Title: The physical load on the body as a factor influencing perceptual cognitive functions. Objective: The aim of this study is to determine the relationship between the size of the physical load and the visual-motor response time and the accuracy of the decision-making by junior soccer players. Methods: The fourty two respondents (in an average age of 19 ± 1.2 years) participated in the study. It was the single factor quasiexperimental, multilevel and intragroup in which we tried to reveal the causal relationship between the visual-motor response time and the accuracy of the decision-making depending on the size of the previous physical load. We proposed a diagnostic instrument containing the video of the offensive game situations which would allow simultaneous evaluation of the visual-motor response time (using Dartfish software program) and the accuracy of the decision-making (through experts assessment). Results and discussion: The diagnostic instrument contains sixteen video clips of the offensive game situations according to the highest degree of conformity of the panelists. I used polychoric correlation matrix to express dependencies between each game situation within each group comprising four video clips of the offensive game situations. The results of the matrix (range -0.437 to 0.306)...

Each and every day we have to face a serious problem - ways of healthy eating and drinking, how tospend our free time. First part belongs to a theoretical knowledge. Also you can find there information about each elements of food, nutritious elements, advises how to rebuilt healthy menu up and latest trends in healthy eating. Second part deals with the attempt to create a six months interventional programme of football team players of Slavoj Česky Krumlov B, playing the South Bohemia 1st B Division. I set up the programme which should give a guidelines to players how to protect themselves from unhealthy life style by teaching them how to eat healthily, to remove muscles dysbalances, to improve self-perception and by using The Method of unfinished sentences to help with value levels. As a check sample I have chosen the Spartak Kaplice B players, playing the same division. There hasn't been pursuated the interventional programme on these players.\\

Objetivos: descrever os valores de freqüência cardíaca (FC) e os níveis das concentrações de lactato [La] sanguíneo, verificar o comportamento da curva da freqüência cardíaca dos dançarinos cadeirantes durante uma competição de DECR, comparar a carga física entre as rodadas e a resposta cardíaca específica entre as danças Samba, Rumba e Jive. E por último, comparar a FCMpico (freqüência cardíaca máxima de pico) obtida pelos atletas na competição, frente a FCMcal (freqüência cardíaca máxima calculada) prevista para a idade. Métodos: Participaram deste estudo 9 (nove) atletas cadeirantes com deficiência (quatro com lesão medular, três com seqüela de poliomielite e um com espinha bífida), sendo quatro homens e cinco mulheres, com média de 34,6±10,5 anos de idade, 53,7±9 kg de massa corporal, 4,1±2,4 anos de prática e que competiram durante o VII Campeonato Brasileiro de DECR. Para o registro da FC utilizou-se o conjunto de cardiofrequencímetros durante toda a competição, já para a medidas das [La] foram realizadas cinco a representação gráfica da curva da FC demonstrou-se compatível com atividade física intermitente, a média da carga física das rodadas foi de 89,9%FCpico não havendo diferença significativa entre as mesmas. Em relação aos estilos de dança, houve diferença significativa de intensidade, sendo o Jive mais intenso (p≥0,05) do que o Samba e a Rumba não havendo diferença entre essas duas. A média da FCMpico (189 bpm) foi maior (p≥0,05) do que a média da FCMcal (165,3 bpm). Em relação aos níveis de [La] a maioria dos atletas avaliados atingiu valores de pico entre 4,2 e 6,2 mM. Conclusão: a DECR é uma modalidade com características intermitentes, a média de intensidade durante as rodadas é compatível com uma atividade de alta intensidade e muito provavelmente os atletas atingem a FCM durante a competição. / The Wheelchair Sport Dance (WSD) it is an adapted sport modality of the ballroom dance practiced in Brazil since 2001, however, no there are studies that approach the physiologic answers to the effort that the athletes/dancers submit in a competition of WSD. Purpose: to describe the values of heart rate (HR) and the levels of the lactate concentrations [La] sanguine, to verify the behavior of the curve of the HR of the dancers wheelchairs during a competition of WSD, to compare the physical load between the rounds and the specific heart answer among the dances Samba, Rumba and Jive. It is last, to compare HRpeak (heart rate peak maxim) obtained by the athletes in the competition, front HRMcal (maximum heart rate calculated) foreseen for the age. Methods: They participated in this study 9 (nine) athletes wheelchairs with disabled (four with spinal cord injury, three with poliomyelitis sequel and one with bifid spine), being four men and five women, with average 34,6±10,5 years , 53,7±9 kg of body mass, 4,1±2,4 years of practice and that competed during the VII Brazilian Championship of WSD. For the registration of HR the Polar Team Systeam was used during all the competition, already for to measured of the [La] five were accomplished. The graphic representation of the curve of HR was demonstrated compatible with intermittent physical activity, the average of the physical load of the rounds was of 89,9%HRpeak not having significant difference among the same ones. In relation to the dance styles, there was significant difference of intensity, being most intense Jive than the Samba and the Rumba not having difference among those two. The average of HRMpeak (189 bpm) it was larger (p?0,05) than the average of HRMcal (165,3 bpm). In relation to the levels of [La] most of the appraised athletes reached pick values between 4,2 and 6,2 mM. Conclusion: WSD is a modality with intermittent characteristics, the average intensity during the rounds is compatible with an activity of high intensity and very probably the athletes reach HRMduring the competition.
