The variables evaluated were lactate anaerobic threshold (AT); blood lactate concentration (BLC) at the overload of 5% body mass (bm) during the test for AT estimation and muscle and liver glycogen concentrations. Glucose metabolism in vitro, in isolated sóleous muscle incubated in presence of insulin (lOOmU/lOOmL), was also evaluated, by measuring the glicose uptake, using [3H] 2-deoxyglicose (2-DO = 0,5 uCimL1) as tracer, as well as, glycogen synthesis, lactate production and glucose oxidation from [U' 4C] glucose (0,25 tCi mLj. The statistical methods included Anova one-way, with the significance level set at 5%. In one experiment, four groups of male Wistar were compared: sedentary (SED); continuous training with overload of 5% bm (CT5); interval training with 7,5% bm, work:pause of 4 min:lmin30s (IT-7,5); Interval training with overlod of 10% mc, work:pause of 30s:30s (IT-1O). The groups of exercise-ttrained rats exercised 6Omini'day. In another experiment, a SED group, a continuous training (CT5) and a periosdised training (basic, specific and taper period), with volume intensity, aerobic and anaerobic alternation of the stimulus (PT) were formed. After a 3-4 weeks adaptation period, in both experiments, the trained groups maintained training frequency of 5 days/week, during 5 weeks. In each experiment, the training overload was quantified (% bm time of exercise in the training session) and the total work was the same in all groups. In the first experiment there was no significant difference in AT among the groups. CT5 group presented lower BLC at 5% bm than SED (CT5 = -21,8; 1T7,5 e ITIO = -12,7%) groups, The animal of the [T-7,5 group... (Complete abstract, click electronic address below)

The athletes were submitted to blood tests for determination of biochemical markers (cretine kinase, creatinin, urea, cortisol, testosterone and ratio cortisol - testosterone) and hematological (hemoglobin, hematocrit, erythrocyte, leucocytes, lymphocytes, monocytes, segmented, eosinofils, basophiles and plasmocites). Invasive tests were accomplished (anaerobic threshold, anaerobic alactic index and 30-s maximum swimming attained power) and non-invasive tests (critical speed and anaerobic work capacity), and psychological test (Profile of Mood States). To show the results, the participants were divided in three groups, men (M), women (W) and all (MW). The statistical treatment included percentis analysis for all the parameters, in absolute values (deltas in relation to the base line), which were elaborated starting from the results obtained in the beginning of the training (T1). Those were used for athletes training (TR) or overtraining (ST) determination. The results obtained during the training period were treated by one way variance analysis (ANOVA), followed for Newman Keuls post-hoc test, when necessary.

Výběr a trénink fotbalových talentů / Selection and training of football talents

Poslušný, Daniel January 2011 (has links)
In my thesis I deal with issues of selection and training of talents in the youth football teams 1.FK Pribram. I play football from early childhood, so I can use my experiences in problematic selection and in training of football talents. Theoretical part I divided into eight chapters. The first chapter describes the history of football. The second chapter describes the history of football in our country. The third chapter deals with the characteristics of the current concept of football. Follows the fourth chapter, where are graphs of football competitions from the ages preparatory to adult men's category. In the fifth chapter is detailed content of the performance of an individual, game, goalie and the coach's personality and his work. Chapter six is devoted mainly characteristics of age periods from preparatory to older pupils. The penultimate chapter contains objectives, content and output of training groups from each age. Final eighth chapter describes talents and the selection of talents. Researching part is created by my own research in selecting and training talents. In my work I set hypotheses and results of research either confirm or refute them. Part of my job is also an empirical investigation, where I used the method of questionnaire and structured interview methods, including...

Fast science : a history of training theory and methods for elite runners through 1975

Bourne, Nicholas David, 1965- 04 September 2012 (has links)
This dissertation examines the history of the application of science to the training of elite runners through 1975. In particular, it details the changes that occurred in the ruling theories of training within the framework of what Thomas Kuhn, author of The Structure of Scientific Revolutions refers to as a “paradigm shift.” The quest for the origins of training began in ancient Greece where the earliest written histories of athletics were recorded. There, according to the sophist Philostratus, a rudimentary form of periodization (a process of structuring training into phases) was born. Examination of eighteenth and the bulk of nineteenth century training practices revealed little difference in the training of horses, fighting cocks, greyhounds, pugilists (boxers), and runners. In the lead up to WWI, training could be classified as “light,” where athletes stayed competitive with very little training. Athletic training between WWI and WWII was characterized by the advent of “moderate” training loads and the introduction of innovative training methods--fartlek and interval training. Arthur Lydiard’s recommendations of preliminary marathon training for distance runners (800- 10,000 meters) in the late 1950s, along with the training of Emil Zátopek, Peter Snell,and Jim Ryun, epitomized a transition from moderate to “heavy” training loads thatoccurred between 1945 and 1975. Meanwhile, other eminent coaches such as Payton Jordan of Stanford University and William Bowerman of the University of Oregon offered balance to the heavy volume training approach by emphasizing quality over quantity. Following WWII, in the battle for world ideological supremacy, the Soviet Union utilized sport as a political tool to demonstrate the superiority of its communist system. Integral to achieving the best sporting results was the application of “cutting edge” sport science and the advent of modern-day periodization. The first detailed English-language overview of Professor Lev Pavlovich Matveyev’s groundbreaking theory of periodization by Frank Dick of Great Britain in 1975 caused a major shift in the paradigm of planning an athlete’s training--so much so, that by the turn of the twenty-first century, periodization formed the foundation of most modern coaching theory and practice and the basis of every serious athlete’s training. / text
