- A moderate serving of high-quality protein maximally stimulates skeletal muscle protein synthesis in young and elderly subjects
PubMed ID: 19699838
Robust acute increase in muscle protein synthesis after lean beef supports post‑exercise recovery and training adaptation—relevant to workout support.
- The Effects of Beef, Chicken, or Whey Protein After Workout on Body Composition and Muscle Performance
PubMed ID: 28399016
Postworkout beef protein isolate taken during resistance training produced favorable increases in lean mass and decreases in fat—supports use around training.
- Effects of progressive resistance training combined with a protein-enriched lean red meat diet on health-related quality of life in elderly women: secondary analysis of a 4-month cluster randomised controlled trial
PubMed ID: 28721837
Lean red meat with resistance training improved functional strength in older women—supports exercise outcomes.
- Protein-enriched diet, with the use of lean red meat, combined with progressive resistance training enhances lean tissue mass and muscle strength and reduces circulating IL-6 concentrations in elderly women: a cluster randomized controlled trial
PubMed ID: 24477043
Lean red meat plus RT increased muscle and strength in older women — supports exercise response.
Illness recovery (2)
- The Effects of Beef, Chicken, or Whey Protein After Workout on Body Composition and Muscle Performance
PubMed ID: 28399016
Postworkout beef protein isolate given after resistance training was associated with increased lean mass—suggests benefit for training recovery/adaptation.
- A moderate serving of high-quality protein maximally stimulates skeletal muscle protein synthesis in young and elderly subjects
PubMed ID: 19699838
Lean beef ingestion produced large acute increases in muscle protein synthesis—mechanistically consistent with faster muscle repair/recovery after exercise or damage.
