Deadlift versus Squat

I found this some informations about dead and squat but not something about Dead VS Squat… if you have any informations… I found Squat versus leg Press, Squat vs Hack Squat, partial Squat versus Squat, Sumo vs Conventional etc.

"It is thought that during a squat and deadlift, both the quadriceps muscles as well as the hamstrings muscles are activated (Escamilla et al., 1998). While the knee extends, the quadriceps muscles shorten and the hamstring muscles lengthen, but while the hip extends, the quadriceps muscles lengthen and the hamstrings shorten. The result is a simultaneous concentric and eccentric contraction at the opposite ends of each muscle (Baechle, 1994; Escamilla, 2000). Furthermore, electromyography (EMG), used to measure of the amount of muscle activity during a squat exercise in previous studies (Escamilla, 2000; Escamilla et al., 2001), showed that the squat elicited significant quadriceps EMG activity."

and THAT :

"The results demonstrated that shallow ¾ squatting (68º knee flexion), both wide and shallow stances, produced the greatest amount of quadriceps stimulation. Shallow squatting elicited 20% more muscular activation throughout the three quadricep muscles measured compared to full 90º squats.

This was evident from the EMG results, with the Biceps Femoris muscle being stimulated 50% more during full squats compared to shallow squats."

This is very interesting research, showing that hams are more targeted when doing full squats. I always felt more stimulation because I used more weight during shallow squats. When I first started squatting, I never went below parallel, and got great leg development.

Very interesting… I wonder if this applies to other compound movements such as Bench Press?

Dan,

How about heavy leg extensions for a more direct hit to the quads, thereby taking the glutes out of the equation?

Leg extension and leg press are inferior for overall thighs AND quads compared to Squat. At least according to the emg studies I found.
