383. The acute effect of mental fatigue on strength endurance in young kickboxersEsra Kürkcü Akgönül, Gökmen Özen, 2024, izvirni znanstveni članek Povzetek: This study was conducted to examine the acute effects of Mental Fatigue (MF) on strength endurance in well-trained young kickboxers. A total of 17 female/male athletes (age: 15.76±1.44 years; height: 167.06±8.63 cm; body weight: 62.03±10.63 kg) par-ticipated. The Repeated Measurement Design was used. Accordingly, the participants had 3 sessions; pre-preparation, control, and mental fatigue. In the pre-preparation session, demographic information and one repetition maximum (1RM) for bench press (BP) and squat (SQ) exercises were taken. The athletes’ strength endurance was perfor-med until 60% of 1RM exhaustion; the number of repetitions (NOR) and movement time (MT) were recorded. In the MF session, the participants were subjected to a 30-minute Stroop task before the strength test. In order to determine the differences in NOR and MT between the sessions and the differences in measurements according to gender, the Paired sample t-test was used. The presence of MF significantly reduced SQ-NOR by 34.5%, SQ-MT by 36.88%, BP-NOR by 22.71%, and BP-MT by 28.27% (p<0.05). Based on gender, MF had a significant negative effect on SQ-NOR, SQ-MT, and BP-MT in women and men and on BP-NOR only in women athletes (p<0.05). As a result of the research, 30-min MF application negatively affects the lower and upper extremity strength endurance performance in young kickboxers. In this respect, young kickboxers should avoid activities that will cause mental fatigue such as using digital screens or solving questions or puzzles for social media purposes for 30 min or more before train-ing and competition, which will prevent possible muscular performance loss.

384. Dietary habits of shooting athletes : a comparative study of Slovenian and foreign athletesTadeja Jakus, Nika Černe, Mojca Stubelj, 2024, izvirni znanstveni članek Povzetek: Purpose: Shooting is a sport in which dietary habits and the timing of meals is not often represented. The aim of this paper is to compare the dietary habits, timing of meals and training frequency of Slovenian and foreign athletes. Methods: The sample included 88 shooter athletes (35 Slovenian and 53 foreign athletes), aged 14 to 60, who participate in competitions. Data by dietary habits, diet, training and BMI were collected via a questionnaire. Results: Athletes train and compete most frequently using an air rifle. Foreign athletes train more often and spend more time training than Slovenian athletes (p < 0.001). The average BMI was 24.9 ± 4.9 kg/m2 and was higher in athletes who competed at national level (26.8 ± 5.6 kg/m2) compared to international level (23.0 ± 3.1 kg/ m2) (p = 0.022). We found a difference between the groups in lunch (p = 0.041), morning (p = 0.020) and evening (p = 0.008) snacks. Slovenian athletes reached for food during training less frequently than foreign athletes (p = 0.007). More than half of the athletes (p < 0.001). Conclusions -athletes tend to train more frequently, have better nutritional planning and eat more meals after training than their Slovenian counterparts.

385. Physical characteristics as indicators of performance in young alpine skiers in Super-GStojan Puhalj, Blaž Lešnik, Črtomir Matejek, Samo Fošnarič, Tjaša Kmet, Jurij Planinšec, 2024, izvirni znanstveni članek Povzetek: Purpose: The aim of this study is to determine the relationship between physical characteristics and performance in young alpine skiers in the Super-G discipline. Methods: A sample of 42 U16 alpine skiing competitors (23 boys and 19 girls) aged 14-15 years participated in the study. The physical characteristics were measured using the Inbody 720 Body Composition Analysis and 3D Body Scan devices. Performance data was obtained from official records of the Ski Association of Slovenia for the 2018/19 U16 competitive season. Variables such as body height, body weight, thigh circumference, waist circumference, chest circumference, shoulder circumference, muscle mass percentage, fat mass percentage, body mass index, and body fat percentage were analyzed. Pearson correlation coefficients and multiple regression analysis were used to assess the relationship between the physical characteristics and Super-G performance. Results: Significant correlations were found between body weight, thigh circumference, chest circumference, muscle mass percentage, and Super-G performance in boys. For girls, waist circumference, chest circumference, and body fat percentage were significantly correlated with performance. The multiple regression model explained 73% of the variance in the boys’ performance and 59% in the girls’, although the model itself was not statistically significant for predicting performance. Conclusion: Physical characteristics, especially muscle mass percentage and body circumferences, are significantly associated with Super-G performance in young alpine skiers. These findings underscore the importance of tailored training programs that consider individual physical characteristics to optimize competitive success in alpine skiing.

387. Productivity, pressure, and new perspectives : impacts of the COVID-19 pandemic on marine early-career researchersAmanda Schadeberg, Eleanor Ford, Alina M. Wieczorek, Louse C. Gammage, María López-Acosta, Ivana Buselic, Timotej Turk Dermastia, Marcos Fontela, Cristina Galobart, Natalia Llopis Monferrer, Marek Lubośny, Stefania Piarulli, Giuseppe Suaria, 2022, izvirni znanstveni članek Povzetek: The worldwide disruption caused by the beginning of the COVID-19 pandemic has dramatically impacted the activities of marine scientists working towards the goals of the UN Ocean Decade. As in other disciplines, marine early-career researchers (ECRs) are essential contributors to the development of novel and innovative science. Based on a survey of 322 of our peers, we show that the pandemic negatively impacted marine ECRs in ways that further exacerbate existing structural challenges such as social isolation, job insecurity, and short-term contracts, competitive funding, and work pressure. Furthermore, we find that the success and wellbeing of marine ECRs depends heavily on networking opportunities, gaining practical experience, collecting data, and producing publications, all of which were disrupted by the pandemic. Our analysis shows that those in the earliest stages of their careers feel most vulnerable to long-term career disadvantage as a result of the pandemic. This paper contributes to the empirical body of work about the impacts of the pandemic on marine science and offers recommendations on how marine ECRs should be supported to achieve the UN Ocean Decade’s goal of producing “the science we need for the ocean we want”.

388. Best practice manual for national decade committeesstrokovna monografija Povzetek: 2023 marks the beginning of the third year of the UN Decade of Ocean Science for Sustainable Development, and we are now at a moment in time where we can start taking stock of the Ocean Decade’s early achievements. The critical role that National Decade Committees are playing at the junction of the global momentum of the Ocean Decade and the national transformation of ocean science is clear and extremely encouraging. I warmly congratulate those Member States that have led by example and created the first cohort of National Decade Committees. This Best Practice Manual for National Decade Committees is an opportunity to celebrate their dynamism, share their vision and successes, and encourage the establishment of new Committees across all 150 IOC/UNESCO Member States. The ambition of the Ocean Decade is to transform ocean science for the decades to come, thereby creating a step change in the relationship of all citizens to the ocean, and in the way that a healthy ocean contributes to sustainable development. National Decade Committees are essential to catalyse the transformation of ocean science by boosting national capacity to offer solutions to pressing challenges and working across the science-policy-society interface to inform decision makers and society at large. By bringing together diverse stakeholders and breaking down silos, National Decade Committees create a tangible and visible difference on the ground. Beyond their role to coordinate existing initiatives and catalyse new Decade Actions, National Decade Committees embody the core principles of the Ocean Decade including equity, inclusivity, and diversity, and the recognition of the importance of Indigenous and local knowledge systems. They have a particularly significant role in giving a seat at the table to Early Career Ocean Professionals, who will be the torch bearers of the legacy of the Ocean Decade post-2030.I hope that the diverse and rich experiences shared in this Manual will inspire many other Member States to actively participate in the Ocean Decade by setting up their own National Decade Committees. The existing cohort of National Decade Committees and the IOC/UNESCO stand ready to facilitate the involvement of new partners, while supporting the pioneers to go even further, and thus together achieve a key goal of the Ocean Decade to make sure no one is left behind in the endeavour to create the ocean we want by 2030.

389. A checklist of isopods (Crustacea: Isopoda) in SloveniaMiloš Vittori, Borut Mavrič, Anja Pekolj, Marijan Govedič, Maja Zagmajster, 2023, izvirni znanstveni članek Povzetek: Isopods are a diverse peracarid crustacean group with marine, freshwater and terrestrial representatives. Isopod species lists were typically prepared according to different habitats, which was true also for Slovenia. Here, we prepared the first unified overview of isopod species for Slovenia, which is also the first list of marine isopods in the country. We examined scientific publications, research reports and institutional databases. A total of 126 species have been recorded in Slovenia, of which 31 are marine, 21 are found in freshwater, and 74 are terrestrial. Of these, we report on seven marine and one terrestrial species for the first time. A major part of freshwater isopod richness is linked to the subterranean environment, where most endemic species for the country can be found. Among marine species, many are parasites, with potential economic impact, and two species are considered introduced. When the new species list is considered with valid national legislation, only 41 species retained the same taxonomic status. Many synonyms and invalid taxa according to recent taxonomy point out the need for revision the national red list of Malacostraca as well as other nature protection acts.

390. A preliminary life history traits analysis of sharks in the Sea of Marmara (Türkiye), where deoxygenation and habitat deterioration are raising concernsHakan Kabasakal, Serdar Sakinan, Lovrenc Lipej, Danijel Ivajnšič, 2023, izvirni znanstveni članek Povzetek: Life history traits of 17 species of sharks occurring in the Sea of Marmara were analysed based on Gower’s distances, Principal Coordinate Analyses, and hierarchical clustering. The analysis shows that the sharks of the Sea of Marmara can ecologically be divided into several clusters. The increasing occurrence of sharks on the Marmara continental shelf, especially in the last few years, suggests that the expected habitat compression due to deoxygenation has begun to take place. This situation, which can be considered as a “habitat trap” for sharks, should be considered as a threat that may lead to shark mortalities due to the intensification of bycatches or even the intentional killing of sharks. Available results are sufficient to predict a disturbing future for sharks of the Sea of Marmara if the factors (deoxygenation, habitat loss, bycatch, etc.) threatening the overall ecosystem do not improve.
