The purpose of this study was to test the anabolic window theory by investigating muscle strength, hypertrophy, and body composition changes in response to an equal dose of protein consumed either immediately pre- versus post-resistance training (RT) in trained men. [...] Key Method Subjects were 21 resistance-trained men (>1 year RT experience) recruited from a university population.Expand
The effects of nutrient timing on training adaptations in resistance-trained females.
TLDR
Peri-workout nutrition is potentially important for upper body strength and metabolism and PRE may be more effective for promoting fat utilization immediately post- workout. Expand
Effects of Protein Supplementation on Performance and Recovery in Resistance and Endurance Training
TLDR
It appears that peri-exercise protein intake, particularly in the post-training period, plays a potentially useful role in terms of optimizing physical performance and positively influencing the subsequent recovery processes for both resistance training and endurance exercise. Expand
Effects of Whey Protein Supplementation Pre- or Post-Resistance Training on Muscle Mass, Muscular Strength, and Functional Capacity in Pre-Conditioned Older Women: A Randomized Clinical Trial
TLDR
Whey protein supplementation was effective in promoting increases in SMM, muscular strength, and functional capacity in pre-conditioned older women, regardless of supplementation timing. Expand
Protein timing has no effect on lean mass, strength and functional capacity gains induced by resistance exercise in postmenopausal women: A randomized clinical trial.
TLDR
Protein timing has no effect on lean mass, strength and functional capacity gains induced by resistance exercise in postmenopausal women. Expand
Effects of whey protein supplementation prior to, and following, resistance exercise on body composition and training responses: A randomized double-blind placebo-controlled study
TLDR
The results suggest that the composition and timing of protein intake are more important than the total amount. Expand
Effects of post exercise protein supplementation on markers of bone turnover in adolescent swimmers
TLDR
The results shed light on the potential importance of protein consumed shortly after intense swimming in promoting positive bone turnover responses up to 24 h following exercise in adolescent athletes. Expand
Intake of whey isolate supplement and muscle mass gains in young healthy adults when combined with resistance training: a blinded randomized clinical trial (pilot study).
BACKGROUND Whey protein is consumed worldwide by athletes due to its alleged benefits on muscle mass and strength. Because of its rich branched chain amino acids content, namely leucine, whey appearsExpand
Muscle Hypertrophy Response Is Affected by Previous Resistance Training Volume in Trained Individuals.
TLDR
In conclusion, individualizing the weekly training volume of research protocols provides greater gains in muscle CSA than prescribing a group standard RT volume. Expand
Achieving an Optimal Fat Loss Phase in Resistance-Trained Athletes: A Narrative Review
TLDR
In this narrative review, the scientific literature is evaluated, and dietary–nutritional and supplementation recommendations for the weight loss phase of resistance-trained athletes are provided. Expand
The Role of Protein Intake and its Timing on Body Composition and Muscle Function in Healthy Adults: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.
TLDR
The results support the positive impact of protein supplementation on LBM of adults and older adults, independently of intake timing and effects on muscle strength and synthesis are less clear and need further investigation. Expand

Effects of supplement timing and resistance exercise on skeletal muscle hypertrophy.
TLDR
Examining the effects of supplement timing compared with supplementation in the hours not close to the workout on muscle-fiber hypertrophy, strength, and body composition during a 10-wk RE program concluded that supplement timing represents a simple but effective strategy that enhances the adaptations desired from RE-training. Expand
Effect of protein-supplement timing on strength, power, and body-composition changes in resistance-trained men.
TLDR
Results indicate that the time of protein-supplement ingestion in resistance-trained athletes during a 10-wk training program does not provide any added benefit to strength, power, or body-composition changes. Expand
Timing of postexercise protein intake is important for muscle hypertrophy with resistance training in elderly humans
TLDR
It is concluded that early intake of an oral protein supplement after resistance training is important for the development of hypertrophy in skeletal muscle of elderly men in response to resistance training. Expand
The effect of protein timing on muscle strength and hypertrophy: a meta-analysis
TLDR
Results refute the commonly held belief that the timing of protein intake in and around a training session is critical to muscular adaptations and indicate that consuming adequate protein in combination with resistance exercise is the key factor for maximizing muscle protein accretion. Expand
Protein supplementation before and after resistance training in older men
TLDR
RT was sufficient to overcome deficits in muscle size of the elbowflexors and ankle dorsi flexors and leg press strength in older compared to younger men, and Supplementation with protein before or after training has no effect on muscle mass and strength. Expand
Timing of amino acid-carbohydrate ingestion alters anabolic response of muscle to resistance exercise.
TLDR
The results indicate that the response of net muscleprotein synthesis to consumption of an EAC solution immediately before resistance exercise is greater than that when the solution is consumed after exercise, primarily because of an increase in muscle protein synthesis as a result of increased delivery of amino acids to the leg. Expand
Effects of resistance training and protein plus amino acid supplementation on muscle anabolism, mass, and strength
TLDR
Ten-wks of resistance training with 20 g protein and amino acids ingested 1 h before and after exercise is more effective than carbohydrate placebo in up-regulating markers of muscle protein synthesis and anabolism along with subsequent improvements in muscle performance. Expand
Concurrent resistance and aerobic exercise stimulates both myofibrillar and mitochondrial protein synthesis in sedentary middle-aged men.
TLDR
It is suggested that CE-induced acute stimulation of myofibrillar and mitochondrial FSR, protein signaling, and mRNA expression are equivalent to either isolate mode (RE or AE), and results occurred without an interference effect on muscle protein subfractional synthesis rates,protein signaling, or mRNA expression.

The Effects of Pre- and Post-Exercise Whey vs. Casein Protein Consumption on Body Composition and Performance Measures in Collegiate Female Athletes.
TLDR
The combination of a controlled undulating resistance training program with pre- and post-exercise protein supplementation is capable of inducing significant changes in performance and body composition and there does not appear to be a difference in the performance- enhancing effects between whey and casein proteins.

Influence of Resistance Training Frequency on Muscular Adaptations in Well-Trained Men
TLDR
The findings suggest a potentially superior hypertrophic benefit to higher weekly resistance training frequencies, as shown in results showed significantly greater increases in forearm flexor MT for TOTAL compared with SPLIT. Expand
