N-3 PUFA supplementation resulted in a significant increase in type II fibre cross-sectional area (CSA) from 3097 ± 339 μm2 to 4329 ± 264 μm2 (P < 0.05) compared to placebo.
N-3 PUFA may be beneficial for increasing muscle fibre size in older women.
StrongSupportsmedium confidence
Only the n-3 PUFA group increased... type II fibre CSA (3097 ± 339 μm2 to 4329 ± 264 μm2 n-3 PUFA (P < 0.05) vs. 2520 ± 316 μm2 to 3467 ± 303 μm2 in PL).
Why this rating
Based on the randomized double-blind placebo-controlled trial design.

- N-3 PUFA supplementation increased thigh fat free mass (TFFM) from 3774 ± 158 g to 3961 ± 151 g (P < 0.05) compared to placebo which increased from 3406 ± 201 g to 3561 ± 170 g.Strong
- N-3 PUFA had no added benefit on muscle protein synthesis (MPS) but showed a trend towards increased absolute synthesis rates (ASR) during weeks 4–6 of resistance exercise training.Strong

- Athletes aiming to reduce fat mass and preserve FFM should consume protein intakes in the range of ∼1.8-2.7 g kg(-1) d(-1).Strong
- A minimum daily protein intake of ≥1.6 g/kg is necessary to observe significant improvements in muscle mass from whey protein supplementation.Strong
- Most athletes ideally need 1.2 to 2.0 grams/kg of body weight/day of protein, preferably split across 3-4 meals.Strong
