Na uzorku od 45 ispitanika, muškog pola, 15 fudbalera FK „Čukarički Stankom“ iz Beograda, 15 kajakaša KK „Ivo Lola Ribar“ iz Beograda i 15 džudista JK „Olimp“ iz Beograda, uzrasta od 19 do 25 godina, bilo je izvršeno merenje maksimalne potrošnje kiseonika i srčane frekvence u opterećenju direktnom metodom - Conconijevim testom na pokretnoj traci. Primenom univarijatne analize varijanse, utvrđeno je da postoji statistički značajna razlika između navedenih grupa sportista u varijabli VO2 max. Primenom t-testa za dve nezavisne grupe utvrđeno je da postoji statistički značajna razlika između kajakša i fudbalera u varijabli VO2 max u korist kajakaša, između fudbalera i džudista u korist fudbalera i kajakaša i džudista u korist kajakaša. U varijabli Srčana frekvenca u opterećenju, statistički značajane razlike nisu uočene.

Background and Study Aim. Team sports, basketball and handball, as well as their competitions, are very popular throughout the world. The aim of this research was evaluation and comparative analysis of the results of a vertical jump between young basketball and handball players. Material and Methods. A  group  of  37  participants  took  part  in  the  research: 21 basketball players from the basketball club OKK ''Novi Pazar'' (age: 15.5 ± 0.5) from Novi Pazar formed the first subgroup and 16 handball players from the handball club RK ''Železničar 1949'' (age: 25.4 ± 5.8; body height = 193.5 ± 7.5 cm; body weight = 94.0 ± 7.4 kg; body mass index = 25.03 ± 2.38 kg/m2) from Niš formed the second subgroup. Explosive power of the vertical jumps was assessed by the following tests: countermovement jump, countermovement jump/arm swing, squat jump. Participants had at least 5 years of  training experience and held similar acute training histories prior to study commencement, completing 4 weeks of baseline conditioning during the general preparatory phase. Participants were free of injury, illness and disease as determined by a team physician prior to study participation. Results. The results of the independent samples t-test show that there were no significant differences (p > 0.05) between basketball and handball players in all vertical jump tests. Conclusions. This article contains new information about vertical jumps of young male basketball and elite male handball players that could be extremely useful for coaches. Also, these findings suggest that basketball coaches may benefit from talents’ identification in young basketball players.

Body mass index (BMI) and body image (BI) are constructs worth examining in the context of physical activity (PA), and they are both related to quality of life (QoL). PA, BMI, and BI should all be considered as associated parameters, and their effect on QoL should be examined and understood. This study aimed to determine the moderating role of PA in the relationship of BMI and BI with QoL. The sample of examinees consisted of 500 respondents (307 women; aged 39 ± 6 years). A physical activity self-evaluation questionnaire (IPAQ-SF) was used to estimate PA; BI was evaluated by using the Body Image Dimensional Assessment (BIDA) questionnaire, while QoL was determined with the WHOQOL-BREF questionnaire. The results showed that vigorous PA moderates the relationship between BMI and social relationships in adults (Sig. = 0.000). Walking and vigorous PA affect the relationship between BMI and environmental health (Sig. = 0.017 and Sig. = 0.049, respectively). Both walking (Sig. = 0.035) and moderate PA (Sig. = 0.032) alternate the relationships between BI and social relationships. Walking (Sig. = 0.000) and vigorous PA (Sig. = 0.016) moderate the relationship between BI and environmental health. The influence of PA on the moderation of the relationship of BMI and BI with physical and psychological health in the working population was not statistically significant.

Sports are the physical activities that named according to their respective ways of playing. There is a misleading concept regarding sports that only players can participate in physical or sports activities. But the true is that as the science and technology has made individual to rely on machines, its becomes necessary for all to take part in any kind of physical and sports activities to escape one from the hypo kinetic disorders and to keep physical fitness and wellness. This study has analyzed the role of sports in relation to maintain and promote physical fitness and wellness.
