The kinematic analysis of the Russian wendeswing technique performance in different types of supporting surfaces was undertaken using the 3D Qualisys motion capture system. A high-level qualified gymnast performed 5 routines of three Russian circles on the floor and same on pommel horse. The average performance time of Russian circle on the floor was about 0.3 s less than the same skill performance time on pommel horse. The phase structure of each circle contained 4 hand steps of 0.3-0.4 s duration each. Russian circles control actions are performed through the arms. On floor there was a change of the shoulder joint angle in the range of 4° to 35°, whereas on pommel horse, the performance showed the shoulder joint angle range of 9° to 40°. In our research, the main difference between Russian circles performed on different apparatus was found in the positions and shifting of hip joints and the sacrum attached markers. On floor, the Russian circle performance showed a shift in the vertical sacrum marker in the range of 19 cm compared with 11 cm on pommel horse. The results indicated that floor circles demand higher rotation speed from the athlete and presumes bigger vertical hips shifting. On pommel horse, Russian circles performance registered a lower range of angular velocity and vertical hip shifting but had greater shoulder joint angle.

In modern conditions, no one doubts that physical culture and sports are useful and necessary for every person. A team of SPbPU authors have developed and introduced into the educational process of MOOC courses "Physical culture" in 2016, "Fundamentals of the training process of cybersports men" in 2020, posted on the National portal "Open Education". The Physical Education online course can be one example of organizing such resources. Today (and especially during a pandemic) this is one of the most popular courses with a massive audience. At the Polytechnic University, it is involved in all curricula and is compulsory for all students. Our research is devoted to further prospects for the development of the resource. Of course, it is very difficult to define the concept of "pedagogical skill" in the context of this article. However, we tried to do this, highlighting the main, from our point of view, the criteria of pedagogical excellence, which are necessary for the high-quality implementation of courses in a distance format. The online resources we have created allow us to stimulate and motivate students for personal development, organize their educational activities, including building a training system, organize pedagogical activities, monitor the success of students' development of resources, and structure classes. The implemented system made it possible to organize training during the COVID-19 pandemic without interruptions and without reducing the quality of education.

Curling is a team sports game played on ice. The athletes slide stones one by one toward a marked target area. This is a sport in which the exactness of a throw is the base of technique and one of the main components of a successful play. In sport, technique means the way of making a physical action. Technical preparation is a process of education and improvement of movement skills, serving a mean of sports fighting. For making a throw of a curling stone an athlete has to push himself off a hack and slide in a deep lunge position holding a stone in his hand. In front of the hog line an athlete releases the stone. This paper describes the machines for training the technique of throwing a curling stone. Using empirical research methods we have created and used the machines which were used during the training process at the special preparation stage of the preparation period. A special training roller ground for throwing curling stones was developed. The useful model RU 192760 patent was published on September 30, 2019. The developed equipment allows to do imitative training of movements and technique of curling stones throwing. A training roller ground for a curling player’s boot was designed. The useful model RU 193702 patent was published on November 11, 2019. The conditions for simulating training of exactness of take-off force in curling were created

This project aimed to identify if there were differences in coaching behaviours between coaches trained and educated in less-academic, traditional, governing body of sport approaches (n=6) and those who were educated and trained through Higher Education routes (n=6). Data were gathered from twelve coaches by videoing and audio-recording coaching sessions. The data were analysed using the REVISED ASUOI observation tool, employing an independent-samples t-test to establish differences between the graduate coaches and non-graduate coaches across each of the behaviour categories. Differences were identified in five categories – Learning Intention, Closed Questioning, Open Questioning, Coaches’ Model, and Observation. Graduateness as outlined by Coetzee (2014), was proffered as an explanation of differences. Further work is suggested using conversational analyses to provide a more subtle and nuanced examination of the coaches’ vocabularies and judgements as they communicate.

Diabetes Mellitus (DM) which is characterized by pancreatic beta-cell dysfunction, peripheral insulin resistance, or both, is one of the most relevant cardiovascular risk factors worldwide. Its most prevalent and studied form is type 2 diabetes mellitus (DM2), a chronic multifunctional condition linked to physical inactivity and lifestyle. The purpose of this narrative review is to explore the implications of high intensity interval training on different hemodynamic, biochemical and anthropometric parameters of DM2 patients. Findings yielded that high-intensity interval training is a safe and recommended training method to improve functional capacity and certain parameters such as body weight and body mass index (BMI), systolic blood pressure (SBP), VO2 maximum (peak) and Hb1Ac, compared to moderate and low intensity training, and passive controls. Moreover, the benefits of physical exercise are independent of weight loss and there is no nutritional protocol or drug to replace them.

Purpose: This study investigated the relationships between swimming speed and physiological and perceptual responses in a skins race, in which a maximum of three races are repeated with a rest in between each round. Methods: The study measured the physiological responses in terms of the heart rate, maximal oxygen uptake (VO2max), and oxygen debt (O2 debt) and examined the perceived exertion to determine the perceptual response. Specifically, it measured the swimming speed and blood lactate (Bla) levels of seven male collegiate swimmers in three rounds of 50 m freestyle, which simulated skins race. It also conducted a bicycle ergometer test to measure their VO2max and O2 debt. Results: The results showed a significant association between swimming speed and Bla. In other words, the study found a significant association between swimming speed and glycolysis during the skins race. However, it did not find a significant association between swimming speed and VO2max or/and O2 debt. Conclusion: Hence, it concluded that a swimmer’s skill level is related to the swimmer’s speed in the skins race. These findings provide an understanding of the physiological parameters that effect performance in high-intensity sports.

The aim of this study was to: 1) compare the anthropometric characteristics of elite male taekwondo athletes between selected weight categories using the ‘full’ International Society for Advancement of Kinanthropometry (ISAK) profile; and 2) compare the index of sitting height/stature ratio, and lower-limb segment lengths between standards of competitors. Thirty-two elite male taekwondo athletes volunteered to take part and they were categorised according to five competition weight categories (<58, <63, <68, <74, and <87kg). Anthropometric measurements were performed according to the ISAK profile protocol (42 measures), and the data were compared between the weight categories. Athletes were also divided into two groups based upon their previous success and selected variables were compared between the groups. Significant differences were identified in a range of anthropometric variables between athletes’ weight categories, including percentage of body fat [%BF], skinfold thickness, measurement girths, lengths and widths, and somatotype components. Such differences were generally more notable between the lighter (<58kg) and heavier (<63, <68, <74, and <87kg) weight categories, with lighter weight categories tending to exhibit lower %BF, skinfold thickness, smaller/shorter specific limb girths, breadths, and lengths, and lower endomorphy when compared with their heavier weight counterparts. International level athletes displayed significantly lower sitting height/ stature ratio, and greater iliospinale and tibiale laterale height than their national level counterparts (p < .05). The findings of this study provide focused reference values to assist preparations for selected weight categories within the sport, and they offer a framework to support talent identification programmes.

The glenohumeral joint is the third most common joint to be affected by osteoarthritis (OA). Practising volleyball can lead to shoulder arthritis due to repetitive mechanical stress on the shoulder joint. The first step of management of primary glenohumeral OA usually is the non-operative treatment, with intra-articular injections representing one of the most utilized treatments. The aim of this study is to report the outcomes of a series of three injections of hyaluronic acid (HA) plus sorbitol in a patient with severe glenohumeral OA. An 81-year-old female former volleyball player presented to our Rehabilitation Unit with more than 15 years history of shoulder pain and functional limitation. Since she refused to undergo surgery, we proposed her intra-articular injections of HA plus sorbitol. Outcome evaluation was made up to 12 months from the last injection by means of the Constant-Murley score and the Disability of the Arm, Shoulder and Hand questionnaire. Three injections of HA plus sorbitol for three weeks in a row in a patient with severe glenohumeral OA led to important improvements in pain reduction and better functionality at all follow-ups. Larger studies including more patients and with longer follow-ups are needed to confirm the consistency of these findings.

The objective was to compare the effect of five mineral water mostly consumed in Cameroun on performance, haematological and behavioural parameters in rats. Twenty-four rats (140 g) were used for this study. Among the groups, there are a control group which received deionized water and five experimental groups which received different mineral water (Tangui, Supermont, Opur, Aquabelle and Semme) during 21 days. Rats were allowed for swimming exercise every alternate day between 11h and 17h. On the day 21, rats from each group were subjected to the forced swimming test with tail load. One hour after the forced swimming test, the open field test was carried out to evaluate their behaviour. Water and food consumption, body weight, relative organ weight and haematological parameters were evaluated. Results showed that all the mineral water used during this experimentation did not have any effect on water intake, food consumption, body weight and relative organ weight (p > .05). Significant increase (p < .01 – p < .001) in swimming time of rats consuming Tangui (445.00 ± 43.60 seconds) and Opur (450.80 ± 51.03 seconds) were observed as compared to the control group (325.50 ± 24.37 seconds). Results of behavioural and haematological parameters showed significant modifications in the same groups in comparison with control group (p < .01 – p < .001). Differences of swimming time, hematologic and behavioural parameters observed in rats having consumed Tangui and Opur could be due to the quantity of some minerals (calcium and magnesium) present in those drinks.
目的是比较喀麦隆主要消费的五种矿泉水对大鼠的性能、血液学和行为参数的影响。实验用大鼠24只(140 g)。其中，对照组饲喂去离子水，5个试验组分别在21 d内饲喂丹桂、Supermont、Opur、Aquabelle和Semme矿泉水。每隔一天11 ~ 17小时进行一次游泳运动。第21天，各组大鼠进行尾载强迫游泳试验。在强迫游泳试验1小时后，进行野外试验，评估它们的行为。评估水和食物消耗、体重、相对器官重量和血液学参数。结果表明:本试验期间所使用的各种矿泉水对采食量、摄食量、体重和相对脏器重量均无显著影响(p > 0.05)。与对照组的游泳时间(325.50±24.37秒)相比，服用坦桂组的游泳时间(445.00±43.60秒)和Opur组的游泳时间(450.80±51.03秒)显著增加(p < 0.01 ~ p < 0.001)。行为学和血液学指标与对照组比较差异有统计学意义(p < 0.01 ~ p < 0.001)。在饮用坦桂和欧普洱的大鼠中观察到的游泳时间、血液学和行为参数的差异可能是由于这些饮料中存在的某些矿物质(钙和镁)的数量。

This work, by means of in-depth research and systematic review, aims to demonstrate whether there is a real and concrete correlation between motor education and the learning of logical-mathematical concepts in school-age children between 6 and 11 years. Initially, several protocols and interventions were selected using targeted electronic databases focusing research on the last ten years. Subsequently, the main theme was addressed, subdividing, and analysing the selected research based on four topics: literature, gesture, interdisciplinary and testing. In the theme "literature" two works have been compared concerning the learning of logical-mathematical concepts thanks to the introduction of the use of literature for children and manipulators. In "gesture" five works have been compared where mathematical learning took place through the association of gesture with explanation. The nine protocols signed "interdisciplinary" deal exclusively with this topic: how the movement and the use of the body intervene on mathematical learning. Finally, three data collection on the topic "test": how physical activity intervenes on the results of mathematical tests. Bibliographic research shows that pupils participate with interest in activities and there is no negative influence on this link, indeed a significant improvement was evident in most of the protocols and interventions. There is, however, the need to monitor research in the long term, to expand with a larger sample of children and use larger spaces.
