Figures & data
Figure 1 Division of studies on “protein spread” and “protein change” theories and resistance training. 1 Reason for exclusion listed only once – some studies may have been excluded for meeting multiple exclusion criteria.
Table 1 Summary of 17 studies reviewed on protein and resistance training
Figure 2 Spreads in protein consumption between higher and lower protein groups in protein spread analysis. Spread Benefit = those studies in which the higher protein group experienced greater muscular benefits than controls during the intervention; Spread No > Benefit = those studies in which the higher protein group experienced no greater muscular benefits than controls during the intervention.
Table 2 Percent spread in protein intake between groups in studies included in protein spread theory analysis
Figure 3 Percent deviation from habitual protein intake among groups in protein change analysis. Change Benefit = those baseline reporting studies in which the higher protein group experienced greater muscular benefits than controls during the intervention; Spread No > Benefit = those baseline reporting studies in which the higher protein group experienced no greater muscular benefits than controls during the intervention.
Table 3 Protein change theory studies showing muscular benefits of increased protein versus control
Table 4 Protein change theory studies showing no > muscular benefits of increased protein versus control
