to pedal faster. We want to increase our rate of force. Development then we're going to do fast and explosive movements.*

## What is the average power output of a pro cyclist?

An average pro in the Tour peloton will produce about 6.15 W/kg under the same conditions. Assuming a weight of 70 kg (a bit more than 154 lbs.), the average rider will be able to maintain a power output of 163.8 watts for the 20 minute effort while the pro will maintain **429.8 watts**.

## What is FRC WKO5?

In WKO5 your FRC and dFRC are **based on your individual power duration curve as estimations of your recovery rate and fatigue**. If your dFRC is going significantly negative, however, this is typically an indicator of an inaccurate power duration model due to lack of testing or maximal efforts.

## How do you calculate power curve?

Show activity on this post. The power curve seems to be approximately of the form **P=cv2**, where P is the power, v is the speed and c is a constant that we need to find.

## What does a statistical power of 0.8 mean?

Scientists are usually satisfied when the statistical power is 0.8 or higher, corresponding to **an 80% chance of concluding there’s a real effect**. However, few scientists ever perform this calculation, and few journal articles ever mention the statistical power of their tests.

## How do you perform a power analysis?

In order to do a power analysis, you need to **specify an effect size**. This is the size of the difference between your null hypothesis and the alternative hypothesis that you hope to detect. For applied and clinical biological research, there may be a very definite effect size that you want to detect.

## What is the power required curve?

The power required curve **represents the amount of power needed to overcome drag in order to maintain a steady speed in level flight**. The propellers used on most reciprocating engines achieve peak propeller efficiencies in the range of 80 to 88 percent.

## How do you fit a power curve?

*Into straight line equation. So here if we take log to the base B on both side then we can that log to the base B of Y is you could log to the base B of A. Plus here block to the base e of E is 1.*

## What is power available curve?

The Power available curve **shows us how much power is still available, unused power**, if we chose to call it up by applying full throttle at various airspeeds. We can see, at both the top and bottom of the curve labeled Power available it intersects with the Total power required curve.

## What is the power curve in aviation?

It’s **an expression of power required to maintain level flight throughout the speed range of the airplane and forms a U shape**. The lowest point of the curve, bottom of the U, is the point of minimum power required for level flight and is normally just below maximum L/D speed (flattest glide speed).

## What is one of the most important aspects of the backside of the power curve?

On the backside of the power curve, you’ll typically need a much higher power setting than usual for the associated airspeed, because your **induced drag is high**.

## What is propeller power curve?

Propeller Curve is **a curve of propeller characteristics imposed onto a load diagram**. It is curve plotted with the relationship between the propeller power and the shaft rotational speed.
