Rapid weight loss habits before a competition in sambo athletes
No full textBackground: Like other combat sports, sambo has competition rules that divide athletes into categories based on gender, age and weight. Athletes in combat sports often resort to rapid weight loss (RWL) methods to be more competitive in lower weight categories and gain an advantage against lighter, smaller and weaker competitors. The aim of this study was to examine the methodology implemented by two different sambo age categories, junior and senior athletes, in order to attain RWL. Methods: The sample consisted of 103 male sambo elite athletes (seniors/juniors: age 28.5 ± 4.3/18.9 ± 0.8; height (m): 1.7 ± 0.1/1.8 ± 0.1; weight (kg): 76.3 ± 17.8/74.4 ± 16.3; BMI (kg/m2): 25.0 ± 3.8/23.7 ± 3.9) who completed a survey on RWL. Results: Athletes reported losing a mean of 5 kg starting approximately 12 days before a competition. The most common methodology reported by senior and junior sambo athletes was gradually increasing dieting, followed by sauna and plastic suit training. Less common methods adopted were laxatives, diuretics, the use of diet pills and vomiting. There were significant group differences for sauna and diet pill ingestion. Coaches and parents are influential people in the lives of athletes concerning the weight loss strategy to be adopted. Conclusions: This study’s results unequivocally confirm the prevalent practice of RWL in both senior and junior sambo athletes. Although athletes prevalently chose “less harmful” methods, there is a need to inform parents and coaches of the risks and benefits of RWL

Patterns of rapid weight loss in elite sambo athletes
No full textBackground: Rapid weight loss (RWL) is commonly practiced in combat sports. Both magnitude and methods used to induce RWL are largely similar among combat sports, but currently, there is no data on RWL methodology used by sambo athletes. Therefore, the aim of this study was to determine RWL procedures sambo athletes apply to lose weight rapidly. Methods: The sample consisted of 199 participants, of which 132 males and 67 females who participated in the World Sambo Championship 2020 held in Novi Sad, Serbia. Each participant received RWL questionnaire that was available in multiple languages, and every participant was instructed how to fill it out. Results: Almost 87% of sambo participants declared to have intentionally cut their weight prior to the competition, whereby 5.27 kg (SD: ±7.57) was lost. Gradual dieting, sauna use and skipping meals were the most dominant methods used to reduce weight prior to competition while more extreme methods of RWL such as the use of laxatives, diuretics, diet pills and vomiting were also implemented but by much smaller fragment of the participants involved. Conclusions: Findings from our study largely match with previously conducted RWL studies in terms of prevalence, magnitude and methods used by combat sport athletes, especially in judo and wrestling. Knowing the hazardous consequences of RWL, alternative methods of sustainable weight loss should be considered
Are optical tools suitable to manage phosphate and potassium fertigation in tomato crops?
No full textLa fertirrigazione in orticoltura
No full textAbstract. In the last decade in Italy, fertigation has been increasing in vegetable crops production in both green-house and in open field cultivation. Fertigation, combining irrigation and fertilization, results effecti- vely in increasing both water and nutrient efficiency when correctly applied. Besides improving yield and quality of the crops and helping to minimize manage- ment costs, fertigation reducing mineral nutrient sup- ply is also beneficial for the environment by minimi- sing mineral leaching and nutrient losses. Application of low concentrations of nutrients results in lower accumulation of harmful compounds such as nitrates from nitrogen application. Correctly applied fertigation requires knowledge of both water and nutrient needs of the species and the characteristics of the soil. Fertigation could be applied to any irrigation system although the highest efficiency is reached by microirri- gation systems such as drip irrigation and sub-irriga- tion. In this paper, all parameters involved in fertiga- tion management are discussed, and information for a correct application of the technique are given. The nitrogen, phosphorous and potassium mineral needs of the most important vegetable crops are reported; daily elemental uptake of tomato for both processing and fresh market, eggplant, melon and lettuce are discussed. In addition to advice for an effective ferti- gation application, advantages and disadvantages are also analysed. References listed at the end of the paper can provide for further subject information

(спортивний розділ) в положенні лежачи під час захисту. Визначено існуючі педагогічні моделі (технології), методики, організаційно-педагогічні умови тощо, які
забезпечують підготовку висококваліфікованих самбістів та самбісток до змагальної діяльності.Respectively to the results of the monitoring of
specialized of scientific and methodological literature, members of the scientific research group, what are the problems of designing
a relatively technical and tactical arsenal of athletes (sportswomen), who specialize in Sambo wrestling of different age groups and
weight categories – attributed to the lack of a certain amount of research, which adds to the relevance and practical warehouse of
the directly collected scientific research.
The main method of scientific achievement is the designation of a technical arsenal of rare techniques for Sambo
wrestling (sports division) in the lying position for an hour of defense.
As a result of the theoretical research, the members of the scientific research group identified a technical arsenal of
common techniques for Sambo wrestling (sports division) in the lying down position for an hour of defense. Analyzing the results
of taking away, for example, the final stage of the theoretical study, we have identified the onset of a 7 groups of rare technicaltactical wrestling Sambo in the lying position for an hour of defense.
Inclusion of the listed above of a Sambo type of designation of more groups of technical and tactical wrestling of Sambo
(sports division) in the system of long-term training of athletes and female athletes, as they specialize in Sambo wrestling of
different age groups and categories of wrestling in the future will contribute to increasing the indicators of their participation in
competitions. This, in turn, will contribute to improving the image of Ukraine on the world sports arena.Исследован технический арсенал редких приемов борьбы самбо (спортивный раздел) в положении лежа при защите.

Incorporating specific sambo exercises into distance learning for high school students aged 15-16
No full textBackground and Study Aim. The military situation in Ukraine necessitates a revision of the school class organization system. Proximity to the military contact line forces schools to switch to online learning. Additionally, there is a decrease in physical activity among school students. In these conditions, it is important to explore the effectiveness of using specific sambo exercises to develop physical qualities in high school students during distance learning. The aim of the study is to determine the effectiveness of such application of sambo exercises for the development of physical qualities in high school students in a distance learning format.
Materias and Methods. The study involved tenth-grade students (n=15), aged 15-16 years. Data collection was conducted through surveys using Google Forms and testing to determine physical quality indicators. The experiment lasted for 8 weeks (with sessions three times a week), during which specific sambo exercises were applied in a remote format during physical education lessons.
Results. The study results showed that 80% of the students were interested in implementing a new module - sambo - in physical education lessons. Correlational links were established between the results of the exercises and indicators of strength, flexibility, and coordination. Moreover, there was a significant improvement in the test results for coordination, flexibility, and strength, averaging 20%.
Conclusions. The study results indicate significant interest among high school students in implementing specific sambo exercises in a distance learning environment. This is confirmed by the high percentage of students who expressed a desire to practice sambo during physical education lessons
