The aim of the study was to analyze differences in power performance and morphological characteristics of young Croatian soccer players with respect to their team positions and to establish correlations between the power performance variables. Anthropometric characteristics and jumping and sprint performances were analyzed for 45 soccer players (age 14-15; mean body height 175.4 +/- 6.61 cm; bo...

Freshmen college soccer players will have lower training ages than their experienced teammates (sophomores, juniors, seniors). How this is reflected in field test performance is not known. Freshmen (n = 7) and experienced (n = 10) male field soccer players from the same Division I school completed soccer-specific tests to identify potential differences in incoming freshmen. Testing included: ve...

Match-lay demands of Gaelic football and fitness profiles were assessed at club competitive level. English Gaelic football club championship players (n = 11) were assessed for anthropometry, leg strength and time to exhaustion on a treadmill run. A similar test battery was administered to a reference group of University competitive soccer players (n = 12). Heart rate was recorded during match-p...

In the recent years, there has been remarkable development in the scope and quality of soccer physiology and medicine. However, there is a shortage of descriptive data concerning the physical and physiological characteristics of soccer players from Eastern Europe while much more literature exists providing information on male Western European and American soccer (Rhodes et al., 1986; Davies et ...

The purpose of this study was to examine the effects of acute creatine-monohydrate supplementation on soccer-specific performance in young soccer players. Twenty young male soccer players (16.6 +/- 1.9 years) participated in the study and were matched and allocated to 2 randomly assigned trials: ingesting creatine-monohydrate supplement (3 x 10-g doses) or placebo for 7 days. Before and after t...

The aim of this study was to examine the decision-making performance of experienced and inexperienced soccer players at four exercise intensities (rest, 40%, 60%, and 80% maximal aerobic power). The decision-making performance of inexperienced players was expected to demonstrate an inverted-U shape with increasing levels of exercise. For the experienced players, decision making was predicted to...

OBJECTIVE To examine the changes in aerobic endurance performance of professional youth soccer players throughout the soccer season. METHODS Nine youth soccer players were tested at six different time points throughout the soccer season by sub-maximal blood lactate assessment, using an incremental treadmill protocol. Whole blood lactate concentration and heart frequency (Hf) were determined a...

BACKGROUND Data concerning the physical demands of soccer (e.g., activity pattern) suggest that a high level of performance requires well-developed neuromuscular function (NF). Proficient NF may be relevant to maintain and/or increase players' short- (intense periods of soccer-specific activity; accelerations, decelerations, and sprinting) and long-term performance during a match and throughout...

conclusions the modified illinois change of direction test must be considered as an asymmetrical test because it underestimates more than half of the players’ agility performances. therefore, fitness coaches should take these results into account when using this test. results the analysis revealed no significant difference in time performance between the two versions of test as a within-subject...

Whereas nutrition has a crucial role on sport performance, it is not clear to what extent nutrition knowledge is associated with physical fitness. The aim of this study was to examine the current level of nutrition knowledge of soccer players and whether this level is associated with physical fitness. Soccer players (n = 185, aged 21.3 ± 4.9 yr, weight 72.3 ± 8.4 kg, and height 177.5 ± 6.4 cm) ...
