Yoga and attention in archers: Yadav 2022 study

Fifty archers aged 18 to 25, split into two groups of 25, kept up their usual two hours of shooting a day for 12 weeks; one group also did an hour of yoga every day built around three practices: Bhramari breathing, Trataka (gazing at a point or a flame) and Jala neti (rinsing the nose with water). The authors measure attention in two ways: with a shooting score and with the number of errors on a mirror-tracing task.

The shooting score rose in both groups, more in the yoga group: from 69.56 to 102.88, against a rise from 66.72 to 78.80 in the controls, a gain of 33.32 points against 12.08. Errors on the mirror task fell from 30.76 to 18.72 in the yoga group and from 29.84 to 23.64 in the controls. The authors report a t of 8.30 for shooting and 7.192 for errors, and conclude that yoga increased the archers' attention.

The authors describe the design as a randomised pre-post experiment but do not explain how the allocation was done. The experimental group did yoga six days a week with an instructor and on the seventh day alone; the programme table lists 20 minutes of Bhramari every day, 20 minutes of Jala neti on Monday, Wednesday and Friday and 20 of Trataka on Tuesday, Thursday and Saturday, plus ten minutes of mobility exercises and ten of basic postures. The control group only shot.

The shooting test was six arrows at each of three targets, at 18, 20 and 25 metres (the text also gives the second distance as 22 metres), with five minutes per target. The target face had five zones with English imperial scoring: 9 for gold, 7 for red, 5 for blue, 3 for black and 1 for white. With 18 arrows the maximum is 162 points. The eye-hand coordination test is the classic mirror-tracing task: following the outline of a star with a stylus while seeing it only in a mirror, within two minutes, with errors counted. The authors say they also recorded time, but report only errors. The type of bow, the archers' level and their experience are not given.

The difference between the groups is not only yoga: for three months the experimental group had an extra hour a day of guided activity with an instructor, and the controls did not spend an hour on anything else to balance the time. It is not stated whether the people scoring the arrows or counting the errors knew which group each archer was in. The three practices were given together, and alongside mobility exercises and postures, so even a real effect could not be attributed to any one of them.

The statistical analysis is described unclearly. The "required" t values the authors compare theirs against (5.307 and 3.571) do not match the usual threshold for two groups of 25, which is around 2, and the table notes give yet other thresholds (1.857 and 1.534). The text speaks of an independent t-test, but the tables report a t for each group together with a before-after correlation (3.45 for shooting and 2.037 for errors in the controls): these look like before-after comparisons within each group, and no direct test of the difference between groups appears. There are other inconsistencies: the abstract says the archers came from Bhopal, the methods from a college in Udaipur, and the second shooting distance is given as both 20 and 22 metres. That a score on 18 arrows at short distances and a mirror test measure attention is an assumption of the authors, not something the study checks. The journal is flagged in the registry for questionable editorial standards.

The study does not allow anyone to say that Bhramari, Trataka or nasal rinsing improve shooting. It shows that archers who added an hour of guided yoga to their shooting for three months improved their score on 18 arrows at short range more than those who only shot, but the comparison leaves too many explanations open: the extra time, the presence of an instructor, the motivation of knowing you are in the treated group.

Nothing here tells archers who already use yoga or breathing exercises in their preparation to stop; anyone looking for a measured reason to start will not find it in this paper. The shooting result also comes from distances of 18 to 25 metres on an imperial-scored target face, and says little about competition at Olympic distances.
