Změny utváření zevnějšku starokladrubských koní / Changes of body conformation of Old Kladruby horses

KARDOVÁ, Lenka January 2014 (has links)
Horses have been companions to humans for thousands of years, both as work animals and as part of our culture. The Old Kladruber horse is a Czech autochthonous breed included in animal genetic resources. The aim of my thesis was to assess the gradual change in the external features of Old Kladruber horses in the years 1900 2013 in both the colour variants. I focused on 5 body measurements (height at the withers measured by tape, height at the withers measured by stick, girth of chest, girth of bone) collected for 1021 horses registered in the breed registry. The obtained values have been summarized and subsequently statistically and graphically evaluated. The results imply that values of wither height of Old Kladruber horses measured both by tape and stick have been increasing, whereas their weight has slightly dropped. In white horses, the average increase in the tape-measured wither height amounted to 3.5 cm and to 7 cm in black horses. Stick height at the withers has shown an increase ranging between 3 4.7 cm in white horses, while in black horses, the values ranged between 6 10 cm. In stallions, the chest girth was determined at 197.5 cm. White mares had a chest girth of 199.55 cm. Almost identical value, i.e. 198.13 cm, was determined for black mares. The bone girth has remained almost unchanged. A slight decrease was observed in white Old Kladruber horses stallions in the years 1970 2013 by 0.5 cm. This change was most probably caused by the addition of blood of other breeds in the past. A drop in the weight was monitored over the time interval of 1930 2013 and it ranged between 22 kg and 73 kg according to the monitored group. This drop in the weight and increase in the body frame implies a change in the type of the horse, tending rather to the sports type. However, this change can also be affected by the conditions in the environment. Only in unique cases, the values of the variation coefficient in the years 1990 2013 exceeded the limit of 10%. Groups of monitored horses of both colour variants can thus be considered balanced. In the years 1990 2013, several horses of a non-compliant standard height were also included in the breed. This was required as part of the attempt to preserve all of the existing lines and families as well as to keep the coefficient of relationship low.

Orientador: Antonio de Queiroz Neto / Banca: Guilherme de Camargo Ferraz / Banca: Kênia Cardoso Bícego / Banca: José Arnodson Coelho de Sousa Campelo / Banca: Fernando Queiroz de Almeida / Resumo: Testes que avaliam o desempenho e direcionam a intensidade de treinamento de cavalos, como a aferição do limiar de lactato (LL), são muito úteis na medicina esportiva equina. O presente estudo visa determinar se a velocidade correspondente à concentração de lactato mínimo (VLACMIN) é dependente do protocolo utilizado. A VLACMIN determinada por meio de 5 protocolos (P1 - P5) foram comparados com a velocidade obtida no Teste da Máxima Fase Estável de Lactato (VMAFEL). Oito cavalos árabes treinados foram submetidos a várias sessões para determinação da VMAFEL e comparados com 5 protocolos diferentes. Estes protocolos incluíram um período de aquecimento, seguido de um galope de alta intensidade. Após a corrida, a velocidade foi reduzida para 4 m.s-1. Em P1, P2 e P3 o incremento de velocidade foi fixado em 0,5 m.s -1 e as durações das etapas foram de 3, 5 e 7 min, respectivamente. Em P2, P4 e P5, a duração das etapas foi fixada em 5 min, e o incremento de velocidade foi de 0,5; 1,0; e 1,5 m.s-1, respectivamente. A VLACMIN foi determinada pela aplicação de uma função polinomial de segundo grau. A média e desvio-padrão da VLACMIN dos valores de P1, P2 e P3 e do VMAFEL foram respectivamente: 5,61 ± 0,12 m.s-1; 5,26 ± 0,17 m.s-1; 4,96 ± 0,36 m.s-1; 5,48 ± 0,18 m.s-1 e houve diferença significativa quando comparamos VMAFEL e P3 . A média e desvio-padrão da VLACMIN dos valores de P2 , P4 e P5 e do VMAFEL foram respectivamente: 5,26 ± 0,17 m.s-1; 5,84 ± 0,45 m.s-1; 5,99 ± 0,43 m.s-1; 5,48 ± 0,18 m.s-1, e houve diferença significativa quando comparamos VMAFEL e P5. É possível concluir que a capacidade aeróbia mensurada por meio do método VLACMIN é dependente da duração da etapa, e do incremento da velocidade, nas condições analisadas. / Abstract: Tests to evaluate the performance and direct the intensity of the horses' training, such as the determination of the lactate threshold (LT), hold a great importance in the equestrian sports medicine. The present study aims at determining whether the speed corresponding to the minimum lactate concentration (VLACMIN) is dependent on the protocol used. The VLACMIN determined through 5 protocols (P1 - P5) were compared with the speed obtained in the Lactate Maximum Stable Phase Test (VMFEL). Eight trained Arabian horses underwent several sessions for the VMFEL determination and compared with 5 different protocols. These protocols included a warm-up period, followed by a high-intensity galloping. After the run, the speed was reduced to 4 m.s-1. In P1, P2 and P3 the speed increment was established at 0.5 m.s -1 and the phase durations were of 3, 5 and 7 min, respectively. In P2, P4 and P5, the phases duration was established at 5 min, and the speed increment was of 0.5; 1.0; and 1.5 m.s-1, respectively. The VLACMIN was determined through the application of a second-degree polynomial function. The mean and standard deviation of the VLACMIN of the P1, P2 and P3 values, as well as of the VMFEL, were respectively: 5.61 ± 0.12 m.s-1; 5.26 ± 0.17 m.s-1; 4.96 ± 0.36 m.s-1; 5.48 ± 0.18 m.s-1 and there was significant difference when we compared VMFEL and P3 . The mean and standard deviation of the VLACMIN of the P2 , P4 and P5 values, as well as of the VMFEL, were respectively: 5.26 ± 0.17 m.s-1; 5.84 ± 0.45 m.s-1; 5.99 ± 0.43 m.s-1; 5.48 ± 0.18 m.s-1, and there was significant difference when we compared VMFEL and P5. It is possible to conclude that the aerobic capacity measured through the VLACMIN method is dependent on both the phase duration and the speed increment, in the conditions analyzed. / Doutor

Chramosta, Roman January 2021 (has links)
Title: Evaluation of selected parameters in American football players as possible causes of their injuries Objectives: The aim of this thesis is, after studying selected theoretical backgrounds, to point out at the performance players of American football deliberately selected team to the possible causes of injuries (with special focus on the area knee joint) by evaluating body parameters, then selected three tests and at the same time by evaluating the screening of two positions in progress vertical jump. Methods: To write down the diploma thesis, we mainly used knowledge and conclusions from a literature search of foreign articles and studies dealing with the issue of injuries, injury prevention, sports performance, and normative data. In the next step, testing of selected three tests and subsequent normative evaluation was performed. Screening was also important for the evaluation of two positions during the vertical jump. Results: Through hand-picked performance tests, it was found that the selected players from the team achieved a sufficient level of movement based on the results according to standardized tables that we used. In comparison with professional players and the norm set out by Palmieri (2019), the players that we tested lag behind. As for the injuries in the selected group, the...

Hodnocení počtu a kvality potomstva hřebců slezského norika / Evaluation number and quality of offspring stallions Silesian noriker

BARTOKOVÁ, Markéta January 2015 (has links)
The Silesian noriker is an original Czech breed of a coldblooded horse whose stud book was approved by the Ministry of Agriculture in 1995.The Silesian noricker is a strong coldblooded horse with a relatively less harmonious body structure used at present not only in agriculture and forestry but also for rehabilitation and recreation purposes. The aim of the diploma work was to work out a list of information about stud horses being in the contemporary stud as noted down in the stud book. Besides, the work focuses at proving a possible existence of the differences between the outcome of the evaluation of the exterior, performance tests and the characteristic features inherited by the descendants of the stallions. Moreover, the main aim of the work was to find out if there are individuals among stud stallions which have sufficient number of descendants being able to provide an objective evaluation of heredity control. Studbook Silesian noriker recorded 44 sires, of which only 23 subjects had descendants in breeding; the number was 266 individuals. The stud book of the SN kept files of 44 stud stallions out which only 23 individuals had descendants in stud, whose number was 266. The data for the purpose of the analysis have been based on the records in the stud books of the association of the unions of horse breeders: body measurements, evaluation of the exterior and the results of the performance tests. All the data have been presented and evaluated both in charts and graphs. In conclusion, stallions having 10 and more descendants have been evaluated in detail and the results of the latter have been compared with the average ones of SN in stud. The analysis has proved that only 68% of the whole number of descendants is represented by those written in the stud book of SN. The average body measurements were: stick withers 159,07 cm; tape withers 170,88 cm, chest perimeter 204,85 cm, shin perimeter 23,20 cm. The evaluation of the exterior showed the average result 7,47 points. The final result of the performance tests was 7, 47 points. According to the detailed analysis, out of 75 descendants only 44% belonged to SN. The Top rated offspring (exterior 7,76 and results performance tests 8,03) had of stallion Steiman 2885

Avaliação do desempenho motor de escolares, entre 11 e 14 anos de idade, do ensino fundamental de escola pública de Santa Maria, RS: estudo de caso / Evaluation of motor performance of students, from 11 to 14 years old, of elementary education of public school in Santa Maria, RS: study of case

Etchepare, Luciane Sanchotene 05 June 2004 (has links)
The purpose of this study is to provide to Physical education teachers knowledge about evaluation of motor performance in elementary school. The motor performance was characterized by the variables of motor skill, corporeal-kinesthesis intelligence, and motor fitness. Those variables were measured through three batteries of tests: the Bruininks-Ozeretzky Battery (BOB) to measure motor skill; Xavier Battery (ICC) to measure corporeal-kinesthesis intelligence; and one battery test to measure motor fitness. The sample was composed by 67 boys and 83 girls, aged between 11-14 years, enrolled in the municipal system of teaching in Santa Maria. The sample performed the three batteries in different periods of time and afterwards participated in individuals enterview. It is possible to conclud that all batteries above may be used in any brazilian public school, as long as they are adapted to the environment available. What and how to evaluate should depend on the objectives and goals planned by teachers and students. The choice of tests and/or test batteries will depend on the knowledge of the teacher related to the use of materials, concerning to the variables that are being evaluated as well as interpreting the results. It is not enough to only choose the right instruments. The teachers should be certain about the physical space, the abilities to measure, the useful time to use the instruments, the number of students and the number of staff needed, and also about the material available. The brazilian teachers of public schools have a great knowledge about their field of work, a lot of creativity and dedication, since today, the lack of material can t be use as an excuse for their pedagogic failure. / Busca-se, através deste estudo, proporcionar aos professores de Educação Física conhecimentos relacionados à avaliação do desempenho motor nas séries finais do Ensino Fundamental. O desempenho motor foi caracterizado pelas variáveis: Proficiência Motora, Inteligência corporal-cinestésica e Aptidão Motora. Estas variáveis foram medidas através de três baterias de testes: a Bateria de Bruininks-Ozeretzky (TBO) para medir Proficiência Motora, a Bateria de Xavier (ICC) para medir Inteligência Corporal-cinestésica e uma bateria de testes para medir Aptidão Motora. Compõem a amostra 67 meninos e 83 meninas da Rede Municipal de Ensino de Santa Maria regularmente matriculados nas séries finais do Ensino Fundamental e na faixa etária dos 11 aos 14 anos. A amostra foi submetida as três baterias de testes em períodos diferentes e posteriormente a entrevistas individuais. Conclui-se que todas as baterias citadas anteriormente podem, desde que adaptadas, serem aplicadas nas condições oferecidas pelas escolas públicas brasileiras. O que e como avaliar deve sempre depender dos objetivos e das metas previamente estabelecidas pelos professores e alunos. A escolha dos testes e/ou baterias de testes vai depender do grau de conhecimento do professor avaliador, quanto aos instrumentos escolhidos tanto no que se refere as variáveis avaliadas como na interpretação posterior dos escores encontrados. Não basta escolher adequadamente os instrumentos de coleta de dados, os professores devem ter o máximo de certeza quanto ao espaço físico, as habilidades a serem medidas, o tempo útil para a aplicação dos instrumentos, o número de sujeitos avaliados e de avaliadores necessários e a disponibilidade de materiais. Os professores de escolas públicas brasileiras devem, ter um vasto conhecimento sobre a sua área de atuação, muita criatividade e dedicação ao desempenhar seu papel, pois hoje a falta de recursos materiais não serve mais como desculpa para os fracassos pedagógicos.
