SponsorshipThe study was supported by the Spanish Ministry of Education (FPU 13/ 04365 and 15/04059), by the Redes temáticas de investigación cooperativa RETIC (Red SAMID RD16/0022), and by the University of Granada Plan Propio de Investigación 2016 -Excellence actions: Unit of Excellence on Exercise and Health (UCEES) - and Plan Propio de Investigación 2018 - Programa Contratos-Puente, and the Junta de Andalucía, Consejería de Conocimiento, Investigación y Universidades (ERDF: ref. SOMM17/6107/UGR), and by the Interprofessional Dairy Organization (INLAC) of Spain.
Dairy products are thought to improve recovery after both resistance and endurance exercises due to their nutritional proprieties. We systematically reviewed the effects of dairy product intake on exercise performance and recovery of muscle function in humans. A literature search was conducted in the MEDLINE (via PubMed) and Web of Science databases from their inception to 15th April 2018. The initial search retrieved 7708 articles, and a total of 11 studies were finally included after applying inclusion and exclusion criteria. All the selected studies were conducted with cow’s milk. Whereas some studies found significant positive effect of cow’s milk on exercise performance and recovery of muscle function, others did not find any effect. These controversies could be due to the heterogeneity of cow’s milk ingestion (e.g., amount of cow’s milk, timing of consuming the cow’s milk), to the type of intervention, and to the large heterogeneity of outcomes measured. Limited studies exist examining the effects of cow’s milk consumption and its influence on exercise performance and recovery of muscle function, therefore further studies are needed to draw more definitive conclusions.
