Optimizing training of students in gymnastic exercises in groups for improving sports skills

The article describes sports gymnastics as a leading means of physical education of student youth, which includes many different exercises, each of which consists of hundreds of movements in form and content. Modern sports gymnastics includes exercises with a complex coordination structure of movements, the athlete has to repeat the exercises many times, perform them intensively, often in conditions of fear of performing a complex exercise, which leads to various negative consequences in the conditions of educational and training classes. It is noted that the teaching of gymnastic exercises is based on the practical use of content and operational knowledge, on general didactic principles of the formation of movement skills and abilities. The special abilities that students should have in the process of learning gymnastic exercises are substantiated: coordination of movements, muscle strength, flexibility, speed of motor actions, speed and strength endurance, orientation in space, attention, memory of movements, emotional stability, determination and courage. The stages of the process of learning gymnastic exercises are highlighted: the formation of ideas about the exercise; unlearning the initial exercise to the level of motor skills; consolidating and improving a previously learned exercise to the level of a motor skill.

Competitive Neutrality: OECD Recommendations and the Australian Experience

Abstract The OECD in May 2021 adopted a recommendation that governments “ensure competitive neutrality to the maximum extent practicable and unless overriding Public Policy Objectives require otherwise.” This article discusses practical issues surrounding the formal implementation of competitive neutrality in a jurisdiction, using the well-established Australian framework as an exemplar. It illustrates the strengths and weaknesses of the Australian system and provides guidance to other jurisdictions in formulating their approaches to implementing the Recommendation. It demonstrates that implementation of competitive neutrality at a practical level is a complex exercise, which demands both strategic vision and detailed planning.

Sources of Information That Guide the Pedagogical Work of Early Childhood Educators: An Exploratory Study in Chile

The following article is a qualitative study that identifies the types of sources accessed by early childhood educators in their search for information to guide their pedagogical decisions regarding classroom problems. Previous study was centered on the understanding that teaching is a demanding and complex exercise, exposed to multiple problems, where the sources of information used by the educators can be a way to understand the ways in which they inform themselves when facing unexpected problems. The research is based on the interpretative-comprehensive paradigm, with a qualitative methodology, which included 22 semi-structured interviews with practicing kindergarten educators, with a minimum of one year of experience in the Maule Region, Chile. The findings of the study indicate that non-written sources such as other professionals, colleagues and family were the most reported by the participants as sources of information to help them understand their classroom problems, emphasizing that the relationship with others is fundamental, highlighting the importance of interdisciplinary work and recognizing their professional limits.

Guidelines for genetic data analysis

The IWC Scientific Committee recently adopted guidelines for quality control of DNA data. Once data have been collected, the next step is to analyse the data and make inferences that are useful for addressing practical problems in conservation and management of cetaceans. This is a complex exercise, as numerous analyses are possible and users have a wide range of choices of software programs for implementing the analyses. This paper reviews the underlying issues, illustrates application of different types of genetic data analysis to two complex management problems (involving common minke whales and humpback whales), and concludes with a number of recommendations for best practices in the analysis of population genetic data. An extensive Appendix provides a detailed review and critique of most types of analyses that are used with population genetic data for cetaceans.

Types and kinds of etymological exercises in Russian vocabulary

This paper considers educational and school etymological analysis (etymological parsing) as a type of Russian language exercises. The objective that was set and achieved involved developing a typology (a classification) of etymological exercises corresponding to the main subject competences. Based on the ‘presence/absence of reference supports’ ctiterion, we classify etymological exercises into those performed a) with and b) without reference supports, i. e. from memory and intuition. Known and new etymological exercises are divided into three types, namely speech, language, and complex. Speech (textual) tasks split into two types: perception and reproduction of ready-made etymological messages and preparation of new etymological messages using one or several reference supports. Language exercises include classical and game-based vocabulary exercises with partial etymological analysis. Complex exercises are treated as a complete structural analysis (morphemic, derivational) with an etymological follow-up. The essence of the etymological tasks is revealed through typical didactic material, assignments, and sample works. The taxonomic and entity description of etymological exercises creates prerequisites for their continuous and sys- tematic use in teaching Russian in all comprehensive school forms.

Self-directed kinematic adjustments when learning the kettlebell swing in young adults

ABSTRACT The kettlebell swing is a complex exercise shown to provide cardiovascular and strength benefits. However, novice kinematic pattern differences might limit the effectiveness of the kettlebell swing to fully realise those benefits. The purpose of this study was to assess how novices self-directed their learning of the kettlebell swing using only an instructional video. Twelve young adults performed kettlebell swings sets over one week. We captured kinematic data of their first sets without practice, sets within-day following practice, and sets one week later following practice. The subjects received no augmented feedback. Ankle, knee, hip, and shoulder mean and variability kinematics were compared. In addition, the relative timing of peak sagittal plane angular velocity of the hip and shoulder was evaluated to determine whether the hips led to the shoulders. Within-day subjects reduced hip and shoulder peak extension, knee and hip peak flexion, and hip peak flexion velocity. Between-day subjects reduced mean hip peak flexion and range of motion, as well as peak knee flexion. Our results suggest novices prioritised improving consistency early in practice and then adjusted their kinematic pattern over the week. Moreover, most subjects transitioned to the hips leading shoulders, suggesting this is a perceivable coordination pattern by intrinsic feedback.

A post-exercise infrared sauna session improves recovery of neuromuscular performance and muscle soreness after resistance exercise training.

The aim of this study was to investigate effects of a single infrared sauna (IRS) session on post-exercise recovery of neuromuscular performance, autonomic nervous system function, subjective sleep quality, and muscle soreness. Male basketball players (n = 16) performed two trials consisting of a complex resistance exercise protocol (maximal strength with plyometrics), followed by either 20 min passive recovery (PAS) or IRS (temperature 43 ± 5°C), in a randomized crossover design, with trials separated by one week. Recovery of neuromuscular performance was assessed using 20 m maximal sprint, maximal countermovement-jump (CMJ), and isometric leg press tests, performed 14 hours after exercise. Heart rate (HR), heart rate variability (HRV), sleep diary, muscle soreness, and indirect muscle damage markers were measured pre and post exercise. The decrease in CMJ performance from pre- to post-exercise was attenuated after IRS compared to PAS (p < 0.01). The IRS session resulted in higher HR and lower root mean square of successive differences between normal heartbeats (RMSSD), and high and low frequency power, compared to PAS (p < 0.002). Post-exercise night-time HR and HRV did not differ following IRS vs. PAS. Muscle soreness was less severe, and perceived recovery was higher after IRS compared to PAS (p < 0.01). Post-exercise IRS attenuated the drop in explosive performance and decreased subjective muscle soreness after resistance training, which may enhance mood, readiness, and physical performance of an athlete. A single IRS session had no detrimental effects on recovery of the autonomic nervous system.

코로나 시대의 비대면 복합운동이 여중생의 신체조성, 성장호르몬 및 세로토닌에 미치는 영향

The purpose of this study is to investigate the effect of non-face-to-face complex exercise programs on female middle school students" body composition, growth hormone, and serotonin. A total of 20 middle school girls were classified into exercise groups (10 people) and control groups (10 people), and exercise was conducted three times a week for 12 weeks for 50 minutes, 50-60% HRR (RPE11-13) for 1-6 weeks, and 60-70% HRR (RPE13-15) for 7-12 weeks. The measurement was performed twice in advance and after, and the mean value (M) and standard deviation (SD) were calculated, and the paired t-test was performed for the pre and post differences and the independent t-test for the differences between groups. The interaction effect between groups and periods was repeated measure ANOVA, and the statistical significance level was set to (α)=.05. As a result, interaction effects were found in %BF, SMM, and GH of the exercise group. It is thought that students who lacked physical activity reduced body fat through continuous complex exercise, and positive physical changes in growth hormone and serotonin were shown through repeated physical movements. Accordingly, it is believed that non-face-to-face complex exercise had a positive effect on female middle school students" body composition, growth hormone, and serotonin.

Developing a framework for open and FAIR data management practices for next generation risk- and benefit assessment of fish and seafood.

Risk and risk-benefit assessments of food are complex exercises, in which access to and use of several disconnected individual stand-alone databases is required to obtain hazard and exposure information. Data obtained from such databases ideally should be in line with the FAIR principles, i.e. the data must be Findable, Accessible, Interoperable and Reusable. However, often cases are encountered when one or more of these principles are not followed. In this project, we set out to assess if existing commonly used databases in risk assessment are in line with the FAIR principles. We also investigated how access, interoperability and reusability of data could be improved. We used the OpenFoodTox and the Seafood database as examples and showed how commonly used freely available open-source tools and repositories can be implemented in the data extraction process of risk assessments to increase data reusability and crosstalk across different databases.

The Effect of 6-Month Complex Exercise on Serum Bone Metabolism: Focused on the Elderly over 75 Years Old

Korea already entered the aging society (August 2017), in which 14% of the population is 65 years or older, and it is expected to enter as a super-aged society, in which 20% of the population is elderly at the world’s fastest rate by 2025. This means that a health management plan is needed to effectively manage the health of the elderly in preparation for the upcoming super-aging society. Therefore, this study analyzed the effects of exercise on serum osteocalcin, bone ALP, and estradiol, which are representative indicators of bone formation after six months of complex exercise, and confirmed the usefulness of exercise programs and biochemical indicators for the elderly in late years to provide basic data for the prevention of osteoporosis. The subjects of this study were the elderly in late years (exercise group = 14, control group = 15), those 75 years or older in Korea, who performed complex exercises twice a week for six months. As a result of analyzing the effect of exercise performance on osteocalcin in the elderly in late years for six months in this study, no significant difference was found. However, osteocalcin decreased by 7.7% in the control group and increased by 18.66% in the exercise group, while ALP increased by 18.92% in the control group and significantly increased by 69.81% in the exercise group. As a result of analyzing the effect on estradiol, there was no significant difference, but it decreased by 55.09% in the control group and decreased by 1.85% in the exercise group. Based on the results showing that exercise clearly plays a positive role in improving bone density even for middle- and late-aged elderly people, in the future, the exercise will be useful to maintain and improve health related to the skeleton of the elderly through the combined participation of aerobic, resistance, and balance exercises. In addition, it is necessary to conduct repeated studies targeting the elderly of various age groups to evaluate the effects of exercise according to period and gender.

It is necessary to focus on training those abilities and using auxiliary training methods in exercises that simulate individual or group offensive performance with the cooperation of two or three players among basketball players for the junior category, as it is the reliable category in the future as the bond and the main pillar of the national teams, so attention must be paid to this age group by preparing Complex exercises linking the physical and skill side to advance the level of Iraqi basketball, as its development in the early stages of life through general physical exercises leads to reaching a high level of performance ability. The first is to enrich scientific research in the sports field by providing new knowledge information that can be used, and the second is that the data that the researcher will obtain through her study will be an important reference for many researchers and trainers to benefit from.

Evaluating behavior change factors over time for a simple vs. complex health behavior.

BackgroundResearchers are working to identify dynamic factors involved in the shift from behavioral initiation to maintenance—factors which may depend on behavioral complexity. We test hypotheses regarding changes in factors involved in behavioral initiation and maintenance and their relationships to behavioral frequency over time, for a simple (taking a supplement) vs. complex (exercise) behavior.MethodsData are secondary analyses from a larger RCT, in which young adult women, new to both behaviors, were randomly assigned to take daily calcium (N = 161) or to go for a daily, brisk walk (N = 171), for 4-weeks. Factors (intentions, self-efficacy, intrinsic motivation, self-identity, habit strength) were measured weekly. Multi-level modeling evaluated their change over time. Bivariate correlations and multiple regression determined the relationships between factors and the subsequent-week behavioral frequency (self-report and objective).FindingResults were partly in-line with expectations, in that individuals’ intentions and self-efficacy predicted initial behavioral engagement for both behaviors, and habit strength increased for both behaviors, becoming a significant predictor of behavioral frequency in later weeks of the study in some analyses. However, results depended on whether the outcome was self-reported or objectively measured and whether analyses were bivariate or multivariate (regression).DiscussionThe factors theorized to play a role in behavioral maintenance (intrinsic motivation, self-identity, and habit strength) started to develop, but only habit strength predicted behavioral frequency by study-end, for both behaviors. Differences in initiation and maintenance between behaviors of differing complexity may not be as stark as theorized, but longer follow-up times are required to evaluate maintenance factors.
