The best way to calculate your LTHR is to do a 30-minute all out time trial by yourself . Use a heart rate monitor to check your average heart rate for the last 20 minutes of your time trial and that will be your LTHR Make sure you do not slouch in the first 10 minutes though, it is all out for the full 30 minutes!
What is a good average wattage cycling?
No exact watt number is appropriate for all riders. Generally speaking, a beginner cyclist may average around 75–100 watts in a 1-hour workout . A fit participant will average more than 100 watts, and pro cyclists can reach 400 watts per hour.
How do you calculate power output on a cycle ergometer?
To calculate the power output, you will have to convert kpm/min to Newtons per minute (N/min) P = (720 kmp/min x 9.81) / 60 seconds = 118 W. This can easily be simplified and approximated as: Power output = Braking load x RPM P = 2 kp x 60 RPM = 120 W.
How do I calculate power?
Power is equal to work divided by time .
In this example, P = 9000 J / 60 s = 150 W . You can also use our power calculator to find work – simply insert the values of power and time.
Can you calculate power from speed and cadence?
They don't actually measure your power output, but based on known power curves of the trainer at given speed/cadence they run through some formulas to give you a number as you spin away on the trainer .
How are power zones calculated?
Power zones are calculated based on percentage of your Functional Threshold Power (FTP) and are commonly used for workout targets in order to give a range of intensity for an interval.
How does strava calculate power zones?
Strava looks at your Weighted Average Power for the ride and compares it to your FTP . For example, if your Weighted Average Power is 225W and your FTP is 300W, then your Intensity would be at 75%. Power Curve shows your best average power for time periods of one second up to the length of your ride.
What are the power zones cycling?
Power Zones are defined as a percentage of your Functional Threshold Power (FTP) . We use the Ramp Test to find your FTP, then calculate your zones and automatically scale your workouts to your measured fitness. In practice, FTP represents the level of cycling intensity you could theoretically maintain for an hour.
How many watts is Peter Sagan?
Peter Sagan, racing at approximately 75kg, crossed the line in 2:26:00 with an average power of over 247 watts . His average cadence was 73rpm with an average speed of 39kph. The short stage contained over 1,250 meters (4,100 ft) of climbing and required around 2,000 kilocalories.
What is a cat 4 cyclist?
4. For the men to move up to Cat. 4, the most traveled route is to complete 10 massed-start races permitted by USA Cycling . The races must be at least 15 miles long if it's a road race and 10 miles long if it's a criterium. Once a rider is Cat.
Is Strava watts accurate?
the virtual watts from Strava are not accurate enough to worry about . If you want to get a feel for improvement, look at speed over the same course over time. There will be variance in that data due to wind etc, but it's going to be a much better indication of improvement.
How do you calculate Watts from volts and amps?
- The number of watts is equal to amps multiplied by volts. That's it! ...
- For example, if the current is 3 amps (3A) and the voltage is 110V, you multiply 3 by 110, to get 330W (watts). The formula is P=3A X 110V = 330 W (with P standing for power).
- This is why watts are sometimes called volt-amps.
What's the difference between calculating work and calculating power?
Work is defined as the process of energy transfer to the motion of an object through the application of force. This is usually represented as the product of force and displacement. The SI unit of work is Joule. Power is defined as the amount of energy transferred in unit time.
How do you calculate power in KGM min?
- For power outputs between 150-750 kgm.min or 25-125 watts:
- VO2= (3 x kgm) / kg + 3.5.
- Or.
- VO2= (18 x watts) / kg + 3.5.
How do you calculate input power?
- Electrical power is calculated by multiplying voltage (in volts) by current (in amps).
- If a transformer is 100% efficient, then the input power will equal the output power. ...
- V P is input (primary) voltage.
- I p is input (primary) current.
- V s is output (secondary) voltage.
How do you calculate energy from power?
Formula for calculating power from electrical energy
The formula that links energy and power is: Energy = Power x Time . The unit of energy is the joule, the unit of power is the watt, and the unit of time is the second.
How do you calculate power from resistance and cadence?
Output ~= (Cadence – 35) * (Resistance/100)2.5 * 24 . Output is essentially the scaled result of cadence times a positively-power-scaled resistance factor. At a constant cadence, as you add more and more resistance you get back larger and larger increments of output increase.
What power zone is base training?
Training Zone 2 / Endurance / Base: 56 – 75% of Threshold
Being able to ride 2-6 hours in Zone 2 is the first step in an athlete's training for being able to compete in races or events of similar duration. By riding in zone 2, athletes can train their body to burn fat in preference of muscle glycogen.
How do I check my VO2max on Strava?
- Link HRV4Training to Strava from Settings.
- Go running using a HR monitor, at least twice per week.
- Once we have 12 Strava trainings including HR data in the past 6 weeks, HRV4Training will be able to estimate your VO2max. You can check your VO2max under Insights in the app, as shown below:
What is a good FTP for a man?
FTP in watts per kilogram for males
48.6% of people have an FTP below 3.4W/kg . 42.1% of people have an FTP of 3.6W/kg or more. 9.3% of people have an FTP between 3.4W/kg and 3.6W/kg.
What is weighted average power in cycling?
The idea behind Weighted Average Power is that average power alone doesn't tell the whole story of a ride . For example, if you do a three-hour ride at a constant 150 watts, this (depending on how powerful you are, of course) may be a gentle ride and not leave you too tired.
