Hypovitaminosis D in Young Basketball Players: Association with Jumping and Hopping Performance Considering Gender

2021

This study aimed to verify whether a group of young well-trained basketball players presented deficiencies in vitamin D concentration, and to analyze whether there was an association between vitamin D concentration and jumping and hopping performance. Gender differences were considered. Twenty-seven players from an international high-level basketball club (14 female, 16.00 ± 0.55 years

Reliability of measurements during countermovement jump assessments: Analysis of performance across subphases

2020

The aim of this study was to examine the reliability of performance measures in the different phases and sub-phases of the countermovement jump (CMJ). Seventeen male athletes competing at a regional level completed 204 valid trails consisting of the execution of maximal hands-on-waist CMJs performed on a force platform. The vertical ground reaction force (VGRF) data obtained at a sampling frequency of 1000 Hz were used to calculate performance-derived variables and determine key points and jump sub-phases. The relative reliability of 92 variables was assessed using the intraclass correlation coefficient (ICC) from a two-way mixed effects model analyzing the time, force, power, velocity, and…

Translation and validation of Brunel Mood Scale for Serbian athlete population

2014

Ivica Rajkovic, 2014. Translation and validation of Brunel Mood Scale for Serbian athlete population. Master Thesis in Sport and Exercise Psychology. Department of Sport Sciences, University of Jyväskylä. 40p. Present study developed and validated the Serbian version (SERMS) of Brunel Mood Scale (BRUMS). BRUMS is 24 item questionnaire used to asses mood profile on six subscales (anger, confusion, depression, fatigue, tension and vigour). BRUMS was translated in to the Serbian using translation-back translation method, and administered to 354 athletes in Serbia and Montenegro. Exploratory factor analysis (EFA) and Cronbach’s alpha were used to determine factor validity and internal consisten…

Gender-Typed Sport Practice, Physical Self-Perceptions, and Performance-Related Emotions in Adolescent Girls

2020

Youth sport experience provides opportunities for physical, personal, and social development in youngsters. Sport is a social system in which socially constructed gender differences and stereotypes are incorporated, and specific sport activities are often perceived as gender characterized. The objective of this study was to examine the relationship between some salient physical and emotional self-perceptions and the type of sport practiced. A sample of 261 female athletes, aged 14–21 years (Mage = 15.59, SD = 2.00), practicing different sports, categorized as feminine (e.g., artistic and rhythmic gymnastics), masculine (e.g., soccer and rugby), or neutral (e.g., track and field and tennis),…

Referee Bias in Professional Football: Favoritism Toward Successful Teams in Potential Penalty Situations

2020

Past studies have indicated that multiple factors may influence sport referees' decisions, such as pressure from spectators and athletes' reputation. Grounded in the social impact theory framework, this study examined whether Norwegian Premier League (NPL) referees are biased by a team's success when awarding penalties. Using video footage (similar to video assistant referees), an expert panel (EP) of four NPL referees evaluated all potential penalty situations (N = 43) involving either of two successful teams during an entire NPL season. Fifty-five potential penalty situations from matches without successful teams were also rated. Overall, the match referees identified 73.3% (22 of 30) of …

Muscular Strength Imbalances Are not Associated with Skin Temperature Asymmetries in Soccer Players

2020

Although strength imbalances using isokinetic dynamometer have been examined for injury risk screening in soccer players, it is very expensive and time-consuming, making the evaluation of new methods appealing. The aim of the study was to analyze the agreement between muscular strength imbalances and skin temperature bilateral asymmetries as well as skin temperature differences in the hamstrings and quadriceps. The skin temperature of the anterior and posterior thigh of 59 healthy male soccer athletes was assessed at baseline using infrared thermography for the identification of hamstrings-quadriceps skin temperature differences and thermal asymmetries (&gt

Effects of Functional Strength Training on Functional Movement and Balance in Middle-Aged Adults

2021

Functional movement deficiencies cause falls and injuries in adults. Functional strength training (FST) is emerging as a new training method for athletes, middle-aged and older adults, to improve functional movement: The present study was conducted in order to investigate the effects of FST on balance and functional movement in healthy and independent middle-aged adults. The sample for this study consisted of 46 physically active individuals (24 female and 22 male). A total of 46 subjects were divided based on randomly into the functional strength training (FST) group (n = 26) aged: 51.55 ± 3.73 years; height: 168.69 ± 8.8 cm; body mass: 75.88 ± 12.18; and traditional s…

A person-oriented approach to sport and school burnout in adolescent student-athletes: The role of individual and parental expectations

2017

Abstract Objectives The present study aimed to examine what kind of burnout profiles exist among student-athletes based on their sport and school burnout symptoms. Moreover, it was investigated whether athletes' expectations of success in sport and school, on the one hand, and parental expectations, on the other hand, were predictors of the likelihood of the athlete to show a certain profile, after taking into account the effects of gender, grade point average, type of sport, and level of competition. Design and methods The participants were 391 student-athletes (51% females) from six different upper secondary sport schools in Finland, and 448 parents (58% mothers). The athletes filled in q…

Predicting moral attitudes and antisocial behavior in young team sport athletes. A self-determination theory perspective

2019

Identifying the factors associated with prosocial and antisocial behaviors in youth sport may provide evidence to inform interventions aimed at promoting prosocial behaviors and minimizing rule transgressions in young athletes. We investigated relations among social‐contextual factors (e.g., social support), personal motivational factors (e.g., psychological need satisfaction and motivation), young athletes’ attitudes toward prosocial (e.g., keeping winning in proportion) and antisocial (e.g., acceptance of cheating and gamesmanship) behaviors, and their actual rule violations during matches in two samples of athletes. Participants in Sample 1 were young team sport athletes (N = 355) and pa…
