https://matteocampagna.com/en/registry/mind/mental-skills-training-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/mental-skills-training-scoreStudies of archers with a comparison group are few, and they split two and two. In favour: twelve archers of the Hong Kong squad gain 11.3 points over seventy-two arrows after twelve weeks of mindfulness while the matched controls drop by three, and thirty-six Turkish beginners gain more with eight weeks of imagery or slow breathing than a group doing training alone. Against: eighteen Greek archers with two official competitions as the measure show no difference after four weeks of imagery and relaxation, with adherence checked, and sixteen Ukrainian archers randomised to autogenic training are indistinguishable from controls after one week, with the score data unpublished. The rest weighs less: a meta-analysis of seventeen Korean studies gives a mean effect of 0.47 but pools anxiety, questionnaires and performance; a well-documented single case gains nine percentage points across nine competitions, and an older one improves with hypnosis on tests at 25 metres; the before-and-afters with no control show nothing on their own; and two Indian randomised trials in favour sit in journals with questionable editorial standards, with the shooting test barely described, if at all, while a third, from 2016, adds shoulder strengthening to the mental work and reports no means. What can be glimpsed, and nobody has yet tested, is that duration matters: the two null results come from the shortest programmes and the two favourable ones in reliable venues from eight and twelve weeks, even though one of the Indian trials finds a large effect after four.claim:allenamento-mentale-punteggio:revision:2026-09-26:6Sat, 26 Sep 2026 08:00:00 GMT https://matteocampagna.com/en/registry/mind/mental-skills-training-score#storiaThe meta-analysis of the seventeen Korean studies run between 1990 and 2017 arrives: a mean effect of g = 0.47, falling to 0.40 once publication bias is corrected and still positive. It is not enough to raise the status, for four reasons the meta-analysis states itself: the studies are all Korean and very small, from eight to forty archers, two hundred and seventy-three in all; two thirds of the variance between studies is genuine heterogeneity; the theses report effects almost twice those of the articles; and the outcome is a pooled measure of anxiety, reported skills and performance, not the competition score. The same year, twenty-three university archers in Taiwan improve their score over seventy-two arrows after eight mindfulness sessions, but with no control group and a small effect. Also in 2021, a Turkish study of curlers, bowlers and archers finds that four weeks of imagery, especially in virtual reality, raise the shooting score more than in a group that only watched videos of their sport; but the archers are seven out of thirty-four and are not reported separately, so it counts as other sports and does not move the status for archers. The status stays contested: the only study of archers with a control group that isolates the mental work, in a reliable venue, is still the Greek one, which found nothing.claim:allenamento-mentale-punteggio:history_entry:2026-08-20:2021Thu, 20 Aug 2026 08:00:00 GMT https://matteocampagna.com/en/registry/mind/mental-skills-training-score#storiaAn Indian randomised trial on thirty national-level archers reports that after six weeks the score at 50 metres has improved more than in the control group, but the mental training comes bundled with shoulder strengthening, and the results are one number per group with no means: it does not isolate the effect of the mental work, and the journal has questionable editorial standards. The registry keeps it as context, and the picture stays as it was in 2011: three uncontrolled cases in favour, the Greek study with a control group against.

The shooting test is not described and the tables do not match the stated design. The duration stands out, four weeks like the Greek study that found nothing, but with a venue and a report like these it is not enough to unsettle the idea that duration matters. Among studies in reliable venues the count stays at two in favour and two against, and the status remains contested.claim:allenamento-mentale-punteggio:status_change:2026-06-25:contestatoThu, 25 Jun 2026 08:00:00 GMT https://matteocampagna.com/en/registry/mind/mental-skills-training-score#storiaThe first attempt with a comparison group arrives, and finds nothing: four weeks of imagery and relaxation, eight sessions plus practice at home, in eighteen Greek archers, with two official competitions as the before and after measure. Both groups gain about fifteen points out of six hundred and the analysis of the post-test finds no difference. One study only, and it points the other way: contradicted, which is as much as a single paper can carry.claim:allenamento-mentale-punteggio:status_change:2026-04-29:contraddettoWed, 29 Apr 2026 08:00:00 GMT https://matteocampagna.com/en/registry/mind/mental-skills-training-scoreclaim:allenamento-mentale-punteggio:new_claim:2026-03-03:non_studiatoTue, 03 Mar 2026 08:00:00 GMT
