It seems people just love to redefine things.
3 sets of 12 reps with 1 minute between them - not 'strength' training as I understand it, more akin to bodybuilding styles of training (strength training is high weight, low reps, not this)
an hour? for someone who is presumably completely untrained and chronically ill?
1 session cannot be strength training, 1 session is just picking things up for a bit.
If 1 session is as effective as many, and I have done many, then why am I not in a good mood when I read this?
ETA
Patients
performed the following exercises: knee
extension, knee flexion, bench press, fly,
adductors, low rowing, high pulley, elbow
extension, lateral raise, arm curl, standing
calf raise, and abdominal crunch
Not strength training
(given the 3 x12 stated presumably the 1 minute break is between sets, or maybe between switches, or maybe they are doing 3 reps or each exercise for 12 different exercises - which would make more sense for a chronically ill test group, if it wasn't for the simple fact that 3 reps of anything is not going to do anything physiologically useful for someone who isn't totally bed bound, unless the weight/effort is at the maximum attainable, and for that group it's too much
As written they are asking people to do 3 sets of 12 reps of 12 exercises, in 50 minutes, that's a hell of a lot for someone who won't have been in the trial if they did any exercise in the last 3 months and far more than can be done with correct form even for those who are trained IMO)
ETA2 - math
1 minute break between sets - 3 sets of 12 exercises (forget about any break or transition time between different exercises) is around 34 minutes resting during the 50 minute session (10 minutes were allocated to warm up out of the 60 minute session). No rest break between sets makes it not 3x12 but 1x36 rep set so there must be one.
So 3x12x12 movements - in 16 minutes = an average of 28 reps a minute - this isn't any form of resistance training at all - it's cardio.
My gut tells me there is more to it than that, but apparently maths is not within my capabilities today.
So this does not make sense as written.
