Methods: A experimental study involved the participation of 207 soccer coaches (B, A and PRO UEFA coaching license). The subscale of the questionnaire refers to coaching and leadership competencies, contains 47 items and was created from the existing questionnaires. Responses to the items of the third subscale are also given in the form of a five-point Likert scale, where respondents were required to indicate the level of agreement with the given statements. The questionnaire examines coaching and leadership competencies contained in 6 groups of competencies. Each competency (communication competencies, football and other competencies, organizational competencies, leadership competencies, technical and motivational competencies, training technology competencies - performance monitoring and training/match analysis) consists of 7 or 8 items. The validation of the developed instrument in this empirical study was conducted using two procedures: (1) factor analysis (PCA with oblique rotation) and (2) an internal consistency assessment (Scale Reliability Analysis – Cronbach's Alpha). Results: By applying principal component factor analysis to the data of the "coaching and leadership competencies" subscale with oblimin factor rotation, 7 significant factors with a Kaiser value greater than 1 and 64.671% of the total variance were identified. Conclusions: The non-objectivity of the respondents was established by applying a self-evaluation scale, and it was confirmed that such questionnaires cannot be used to assess the accuracy of an individual's assessment. It is noticeable that the general opinion of coaches about the importance of certain competencies is probably wrong.

Soccer coaches, although not prominently featured in the foreground, are essential to the outcomes of the sport. They are key figures between athletes and organizational goals. Choosing, retaining, and developing the greatest athletes is the cornerstone to a successful coaching career. The aim of this study was to develop and validate a questionnaire that was determine the characteristic soccer coaching styles. A experimental study involved the participation of 207 soccer coaches (B, A and PRO UEFA coaching license). The questionnaire comprises 14 themes and consists of 65 items designed to evaluate soccer coaching styles, developed from the updated Leadership Scale for Sport. The validation of the developed instrument in this empirical study was conducted using two procedures: (1) factor analysis (PCA with oblique rotation) and (2) an internal consistency assessment (Scale Reliability Analysis – Cronbach's Alpha). Nineteen significant factors were extracted, and they are as follows: Player contribution to the game system; Cooperation/ Opinions; Implementation of coach's requirements; Teaching; Motivation; Conflict resolution; Informations; Sanction; Expressing an opinion; Error correction at own discretion; Highlighting the good and bad sides of players; Instructions; Team goal setting; Highlighting positivism/ negativism; The coach's personal expectations; Team solutions; Strategy creation; Social support; The influence of the team on coaching decision-making. By analyzing the data, it was determined that “B” football coaches are characterized by the coaching style "positive feedback", “A” soccer coaches by the "training and instructor" and "positive feedback" styles, while “PRO” coaches are characterized by the "positive feedback" style and a slightly lower frequency by the "training and instructor" style. Using only one coaching/leadership style is certainly a limiting factor, as different situations require different coaching approaches.

Original scientific paper Purpose of the research was to compare the effects of dynamic and proprioceptive neuromuscular facilitation (PNF) stretching on knee isokinetic strength and power parameters. Sample size of 50 male athletes is represented as male athletes divided into sub-samples of 10 athletes at competitive level in karate (19 ± 2,4), taekwondo (20 ± 3,6), boxing (19,8 ± 4,3), football (15,1 ± 0,3) and track and field sprint (18,3 ± 2,6). Isokinetic parameters of the knee were measured using Biodex isokinetic system3, at two angular speeds 60 °/s and 180 °/s. Parameters were measured after dynamic stretching protocol and again 48 h later after PNF protocol. For karate and taekwondo fighters no statistically significant differences were found. For boxers, football players and sprinters the values of strength and power parameters were higher after dynamic warm-up protocol at a statistically significant level. Results of this study confirmed that dynamic stretching contributes to higher values of the strength and power of thigh muscles compared to proprioceptive neuromuscular facilitation.
