Among the motor skills required by a football player, we highlight the ability of aerobic endurance which is important not only during the match but also after it, in the period referring to the players’ recovery. In order to measure the maximal aerobic power (VO2max) might be used field tests (indirect) estimating the VO2max. In this case, these tests are cost effective and provide conditions more close to the sport specificity. This study is aimed to compare the results of VO2max football players by applying two indirect tests of distinct field. In this sense, the continuous run of 3,200 meters and the physical fitness test multi-stage (Yo-Yo test level 1) were employed. There were 25 athletes from a volunteer football team (category juniors), which were evaluated in both protocols, with a minimum interval of 48 hours between the sessions. No significant differences (p>0.05) between average values of VO2max for the two protocols were observed, once the continuous run test and the Yo-Yo one presented values of 58.13 ± 3.40 ml / kg and 55.57 ± 4.07 ml / kg, respectively. These results are in agreement with other studies reported in literature involving football players, both junior and professionals ones. In addition, we also found high correlations (R= 0.76) between average values of VO2max obtained in both indirect tests, suggesting that both might be useful in order to estimate the VO2max of junior football players. Key words: Oxygen consumption, Indirect tests, Football players.

Introduction: Works of different authors has been shown that, an increase in the concentration of serotonin (5-HT) in the brain during intense and long-term physical exercise, is directly related with a harm in the function of the Central Nervous System (CNS), with corresponding development of the fatigue and consequence decrease of the performance. Materials and methods: Ten rats Wistar was submitted the run-sessions until the exhaustion in treadmill. The experimental protocol consisted in the evaluation of the range run-time of the animals until the exhaustion, divides in three weekly sessions in alternates days. The animals were treated, during seven days, with agonist drug 5-HT, fluoxetine, (10mg/kg/day) dissolved in physiologic solution (NaCl 0,9%) injected intraperitoneally (i.p.). Results: It was observed that the average run time of the animals to exhaustion increased significantly. Conclusion: The present study suggest that the chronicle administration (12 days) of fluoxetine in the dose of 10 mg/kg/day (i.p.) increase substantially the run-time until the exhaustion in rats submitted the exercises in treadmill. Key words: Central fatigue, Serotonin, Exercise.

Physical exercise brings several benefits to its practitioner. Exercise modulates several organic reactions; however the effects of the physical exercise on the level and metabolism of cortisol are not completely clear. Objective: To review the literature on the effects of cortisol secretion in exercise and metabolism. Literature review: It has been shown in scientific literature that cortisol acts as a physiological antagonist of insulin, and promotes carbohydrates, lipids and proteins cleavage thus mobilizing energetic storages. It increases glicemia and the liver glycogen production. Since cortisol stimulates proteolysis, the cortisol increasing could lead to muscular atrophy and strength decreases, with negative consequences to the sportive performance. The skeletal muscle action of cortisol is ambiguous: it contributes to carbohydrate and muscle loss, but simultaneously, without cortisol the skeletal and cardiac muscle contraction is reduced. This effect could be due to the induction of mediators or receptor synthesis, such as acetylcholine and -adrenergic receptor, constitutionally and permanently by the basal corticoid concentration. The catabolism and muscle loss only occur when corticosteroids levels are high. Physical exercise induces cortisol secretion increasing by the HPA axes modulation. Conclusion: Although the increased level of cortisol can produces side effects, physical training induces the development of diverse mechanisms to protect cells and tissues from the cortisol deleterious effects. So that the organism become less responsive to stress. Key words: Exercise, Cortisol, Stress

Aim: to evaluate the relationship between body fat percent (BF%) and maximal oxygen consumption (VO2 max) in police officers. Materials and methods: 32 police officers with a mean age of 40 ± 5 years performed estimates of the body fat percent (BF%) and the VO2 max by electrical Bioimpedance and by the test of 1 mile, respectively. Descriptive statistics, Pearson correlation, linear regression, chi-square and ANOVA were performed and setting a p <0.05 for differences. Results: The group had on average an elevated BF% (28.18 ± 5.73%) and excellent levels of VO2 max. (54.16 ± 7.35 ml.O2.kg-1.min-1). There was a significant (p = 0.049) moderate negative correlation (r = -0.488) between the values of BF% and VO2 max. The linear regression analysis indicates that the BF% significantly predicted the values of VO2 max (r = 0.48, R2 = 0.24, p = 0.005). It was obtained a statistical power of 85% for correlation analysis and 98% for linear regression analysis. However, no significant association was found between the classification of BF% and VO2 max. (p = 0.942). Conclusion: We concluded that, in the third battalion of officers of the Military Police of Minas Gerais, BF% correlates negatively and predicts 24% of VO2 max values. However, the high BF% in this sample population is not an impediment to obtaining good classification rates of VO2 max. Key words: Body fat percentage, Aerobic capacity, Police officers.

Activities aiming the strengthening of the abdominal muscles are widely used by practitioners of exercises, whether they are athletes, those aiming health, or aesthetics. Understanding how these exercises act at the abdominal muscles is extremely important for health professionals dealing with resistance training. There are many accessories and devices available that are believed to be more effective in activating the abdominal muscles, promising to reduce the stress on other muscles, but some doubts still remain regarding the specific effects of exercise on the development of the muscles and muscle activation. Surface electromyography (EMG) has been the most frequently used tool for studying muscle activation during exercise. We considered ten relevant studies in this review, published between 2003 and 2011. Devices such as the Ab slide, Fit ball, Torso Track, Perfect Abs, Power Wheel are very efficient in the recruitment of the abdominal muscles when compared to the crunch or sit-ups, but should be used cautiously by beginners with weak abdominal and lumbar muscles, and column pathologies. It is suggested that further studies with a greater control of variables should be realized to obtain more consistent and reliable data that can contribute to a better understanding of the subject. Key Words: Abdominal muscles; Surface electromyography; Crunch.

Our study aims to use a noninvasive indirect test reproducing the loss of linearity of heart rate associated with a direct incremental invasive test which can be considered the anaerobic threshold as the speed of running and the heart rate corresponding to the lowest glycemic value. Materials and Methods: 5 males aged 20-30 years, physically active and runners, submitted to two tests of maximum efforts to estimate the anaerobic threshold in two ways (noninvasive - analyzing the heart rate variation) and (invasive - sampling and measuring the blood glycemic). The variables were analyzed and the results were expressed as average and standard deviation, which according to a statistical there were no significant difference, comparing the three variables we observed a small difference (invasive VEL.: 11.7 km / h, VEL . noninvasive: 12km / h, invasive HR: 173bpm, FC noninvasive: 181.4 bpm, invasive Borg: Borg noninvasive 13.2: 13.6) and then, both direct and indirect tests are possible to reproduce in individuals physically active. We have a direct relationship between the tests, invasive and noninvasive when compare all variables (speed, heart rate and perception of effort) and to use the anaerobic threshold both tests are reasonable ways to prescript training. Key words: Anaerobic Threshold, Heart Rate, Blood Glycemic, Perception of Effort.

Introduction: The Low back pain affects about 80% of the population, generating an enormous socioeconomic impact totaling billion of dollars annually. The muscles have an important role in stabilizing the spine and most of these changes have improved with the introduction of physical treatment. Objective: Investigate the effects of exercise in the treatment of low back pain by means of literature review. Literature Review: Several physiological changes are found in low back pain, especially in muscles. The most common are decreased muscle activity, lack of strength, flexibility, endurance and proprioception, and atrophy of certain muscles. Among the types of exercise used, we observed a wide variety of disciplines including endurance exercises, strength, water exercises, Swiss Ball, among others. The results were the reduction of pain and disability, improve quality of life, improvement in isometric strength and endurance of paraspinal muscles. Conclusion: With the variety of type, intensity, frequency and duration found, there is still uncertainty about how best to approach. The most effective strategy seems to be individual programs, which can be considered clinically important, but limited to the practice of research, because of the difficulty of controlling variables. Key words: Low Back Pain, Exercise, Physiology, Muscle Disorders.

With the progress of the technological and scientific development happened of the industrial and technological revolution, the people meet each time more with raised level of stress, anxiety and sedentarismo what acomete the physical and mental health of the population. This picture evidences stress and without a doubt it stress it is today one of the responsible factors for alterations of the state of health and welfare of the individual. Stress it are an essential mechanism for the survival for promoting the adaptation of the human being in different situations. Constantly we alternate been of stress and homostasis, however it stress it for drawn out time or if keeping in diverse high levels cause problems to the health of the individual.Objective: To carry through a bibliographical revision in the Brazilian Archives of Endocrinology and Metabolic, Brazilian Magazine of Psychiatry and Brazilian Magazine of Medicine of the Sport on the physical activity of low intensity acting in the neutralization on stress it. Revision of Literature: He has been demonstrated in the scientific literature that the physical exercise is a stressor agent in such a way in human beings how much in animals and that exercises of high intensity reduce the cerebral serotonin for the disequilibrium between synthesis and degradation, and increase the activity of hormonal biomarcadores of stress it that they answer to the effort as cortisol, ACTH (adrenocorticotrófico hormone) and catecolaminas. In exercises carried through for people with maximum consumption of bigger oxygen that 60% of the VO2max the secretion of cortisol and ACTH is proportional the intensity of the exercise. Conclusion: The physical activity of low or moderate intensity, as well as the level of training of the individual is capable to minimize it stress and its deleterious effect.

This framework provides the appearance of pathologies and dysfunctions related to stress. This study aimed to verify the influence of stress and physical conditioning in police performance during the field of practical shooting that simulates real situations of armed conflict, with the population studied, the military police officers of the special operations group from the city of Cacoal in the state of Rondônia. The sample comprised 09 (nine) military male police officers able to the police service, with a mean age of 33.2 ± 2.34 years, and they submitted to the aerobic resistance test of Cooper, to be evaluated in terms physical conditioning and VO2max, and 88.9% of the individuals presented high levels of physical fitness with an age of 2906 ± 0.67 meter race in 12 minutes time and VO2max equivalent to 53.4 ml (kg.min) -1. The individuals were tested on a field of practical shooting to check the effects caused by stress generated before and after, through the modification of physiological variables HR and BP. The values for heart rate showed a significant difference (p = 0.5) with an increase of 113% in the number of beats a minute. There was a little significant increase (p = 0.05) BP (systolic and diastolic) at rest (mean 122.2 / 80 mmHg ± 11.2 / 9.1), before the achievement of the field of practical shooting (average 127.8 / 90 mmHg ± 10.3 / 8.2) and after (average 141.1 / 93.3 mmHg ± 14.5 / 32.1). The survey showed that the individuals were well conditioned physically, but this factor didn’t influence the control of physiological variables, interfering directly with the performance of the police officers. Key words: stress, physical conditioning, military police officers.

The office of verification of deaths (SVO) is responsible for clariflying the causes of explained deaths in the state of Espírito Santo (ES). Deaths from cardiovascular disease CVD in the most case are confirmed by autopsy. The highest incidence of cases from this service is represented by the population of the urban area where the incidence is higher in older adults between 39 and 79 years old, these citizens of lower social classes. This high incidence is possibly related to lifestyle, diet, physical inactivity, stress, lack of acess of social groups to the information on how to prevent this disease. CVD is the most common cause of morbility and mortality among these people especially in developed coutries. Analysing the rate cardiovascular disease in patients from Vitória (ES) who underwent autopsies (SVD) between January and April 2009. The reseach shows descriptive quantity field study was conduted on the data reports of necropsia and issues related to family history, lifestyle, respective the total anonymity. This study enabled us to analyze the number of deaths from (CVD) in the state of ES, occupied the first place on the causes of death, and the 300 patients who underwent autopsy were 96 deaths due to CVD main case. This death rate may be related to lifestyle that led to your daily lifestyle that in our study showed a rate of 95%. Key words: hypertension, risk factors, cardiovascular diseases.

The standard of beauty imposed nowadays is more frequent to the distortion dissatisfaction with body image, which can lead to the development of behaviors for weight control. This study has as aim to relate the body image disturbance and its associations with physical activity level and BMI in body builder practitioners in the city of Cacoal-RO. It was evaluated 117 individuals, among 18 to 35 years old, being 40 individuals of the male kind and 77 individuals of the female kind. It was applied the international physical activity questionnaire (IPAQ); the questionnaire about body image (BSQ); and it was checked the weight and the stature to the calculation for the body mass index (BMI). The results were analyzed through the BIOSTATIC program, beside the analysis of correlation of Pearson. The study pointed that there was a prevalence of normality in the perception of the body image among men and women, but the female genre presented a trend to have a light distortion of its actual and ideal body image, not being observed in the case of the male kind evaluated, what can lead, in several problems like, for example, risk of developing eating disorders. Key words: body image, physical activity level, BMI

The models proposed by Huxley of crossbridges and sliding of myofilaments normally explain the molecular and cellular mechanisms that occur during all kinds of muscular actions. However, these models cannot explain the residual force enhancement consistently observed in skeletal muscles following active stretching and its complete molecular mechanisms remains unknown. The literature points the development of sarcomere length non-uniformities and the engagement of passive elements as responsible to this residual force enhancement. The purpose of this study was to review the recent hypothesis to explain the generation and increase of force during and after eccentric contractions. We discussed about the cross- bridge theory and ATP hydrolysis during the concentric and eccentric actions. The molecular consequences of the continuity of the action potential in the formation of the cross-bridges and the action of the proteins titin, nebulin, miomesin and protein C as passive elements in the generation of force during the sarcomere stretching and in the maintenance of the myofibril integrity. Key words: muscle contraction, eccentric actions, residual enhancement, skeletal muscle, action potential, titin

In the absence of evidence to support the use of static stretching to increase the physical performance the research turned to the warm-up procedures, which aims to prepare the body for more intense physical activity. The results of this study may contribute to the understanding of the effect of various warm-up protocols on exercise performance. The aim of this study was to compare the intermittent exercise performance two warm-up protocols. Eight physically active male subjects participated of this study. The intermittent exercise involved ten all-out 6-s cycling sprints on a cycle ergometer, loaded to 7,5% of body weight, interspersed with 30 seconds of passive recovery. The warm-up protocol A involved a intermittent warmup, five minutes, with three all-out six seconds and increasing work rate. The warmup protocol B involved five minutes of continuous exercise. Shapiro-Wilk normality test was used, after Shapiro-Wilk test, T-test and the Wilcoxon test was used according to data distribution. There were significant differences in favor of warm-up protocol A in the higher power generated during the test and for the first three blocks of effort. These results suggest that performance during short bout of high-intensity intermittent exercise is influenced by warm-up type. Key words: warm-up exercise, physical exercise, performance.
