- СтавкаEffect of hyperbaric chamber on saturation and heart frequency(Romanian Association of Balneology, Editura Balneara , Romania, 2023) Bjelica, Bojan; Zelenović, Milan; Alexe, Cristina Ioana; Aksović, Nikola; Setiawan, Edi; Pržulj, Radomir; Pan-telić, Saša; Bubanj, Saša; Kulundžić, Dejan; Lungu, Ecaterina; Catalin Ciocan, Vasile; Alexe, Dan IulianIntroduction: (1) Background: The use of oxygen under pressure greater than atmospheric represents progress that can be measured in terms of importance with the introduction of blood transfusion and antibiotics in therapy. The aim of the research was to determine the impact of using a hyperbaric chamber (HC) on muscle, arterial saturation and heart rate.; (2) Methods: Twelve respondents who engaged in recreational exercise. HC Macy Pan O2 801 was used for oxygen delivery. Muscle saturation was assessed with the IDIAG Moxy device. Arterial saturation was monitored with an Omron OM-35 device, and intraventricular heart rate with a Polar FT2 device. All parameters were monitored before and after HC treatment for 50 min. and constant pressure of 2.5 ATA.; (3) Results: There was a significant increase in saturation in the pectoralis, (+8.99%) p=.038, hamstring (+8.62%) p=.042. In capillary saturation (+1.42%) p=.008. Heart rate was reduced on average by about 8.5 beats p= .003. In the region of the latissimus do not record a statistically significant change in oxygen (+6.64%) p=060, however, numerical differences were determined.; (4) Conclusions: HC is an effective means of achieving positive physiological effects. It needs to be determined whether a higher ATA or duration of treatment gives better effects.
- СтавкаEvaluation and comparative analysis of the results of a vertical jump between young basketball and handball players(IP lermakov S.S., 2022) Aksović, Nikola; Bjelica, Bojan; Milanović, Filip; Cicović, Borislav; Bubanj, Saša; Nikolić, Dejan; Skrypchenko, Iryna; Rozhechenko, Victor; Zelenović, MilanBackground 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.
- СтавкаLeisure-Time Physical Activity and All-Cause Mortality : A Systematic Review(Jyväskylän yliopisto, University of Jyväskylä, Finland, 2022) Zelenović, Milan; Kontro, Titta; Dumitru, Razvan Constantin; Aksović, Nikola; Bjelica, Bojan; Alexe, Dan Iulian; Corneliu, Dragoi CristianMany scientific studies have been shown the positive effect of physical activity (PA) on reducing morbidity and mortality, whereas physical inactivity is globally one of the leading factors in mortality. Therefore, the purpose was to investigate the relationship between leisure-time physical activity (LTPA) and all-cause mortality among adult population. The data search was performed of 3 electronic databases for the years 2000-2021 February as follows: Google Scholar, PubMed, and ResearchGate. This search was made by using the following terms and operators AND/OR, individually/combination: "physical activity", "physical fitness", "leisure-time physical activity", "all-cause mortality", "risk of death", "mortality". 1220 studies were initially identified, 22 studies were met the inclusion criteria (5 male studies, 2 female studies, 15 both sexes). The results of this systematic review, with total 2568097 participants (aged 20-98 years), showed that any level of PA had health benefits compared to inactivity and sedentary lifestyle. The highest levels of PA had the lowest risk of all-cause mortality. In conclusion, there is an inverse relationship between LTPA and the risk of all-cause mortality, and the harmful effects of physical inactivity may be largely eliminated among those who are most active. So, promoting regular LTPA is strongly associated with well-being, quality of life and reduced the risk of all-cause mortality both in general adult population and elderly population with chronic diseases.
- СтавкаPhysical Activity and Quality of Life among High School Teachers: A Closer Look(MDPI, 2024) Živković, Danijela; Milanović, Ljubica; Ðošić, Anđela; Vulpe, Ana-Maria; Purenović-Ivanović, Tijana; Zelenović, Milan; Ioan Tohănean, Dragos; Pantelić, Saša; Sufaru, Constantin; Ioana Alexe, CristinaBackground: Understanding the relationship between teachers’ physical activity (PA) and quality of life (QoL), which is impacted by work-related stress, could help develop guidelines for improvement. The purpose of this study was to investigate the impact of physical activity on high school teachers’ quality of life and the differences in QoL and PA between male and female teachers. Methods: The sample consisted of 499 respondents (193 men and 306 women), all working in the educational system. The International Physical Activity Questionnaire (short form) was used for PA assessment, and the WHOQoL questionnaire to measure QoL. Results: Physical health and Psychological health domains were areas where male teachers scored better (p < 0.01, both), while female teachers had higher scores in Social relationships domain (p < 0.05). Regression analysis showed that PA affects Physical health: Sig. = 0.056; Psychological health: Sig. = 0.000; Social relationships: Sig. = 0.001; Environment: Sig. = 0.021 in men, and Physical health (Sig. = 0.009) and Psychological health (Sig. = 0.039) in women. Conclusions: The findings of this study allow us to conclude that, whereas female teachers’ PA primarily impacts their physical and psychological domain, male teachers’ PA has an impact on their overall QoL.
- СтавкаSports Games and Motor Skills in Children, Adolescents and Youth with Intellectual Disabilities(MDPI, 2023) Aksović, Nikola; Dobrescu, Tatiana; Bubanj, Saša; Bjelica, Bojan; Milanović, Filip; Kocić, Miodrag; Zelenović, Milan; Radenković, Marko; Nurkić, Filip; Nikolić, Dejan; Marković, Jovan; Tomović, Milena; Vulpe, Ana-Maria(1) Background: Sports games are one of the best ways of engaging in physical activity for individuals with intellectual disabilities (ID) and Down syndrome (DS). This systematic review of the current literature aims to identify and sum relevant data on motor skills and clarify whether there are positive effects of sports programs in motor skills games in children, adolescents, and youth with ID and DS. (2) Methods: The systematic review of the papers was carried out following the methodological guidelines and by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) consensus. The following electronic databases were researched: PubMed, MEDLINE, Google Scholar, ScienceDirect, and ERIC from 2001 to 2023. (3) Results: The basketball test battery can be used to improve and monitor basketball training. Basketball players with lower levels of ID achieved better results, especially those with disabilities of the II and III degrees. Futsal has a positive impact on the coordination, and the differences between the test results of the vertical jump with and without an arm swing, that can be seen indirectly as a coordination factor, were statistically significant. (4) Conclusions: Basketball is recommended as an effective and practical rehabilitation program for children, adolescents, and youth with ID and DS. Futsal is an interesting and helpful activity for individuals with ID as well.
- СтавкаSports Injuries in Basketball Players: A Systematic Review(MDPI, 2024) Aksović, Nikola; Bubanj, Saša; Bjelica, Bojan; Kocić, Miodrag; Lilić, Ljubiša; Zelenović, Milan; Stanković, Dušan; Milanović, Filip; Pajović, Lazar; Čaprić, Ilma; Milić, Vladan; Dobrescu, Tatiana; Sufaru, Constantin(1) Background: The objective of this systematic review was to collect relevant data in the available contemporary studies about sports injuries of basketball players and explain differences in sports injuries relative to gender, location, sport, and position on the court; (2) Methods: The papers were searched digitally using PubMed, MEDLINE, ERIC, Google Scholar, and ScienceDirect databases, from 1990 to 2024; (3) Results: The most frequent severe injuries for both genders are knee and ankle injuries and the most frequent forms of injury are ankle sprain and ligament strain. The most frequent injuries occur during running and after contact with the ball. Shooting guards sustain the highest injury rate followed by centers and point guards, while guards have the highest rate of adductor muscle injury; and (4) Conclusions: Studies indicate that ankle and knee injuries are prevalent among basketball players, with ankle sprains being particularly prevalent. Knee injuries are more common in female basketball players, including ACL injuries. Various factors contribute to injuries, including the biomechanics of jumping, landing, sudden changes in direction, and the physical demands placed on the body during the game.
- СтавкаThe influence of motor skills on the short sprint results(IP lermakov S.S, 2021) Aksović, Nikola; Skrypchenko, Iryna; Bjelica, Bojan; Singh, R. Ram Mohan; Milanović, Filip; Nikolić, Dejan; Zelenović, MilanBackground and Study Aim: The curriculum of physical education in high schools is based on learning motor skills, as well as their development in sports sections, where the 100-meter sprint dominates. The aim of the study was to determine the influence of motor skills on the 100 m running results. Material and Methods: The research was conducted on a sample of 80 high school students in Novi Pazar and Kraljevo, aged 16 and 17 years (± 6 months). 12 variables were used to assess motor skills, three variables each: explosive power, segmental speed, repetitive power, and flexibility (standing long jump), triple jump, five jumps. For estimating segmental speed: foot tapping, hand tapping, foot tapping on the wall. For the assessment of repetitive power: lifting the torso on the Swedish bench, mixed pull-ups, squats. To assess flexibility: deep bench press, twine, stick twist. Results: Results were obtained to confirm that there is a positive influence of motor skills on the 100 m sprint results at the level of (p=.000). The results in the 100 m sprints are statistically significantly dependent on the motor skills that manifest segmental speed and explosive power. Variables (standing long jump, foot tapping on the wall and foot tapping) have a statistically significant effect on the criterion variable of the 100 m sprint. Conclusions: Recommendation to future researchers would be to conduct a study over a longer period of time with the aim of examining the biomechanical factors that determine the success in sprint, is the production of force in the phase of sprint acceleration and sprint deceleration
- СтавкаWarm-up is an efficient strategy to prevent diurnal variation of short-term maximal performance in young basketball players(Taylor and Francis Ltd., 2024) Zelenović, Milan; Kontro, Titta; Čaušević, Denis; Bjelica, Bojan; Aksović, Nikola; Milanović, ZoranThe objectives of this study were to investigate: 1) whether there were morning-to-evening differences in short-term maximal performance and 2) the impact of prolonged and specific warmup on short-term maximal performance diurnal variations in young basketball players. Fifteen basketball players of both sexes (Male = 8; Female = 7; age: 14.4 ± 0.46 yr; weight: 64.7 ± 7.1 kg; height: 175.2 ± 6.6 cm; BMI: 21.1 ± 1.9 kg/m2) completed the following short-term maximal performance tests: CMJ with and without arm swing, Lane Agility Drill, Zig-Zag agility test with and without the ball, Sprint 20 m with and without the ball with the passage at 5 and 10 m. All tests were performed after the 15-min standard warm-up procedure (with static stretching) and/or 25- min specific warm-up (with prolonged running and dynamic stretching) in the morning and evening. Vertical jumping tests and all change-of-direction speed tests (with and without a ball) with superior responses were achieved in the evening after standard warm-up among all participants (p < 0.05). In contrast, superior short-term maximal performance was observed in the morning after prolonged and specific warm-up protocol (p < 0.05). It was concluded that specific and prolonged warm-up protocols are suitable strategy to prevent diurnal variation in short-term maximal performance in young basketball players.
