Is it theoretical power and maximum, knowing that depending on the mechanism that will recover (transform) this energy, for example a bike, we will exploit more or less these 300 watts? (which depend on the friction forces and the efficiency of the system, ...)
300 Watts is very, very optimistic!
The power of an average cyclist is about 100 watts *, effort that can be delivered for about 2 hours for a person with the correct physical condition.
And after 2 hours at this power, the rest is not stolen!
300 Watts corresponds to the effort of a top athlete, it is considered that beyond 400 Watts there is suspicion of doping over prolonged efforts ...
By using another mechanical system that makes better use of all muscular strengths, and not just calves and legs, will the energy delivered be higher than the 300 watts admitted?
No, because the energy will simply be better distributed among the different muscle groups, you will be able to glean some Watt at best
s with an optimization of your position.
In fact, the more you request muscular groups and the more the heart must provide a major effort to feed the last ones, the fact of making work more muscles will cause an increase in the heart rate until you reach your goal.
maximum aerobic speed if you continue your effort to exhaustion.
Everything depends on your V02 max.
* That is 40 million cyclists to produce the power of an average nuclear power plant! Taking into account the load factor (fatigue, sleep meal, RTT, illness), it would be necessary to pedal the whole EU to replace four reactors!
