are there studies comparing high volume to high intensity resistance training?

[Wesley_Clark]

is there a difference with regards to muscle size, strength, stamina, speed, speed of growth, etc when comparing a high volume training regimen (many sets of 8-15 reps, multiple exercises per bodypart) vs a high intensity regimen (one exercise per body part with one set consisting of regular reps followed by drop sets and assisted reps totaling 15-30 reps total)?

due to time constraints and my busy tv viewing schedule I’d rather do the high intensity workout. but are the outcomes the same?

im more concerned with strength training than endurance training for the purposes of this thread.

The go-to American College of Sports Medicine Guideline.

A variety of styles of training have been shown to
increase hypertrophy in men and women (3,49,157,249). In
untrained individuals, similar increases in lean body mass
have been shown between single- and multiple-set training
(175,228), although there is evidence supporting greater
hypertrophy enhancement with multiple-set training …

This finding has been supported, in part, by greater
hypertrophy associated with high-volume, multiple-set programs compared with low-volume, single-set programs in
resistance-trained individuals (149,155,169). Traditional RT
(high load, low repetition, and long rest periods) has
produced significant hypertrophy (96,258); however, it has
been suggested that the total work involved with traditional
RT alone may not maximize hypertrophy. Goto et al. (91)
showed that the addition of one set per exercise (to a
conventional RT workout) consisting of light loading for 25–
35 repetitions led to increased muscle CSA whereas
conventional strength training alone (e.g., multiple sets of
3–5 RM) did not increase muscle CSA. The addition of the
high-volume sets led to greater acute elevations in GH (91) …

FWIW.

Not exactly the comparison you are asking for though, with dropped sets and assisted reps. It also must be noted that one set of a wide enough variety of compound lifts will functionally give each muscle group several sets of stimulation albeit from slightly different angles and combinations.
