In 2020, in twelve young Malaysian recurve archers split into two groups by score, the better group had 34.9 per cent muscle mass against 29.9, but the difference sits just above the significance threshold (p = 0.055), and the mass is read from an electronic scale without the paper saying how it is estimated. In 2024, in fifteen Japanese university kyudo archers, those with national placings had a higher skeletal muscle index, 6.7 against 6.0 kg/m², without being taller, heavier or more experienced; but they also shot twenty more arrows a day, and the stronger group was all male against half of the other, so the difference is mixed up with sex and with how much they shoot. It is a single supporting study, on kyudo, and nobody says whether the muscle comes before the level or whether hours of shooting bring both. Grip strength, which in the same studies is higher in the better archers, has its own entry.claim:presa-massa-livello:revision:2026-06-04:2Thu, 04 Jun 2026 08:00:00 GMT https://matteocampagna.com/en/registry/physical-training/muscle-mass-archer-levelclaim:presa-massa-livello:new_claim:2026-05-04:riportatoMon, 04 May 2026 08:00:00 GMT
