Mobility and Turkish traditional archery: Kul 2026

Twenty-four men from Bayburt University, aged between 18 and 30, with at least six months of regular practice in traditional Turkish archery, randomly allocated into two groups of twelve after the baseline measurements. The experimental group does eight weeks of postural mobility exercises with elastic bands, three sessions a week of forty to sixty minutes, which also contain the warm-up, the archery training and the cool-down. The control group continues only its archery training, at the same weekly frequency and for the same duration.

Six things are measured: grip strength with a dynamometer, thumb pinch, isometric back and leg strength with a platform dynamometer, shoulder joint position sense with eyes closed at three angles, shoulder mobility as the distance between the hands behind the back, and the score under the rules of the Turkish traditional archery federation.

In the before-and-after comparison within the experimental group all six measures improve. In the control group grip, pinch, back and leg strength and proprioception do not move, while shoulder mobility improves and, above all, so does the score, with Z equal to minus 3.243 and p equal to 0.002: eight weeks of shooting alone are enough to raise the score.

The comparison between the two groups after the intervention is the part that decides, and the authors report it. The bands leave a clear advantage on strength: grip with U equal to 23.50 and p equal to 0.005, thumb pinch with 35.50 and 0.032, back and legs with 2.50 and p below 0.001. On everything else there is no difference between the groups: shoulder proprioception with U equal to 54.50 and p equal to 0.299, mobility with 49.00 and 0.181, and the score with 51.00 and p equal to 0.221.

The abstract and the conclusions, however, recommend adding the bands to traditional training as an effective method for increasing archers' muscle strength, joint stability and performance. Of those three things, the between-group comparison supports the first and denies the other two.

A design with before-and-after measures and a control group. Allocation took place after the baseline measurements, using a computer-generated random number sequence, which among the studies on this question is an exception and deserves saying. Approval from the ethics committee of Bayburt University dated 31 March 2023, written and oral consent from everyone.

Inclusion criteria: age between 18 and 30, at least six months of regular practice in traditional Turkish archery, willingness to attend regularly, written consent. Excluded were those who had had major injury or surgery to the upper limb in the previous six months, those with a history of neurological, orthopaedic or cardiovascular disorders, and those unable to attend.

The score is the one in the rules of the Turkish traditional archery federation, recorded as a total for each participant. The shooting distance and the number of arrows are not reported.

Proprioception is active shoulder joint position sense: with the eyes closed the participant is asked to reproduce three reference angles, sixty, ninety and one hundred and twenty degrees, and the absolute angular error is measured with a universal goniometer, three times, taking the mean. Shoulder mobility comes from the mobility test of the Functional Movement Screen: standing, one arm goes up in flexion and abduction and the other down in extension and internal rotation, trying to bring the hands together behind the back, and the distance between the hands is measured, three trials and a mean.

Grip is measured with a Jamar hydraulic dynamometer seated, shoulder adducted, elbow at ninety degrees, forearm neutral, wrist between zero and thirty degrees of extension, three trials with a minute of rest; thumb pinch with a Jamar gauge in the same position, taking the mean of three trials. Isometric back and leg strength with a platform dynamometer of 61 by 61 centimetres, a range from 22 to 272 kilograms in steps of 2.25, standing with the knees slightly flexed and the trunk upright, three trials with a minute of rest, taking the highest value.

The band exercises are five and all concern the shoulder: seated external rotation with the elbows at the side at ninety degrees, pulling the band apart in front at shoulder height, seated shoulder flexion with the band under the feet, shoulder extension against the band fixed under the feet, and stability work in which the band is held still during dynamic movements. Three sets each, from eight to fifteen repetitions depending on the exercise, with intensity raised over time by changing the band's resistance or the volume.

The analysis is non-parametric, because the Shapiro and Wilk test showed the data were not normally distributed: within-group comparisons with the Wilcoxon signed-rank test, between-group comparisons with the Mann and Whitney U test, threshold at 0.05, in SPSS 26. Both kinds of comparison were carried out and reported, both before the intervention, as a baseline check, and after it.

The study was funded by Bayburt University's student research project support programme, and had already been presented at a congress in October 2024. Received on 19 September 2025, accepted on 27 April 2026, published on 22 June. A regional venue.

The flaw lies in the step from the results to the conclusions, not in the results. The conclusions recommend the bands for increasing muscle strength, joint stability and performance. The between-group comparison after the intervention, carried out and published by the same authors, gives the score at p equal to 0.221 and proprioception at 0.299: two of the three things recommended are precisely the ones their test does not find. Strength remains, where the advantage is clear. Whoever reads the abstract takes away three results, whoever reads the table finds one.

The same step covers the way the abstract describes the control group, with limited increases in mobility and score. On the score the control's increase is not limited: it carries p equal to 0.002, of the same order as the experimental group's, and this is the most important number in the study for anyone wanting to know whether bands make points. Eight weeks of shooting alone raise them on their own.

In the two between-group tables, the groups are called by names that do not exist in this study. The results text and the title of Table 3 speak of elite and amateur archers, while the study has an experimental and a control group drawn by lot from twenty-four university students with at least six months of practice. From the context it is clear the comparison is between experimental and control, since the one before the intervention is the usual baseline check, but a reader who stops at those two pages reads about different research.

Three pairs of Z and p, out of twelve reported in the text, do not hold together. Back and leg strength in the experimental group has Z equal to minus 2.699 with p given as 0.036, while that value corresponds to 0.007; mobility in the control group has minus 2.819 with p given as 0.036 against 0.005; grip in the control group has minus 0.892 with p given as 0.112 against 0.372. The other nine pairs sit within a factor of 1.7, consistent with the difference between an exact test and the normal approximation on twelve people, while these three depart by five, seven and three times, in opposite directions: they are therefore transcription errors rather than a choice of method. None of the three changes a conclusion, since in all three cases the result falls on the same side of the threshold with either value.

On the design three things remain. Shoulder mobility already differed between the groups at baseline, at p equal to 0.061, and it is also one of the outcome measures: on that one the final comparison starts from a difference. The experimental group trained under supervision and the control did not, so the attention received is an uncontrolled difference, and whoever delivered the exercises also took the measurements. And the durations are declared equal, forty to sixty minutes, but the experimental group's session contains the warm-up, the bands and the cool-down within that time: at equal minutes, that group probably shot fewer arrows than the control, and the study reports how many neither group shot.

One result deserves a reservation for its size. Back and leg strength separates the two groups almost completely, with U equal to 2.50, while the five band exercises all concern the shoulder. The test consists of pulling a handle upwards while standing on a platform, and it is a movement that is learned: eight weeks of supervised practice and a second sitting of the test explain part of that separation at least as well as a gain in back and leg strength obtained by working the shoulders.

Finally the reach. Twenty-four men from a single university, all in traditional Turkish archery, with at least six months of practice and no indication of competitive level; no sample size calculation; and the shooting test with neither distance nor arrow count, so the score cannot be compared with any other study. Traditional Turkish archery is not shot like Olympic recurve, in grip, release and distances, so the transfer to recurve and compound is an open question rather than a datum.

This is one of the few studies on this question built the right way, and that makes its answers count for more than others'. The groups were drawn by lot, the control group carried on shooting at the same frequency, and the between-group comparison was made and published rather than promised in the methods and forgotten in the results.

And the answer is twofold. Eight weeks of shoulder band work, three times a week, give more strength: grip, thumb pinch and back and leg strength rise compared with those who only shot. On the score, no: there is no difference between the groups, at p equal to 0.221. Nor on shoulder proprioception and mobility, where the groups end up level.

The most instructive thing, for a reader of the registry, is the control group. Those who only shot also raised their score, at p equal to 0.002: all twelve of them. This is exactly why studies that measure only before and after, with nothing to compare against, always find improvements and say nothing about the intervention. Eight weeks of practice raise the score on their own, and an intervention has to be judged on how much better it does than that.

So what does an archer take from it. Bands are a practical and inexpensive way of getting stronger, and this study shows it with a clean comparison. That the strength turns into points, within eight weeks and at this sample size, is not visible. It is not evidence that they never help, because twelve people per group and a single eight-week block are not enough to rule out a small effect; it is evidence that the gain in points is neither immediate nor automatic.

The registry keeps this work as the firmest design available on elastic bands, with a null result on the score in the between-group comparison and a positive result on strength, in traditional Turkish archers, and notes that the article's conclusions also recommend performance and joint stability, which its own tests do not find.
