​

Purpose: The purpose of this investigation was to identify the load that maximizes power output in the jump squat (JS) in adolescent athletic men, and concurrently describe their strength level and its effect on the load that maximizes power output.

​

Conclusions: It was concluded that the load that maximizes power output in the JS is 0% of 1RM in adolescent athletic men, the same as found in college-aged athletic men. In addition, strength level relative to body mass did not affect the load that maximized power output. Practically, when devising a training program to increase power production, it is important to include JSs at body mass along with traditional strength training at heavier loads to increase power output across the entire loading spectrum.

IN PLAIN ENGLISH: FINALLY, THE TRUTH BE TOLD!!...you can jump higher and exude maximal power output unabated by resistance. Whether it is 1 pound, 50 pounds or 250 pounds you have riding on your body, IT WILL SLOW YOU DOWN, ALL OTHER FACTORS BEING EQUAL! It does not take a genius to figure this out. Practice your jumping/explosive skill execution without resistance to improve that ability. They put a man on the moon in July of 1969, and yet today there are many who cannot comprehend this simple law of physics/skill acquisition.
