What is the difference between these two? In fact, what are they? I'm gonna guess stuff like Farmer's Walks is a strength endurance exercise while high rep snatches is a power endurance exercise. Can anybody help clarify between the two?

Thanks,
Kurt

Strength endurance would be like a long distance farmer walk, but since power is defined as being a product of work/time I'm not so sure there is such a thing as power endurance. Strength would actually factor into the power equation. I'll try my best to give an example, suppose you carry 70 lb dumbells for a mile in 15 minutes, carrying them that far and long is strength endurance. But say you try again the next week and it takes 14 minutes, still strength endurance but your power has increased, same work less time. I'm not sure that power and endurance go together since the ideal result for power in the example would be to shorten the amount of time to complete the task. Hope that helps, and if anyone else has insights I'd love to hear them.

Climbers use those terms.

Power endurance refers to that grey area between pure power (1RM in weightlifting terms) and endurance (running, rowing, 1000 broomstick snatches, etc). So, yes, high rep snatches would be an example... as long as it's at a sufficiently high weight, that doing one is "difficult".

Fran at any sub 5min time is a perfect example.

Strenght endurance is a bit more blurry... it can either mean static strenght "holds" ie... the farmers walk example. Or closer to just endurance... the ability to keep climbing all day...

my pennies worth -

strength endurance - the ability to repeatedly peform feats of strength

power endurance - to repeatedly perform feats of strength at speed

strength is the ability to overcome force
power is the use of strength at speed

I would also say that strength utilised over a period of time is more closely related to stamina and not endurance

hope that made sense!

You see the dilema, since power is a component of speed which in nature would contradict any definition of endurance I guess power endurance could occur if the goal wasn't to shorten the time it takes to complete a task but rather increasing the task done in the same time period. In exercise these terms are sometimes double edged, olympic lifts are examples of strength and power, I would simply agree with Paul and say repetitive snatches would be plain old stmina.
Stamina - capacity to maintain repetitive muscular movements
Strength - ability of a muscular unit, or combination of muscular units, to apply force
Power - ability of a muscular unit, or combination of muscular units, to apply maximum force in minimum time.
