Effect of high protein diet in activity of antioxidants and level of inflammation on sprint athlete

This study aims to analyze the effect of a low-carbohydrate high-protein diet to increase the level of antioxidant, decrease inflammation and improve performance of athlete. The research was carried out by experimental research methods, within the design of “Randomized Control Group Pretest Posttest Design”. A sample was taken from 20 people who met the inclusion and exclusion criteria from 30 teenage athletes in PASI East Java sprints. The Data were collected by measuring the sprint results by finish photo camera and laboratory examinations to determine the levels of antioxidants (SOD) and the inflammation degree (TNF-α) in blood. The data were analyzed using multivariate technique (Manova) Hotelling’s method (T2). Hypothesis testing using α = 0.05. The results and conclusions of the study stated that the normal diet had no effect on the variables of sprint running speed, SOD and TNF-α levels. While low-carbohydrate and high-protein diet can increase SOD levels of 211.44/gHb, reduce (TNF-α) at least 0.309 pg/ml, and the average increase in antioxidant activity caused by low-carbohydrate-high-protein diet is 24.989/gHb higher than normal diet, the decrease in the degree of inflammation is 0.196 pg/ml, however, it has no effect on the speed of sprint.

Space for self-expression: communication of Czech female athletes on social media and fansʼ reactions

Social media platforms allow athletes to share information with the public. This opportunity is arguably more important for female athletes who traditionally receive less space in the mainstream media than their male counterparts. This article focuses on the social media self-presentation of six successful, internationally recognized, professional Czech female athletes and their fans’ reactions. By using qualitative and quantitative content analyses, it was revealed that throughout the season, the selected athletes presented themselves as powerful professionals, while their off-season posting tended to be more personal and, for the most part, more feminine. Contrary to previous research, fans did not frequently respond with explicitly sexual or negative comments. Moreover, they supported and admired the athletes, and in most cases, reacted positively. A higher sensitivity was indicated in relation to the sportswomen’s personal relationships and opinions. This leads us to the conclusion that social media enables professional female athletes to present themselves more freely than traditional media and be positively received by the public.

Clinical evaluation of shoulder ROM in volleyball and handball players in youth categories

Aims. The aim of this study was to clarify whether volleyball and handball players, as representatives of the so-called overhead athletes, already have an increased ROM and specific local hypermobility in the shoulder joints in the junior categories. These changes are described by goniometric measurements and hypermobility tests according to Sachse and Beighton. The results are examined with respect to gender and sport specialization. Methods. Ninety-five subjects without previous shoulder joint injury aged 16 to 19 years, including 73 volleyball and handball players, were tested. The cohort included 33 men, 40 women, 34 handball players and 39 volleyball players. The control group consisted of 22 participants, including 11 men and 11 women. The majority (90.5%) of the study participants were right-hand dominant. Only 9.5% of the participants were left-handed. Measurements were taken with a goniometer with digital display and hypermobility tests according to Sachse and Beighton. Results. In a selected group of volleyball and handball players, the ROM of the shoulder joints of the dominant arm was significantly greater in three ways: into extension, horizontal adduction and external rotation. On the other hand, the ROM of their shoulder joints in internal rotation is smaller and the research group has significant hypermobility in the glenohumeral (scapulohumeral) joint compared to the control group. Our study showed that females compared to males playing volleyball and handball have a significantly higher degree of internal rotation of both dominant and non-dominant arms. No significant differences were found when comparing volleyball and handball players. The difference in ROM between the dominant and non-dominant arms of volleyball and handball players was shown in extension and external rotation.

Market potential of TikTok in the context of the communication range of soccer players on social networks

The study aims to put the social network TikTok into the context of the marketing attractiveness and potential of soccer players in terms of communication range through social networks. Soccer clubs can assess the expenses of gaining additional followers through a purchased player by an evaluation of the market efficiency of individual soccer players’ followers. The study also documents positive effects ensuing from the acquisition of further followers thanks to the purchase of such a player including image, connection with fans, global reach, additional external funds through sponsorship and the sale of television rights, loyal fans and other so-called “extra-football qualities”. The study thus brings new perspectives on TikTok, as a network which has so far not been thoroughly researched, in the field of the most popular sport in the world, soccer.

Considering the youth voice: needs and asset assessment in sport for development using photovoice

With the growth of sport for development (SFD), it is increasingly important to ensure that programmes are intentionally designed to meet the needs of the communities they serve, in a way that helps build community capacity. Still, many programmes have been criticised for not considering the voices of marginalised individuals, specifically youth programme recipients, in the planning and development of SFDprogrammes. Additionally, programmes are developed from a deficit approach where only the needs or negative aspects of the community are being considered in the planning and development of programming. With these issues in mind, the purpose of this study was to assess the usefulness of photovoice as a strategic tool to give youth a voice in SFD needs and asset assessment. Additionally, it examined how practitioners can utilize the outcomes of a needs and asset assessment in planning and implementing SFD programming. The results highlight the assets and challenges that the youth participants identified and the practical use of the assessment from the perspective of programme administrators. The results suggest that photovoice can allow youth programme participants to have a genuine voice in programme development.
