Aim: The aim of this study was to determine the effect of a 15-minute bathing session in a Finnish sauna on changes in systolic and diastolic blood pressure (SBP and DBP, respectively), heart rate (HR), and body mass. The effects of grouping variables (age, sex, BMI, frequency of sauna use, history of sauna use) were taken into account in the analysis. Materials and Methods: A total of 60 women (33.6±13.1) and 42 men (33.8±12.5) aged 17 to 79 participated in one 15-minute sauna session (temperature: 90-91°C; relative humidity: 14-16%) in December 2019, in the city of Wrocław, Poland. The participants’ body mass, SBP, DBP and HR were measured before and after sauna. Body height was measured only before sauna. Results: Sauna induced significant changes in the participants’ physiological parameters. Systolic blood pressure decreased (p<0.05) in both sexes, in older participants (p<0.001) regardless of their BMI, and in participants who had rarely used sauna and had used sauna for a minimum of several years. A significant decrease in DBP (p<0.001) and HR values and a significant loss of body fluids (p<0.001) was noted in both sexes regardless of age, BMI, frequency and history of sauna use. Conclusions: A 15-minute sauna session has a beneficial effect on the circulatory system and can be incorporated into cardiovascular therapies. Regular sauna use is an important factor, and optimal results can be achieved by visiting sauna several times a week.

Objectives: The roles of cardiorespiratory fitness (CF) in reducing cardiovascular disease (CVD) and all-cause mortality risks are well established; however, little is known about the role of CF in reducing risk of metabolic syndrome (MetS), a cluster of CVD risk factors, particularly in Asian countries. This research examined associations between CF and MetS diagnosis and its five components in Indonesian middle-aged and older adults. Methods: This cross-sectional study included 161 participants (aged 63±8 years; 70% female). CF was assessed with a 6-minute walk test. MetS diagnosis and its components were assessed with the Adult Treatment Panel III. Logistic regression modelling was conducted to examine the relationships between CF and MetS diagnosis and its components, after adjustment for BMI and other confounders. BMI was categorized using cut-points for Asians. Results: In adjusted models, participants with low CF had a greater likelihood of being diagnosed with MetS than those with high CF (OR=4.79, 95%CI:2.17-10.62). They were also more likely to have low high-density lipoprotein (OR=2.07, 95%CI:1.02-4.18) or hypertriglyceridemia (OR=2.37, 95%CI:1.15-4.86). There was also borderline significant findings that suggested that participants with low CF had greater likelihood of having abdominal obesity (OR=2.34, 95%CI:0.97-5.65, p=0.06) or hyperglycaemia (OR=2.07 95%CI:0.98-4.41, p=0.06). Conclusions: Low CF is associated with increased likelihood of being diagnosed with MetS. The adverse effects of low CF are mainly characterized by dyslipidaemia. Public health messages should emphasise the importance of improving CF for preventing MetS. Assessment of CF could be useful for targeting individuals most likely to benefit from intervention to prevent MetS.

The aim of the study was to analyze step counts of middle school students in structured and unstructured physical education classes (PE) according to age, gender, and school type. Data were collected on a sample of 74 students, 40 7th and 34 8th grade students recruited from private and public middle schools. Omron HJ-112 pedometers were used in this study to obtain step counts. There were statistically significant differences between boys and girls in the step counts in both structured and unstructured PE. A significant difference was observed between school types in step counts during structured PE in both genders, while no significant difference was found for unstructured PE. Significant difference was found between step counts of only boys of different grades in unstructured PE. Boys made more steps than girls both in structured and unstructured PE. In structured PE, 7th grade boys reached a higher number of steps than 8th grade boys.

Introduction. Leisure may provide certain unique subjective well-being (SWB) benefits that cannot be obtained through other domains in life, as leisure is typically characterized by autonomy or greater freedom of choice than other life dimensions. The objective of the present study was to analyse the level of SWB in male and female high school students with different health status preferring sedentary leisure time activities and compare SWB dimensions (SWB-Ds) between healthy students and students with self-reported health disorders (S-RHDs). Material and Methods. The research sample comprised of 153 male students (healthy; n=90 and with S-RHDs; n=63) and 238 female students (healthy; n=126 and with S-RHDs; n=112) who preferred sedentary types of leisure time activities. A standardized The Bern Subjective Well-Being Questionnaire for Adolescents (BFW) was used as a primary research method. Non-parametric Mann Whitney U-test was used to assess differences between two independent groups of male and female high school students according to their self-reported health status (healthy vs. with S-RHDs). Results. Significantly higher level of negative SWB-Ds was found in the group of male students with S-RHDs compare healthy male students (U=1672, p=0.000, r=0.34). No significant differences were found in the comparison between healthy female students and female students with S-RHDs. Conclusions. Many researches indicate a very close positive connection between regular participation in sport leisure activities and SWB, but just few of them investigate correlations and comparisons among SWB, health status and sport leisure activities participation

Background. Experts note the low level of physical fitness of female students. Fitness programs that balance the development of cardiorespiratory and strength fitness level are necessary in the physical education practice of students. The purpose of this study is to compare effectiveness of two exercise programs in terms of strength endurance and cardiorespiratory of female students in physical education. Material and Methods. Female students (n=36) practicing fitness–aerobics (G–1) and resistance training (G–2) participated in the research. All students participated in 52 training sessions. The students (G–1) practiced step aerobics with strength training combination. The students (G–2) practiced resistance training with Kangoo–Jumps fitness combination. The level of cardiorespiratory and strength fitness was studied using tests: VC, Stange test, Step test (PWC170), Running test, Push–Up test and others. Results. Students (G–1) had a reliable advantage in test results: VC, Stange test, Step test (PWC170), Running test, at the research beginning. Students (G–2) showed significantly better results in tests: Burpee test, Push–Up test and Stange test at the end of research. Reliable differences in tests: Plank test and Heart Rate in favor of female students (G–2) were revealed. The results of other functional tests did not differ significantly. Conclusions. The possible effectiveness of aerobic fitness training Kangoo–Jumps in resistance training of female students was discovered. A significant increase in the indicators of strength endurance and cardiorespiratory fitness of young women was revealed.

Introduction: The issue of talent selection and identification has been addressed by a variety of authors. However, few studies focus on sports recommended to be practiced by children on the basis of evaluating their performance or sports profiles. Material and Methods: The purpose of the study was to determine individual sports profiles of child athletes and nonathletes and recommend sports to be practiced. The participants were children aged 6 and 7 years who were first graders at elementary schools. Child athletes were children who participated in organized sports practice in soccer (n = 16), ice hockey (n = 29), and artistic gymnastics (n = 10). Child nonathletes (n = 26) did not participate in any organized sports practice within extracurricular activities or in sports clubs. Children performed a battery of 9 tests: sit-and-reach test, flexed arm hang (overhand grip), repeated routine with a stick, sit-ups, standing long jump, 4 x 10-meter shuttle run, rolling of three balls, 20-meter sprint and endurance shuttle run. To assess decision-making processes, children played a chasing game called "pull-the-flag" game. Results: As for the match between the sports practiced and the sports recommended to be practiced by child athletes, 20 children practiced the sports that were also recommended to be practiced on the basis of their individual sports profiles. According to their sports profiles, child nonathletes were recommended to do, in particular, rhythmic gymnastics, cycling, volleyball, tennis, and floorball. Conclusions: We may conclude that low number of children practice sports that match children’s motor dispositions. Therefore, individual sports profiles need to be devised to provide children with recommendations concerning sports that match their talent.

Introduction: Start performance in swimming plays a major role in determining the final standings, especially in sprint races. The purpose of the study was to determine kinematic parameters underlying the kick start from OSB12 in terms of the kick plate position and shoulder positioning at the start. Material and methods: The sample included 8 non-randomly recruited performance-level swimmers whose average age, body height, and body weight was 17.4 ± 1.8 years, 182.2 ± 3.4 cm and 81.00 ± 3.9 kg, respectively. To measure the kinematic parameters, we used the SwimPro camera system. The parameter rs measured included angular parameters and kinematic parameters for each of the start phases: block phase, flight phase, and water phase. We processed the collected biomechanical data using the Statistica 12.0 software. To determine significant differences between the kick plate positions in three types of start, we applied the Mann-Whitney U test. Results: We found significant differences (p<0.05) in the selected kinematic parameters in all phases, which depended on the OSB12 kick plate position and basic starting position (front-, neutral-, and rear-weighted). The greatest differences in the parameters measured were found between the front-weighted start and rear-weighted start. We may conclude that performance-level swimmers should adjust the rear kick plate to positions 3 and 4 and assume the following starting position: front knee angle between 131° and 133°, rear knee angle around 80°, and trunk angle between 40° and 41°. This starting position affects the flight phase, namely takeoff angle (40⁰-41⁰), head position at takeoff (1.33-1.38 m), flight time and distance (0.346-0.368 s; 2.74-2.79 m), entry angle (38⁰). The starting position also affects the glide phase, namely the glide time and distance (0.532-0.536 s; 2.22-2.26 m) and maximum depth (-0.91-0.92 m). Conclusions: The results of the study show that swimmers produced shorter times to 5 meters and higher velocity at 5 meters compared with other starting positions and OSB12 kick plate positions.

The purpose of this study was to evaluate the changes of speed, agility and power performance during one soccer season and the impact of functional fitness on changes in motor performance in elite female soccer players. This study was conducted with 18 members of the Polish Women’s National Football Team. The analyzed training season was divided into four training phases. Physical performance was assessed by a test of quickness the 5m sprint, tests of maximal speed the 30 m sprint, test of agility L-run test and tests of lower limb explosive power counter movement jump (CMJ) and counter movement jump with arm swing. Functional fitness was assessed using the Functional Movement Screen (FMS). Individual functional training as well as a training plan based on FIFA 11+ prevention were utilized. The analysis showed significant improvement in the CMJ test (F=3.02, p<0.05) and FMS score (F=5.959, p<0.01) during the in-season. Other parameters of physical performance were stable during the evaluation period. Positive correlations between baseline FMS score and changes of athletes’ 30m sprint performance (r=-0.48, p<0.05), total in-season change of FMS score and total inseason change of 5m sprint performance (r=-0.53, p<0.05) were observed. Female soccer players during the in-season demonstrated a relatively good level of physical performance which corresponds to their particular training phase. Functional fitness intervention appears to be an effective way of improving speed, acceleration, and power performance in elite female soccer players.

Functional fitness was assessed using the Functional Movement Screen (FMS). Individual functional training as well as a training plan based on FIFA 11+ prevention were utilized. The analysis showed significant improvement in the CMJ test (F=3.02, p<0.05) and FMS score (F=5.959, p<0.01) during the in-season. Other parameters of physical performance were stable during the evaluation period. Positive correlations between baseline FMS score and changes of athletes’ 30m sprint performance (r=-0.48, p<0.05), total in-season change of FMS score and total inseason change of 5m sprint performance (r=-0.53, p<0.05) were observed. Female soccer players during the in-season demonstrated a relatively good level of physical performance which corresponds to their particular training phase. Functional fitness intervention appears to be an effective way of improving speed, acceleration, and power performance in elite female soccer players.","PeriodicalId":43466,"journal":{"name":"Physical Activity Review","volume":"24 1","pages":"16-25"},"PeriodicalIF":0.9,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138516813","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 writings of early taekwondo pioneers promote peace through the practice of the martial art and, later, the combat sport. These pioneers charged taekwondo practitioners with a duty to contribute to justice, defend the weak, and build a more peaceful world. National and international taekwondo organizations such as the Kukkiwon, World Taekwondo (WT), and the International Taekwon-Do Federation (ITF) have taken up the charge of peace promotion through taekwondo by means of transnational events, such as goodwill tours and joint taekwondo demonstrations by adversarial states (e.g., South and North Korea). These activities are soft diplomacy initiatives and have seen some level of success. While these soft diplomacy activities are in line with the goal of peace promotion that the early pioneers advocated, they are qualitatively different from what the pioneers advocated. Originally, the responsibility of peace promotion was on the individual taekwondo practitioner, who ought to cultivate moral character, courage, and martial art skill in order to uphold justice and defend the weak. With the current use of taekwondo for soft diplomacy, the responsibility of peace promotion has shifted from the individual practitioner to the governing bodies, such as WT and the ITF. Instead of focusing on issues surrounding justice and the protection of the weak, these national and international organizations focus on geopolitical cooperation, which is mediated through cultural exchange activities in the form of taekwondo demonstrations. These events involve activities such as acrobatic performances, dance routines, and board breaking that require little combat skill and may not pose the risk of serious injury to the individual practitioners, mainstays of the individual heroes of old. The charge to safeguard justice and physically defend the weak, which are acts of true courage as was envisioned by the taekwondo pioneers, is mostly ignored.

Introduction: The police forces performance is demanding on well-timed and quick reaction. Single reaction time and choice reaction time are crucial when the jeopardy appears. Performing under stress in life-threatening situations needs a good level of stress tolerance. In our study, we used two nonspecific, and two specific (shooting) tests to analyse the reactivity of police officer under different conditions. Material and methods: The research sample consisted of n=18 male Czech police training instructors. The group is unique as these police officers are specialised in the professional self-defence with focus on the coercive means use and shooting skills. Two standardized non-specific tests administrated with the Vienna Test System (VTS) by Schuhfried GmbH were used for data gathering. Single reaction time (SRT) was measured by the Reaction test, stress tolerance and choice reaction time (CRT) was measured by the Determination test. Two practical non-standardized shooting tests were used for the reactivity analysis in the goal oriented environment (shooting range). Results: The single reaction time among police training instructors was M=261.56±33.60 ms, which corresponds to the 66.28 percentile of age norm. Performance in the stress tolerance test also matches the average performance in population (M=45.56 percentile of correct reactions, M=61.67 percentile of incorrect reactions, M=51.44 percentile of skipped signals). According to the Pearson correlation coefficient, there is no correlation between single reaction time in the Reaction test and choice reaction time in the Determination test (r=-0.03). There is no correlation between single reaction time in the nonspecific Reaction test and performance in the specific Shooting test 1 (r=0.06) and Shooting test 2 (r=-0.01). Conclusions: There is no relation between the results in the specific and non-specific reaction tests. Nonspecific tests of single reaction time and choice reaction time are suitable for a general assessment of motor abilities. Specific tasks need specific training and specific evaluation methods.
