Of the fourteen balance and movement measures compared, seven do not change: among them the angular velocity of the lower back before and after the release, the forward-backward sway in the half-second before, and the total and sideways displacement of the centre of pressure in the tenth of a second after. The other seven do. Before the release the centre of pressure travels 51.9 millimetres in recurve and 61.6 in compound, sideways sway is 1.1 against 1.5 millimetres, and the drawing wrist moves more than twice as much in recurve; after the release the compound archers sway less forwards and backwards, 3.2 millimetres against 5.4, and have lower angular velocities at the ankle and both wrists. What predicts the score also changes from one bow to the other. As early as 1999 a Swedish study of twenty young archers had noticed, in passing, that the finger extensor of the drawing arm was far less tense before the release with the compound than with the freestyle bow. The measures that come out equal rest on small groups, where moderate differences can slip through, and some of the differences are large; but the two bows were shot at different distances, 70 and 50 metres, and with a single study pointing both ways the picture remains contested.claim:ricurvo-compound-stesso-corpo:revision:2026-08-14:2Fri, 14 Aug 2026 08:00:00 GMT https://matteocampagna.com/en/registry/technique/recurve-compound-same-body-movementclaim:ricurvo-compound-stesso-corpo:new_claim:2026-07-30:contestatoThu, 30 Jul 2026 08:00:00 GMT
