Tim and Derrick are both doing squats at the gym with proper form, but Derrick is doing deeper squats at about 150 degrees of flexion while Tim is only going to 90 degrees. Which of the following is true?

Derrick is activating the quadriceps, hamstrings, and glutes more than Tim due to the greater degree of flexion.

Tim is activating the quadriceps, hamstrings, and glutes more than Derrick because past the point of 90 degree flexion the activation begins to drop for all the muscles.

Derrick is activating the quadriceps less, the glutes more, and the hamstrings the same as Tim.
