THE EFFECT OF THE INTERVAL TRAINING METHOD ON THE SPEED ENDURANCE OF FOOTBALL PLAYERS

During the competitive activity of football players, maintaining a high level of energy supply for ensuring muscle activity and special physical performance is a priority issue. Therefore, achieving and maintaining a high level of physical performance is an important factor that ensures the result. The purpose of the research is to study the effect of interval training method on speed endurance of football players. The following research methods were used: analysis of scientific and methodological literature, pedagogical scientific experiment, mathematical statistics. To achieve the set goals, particularly within the framework of improving speed endurance indicators, the interval training method was chosen for comparison with small-sided games in a square as part of the research. The research was carried out in 2022, in January-February, at Football Academy of Gyumri. 28 football players of "Shirak" and "Shirak-2" aged from 17 to 20 participated in the research: 14 athletes in experimental group and 14 in control group. Research result analysis: In the training system for football players, practically every session involves simultaneous work in multiple power zones, where quick movements occur in both maximum and submaximal zones. This, in turn, contributes to the reduction of both creatine phosphate and glycogen reserves in the muscles. To ensure the proper level of recovery for various energy substrates, it is necessary to carefully select methods and means to achieve the set goals, promoting the growth of both the organism functional capabilities and the concentration of macro ergonomic compounds. This is aimed at increasing speed-strength performance and endurance. During the 6 weeks, the football players trained five times a week, using the interval method once a week in the first, third and sixth weeks and twice in the second, fourth and fifth weeks, respectively. As an interval method 8 times 35m running at maximum speed with 1.5 minute rest intervals (slow running) was used in the experimental group. The control group performed a two-minute game in a square (12x12) 5 times for 30 seconds with intervals. The results obtained during the research reveal that there were significant differences in the indicators in both the experimental and control groups, but the increase in the indicators in the experimental group was more vivid: 4.23% and 2.16%, respectively. Like the interval method, the game in the square contributes to the improvement of the speed endurance of the football players. Along with that, it was revealed that the use of the interval method is more effective for developing the speed endurance of football players. A trend of significant difference between groups was recorded (р <0.05).

Does Tennis Training Improve Attention? New Approach.

A total of 40 tennis players from a Tennis Club, 20 in the experimental group (EG) and 20 in the control group (CG), participated in the study. The EG athletes received 40 serve balls from the trainer twice a week for nine weeks. The researcher applied the "d2 attention test" to the EG and CG before and after the nine-week period. After comparing the pretest and posttest attention averages of the experimental group, there was a significant difference in the TN, TN-E, and CP mean scores (p < 0.001). In the comparison of the pretest and posttest attention averages of the CG, there was no significant difference in the TN, TN-E, and CP mean scores (p > 0.05). The comparison of the pretest attention averages of the EG and CG revealed no significant difference in the TN, TN-E, and CP mean scores (p > 0.05). The comparison of the posttest attention averages of the EG and CG revealed a significant difference in the mean scores of TN, TN-E, and CP (p < 0.05). There was a statistically significant difference between the posttest-pretest differences in the TN, TN-E, and CP values of the EG and CG (p < 0.05). The study concluded that tennis training aimed at developing attention improved the results in the attention test.

Material and methods: 16 fencers of 10-12 years old took part in the study, who at the beginning of the study trained at the «Unifeht» sports complex. The experimental group consisted of athletes (n=8), who practiced according to the developed program three times a week for 3 hours. The control group consisted of athletes (n=8), who were engaged in the standard program of the fencing department of the sports school. The study lasted 11 months. The following methods were used in the work: analysis of special literature and Internet resources; pedagogical observation; analysis of coordination readiness of young fencers; methods of mathematical statistics for processing the obtained results. Results: with the help of selected tests, the level of general and special coordination readiness was determined. The work presents the developed program for improving the coordination abilities of young fencers of the basic training group. In March, due to the military operations in the Kharkov region, the destruction of the «Unifeht» sports complex, the training was suspended. Since April, training has been resumed in various cities of Ukraine. All athletes were in constant contact and tried to adhere to the proposed program. Testing was carried out both offline and online. Under the influence of training programs, there were positive changes in all indicators of athletes of both groups. The difference between indicators in both groups for all tests is significant, p&lt;0,05. A significant decrease in the mean square deviation of experimental group athletes in tests of general coordination readiness is also noticeable. Conclusions: Extremely difficult conditions in which the research was conducted significantly affected the result. The effectiveness of the developed program to increase the level of coordination abilities of 10-12-year-old fencers has been proven. At the end of the study, there were positive changes in both groups.

EFFECT OF DYNAMIC TRAINING PROGRAM DESIGNED BASED ON THE TABATA PROTOCOL ON BALANCE AND STRENGTH PARAMETERS OF ELITE LEVEL COMBAT ATHLETES

The purpose of this study was to investigate the effects of a 6-week dynamic training program designed based on the Tabata protocol on balance and strength parameters of elite level combat athletes. This randomized controlled experimental study with pre-test and post-test was conducted with 25 randomly selected elite level combat athletes who volunteered to participate in the study, 12 in the experimental group (5 wrestling, 2 judo, 2 karate, 3 taekwondo) and 13 in the control group. In the pre-test and post-test stages of the study, Biodex Balance SD (Biodex Inc., Shirley, NY) balance device was used to determine static and dynamic balance performances of the athletes. The strength performance of the athletes was determined by measuring back, leg, and grip strength using a back-leg dynamometer (TKK 5402) and a hand grip dynamometer (Takei). After data collection, SPSS 25.0 was used for statistical analysis of the data and the significance level was set at p&amp;lt;0,05. At the end of the study, it was determined that the differences between pre-test and post-test body weights and eyes open and closed dynamic balance levels of the experimental group athletes were statistically significant (p&amp;lt;0,05), whereas the differences between the measurement results of control group athletes were not significant (p&amp;gt;0,05). The Tabata protocol is a high intensity interval training technique and is effective on aerobic-anaerobic energy systems. The movement determined for the session is repeated intensely, rhythmically, and continuously during the exercise window. As a result, the Tabata protocol supports dynamic balance and strength improvement of elite combat athletes through dynamic exercises.

A total of 44 U18 volleyball athletes participated in the study, divided into two groups: experimental group ( n = 23) and control group ( n = 21). The Declarative Tactical Knowledge Test in Volleyball was used for the decision-making analysis, while the Instrument for Technical-Tactical Performance Assessment in Volleyball was used for the specific tactical-technical performance components level analysis in the game. Experimental group athletes performed 24 training sessions using the Pendular Model, and control group athletes maintained 24 sessions of regular training. There was a significant difference in decision-making in the extremity attack and setting situations, being better in the experimental group than the control group in the pre and postintervention moments. There were significant differences in the adjustment, decision-making, and effectiveness components in athletes’ tactical-technical performance in game situations, being greater in the experimental group compared to the control group in the moments after 12 sessions and postintervention. It is concluded that the Pendular Model proved to be effective for improving decision-making in extremity attack and setting video situations and in the tactical-technical performance in the game in the adjustment, decision-making, and effectiveness components for male U18 volleyball athletes.

Удосконалення фізичної підготовленості спортсменів у класичному пауерліфтингу на етапі підготовки до вищих досягнень на основі використання планування компонентів навантаження в групах вправ

Despite the active development of classical powerlifting in recent decades, the construction of training athletes in this division was based on the scientific achievements of researchers in equipment powerlifting, based on abrupt planning of sports volume and intensity of increasing load in the structural. Taking into account the impossibility of using significant indicators of volume and intensity in classical powerlifting, it is important to study ways to improve the construction of training powerlifters of different qualifications. The purpose of the study was to substantiate the effectiveness of the application of load component planning in groups of exercises in building the training of athletes in classical powerlifting at the stage of preparation for higher achievements. Material and methods. To achieve this goal we used theoretical analysis and generalization of data from scientific and methodological literature and the world information network Internet; documentary method; pedagogical observation; pedagogical experiment; methods of mathematical statistics. Based on the analysis of existing scientific knowledge and best practices, the need to find ways to improve training programs for athletes in classical powerlifting at the stage of preparation for higher achievements as one of the most important structural elements of athletes' athletic potential was substantiated. Results and discussion. As a result of the pedagogical experiment, there were significant differences in the performance of athletes of the control and experimental groups before and after the experiment in two of the four tests. Significant differences between the indicators of physical fitness of athletes in the control and experimental groups after the experiment were found in tests aimed at determining the level of development of strength capabilities. In two tests we found no significant differences between the indicators of the athletes of the experimental and control groups. Conclusion. The results of pedagogical experiment revealed reliable indicators of growth of physical fitness in three tests in athletes of experimental and control group. There were no reliable growth rates in both groups after the pedagogical experiment in the test "Running 30 m from a high start". The indicators of growth of physical fitness in the tests "Pull-up on the crossbar" and "Jumping from a place" in the athletes of the experimental group were higher than in the control group, which confirmed the higher efficiency of the author's powerlifters training program. Conclusion. Thus, planning load components in different groups of exercises in microcycles in accordance with their focus in the training of powerlifters in preparation for higher achievements allowed ensuring a sufficient level of adaptive shifts to increase athletes preparedness on the background of reducing the total annual load

Influence of osteopathic correction on the functional state of the athletes′ organism during the training process of martial arts practicing (Kendo)

Introduction. One of the widespread and massively practiced martial arts is a Kendo — a system of fencing with a Japanese sword. Herewith the training process imposes very high requirements on athletes practicing martial arts. Large physical and psychological loads often lead to overstrain of various organism systems. This worsens the functional state of the organism and causes various injuries. But very often athletes in this situation continue training and take part in competitions. As a result a further deterioration of the condition and delayed recovery of the functional state of the organism takes place, and it negatively affects sports results. In Russia, this type of martial arts is massively engaged in the first generation of athletes, so today there are no methods of treatment, recovery and medical support specially developed for this sport. Osteopathy can be a promising method of drug-free recovery and maintenance that does not require the use of complex equipment, and this method has already proved itself well in some other sports.The goal of research — to identify the somatic dysfunctions that are typical for kendoists and can affect their sports results, and to study the impact of osteopathic correction on the osteopathic status and the kendoists organism′ functional state, which determine the athletes performance.Materials and methods. 30 athletes practicing Kendo were selected to participate in the study. A simple randomization method was used to form an experimental group (15 people) who had osteopathic correction of somatic dysfunction (SD), and a control group (15 people) in which there were no any manipulations. At the beginning of the study both groups underwent osteopathic examination and assessment of the organism functional state by the Harvard step test and a breath-holding test (Genchi test). Osteopathic correction of SD in the experimental group was performed once a month for 9 months. Then the osteopathic examination and functional assessment were repeated in both groups. The obtained results were compared both within the respective groups (using the Wilcoxon test) and between groups (using the Mann–Whitney test).Results. The following regional biomechanical disorders were detected as typical for the selected Kendo athletes at the study beginning: lower extremities (structural component), thoracic region (structural and visceral component), and lumbar region (structural and visceral component). Such characteristic local somatic dysfunctions as dysfunctions of the ankle and subtalar joints were also identified. The use of SD osteopathic correction in athletes of the experimental group led to a statistically significant decrease in the SD total number (p≤0,05) compared with the control group in which osteopathic correction was not performed. The experimental group athletes had a significant decrease of the SD total number (p≤0,01) and the local somatic dysfunctions average number (p≤0,01). Functional test scores improved in both groups at the end of the study. However the functional tests indicators of the experimental group, in comparison with the control group, statistically significantly (p≤0,05) improved to a greater extent.Conclusion. The obtained data demonstrate the osteopathic correction positive effect on the practicing kendo athletes′ organism in the form of the somatic dysfunctions′ number decrease and the functional state improvement.

Peculiarities of Fencers’ Recovery in Pre-Сompetition Period When Using Foam Roller Massage

The purpose of this study was to evaluate the effects of foam rolling on delayed onset muscle soreness (DOMS) and the recovery of fencers’ technical and tactical qualities during a pre-competition period.&#x0D; Materials and methods. The study participants were male fencers (n = 12), SC “Unifeht”, aged 18.77 ± 2.55 years (6 – experimental group (EG), 6 – control group (CG)). The study lasted for two weeks of the pre-competition period. The CG fencers performed a self-myofascial release using a foam roller (BLACKROLL) for 20 minutes five times a week. The EG athletes were given partial restorative massage using a foam roller (10 + 10 minutes) five times a week. To assess the effectiveness of massage treatments, the study subjectively evaluated delayed onset muscle soreness, evaluated the impact of pain on daily life and changes in the parameters of the fencers’ technical and tactical qualities. The Spearman’s rank correlation coefficient (r) was used to roughly estimate the causal relationship between the existing factor and the emergence of the effect. The study compared original characteristics of the groups, using Mann-Whitney tests to compare the distribution of ordinal variables, Kruskal-Wallis and Wilcoxon tests (linked samples). A one-way repeated measures analysis of variance was carried out to estimate the impact of existing factors.&#x0D; Results. For two weeks of using a restorative massage and myofascial release, the study observed a significant increase in the parameters of the fencers’ technical and tactical qualities and a reduction in subjective pain in both groups (p &lt; 0.05). However, the EG athletes had a more positive subjective assessment of delayed onset muscle soreness at the time of survey than the CG members (0.2 ± 0.1 points in comparison with 1.5 ± 0.4; p &lt; 0.05) and a more significant reduction of the impact of pain on daily life (scales of walking ability, normal work at home and outside the home, sleep, p &lt; 0.05). At the same time, in two of the three tests that characterized the fencers’ technical and tactical qualities, the results were significantly higher in the EG (test exercise with thrust: 89.9 ± 2.8% in the CG in comparison with 98.6 ± 4.1% in the EG, and the test exercise with the coach’s occasional task: 88.2 ± 2.1% in the CG in comparison with 95.4 ± 3.8% in the EG, p &lt; 0.05).&#x0D; Conclusions. Massage treatments and self-myofascial release reduce the level of delayed onset muscle soreness, improve the recovery of technical and tactical qualities of fencers and reduce the impact of pain on daily life. The study has proved that foam rolling is effective in fencers’ recovery. This massage technique is relatively accessible, simple and it greatly facilitates a massage therapist’s work.

Effects of core strengthening on balance in university judo athletes

BackgroundCore strengthening prepares the body in an integral, safe and efficient way, favoring balance and postural control; physical abilities constantly demanded in sports, especially in body contact modalities, such as Judo. Objective: This study investigated the effects of core strengthening on balance in university judo athletes. MethodsEighteen athletes from the University of Southern Santa Catarina (UNISUL) were randomly allocated into two groups: experimental (n = 9) and control (n = 9). Experimental group athletes were submitted to a core strengthening protocol (30-min sessions, twice a week for 5 consecutive weeks). Evaluations consisted of Stabilometic (center of pressure behavior parameters: total area in mm2, laterolateral and anteroposterior width in mm) and baropodometric analysis [peak pressure: obtained during a 30-s acquisition period and expressed by foot area, i.e., (a) forefoot (metatarsal heads and toes); and (b) hindfoot (calcaneus region, distal third of the foot)]. Right/left foot ratios were calculated as relative percentages and used for the analysis. The analyzes were performed at baseline and after 5 weeks of core strengthening. The athletes were evaluated in two situations: eyes-open and eyes-closed. ResultsTotal right/left foot ratio pressure, right/left fore and hindfoot ratio pressure, as well as anteroposterior width measurements were statistically smaller in the experimental group. ConclusionAlthough the results obtained showed that core strengthening presents certain benefits, these data alone are not enough to confirm its effects upon postural oscillation in university judo athletes.

THE EXAMINATION OF THE EFFECTS OF FUNCTIONAL TRAINING PROGRAM APPLIED ON INSTABLE GROUND ON ANAEROBIC CAPACITIES OF ELITE MARTIAL ARTS ATHLETES

The aim of this study is to measure both dynamic balance of elite martial arts athletes doing functional strength exercises on instable ground and the effects of circuit training program on their anaerobic capacities, and compare them with those following classical training program. Students studying in Faculty of Sport Sciences at Duzce University and doing martial arts (kick box and muay-thai) constituted the study group. In the study conducted in 6 weeks with 24 sessions, while experimental group (EG) included 14 individuals (age: 19.78±1.36, height: 1.68±0.06) control group (CG) included 14 individuals (age: 19.92±2.09, height: 1.67±0.07) similar to those in experimental group. While athletes in EG followed circuit training program including strength exercises on instable ground in 6 weeks with 24 sessions, those in CG followed classical training program. Pre and posttests were applied before and after 6-week training program. First of all, height, weight and bioelectric impedance method was used for body fat rate, RAST test was done to measure agility by using electronic chronometer system with two-gated photocell having measurement in the sensitivity of 0.01, y-balance test battery was used to measure dynamic balance. Data was analyzed with SPSS 18. Collected data, pretest and posttest values of study and control group was analyzed with Wilcoxon test which was in 95 reliability range an significance level was accepted as p<0.05. When statistical data was examined, it was found that study group reported significant increments than control group in terms of anaerobic capacity, minimum power output, fatigue index, average power output and dynamic balance (p<0.05), while no significant differences were found in terms of other variables. Consequently, it was observed that exercises on instable ground developed dynamic balances of athletes. It is thought that athletes use required muscle function for balance during movement in the lowest level and this retards fatigue by effecting power output positively. Article visualizations:

The objective is to improve powerlifters’ technical preparedness at the initial training stage using a device for remote control of the competitive exercises technique.&#x0D; Materials and methods. The study relied on the following methods used: theoretical analysis and collation of data of scientific and methodological literature and internet; pedagogical observation; pedagogical experiment; methods of mathematical statistics.&#x0D; Results. We have designed an algorithmic structure for teaching squats with a barbell on shoulders in powerlifting and a device for remote control of the competitive exercises technique. We used the pedagogical experiment and pedagogical observation of the competitive activity to reveal reliable deviations (p &gt; 0.05) in the number of mistakes made by the athletes of the reference and experimental groups during the competitive activity. The reference group powerlifters made the mistake “no straight angle between the knee and the hip joints when performing the third stage” twelve times, while the experimental group athletes — seven times.&#x0D; Conclusions. The results obtained allow to maintain that the experimental group athletes have more rationally mastered the competitive exercises technique and made fewer mistakes compared to the control group powerlifters. This confirms the effectiveness of the designed algorithmic structure for teaching squats with a barbell on shoulders.

Influence of Whey Protein Drinks to Athletes: Taking Track and Field Athletes as Research Objects

According to the nutritional requirement of athletes during exercise, this study aims to invent a drink which mainly contains whey protein and is also added with saccharides and electrolyte, etc., to keep athletes’ athletic ability and accelerate the recovery of physical ability. Athletes that were going to participate in a track and field sports meeting of province were asked to drink the whey protein drinks during training and the index of Red Blood Cell (RBC), Hemoglobin (HB) concentration, Hematocrit (HCT), Mean Corpuscular Volume (MCV) of athletes’ blood were measured. The blood sugar concentration of athletes in control group before and after the experiment was 4.06±0.55 and 3.25±0.58 mmol/L, respectively, which lowered about 17% (p＜0.05) and the difference was statistically significant. However, the blood sugar concentration of athletes in experimental group before and after the experiment was 4.34±0.65 and 4.56±0.52 mmol/L respectively, which increased about 3.5% (p＜0.05) and the difference had no statistical significance. The experimental results showed that whey protein drinks could effectively protect body’s erythrocyte function, prevent decline of HB as well as strengthen physical ability, relieve fatigue and maintain the muscle microstructure. Therefore, whey protein drinks can effectively strengthen athletes’ immunocompetence as well as the muscle strength and it is also antioxidative and can prevent body damage and relieve fatigue. What’s more, whey protein’s various sports nutritional properties enable it to be widely applied to sports nutrition.

Dynamic Compression Enhances Pressure-to-Pain Threshold in Elite Athlete Recovery

Athlete recovery-adaptation is crucial to the progress and performance of highly trained athletes. The purpose of this study was to assess peristaltic pulse dynamic compression (PPDC) in reducing short-term pressure-to-pain threshold (PPT) among Olympic Training Center athletes after morning training. Muscular tenderness and stiffness are common symptoms of fatigue and exercise-induced muscle microtrauma and edema. Twenty-four highly trained athletes (men = 12 and women = 12) volunteered to participate in this study. The athletes were randomly assigned to experimental (n = 12) and control (n = 12) groups. Pressure-to-pain threshold measurements were conducted with a manual algometer on 3 lower extremity muscles. Experimental group athletes underwent PPDC on both legs through computer-controlled circumferential inflated leggings that used a peristaltic-like pressure pattern from feet to groin. Pressures in each cell were set to factory defaults. Treatment time was 15 minutes. The control group performed the same procedures except that the inflation pump to the leggings was off. The experimental timeline included a morning training session, followed by a PPT pretest, treatment application (PPDC or control), an immediate post-test (PPT), and a delayed post-test (PPT) after the afternoon practice session. Difference score results showed that the experimental group's PPT threshold improved after PPDC treatment immediately and persisted the remainder of the day after afternoon practice. The control group showed no statistical change. We conclude that PPDC is a promising means of accelerating and enhancing recovery after the normal aggressive training that occurs in Olympic and aspiring Olympic athletes.
