Published: February 2018

Sport climbing is now seen as part of the climbing population fi tness interesting resource. Th is study clarifi es the relationship between selected conditioning tests, anamnetic data and performance in sport climbing in the climbing trips OS or RP and each points to a relationship between these ways of ascent climbing routes. Study describes the relation between the diff erent standardized tests selected from Eurofi t test set (standing long jump, full forward trunk bend, pull-up hold, manual dynamometry, „fl amingo“ exercise), anthropometric data (body height, body weight, body fat ratio in %) and anamnestic data (length of climbing experience, climbing performance in terms Red Point RP, and On sight OS). Th e dependency measure is expressed by a linear regression with two dependent variables. Th e dependent variables express climbing performance in terms of RP and OS. Th e signifi cant indicators for dependent variable RP in this given regressive model are length of climbing experience, pull-up hold, manual dynamometry and body weight; for the dependent variable OS, these are length of climbing experience, pull-up hold and manual dynamometry. Aft er the application of a linear regression analysis with two dependent variables, the dependency measure between the RP and OS performance was formulated as a partial correlation rp = 0,745.

The case study deals with the infl uence of six months intervention program onto the change of the level of static and dynamic balance, orientation in the space and the strength of lower limbs at selected individuals in the period of seniority. Th ese abilities are considered to be limiting in the life of seniors. Th e complex was created by four individuals, two men and two women at the age of 88, 83, 81, 82. Th e needed datas to judge the level of monitoring locomotive abilities we obtained before and aft er fi nishing locomotive intervention by the help of six choosen standard motoric test. Th is intervention locomotive programme lasted for six months, it was carried out twice a week always 60 minutes. We were looking for some information regarding state of health and lifestyle, which could infl uence observed abilities at individuals. The level of static balance got worse at three individuals also aft er pointed exercises. Th is ability was proved as the most susceptible by health problems and by evolutionary process. At any of individuals wasn´t proved any decreasing of the level of dynamic balance, space orientation or the strength of lower limbs. It is not possible to generalize the fi ndings but they are the proves of contribution to the quality of life by the individually choosen intervention.

Published: February 2018

This article looks at the evolution of structure teams in the highest Czech basketball league. The tracking period is since seasons 1998/99 to 2008/09. This research is based on content analysis of game statistics from particular games. The sample of players is classified into three groups (Czech players younger than twenty years, Czech players twenty years old and older, foreign players) and evaluates statistical characteristics by the comparative method. These include the number of players, minutes played, points scored and coefficient of usefulness. The results confirm the expected increase of the number of foreign players as well as continuously growing impact on the game. The impact is expressed as a coefficient of player’s utility. In contrast to this, the trend of participation and usefulness of Czech players younger than twenty years is shown to be diminishing. The hypotheses of our studies are therefore proven valid. The article refers to the change of the team constitution.

The offer of leisure time activities for persons with disabilities in the Czech Republic is still not paying enough attention. Our aim is to find out what is the offer of services and obstacles for the expansion of its menu. These findings can then be used for more effective support to the development of these bodies, extensions and targeting of activities for persons with a Disability or other special needs. Research investigation was attended by 40 of 165 originally polled bodies (educational and nonschool organizations, commercial businesses and non-profit organizations) in the 6 counties. 55 % of them carries out actions for persons with a disability, most commonly combined and physical. The children of school age are the main focused group, and it is a single (rather than annual) event is an educational and artistic focus. Although it is based on 97,5 % of organizations to implement meaningful events for persons with a Disability, has only 25 % of them plenty of information and resources for their implementation.
Analýza efektu vysoce intenzivního intervalového tréninku (HIIT)
Authors: Kolínský Roman , Cacek Jan , Strašilová Kateřina , Zháněl Jiří 
Published: February 2018

The HIIT – High Intensity Interval Training has become an increasingly used term in foreign publications and this method is frequently implemented in training processes of many athletes. However not every athlete or trainer is aware of the physiological changes which are caused by this form of training. In order to improve the training process it is important to compare the effectiveness of HIIT with the continual training method or other forms of the interval training. The aim of this publication is to analyze and describe the effect of various forms of HIIT according to the set markers: primarily VO2 max (maximal oxygen uptake) – interval training effectiveness marker, secondarily lipid utilization, and last but not least hormonal and enzymatic level changes. Another objective of this publication is the clarification and explanation of energy coverage, metabolism and cardio-respiratory function during the application of HIIT method. Within the research plan we focused exclusively on the foreign studies (n = 150) conducted in years 1978–2015 from which we chose 70 studies from databases such as SportDiscus, Web of Science, ACSM Journal, PubMed. The selection was based on the preselected criteria – length of the research, nature of the research group and intervention frequency etc. For the purpose to extend the theoretical bases of the problematics of energy coverage, metabolism and cardio-respiratory function were analyzed several chosen studies from last 10–15 years. The analysis of the individual markers was conducted based on the publications from the last decade. The research has shown that the HIIT has a significant effect on the increase of VO2 max. Further findings also showed that the subject is able to adapt to this type of training in just two weeks which enables the duration of training process to shorten. This type of training also leads simultaneously with EPOC effect (post-exercise oxygen consumption) to higher energy consumption in tens of hours. The presented results can be used in Sports practice to overcome the performance stagnation and lead to performance improvement as a result of the HIIT method implementation. Certain studies show that the HIIT method is also successfully applicable to the overweight individuals, patients with Diabetes mellitus and people with sedentary lifestyle. However, it is always necessary to ensure the individual approach and to avoid the risk of overtraining.

Authors: Kalkusová Lucie 
Published: February 2018

The article contributes to the illustration of the importance of outdoor courses for development of social relationships in school classes. Following text is a pilot study for future research. The research sample consisted of 17 pupils of Grade 6 primary school, average age 11.24 years, who participated on a three-day outdoor course. The course focused on the development of team dynamics, cooperation and social relationships. The participants filled in the same questionnaire before and after the course which enabled to compare the changes. The questionnaires were based on rating all classmates according to the preferential relationships. The strength of these relationships was transformed visually in sociomaps showing the structure of social relationships. The sum of ratings given by the whole class increased from 1583 before to 1751 points after the course. The general colour of sociomap changed after the course showing increased sympathies between the classmates after the course. Sociomapping showed to be a useful and lucid method for illustration of positive impact of the outdoor course for the development of social relationships in the school class.
Relative age effect při Mistrovství Evropy ve fotbalu 2016

Published: February 2018

The theory called the Relative Age Effect (RAE) has been discussed in many sports for decades. It is based on the assumption that athletes born in the early months of the year have an advantage over the athletes born later in that particular year. The influence of earlier birthdate was proved particularly during adolescence, relatively younger individuals are often more advanced mentally and physically as well as in terms of fitness. Therefore, they are usually labelled as sports talents. This benefit can significantly affect the probability of being selected into elite group of athletes or national teams. In the present research we investigated whether the effect of RAE can be proven in the players in the European Football Championship 2016. The research sample included players from all 24 participating teams (n = 552), the research data were obtained from http://www.eurofotbal.cz/euro-20/ and were analysed based on selected criteria (player position, date of birth, ranking in the groups). Statistical analysis of the research data showed that the influence of RAE is statistically significant in all players in the championship (χ2 = 69,82, p = 0.00). The analysis of the influence of RAE on rank in the group showed that the influence of the RAE. When considering the influence of the RAE on individual player positions, the effect was nonsignificant only in forward position players (χ2 = 6,37, p = 0.09). The above results showed a similar degree of influence of RAE on adult footballers (participants of ME 2016), then it is in youth age categories. RAE issues in sport can be considered as significant and especially coaches in youth categories should be familiar with it.
Satellite Geodesy Captures Offset Magma Supply Associated With Lava Lake Appearance at Masaya Volcano, Nicaragua
Authors: Stephens K. J. , Wauthier C. 
Published: February 2018

AbstractAscending and descending Interferometric Synthetic Aperture Radar data sets from various satellites (CSK, RSAT‐2, ALOS‐2, and Sentinel‐1) show a maximum of ∼8 cm ground inflation in Masaya caldera over a 10 month period (6 November 2015 to 1 September 2016). The center of inflation is located in the NW part of the caldera, north of the active Santiago vent which has hosted a new lava lake since 11 December 2015. Simultaneous inversions of those Interferometric Synthetic Aperture Radar data sets using a neighbourhood algorithm demonstrate that a spherical magma reservoir explains the geodetic data, with a horizontal location ∼3 km north of the active Santiago vent and a depth‐to‐center ∼3 km. The associated modeled volume increase (∼0.0042 km3) is lower than the “excess” magma volume inferred from gas measurements from November 2015 to February 2016. The magma reservoir offset from the current center of eruptive activity may be the result of preexisting caldera structures.

AbstractThe deep inspiration breath hold (DIBH) and prone (P) position are two common heart‐sparing techniques for external‐beam radiation treatment of left‐sided breast cancer patients. Clinicians select the position that is deemed to be better for tissue sparing based on their experience. This approach, however, is not always optimum and consistent. In response to this, we develop a quantitative tool that predicts the optimal positioning for the sake of organs at risk (OAR) sparing. Sixteen left‐sided breast cancer patients were considered in the study, each received CT scans in the supine free breathing, supine DIBH, and prone positions. Treatment plans were generated for all positions. A patient was classified as DIBH or P using two different criteria: if that position yielded (1) lower heart dose, or (2) lower weighted OAR dose. Ten anatomical features were extracted from each patient's data, followed by the principal component analysis. Sequential forward feature selection was implemented to identify features that give the best classification performance. Nine statistical models were then applied to predict the optimal positioning and were evaluated using stratified k‐fold cross‐validation, predictive accuracy and receiver operating characteristic (AUROC). For heart toxicity‐based classification, the support vector machine with radial basis function kernel yielded the highest accuracy (0.88) and AUROC (0.80). For OAR overall toxicities‐based classification, the quadratic discriminant analysis achieved the highest accuracy (0.90) and AUROC (0.84). For heart toxicity‐based classification, Breast volume and the distance between Heart and Breast were the most frequently selected features. For OAR overall toxicities‐based classification, Heart volume, Breast volume and the distance between ipsilateral lung and breast were frequently selected. Given the patient data considered in this study, the proposed statistical model is feasible to provide predictions for DIBH and prone position selection as well as indicate important clinical features that affect the position selection.

ObjectiveWe estimated the incidence and prevalence of depression, anxiety disorder, bipolar disorder, and schizophrenia in a population‐based cohort with rheumatoid arthritis (RA) as compared to an age‐, sex‐, and geographically matched cohort without RA.MethodsUsing population‐based administrative health data from Manitoba, Canada, we identified persons with incident RA between 1989 and 2012, and a cohort from the general population matched 5:1 on year of birth, sex, and region of residence. We applied validated algorithms for depression, anxiety disorder, bipolar disorder, and schizophrenia to determine the annual incidence of these conditions after the diagnosis of RA, and their lifetime and annual period prevalence. We compared findings between cohorts using negative binomial regression models.ResultsWe identified 10,206 incident cases of RA and 50,960 matched individuals. After adjustment for age, sex, socioeconomic status, region of residence, number of physician visits, and year, the incidence of depression was higher in the RA cohort over the study period (incidence rate ratio [IRR] 1.46 [95% confidence interval (95% CI) 1.35–1.58]), as was the incidence of anxiety disorder (IRR 1.24 [95% CI 1.15–1.34]) and bipolar disorder (IRR 1.21 [95% CI 1.00–1.47]). The incidence of schizophrenia did not differ between groups (IRR 0.96 [95% CI 0.61–1.50]). Incidence rates of psychiatric disorders declined minimally over time. The lifetime and annual period prevalence of depression and anxiety disorder were also higher in the RA than in the matched cohort over the study period.ConclusionThe incidence and prevalence of depression, anxiety disorder, and bipolar disorder are elevated in the RA population as compared to a matched population.

Published: February 2018

ObjectiveTo establish receipt and provision of self‐management support for patients with inflammatory arthritis in the UK, and to establish whether receipt of self‐management support is associated with patient's knowledge, skills, and confidence to self‐manage.MethodsQuestionnaires for patients and health care professionals were sent to members and associates of the National Rheumatoid Arthritis Society. Patients completed the Patient Activation Measure (PAM), and questions about receipt of self‐management support. Health care professionals completed the Clinician Support PAM and questions about provision of self‐management support.ResultsA total of 886 patients and 117 health care professionals completed the survey. Only 15% of patients had attended a structured self‐management program. More than half of the patients reported having the skills, confidence, and knowledge to self‐manage, and this skill set was associated with receipt of self‐management support that was embedded in routine care. All health care professionals felt that patients should be actively involved in their own care, but 60% were unable to offer structured self‐management support. Health care professionals reported engaging in more embedded self‐management support than patients reported receiving in routine care.ConclusionOnly a small proportion of patients with arthritis have attended a structured support program. Although health care professionals report engaging in self‐management support embedded in routine care, patients do not necessarily agree, and these differences could impact the experience of patients with arthritis. When embedded self‐management support does occur, it is a significant predictor of patients’ knowledge, skills, and confidence to self‐manage, as opposed to attendance at a structured program.

Published: February 2018

ObjectiveTo pilot a primary care gout management improvement intervention.MethodsTwo large primary care sites were selected: 1 underwent the intervention, the other, a control, underwent no intervention. The intervention consisted of engagement of intervention‐site staff, surveys of provider performance improvement preferences, and onsite live and enduring online education. Electronic health record reminders were constructed. Both the intervention and control sites had 3 quality measures assessed monthly: the percentage of gout patients treated with urate‐lowering therapy, the percentage of treated patients monitored with serum urate, and the percentage of treated patients at target serum urate ≤6.0 mg/dl. The intervention‐site providers received monthly reports comparing their measures against their peers.ResultsBy 6 months, the intervention site significantly improved all 3 gout performance measures. The percentage treated increased from 54.4% to 61.1% (odds ratio [OR] 1.19 [95% confidence interval (95% CI) 1.08–1.31]; P < 0.001), the percentage monitored increased from 56.1% to 79.2% (OR 1.52 [95% CI 1.24–1.87]; P < 0.001), and the percentage at goal increased from 26.85% to 43.3% (OR 1.43 [95% CI 1.16–1.77]; P < 0.001). At 6 months after intervention, gout patients at the intervention site were more likely to be monitored (79.2% versus 53.4% [OR 3.54 (95% CI 2.30–5.45)]; P < 0.001) and at goal (43.3% versus 28.3% [OR 1.99 (95% CI 1.33–2.96)]; P < 0.001) than control‐site patients. Numbers treated did not significantly improve over the control site.ConclusionA pilot multifaceted gout management program can significantly improve primary care gout management performance.
