Athletes?

Introduction

Collegiate athletes face great physical strains that require perfect recovery techniques
to ensure peak performance and injury reduction. Protein timing has become one of several
nutritional interventions that may play a critical role in accelerating muscle recovery and
hypertrophy after training, among other nutrition interventions. The protein timing strategy
involves the selective intake of this nutrient, mostly around exercise, which aims to achieve
maximum effect on muscle protein synthesis (MPS). The researchers have suggested that the
consumption of protein prior to or after exercise is better at enhancing muscle adaptation than
delayed intake. This paper discusses the research question: How does protein timing affect
muscle recovery and growth in collegiate athletes?
Methods
Using three databases, namely PubMed, ScienceDirect, and Google Scholar, a
systematic search was conducted in order to locate peer-reviewed primary research articles
published between 2020-2025. Search terms were “protein timing”, “muscle recovery”,
“muscle growth”, “collegiate athletes”, and “post exercise nutrition”. Filters were applied to
include only studies of full-texts involving human participants with emphasis on resistance-
trained participants aged 18-25. Studies that involved the use of protein around exercise and
measured outcomes in terms of muscle damage, soreness, hypertrophy, or protein synthesis
were prioritized. Five quality primary sources of texts were chosen with regard to relevance,
methodological strength, and population fit.
Results
Recent studies have looked at the effects of protein timing on muscle recovery and
growth among collegiate and recreational athletes. 2024 network meta-analysis considered
116 randomized controlled trials with 4711 participants2. The results of the study showed that
protein intake after exercise has significantly increased fat-free mass (MD). Compared with
the placebo, altered L-citrulline consumption increased lean muscle mass (MD: 0.54 kg) and
skeletal muscle mass (MD: 0.34 kg)2. Further, nighttime protein consumption significantly
improved handgrip strength (MD: 2.85 kg) and leg press strength (MD: 12.12 kg), suggesting
that post-exercise and nighttime protein strategies are both effective in promoting the increase
in muscle mass and strength.
