Abstract:We performed a systematic review to map the evidence and analyze the effect of whey protein supplementation in the elderly submitted to resistance training. Methods: A comprehensive search on Medline, LILACS, EMBASE and the Cochrane Library for relevant publications was conducted until August 2015. The terms used in the search were: "Resistance Training"; "Whey protein"; "elderly". Two authors independently assessed abstracts, texts in full and made critical appraisal. Results: A total of 632 studies were screened. Five studies were included composing a sample of 391 patients. The supplement whey protein was associated with higher total protein ingestion 9.40 (95% CI 4.03 to 14.78), and with an average change in plasma leucine concentration ranging from 406µmol/L to 490µmol/L compared with the control group. The supplementation was also associated with increased mixed muscle protein synthesis 1.26 (95% CI 0.46 to 2.07) compared to control group. Just one trial compared lean body mass in the group receiving whey protein supplementation and the control group (n=80) 0.07 (95% CI -0.37 to 0.51). Conclusion: We observed an increase in total protein intake, resulting in increased concentration of leucine and mixed muscle protein synthesis rate. No significant increase related to muscle mass or strength were observed.
