Deviant Behaviour In Competitive Sport. A Sociological Attempt At Explaining The Phenomenon, Zbigniew Dziubinski Mar 2022

Deviant Behaviour In Competitive Sport. A Sociological Attempt At Explaining The Phenomenon, Zbigniew Dziubinski

Baltic Journal of Health and Physical Activity

This article seeks to use selected sociological theories to account for the phenomenon of deviance in sport. Two main theoretical approaches are employed herein: the functionalist/structuralist approach and symbolic interactionism. The analysis that follows leads to the conclusion that deviance which occurs in sport is predominantly a consequence of deviance in modern societies. Sport, in turn, is just a convenient area for deviant behaviours to be manifested, which often happens more clearly and conspicuously than in societies.

Different Forms Of Swimmers’ Final Weeks Pre-Competition Preparation, Kamil Sokolowski, Marek Strzala, Arkadiusz Stanula

Baltic Journal of Health and Physical Activity

The pre-competition training phase is a period that precedes the main competition. Combined training phases of overload training (OT) and taper (TP) create the most popular pattern of final form preparation among the swimmers despite the methodology difficulties faced by coaches. In the IPC, the duration and training load were strictly set. The main purpose of training in the IPC is to cause a substantial supercompensation effect by the high volume and capacity of the training. However, high volume and intensity fluctuations typical of the IPC may cause performance regression due to overtraining and exhaustion. The main aim of the …

Assessment Of Physical Fitness Among Non-Athlete Adolescents: Effect Of Familiarization Sessions, Diogo Henrique Constantino Coledam, Rodrigo Dias Caria De Oliveira

Baltic Journal of Health and Physical Activity

Background: ‪The validity and reliability of fitness tests are described in the literature; however, the effects of familiarization sessions on motor performance have not yet been studied. The aim of this study was to analyze the effects of four familiarization sessions on physical fitness performance among adolescents. Material and methods: ‪Twenty adolescents performed sprint, agility, flexibility, explosive strength, muscular endurance, and balance tests on four separate days with an interval of 72h. Results: ‪Considering the first and the fourth sessions, there were significant differences in mean values for push-up, curl-up, and Flamingo tests (p<0.05). Intraclass Correlation Coefficient (ICC) varied from 0.65 to 0.97, except for the Flamingo test (0.22). The magnitude based inference revealed a likely beneficial effect of familiarization on agility (87.8%), push-ups (91.2%), curl-ups (94.4%), and a very likely effect on the Flamingo test (97.0%). When comparing the second and the third sessions with the first one, values of ICC were similar or higher, while a likely beneficial effect of familiarization was found in the second session for the Flamingo test (78.8%), and in the third session for curl-ups (91.3%), push-ups (77.1%), and the Flamingo test (94.8%). Conclusions: ‪The familiarization procedure should be considered prior to agility, muscular endurance, and balance test assessments.

Baltic Journal of Health and Physical Activity

Bone tissue is a mineralized structure with a complicated metabolism and due to its mechanical functions its structure must be adapted to the bone function. The BMP protein group stimulates the formation of bone and cartilage and influences numerous non-osteogenic processes. As a result of their osteogenic effect, BMP proteins are used in numerous areas of medicine, including dentistry and orthopaedics, as well as sport and rehabilitation. The publications used in this paper were sourced from the PubMed and the Google Scholar databases. The index entries used to search the databases included BMP, bone morphogenetic proteins, medicine, dentistry and sport. …

Exercise − A Unique Endogenous Regulator Of Irisin, Bdnf, Leptin And Cortisol Against Depression, Gilmara Gomes De Assis, Pawel Cieszczyk

Baltic Journal of Health and Physical Activity

Depression is the most prevalent stress-related disorder affecting the population world-wide with potential for an eminent increase after the 2020 pandemic. The mechanisms through which metabolism is involved in depression and stress disorders have been extensively investigated. However, their assessment using exogenous measures is a current limitation. Exercise, as is well reported in animal studies, exerts a critical regulatory influence on the main factors known to participate in these mechanisms. This overview describes the role of cortisol, leptin, irisin and BDNF in the exercise physiology and the known mechanism through which these factors act in anti-depressant mechanisms. Furthermore, the exercise …
