    Effect 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 Iulian
    Introduction: (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.

    Effects of Repeated Sprint Training in Hypoxia on Physical Performance Among Athletes: A Systematic Review
    (Jyväskylän yliopisto, University of Jyväskylä, Finland, 2021) Zelenovic, Milan; Kontro, Titta; Stojanovic, Tijana; Alexe, Dan Iulian; Bozic, Danijel; Aksovic, Nikola; Bjelica, Bojan; Milanovic, Zoran; Adrian, Sava Mihai
    Repeated sprint training in hypoxia (RSH) represents an innovative method in the process of development and improvement of physical performance among athletes. However, there is less scientific data on this topic. The purpose of this systematic review was to investigate the effect of RSH method on motor abilities and performance among athletes, obtain new information, and expand the already known conclusions. The data search was performed of 4 electronic databases for the years 2000-2021 May as follows: Google Scholar, PubMed, Web of Science, and ResearchGate. This search with English language restriction was made by using the following terms, individually/combination: "repeated sprint ability", "hypoxia", "effects", "physical performance", "VO2max" 844 studies were indentified, and 14 studies were selected (11 male studies, 1 female study, 2 both sexes). Results of this systematic review, a total sample size of 347 athletes (40 females and 307 males, aged 15.3 ± 0.5 - 35 ± 7 years), showed that RSH was an effective training method in improving all monitored variables (i.e. RSAmax, VO2max). However, it should be noted that major improvements were observed mainly in repeated sprint ability (RSA) tests, and less in aerobic tests (i.e. Wingate and Yo-Yo). In conclusion, based on current scientific studies, RSH is more effective method to improve the physical performance among athletes compared to repeated sprint training in normoxia (RSN). This study suggested that the RSH has a positive effect on the monitored variables in physical performance tests especially related to RSA.

    EFFECTS OF TACTICAL GAME+ENCOURAGEMENT ON IMPROVE DECISION MAKING AND SKILL EXECUTION IN BASKETBALL ATHLETES
    (Asociacion Canaria de Psicologia del Deporte, 2023) Rusmana, Ruslan; Sulaiman, Iman; Rihatno, Taufik; Chaniago, Herman; Samsudin; Asmawi, Moch; Wiradihardja, Sudradjat; Bahtiar, Bahtiar; Supriad, Dedi; Alexe, Dan Iulian; Gazali, Novri; Pavlović, Ratko; Setiawan, Edi
    This study aims to investigate the effect of TG+E on increasing DM and SE among basketball athletes through true experimental research with a 12 week randomized controlled trial design. The participants involved basketball athletes from the Pasundan Teacher Training and Education College (Indonesia), totaling forty people. Participants were allocated in TG+E (n = 20) and CG (n = 20) groups. The instruments for measuring DM and SE were direct observation and camera recording. Non-parameteric with the Mann–Whitney U test was chosen for analysis between TG+E and CG in the initial-test and final-test. The results of this study showed significant differences in all DM and SE variables in TG+E from initial-test until final-test related to Inside shooting (p < 0.05), Outer shooting (p < 0.05), Passing to zone (p < 0.05), 6.25 m passing (p < 0.05), Far passing (p < 0.05) and Dribbling to zone (p < 0.05). Meanwhile, in CG the differences only occurred in DM and SE which was related to Passing to zone (p < 0.05), 6.25 m passing (p < 0.05), and there was no difference in other aspects. Thus, we emphasize TG+E as an alternative and training solution to improve the quality of DM and SE among basketball athletes.

    Leisure-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 Cristian
    Many 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.
