Influência da crioterapia de imersão em indicadores de dano muscular pós-exercício em atletas de triathlon

Hernandez, Sara Gabellone January 2010 (has links)
Orientador : Prof. Dr. Raul Osiecki / Dissertaçao (mestrado) - Universidade Federal do Paraná, Setor de Ciencias Biológicas, Programa de Pós-Graduaçao em Educaçao Física. Defesa: Curitiba, 30/03/2010 / Bibliografia: fls.84-94 / Área de concentraçao: Exercício e esporte / Resumo: O objetivo do presente estudo foi verificar os efeitos da crioterapia de imersão em indicadores de dano muscular induzido pelo exercício em atletas. Para tanto, 15 atletas de triatlon (Idade: 26 ±4,6, Peso: 77,4 ± 4,9 kg, Estatura: 179,3 ± 6,4 cm, %G: 11,5 ± 1,2) inicialmente realizaram uma avaliação de esforço máximo na esteira, para a determinação da FCMÁX e VO2MÁX. Posteriormente, os atletas foram divididos em dois grupos: experimental (n=8) e controle (n=7). Os dois grupos foram submetidos a um protocolo de exercícios excêntricos (4 séries de 10 repetições) para extensores e flexores de joelhos no dinamômetro isocinético. Logo após o exercício foram divididos aleatoriamente e submetidos a 15 minutos de imersão em água gelada (15ºC) ou grupo controle (15 minutos sentado). Todos os sujeitos foram submetidos a 5 coletas de sangue intravenoso sendo elas: antes do exercício, imediatamente após, 1 hora, 24 e 48 horas após o protocolo de recuperação. As variáveis sanguíneas analisadas foram: leucócitos, neutrófilos, CK, LDH, mioglobina e cortisol. Nos mesmos momentos de coletas sanguíneas foram realizadas as coletas de sensação de dor muscular por meio das escalas EVA e Likert, altura de saltos por meio do squat jump na plataforma de saltos e de amplitude de movimento (ADM) de extensão ativa de joelhos. Na análise estatística, foi utilizada a técnica descritiva (média, desvio padrão, valor mínimo e máximo), ANOVA para Medidas Repetidas seguida do Post-Hoc de Fisher para comparação entre grupos. Para essas análises foi utilizado o software Statistica 6.0, com significância fixada em p<0,05. Com relação às variáveis bioquímicas, leucócitos, neutrófilos e cortisol não apresentaram diferenças. A atividade da CK total foi menor no grupo crioterapia, no momento 48 horas após a recuperação, em relação ao grupo controle. A LDH e a mioglobina apresentaram estabilização de seus valores no grupo crioterapia nos momentos 24 e 48 horas para LDH e 48 horas para a mioglobina. Além disso, a sensação de dor muscular aumentou em todos os momentos após a recuperação em ambos os grupos. A altura da impulsão vertical diminuiu logo após e 1 hora após a recuperação, porém o grupo crioterapia retornou aos valores pré – exercício mais rápido. A ADM de extensão ativa de joelhos do grupo controle, no momento 48 horas após a recuperação, diminuiu em relação ao momento pré – exercício, fato que não ocorreu no grupo crioterapia. Dessa forma, foi observado que a imersão em água gelada pós – exercício provoca efeitos benéficos em marcadores indiretos de dano muscular, sendo eficaz para a recuperação muscular. / Abstract: The aim of this study was to asses the effects of crytherapy immersion on markers of exercise-induced muscle damage in athletes. 15 triathletes (age: 26 }4,6, Weight: 77,4 } 4,9 kg, Height: 179,3 } 6,4 cm, %body fat: 11,5 } 1,2) at first realized a treadmill maximum effort test, for determination of maximum Heart rate and VO2max. After this, the athletes were divided into two groups: experimental (n=8) and control (n=7). Both groups were submitted to a bout of extensors and flexors knee damaging-induced eccentric exercise (4 bouts of 10 repetitions) on an isokinetic dinamometer. After exercise the athletes were randomly allocated to both groups and submitted to 15 minutes of cold water immersion (15oC) or control group (15 minutes sited). All subjects were submitted to 5 blood measures: before exercise, immediately after, 1, 24 and 48 hours after the recovery protocol. The blood samples analyzed were: leucocytes, neutrophils, CK, LDH, myoglobin and cortisol. At the same time were realized the pain sensation, jump heigth and active knee extension range of motion (ROM) sampling. A descriptive statistic (mean, standard deviation minimum and maximum values) and an analisis of variance (ANOVA) for repeated measures to compare the two groups, followed by Fisher fs Post-Hoc, was used. These analysis were made using STATISTICA 6.0 for Windows. Significant level was fixed (p.0,05). Biochemical sampling, leucocytes, neutrophils and cortisol didn ft show differences. The total CK activity was lower for the cryotherapy group, at moment 48 hours after recovery than the control group. LDH and myoglobin showed values stabilization at the cryotherapy group at the 24 and 48 moments hours for LDH and 48 hours for myoglobin. Besides that, the pain sensation increases at all moments after recovery for both groups. The vertical jump height reduced immediately and 1 hour after recovery, but the cryotherapy groups returned to pre . exercise values faster. The knee ROMs for control group, at 48 hours after recovery, decreases when compared to pre . exercise moment, this fact did not occur on cryotherapy group. It was observed that cold water immersion post exercise causes benefitial effects on indirect markers of exercise-induced muscle damage, being efficient for muscle recovery.

Blahovcová, Adéla January 2015 (has links)
Title: An observation of varying performances of triathletes based upon gender and age in the sport of Iron Distance Triathlons. Objectives: The goal of the thesis is to compare the results of the swim leg in the Ironman World Championship. We will be working with thirteen age groups compiling of 18 - 80 plus year old participants as well as both genders, male and female to gather our results. Our plan is to process results from the years 2005-2014, which is exactly 10 years or one decade. Method: Our method for gathering the results was a multiple analysis that complied a breakdown of the swim portion of an Iron Distance Triathlon for all Age Groups during those specific years. Results: After extensive research analyzing data, comparing data and studying past performances, we found that the participants times in the swim portion of Ironman Triathlon World Championships showed small significant differences over the past ten years. With minor deteriorations or improvements, swimming performances were seen at a consistent level for male and female age group 25-40. Men in the age group 18-54 showed improved outcomes over the women's same age group by 6-15%. In age groups ranging from 55- 80+, swim times increased by 15%. Overall the age groups with the most significant fluctuations in swim times was...

Řebřina, Radek January 2013 (has links)
Title: EFFECTING EXERCISE REGIMEN OF CHILDREN AT YOUNGER SCHOOL AGE An alternative form of triathlon contest as a possibility to build a positive relationship to physical activity in children Objectives: To compare motion and diet patterns and basic parameters of body constitution in selected children divided into two groups: a random population and a population of children devoted to a specific physical activity - triathlon. The aim was to focus on contests organization and management, identify its weak points and suggest a suitable alternative with the ambition to bring children closer to any of disciplines triathlon is consisting of or to triathlon itself in a longtime fashion. Methods: Body height and weight measurements, BMI calculations. Questionnaire survey. Arrangement of a triathlon contest in its new alternative way. Evaluation. Results: A group of children actively doing triathlon shows more balanced distribution of body weight in comparison with data obtained when measuring random children during PE lessons at schools where cases of obesity and underweight were found. Triathlon contest model based on adult category is not convenient for children at younger school age considering their development characteristics. Arrangement of a non-competitive triathlon contest confirmed its positive...

Příprava na nejdelší triatlonový závod (Ironmana) / Preparing for the longest triathlon - Ironman

Mika, Tomáš January 2011 (has links)
Triathlon is still a popular sport that is gaining more and morepopular. We distinguish two basic directions. Short, or if the Olympictriathlon and long, or if Ironman. In my work I examine the long triathlon. Its history, training cycle and its specifics. I myself an active rider, so this issue is very close to me. I work divided into a theoretical part, where I deal with theories and general laws of triathlon. Such as history, specifics of Ironman training and unit training cycle disciplines of triathlon course and other sub-themes, which veryclosely related to the topic. In the empirical part, I chose the method ofexperiment and research he firsthand, I attended a long distance triathlon race in the annualtraining cycle. Acquired knowledge, I capitalized on in the race and described in this thesis. This work may serve as a kind of guidance and example, and the direction of training, which can be applied when attempting to handle the challenge on behalf ofIronman. I deal with are also problems of nutrition during the race, which is out of a totaltrénovanosti organism one of the most important factors affecting performance. The workcontains several training and racing tips that I gained studying foreign literature and own racing experience.

Zikmund, Jan January 2017 (has links)
Tittle: Curve- fitting of the critical power in swimming for triathletes Objectives: Comparison of curve-fitting of the critical power at swimmers and triathletes in different performance categories. Methods: This thesis is based on a research. The research took place in laboratories FTVS UK and there was used the swimming simulator called Biokinetic for test measurements. Elite swimmers, triathletes and hobby triathletes participated in the tests. Sportsmen took part in 4 tests. The first test - 10 crawl strokes, the second test - 20 crawl strokes, the third test - 50 crawl strokes and the fourth test - 200 crawl strokes. The obtained data were worked out by using T-test and they were written into tables and charts in programs Excel and Word. There was used program PASW Statistics 18 for statistical processing. Results: It was discovered, that there were no differences in performances in tests by using Biokinetic between swimmers and triathletes. Hobby triathletes made the same performances as elite triathletes. The biggest difference in performances was at female hobby triathletes, who were worse than female elite triathletes and female swimmers. Keywords: Critical power, swimming, triathlon, Biokinetic, testing

Jordán, Daniel January 2021 (has links)
Title: Somatotype Comparison in Short Distance and Long Distance Triathlon Objectives: The goal is to determine the somatotype of triathletes competing in half ironman distance triathlons with triathletes competing in short distance triathlons. Methods: The Heath and Carter method was used for measuring the anthropometric parameters. The gained data were used in specific equations to calculate each of the three somatotype compoments. The anthropometric measurements involved participants of the Czechman Tour races. Results: By gaining appropriate anthropometric data, the average somatotype of triathletes competing in half distance events (2,1 - 4,4 - 2,9) falls into the category of ectomorphic mesomorph, whereas the somatotype of competitors in short distance events (2,1 - 4,4 - 2,9) falls into the category of mesomorphic ectomorphs. Keywords: somatotype, triathlon, body type, the Heath and Carter method

Analýza stravovacích zvyklostí v triatlonu u elitních mládežnických kategorií / Nutrition habits analysis in triathlon in elite youth categories

Follprecht, Daniel January 2021 (has links)
TITLE OF THESIS: Nutrition habits analysis in triathlon in elite youth categories. OBJECTIVES OF THESIS: The aim of this diploma thesis is to create a seven-day model nutrition plan for elite triathletes aged 15 - 18 based on an analysis of their current eating habits and anthropometric indicators together with verification of the effectiveness of nutritional recomendations after six months of compliance. METHODS USED: In our thesis we used qualitative and quantitative methods. Microsoft Excel was used for the graphical representation of anthropometric indicators and for the analysis of the current diet. Furthermore, the Sportvital-Nutrition program helped us in our work, especially in the analysis of meal plans of the monitored group. RESULTS: We found that the percentage of nutrients ingested by the monitored triathletes is on average 49 : 32 : 19 % (carbohydrates : fats : proteins), which does not correspond to the recomendations in the field of nutrition in endurance sports for youth categories. They do not even meet the correct ratio of fatty acids ingested fats according to the recommendations of the World Health Organization. Only three triathletes met the recommendations od PUFA intake, five triathletes met the recommendations for MUFA intake and no triathlete met the lower limit for SFA...
