Does Protein Muscle Synthesis Meta-Analysis work?

Updated August 2026

Quick Answer

Protein Muscle Synthesis Meta-Analysis has evidence relevant to strength of evidence and what the studies can or cannot prove, but conclusions should stay close to the cited sources. One representative finding is: Meta-regression explored potential moderators, and risk of bias was assessed using the ROBINS-I tool.

Key Takeaways

  • 01Meta-regression explored potential moderators, and risk of bias was assessed using the ROBINS-I tool. [Kristiansen JB (2026)]
  • 02Post-prandial MPS was also reduced in older adults (SMD = -0.348; 95% CI: -0.627 to -0.070; p = 0.014; I² = 83.4%), with consistent directionality across sensitivity analyses. [Kristiansen JB (2026)]
  • 03Evidence for combined post-exercise MPS remains mixed, with evidence leaning toward a similar response in young and older adults. [Kristiansen JB (2026)]
  • 04Introduction Age-related declines in skeletal muscle mass and function are partly attributed to anabolic resistance, a diminished stimulation of muscle protein synthesis (MPS) following nutrient intake or exercise. [Kristiansen JB (2026)]
The current Migaku evidence database contains 2 reusable source documents for Protein Muscle Synthesis Meta-Analysis. This answer focuses on strength of evidence and what the studies can or cannot prove. - Meta-regression explored potential moderators, and risk of bias was assessed using the ROBINS-I tool. [Kristiansen JB (2026); evidence level 1] - Post-prandial MPS was also reduced in older adults (SMD = -0.348; 95% CI: -0.627 to -0.070; p = 0.014; I² = 83.4%), with consistent directionality across sensitivity analyses.

[Kristiansen JB (2026); evidence level 1] - Introduction Age-related declines in skeletal muscle mass and function are partly attributed to anabolic resistance, a diminished stimulation of muscle protein synthesis (MPS) following nutrient intake or exercise. [Kristiansen JB (2026); evidence level 1] - Contemporary diagnostic frameworks established by the European Working Group on Sarcopenia in Older People (EWGSOP) prioritize muscle strength assessment as the cardinal criterion, supplemented by confirmatory evidence of diminished muscle quality or quantity and compromised physical performance []. [Dharmansyah Dhika (2026); evidence level 3] Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording. This page is educational. People with medical conditions, pregnancy, medication use, or unusual symptoms should ask a qualified clinician before changing supplements, medication, or treatment routines.
