-season (T1) to the mid-season (T2) to the end-of season (T3). Second, it was hypothesized that psychological strategies measured at the pre-season (T1) would predict athletes’ endurance performance and satisfaction with individual performance at the end-of-season (T3), after controlling for the respective baseline index of endurance performance or satisfaction with individual performance at T1.
At T1, the study sample consisted of 97 male soccerplayers aged 16–27 years (M = 18.23, SD = 1.84), with reported training experience of 3

endurance capacity when compared to the wild‐type gene variant ( Eynon et al., 2013 ). Vincent and colleagues (2007) established that in human muscle biopsy samples obtained from healthy, untrained young men, proportion of fast‐twitch fibers differed among 577RR and 577XX individuals, in favor of 577RR carriers. Genotype 577XX seems to be beneficial for endurance performance; this genotype occurs with higher frequency in endurance athletes than in sprinting/power athletes. In terms of soccerplayers, those harboring 577RR genotype have higher jumping potential and are

This study analyzed soccer players’ retention of coaches’ feedback during training sessions. We intended to determine if the retention of information was influenced by the athletes’ personal characteristic (age, gender and the sports level), the quantity of information included in coach’s feedback (the number of ideas and redundancy), athletes’ perception of the relevance of the feedback information and athletes’ motivation as well as the attention level. The study that was conducted over the course of 18 sessions of soccer practice, involved 12 coaches (8 males, 4 females) and 342 athletes (246 males, 96 females), aged between 10 and 18 years old. All coach and athlete interventions were transposed to a written protocol and submitted to content analysis. Descriptive statistics and multiple linear regression were calculated. The results showed that a substantial part of the information was not retained by the athletes; in 65.5% of cases, athletes experienced difficulty in completely reproducing the ideas of the coaches and, on average, the value of feedback retention was 57.0%. Six variables with a statistically significant value were found: gender, the athletes’ sports level, redundancy, the number of transmitted ideas, athletes’ perception of the relevance of the feedback information and the athletes’ motivation level.

Considering the limited knowledge regarding the effects of n-3 and n-6 PUFAs on the inflammatory response during physical activity, we aimed to evaluate the level of pro- and anti-inflammatory cytokines in young soccer players before and after a maximal physical load test at the beginning and end of a two-month training process. The study included 75 young footballers from Football School “Kragujevac,” who were followed during the two-month training programme. The subjects were divided into the following groups: 1) control group (consumed a standard diet); 2) group that consumed fish oil (2500 mg of n-3 PUFAs per day); 3) group that consumed nutritional sunflower oil (2500 mg of n-6 PUFAs daily). The maximal progressive exercise test was performed using a treadmill belt. Venous blood samples were drawn 4 times for the determination of cytokine levels (IL-6 and TNF-α): before and after the exercise load test before the two-month training programme (initial measurement) and immediately before and after the exercise load test after the two-month training programme (control measurement). Supplementation with fish oil (n-3) has been associated with reduced levels of IL-6 compared with the initial values. After an acute bout of exercise, n-3 PUFAs did not show a significant effect on inflammatory marker dynamics, whereas n-6 PUFAs slightly stimulated the production of TNF-α.
