Physical performance associated with mental toughness in elite soccer players
Although mental toughness (MT) is considered a crucial psychological component of sports performance, little evidence has been provided so far regarding the associations between MT and sport-specific performance in laboratory and on-field conditions. The main purpose of the study was to investigate the associations between MT and physical performance. In this observational study, 76 professional U21 male soccer players from six clubs were recruit…

The Three-Level Model of Factors Contributing to High-Intensity Intermittent Performance in Male Soccer Players
High-intensity intermittent performance in soccer is widely assessed using the yo-yo intermittent recovery level 2 test (YYIR2). This test is usually associated with aerobic-anaerobic performance. However, less is known about the direct or indirect contributions of abilities, including the anaerobic component. This study aims to propose a three-level model of factors contributing to YYIR2 performance, based on the investigation of relationships w…
Tracking of Maternal Physical Activity and Sport Participation over 11 Years
Purpose : Tracking of physical activity (PA) and sport participation (SP) during motherhood is poorly understood. The purpose of the study was to analyze the extent of tracking of maternal PA and SP. Methods : In this investigation, data were collected from the Czech ELSPAC study subsample of 4811 and 2609 women measured postnatally (1991-1992) and after 11 years of follow-up (2002-2003), respectively. The structured questionnaire was used to ass…
Tracking of anthropometric characteristics from childhood to adolescence
Findings show moderate to strong tracking of anthropometric characteristics, i.e. circumferences track moderately well, while strong tracking for indices and skinfold thicknesses is observed. Moreover, strong tracking of general overweight/obesity and abdominal obesity between ages 8 y and 15 y indicates that the detection of these risk factors at the beginning of primary school should be advocated
The Importance of Cardiorespiratory vs. Muscular Fitness in Reducing the Odds of Hypertension in War Veterans
Both CRF and MF are associated with the prevalence of hypertension, while the magnitude of the associations between MF and hypertension was more pronounced
Reference Data for Fat Mass and Fat-Free Mass Measured by Bioelectrical Impedance in Croatian Youth
Fat mass and fat-free mass have become useful clinical indices in determining healthy growth and physical development during critical periods of childhood and adolescence; however, despite a wide range of nutritional surveillance its study is limited by a lack of reference data. The purpose of this study was to establish sex-specific and age-specific standards for fat mass and fat-free mass in a large sample of Croatian children and adolescents. …

Their systolic and diastolic blood pressures were measured three times. The p…
Functional endurance capacity is associated with multiple other physical fitness components in 7–14-year-olds
Although significant, functional endurance capacity is weakly to moderately associated with other physical fitness components, pointing out that such measure should be tested separately from other aspects of physical fitness in school-aged children
More Time Spent in Sedentary Behaviors is Associated with Higher Plantar Pressures in Older Women
Background: Although obesity has been consistently correlated with higher plantar pressure during the lifespan, to date little evidence has been provided regarding of how domain-specific and total sedentary behaviors may be correlated with plantar pressures. Moreover, high peak plantar pressures have been consistently associated with foot pain and discomfort, which prevent individuals from being physically active. Therefore, the main purpose of t…
Domain-Specific and Total Sedentary Behavior Associated with Gait Velocity in Older Adults
Although it has been well-documented that older adults spend a significant amount of time being sedentary and have slower gait velocity, little is known of how physical fitness mediates the association between them. The main purpose of this study was to explore whether objectively measured physical fitness mediates the association between domain-specific and total sedentary behavior and gait velocity. We recruited 120 older adults aged ≥ 60 years…
Effects of Carrying Police Equipment on Spatiotemporal and Kinetic Gait Parameters in First Year Police Officers
The main purpose of the study was to explore the effects of carrying police equipment on spatiotemporal and kinetic gait parameters. Two-hundred and seventy-five healthy men and women attending police academy (32% women) were randomly recruited. Gait analysis without and with a police equipment load (≈3.5 kg) was analyzed using the Zebris pressure platform. Differences and effect sizes were calculated using a Student t -test and Wilcoxon test for…
Anthropometric Indices and Some Aspects of Physical Fitness in Croatian Adolescents by Gender
Background . The main purpose of this study was to explore the body-mass index and waist circumference associated with physical fitness by gender. Methods. In this cross-sectional study, we included 1036 adolescents (55.4% girls) from eight randomly selected secondary schools within the city of Zagreb (Croatia). Body-mass index and waist circumference were objectively measured. Physical fitness included three tests: (1) 1 min sit-ups, (2) standin…
Are Sedentary Behaviors Associated with Sleep Duration? A Cross-Sectional Case from Croatia
Although both sedentary behavior and sleep duration are risk factors for obesity, little evidence is provided regarding their mutual associations in young adults, who are at extreme risk of spending more time sitting and having irregular sleeping hygiene. Thus, the main purpose of the present study was to explore the associations between different sedentary behaviors and sleep duration. In this cross-sectional study, we recruited 2100 university …

How different contexts of social capital are associated with self-rated health among Lithuanian high-school students
BACKGROUND: Adolescents' self-rated health is related to a number of sociodemographic and socio-economic factors, health-related behaviors, and their social environment. The impact of the latter is still not well explored. An adolescent's social environment is represented by the social capital, i.e. social resources that they can access. The relationships between various contexts of social capital (family, neighborhood, peers, and school) and sel…
The Associations between Sleep Duration and Sleep Quality with Body-Mass Index in a Large Sample of Young Adults
Our results show that both short and long time spent in bed and poor sleep quality are associated with overweight/obesity status in young adults. Special interventions and policies that use both sleep duration and sleep quality as protective factors against overweight/obesity are warranted
