The purpose of this study was to examine the effects of medicine ball training on the strength and power in young female handball athletes. Twenty-one young female handball players (age, 16.9 ± 1.2 years) were randomly assigned to experimental and control groups. Experimental group (n = 11) participated in a 12-week medicine ball training program incorporated into the regular training session, whereas controls (n = 10) participated only in the regular training. Performance in the medicine ball throws in standing and sitting positions, 1 repetition maximum (1RM) bench and shoulder press, and power test at 2 different loads (30 and 50% of 1RM) on bench and shoulder press were assessed at pre- and posttraining testing. The athletes participating in the medicine ball training program made significantly greater gains in all medicine ball throw tests compared with the controls (p < 0.01). Also, the experimental group made significantly greater gains in bench and shoulder press power than control group (p < 0.05). Both training groups (E) and (C) significantly (p < 0.05) increased 1RM bench and shoulder strength, with no differences observed between the groups. Additionally, medicine ball throw tests showed stronger correlation with power tests, than with 1RM tests. These data suggest that 12-week medicine ball training, when incorporated into a regular training session, can provide greater sport-specific training improvements in the upper body for young female handball players.

The purpose of this study was to investigate the influence of additional resistance training on cardiorespiratory endurance in young (15.8 ± 0.8 yrs) male basketball players. Experimental group subjects (n=23) trained twice per week for 12 weeks using a variety of general free-weight and machine exercises designed for strength acquisition, beside ongoing regular basketball training program. Control group subject (n=23) participated only in basketball training program. Oxygen uptake (VO(2max)) and related gas exchange measures were determined continuously during maximal exercise test using an automated cardiopulmonary exercise system. Muscle power of the extensors and flexors was measured by a specific computerized tensiometer. Results from the experimental group (VO(2max) 51.6 ± 5.7 ml.min(-1).kg(-1) pre vs. 50.9 ± 5.4 ml.min(-1).kg(-1) post resistance training) showed no change (p>0.05) in cardiorespiratory endurance, while muscle strength and power of main muscle groups increased significantly. These data demonstrate no negative cardiorespiratory performance effects on adding resistance training to ongoing regular training program in young athletes.

SUMMARYAnti-doping programs need to preserve and promote what is essential in sport and that is sport spirit and achieving perfection through the development of its own natural talents, in order to raise awareness about the importance of fair play and creating an environment that supports the sport without doping. These programs should be directed to the athletes and young people by creating a positive and longterm impact on the choices they make. Thanks to games that are used for children in preschool and primary school age it is possible to efficiently and timely impact on the development character and virtues because it is incomparably more difficult to form character and moral values in already formed athletes than in childrens who are just getting to know the world of sport and everything what he is carries. Childrens need to be instilled the importance of physical exercise and the importance of participation in sport without prohibited resources and methods that roughly violate the ideal of fair play and on that way promote at childrens health, fairness and equality for all athletes. Fair play was created out of chivalry and gentlemanly in the middle ages where many reformers proposed sport and games with the aim of education and strengthening moral values in children. Teaching children the ideals of fair play in which the sport is based, and their continued involvement in sports activities with special accent on the pedagogical aspect leads to raising the awareness of moral values and ideals of sports chivalry. Developing awareness among children about fair play and anti-doping implies greater satisfaction with the results achieved in sports activities, which is a win at all costs and with the use of illegal resourses worthless, and victors would not be able to refer to with pride.

Cilj ovog rada je da da se ustanovi koji sportovi su najpopularniji kod učenika osnovnih škola na teritoriji Beograda, kako bi se ustanovilo koje bi sportove bilo poželjno uvesti kao izborni čas u nastavi fizičkog vaspitanja. Uzorkom je bilo obuhvaćeno 3 090 učenika. Najpopularniji sportovi su bili košarka, plivanje, odbojka a najmanje popularni akrobatika, orijentiring, ritmička gimnastika. Pokazalo se da postoji statistički značajna razlika u odnosu na pol (dječaci su u većoj mjeri priželjkivali uvođenje košarke i fudbala a djevojčice odbojke i plivanja), opšti uspjeh (đaci sa odličnim uspjehom su najčešće predlagali plivanje i odbojku, a učenici koji su imali vrlo dobar, dobar i dovoljan uspjeh su preferirali košarku) i bavljenje sportom (učenici koji se aktivno bave sportom kao i oni koji se više ne bave su preferirali košarku i plivanje a oni učenici koji se nikada nisu bavili sportom su preferirali odbojku i košarku).

The aim of the research was to examine and compare the effects of physical education (PE) classes with additional swimming training in relation to the regular teaching of PE on the motor abilities of students of a younger school age. A sample of 100 respondents was divided into two sub-samples in relation to the number of weekly exercises: a sub-sample of 50 students (control group-CG) with regular PE and a sub-sample of 50 students (experimental group-EG) who, besides their regular classes, had two additional weekly exercises in the form of swimming training. The training program of swimming courses was conducted for three months in the first semester of the 2015/2016 school year. Five standardized Eurofit battery tests were used to evaluate their motor abilities. The obtained results indicate that two additional weekly exercises in the form of swimming training caused statistically significant differences between the EG and the CG in long distance jogging, sit-ups for 30 s and a 20 m run test with a progressive increase in speed. The results suggest that swimming in addition to the already known impact on physiological characteristics positively influences the transformation of motor abilities in students of a younger school age.
