The objective of the study was to deal with the ratio of the parameters of maximum muscle power and power endurance and explain their contribution to the sports performance in kayak disciplines of Slovakia National Team members. Material and methods. Strength parameters were monitored by Tendo Power Analyser in the barbell bench press and pull on a horizontal bench. A diagnostic series of maximum power and effective repetition test for power endurance was performed at both, barbell bench press and bench pull exercises. Determining the factors limiting sports performance in kayak disciplines 200 meters, 500 meters, 1,000 meters, 5,000 meters, and marathon 21,500 meters, the evaluation of dependence between all power variables were used. The stepwise regression was used to reduce the indicators. Results. It was found out that in kayak sprint disciplines (200 meters, 500 meters) the sports performance in the kayak is influenced by the barbell bench pull more than bench press on the horizontal bench when speaking about the strength parameters. In the middle-distance disciplines (1,000 meters), the ratio of strength parameters is balanced. As the length of kayak disciplines increases (5,000 meters and 21,500 meters), the ratio of strength parameters has changed in favor of the barbell bench press. From the parameters of maximum muscle performance and muscle endurance measured in the barbell bench press and pull on a horizontal bench, the average power of power endurance was demonstrated to explain the sports performance in kayak disciplines. Conclusion. From the parameters of maximum power and power endurance in the bench press and bench pull in all kayak disciplines, the parameter of average power in power endurance was proved to explain sports performance. Knowledge of these factors will allow optimizing the content of sports training of kayakers, the process of developing their strength skills, and their transformation process into a structure of sports performance and kayaking paddling technique.

Aim: To study the peculiarity of electromyography signal characteristics alternation using different sEMG parameters during repetitive voluntary isometric fatiguing contraction in adolescent boys. Materials and methods. 12 subjects with height 148.75 ± 10 cm; Mass 38.9 ± 7.9 kg; age – 12 to 14 years were recruited. The sEMG signal alteration of external oblique, rectus abdominis, erector spinae muscles during a fatiguing plank were analyzed. A separate one-way repeated measures ANOVA was used to test the statistical significance of task time and electromyography parameters of the global core muscle in the pre-, during- and post-fatigue plank test. One-way Friedman ANOVA was applied for Shapiro-Wilk p < 0.05. The Pearson product-moment correlation coefficient with bivariate linear regressions analysis was performed between the pre-pre fatigue and post-post fatigue amplitude mean and standard deviation values. The Spearman correlation coefficient between amplitude and endurance time both in the pre- and post-fatigue state was conducted. Results. The mean value of rectified amplitude increased (p < 0.05) for all muscles, the standard deviation of amplitude and total spectral power increased significantly (p < 0.05) for all muscles except the erector spinae muscle (p > 0.05). The power at normalized low frequency significantly changed (p = 0.05) in the erector spinae muscle. A significant change in normalized low frequency for agonist/synergist (p = 0.02) and agonist/antagonist muscles (p = 0.05) was observed. The average amplitude value had a significant positive and linear relationship with the amplitude variability both in the pre- to post-fatigue state, except the erector spinae muscle. The time to task failure was not correlated (p > 0.05) with the sEMG amplitude. Conclusions. Increased sEMG amplitude resulted mainly from rapid additional motor unit recruitment and rate coding during muscle fatigue. The reduction of conduction velocity might affect the spectral power with a spectral shift towards low-frequency. Increased variability, agonist/antagonist co-activity during fatiguing contraction might extend the holding time. The postural fatiguing task/plank increases multiarticular joint function by involving several joints and muscles, increases variability in the contribution of synergist muscles. This factor provides an intuitive explanation about the absence of a relationship between endurance time and sEMG amplitude changes.

The study purpose was to follow a prospective cohort study design to use gait kinematic parameters to identify the risk factors and to develop a statistical model to predict running-related lower limb injuries of sportspersons. Materials and methods. BTS G-WALK® gait analysis system was used to collect gait kinematic data of 87 subjects from an institute of physical education and sports science. The subjects were followed for a full academic season after which the researcher inquired about their injury occurrences. Binary logistic regression was used to develop a prediction model to predict lower limb injuries of sportspersons. Results. The result of the study revealed that increasing Range of Obliquity, Range of Tilt and Range of Rotation were associated with increased likelihood of future running-related lower limb injury. However, the lower Symmetry Index was associated with increase in the likelihood of future running-related lower limb injury. Conclusions. The study confirmed that it is possible to predict injury, but for practical implication further research is essential with a bigger sample size.

The purpose of the study was to identify gender-related peculiarities of 7-year-old schoolchildren’s motor fitness. Materials and methods. The study participants were 59 7-year-old schoolchildren (girls – 27, boys – 32). The children and their parents were informed about all the features of the study and gave their consent to participate in the experiment. The study used the following research methods: analysis of scientific and methodological literature, pedagogical observations, testing of motor fitness, probabilistic approach to assessing the learning process, methods of mathematical statistics. The study recorded the primary schoolchildren’s level of proficiency in gymnastic exercises. The coefficient was determined by the formula: p = (m/n)×100, where p is the level of proficiency, m is the number of successfully performed exercises, n is the total number of attempts to perform the exercise. In the experiment, the study controlled the level of proficiency in the following exercises: forward roll; backward roll; shoulderstand with bent legs. Results. The differences in the development level of movement coordination of individual parts of the body and vestibular stability are not statistically significant; in the 7-year-old girls and boys, there is a statistically significant difference in the development level of strength, speed strength, speed, endurance, and the level of proficiency in acrobatic exercises. Conclusions. A canonical discriminant function can be used to classify and identify the indicators that have the greatest weight in assessing gender-related peculiarities of 7-year-old schoolchildren’s motor fitness. In assessing gender-related peculiarities of 7-year-old schoolchildren’s motor fitness, these indicators include the level of proficiency in acrobatic exercises, the level of relative strength of shoulder flexors, endurance, and speed strength.

The objective of the study was to determine the age-related peculiarities of functional and motor fitness of students of a special medical department of higher education institutions. Material and methods. The study participants were 1st year (n = 34); 2nd year (n = 14); 3rd year (n = 58); 4th year (n = 21); 5th year (n = 16) male students. One group was organized in each year of study, which added up to five experimental groups. All the students participated in physical education classes twice a week. To solve the tasks set, the following research methods were used: analysis of scientific literature, pedagogical observation, pedagogical testing, formative experiment, index method, biomedical methods, and methods of mathematical statistics. During classes, the study used the method of strictly regulated exercise (motor density of the class was 50-70%), for developing general endurance – the continuous method with covering a distance of 1,000-2,000 m (heart rate: 120-150 beats per minute), circuit and repetition methods. Results. The study results show positive changes in the functional state of the respiratory system and speed and strength abilities in the 1st-5th year students of the special medical department (p < 0.05). Conclusions. A successful development of the basic functional body systems and motor abilities in 1st-5th year students can be achieved under the influence of pedagogical conditions, namely: the method of strictly regulated exercise using exercise equipment (motor density of the class was 50-70%); the continuous method with covering a distance of 1,000-2,000 m at a slow pace (heart rate: 120-150 beats per minute); circuit and repetition methods. By the results of comparative analysis of the functional and motor fitness, the 1st-5th year male students of the special medical department show better results in tests for assessing the cardiovascular and respiratory systems, speed and strength abilities. In the 18-22 age range, according to the Ruffier index, there is an increase in the number of male students of the special medical department with a “good” and “satisfactory” cardiovascular system state and a decrease in the number of students with a “bad” result.

The objective of the study was to substantiate the influence of selected independent variables for building optimal models of teaching a series of tasks aimed at motor skills development in boys aged 10. Materials and methods. The study involved 32 boys aged 10. The children and their parents were informed about all the features of the study and gave their consent to participate in the experiment. To achieve the objective set, the following research methods were used: study and analysis of scientific and methodological literature; pedagogical observation, timing of learning tasks; pedagogical experiment, methods of mathematical statistics, methods of mathematical experiment planning. In the process of teaching, a method of algorithmic instructions was used. Results. The effect size of the factor varied from series to series. The calculated Cochran's criterion showed that all the groups of experimental data were obtained from the same population. It was found that the variances do not differ for the selected significance level of 0.05. Each independent variable (X1, X2, X1X2) plays a role in changing the indicator of proficiency in the Mawashi-geri-jodan (roundhouse kick). The constructed mathematical models adequately describe the obtained data. The calculated regression coefficients are statistically significant (Fр < Fkр), which means that the regression model is effective. Throughout the experiment, the independent variable Х1 “number of sets” had a constant positive effect on the target feature (Y). The percentage contribution in the first series of learning tasks was 59.3%, in the second – 88.6%, in the third – 56%, in the fourth – 93.9%, in the fifth – 81.3%, in the sixth – 69.62%. The independent variable Х2 “rest interval” has a negative effect in the first series – 25.9%, in the second series – 10.6%, in the fifth – 9.9%, in the sixth – 13.1%. A positive effect of the first-order interaction (X1X2) was observed in the third series – 29.1%, the fifth – 8.9%, the sixth – 17.28%. Conclusions. The optimal combinations of conditions for the series of tasks when teaching boys aged 10 the Mawashi-geri-jodan (roundhouse kick) are the following: series 1 – 3 sets, rest interval 60 s; series 2 – 3 sets, rest interval 60 s; series 3 – 3 sets, rest interval 120 s; series 4 – 3 sets, rest interval 60–120 s; series 5 – 3 sets, rest interval 120 s; series 6 – 3 sets, rest interval 120 s.

The purpose of this study was to evaluate the effectiveness of a combined exercise program focused on the improvement of young women’s physical condition. Materials and methods. The study involved 62 healthy women (an average age of 29.4 years). More than 50 parameters were assessed (anthropometric indicators, physical capacity and motor abilities, functional status of the cardiorespiratory system, etc.). The structure of physical condition of the women was identified using the factor analysis. The transforming experiment lasted for 14 months. Results. The physical development indicators had the largest contribution (33.4%) to the total variance of physical characteristics of the subjects. The second factor related to the functional state and physical performance accounted for 21.6%, the third factor related to coordination abilities accounted for 19.8%, and the fourth factor related to physical fitness accounted for 10.3% of the total variance. Those four factors explained 85.1% of the total variance. The 35 indicators, which were selected by the factor analysis and characterized the women’s physical condition, were used as criteria for the effectiveness of the proposed exercise program. Participation in the exercise program significantly affected the morphological status of women. Functional indicators of the cardiovascular system improved significantly, including resting heart rate decreased by 16.2% (p < 0.05). Muscle strength increased by 32.2% (p < 0.05), speed and strength endurance and speed endurance increased by 31.5% and 49.1%, respectively (p < 0.05). Exercises targeting coordination abilities lead to improvements in balance ability of women as assessed by the Romberg test (increase by 94.0%, p < 0.05) and by the Flamingo test (increase by 65.6%, p < 0.05). Conclusions. The study confirmed the effectiveness of the combined exercise program according to selected criteria. There were significant (p < 0.05) positive changes in physical condition components including physical development, physical fitness, functional state of the cardiorespiratory system and in body balance.

The 35 indicators, which were selected by the factor analysis and characterized the women’s physical condition, were used as criteria for the effectiveness of the proposed exercise program. Participation in the exercise program significantly affected the morphological status of women. Functional indicators of the cardiovascular system improved significantly, including resting heart rate decreased by 16.2% (p < 0.05). Muscle strength increased by 32.2% (p < 0.05), speed and strength endurance and speed endurance increased by 31.5% and 49.1%, respectively (p < 0.05). Exercises targeting coordination abilities lead to improvements in balance ability of women as assessed by the Romberg test (increase by 94.0%, p < 0.05) and by the Flamingo test (increase by 65.6%, p < 0.05). Conclusions. The study confirmed the effectiveness of the combined exercise program according to selected criteria. There were significant (p < 0.05) positive changes in physical condition components including physical development, physical fitness, functional state of the cardiorespiratory system and in body balance.","PeriodicalId":36640,"journal":{"name":"Teoria ta Metodika Fizicnogo Vihovanna","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67692434","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
The purpose of this study was to find the effects of a 12 weeks IAAF Kid’s Athletics programme on the psychological and motor fitness abilities of sedentary school-going children. Materials and methods. The study involved 40 students (age 10 to 14 years) with no previous history of systematic training. The subjects were further sub-divided based on their age, i.e. low age (10 to 11 years) and high age (13 to 14 years), and then randomly assigned to either an experimental group (Kid’s Athletics) or a control group. The psychological variables selected were stress tolerance reactive, simple motor speed, simple reaction speed, visual perception, and focused attention, whereas motor variables selected were sit and reach test, standing broad jump, 50m sprint, T-test, and 150m sprint. Tests were conducted pre-training, mid-training, and post-training for motor variables while only pre-training and post-training tests were conducted for psychological variables. Results. The two-way mixed ANOVA revealed a significant difference in all the selected variables (motor and psychological variables) in group × time interaction (p = 0.001 to <0.001) with large effect sizes. Lager effect sizes in motor fitness variables were observed after 12 weeks (ES = 2.09 to 5.72) than 6 weeks (ES = 1.92 to 3.47) when compared to baseline in the experimental group. Conclusion. The study shows that Kid’s Athletics recommended by IAAF may be considered as an effective programme to improve psychological as well as motor abilities in sedentary school-going children.

The aim of this study was to investigate the influence of body composition on the anaerobic strength of the lower extremities, as well as the prediction of body composition on the results of anaerobic ability in professional football players. Materials and Method. The sample of respondents consists of female football players who compete in the highest rank of the competition, the Serbian Super League. The total number of respondents included in the study was 21 female football players (age 19.38 ± 3.69, body height 166.48 ± 6.17 cm, body weight 59.98 ± 7.09 kg). The study is of a transversal nature and testing was done in the pre-competition period. The sample of measuring instruments used in the research are body composition and assessment of anaerobic strength of the lower extremities. Assessment of body composition was performed indoors using a multifrequency bioelectric impedance (Inbody 770). Variables for estimating the anaerobic strength of the lower extremities were obtained using a bicycle ergometer (Monark 839E) in the Wingate Anaerobic Test. Results. The results of body composition show a statistically significant influence on the prediction of maximum anaerobic strength of the lower extremities in professional female football players (p < 0.05), as well as on the overall work in the anaerobic zone and the mean values of anaerobic strength. Regression analysis of the influence of body composition on the parameters of maximum strength in (W/kg) and fatigue rate does not show statistically significant results. Conclusion. There is a statistically significant influence of body composition, such as: body weight, lean body mass (%), muscle mass in absolute and relative values, on the values of maximum anaerobic strength, mean values of anaerobic strength and overall work in professional female footballers.

The purpose of the study was to obtain regression models of immediate and delayed training effect of strength loads in boys aged 8 years, based on a full factorial experiment. Materials and methods. The study participants were 48 boys aged 8 years. The experiment was performed using a 22 factorial design. The study materials were processed by the IBM SPSS 22 statistical analysis program. The study examined the impact of four variants of strength load on the immediate (ITE) and the delayed (DTE) training effect of orthogonal strength exercises modes and rest intervals in boys aged 8 years. Results. The study results show that in the proposed matrix of the 22 full factorial design, the chosen step of variation of factors is sufficient to study the influence of different modes of strength exercises on the dynamics of ITE in boys aged 8 years. Based on the data analysis, the study obtained regression models of load for calculating the ITE1, ITE2, and DTE. The obtained regression models make it possible to calculate the number of repetitions and rest interval to achieve the most rational load variant. Conclusions. The analysis of regression equations shows the interrelation between training effects: ITE1 —> ITE2 —> DTE. The value of ITE1, ITE2, and DTE at station I (exercises to strengthen arms and shoulders) and station II (exercises to strengthen abdominal muscles) depends on the increase in the number of repetitions in a set and the duration of the rest interval. The value of ITE1, ITE2 at station ІІІ (exercises to strengthen back muscles) depends on the increase in the number of repetitions in a set and the duration of the rest interval. The value of DTE – on the increase in the number of repetitions in a set and the reduction of the rest interval duration. The value of ITE1 at station IV (exercises to strengthen leg muscles) depends on the increase in the number of repetitions in a set and the reduction of the rest interval duration. To strengthen the DTE, it is necessary to reduce the number of repetitions in a set and the duration of the rest interval.
