Archers with longer arms are more accurate

The summary today

The studies on archers are split, and split in a way that makes sense. In youth and club groups the link shows up: in twelve young Malaysian archers arm span is the measure most closely tied to the score (rho 0.822), and in twenty-three university club archers longer arms go with a few more points at 18 metres, 6.4 per cent of the variance. Among national and international archers, by contrast, the link disappears: in thirty-three Indian archers arm span exceeds height in every one of them and none of the eleven body measures is related to the score (r = -0.102 for the span index). In 2025 two very different samples, adult traditional archers and complete beginners, find nothing either. Three things limit the reading. Long arms travel with height and overall build, and in a mixed group with age and experience too, and no study has pulled them apart. Draw length, which is what matters on the bow, is not arm length. And these are all associations measured once, on small groups. Contested, with the hypothesis that among archers who have already been selected the measure stops telling them apart.

Also phrased as: "arm span and archery"; "long arms advantage in archery"; "long draw length and accuracy"; "body measurements and archery score"; "the archer's build"

Evidence

  Context Archers Published later

  62 male national-level recurve archers: draw length, not arm length, has a direct effect on the score of 0.15, 2.25 per cent of the variance, and a larger indirect one by way of technique (0.45 × 0.50 = 0.23). Draw length depends on the arms but also on posture and technique, so it stays as context.

  24 archers from the Perpani provincial squad in Aceh (Indonesia): arm length correlates with the accuracy test at 0.871. The paper's figures do not agree with each other, though: arm length and arm endurance on the dynamometer correlate at 0.958, so they are almost the same measure; the multiple correlation reported (0.816) is lower than both simple ones (0.897 and 0.871); and the stated contributions, 80.46 and 75.86 per cent, add up to more than a hundred.

  Archers split into high and low performers by k-means clustering: the better group has a higher score and higher values for height, weight, arm span and waist, hip and thigh girth; the only measure that does not separate the two groups is calf girth. The comparisons are shown only as graphs, with no test or coefficient, the chapter does not say how many archers were measured or where they came from, and the score comes from six arrows after four sighters.

  12 young Malaysian recurve archers (9 boys and 3 girls, 16.0 ± 1.6 years): in the better-scoring group median arm span is 181.0 cm against 163.6 (Z = -2.57, p = 0.010), and it is the measure most closely correlated with the score (rho = 0.822, p = 0.001). In the same sample height correlates at 0.80: with twelve archers there is no telling which of the two matters.

  23 university club archers in Jakarta, arm length 73.96 ± 2.25 cm and a score of 555.13 ± 26.01 out of 600 at 18 metres: in the path analysis arm length bears on the score with a coefficient of 0.253 (p = 0.017), 6.4 per cent of the variance, less than estimated aerobic capacity (0.520) and core endurance (0.266).

  33 Indian archers of national and international level: the arm span index is 104.8 ± 2.4, above 100 in every one of them, but it is not related to the score (r = -0.102, p = 0.571), and neither is the arm index (r = -0.188, p = 0.296). None of the eleven anthropometric measures correlates significantly with the score, with coefficients between -0.248 and 0.305.

  45 Turkish traditional archers aged 20 to 35 (25 men, 20 women): whole arm length does not correlate with the score in the women (r = 0.243, p = 0.301) or in the men (r = 0.229, p = 0.271), and no anthropometric measure is significant in either sex. The men have longer arms than the women, 76.08 against 72.08 cm.

Status history

1. 2014 Not studied The question comes close but has not yet been asked. In sixty-two national-level recurve archers draw length is only weakly linked to the score, with a direct coefficient of 0.15, and in the model it weighs more by way of technique. Draw length depends on the arms but also on technique and posture, and nobody measured arm length: on this question there is no evidence yet.
2. 2017 Reported The first direct data: in twenty-four archers from the Aceh provincial squad arm length correlates with accuracy at 0.871. The figure needs care, because in the same paper arm length and arm endurance on the dynamometer correlate with each other at 0.958, and the multiple correlation reported is lower than either of the simple ones. An association in a small group, with sums that do not add up: reported.
3. 2018 Reported A second group of archers, whose number and origin the chapter does not give, split into high and low performers by a clustering algorithm, shows that the better ones are bigger in every respect: height, weight, arm span and girths, with the calf the only exception. The comparisons are graphs only, with no test, and the score comes from six arrows. It points the same way but says more about overall build than about the arms: the status holds.
4. 2020 Reported The clearest result in favour: in twelve young recurve archers from the Terengganu state squad and a Malaysian sports school, the better shooters have a median arm span of 181 cm against 163.6 (p = 0.010), and span correlates with the score at 0.822. In the same group height correlates at 0.80, so arms and height go together. Three associations pointing the same way, all cross-sectional and all in small or undescribed groups: reported.
5. 2023 Contested Both sides arrive together. In twenty-three university club archers longer arms go with a slightly higher score at 18 metres (coefficient 0.253, p = 0.017, 6.4 per cent of the variance), less than aerobic capacity does. In thirty-three Indian archers of national and international level, by contrast, none of the eleven body measures is related to the score, and arm span exceeds height in all of them: for the span index r = -0.102, p = 0.571. The first study against, and in higher-level archers: contested.
6. 2025 Contested Two new samples, about as far apart as they could be, do not find the link. In forty-five Turkish traditional archers whole arm length does not correlate with the score in the women (r = 0.243, p = 0.301) or in the men (r = 0.229, p = 0.271), and no body measure holds up; in seventeen middle-school beginners the correlations for arm, forearm, hand and span lie between 0.080 and 0.236, none of them significant. The side against grows, but these are small groups in regional journals: contested.
