Darba stress un biomehāniskie riska faktori profesionālajā sportā, to samazināšanas iespējas
2017
„Darba stress un biomehāniskie riska faktori profesionālajā sportā, to samazināšanas iespējas”. Darba autore: Ieva Tetere. Zinātniskais vadītājs: Dr.sc.admin., asoc.prof. H. Kaļķis. Darba apjoms ir 98 lpp., tajā ietvertas 10 tabulas, 36 attēli, 5 pielikumi un 34 literatūras avoti. Darba stresa un biomehānisko riska faktoru ietekmē profesionālie sportisti var izjust psiholoģiska rakstura diskomfortu un tikt pakļauti augstam sporta traumatisma riskam, bet Latvijā no darba aizsardzības aspekta tā ir maz pētīta tematika. Darbs sastāv no 4 daļām, kuru ietvaros veikta literatūras izpēte, izvēlēto metožu raksturojums, iegūto rezultātu analīze, izstrādāti priekšlikumi un aizsardzības pasākumi. Maģi…
Modulations of corticospinal excitability following rapid ankle dorsiflexion in skill- and endurance-trained athletes
2022
Abstract Purpose Long-term sports training, such as skill and endurance training, leads to specific neuroplasticity. However, it remains unclear if muscle stretch-induced proprioceptive feedback influences corticospinal facilitation/inhibition differently between skill- and endurance-trained athletes. This study investigated modulation of corticospinal excitability following rapid ankle dorsiflexion between well-trained skill and endurance athletes. Methods Ten skill- and ten endurance-trained athletes participated in the study. Corticospinal excitability was tested by single- and paired-pulse transcranial magnetic stimulations (TMS) at three different latencies following passive rapid ankl…
Does Stretching Training Influence Muscular Strength? A Systematic Review With Meta-Analysis and Meta-Regression
2022
Thomas, E, Ficarra, S, Nunes, JP, Paoli, A, Bellafiore, M, Palma, A, and Bianco, A. Does stretching training influence muscular strength? A systematic review with meta-analysis and meta-regression. J Strength Cond Res XX(X): 000-000, 2022-This aim of this study was to review articles that performed stretching training and evaluated the effects on muscular strength. Literature search was performed using 3 databases. Studies were included if they compared the effects on strength following stretching training vs. a nontraining control group or stretching training combined with resistance training (RT) vs. an RT-only group, after at least 4 weeks of intervention. The meta-analyses were performe…
5-6 gadīgu bērnu simetriskas stājas veicināšana sporta nodarbībās
2019
Kvalifikācijas darba temats ir – ’’5-6 gadīgu bērnu simetriskas stājas veicināšana sporta nodarbībās’’, darba autore Marina Bulajeva. Kvalifikācijas darba mērķis ir teorētiski analizēt un praktiski pētīt 5-6 gadīgu bērna stāju un tās veicināšanu sporta nodarbības. Darbs sastāv no teorētiskās un empīriskās daļas. Teorētisko atziņu izpēte tika veikta balstoties uz pedagogu un psihologu atziņām par simetriskās stājas nozīmi, stājas veidošanās traucējumiem un ietekmējošiem faktoriem, simetriskās stājas sekmēšanu sporta nodarbībās. Empīriskajā daļā darba autore veic praktisku pētījumu, kā sekmēt simetriskas stājas veidošanos sporta nodarbībās. Pētījumā tika izmantotas tādas metodes kā, vecāku an…
Longbordistu subkultūra Rīgā
2018
Bakalaura darba tēma ir „Longbordistu subkultūra Rīgā”. Tēmas aktualitāte –longbordošana un longbordisti vispār līdz šīm nav pētīti, kā arī Rīgā longbords ir kļuvis populārs un aktuāls pēdējos četrus gadus. Tāpēc šī pētījuma mērķis ir izpētīt longbordistus kā subkultūru Rīgā. Pētnieciskais jautājums ir: Kādas ir longbordistu galvenās subkultūras iezīmes? Teorētiskajā daļā tiks apskatīts subkultūras jēdziens, tiks skaidrots dzīvesstila jēdziens, longbordošanas vēsturiskā attīstība, longborda braukšanas veidi, kā arī, kā longbords iekļaujas starp ekstrēmiem sporta veidiem. Bakalaura darbā izmantotas kvalitatīvās metodes. Tika veiktas intervijas – padziļinātās ar ekspertiem, daļēji strukturētā…

A Polygenic Risk Score for Hand Grip Strength Predicts Muscle Strength and Proximal and Distal Functional Outcomes among Older Women
2022
Purpose Hand grip strength (HGS) is a widely used indicator of overall muscle strength and general health. We computed a polygenic risk score (PRS) for HGS, and examined, whether it predicted muscle strength, functional capacity and disability outcomes. Methods Genome-wide association study summary statistics for HGS from the Pan-UK Biobank was utilized. PRSs were calculated in the Finnish Twin Study on Aging (N = 429 women, 63–76 years). Strength tests included HGS, isometric knee extension, and ankle plantar flexion strength. Functional capacity was examined with the Timed Up and Go, six-minute and 10-meter walk tests, and dual-task tests. Disabilities in the basic (ADL) and instrumental …
Coaches’ Perceptions of Athletes’ Psychobiosocial States : The Case of Three Tennis Coach-Athlete Dyads
2018
Considering the limited attention paid to interpersonal aspects of emotions, this study explored coaches’ perceptions of athletes’ performance-related states and how they used this information for its regulation. Using a case study approach, three coach-athlete dyads from competitive tennis took part in one-on-one semi-structured interviews. Individualized profiling of psychobiosocial states was used to assess athletes’ states in most and least successful performances and as a way of data triangulation. Findings indicated that the coaches paid attention to bodily, motor-behavioural, and operational components of a performance state, and used this information to appropriately adapt their res…
Perfectionism and performance-related psychobiosocial states: The mediating role of competition appraisals.
2022
Using the multi-states (MuSt) theory as a framework, the present study focused on the individual (personality) antecedents of psychobiosocial states. Psychobiosocial states comprise emotional subjective experiences and their correlates (cognitive, motivational, volitional, bodily, motor-behavioural, operational, and communicative), that can be functional for performance (helpful) or dysfunctional (harmful). Specifically, we examined the relationships between two perfectionism dimensions (perfectionistic strivings and concerns) and functional and dysfunctional psychobiosocial states. The hypothesised mediational role of competitive appraisals was also tested. Participants (N = 271, 138 femal…
Effects of a home-based, exergaming intervention on physical function and pain after total knee replacement in older adults : a randomised controlled…
2023
ObjectivesTo investigate the effects of 4 months of customised, home-based exergaming on physical function and pain after total knee replacement (TKR) compared with standard exercise protocol.MethodsIn this non-blinded randomised controlled trial, 52 individuals aged 60–75 years undergoing TKR were randomised into an exergaming (intervention group, IG) or a standard exercising group (control group, CG). Primary outcomes were physical function and pain measured before and after (2 months and 4 months) surgery using the Oxford Knee Score (OKS) and Timed Up and Go (TUG) test. Secondary outcomes included measures of the Visual Analogue Scale, 10m walking, short physical performance battery, iso…
