Clinical Trial Summary

The aim is to assess the influence of asymmetric training on the locomotor system in sweep rowers. To analyse possible changes objectively, the axial position of the hull will be assessed using Moiré topography, and the symmetry of foot loading will be monitored with a pedobarograph. Furthermore, the Visual Analog scale and Cluster of Laslett will determine whether an asymmetric load can provoke pain in the lumbar region or cause a blockage in the SI joint. In the experimental study, there will be three different groups of participants. Selected sweep rowers will make the first study group. The second group will consist of scull rowers, and the last control group will consist of people with no experience with rowing. The selected participants will undergo the first measurement at the turn of the spring and summer seasons when intensive preparation for rowing competitions begins, in which sweep rowers train mainly on water and asymmetrically. The measurement results in the three groups will be further compared with each other to evaluate whether statistically significant differences can be found.

Description:

Methods: 21 sweep rowers, 20 scull rowers and 23 non-rowing peers were enrolled on the study of this diploma thesis. Each subject was assessed using DIERS formetic 4D and DIERS pedoscan devices. Additionally, participants in each group were assessed by FAIR test, Cluster of Laslett, trigger point palpation of the m. piriformis and Visual analogue scale were used to assess pain intensity in the lumbar region.
