Is Average Force the Same in Fast vs. Slow Weightlifting Reps?

Click For Summary
The discussion centers on whether average force exerted during fast versus slow weightlifting repetitions is the same and its implications for muscle tension. Participants argue that while average forces may appear similar, peak forces and energy expenditure differ significantly between fast and slow reps, leading to greater overall muscle tension during faster lifts. The "clay experiment" is used to illustrate that faster repetitions produce higher peak forces, which should result in more significant deformation of the clay compared to slower reps. Additionally, energy requirements for faster repetitions are higher, contributing to quicker fatigue. Ultimately, the consensus leans towards the idea that average forces are not equivalent, as peak forces and energy dynamics play crucial roles in muscle engagement.

I do not think the meaning of work, that is if you move a weight up and then down = zero, is helping this debate at all. As we all know here that force and energy have been used to lift the weight and to lower it under control, thus physical work has been done.
I have told you this many times already. Energy has been expended, but no work has been done. What is not helpful for the debate is for you to use the incorrect terminology when the correct terminology has been provided. These are technical words with specific mathematical meanings. If you want to learn science, which you have claimed several times is your goal, then you need to learn the meanings of the terms and use them correctly.

thats what I sort of said
so is it not like I just said above
However if we take some numbers,
I say
It would be the same

Stop all of this and start learning.

1. What you say contradicts itself.
2. As point 1.
3. Your numbers are meaningless.
4. You keep trying to explain things using incorrect knowledge.
5. A conclusion based on the above incorrect knowledge.

You need to try and understand this. How many times have you posted those numbers and how many times has everyone ignored - every time.

You are ignoring what you are being told and trying to apply your own flawed explanations. Just stop it.
