The Effects of Leucine-Enriched Branched-Chain Amino Acid Supplementation on Recovery After High-Intensity Resistance Exercise

Adam D. Osmond, Dean J. Directo, Marcus L. Elam, Gabriela Juache, Vince C. Kreipke, Desiree E. Saralegui, Robert Wildman, Michael Wong, and Edward Jo

supplementation attenuated the decrease in maximal voluntary contraction (MVC) 3 days following unaccustomed squat exercise, indicating greater recovery of MVC compared with a dextrin control. This may be partly attributed to the proanabolic effects of exogenous BCAA on skeletal muscle protein metabolism. 9 , 10

Effects of Timing and Types of Protein Supplementation on Improving Muscle Mass, Strength, and Physical Performance in Adults Undergoing Resistance Training: A Network Meta-Analysis

Huan-Huan Zhou, Yuxiao Liao, Xiaolei Zhou, Zhao Peng, Shiyin Xu, Shaojun Shi, Liegang Liu, Liping Hao, and Wei Yang

As recommended by the International Society of Sports Nutrition, additional protein supplementation is needed to achieve a positive net protein balance during resistance training (RT; Jäger et al., 2017 ). The roles of protein supplementation in enhancing muscle mass, strength, and physical

Routine Yoga Practice Impacts Whole Body Protein Utilization in Healthy Women

; Paddon-Jones & Rasmussen, 2009 ). Physical activity, strength training in particular, improves whole body protein balance (WBPB) in older individuals ( Timmerman et al., 2012 ; Walker et al., 2011 ). Of significance to this investigation is the potential of yoga as an alternative exercise option for the

Carbohydrate and Protein Co-Ingestion Postexercise Does Not Improve Next-Day Performance in Trained Cyclists

Hilkka Kontro, Marta Kozior, Gráinne Whelehan, Miryam Amigo-Benavent, Catherine Norton, Brian P. Carson, and Phil Jakeman

The relationship between postexercise carbohydrate (CHO) intake and subsequent endurance performance is well established, but equivocal evidence exists of the role of protein in the restoration of whole-body glycogen stores ( Alghannam et al., 2018 ). Several studies have suggested that providing

Making Sense of Muscle Protein Synthesis: A Focus on Muscle Growth During Resistance Training

Oliver C. Witard, Laurent Bannock, and Kevin D. Tipton

Muscle protein synthesis (MPS) is the metabolic process that describes the incorporation of amino acids into bound skeletal muscle proteins. Muscle proteins can be crudely classified into the contractile myofibrillar proteins (i.e., myosin, actin, tropomyosin, troponin) and the energy producing

Daily Myofibrillar Protein Synthesis Rates in Response to Low- and High-Frequency Resistance Exercise Training in Healthy, Young Men

Brandon J. Shad, Janice L. Thompson, James Mckendry, Andrew M. Holwerda, Yasir S. Elhassan, Leigh Breen, Luc J.C. van Loon, and Gareth A. Wallis

). However, most studies to date have examined the impact of resistance exercise training frequencies in the range of one to three times per week. It is possible that higher resistance exercise training frequencies (e.g., five times per week) are required to enhance muscle protein synthesis rates and

The Postprandial Plasma Amino Acid Response Does Not Differ Following the Ingestion of a Solid Versus a Liquid Milk Protein Product in Healthy Adult Females

Glenn A.A. van Lieshout, Jorn Trommelen, Jean Nyakayiru, Janneau van Kranenburg, Joan M. Senden, Lex B. Verdijk, and Luc J.C. van Loon

It has been well-established that protein ingestion increases muscle protein synthesis rates ( Biolo et al., 1997 ; Trommelen et al., 2019 ). The postprandial rise in muscle protein synthesis plays a key role in muscle maintenance and is instrumental in supporting the skeletal muscle adaptive

Protein Supplementation for Strength and Functionality in Older Adults: Is There Still Any Doubt? A Brief Update Review

Júlio Benvenutti Bueno de Camargo and Alexandre Ferraz de Oliveira

, with special attention to protein intake. It has been previously suggested that impairments in protein digestion and amino acid absorption, insulin-mediated muscle tissue perfusion, amino acid uptake in muscle, or a reduced phosphorylation of key signaling proteins may contribute to the phenomenon

The Anabolic Response to Protein Ingestion During Recovery From Exercise Has No Upper Limit in Magnitude and Duration In Vivo in Humans: A Commentary

Oliver C. Witard and Samuel Mettler

An elegant recent study published by Trommelen et al. ( 2023 ) in Cell Reports Medicine provides unique insights into the postprandial protein handling of a “meal-like” (25 g) or “feast-like” (100 g) dose of protein ingested following an intense (60 min, 4× 10 sets/reps @65%–80% one repetition

Evening Whey Protein Intake, Rich in Tryptophan, and Sleep in Elite Male Australian Rules Football Players on Training and Nontraining Days

protein ( Falkenberg et al., 2021 ; Ong et al., 2017 ) intake can influence sleep. However, little is known about the impact of nutritional intake on sleep in elite athletes. Protein is a large component of an athlete’s diet, essential for adequate muscle growth and repair ( Thomas et al., 2016 ). Elite
