Influence of high and moderate intensity circuit physical exercise on reduction of body fat and visceral fat in female population

Prekomjerna tjelesna težina i pretilost postali su ozbiljan problem javnog zdravlja širom svijeta. U ovom istraživanju uspoređivali smo utjecaj i odnos kružnog treninga različitih intenziteta kod ženske populacije. Istraživanje je provedeno na populaciji 60 žena u dobi 18-40 godina. Ispitanice su raspoređene u jednu od tri grupe: kontrolna grupa; grupa koja vježba umjerenim intenzitetom; grupa koja vježba visokim intenzitetom. Eksperimentalni postupak sastoji se od dva testiranja, koja će se provesti u dvije vremenske točke i 12-tjednog programa djelovanja na sastav tijela ispitanica (tjelesno vježbanje visokog intenziteta i tjelesno vježbanje umjerenog intenziteta u kružnom obliku rada).Uzorak varijabli sačinjavalo je 17 antropometrijskih mjera. Sastav tijela bio je procijenjen na tri različita načina: bioimpendancijom; algoritmom baziranom na mjerenju 9 kožnih nabora; zračnom pletizmografijom. Ventilacijski i metabolički parametri biti će izmjereni spiroergometrijskim sustavom i progresivnim testom opterećenja na pokretnom sagu. Bazalni metabolizam u mirovanju biti će mjeren u mirovanju spiroergometrijskim sustavom. Opterećenje na programima vježbanja praćeno je uz pomoć monitora srčane frekvencije. Količina visceralne masti bit će mjerena pomoću Tanite AB 140. Ciljevi ovog istraživanja su utvrditi utjecaj tjelesnog vježbanja visokog intenziteta i tjelesnog vježbanja umjerenog intenziteta na redukciju potkožnog masnog tkiva i visceralne masti kod žena te ih komparirati. Postavljene su tri hipoteze: 1. Kod ispitanica koje su bile podvrgnute programu tjelesnog vježbanja umjerenog intenziteta postignuta je statistički značajna promjena količine PMT-a i količine visceralne masti; 2. Kod ispitanica koje su bile podvrgnute programu tjelesnog vježbanja visokog intenziteta postignuta je statistički značajna promjena količine PMT-a i količine visceralne masti; 3. Kod ispitanica koje su bile podvrgnute programom tjelesnog vježbanja visokog intenziteta postignuta je statistički značajno veća promjena u količini PMT-a i količini visceralne masti u komparaciji s ispitanicama koje su bile podvrgnute programu tjelesnog vježbanja umjerenog intenziteta. Prve dvije hipoteze su djelomično prihvaćene jer su primijećene statistički značajne razlike u rezultatima između inicijalnog i finalnog testiranja unutar pojedine grupe, dok je treća odbačena jer nisu zamijećene statistički značajne razlike u rezultatima između različitih intenziteta kružnog tjelesnog vježbanja. Rezultati ovog istraživanja nastavak su na različite zaključke što se tiče efikasnosti ove dvije organizirane aktivnosti jer istraživanja koje uspoređuju visoko intenzivne aktivnosti i umjereno intenzivne aktivnosti pokazuju kontraverzne rezultate.Excessive weight and obesity have become a serious public health problem around the world. In this study, we compared the influence and relationship of circular training of different intensities to the female population. The study was conducted on a population of 60 women aged 18-40. Subjects were divided into one of three groups: control group; a group exercising with moderate intensity; a group exercising with high intensity. The experimental procedure consists of two tests, which will be carried out in two time points and a 12-week program of action on body composition (physical exercise of high intensity and physical exercise of moderate intensity in circular form). The sample of variables consisted of 17 anthropometric measurements. The body composition was evaluated in three different ways: bioimpendancy; an algorithm based on the measurement of 9 skin folds; by air plethysmography. Ventilation and metabolic parameters will be measured by a spiroergometric system and a progressive load test on a treadmill. Residual basal metabolism will be measured at rest by the spiroergometric system. Exercise load was monitored with the help of a heart rate monitor. The amount of visceral fat will be measured using Tanita AB 140. The objectives of this study are to determine the effect of high intensity physical exercise and moderate physical exercise on the reduction of subcutaneous fat and visceral fat in women and to compare them. Three hypotheses were introduced: 1. In subjects who performed a moderate intensity exercise program, a statistically significant change in the amount of PMT and the amount of visceral fat was achieved; 2. In subjects performing high intensity physical exercise program, a statistically significant change in the amount of PMT and the amount of visceral fat was achieved; 3. In subjects performing high intensity physical exercise program, a significantly higher change in the amount of PMT and the amount of visceral fat was achieved in comparison with subjects who performed a moderate intensity exercise program.The first two hypotheses were partially accepted because of the statistically significant differences in the results between initial and final testing within each group, while the third was rejected because no statistically significant difference in the results between the different intensity of circular physical exercise was observed. The results of this research are connected to various conclusions regarding the effectiveness of these two organized activities, because researches that compare highly intensive activities and moderately intensive activities showed contradictory results

Cardiorespiratory Fitness and Health-Related Quality of Life in Secondary School Children Aged 14 to 18 Years: A Cross-Sectional Study

The main aim of this study is to examine age and gender differences in cardiorespiratory fitness (CRF) among Serbian secondary school children. The secondary aim is to explore the association between CRF and quality of life in Serbian adolescents. The sample consisted of 579 adolescents (285 males), aged from 14 to 18 years old. To evaluate their anthropometric measurements, body height and body weight were examined, the 20 m shuttle run test was used to access CRF, and the standardized global measure of wellbeing KIDSCREEN was used to access the wellbeing of adolescents. The results show that the boys possessed higher CRF compared to the girls, as well as higher scores on variable distance, but there were no significant differences according to age. CRF was positively associated with physical wellbeing, psychological wellbeing, total score HRQL, body height and body weight, and negatively correlated with BMI. Conversely, physical wellbeing showed positive correlation with the other subscales of KIDSCREEN (psychological wellbeing, autonomy and parents, peers and social support, and school environment), and total score of (Health–Related Quality of Life) HRQL. The results showed that better CRF would be beneficial for quality of life among Serbian adolescents, especially among girls. Moreover, the relationship between CRF and BMI shows that adolescents with regular values of BMI have better physical fitness and wellbeing

School-Based Exercise Programs for Promoting Musculoskeletal Fitness in Children Aged 6 to 10

Musculoskeletal fitness (MF) is a multidimensional construct that combines muscle strength, endurance, and power to allow for the performance of tasks against one’s own body weight or an external resistance. The aim of this study was to determine the effects of school-based programs on promoting MF in children aged 6 to 10. PubMed and Web of Science databases were used as searching tools. A total of 16 studies were included in a systematic review with primary school-based program interventions measuring at least one variable related to musculoskeletal fitness. Parameters for measuring explosive power, especially standing broad jump (SBJ), have a large potential for development throughout school-based programs. Long-lasting interventions did not necessarily improve MF; however, there were shorter interventions that caused the improvement in a larger number of parameters. Our findings imply that increased physical activity during a school week, together with improved lesson content, is crucial for MF development in this age group

Test of Motor Proficiency Second Edition (BOT-2) Short Form: A Systematic Review of Studies Conducted in Healthy Children

Motor skill competence of children is one of the important predictors of health because if a child is physically active during early childhood, the possibility of occurrence of many chronic diseases in adulthood will be reduced. The aim of this study was to systematically review the studies conducted in healthy children using the shorter form of the Bruininks-Oseretsky (BOT-2) and to determine the applicability in cross-sectional studies and pre-post designs. The search and analysis of the studies were done in accordance with the PRISMA guidelines. An electronic databases search (Google Scholar, PubMed, Mendeley, Science Direct, and Scopus) yielded 250 relevant studies conducted from 2011 to 2020. A total of 21 studies were included in quantitative synthesis, with a total of 3893 participants, both male and female. Through this study, the BOT-2 test proved its broad applicability, so it can be concluded that this test can be used to improve motor proficiency in a healthy population of children. Hence, it is necessary to invest a lot of time during the implementation of various programs so that children would adequately develop their basic motor skills so they broaden their own repertoire of movements

8th international scientific conference on kinesiology: 20th anniversary : proceedings

We are exceptionally happy that we can greet you once more on this occasion. The Faculty of Kinesiology, as a proud member of the University of Zagreb and a higher education institution that is 57 years old, is organizing The International Scientific Conference on Kinesiology for the 8th time. Identically as three years ago, this is a good opportunity to remember some important anniversaries. First of all, this year we celebrate 160 years since Nicolas Dally published his work in 1857 under the title “Kinesiology – Science of Movement in Relation to Education, Hygiene and Therapy”. This was the first book that introduced Kinesiology as a science of movement. The second important anniversary is 20 years since the establishment of our Conference. In 1997 the first International Scientific Conference on Kinesiology was held in Dubrovnik. Until today a great number of leading experts in the field of contemporary kinesiology were keynote lectures and presenters of the most important scientific breakthroughs in the field. Once again, the Conference will be a great opportunity for broadening of scientific insights into this miraculous, beautiful phenomenon of physical activity and its effects – its perfection when performed by sport artists, as seen at the XXXI Olympic Games, its joyfulness when happy children enjoy being competent to be in motion, or when we see eager people who enjoy life and nature because they have enough energy and they are healthy thanks to an active lifestyle. We are especially proud of the 17th place on the medal list thanks to the ten Olympic medals won by Croatian athletes. All fundamental and applied fields of our science will be discussed within 10 tentative sessions and 3 Satellite symposiums. The ultimate purpose of papers or abstracts published in this Proceedings book is to know and understand human beings and to apply the findings in everyday practice of education, sports, health promotion, recreation, sports management and kinesitherapy. The Proceedings Book contains 249 contributions, which were submitted by the submission deadline, written by 557 authors from 30 countries from all over the world. We expect a number of graduate, doctoral and postdoctoral students from Croatia and abroad for whom the Conference School of Kinesiology for Postgraduate and Doctoral Students will be organised during the Conference. From the very beginning the Croatian Academy of Sciences and Arts has given its highly respected patronage to the Conference, thus underpinning the recognition of kinesiology in the structure of sciences. Special thanks go to our partner institutions: Beijing Sports University, China and the Faculty of Sports Studies, Masaryk University, Brno, Czech Republic, to our collaboration institutions: the Lithuanian University of Educational Sciences, Lithuania, the Otto-von-Guericke University, Magdeburg, Germany and the Faculty of Sport and Physical Education, University of Novi Sad, Serbia. We wish to express much gratitude to all the authors, reviewers, participants, members of the Organisation and Program Committee, Section Editors, technical support staff, and sponsors for their contributions, time and effort inbuilt in the quality of the 8th International Conference on Kinesiology and its Proceedings. We wish success in the conference work to all the participants and a pleasant time in Opatija. Convinced that the Conference will give the expected impetus to further cooperation between scholars and institutions, we are looking forward in advance to meeting you again at the 9th International Conference on Kinesiology in 2020.
