Occurrence of Weak Links of Biokinematics Chain and Pain Feeling in The Lumbar Spine in Kayakers and Female Rowers - Preliminary Observation

Małgorzata Wójcik and Idzi Siatkowski

Objectives: Determination of weak links presence in musculoskeletal system and pain feeling in the lumbar spine in kayakers and female rowers.

Methods: 40 players from Championship Sports School were tested: 8 female kayakers (FK), 12 male kayakers (MK), 13 male canadians (MC) and 7 female rowers (FR). Low and high threshold Performance Matrix Tests were used to identify the weak links of the musculoskeletal system in the lumbar spine. The analysis of weak links occurrence in biokinematics chain was performed, pain feeling was indicated in lumbar spine, the location and direction of weak links occurrence in the lumbar spine were identified and it has been examined whether it depends on gender using t-test, analysis of variance ANOVA and Tukey multiple comparison test.

Results: The average age of players was 16.00±0.99 (mean±S.D.), average length of trending period was 4.92±2.20. It has been found that there are weak links in the lumbar section of spine among the players. It has been proved that the discipline has no any influence on the weak links value in low threshold but in high threshold yes. It was noticed that the low and high threshold activity values do not affect significantly the occurrence of pain and it does not depend on sex.

Conclusions: Weak links have been noticed in the lumbar spine in all directions except extension. It was found that the choice of discipline has no significant effect on the value of the weak links in the low threshold activity and has a significant impact on the value of the weak links in high-threshold activity. The presence of weak links does not depend on gender. There was no statistical relationship between the weak links presence of high threshold in the lumbar spine and pain feeling.
