Summary of previous meta-analyses on set-volume and strength development.

References	Study objective	Exercise type	Summary findings
Rhea et al., 2003	Identify a dose-response relationship for intensity, frequency, and volume of training	MJ and SJ comb	Untrained and trained subjects should perform four-sets per muscle group.
Peterson et al., 2004		MJ and SJ comb	Athletes should perform eight-sets per muscle group for athletes.
Peterson et al., 2005	Review of recent evidence on strength development research	MJ and SJ comb	Untrained subjects should perform four-sets per muscle group. Trained subjects should perform eight-sets per muscle group.
Wolfe et al., 2004	Examination of single-set vs. multiple-set on muscle strength	MJ and SJ comb	MS (two-five sets) elicit superior strength gains for trained subjects. Untrained subjects should perform S initially.
Krieger, 2009	Comparison of the effects S-vs.-MS per exercise have on strength	MJ and SJ comb	Maximal strength gains are elicited with two-three-sets per exercise than S, in both untrained and untrained subjects.
Fröhlich et al., 2010	Comparison of the effects of S-vs.-MS for increasing maximal strength levels	MJ and SJ comb	S regimes are equivalent to MS training for increasing strength in the initial period. MS training is superior overextended periods.

N, number; MJ, multi-joint; SJ, single-joint; comb, combined; MS, multiple-sets; S, single-joint.
