- 1. Why Train with Power? Why Train with Power? Bob McEnaney www.totalcyclingperformance.com Woodbury, MN
- 3. Contributors Allen Lim, PhD Director of Education-Saris Cycling Group, Coach-Garmin-Slipstream Angie Sturtevant Director of Fitness-Saris Cycling Group, Owner-Specialists in Sports Performance
- 5. Cycling Power is Dynamic Torque x Cadence or Angular Velocity Push Harder Pedal Faster or Power at the Hub All the Forces Resisting Movement x Velocity For Bike & Rider
- 7. Points of Reference For his World Hour Record in 1996, Chris Boardman averaged an estimated 442 W In setting a new women’s record of 54 minutes 2 seconds at the 2002 Mt. Washington (NH) Hillclimb, Geneviève Jeanson averaged an estimated 278 W (5.56 W/kg) Lance Armstong’s time of 38 minutes 1 second in climbing L’Alpe d’Huez during the 2001 Tour de France produced an estimate of 6.5 W/kg The best male match sprinters have hit 23 W/kg, females ~20 W/kg
- 9. Power is Energy 1 Kcal = 4.186 Kjoules Most humans are about 22-25% efficient on a bike, meaning only 22-25% of the kcals you burn actually goes into the bike, therefore: 4.186 Kjoules x .22 = 1 Kjoules Video

- MEASURING POWER Dictionary Definition Influence, muscle, force, energy, potential, intensity Opposite is weakness Physics Quantity which has to do with the rate work is done The energy produced or work done in a given time frame Sometimes done quickly & other times done slowly People can do the same work, yet in more/less time than another Same work in shorter period of time = greater power More work in same period of time = greater power

- The Power Tap works by measuring the amount of force at the rear hub using strain gauges embedded in the hub and by measuring the speed of the hub.
- The practical perspective here is understanding how much you should eat when on a training ride or when racing. Also to understand how much you should after an event or workout.
