Sex-specific relationship patterns between body morphology and maturity status with change of direction and agility in elite adolescent volleyball players.

This study explored sex-specific patterns in the relationship between maturity, body morphology, and change of direction (COD) and agility (AG) in adolescent volleyball players. The sample comprised 22 males and 24 females aged 15-17 with at least 4 years of sports experience. Measurements included body height, weight, muscle and fat mass, leg length, and center of mass.

Prognostic Power of Foot Mobility in Identifying the Risk of Musculoskeletal Injuries: A Cross-Sectional Study of Male Volleyball Players at Different Competitive Levels.

(1) Background: The arch structure and mobility of the foot are considered injury risk factors in volleyball. However, there are limited studies presenting differences in injury prevalence and the risk of lower limb injuries in relation to the competitive level in male volleyball. Therefore, the main aim of the current study was to evaluate foot mobility (through navicular drop test) as an injury risk factor in volleyball players from different competitive levels.

The Functional Form of the Relationship between Body Height, Body Mass Index and Change of Direction Speed, Agility in Elite Female Basketball and Handball Players.

The aim of this study was to assess the functional form of the relationship between two anthropometric measurements-body height (BH) and body mass index (BMI)-and two motor abilities-change of direction speed (CODS) and agility (AG)-in female elite basketball and handball players. It was hypothesized that BH and BMI might be significantly associated with AG and CODS. Two scenarios of the Five-Time Shuttle Run to Gates test (planned and unplanned) were used to evaluate the CODS and AG.

Acute Performance Enhancement Following Squats Combined With Elastic Bands on Short Sprint and Vertical Jump Height in Female Athletes.

Krčmár, M, Krčmárová, B, Bakaľár, I, and Šimonek, J. Acute performance enhancement after squats combined with elastic bands on short sprint and vertical jump height in female athletes. J Strength Cond Res 35(2): 318-324, 2021-The main purpose of this study was to compare back squats with and without elastic bands on sprint and vertical jump height.

Multiple athletic performances, maturation, and Functional Movement Screen total and individual scores across different age categories in young soccer players.

The purpose of this study was to evaluate differences in multiple athletic performances, and to examine associations between athletic performance and Functional Movement Screen (FMS) in young soccer players. Forty-one soccer players were tested on peak height velocity (PHV), 5-, 10-, and 30-m sprint times, 505 change of direction (505 COD), Y-reactive agility tests, countermovement jump (CMJ), and squat jump (SJ) height. Significant main effects (<0.

Perceived Autonomy Support and Motivation in Young People: A Comparative Investigation of Physical Education and Leisure-Time in Four Countries.

Physical education focuses on the development of sports skills as well as fitness for health. In Central European countries there has been a shift in these focuses since the fall of Communism to follow internationally-recognised health-related physical activity recommendations, similar to Western European countries. In this study we investigated the extent to which motivation from school physical education transfers to leisure-time physical activity providing autonomy support by three social agents: school (physical education teachers), family and peers.

Social normative perceptions of alcohol use and episodic heavy drinking among Central and Eastern European adolescents.

This study examined alcohol use and related social normative perceptions among a sample of 1,886 Central-Eastern European high school students. The youth represented in the study averaged 16.5 years of age and were from several localities in the countries of Hungary, Slovakia, Czech Republic, and Romania.

Cigarette smoking and indicators of psychosocial distress in Southeast Asian and Central-Eastern European adolescents.

The purpose of this study was to examine the association of cigarette smoking and 2 indicators of psychosocial distress (hopelessness and loneliness) among adolescents from 2 distinctly different regions of the world: Central-Eastern Europe (Hungary, Ukraine, Slovakia, Czech Republic, Romania, Poland) and Southeast Asia (Thailand, Taiwan, and the Philippines). Among Southeast Asian boys and girls, smokers had elevated hopelessness in comparison to nonsmokers but among Central-Eastern European students, this relationship was true only for girls and there was no relationship for boys. Across the country samples, there was only association of smoking with loneliness among Southeast Asian girls and Central-Eastern European girls.

Self-perception of body weight, weight management practices and goals, and other weight-related factors in central and eastern European adolescents.

Self-perception of body weight, management practices and goals, and other weight-related factors were assessed among a sample of 2,566 adolescents from 30 high schools in Hungary, Slovakia, Czech Republic, Romania, Ukraine, and Poland. Students who perceived themselves as much too fat were more likely than those with other weight perceptions to engage in weight management practices to lose weight, have higher body mass index, rate themselves lower on physical attractiveness, and estimate higher percentages of their same-sex friends as trying to lose weight. Similar to other research, boys and girls differed on self-perception of weight and other weight-related factors.

Friendships and physical activity: investigating the connection in Central-Eastern European adolescents.

Studies investigating physical activity among adolescents living in post-communistic Central-European countries are sparse, particularly in light of the fact that some research has identified that adults in these countries exercise less frequently than western counterparts. The purpose of this study was to investigate whether physical activity participation is associated with certain friendship factors, the ability to make friends, level of involvement with friends, and perceived friends' involvement in physical activity, among 1,886 Central-Eastern European high schools students. The results of this study corroborated previous research in other adolescent populations in which it has been found that overall participation in physical activity was lowest among adolescents who said that making friends was difficult, who were less involved with friends, and who reported that making friends was difficult.

Cigarette smoking, friendship factors, and social norm perceptions among central and Eastern European high school students.

Studies investigating smoking behavior among adolescents living in post-communistic Central-European countries are sparse. This study focused on the relationship between cigarette smoking, certain friendship factors, and social norm perceptions among 1,886 Central-Eastern European adolescents from high schools in Hungary, Slovakia, Czech Republic, and Romania. Smoking behavior was related to having friends who smoke, ease or difficulty making new friends, time spent with friends after school and during evenings, and estimations of the prevalence of smoking by schoolmates.
