Presença de fatores de risco dependentes ou não de esforço físico em praticantes de corrida de rua

In order to reduce the sedentarism and to improve population's health condition, many physical activity incentive programs have been stimulated. As a result, many people have adhered to street racing, but their health condition is almost always ignored. The aim of this study was to evaluate street racers' health condition, identifying the presence of cardiovascular risk factors as well as problems associated to street racing. The study case was composed by 111 racers from the town of Bauru (94 men and 17 women) aged in average 39±13 years old, who were evaluated in 4 street race competitions. The subjects answered to an anamnesis with questions about their socioeconomic status, medicine use, cardiovascular risk, physical exercise practices, and issues related to racing and injury. Weight (kg) and height (m) were measured to calculate the body mass index (BMI, kg/m²) as well as systolic and diastolic blood pressure (BP), heart rate (HR), abdominal circumference (AC), and flexibility. It could be observed that the majority of racers were Caucasian, married and belonged to social classes over C. The prevalent age was between 18 and 35 years old (42%). Among the participants, 38.7% have already undergone some kind of surgery and 13% declared having some health problem. The questionnaire pointed out that 36% had low and moderate cardiovascular risk. It could be noticed from the AC that 10% of men and 18% of women had high cardiac risk. Among the tested, 43.2% (24.3% altered and 18.9% borderline) showed high BP on the day of the test, but only 2.7% had self-declared hypertensive. In relation to injury, 36% had already had lesions of some kind, 27.5% of which had occurred in the last 8 months. 66.6% had derived from training or racing competitions and the knee was the mostly affected body part. Only 43% had professional orientation by a physical education teacher during their training and the main reasons for them to begin racing practice were...

Variação aguda da frequência cardíaca durante série de hipertrofia para grupo flexor e extensor do cotovelo

Currently individuals are affected by a routine busy and they don't have time for physical activity, highlighting the sedentary lifestyle, a risk factor for cardiovascular diseases. For this reason, it focuses too much on cardiovascular diseases and the importance of physical practice. With the largest divulgation and variety of physical activities, activities that were not as practiced became popular, as is the case of resistive exercise. Much is said of the influence of resistance exercise in physical strength, in muscle development and in the quest for a more defined body. However, studies have shown beneficial contributions of resistance exercise on the cardiovascular system. During the physical effort, some changes occur in the body in order to meet the increased demand for oxygen. Among them is the increase in heart rate (HR), which varies with the intensity of effort. Thus, this research sought to contribute with an analysis of the HR behavior before, during and after 3 sets of hypertrophy, as far for the flexor group of the elbow as to the extensor group. It was observed that, although the HR has increased in the course of the series, the variations of HR were not significant between the flexor group and extensor group of the elbow joint. Also were not significant the differences between the variations of the HR from the 1ª to the 2ª series between the flexor group and extensor group, as well as to the variations from the 2ª to the 3ª series

Efeito da utilização do coringa no treinamento em campo reduzido em jogadores de futebol universitário

Soccer is the most popular sport in Brazil and one of the most popular in the world. Within this context, the practice of university soccer has increased the number of practitioners. A methodology widely used in the training of high performance teams are games reduced field ( JCR). The objective of this study was to evaluate the intensity of physical effort of football players during a small side game, 4x4, check the correlation between [La], HR PSE and the players and the floater influence on the intensity of the small side game. We analyzed eight players of UNESP in Bauru mean age 21.2+1.5 years, weight 75.8+11.6 kg, height 1.77±8cm, body fat percentage 12.3+5.5%, VO2max 37.1 ml/kg/min. The training was performed in 4 x 6 min with an interval of between one minute for recovery. The [La] and PSE were collected between the second and third time and after the end of training, the HR was measured every five seconds throughout the training through the RS400 heart rate monitor. A training session player floater participation (4x4+1) and the other not (4x4). The results presented showed no correlation with the HR [La] and PSE. HR significantly different, being 157+10 in the game 4x4+1 and 146+13 in the game 4x4. The percentage of HRmax in the game with floater was 81.3% and 75.7% in the game without. The players were most of the time in a higher intensity in the JCR with a floater, 37.8% of playing time over 85% HRmax, and 22.5% of playing time over 85% of HRmax in the JCR without floater, demonstrating that the use of a floater player made the game more intense and efficient to increase the intensity of the game

O nível de esforço físico durante o treinamento coletivo no Futsal na categoria Sub 13

Futsal is one of the most popular sports in Brazil, played on five continents, in hundreds of countries, but is still a poorly studied sports science. Among the types of training used in the preparation of soccer players, the collective training is one of the most used because it is a simulation game. The application of the training load is often made in large quantities (volume) with exercise duration and intensity greater than what the athlete can handle. Thus, this study aimed to evaluate the intensity of physical exertion of futsal players of basic category during collective training. We evaluated twenty (N=20) soccer players from two teams with different levels of training. There were ten players on a team federated (FED) and ten players on a team for a project extension (EXT). Samples were collected at the respective locations of training. An evaluation of anthropometric and during collective training heart rate was measured and at the end of each training time blood samples were collected for analysis of blood lactate concentration and perceived exertion of the players. There was significant difference between the two teams only in fat percentage (FED=13,4 e EXT=21,2). The average heart rate during training was 174 ± 12.2 bpm, which corresponds to 84% HRmax. There was significant difference between heart rate and the percentage of HRmax in the two parts of training in both teams. The Federated team players remained most of the time in more intense intensity zone (above 85% HRmax), while the EXT players were most of the time zone of moderate intensity (65-85% HRmax). The rating of perceived exertion (FED=3,5 e EXT=3,2) and blood lactate concentration (FED=2.4 mmol/L and EXT=2.9 mmol/L) showed no significant difference between the two teams and between the two times. During training there was a significant correlation (p= 0.71) between heart rate and lactate concentration. The collective training showed an intensity that is supposed to be...

Anestesia peribulbar para enucleação em um felino: relato de caso

Foi atendido no Hospital Veterinário “Luiz Quintiliano de Oliveira”, o felino Nick, SRD, de quatro meses de idade, pesando 700 gramas, com histórico de trauma por arranhadura em bulbo ocular esquerdo. Ao exame físico específico, evidenciou-se úlcera profunda e prolapso de íris, sendo então indicada a enucleação. Ao exame físico geral, observou-se freqüência cardíaca (FC) de 160 batimentos.min-1, frequência respiratória (f) de 80 movimentos.min-1, tempo de preenchimento capilar menor do que dois segundos, temperatura retal (TR) de 39,2oC e mucosas normocoradas. Como medicação pré-anestésica, empregou-se acepromazina (0,04 mg.kg-1) e metadona (0,3 mg.kg-1), administradas pela via intramuscular. A veia femoral esquerda foi cateterizada com cateter 24G para administração de Ringer com Lactato de sódio (10 mL.kg-1.h- 1 ). A indução foi realizada por máscara facial tendo-se como agente o isofluorano em fluxo diluente de 100 mL.kg-1.min-1 de oxigênio a 100%, seguida de intubação orotraqueal com sonda n o 2,5 sem cuff. Seguiu-se a manutenção anestésica com a mesma mistura da indução, administrada por meio de circuito anestésico sem reinalação de gases, do tipo Baraka, mantendose o paciente sob ventilação assistida. Ato contínuo, realizou-se a técnica anestésica peribulbar de punção única inferior, utilizando-se lidocaína 2% com vasoconstritor (3mg.kg-1) associada a bupivacaína 0,5% sem vasoconstritor (0,8mg.kg-1), perfazendo um volume total de 0,3ml.kg-1 . Uma agulha 13x4,5 foi introduzida em todo o seu comprimento com o bisel voltado para a órbita, no terço lateral do fórnice conjuntival inferior da órbita esquerda, administrando-se a associação dos agentes anestésicos locais, seguida de compressão manual da área para facilitar a difusão dos mesmos. Durante o procedimento anestésico, realizou-se a monitoração da FC, f, pressão arterial sistólica (PAS), TR e saturação periférica da hemoglobina (SpO2). O tempo total de anestesia e cirurgia foi de 30 e 20 minutos, respectivamente, e a SpO2, concentração de isofluorano e TR mantiveram-se em 99±1%, 1,7±0,8% e 37,4±1,5oC, respectivamente. O plano anestésico manteve-se estável, sem a necessidade de resgate analgésico. Não houve a ocorrência de reflexo óculo-cardíaco (ROC) frente à manipulação do nervo óptico, o que pode ser atribuída provavelmente ao bloqueio peribulbar. A anestesia regional é frequentemente empregada para cirurgias oftálmicas em humanos, como a facoemulsificação, sendo que o manejo anestésico pode contribuir para o sucesso do procedimento. Pode-se concluir que, também na espécie felina, o bloqueio peribulbar pode ser uma boa alternativa para a realização de protocolos de anestesia balanceada para procedimentos oftálmicos.
