Aptidão aeróbia e amplitude dos domínios de intensidade de exercício no ciclismo

INTRODUÇÃO: A determinação dos domínios de intensidade de exercício tem importantes implicações na prescrição do treino aeróbio e na elaboração de delineamentos experimentais. OBJETIVO: Analisar os efeitos do nível de aptidão aeróbia sobre a amplitude dos domínios de intensidade de exercício durante o ciclismo. MÉTODOS: Doze ciclistas (CIC), 11 corredores (COR) e oito indivíduos não treinados (NT) foram submetidos aos seguintes protocolos em diferentes dias: 1) teste progressivo para determinação do limiar de lactato (LL), consumo máximo de oxigênio (VO2máx) e sua respectiva intensidade (IVO2máx); 2) três testes de carga constante até a exaustão a 95, 100 e 110% IVO2máx para a determinação da potência crítica (PC); 3) testes até a exaustão para determinar a intensidade superior do domínio severo (Isup). As amplitudes dos domínios (moderado < LL; LL > pesado < PC; PC > severo < Isup) foram expressas como percentual da Isup (VO2). RESULTADOS: A amplitude do domínio moderado foi similar entre CIC (52 ± 8%) e COR (47 ± 4%) e significantemente maior no CIC em relação ao NT (41 ± 7%). O domínio pesado foi significantemente menor no CIC (17 ± 6%) em relação ao COR (27 ± 6%) e NT (27 ± 9%). Em relação ao domínio severo não foram encontradas diferenças significantes entre os CIC (31 ± 7%), COR (26 ± 5%) e NT (31 ± 7%). CONCLUSÃO: O domínio pesado de exercício é mais sensível a mudanças determinadas pelo nível de aptidão aeróbia, existindo a necessidade de que se atenda ao princípio da especificidade do movimento, quando se pretende obter um elevado grau de adaptação fisiológica.

A relação entre tabagismo e habilidades sociais: uma revisão da literatura

The literature suggests an association between drug use and addiction and the repertoire of social skills of the individual. However, there are still relatively few studies focusing specifically on the relationship between smoking and social skills. Moreover, Brazilian studies on the subject are scarce. This paper presents a review of the literature about smoking and social skills, emphasizing the theoretical underpinning research, as well as the main data obtained so far. One of the most investigated issues is the relationship between assertiveness and smoking. It is assumed that the lack of assertiveness and in particular the ability to refuse the supply of drugs and / or peer pressure to consumption can be a risk factor for smoking initiation, especially in adolescents. However, the literature on this issue is still controversial. It is assumed that further studies to elucidate these associations could contribute to prevention programs and intervention for tobacco use, using social skills training as a strategy.

Desempenho de escolares com dislexia: programas de intervenção metalinguistico e de leitura

Dyslexia is specific learning disabilities, of neurological origin, resulted from a phonological deficit of language. This study aims to verify the performance of students with dyslexia in phonological intervention program, reading program, and phonological and reading remediation program in students with dyslexia. The participants of this study were 60 students who were divided as follows: GI (ten students with dyslexia submitted to phonological remediation program and ten students with dyslexia not submitted to phonological remediation program), GII (ten students with dyslexia submitted to reading program and ten students with dyslexia not submitted to reading program), GIII (ten students with dyslexia submitted to phonological and reading program and ten students with dyslexia not submitted to phonological and reading program). The phonological and reading remediation was applied in three phases: pretest, training, post-testing. The results showed significant statistical difference between two evaluation moments, revealed better performance in the cognitive-linguistic skills in post-test situation comparing to the pretest, showing the efficacy of the three remediation programs for students with dyslexia. The better performance of the students with dyslexia submitted to the remediation programs shows the necessity of phonological instruction or phonological instruction with reading to be offered in the literacy context, once this will help students to develop cognitive-linguistic skills to learn the alphabetic basis of the Brazilian Portuguese writing system.

Caracterização das lesões desportivas em atletas de Tênis de Mesa

Introduction: The table tennis is characterized by requiring of the athletes intense body movement. The gestures performed by athletes require continuous postural changes, in cases of any sway in body structures may produce postural changes or initiate processes of injuries. Objective: The aim of this study was to characterize the table tennis lesions. Method: Were evaluated 31 athletes (26 males and fi ve females) with mean age 22.35±6.67 years. The subjects were interviewed with the Reported Morbidity Inquires retroactive to the 2009 season. It was used techniques of descriptive and analytical statistics. Results: The largest number of injuries was muscular (74.35%), on the shoulder (43.58%) during the movement of top spin (33.33%) in the specifi c training phase (64.1%) with symptomatic return to the activities (69.23%). Conclusion: The weekly training workload infl uences the number of lesions.

Memória, envelhecimento e qualidade de vida: a perspectiva da psicologia cognitiva

The concern with aging has increased in recent decades throughout the world, before the gradual increase in life expectancy of the population. Researchers have been developing a diverse in nature, in order to subsidize the activities of professionals in the field of Gerontology to promote autonomy, preservation of cognitive functions and thus contribute to healthy aging. This article presents a review of the literature on memory and aging from the perspective of cognitive psychology. The bibliography contains studies focusing on different subjects, in this sense. A significant number of works have been undertaken in order to investigate mechanisms and benefits of training on memory in healthy elderly and / or cognitive improvement. A concept that deserves attention in such studies is the study of aspects of meta-memory. However, there are still relatively few controlled studies on the subject.

Avaliação do estado emocional associado à catalepsia causada pela administração intraperitoneal de haloperidol

Haloperidol is a dopamine receptor antagonist used to treat schizophrenia. When systemically administered in rodents, haloperidol induces catalepsy, a state of immobility very similar to that seen in Parkinson's disease. It is known that many of Parkinson's disease symptoms are dependent on the emotional state since patients are still able to respond to external triggers such as loud noise or visual signaling. Recent data highlighted the importance of glutamatergic neurotransmission in the inferior colliculus (IC) on the cataleptic state induced by haloperidol in rats. Given the importance of IC in the brain aversion system and its connections to motor pathways, and based on the clinical reports of the emotional influence on the motor aspect of Parkinson's disease, the objective of the present study was to evaluate the emotional aspect related to catalepsy induced by intraperitoneal administration of haloperidol. To this end, we analysed ultrasonic vocalizations (UVs) of 22 kHz (indicative of aversion) in rats during the tests of catalepsy, open field and contextual conditioned fear. Systemic administration of haloperidol affected the motor activity, inducing catalepsy and decreasing exploratory activity in the open field. There were no UVs of 22 kHz resulting from treatment with haloperidol in catalepsy or open field tests. In the contextual conditioned fear test, haloperidol increased freezing when administered before the test, but decreased freezing on test day when administered before training. In this same test, haloperidol decreased the UVs on the day it was administered (training or test). The catalepsy induced by systemic administration of haloperidol seems to have also affected the motor aspect of UVs. In this way, it was not possible to clarify the existence of an aversive emotional state associated haloperidol induced catalepsy

Arquitetura esportiva e a criação de um estádio: construção de um estádio de futebol para o S.C. Corinthians Paulista

O Corinthians é o clube de maior torcida no Estado de São Paulo, o segundo maior no Brasil e ainda não possui um estádio adequado para grandes competições. Localizado na região do Tatuapé, na capital paulista, o Parque São Jorge e o Estádio Alfredo Schürig são o que o time conta como espaço para treino. Suas partidas em casa são disputadas no Estádio do Morumbi ou do Pacaembu. No ano de seu centenário, entre muitos projetos já existentes, apresenta-se um novo conceito: um estádio para o clube e que também atenda as exigências de uma competição mundial, a Copa. A Copa do Mundo de Futebol atrai olhos de todos os continentes. É o evento de maior audiência e o segundo maior em termos de arrecadação (perdendo apenas para o Super Bowl). Para isso são necessárias que as exigências determinadas pela FIFA (Federação Internacional de Futebol Associado) sejam atendidas. Com todo o custo que envolve a construção e manutenção de um estádio, foram estudadas maneiras de gerenciá-lo para que a arrecadação seja suficiente para sua manutenção. Espera-se que a arquitetura possa colaborar com soluções práticas para esse desafio

Validação do instrumento de avaliação do jogador de futebol em situação de jogo

In the literature, it is possible to find a large number of studies directed toward athletic training in the physical, technical and tactical aspects of the Soccer game. In the other side, we are able to attest that there exists few instruments in the sport area of studies on evaluation of the athlete, in specific, rare are the instruments for assessment that takes into consideration the game situation. The most important aspect of an instrument of assessment is its validity. The present study has the objective to validate the “Instrument for Assessment of the Soccer Player” (IASP), proposed by Gama (2003). For the process of validation, participated nine university students, volunteers, four women and five men. The evaluators had a training period for acquaintance with the instrument and they analyzed, in individual basis, soccer games registered in video. This procedure was done via a 29 inches TV set, a DVD device and a voice recorder. Tests of reliability and objectivity were applied in order to measure intra and between observers consistency. As for the objectivity analysis, the results for each one of the soccer motor action with the ball in a game situation showed high correlation between possible score and obtained score. However these data did not allow for the validation of the IASP instrument as the criterion applied to the analyzed actions were different between observers even when of the observation of the same player in the same game. This problem was detected also in the evaluation of reliability. However, the present study was capable to point out inconsistencies within the Instrument for Assesment of the Soccer Player (IASP) so that after the needed changes being made, another validation will be done

Efeitos do treinamento isocinético e isométrico sobre a taxa de desenvolvimento de força máxima

The objective of the present study was to compare the effects of a high speed isokinetic training (180°.s-1) and an isometric training (75°) on the maximum rate of force development (RFDmax) measured in the isokinetic and isometric modes. Twenty seven male non active subjects participated of this study (Mean + SD = body mass 78.6 + 14.1 kg; stature 175.1 + 8.9 cm; age 22.6 + 3.8 years). They were randomly divided into three groups: Control (GC); Isokinetic training (GISOC) and; Isometric training (GISOM). The subjects were submitted in different days to the following pre training protocols: 1) Familiarization to the isokinetic dynamometer tests; 2) Five maximum concentric isokinetic contractions of the knee extensors (180°.s-1) to access the maximum concentric torque (TMC) and the concentric RFDmax; 3) Two maximum isometric contractions of the knee extensors (75°) to access the maximum isometric torque (TMI) and the isometric RFDmax. The same tests were repeated after the training period, but without the familiarization session. Eighteen training sessions were performed (3 times per week). The GISOC performed the entire training whit concentric isokinetic contractions whit the speed of 180°.s-1. The GISOM performed the entire training whit isometric contractions whit the angle between the thigh end the leg being 75° (0° = full knee extension). TMI, TMC, concentric RFDmax, isometric RFDmax values of the GC was not different between pre and post training. GISOM increased only the TMI and the GSIOC increased the TMC, concentric RFDmax and isometric RFDmax. Furthermore, the GISOC had a higher percentage increase of the isometric RFDmax than the isokinetic RFDmax. Based on these results, it is possible to conclude that the increase in maximum strength corresponded to the training specificity theory, unlike to the RFDmax. Thus the use of isometric contraction ...(Complete abstract click electronic access below)
