Here are a couple of good articles on the role of maximal strength as it relates to strength endurance. One is by
Pavel Tsatsouline., the other by
Dave Whitley.
I think they explain quite well the importance of maximal, slow strength, even in an endurance event.Way too much emphasis is placed on endurance, cardio,etc.
Maximal strength is the foundation of almost all movements. It also protects against injuries. As the articles point out, there's no way if you're not physically strong to carry an injured car crash victim . Or climb up a mountain, especially with a 50 lb backpack.
Unfortunately too many people believe in only long cardio or super high reps. But as we've seen, if you don't have "strong" legs you're not going to make it up the mountain. Nor, if you don't have a strong grip, along with numerous other muscles like the core and legs, there's no way you're going to be able to carry a human being to safety.
Tell me if you think that only doing push ups, or even 75 reps of military presses with 10 lb dumb bells, will prepare you to press that 300 + lb log?
So remember, build a foundation of strength, and then you can modify as needed.
