The purpose of study is to determine the effectiveness of the influence of strength fitness on the development of motor abilities of high school students.
Materials and methods. The study was ...conducted on the basis of secondary school No. 55 Kharkiv in several stages. During the study, two groups were created: experimental and control. The control and experimental groups included 10 boys of 10 grade each. In the control group, lessons were held on the module “Gymnastics” according to the thematic plan. And in the experimental group the lessons content included: strength fitness, stretching exercises and aerobic combinations. Special attention was paid to the preparation of muscles for performing the exercises of the main part of the lesson - strength training. Research methods: study, synthesis and comparative analysis of literature and other sources on the research issue; observation; questionnaires, diagnosis of well-being, activity, mood according to the WAM method, testing of motor readiness, methods of mathematical statistics.
Results. According to the study results, in the experimental group was found a probable improvement in the state of activity by 11.3 points (p<0.01) and mood by 12.7 points (p<0.01). This indicates the positive impact of strength fitness exercises, modern music accompaniment and the corresponding load on these indicators. In the control group under the program of the variable module “Gymnastics” we observed an improvement in strength abilities such as flexion and extension of the arms in the abutment position by 3.8 (p<0.05). Indicators of motor abilities of students in the experimental group at the end of the trial had probable shifts towards improvement: shuttle run 4×9 m by 0.9 sec. (p<0.01), flexion and extension of the arms in the abutment position by 3.9 times (p<0.05), flexion and extension of the arms in suspension by 1.5 times (p<0.05), bent suspension by 7.4 sec. (p<0.001), jump in length from the place by 7.4 cm (p<0.05), flexibility (torso inclination) by 3.1 cm (p<0.001).
Conclusions. The use of recreational fitness in physical education classes in high school students not only contributes to an increase in the level of motor abilities, but also improves the emotional state of students. Through a combination of physical education, aerobic exercise, stretching, strength fitness, breathing exercises, visualization, high school students noted an improvement in well-being, mood, and activity.
Introduction
The full-scale war with Russia on the territory of Ukraine has revealed several problems related to care of the wounded. In this article, we summarize the mechanisms of injury and ...injuries sustained for the period February to April 2022, focusing on extremity injuries.
Materials and methods
We compared these to a period of lower-intensity warfare in 2014–2021. In both cases, we report patients treated by the National Military Medical Clinical Center (NMMCC) in Kyiv. We also sought to evaluate the care of the wounded from an organizational viewpoint, taking into account the four-level system of care also used by the North Atlantic Treaty Organization (NATO). Third, we sought to understand lessons learned that could improve the care of the wounded.
Conclusion
During the 2022 conflict, the percentage of patients with extremity wounds who had long bone fractures increased and the percentage of people with long bone fractures who had bone defects increased, compared with 2014–2021. This may be due to the higher blast energy from the weapons used in the current conflict. Second, we adapted the four-level NATO system of care. Level 2 (first level hospital) care was provided by civilian hospitals close to the fighting, rather than mobile military hospitals. Level 3 (specialized) and 4 (highly specialized) care were combined into one hospital (NMMCC). This is the first description of flexible use of NATO's four levels. Finally, a major lesson learned was the need to improve use of damage control surgery.
•Russo-Ukrainian war is associated with both severe injuries and severe bone defects due to frequent application of high-energy weapon.•3D-printing and polyetheretherketone (PEEK) implants could be ...used in management of combat patients with severe bone defects > 10 cm.•Closed reduction, percutaneous lag screw for distinct compression, ilizarov external fixation are appropriate methods to treat severe bone defects.•Fibula on a vascular pedicle could be used as a graft to replace severe bone defects in combat patients with injuries to the long bones.
Russo-Ukrainian war is associated with application of high-energy weapon, causing severe multifragmental injuries to the bones an associating with severe bone defects.
The aim of the study was to evaluate various methods to treat combat patients with severe defects of humerus and to demonstrate the experience of orthopedic war surgeons in managing gunshot injuries to the humerus defects in the ongoing war.
A 24 patients were active-duty military personnel of Armed Forces of Ukraine. These patients were diagnosed with severe humerus defects due to gunshot injury in battlefield zone in various areas of Ukraine. Data was collected within period between February, 24th 2022 till January, 01st 2023. The following approaches were applied to replace bone defect: preoperative 3D printing with polyetheretherketone (PEEK) as orthobiological material; closed reduction, percutaneous lag screw and Ilizarov external fixation; vascularized fibula grafting.
Data analyses of the segmental defects of humerus showed 5 cm defect in 3 (13 %) patients, from 5 to 10 cm in 4 (17 %) patients, over 10 cm in 17 (71 %) patients. Analyses were performed in these 17 (71 %) patients, showing 5 patients treated with 3D-printed PEEK implants, 6 patients with vascular-pedicle graft of fibula, 6 patients with closed reduction, percutaneous lag screw, Ilizarov external fixation. Osteomyelitis was diagnosed in one case (20 %) after the use of PEEK implants, requiring to remove both PEEK implant and metal implants followed by application of the antibiotic joint spacers and Ex-Fix fragments of the humerus. In our opinion, the osteomyelitis happened due to inadequate debridement of the wound and non-compliance with the conversion criteria (replacement of the fixation method). The mean length of hospital stay was 5.5 months for patients treated with 3D-printed PEEK implants.
Closed reduction, percutaneous lag screw and Ilizarov external fixation as well as vascularized fibula grafting are associated with good outcomes in management of the patients with severe humerus defect due to gunshot injury. 3D printing and PEEK implants could also be considered for the reconstructions of the humerus multifragmental fractures with a bone defect over 10 cm associated with gunshot injury due to high-energy weapon in the war settings.
