Basic Swimming Style Crawl Engineering Skills Survey in Athletes Ages 10-12

This study aims to: 1.To know the basic technique skills of crawl style swimming in the Kebumen swimming club association students. 2. Knowing the factors of difficulty experienced by students in learning the basic motion skills of crawl style swimming 3. Students are able to apply the basic movements of swimming with the right steps. This research was conducted on the students of the Kebumen swimming club association in Gossi Kebumen. The research plan is carried out in November 2021. The sample referred to in this study is 20 students in the 10-12 year age group who take part in basic swimming skills training. Descriptive data analysis was entered to get an overview of the data including the average, standard deviation, maximum data, minimum data, range, frequency table and graphs. Based on the results of the research that has been carried out, it can be concluded: 1. Freestyle swimming skills measured using a stopwatch on students aged 10-12 years at the swimming club association in Kebumen showed that 50% of students had very poor swimming skills, 25% students have poor swimming skills and 25% of students have sufficient skills. 2. The category of skills that dominates the most in students is very low ability. Contributing to further research is to conduct research on more intense exercises on crawl swimming style techniques need to be done by athletes and also strategies to improve the ability of athletes in crawl style swimming.Keywords: Swimming, Crawl Style, Basic Swimming Technique

Selection of the Best Swimming Athletes using MCDM-AHP and VIKOR Methods

The process of selecting the best swimming athletes is carried out in several test stages, the first is the ability in the four basic swimming styles which often contested in international competitions and the second test is the basic physical abilities possessed by a number of swimming athletes. The tests related to the swimming style consist of breaststroke swimming, butterfly swimming, backstroke swimming and crawlstroke swimming, while the plyometrics test consists of banded knee jump, squat jump, jump to side, and dept jump, Due to the large number of selections, a test is required for every athlete. The purpose of this selection is to find the best swimming athletes who will be competed in the international swimming class event. The nine athletes of millenium aquatic swimming club that were selected previously, they are the forerunners of the selected swimming athletes and will be evaluated on a representative basis, which is the best among the nine athletes. The method used in the evaluation and selection process uses two continuous methods, namely the AHP and VIKOR methods. From the results selection assessment, it was found that the best three of the nine nominations selected, the first position selected was AT2 with an index 0.00, the second position was AT8 with an index 0.25 and the third position was AT7 with an index 0.61. Thus it can be concluded that the AHP and VIKOR methods can be used as decision support to determine optimally in the optimal selection process for swimming athletes.

The Effect of The Numbered Head Together Learning Model on Student Achievement in Science Subjects Style Class IV SDN 3 Sukamanah

Science learning must be interpreted as an activity that is observational, experimental and predictive, so that students can understand science concepts appropriately and can be verified. In science learning in grade IV SDN 3 Sukamanah there are several obstacles in learning style material, namely the lack of supporting facilities when science subjects take place such as learning media and practical tools, style material for fourth grade students is still unfamiliar / new to learn like the style what the student means is the selfie or swimming style so that the teacher also requires a lot of time and must prepare adequate support and the learning process carried out by the teacher only uses the lecture learning model, so that learning achievement in science subjects does not achieve the learning objectives which are expected. Based on these problems, the researchers applied the Numbered Head Together learning model to determine the effect on student achievement in science subjects class IV style material of SDN 3 Sukamanah. The research method used in this study is an experimental research method with a quasi-experimental design in the form of One-Group Pretest-Posttest. The research was conducted at SDN 3 Sukamanah with a population of sixteen people.

Impact of wellness swimming technique on women 40–50 years old with cardiovascular pathology

Currently, traditional and non-traditional means are widely used in recreational swimming. Traditional means of recreational swimming include all methods of sports and applied swimming. Unconventional forms of swimming classes include hydroaerobics (aquaerobics), hydroshaping, hydroprophylaxis, etc. Functional tasks (general strengthening effect, improvement of respiratory and circulatory function, strengthening of certain muscle groups, posture correction, etc.) determine the choice of swimming style or individual elements from the swimming style for recreational classes. In some cases, it is advisable to depart from the principles of sports swimming and combine different styles, for example, hands work as a breaststroke, and legs work as a front crowl. Combinations of movements from different swimming styles are easier for many people to coordinate, so they absorb them faster and easier in wellness swimming. Occupation of wellness swimming is recommended both for people who have deviations in their state of health, and simply for those who want to strengthen body and increase its functionality. A gradual increase in the load with a reasonable dosage of swimming exercises both on land and in water characterizes occupations of this type of swimming. Groups for classes are formed taking into account the age, gender, form and degree of disease, different levels of swimming fitness of those involved.

A small whale reveals diversity of the Eocene cetacean fauna of Antarctica

Cetacean fossils have been recorded from middle and late Eocene deposits on Seymour Island since the beginning of the twentieth century and include fully aquatic Basilosauridae and stem Neoceti. Here, we report a small cetacean vertebra tentatively referred to as Neoceti from the late Eocene of Seymour Island. It shows a mosaic of traits, some of which are characteristic of early Neoceti (anteroposteriorly long transverse processes; a ventral keel on the ventral side of the centrum; thin pedicles of the neural arch), whereas others are shared with Basilosauridae (low-placed bases of the transverse processes). However, some traits are unique and may be autapomorphic: presence of separate prezygapophyses on the vertebra at the thoracic/lumbar boundary and a proportionally short centrum. Both traits imply a fast swimming style, which is characteristic of modern dolphins rather than Eocene cetaceans. Thus, this specimen can be identified as Neoceti indet., with some hypothetical odontocete affinities. Along with a few other Eocene whale taxa, it seems to be among the earliest known members of Neoceti on Earth. The finding of small and fast-swimming Neoceti in Antarctica also demonstrates early diversification of cetaceans and ecological niche partitioning by them dating back as early as the late Eocene.

INVESTIGATION OF ANXIETY OF SWIMMERS REGARDING CONTRACTING NEW TYPE OF CORONAVIRUS (COVID-19)

Aim: In this study, it was aimed to investigate that anxiety of Swimmers about contracting new type of Coronavirus (Covid19). Method: Swimmers in active state in Turkish Swimming Federation participated in this study. The participants of this research consist of 247 female and 203 male swimmers (450 in total) who are in active state in Turkish Swimming Federation. In this study, “Personal Info Questionare” and “Anxiety of atheletes for contracting new type of Coronavirus (Covid-19) scale” developed by Demir et al. (2020) were used as data collection tool. Results: Differences between sex and personal anxiety sub-dimension and general differences were determined. Differences between in personal anxiety and anxiety regarding socializing both in sub-scale and overall were determined. There is no difference reported according to factors such as financial status based on minimum wage, having a chronic disease, the best swimming style, making practice at home during pandemic. Conclusion: It was concluded that, swimmers have higher level of anxiety of contracting new type of Coronavirus (Covid-19) than the medium level in this study.
