In the second part with Dr. Jorn Trommelen (Assistant Professor, Department of Human Biology, Maastricht University, The Netherlands), we talk about Jorn's recent study on pre-sleep protein ingestion after acute endurance exercise to stimulate muscle protein synthesis. Jorn explains how these findings from acute studies relate to boosting long-term gains in strength, hypertrophy and endurance performance in response to regular pre-sleep protein ingestion. Based on his studies, Jorn shares his view on practical recommendations for pre-sleep protein in endurance- and resistance-training types of sports.
