Despite the advancement of research in relation to the value of resistance exercise in the overall treatment of type 2 diabetes , little is known about the profiles of acute glycemic response in these individuals, the different resistance training protocols. Given the dearth of study of this proposition, our study aims to determine the acute glycemic impact of a session of resistance exercise circuit consisting of twelve exercises, conducted alternately by muscle group, performed in a single lap on the circuit with 20 submaximal repetitions in diabetic non-insulin dependent. We recruited 10 sedentary volunteers of both sexes, with at least 2 years of diagnosis of the disease, which only made use of oral hypoglycemic agents for glycemic control. The results showed significant difference (p <0.05) between the pre-exercise 203 mg/dl and post-exercise 161 mg/dl, a reduction of 20.7%, allowing us to conclude that resistance exercise sessions performed under the method of circuit, with moderate intensity and submaximal repetitions, further significant reductions of blood glucose monitoring and can be prescribed without metabolic risk for diabetic non-insulin dependent. Key words: Resistance exercise, Circuit, Blood Glucose, Diabetes Mellitus.

This study reviewed the physiological mechanisms and ways to implement maximum dynamics strength training for potentiate subsequent muscle actions carried out quickly, such as jumping or running on maximum speed. After the application of resistance exercise involving the maximum strength, molecular changes and alterations in motor recruitment by nervous system makes the exercise of quick strength become more efficient, a phenomenon known as post-activation potentiation. When performing this training method, the quick and maximum strength can be trained in one training session (microcycle), with both being optimized. After reviewing the more relevant publications on the subject, this paper proposes how to adopt this methodology in practice. The application of this method is important for athletes who use the quick strength on its modalities, such as soccer, basketball, volleyball and others or for those who wish to include this training within a certain stage in the assembly of your training program (periodization). Key words: Periodization; Microcycle; Maximum strength; Quick strength; Training methods.

To compare the acute responses of heart rate (HR) and blood lactate concentration between the methods superset and growing pyramid. Twelve male subjects (25.17 ± 3.64 years, 80.33 ± 8.24 kg, 175.58 ±3.75 cm and body fat percentage 15.34 ± 3.77%) underwent two sessions fitness by performing superset of the methods of superset and growing pyramid, with a week between the completion of training. During the execution of the methods of HR were monitored for blood collection and verification of lactate concentrations in the pre, 0'pós, 5'pós and 15 'post workout. In intragroup comparison was carried out repeated measures ANOVA with post hoc Bonferroni. In intergroup comparison was performed the Student t test for paired samples comparing the values of delta (Δ). The significance level was p <0.05. The results showed significant increase in blood lactate concentrations and heart rate at all times after the training session compared to the pre (p <0.001). In the comparison intergroup (Δ value), changes in HR (Superset = 73.6 bpm vs. Growing Pyramid = 34.8 bpm, p <0.001) and lactate production (Superset = 5.7 mmol/L vs. Growing Pyramid = 3.5 mmol/L, p=0.034) were significantly higher in the method superset. We conclude that although both methods of training in bodybuilding cause a major metabolic stress, the method superset provided the greatest acute chances.

The aim of this study was to compare the responses of heart rate (HR), systolic blood pressure (SBP) and double rate product (DP) in different body positions in resistance training (RT) to the lower limbs. The study included eight volunteers (five men), normotensive and with previous experience in RT, 23±1 (years), 63.8±10.6 (kg), 169.7±9.5 (cm). The exercises chosen were the squat bar guided (SQ) and leg press 45º (LP). The volunteers performed four visits to the study site with a minimum interval of 48 hours. Initially, we used the test-retest of 10 repetitions maximum (10RM) in both exercises. In the following days, the participants performed at random, three sets of 10RM maximum load with an interval of two minutes between sets. The HR and BP were measured at rest and immediately after each series by a frequencimeter (FS2, Polar Electro OY®, Finland) and an aneroid sphygmomanometer and stethoscope adult model (Kole ®, Brazil), respectively. We conducted a normality test and then used the two-way ANOVA with repeated measures followed by Tukey Post-Hoc test to compare the responses between the variables. The HR in MA was significantly higher in the 1st and 3rd grade, while the SBP was higher in the LP, only in 1st grade. The DP was higher in MA only in 3rd grade. It follows that the MA caused greater acute cardiovascular responses in comparison to the LP. Key words: Blood Pressure, Heart Rate, Muscular strength, Resistance training.

The present study aimed to evaluate the functional autonomy in a group of elderly people who practice hydro gymnastics. The sample consisted of eight female volunteers (74.5 ± 8.5 years; 164 ± 6 cm; 65.5 ± 5.5 kg) who do water exercises three times a week for at least two years. For the evaluation of functional autonomy, subjects performed a battery consists of six tests proposed by the protocol for functional assessment of the Group of Latin American Development to Maturity (GDLAM), consisting of: walking 10 meters, rising from a seated position, lift the prone position, rising from a chair, moving around the house, and clothe and take a shirt. The test results were used to calculate the index GDLAM (IG). Of the eight participants, five had GI rating of "GOOD" and three participants were classified as "REGULAR", which is considered the minimum standard for the evaluation of functional autonomy proposed by the protocol. The results show that the regular practice of gymnastics can be efficient in maintaining the functional autonomy of elderly at satisfactory levels with similar characteristics of the sample.

The objective of this study was to evaluate the effect of the thermal stress on the hydration over a volleyball class. Participants were 18 students of Physical Education (9 males and 9 females), with age of 22,61±1,46 years, height 164,7±7,65cm, body weight 64,41±12,02kg. The fluid intake was "ad libitum" and the urine was collected before and after the class. The height and weight and, the evaluation of the dehydration through the density of the urine (Du) were measured by a digital stadiometer (WISO, W721), and refractometer, (Instrutherm, RTP-20ATC), respectively. The environmental conditions were registered by a digital thermo-hygrometer (Instrutherm, HT-260). The temperature and the relative humidity of the air were, respectively, 35,46±1,21 °C and 45,86±2,79%. The statistical analysis were based on t student test (p≤ 0,01). The water ingestion was 473,14±279,30 ml/h and the corporal weight at the end of the class was 63,77±12,07 Kg, the Du before and Du after were, respectively, 1022,56±8,02 and 1027,44±7,41SG. There was significant difference for Du. The amount of water ingested probably was not enough to hydro homeostasis. It is possible that the mechanism of the thirst was not efficient to maintain the water normality and that the allied exercise to the stress thermal increased the dehydration. Key words: Dehydration, density of the urine, environmental conditions.

The exhaustive exercise promotes increased formation of reactive oxygen species (ROS), inducing lipids and proteins oxidations of cell membranes. The objective of this study was to investigate the correlationship between the lipid peroxidation (TBARS) and Creatine Kinase (CK) plasma levels in mices submitted to swimming training and overreaching sessions. We used sixty mices like "Balb-C", obtained from the Center of Biotery-UNICAMP. The animals were divided into 3 groups (n = 20): control (CO), training (G-T) and overreaching (G-Over). The G-T performed progressive training, beginning with sessions of 10-minutes and finishing this step with 60-minute sessions, which lasted three weeks. The G-Over, after conducting the training sessions mentioned, had an increase in the number of daily training sessions (up to 4 times per day). The G-Over training lasted two weeks. The results showed significant increases in CK levels for the G-T (36,8 ± 5,35 U/L; *p<0.01) and G-Over (98,4 ± 4,39 U/L; **p<0.001) compared to CO (18,7 ± 0,75 U/L); the same as for TBARS: G-T (5,5 ± 0,6 nmol/mL; *p<0.01) and G-Over (10,76 ± 0,75 nmol/mL; **p<0.001) compared to CO (2,66 ± 0,81 U/L). In conclusion, we observed a high degree of correlationship between the CK and TBARS plasma levels (c=0.978), suggesting that the use of measures of CK, a parameter more accessible and simple, can be an important tool for modulation of training loads. Key words: swimming, oxidative stress, creatine kinase, lipid peroxidation, overtraining.

Creatine is a nitrogenous compound found mostly in foods of animal origin, being used as an ergogenic supplement aimed at improving performance in physical exercise, especially high intensity and short duration. In foods, creatine is found in greater amounts in meats, cod - 3.0; sole - 2.0; salmon - 4.5; tuna - 4.0, and beef - 4.5 g / kg. It is also found in other foods, but in small quantities. Daily, an adult with a regular diet varied, eat roughly 1.g creatine, and a similar amount is produced by the liver to meet the daily needs. This present study employed a systematic review of creatine supplementation and its effects on human physical performance, this study also report the energy supply and metabolism of creatine and its causes in the composition of the human body. The studies used in this study were those who attended the models double-blind study (supplemented group and placebo group) and questionnaires that addressed the use of dietary supplements, with emphasis on studies published over the past 13 years, preferably studies of Brazilian origin. Previous research has suggested that creatine supplementation can increase muscle concentrations of this compound either in free or phosphorylated, improving performance in activities of high intensity and short duration. This review concluded that that creatine supplementation leads to increased levels of muscle phosphocreatine, thus, can promote increases in strength and hypertrophy and improvement in physical performance.

The objective of this study was compare the number of repetitions achieved 80% of 1RM between single and multiple joint exercises for the chest and compare the number of repetitions achieved with the number predicted by the literature for the intensity of 80% of 1RM. We selected 10 men years (22.3±2.6, Kg 74.9±11.1, cm 176.9±4.9) engaged in resistance training, which carried a maximum grade of 80% of 1RM until concentric fatigue. The exercises were pack deck fly and the bench press. The number of repetitions achieved in pack deck fly (10.4±2.0) was higher than in the bench press (8.3±2.3), but no significant difference was found. By comparing the repetitions of the exercises by the number of repeats expected in the literature, the pack deck fly showed a significantly greater number of repetitions. Therefore, the determination of exercise intensity by percentage of 1RM should not be used to prescribe strength training. Key words: Maximal strength; Resistance training; Strength training.

Pilates Method has been detached as a sort of physical activity which proposes an enhancement in quality of life through specific exercises on a mat on the floor and/or in exercise equipment specifically developed which promote gains in flexibility, elasticity and muscle tone, which in turn provide better agility, mobility and balance. Some studies have shown the relationship between the method and improvement in flexibility due to its importance in quality of life and prevention of musculoskeletal disorders caused by sedentarism or even by natural body aging. The aim of the present study was to demonstrate the benefits of the Pilates Method in terms of flexibility enhancement. Thirty articles were reviewed, from 2003 to 2010, from which 07 were selected for analysis. The main database researched were PubMed, Scielo and scholar.google. The studies were developed with different groups of participants, probably, because the beneficial effects in flexibility that the Method has been demonstrating. The studies were preformed with young athletes, who incorporated the method to high performance training programs, with low back pain and other pathologies in a wide range of age groups and with healthy seniors. From de 07 studies selected, 06 have shown effects of the continuous training program with the Pilates Method exercises in terms of flexibility improvement and 01 have made some relationship of the flexibility improvement with increased low back pain. The results confirm the efficacy of the Method in flexibility, muscle strength and quality of life improvements for all participants and none of them has demonstrated negative aspects, taking into account for the importance of the continuous training program.

Due to the low level of physical activity and high consumption of processed foods and calories, the number of obese children is increasing. We emphasize that obesity is the increase of adipose tissue in the body and is strongly tied to hormones. In school is where the student beginning to have major stimulus for better nutrition practices, physical activities and orientation for parents. The aim of this study was to compare the level of incidence of overweight among students in public and private schools in different cities. 49 public school students and 28 private school students participated of this study. Were evaluated the skin folds, height, weight and body mass index through the 50th percentile. The study was conducted in association with use of chi-square considering the significance level of 5%. All data were processed in SPSS 13.0. There was no significant difference between students in the classifications: eutrophic (private = 53.6%, public = 51%), risk for overweight (private = 10.7%, public = 10.2%), overweight (private = 10.7 %, public = 8.2%) and underweight (private = 25%, public = 30.6%). For changes happen everyone must participate, parents, teachers and school one depending another with stimulus of healthy eating and physical activity practices guided by a physical education teacher. Can conclude that in this study, social status was not determinant to cause differences in the body classification between the students of public and private schools.

The cardiovascular system is among the organic systems, one of the most changes during the practice exercise. An indicator to indirectly determine the rate of myocardial infarction is the rate pressure product (RPP), which is the product of heart rate (HR) and systolic blood pressure (SBP). The purpose of this study was to analyze these variables in three different intensities of resistance exercise training. The study consisted of six volunteers who underwent a protocol of three series specific repetition maximum (RM), divided into 6RM, 12RM and 25RM, with one minute between sets on the leg press 45º aparrathus. The results showed significant difference in SBP between the first and the other series in 12RM. They also found differences between 6RM and 25RM in second set. In the same RM, the HR was different between the first and third series in 25RM. When comparing the RM, we obtained a difference in the first and second series between 12RM and 25RM. Moreover, in third grade the intensity of 25RM was higher when compared to others RM. The RPP was different between the first and the other series in 12RM. There was a difference between 12RM and 25RM in the first series, the intensity of 25RM was different in the second and third series when compared to the other. According to the results, we concluded that the intensity of 25RM had a higher cardiac overload, when compared to other intensities studied. Key words: Blood pressure, Heart rate, Rate pressure product, Resistance exercise.

This study had as goal to compare the number of Repetitions Maximum (RM) accomplished through different percentages of lRM between the horizontal supine exercise done with Free , Weight (FW) and those executed using Weight Resistance Training (WRT) Machinery (MAC) when experienced individuals not much proficient individuals are submitted to the effort. Have participated voluntarily in the study 20 men (10 experienced individuals and 10 not much proficient individuals to the WRT). First1y the individuals executed tests of lRM and after RM tests with two seconds controlled velocity to the eccentric phase and the same time to the movement's concentric phase, in different days, with intensity of 90%, 75% and 60% of IRM in MAC and FW. The ANOVA three factorial (2x3x2 - measurement instrument, % of lRM and familiarization leyel) for repeated measures in the 1° and 2° factor only showed significant differences between the RM avetages forefront the different weight intensities (% of lRM). It is concluded that the RM number does not differ amid MAC still FW at an identcal % of 1 RM such phenomenon also does not show dependence to the individual's familiarization leveI to WRT nevertheless. Key words: Weight resistance training, Strength, Training methodology.

Hypothyroidism is a pathology characterized by a decrease of the hormones thyroxine (T4) and triiodothyronine (T3), which causes several structural disorders in the body. One of these disorders is the decrease in bone mass caused by calcium loss in the diminution of the metabolism of bone cells. It can found in the literature showing that aerobic exercise increases bone mass gain rehabilitating it in a healthier state. This study aimed to analyze the effects of 120 days of swimming training on bone behavior of rats in condition of hypothyroidism. We used 24 rats Rattus Norvegicus, male with approximately 45 days, weighing 200g / 250g randomly divided into four groups: Trained group in a state of hypothyroidism (GT-HIPO), Sedentary group on condition of hypothyroidism (GS-HIPO), Trained group – distilled water (GT-AD) and sedentary group – distilled water (AD-GS). The GT-HIPO and GT-AD were trained for five days/week for 1 hour with overload attached to the thorax corresponding 5% of body weight of each animal. After 120 days the animals were sacrificed to remove the femur, radio, tibia and humerus to analyze their length and weight. Among the findings, the length of the bones did not achieve significant difference, but the weight was significant (p<0,05) in the humerus and the femur in GT-AD and GS-AD when compared to the GT-HIPO and GS-HIPO, in tibia and the radio GT-AD and GS-AD compared to in the GT-HIPO. Therefore, this study failed to achieve the desired hypothesis, which would be a change both in bone length and weight. Key words: Cretinism. Physical exercise. Bone mineral density.

Objective: The objective of this study is to verify if it exists differences in the circumferences of upper and lower members from the right and left sides of Beach Volleyball athletes from the State of Santa Catarina, of both sexes between the ages of 18 and 45 years old. Materials and Methods: 14 athletes took part in this study, 7 female and 7 male, and it was carried out in a gym in Itapema with the authorization of the director. Results: For the variables (weight, height and BMI) two groups (female vs. male) with heterogeneous values were observed (w = 0,00). The male BMI showed these values: 43% eutrophic, 29% overweight and 29% with obesity degrees, meanwhile the women were 100% eutrophic. Conclusion: To sum up, the men showed bigger arm perimeters compared to the women. When compared the dominant and non-dominant sides of the same sex, the study presented symmetries in the muscle circumferences of beach volleyball athletes. Key words: muscle symmetry, unilateral.
