Överpronation kopplad till ryttarens sits
According to “Fotförbundet" (2012), Overpronation occurs frequently (80 %) in the Western World and furthermore overpronation of calcaneus influences the position of the pelvic and thorax (Fotförbundet, 2012; Behnke, 2008).

| Sumario: | According to “Fotförbundet" (2012), Overpronation occurs frequently (80 %) in the Western World and furthermore overpronation of calcaneus influences the position of the pelvic and thorax (Fotförbundet, 2012; Behnke, 2008).
The aim of this study is to investigate whether or not it is possible to connect overpronation of calcaneus to the problem in the rider’s seat as observed by the instructors of Strömsholm. The study will also investigate if the riders seat problems as noticed by the riding instructors are comparable with the problems found by the analyst during testing. One purpose with the study is to raise the instructors and riders awareness that anatomical deviations in the rider might influence the rider’s position in the saddle.
The questions of the study are:
- Is it possible to see seat problems in riders with overpronation of calcaneus?
- If it is possible to see more seat problems in riders with overpronation of calcaneus, do the instructors in the study considers the seat problems be similar with each other?
- If there are seat problems in the study, is it the same according to the instructors and the analyst in human biomechanics?
The hypothesis of the study is that overpronation of calcaneus has an effect of the rider’s position in the saddle.
The study is conducted as a blind study where the test subjects have been filmed (from knees down) as they walked barefooted and later while riding. Thereafter they were sorted into a control group and a test group. These films have later been judged by riding instructors currently active at “Ridskolan Strömsholm” as well an analyst in human biomechanics with 15 years of experience from the National Norwegian Olympic Team. The instructor’s and the analyst’s score were added together and an average for the control group and one for the test group was found.
The result shows a significant difference between the riding instructor’s score on the control group and the test group respectively. The average score of the test group is 5,8 whereas the average from the control group is 6,8. This generates a significant difference at p<=0.00235.
Given the significant difference in the score of test and control groups of the two instructors it is possible that overpronation of calcaneus have impact on the rider's seat. Although the analyst in human biomechanics has used a broader scale than the instructors, it was still the control group higher scored following average values which somewhat proves the study's conclusion on that overpronation of calcaneus can affect the rider's seat. In more than half of the test persons assessors are also consistent in their comments about the rider’s seat problem. Given the large significant difference in instructor’s and the analyst’s score of the control and test group should study's hypothesis be accepted. However, is necessary to include that the effects of different levels of the test and control groups does not depend on what level the instructor’s and the analyst is present. There is not a significant interaction between the test and control groups and instructor’s and the analyst. Therefore taken the result of the study into account the hypothesis at present neither can be accepted nor rejected. |
