Item type:Publication, BODY COMPOSITION RELATED TO BODY MASS INDEX AMONG YOUNG ELITE FOOTBALL PLAYERS(Medical faculty, Ss Cyril and Methodius University in Skopje, 2017); ; ; ; Abstract Introduction. Body composition is extremely important for athletes’ performance, thus assessment tools may be used to clarify their sports condition. The aim of the study was to investigate body composition measurements and maximal oxygen consumption related to body mass index (BMI) in young elite football players. Material and methods. A total of 29 young football players were divided into 3 groups related to the value of BMI: I group (n=8); II group (n=13); and III group (n=8). The subjects were submitted to the sub-maximal pulse approach on treadmill method (SchillerAg, MTM-1500 Bear, Switzerland) to measure VO 2max (ml/kg/min). A body composition analyzer (InBody720, Biospace Co, Seoul, Korea) was used to determine the body fat - BF (%), skeletal muscle - SM (%) and total body water – TW(L) including intracellular body water – ICW(L) and extracellular body water – ECW(L). For the statistical analysis, a t-test was performed upon which the significance for p<0.05 was considered. Results. The football players showed the highest VO 2 max value in the II group (p<0.05). BF showed increased value in the III group (p<0.02). SM did not show any significant difference between the groups. Body water composition showed no statistical significance. Conclusion. Due to our results, we may conclude that certain parameters may determine the condition of young athletes in order to select appropriate training procedures, proper diet, and personalized performance. Key words: football; body mass index; body composition. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, COMPARISONS AND CORRELATIONS OF THE ELECTROCARDIOGRAPHY CHANGES REGARDING THE FUNCTIONAL FEATURES BEFORE, DURING AND IMMEDIATELY AFTER THE TREADMILL TEST WITH ATHLETES(Faculty of Physical Education, Sport and Health in Skopje, 2019); ; ; ; The need for cardiovascular screening in order to timely detect and diagnose the morphological and functional changes of the heart, which occur as a result of doing sport actively, and thus to avoid the occurrence of sudden cardiac death, is generally accepted. To achieve the objectives of the study, two noninvasive diagnostic methods for cardiovascular evaluation were used: electrocardiography (ECG) and the Bruce protocol test. The purpose of this study was to determine and examine the relationship of ECG changes to functional characteristics before, during, and/or immediately after exercise testing. This crosssectional study conducted during 2016/2017 involved 285 athletes aged 9 to 38, of both sexes. They were all given a 12-channel electrocardiogram (ECG) at rest, after which personal, family and sports history and anamnesis were given, followed by a Bruce protocol test and functional parameters were examined (symptoms, metabolic equivalents, METs, test duration, exercise capacity-VO2 max, rhythm disturbance, heart rate, heart rate reserve and recovery, chronotropic incompetence (CI), systolic and diastolic blood pressure). According to ECG changes and in accordance with international recommendations for its interpretation, athletes were divided into 4 groups: with normal, physiological, borderline or abnormal ECG findings. The results showed a significant positive connection between abnormal ECG and the occurrence of rhythm disturbance during the exercise test (r = 0.119; p = 0.045); Cardiovascular capacity expressed in (METs) compared to respondents with normal ECG was significantly higher in those with physiological ECG changes (p = 0.003), HR reserve percentage was lowest among athletes with abnormal ECG, and CI had the highest percentage. It can be concluded that an athlete with borderline, abnormal, and possibly physiologically assessed ECG should undergo further evaluation. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, The changes of ACTH, cortisol, testosterone and testosterone/cortisol ratio in professional soccer players during a competition half-season(Comenius University, School of Medicine - AEPRESS SRO, 2006-02); ; ; Mickoska, EThe following up of some hormonal parameters during the professional soccer training process could be one of the indicators of the training effects. On the other hand, overreaching and overtraining as an opposite adaptation of supercompensation could be detected by following up some hormonal changes. The aim of this study is to evaluate the changes in some hormonal parameters in professional soccer players during a half-season competition. We included 30 professional soccer players from a soccer club of our National Soccer League in this study. All sport medical examinations were conducted tree times: before the preparation phase, before the competition phase (after previous phase) and after finishing the competition phase. There were significant differences in all evaluated hormones between three phases of soccer training process, including significant decrease in T/C of more than 30% at the end of the competition phase (phase III). The decrease in muscle mass after the preparation phase and the increase in fat mass at the end of competition phase were insignificant. The hormonal changes indicated that some indices could indicate overreaching and overtraining at the end of professional soccer competition season. Although insignificant, the decrease in muscle mass after the preparation phase and the increase in fat mass at the end of competition phase were undesirable effects for us (Tab. 4, Fig. 2, Ref. 19).
