The most spectacular result, a correlation of 0.906 in thirty-one youngsters, explains itself: in that same sample balance, strength and endurance correlate with each other between 0.83 and 0.91, which makes them nearly the same measure, and as soon as they enter the model together balance stops counting (beta 0.129, p = 0.312). The other supporting result is weak, 0.262 in sixty children aged 12 to 13. On the other side seven samples, from twelve young Malaysian recurve archers to forty-five adult traditional archers and thirty professional compound archers, show no link at all, with coefficients that, where they are reported, sit between -0.26 and 0.37 without ever reaching significance. In those same compound archers, though, the ones who improved their balance most over twelve weeks also gained the most points: the link that does not show between one archer and another appears in the changes within the same archer, in a group with no control. One clue about where to look remains: in the Turkish study, static and dynamic balance go together, but only the dynamic kind is linked to the score. The suspicion, which a review from the same period puts in writing, is that standing still on one leg measures something shooting does not ask for.claim:equilibrio-statico-punteggio:revision:2026-08-01:3Sat, 01 Aug 2026 08:00:00 GMT https://matteocampagna.com/en/registry/physical-training/static-balance-and-score#storiaForty-five adult traditional archers, measured on the flamingo test, show no link between single-leg balance and score in either sex, and in that same sample the losses of balance are the same for men and women. In the same year twenty Indonesian under-13s confirm it: in the regression, single-leg balance does not predict the score (p = 0.785), and nor does any of the other fitness tests. The contrary side strengthens and the status stays contested.claim:equilibrio-statico-punteggio:history_entry:2026-07-25:2025Sat, 25 Jul 2026 08:00:00 GMT https://matteocampagna.com/en/registry/physical-training/static-balance-and-score#storiaHere the picture breaks in two. In thirty-one archers aged 13 to 18 the correlation between balance and score is very high (r = 0.906), but it vanishes as soon as strength and endurance enter the model (beta 0.129, p = 0.312), and the study itself explains why: balance, strength and endurance rise together with correlations between 0.83 and 0.91, close enough to be nearly interchangeable. A review from the same year warns that tests taken standing still may not separate athletes of different levels, because the differences show up in sport-specific tasks. Studies of archers pointing in opposite directions: contested. In the same year thirteen Indonesian archers give a correlation of 0.884 between balance and score, but the test is not described and the journal is questionable, so it stays as context.claim:equilibrio-statico-punteggio:history_entry:2026-07-25:2022Sat, 25 Jul 2026 08:00:00 GMT https://matteocampagna.com/en/registry/physical-training/static-balance-and-score#storiaA second study of archers points the same way as the first. In twelve young Malaysian recurve archers, split into the six strongest and the six weakest over thirty-six arrows at 70 metres, single-leg balance neither separates the two groups nor links to the score, with coefficients of 0.19 and 0.37, well short of significance. Two contrary studies and none in favour, but both are one-off associations, one on twelve archers and the other on a single end of six arrows: they are not enough to say that several well-conducted studies show no effect, so the claim stays contradicted rather than refuted.claim:equilibrio-statico-punteggio:history_entry:2026-07-25:2020Sat, 25 Jul 2026 08:00:00 GMT https://matteocampagna.com/en/registry/physical-training/static-balance-and-score#storiaThe same group publishes the figures, in all likelihood on the same fifty young Malaysian archers: in a model with the other fitness tests, one-leg balance is not linked to the score (beta -0.031, p = 0.843), and neither is the standing long jump. It is the same contrary evidence as in 2018, now measured: the claim stays contradicted.claim:equilibrio-statico-punteggio:history_entry:2026-07-25:2019Sat, 25 Jul 2026 08:00:00 GMT https://matteocampagna.com/en/registry/physical-training/static-balance-and-score#storiaThe question is first asked by a Malaysian group that splits young archers into high and low potential on the basis of score, fitness tests and coping skills: the better group is ahead on everything except static balance, which does not separate the two groups. It shows only in a graph, with no figures and no statistical tests, and the number of archers is not stated. A single study of archers, and pointing against: the claim stands contradicted.claim:equilibrio-statico-punteggio:history_entry:2026-07-25:2018Sat, 25 Jul 2026 08:00:00 GMT https://matteocampagna.com/en/registry/physical-training/static-balance-and-scoreclaim:equilibrio-statico-punteggio:new_claim:2026-05-04:contestatoMon, 04 May 2026 08:00:00 GMT
