https://matteocampagna.com/en/registry/mind/heart-rate-score Changes to this claim in Matteo Campagna's evidence registry: its status, its year-by-year history, revisions of the page. en-gb https://matteocampagna.com/en/registry/mind/heart-rate-scoreThirty-five years of measurement and the picture has not closed: the observations say yes, the experiments say no. On one side, from four elite archers in 1990 to fifty arrows filmed in competition in 2025, archers shooting with a lower heart rate, or whose heart slows over the last cycles, score higher, and in 2025 two independent groups find it again with strong correlations. On the other, when an intervention has moved heart rate the score has not followed: raised by running it costs no points, lowered by a beta-blocker under double-blind conditions it adds none, and raised by nicotine it even comes with a higher score. In between sit studies that find nothing and one detail worth pausing on: where the relationship was examined score by score, arrows worth ten came with a higher heart rate than arrows worth nine, slightly in one study and by eight beats in the other. The most prudent reading of all this is that the slowing accompanies a good shot without causing it.claim:frequenza-cardiaca-punteggio:revision:2026-09-12:5Sat, 12 Sep 2026 08:00:00 GMT https://matteocampagna.com/en/registry/mind/heart-rate-score#storiaA second study of archers looks at heart rate arrow by arrow and finds the reverse of the claim. In eight experienced Croatian archers, in compound the tens start with the higher heart rate, 118.5 a minute at the release against 110.1 on the nines and 101.3 on the eights, and the difference is significant at every moment measured; in recurve the trend is the same, but it holds only two seconds before the shot. The arrows of the four archers in each group are pooled and the journal is regional, but it compares arrows with each other as the 1990 study did, and reaches the opposite result: with the kyudo archers of 1994, the contrary studies become two, and the status stays contested.claim:frequenza-cardiaca-punteggio:history_entry:2026-09-04:2015Fri, 04 Sep 2026 08:00:00 GMT https://matteocampagna.com/en/registry/mind/heart-rate-score#storiaTwo small studies pull in opposite directions in the same year. In ten Indonesian university archers the group with the lower heart rate while aiming, all men and with almost twice the years of practice, scores 7.97 points per arrow against 6.47: sex and experience travel with heart rate, and with ten people they cannot be separated. In twenty compound archers from a state squad, average heart rate over thirty-six arrows at fifty metres is not associated with score, and the only measure that counts is self-confidence. A third figure, in a journal with questionable editorial standards, even runs the other way: in thirty-two Malaysian juniors training at home during the COVID-19 isolation the better archers have the higher heart rate before and after the session, with no test. The status does not change.claim:frequenza-cardiaca-punteggio:history_entry:2026-07-23:2023Thu, 23 Jul 2026 08:00:00 GMT https://matteocampagna.com/en/registry/mind/heart-rate-score#storiaA small Korean study moves heart rate without meaning to: in six middle school archers, after a sleepless night with caffeine the heart rate while shooting at thirty metres is lower than after a normal night or a sleepless night with a placebo, and the score stays the same, between 335 and 339 out of 360. Heart rate changes here together with sleep and caffeine, so it is not a clean test, but it points the same way as the 2016 null: a lower heart rate does not turn into points. The same year, in thirty-two young Malaysian archers, resting heart rate does not separate those who score more from those who score less: it is the heart rate before shooting starts, not at the shot, and it stays as context. The status stays contested.claim:frequenza-cardiaca-punteggio:history_entry:2026-07-23:2017Thu, 23 Jul 2026 08:00:00 GMT https://matteocampagna.com/en/registry/mind/heart-rate-score#storiaThe split widens with better data on both sides. In favour: forty-five traditional Turkish archers, where those with the lower average heart rate while shooting score higher, with a strong correlation in the women and a moderate one in the men; thirty-two Indian archers, where heart rate while aiming, at release and in the follow-through is negatively correlated with score; and fifty video clips from international competitions, where heart rate estimated from the face remains the heaviest variable alongside arm movement. Against: in the Indian study a second session with a lower heart rate gives exactly the same score. These are cross-sectional associations on one side and a within-archer comparison on the other, and the contrary result in elite archers has not been withdrawn: contested.claim:frequenza-cardiaca-punteggio:status_change:2026-06-11:contestatoThu, 11 Jun 2026 08:00:00 GMT https://matteocampagna.com/en/registry/mind/heart-rate-scoreclaim:frequenza-cardiaca-punteggio:new_claim:2026-04-30:riportatoThu, 30 Apr 2026 08:00:00 GMT
