The primary aim of this study was to determine reliability and factorial validity of squat (SJ) and countermovement jump (CMJ) tests. The secondary aim was to compare 3 popular methods for the estimation of vertical jumping height. Physical education students (n = 93) performed 7 explosive power tests: 5 different vertical jumps (Sargent jump, Abalakow's(More)
The purpose of this study was to evaluate the effects of sprint training on muscle function and dynamic athletic performance and to compare them with the training effects induced by standard plyometric training. Male physical education students were assigned randomly to 1 of 3 groups: sprint group (SG; n = 30), plyometric group (PG; n = 30), or control(More)
The purpose of this study was to evaluate the reliability and factorial validity of agility tests used in soccer. One hundred fifty (n = 150), elite, male, junior soccer players, members of the First Junior League Team, volunteered to participate in the study. The slalom test (ST) sprint 4 x 5 m (S4 x 5) and sprint 9-3-6-3-6-9 m with 180 degree turns (S180(More)
The purpose of this study was to evaluate whether players in different positional roles have a different physical and physiologic profile. For the purpose of this study, physiologic measurements were taken of 270 soccer players during the precompetitive period of 2005/06 and the precompetitive period of 2006/07. According to the positional roles, players(More)
The purpose of this study was to determine the impact of body weight on fitness tests among the personnel of the Croatian navy. Forty two naval personnel (age 27 +/- 4.1 years; body mass 86.2 +/- 4.9 kg; height 184.6 +/- 7.4 cm; body fat percentage 17.3 +/- 5.2) participated in this study. In order to evaluate the fitness of the naval servicemen, we applied(More)
OBJECTIVES In addition to being a serious health-hazard, substance-use-and-misuse (SUM) in military forces negatively influences physical fitness and army readiness. The aim of this study was to define the prevalence of SUM, which includes cigarette smoking, alcohol consumption, and multiple SUM (i.e. practice of daily smoking and harmful alcohol drinking),(More)
The purpose of this research was to identify the changes in tests assessing speed-explosiveness abilities after a completed proprioceptive training programme. The research included 75 physically active men divided into the experimental (n = 37) and the control (n = 38) group. The first group underwent the prop-rioceptive training programme lasting ten weeks(More)
Talent identification and development in soccer is often biased by maturation-related differences of young athletes. However, there is no information available about success rates for youth maturing at different tempos to achieve success in elite adult soccer. The purposes of this study were to determine the prevalence of different maturational groups among(More)
The purpose of this study was to determine the effects of agility training (training of acceleration, deceleration and quick change of the direction of movement) on athletic power performance. Eighty healthy male college students (age 19±1.1 years; body mass 77.2±7.1 kg; body height 180.1±7.1 cm; body fat percentage 10.8±1.6) participated in this study. The(More)
The purpose of this study was to investigate the effect of cigarette smoking history on physical fitness in younger adults. Small, insignificant differences in BMI between non-smokers and smokers were shown regardless of cigarette smoking history duration. Although the differences in muscular endurance increased in the samples with progressing cigarette(More)
