Physical literacy (PL) is the foundation for lifelong participation in physical activity. Most previous research concentrated on PL examinations in younger groups, while such research is scarce in the adult population. This study aimed to determine the PL levels of the Croatian adult population. Also, the aim was to investigate whether individuals with longer participation in organized physical activity have higher PL levels and do males and females differ in PL levels. The sample comprised 561 individuals (321 females, 240 males) aged 27.65±12.13 years. PL levels were assessed by the Croatian version of the Perceived Physical Activity Questionnaire (PPLQ-Cro). Demographic characteristics included age, gender, and years of involvement in organized physical activity. Gender differences were calculated using the Mann-Whitney U test and effect sizes. Spearman correlation coefficients were used to determine associations between study variables. Males had significantly higher PL levels compared to females (83.10±16.17 for males and 74.27±20.07 for females, Z=-6.88, p=0.001). Years of organized physical activity were associated with PL levels (R=0.48, p=0.001) in the total sample as well in males (R=0.55, p<0.001) and females (R=0.24, p<0.01) separately. The finding that years of organized physical activity are associated with total PL supports the theory that PL is the cornerstone for participating in lifetime physical activity. The results of this study emphasize the importance of introducing the concept of PL in numerous institutions and organizations connected with organized physical activity.

Factors associated with doping in sports are frequently studied, but sport specific, gender-stratified investigations are rare. This study aimed to evaluate sociodemographic and sport factors associated with doping tendency (DT) in professional handball players. The participants were handball professionals from Croatia and Bosnia and Herzegovina (n=173; 22.12±3.11 years of age, 64 females and 109 males) who were tested on sociodemographic variables (gender, age, education), sport factors (experience in sport, achievement at the junior and senior level), and doping factors (personal opinion on the problem of doping, doping knowledge, and personal DT). Logistic regressions with sociodemographic- and sport-factors as predictors were calculated for binarized outcome (positive DT vs. negative DT). A greater likelihood of having a positive DT was found for males than for females (OR=1.60, 95% CI: 1.16-2.12) and for those who achieved success at the junior level (OR=1.21, 95% CI: 1.02- 1.95). Among females, positive DT increased with experience in handball (OR=1.31, 95% CI: 1.11-1.55). Male players who achieved better competitive/sport results at a younger age were more prone to doping (OR=1.50, 95% CI: 1.21-1.83). While a greater tendency toward doping in males might be expected due to sociocultural factors, the gender-specific associations indicated specific factors that must be noted in the development of anti-doping strategies in this sport.

Peripartum depression (PPD) has been the focus of many studies, clinical interventions and policymaking over the past decades, yet more work is needed in order to mitigate this disorder and its negative consequences. This symposium offers an examination, through various review techniques, of five emerging understudied topics related to PPD diagnosis, treatment and policy implications. Through a scoping review, the first presentation considers how economic evaluation can inform the development of mental health policy strategies and guidelines and identify implications for preventive, screening and treatment strategies for PPD. The second presentation increases understanding of PPD disorder diagnosis through a synthesis of current literature on issues regarding PPD diagnosis in different aspects. The third presentation focuses on Paternal PPD (P-PPD) and presents a consensus report on emerging issues and questions on the prevention, diagnosis and treatment of P-PPD The fourth presentation presents, through an umbrella review of systematic reviews and meta-analyses, an overarching synthesis of the literature regarding complementary and alternative therapies (CATs) to treat PPD, while assessing the extent to which CATs are associated with depressive symptoms reduction during pregnancy or after childbirth. The fifth presentation focuses, through a systematic review, on the effectiveness of Third Wave cognitive behavioral psychological interventions in treating peripartum depression. All five presenters will discuss the major findings of their work as well as potential implications for research, clinical practice and policy. Collectively, this set of papers advances the understanding of PPD diagnosis, prevention and treatment and of implications for clinical practice, research and policy.

Start of offense significantly affects the development and execution of the offense. Evaluation of beginnings of offense in professional European and American basketball reveals proportional distribution of 12 applied modalities, however, statistical analysis showed significant differences between the two basketball systems. NBA comparatively demonstrates a higher frequency of offenses that start by winning the ball without time stoppage. In contrast, Euroleague shows significantly greater representation of offensive beginnings by inbounding the ball. The most common forms of offensive openings in basketball are by Inbounding the ball from the baseline on back-court, followed by Opening of offense by a defensive rebound after an unsuccessful field-goal attempt. Both forms are slightly more pronounced in the US professional basketball. A higher degree of offensive efficiency was shown after steals, as it was expected, however, the execution of such modality has also a higher success rate in the NBA. The research results indicate the specific characteristics of observed basketball systems based on correlation of conversion type and situational outcomes. Those explicit features partially affect the principles of appropriate game and training concept.

This study investigated achievement goal orientation profile differences between youth swimmers on perceived competence and enjoyment, and the contribution of goal orientation and perceived competence to enjoyment in swimming. Male and female swimmers (n=302), aged 10-18 years (M=12.7; sd=2.25) completed a questionnaire assessing goal orientation, perceived competence and enjoyment in swimming. Cluster analysis revealed four goal orientation profile groups: high task/high ego, moderate task/low ego, high task/moderate ego and low task/moderate ego. MANOVA was conducted and a significant multivariate effect was found (Wilks=0.762; F=14.370; p=0.000; ES=0126). Further, Scheffe’s post-hoc comparisons tests revealed that swimmers scoring relatively high in both task and ego orientations, with a balance between the two, reported high values for perceived competence and enjoyment. Finally using two-way factorial MANOVA it was found that the interaction between the perceived competence and goal orientation profiles was not significant. Emphasizing task orientation for young athletes is a means to increase enjoyment in sport, regardless of their level of perceived competence.

U ovom radu istraživane su razlike antropoloskog statusa ucenika i ucenica petog i sestog razreda osnovne skole koja žive u urbanom podrucju (Mostar) u odnosu na ucenike i ucenice petog i sestog razreda osnovne skole koji žive u ruralnom podrucju (Biograci-Siroki Brijeg). Na uzorku 79 ispitanika, 19 ucenika i 19 ucenica iz Mostara, 22 ucenika i 19 ucenica iz Biograca primijenjeno je 9 testova za procjenu antropometrije, fleksibilnosti, brzine izvođenja naizmjenicnih pokreta, eksplozivne snage, repetitivne snage, jakosne izdržljivosti, koordinacije i aerobne izdržljivosti. Nezavisnim t – testom i diskriminacijskom analizom je utvrđeno postojanje statisticki znacajnih razlika između ucenika i ucenica iz Mostara i ucenika i ucenica iz Biograca. Ucenici i ucenice znacajno se razlikuju u eksplozivnoj snazi, repetitivnoj snazi, fleksibilnosti i aerobnoj izdržljivosti dok u ostalim varijablama nema statisticki znacajnih razlika.

The study examined the effects of a three-month long weight loss programme (consisting of aerobic and strength exercise and nutrition) on changes in body composition of twenty healthy middle age overweight women, aged 38 to 55 (average 45,8), who led sedentary lifestyle. Data was analysed with t-test (t-paired) in order to compare individual variables before and after the weight loss programme. Training consisted of 30 min of cycle ergometry at 60–70% maximal heart rate, 3 times weekly for 3 months, followed by strenght exercises for all muscle groups. The results showed the reduction of body mass (in average 8 kg - 0.6 kg per week) and fat percentage (more than 4%). Body mass index has decreased by nearly 3 units. Skin fold values have been reduced by approximately 20% with the most noticeable decrease of circumferences in the torso area (hips and waist). The programme should be continued until body mass index values drop below 30 and consequently body weight to normal value.

The objective of this study is to determine the impact of specifically programmed training during one year cycle on changes in some strength and power assessment tests in basketball players of junior and younger senior age. The sample of subjects included 17 basketball players of junior age HKK “Siroki” from Siroki Brijeg, Bosnia and Hercegovina, 16 to 18 years old. The battery of tests which monitored the progress in strength and power dimensions consisted of 8 items. Four items estimated maximum strength (barbell bench press, barbell shoulder press, squat, deadlift), three items for relative repetitive strength assessment (dips-chest version, pullups and 3/4 Sit-Ups) and one item for absolute explosive strength assessment (power clean). As a special variable we also recorded gain of body mass throughout annual training cycle. Planned and implemented macrocycle consisted of 376 days, 169 days of training, 169 training units, i.e. 211 hours of training total. The results obtained indicate significant effects of treatments in strength and power domain.

The creation of professional basketball players implies a continuous and progressive basketball education. The aim of this study is to determine relations in a cadet age basketball players between their basic motor skills and specific motor skills, that is, to determine relations between tests conducted in order to estimate the successfulness of the basketball game. The sample consisted of 54 basketball players of cadet age on whom was applied the set of 5 specific tests for the evaluation of the success in the game itself, and the set of predictability variables that consisted of 12 tests for the basic motor skills. There was shown a significant cohesion between the basic motor skills and the specific factors of the basketball game. The high percentage of explained variance speaks of good set selection of basic tests and its importance in the influence to evaluate the specific motor skill needed in the basketball game. The obtained results could be of great importance in order to select specific motor skill tests that could be conducted for the purpose of orientation and selection of young basketball players.
