Slow or fast

for any exercise, what would be the difference? strength, power, etc.

That is a very vague question, i'm sure someone will take a stab at it if you elaborate a little

I mean, for example, SLS, whats the difference (if any) by doing it at a fast pace or a slow pace? Same thing for, lets say, bulgarian dips? Will there be more strength involved in it by doing it very slowly, lower to a count of 5 or more, and push up to the same count?

What matters is the intent. For example if the exercise is so hard that even when you are trying to do it as fast as you can it is still slow, it is as optimal as if you are doing an easier exercise and the actual speed becomes faster. The famous WSB program combines speed lifting and heavy lifting with some pretty damn good results. Oh and so does the GB program ;=)

Like Razz said .

Intentionally slow training is useful for :

-rehab

-learning movements/solidifying technique

-bodybuilding purposes (it promotes more metabolic adaptations)

For all other purposes, training with a moderate tempo and for relative strength work (1-6 reps), thinking going as fast as possible is generally the most bang for your buck. For the reasons which Razz said, the intent of the exercise causes the adaptation and leads the recruitment of more motor units.

If it's a case of 7-25 reps, you probably won't be able to think explode anymore after a while. That's alright, just focus on making the lift as fast as you can.

The book Poliquin's Principles, by Charles Poliquin, has a very informative chapter on tempo, the adaptations associated with different tempo, the means of implementing variations of tempo, and examples of such implementation.
