Abstract
Abstract
Context
Military personnel are subjected to physiologically stressful environments during combat and its associated training. Evidence suggests that fish oil–derived n-3 polyunsaturated fatty acids (FO n-3 PUFAs) may affect military personnel’s performance by promoting or preserving lean body mass, strength, and power, while enhancing recovery from training-associated muscle damage.
Objective
Following PRISMA guidelines, this systematic review assessed the evidence for FO n-3 PUFA supplementation across various military-relevant outcomes related to physical performance in healthy adult populations.
Data Sources
The PubMed, Embase, and the CINAHL databases were searched along with references lists of selected articles and reviews.
Data Extraction
Eighteen trials were assessed for bias, and descriptive data were extracted.
Data Analysis
Of the 18 studies included, 12 trials favored FO n-3 PUFA supplementation in ≥ 1 of the performance outcomes.
Conclusion
Overall, FO n-3 PUFA supplementation likely preserves strength and very likely enhances recovery from physiological stress in young, healthy adults. However, FO n-3 PUFAs’ role in promoting or preserving lean body mass or promoting strength is unclear and warrants additional investigation.

Abstract
There has been increasing interest and research into sarcopenia in community-dwelling older adults since the European Working Group on Sarcopenia in Older People (EWGSOP) agreed a consensus definition in 2010. Sarcopenia has been defined as loss of muscle mass with loss of muscle function (strength or physical performance), with measurements two Standard Deviations (SDs) below the mean of a young reference population. This definition does not necessitate longitudinal measurements, or the absence of acute illness and diagnosis can be made from single measurements. We hypothesise that hospitalisation, due to a combination of acute inflammatory burden and muscle disuse, leads to an acute decline in muscle mass and function and may lead to some individuals meeting criteria for sarcopenia, acutely, based on the EWGSOP definition. This may be partially recoverable or may lead to increased risk of developing sarcopenia long-term. We have denoted the term “acute sarcopenia” to refer to acute loss of muscle mass and function associated with hospitalisation. This review discusses some of the current available research in this context and also identifies some of the knowledge gaps and potential areas for future research.
