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...

Avaliação do perfil antropométrico e de força de jovens jogadores de polo-aquático

The present study aimed to analyze the performance of 'boost' among water polo athletes. Twelve athletes (13,9  1,08 years, 169,0  6,0 cm and 59,5  13,5 kg of bodyweight) were under went to anthropometric assessment, body composition and maximum concentric strength of lower limbs. The jump test in the water was done by 'boost' and scaled to jump height. According to the results of strength (Leg Press 45: 157,08  43,30 kg Leg Extension: 72,08  12,86 kg), anthropometry (arm circumf.: 26,04  3,25 cm, thigh circumf.: 50,47  7,65 cm, sholder circumf.: 95,97  8,00 cm, elbow diam.: 4,74  0,51 cm, wrist diam.: 3,21  0,34 cm, knee diam.: 7,89  0,58 cm, biacromial diam.: 37,49  3,81 cm and bi-iliac diam.: 25,43  4,34 cm) and body composition (BMI: 20,74  4,00 kg / m² and% fat: 8,45  4,28), only stature showed a linear correlation (r= 0,595) to the values of vertical jump (height: 47,80  4,35 cm) performance. This anthropometric variable was one able to influence the height of performance by modifying it self, perhaps by maturity. However maturity may be an implicity feature of performance, since force is a concerned effect of the growth. Otherwise technique could play a mains role to the performance of the 'boost'. It can be conclude that possibly is advantageous for water polo athlete be higher and more mature for the realization of 'boost', and the training directed for the technique, but is necessary muscle fitness for the holder

Comparação entre a recuperação da economia de corrida e força muscular medida por diferentes métodos após o dano muscular

The goal of the present study was to investigate possible differences towards strenght recovery measured by different methods and running economy (RE), after one session of downhill running (DR), in order to induce muscle damage (MD). Our hypothesis is that the strenght recovery measured by jumps is more alike RE markers, due to the measures' specificity. Ten male subjects, ages 18 to 30, apparently healthy, without any experience with strenght training at least 6 months before the tests took place in this study. After going to the lab twice (to familiarize themselves with the protocols, and determine their maximum oxygen consumption/running speeds), they went to the lab five times in the following week, in order to collect all the variables before, immediately after, and 24, 48, 72 and 96 hours in. The variables obtained were: stride frequency (SF), stride lenght (SL), oxygen volume (VO2), carbon dioxide volume (VCO2), ventilation (VE), lactate blood concentration ([Lac]), isometric peak torque (IPT), subjective pain perception (SPP), effort perception (EP), medial-portion circumference (CIR), knee movement extent (EXT), torque development rate (TDR), counter movement jump and squat jump height (HCM and HS), strenght development rate of both jumps (SDCM and SDS), and maximum soil strenght reaction (SRCM and SRS). Changes over time in all variables were verified by one way variancy analysis. Differences between the strenght measures were verified by two way variancy analysis. When significant effects were verified, Tuckey's post-hoc were applied. The significancy level taken on this study was p < 0,05. Of all indirect muscle damage markers, IPT, SPP and TDR were the only ones in which ocurred significant changes. We couldn't find the moments where this happened for TDR with the post-hoc used. On RE markers, VO2, [Lac] and VE suffered significant effects over time. About the jumps variables, only SDCM and HCM presented significant...

Influência do método de avaliação no diagnóstico da dor muscular de início tardio após corrida em declive

Several methods are used towards delayed onset muscle soreness appraisal. This study's goal was to investigate, amongst three commonly adopted methods, which one would be the most effective (the one that shows higher values) in the quantification of this phenomenon. 10 male subjects, of age 22.8 ± 3.1 years old, weight 80 ± 12.4 kg, height 174 ± 0.07 cm, without recent experience with strength training (lower limbs) and/or running took place in this study. All subjects carried out a muscle damage induction protocol, which consisted of 30 minute downhill running (-16% or -9.09º) at 80% speed compared to their maximum oxygen consumption. Muscle damage determinants such as isometric peak torque, knee joint range of motion and circumference of the medial portion of the thight were measured before, during, 24, 48, 72 and 96 hours after downhill running. The subjective pain perception was measured simultaneously with the other determinants through three different tests: sitting on and getting up of a chair; climbing and descending from a 45cm step; and self thigh palpation. After going through all subjective pain perception tests, the subjects filled out a visual analog scale with their perception of pain. Muscle damage changes over time were compared through variance analysis (ANOVA) one way for repeated measures. Subjective pain perception values obtained in all three different tests were compared through two way ANOVAs for repeated numbers. The significance level adopted in this study was z ≤ 0.05. The results showed that the step test was the on which better evaluated the delayed onset muscle soreness. No significant differences were found through the ADM and CIR recovery markers. Downhil running determined reduced of PTI (~22.4%). Significant links between pain were obtained for both subjective pain perception tests starting at 24 and 48 hours, where the highest registered average happened in the step test after 48h, with high...

Perfil cinético do movimento pirouette do ballet clássico em bailarinas experientes e não experientes

A dança é uma das formas de expressão artística mais antiga da história da humanidade. O movimento da dança em foco no presente estudo foi a pirouette do ballet clássico. Tal movimento é caracterizado por um ou mais giros em torno do seu próprio eixo, executado sobre uma perna seja em meia ponta ou ponta completa, enquanto a outra está flexionada, com o pé abaixo do joelho da perna de apoio. O presente estudo consistiu em examinar o perfil cinético do movimento pirouette de bailarinas experientes e não experientes no Ballet Clássico. A hipótese é de que as variáveis relativas à força para produzir o giro influencie na realização do pirouette. As participantes do estudo foram convidadas a realizar o pirouette sobre uma plataforma de força. Os resultados do presente estudo demonstraram que as bailarinas experientes aplicam maior força para iniciar o giro em relação às participantes não experientes. Em conjunto, os resultados do presente estudo sugerem que a força vertical aplicada para iniciar o giro, a qual denominamos impulso inicial, parece ser determinante para a boa performance no movimento pirouette da bailarina. Os resultados do presente estudo oferece uma importante contribuição aos técnicos e professores de dança de forma a valorizar questões de controle motor e postural no processo ensino-aprendizagem do pirouette

Lombalgia equina: diagnóstico e tratamento

Low back pain is considered a major cause of lameness and performance decay, but identify the location of the lesions and quantify the intensity of pain is difficult because often the most obvious clinical sign, in some cases, is not the pain itself, but, low athletic performance. The diagnosis and treatment of this disease are associated with a high cost and have a strong impact on the equine industry, since it results in direct economic losses. The diagnosis of low back pain is made through physical examination and additional tests, including radiography, ultrasound, thermography and blockades. Major injuries causing back pain in horses is the contact or overlap of the spinous processes, supraspinous desmitis, osteoarthritis of the articular processes, vertebral body lesions and myositis. Therapeutic measures used in the treatment of these diseases are systemic inflammatory steroid, local infiltration, acupuncture, chiropractic, physical therapy, changes in training and surgeries.
