No...the total/overall force(effect of force over time...impulse) is given by N*s...NOT by N.
The more N means greater peak force as they also state by themselves("Concentric strength(N) = Fmax
in the push")
Yes...but you must also normalize the raw EMG data in order to integrate.Check the paragraph " materials and methods".It's described pretty well.The equation (1) shows that the integration is done for the normalized data.
Anyway...this discussion is meaningless.The fact is that the RMS is the 70% of the peak and naturally higher in fast lifting.End of story.
Those press up studies are perfectly designed...your mind is flawed.
For example....compare the durations and the Total Muscle Activations.
Slow push ups:Duration=101.2 sec.....TMA(triceps)=3145.29
Fast push ups:Duration= 84.2sec......TMA(triceps)=2138.91
The duration of the slow push ups is only ~20% greater but the Total Muscle Activation is ~47% greater
.This is a direct PROOF that slow push ups have greater muscle activation per unit of time.
We have such a well designed study examining exactly what you're looking for and you're still around forums saying NONSENSE.
