At a club in Zagreb eight archers, four compound and four recurve, each shot fifteen arrows at 18 metres wearing a heart rate monitor, and the compound archers had the higher heart rate at all four moments measured: two seconds before the release 107.6 beats per minute against 101.1, one second before 109.1 against 100.8, at the release 111.5 against 103.2, one second after 112.9 against 104.7. The gap remains when arrows of the same score are compared (on the 10s, 118.5 against 107.0), so it is not explained simply by the compound archers shooting better, 9.17 points per arrow against 8.80. The limits, though, are large. The analysis treats the 120 arrows as independent observations when they come from eight people: the comparison is really between four archers and four others, and the p-values are inflated as a result. The group had three women and five men, and the study does not say how they were split between the two bows; there is no resting heart rate, which would show whether the difference comes from the shot or from the people; and the shooting was a training session, without the pressure of competition.claim:frequenza-cardiaca-compound-ricurvo:revision:2026-06-09:2Tue, 09 Jun 2026 08:00:00 GMT https://matteocampagna.com/en/registry/competition/heart-rate-compound-vs-recurveclaim:frequenza-cardiaca-compound-ricurvo:new_claim:2026-04-27:riportatoMon, 27 Apr 2026 08:00:00 GMT
