The Importance of Reactive Agility Tests in Differentiating Adolescent Soccer Players.

The ability to differentiate the elite from nonelite athletes is not clearly defined. We investigated level differences in speed, change of direction speed (CODS), and reactive agility in a group of trained adolescent soccer players. A total of 75 adolescent male soccer players (aged 14-19 years) were recruited.

Effects of Small-Sided Recreational Volleyball on Health Markers and Physical Fitness in Middle-Aged Men.

The present study aimed to investigate whether recreational volleyball organized as small-sided games could improve fitness and health profiles of middle-aged men after 10 weeks of training. Twenty-four healthy men aged 35-55 were randomized in a small-sided recreational volleyball group (RV = 12; age: 44.7 ± 6.

The associations between sleep duration and sleep quality with self-rated health in young adults: a population-based study.

Background: The main purpose of the present study was to explore significant associations between sleep duration and sleep quality with poor self-rated health.

Methods: Subjects were 2100 university students (49.6% of women), aged 18-24 years.

Associations between sleep quality and its domains and insufficient physical activity in a large sample of Croatian young adults: a cross-sectional study.

Objectives: The main purpose of the present study was to explore the associations between sleep quality and insufficient physical activity.

Design: Cross-sectional.

Setting: Faculties in Croatia.

Are lower levels of physical activity and self-rated fitness associated with higher levels of psychological distress in Croatian young adults? A cross-sectional study.

Background: Although previous evidence has shown that physical activity and physical fitness lower the level of psychological distress, little is known of simultaneous associations between of physical activity and physical fitness and with psychological distress, especially in young adults. Therefore, the main purpose of the present study was to explore both separate and simultaneous association between physical activity and physical fitness with psychological distress.

Methods: Participants in this cross-sectional study were 2,100 university students (1,041 men and 1,059 women) chosen from eight faculties in the city of Zagreb.

The Associations between Sleep Duration and Sleep Quality with Body-Mass Index in a Large Sample of Young Adults.

Background: The main aims of this study were to explore the associations between time spent in bed (as a proxy of sleep duration) and sleep quality with overweight/obesity status in a large sample of young adults.

Methods: In this cross-sectional study, participants were 2100 university students (49.6% of women).

The effects of basic fitness parameters on the implementation of specific military activities.

The aim of this study was to determine whether basic fitness parameters have the impact on the specific military activity such as walking 18 km with 25 kg of load. The members of Croatian Armed Forces (30 soldiers) were tested before the beginning of the training program. The study has included variables for the assessment of muscular endurance: push-ups in 2 minutes, sit-ups in 2 minutes, maximum number of pull-ups before dropping from the bar, bench press with 70% of body weight-max number of repetitions, max number of squats for 60 seconds, then the variables for the assessment of aerobic capacity: the 3200m run and relative oxygen uptake using the direct method of measurement on a treadmill as well as the variable for the assessment of body fat (body fat %).

Effects of two different 5 weeks training programs on the physical fitness of military recruits.

The purpose of this study was to compare the effects of programmed continuous endurance and relative strength training (CERS) with the basic military physical readiness training (BMPR) on the physical readiness. Croatian military recruits (21.3 ± 1.
