    COMPARISON OF COMPETITIVE ACTIVITY INDICATORS AT 100 M DISTANCES OF LATVIAN AND EUROPEAN SWIMMERS
    (Rēzeknes Tehnoloģiju akadēmija, 2023-07-03) Jakubovskis, Germans; Solovjova, Jelena; Zusa, Anna; Danilāne, L.; Laganovska, K.; Strode, A.; Kaupužs, A.; Znotiņa, D.; Latvian Academy of Sport Education (LASE)
    The research aimed to study the performance characteristics of male and female finalists at a 100m distance when swimming at the Latvian swimming championships in a period from 2018 to 2020 (in the 50m pool).262 final heats got analyzed. The results of the 3 best Latvian swimmers, males=36, and females-36, at each 100m distance (freestyle, breaststroke, backstroke, and butterfly) at championships in 2018, 2019, and 2020 have been analysed. The parameters for overcoming competitive distance:competitive result in the 100-meter distance; the start reaction time; time forthe 15 meters mark; speed to the 15 meters mark; the time of the turn 5 meters up to the wall and 15 meters after the turn; underwater distance and time after the start and after turning; time of “clear” swimming. The obtained results were compared to the characteristics of overcoming the same competitive distance by the finalists of the European Championship 2016. As a result of comparative analysis, statistically, significant differences were found in such parameters of competitive activity as the overall result, overcoming of starting and turning parts, and the distance covered under water after the turn and start. Statistically significant differences were not found in the reaction time to the start signal and in the speed of “clear” swimming. The comparative analysis of the performance characteristics of the European Championships finalists showed possibilities for further improvements of Latvian swimmers.The aim: is to determine the performance parameters of the Latvian best swimmers and compare them with the same parameters of the finalists of the European Championship 2016.

    Effect of different sports on young athlete's posture swimmers and cyclists
    (2023-08-30) Solovjova, Jelena; Boobani, Behnam; Grants, Juris; Jakubovskis, German; Avotina, Ilze; Obminski, Zbigniew; Litwiniuk, Artur; Latvian Academy of Sport Education (LASE)
    Background & Study Aim: In each sports discipline morphological characteristics, elements of technical, tactical, and psychological preparation can be distinguished whose high level may affect sports results. The aim of this study is knowledge about the express diagnostic program and the possibility of detecting changes in musculoskeletal posture in young athletes practicing various sports disciplines. Material & Methods: The participants were 38 athletes from sports clubs in Riga, Latvia, swimmers (n = 19), and cyclists (n = 19) aged 14-15 years old with experience in National competitions. Body posture was assessed once before the training for visual diagnostics and muscular functional testing. A diagnostic program was developed from these methods, which included measuring the changes of 8 sagittal points from the vertical plane and functional testing of 8 muscle groups. The analyses were conducted using IBM SPSS version 26. The Shapiro-Wilk test, an independent t-test and the Mann-Whitney U test were used to analyse the data. Results: The results showed that both groups (n = 38); standing posture was falling forward. There were significant differences between the two groups. Cyclists demonstrated significant results than swimmers for the following posture indicators - External Ear Opening (EEO), Radial Point (RP), Highest Point of the Iliac Crest (HPIC), M. Pectoralis Major Upper part (MPMU), Outer Points of the Palm (OPP), Acromion (ACR), Trochanter (Tro), Upper End of Fibula Bone (UEFB), M. Rectus Abdominis (MRA) and Blade Fixators (BF). There were significant results for swimmers in M. Quadriceps Femoris (MQF) and M. Gluteus Medium (MGM) at the 5% level. There was not a significant difference between the two groups in Hamstring Muscles (HM) and for M. Iliopsoas (MI). Conclusions: It can be concluded that each sport leads to postural changes in athletes due to specific functional muscle changes, as the results highlighted changes in both groups. Early postural changes in young athletes can be identified by applying express diagnostics. Early detection should lead to the prevention of injury.
