title: Somatotypes, risk factors and waist-height ratio in physically active individuals

description: INTRODUCTION: The relationship between physical type and cardiovascular risk has been studied in several populations worldwide. In Brazil, studies evaluating this relationship are scarce, especially when physically active individuals are concerned. Objective: To analyze the relationship of the somatotype with cardiovascular risk factors and waist-height ratio (WHtR) in physically active individuals. METHODS: This is a descriptive cross-sectional study. The sample consisted of 280 individuals, users of the jogging track at the Federal University of Pernambuco (UFPE) in Recife, PE, Brazil. To identify the level of physical activity, we used the short version of the International Physical Activity Questionnaire (IPAQ). Individuals classified as very active, active or irregularly active A or B were included in the sample. Physically inactive individuals were excluded from the analysis. The somatotype was estimated by the anthropometric protocol proposed by Carter and Heath (1990). We determined as cardiovascular risk factors smoking, alcohol consumption, and blood pressure (BP). We used descriptive statistics to characterize the sample, and then used a multivariate analysis of variance (MANOVA) with a significance level of p&lt;0.05. RESULTS: No significant relationship for the variables smoking and alcohol consumption. In the analysis of BP (Pillai's trace = 0.082; F=8.187; p&lt;0.05) and WHtR (Pillai's trace = 0.298; F=39.081; p&lt;0.05) there was statistical significance for the somatotype. CONCLUSIONS: The physical type was positive and significantly related to BP and WHtR, showing that this anthropometric indicator can be used for early prediction of the risk of developing cardiovascular diseases.

title: Comparison between the direct and indirect methods of VO2máxdetermination in runners

description: INTRODUCTION: direct tests are considered "gold standard" for determining physiological variables. However, the financial cost is high and there is the need of skilled labor for its operation. Thus, the indirect tests are used by most professional of Physical Education as an affordable alternative to the lack of direct measurement.OBJECTIVE: to compare the values of maximum consumption of oxygen (VO2max), determined directly by a system with spirometry values determined from indirect protocols.METHODS: 15 male individuals participated (27.4 ± 3.5 years), physically active, who performed the incremental test on treadmill for the direct determination of VO2max with the gas analyzer. The tests for the prediction of VO2max were ErgoPC; Polar Fitness Test, test bank and Cooper. We used descriptive statistics (mean ± standard deviation - SD); the sphericity was tested by Mauchly's test, the methods were compared by ANOVA of repeated measurements, with Bonferroni adjustment for multiple comparisons. Data normality was evaluated by the Shapiro-Wilk test, and the Pearson correlation coefficient was also applied, adopting a significance level of p &lt;0.05.RESULTS: the average VO2max was determined directly from 55.8 ± 6.1 ml • kg -1 • min-1 and the values for the indirect tests, the percentage of underestimation and correlation coefficient were, respectively: 33.7 ErgoPc ± 4.5 ml • kg -1 • min-1(39.6%, r = 0.71, p &lt;0.001); Polar Fitness Test 53.2 ± 6.4 ml • kg -1 • min-1(4.6%, r = 0.64, p = 0.774); bank test 48.8 ± 6.3 ml • kg -1 • min-1 (12.5%, r = 0.60, p = 0.001 ) and Cooper 43.9 ± 7.9 ml • kg -1• min-1 (21.4%, r = 0.65, p &lt;0.001).CONCLUSION: the indirect methods may suggest overload in lower or higher training for required physiological adaptations and only the Polar Fitness Test showed no difference statistically significant.

title: Effect of aerobic training on plasma levels of homocysteine in patients with type 2 diabetes

description: INTRODUCTION: Aerobic training programs have shown good control of cardiovascular risk variables in diabetic subjects, but the effects on homocysteine levels remains unclear. Objective: To analyze the effects of aerobic training on plasma homocysteine levels and cardiovascular risk factors in patients with type 2 diabetes. METHODS: The study included 15 women with type 2 diabetes, mean age 68.86 ± 11.2 years. All individuals in the sample underwent an evaluation test of maximal oxygen uptake (VO2max) according to Bruce protocol, evaluation of blood pressure and anthropometric measurements. Additionally, a sample of venous blood (10ml from cubital vein) was drawn from subjects fasted for at least 12 hours. The plasma was separated and processed for further analysis of homocysteine concentration (mmol/l), total cholesterol (mg/dl), very low density lipoprotein (VLDL) (mg/dl), low density lipoprotein (LDL) (mg/dl), high density lipoprotein (HDL) (mg/dl), triglycerides (mg/dl) and blood glucose (mg/dl). The tests were done before the aerobic training and repeated 16 weeks later. The program consisted of 2 non-consecutive training sessions of 75 minutes a week, between 60% and 70% of maximum heart rate. RESULTS: The observed results show that physical exercise program induced a non-significant decrease in plasma concentration of homocysteine. Were also identified improvements in lipid profile and maximal oxygen uptake (VO2max), decreased blood glucose, diastolic blood pressure, body fat percentage and body fat. CONCLUSION: The aerobic training program reduced cardiovascular risk factor in individuals with type 2 diabetes, although homocysteine decline was not significant.

title: Metabolic transition in trained people in progressive test with resistance training and running

description: INTRODUCTION: The specificity of cardiorespiratory and metabolic adaptations of aerobic and strength training evoke different responses during cardiopulmonary exercise testing (CPET). Objective: To describe the cardiorespiratory behavior during metabolic transition (MT) of CPET, runners and bodybuilders compared to a control group. METHODS: Men aged 21-55 years were grouped as follows: runners group (RG, n=30), strength group (SG, n=23) and control group (CG, n=38). The subjects underwent anthropometric and CPET assessment with analysis of ventilatory anaerobic threshold (VAT) and the respiratory compensation point (RCP). We calculated the running economy by the relationship between VO2 and test speed (ECINCLINA). RESULTS: In metabolic transition phase, the running speed (km/h) was higher in the RG group (4.2±1.6) vs. CG (2.7±1.6) and SG (2.8±1.0); P&lt;0.05. The RG had higher VO2LAV, VO2PCR, and VO2MAX (36±8; 46±8, 51±8 vs. 24±6, 35±5, 40 ± 6, and 26±6, 35±6, 40± 7ml.kg-1.min-1; P&lt;0.05) compared to group CG and SG, respectively, even after allometric correction. The resting heart rate was lower among RG and CG (R=52±6; C=60±8 bpm, P&lt;0.05). In the MT phase the RG had a greater increase in workload and less change in oxygen pulse compared to CG and SG. The VO2 during MT did not differ between groups. The RG showed lower ECINCLINA in the closing stages of the test compared to CG and SG. CONCLUSION: The RG showed higher metabolic efficiency in progressive transitions of effort intensity in relation to CG and SG and the SG does not display enhanced transition capacity in CPET, even when compared to sedentary individuals.

title: FACTORS ASSOCIATED WITH CARDIORESPIRATORY FITNESS IN SCHOOL STUDENTS

description: ABSTRACT Introduction: There is a high prevalence of youth that not meet the health criterion for cardiorespiratory fitness, which exposes them to risks related to metabolic, cardiovascular and mental health. Thus, it is relevant to investigate which aspects are associated with cardiorespiratory fitness in youth. Objective: To analyze the factors associated with cardiorespiratory fitness in school students. Methods: Cross-sectional study involving 736 students (50.1% female) with age between 10 and 18 years. The following has been analyzed: the socioeconomic condition, paternal education, number of siblings, physical activity perception, moderate to vigorous physical activity, participation in physical education classes, sport practice, place to practice, active transport and sedentary behavior. Height and body mass were measured and a cardiorespiratory fitness test was performed. Prevalence ratio (PR) and 95% confidence intervals were estimated using the Poisson regression. Results: For students aged less than 14 years, variables that presented association with cardiorespiratory fitness were female sex (PR = 0.79, 0.68-0.91), overweight (PR = 0.73, 0.61-0.89), physical activity perception equal to persons of the same age (PR = 1.26, 1.03-1.53), weekly physical activity 3-6h (PR = 1.21, 1.05-1.38), participation in physical education classes (PR = 1.35, 1.03-1.76), and sedentary behavior ≥ 2h (RP = 0.82, 0.73-0.94). With respect to students aged 14 years or more, female sex (PR = 0.35, 0.19-0.63), overweight (PR = 0.25, 0.09-0.66), practicing sports a few times (PR = 1.96, 1.00-3.81) and frequently (PR =2.09, 1.01-4.31) presented association with cardiorespiratory fitness. Conclusion: Intervention programs aiming at increasing health criterion requirement for cardiorespiratory fitness of students should promote moderate to vigorous physical activity, sport practice, participation in physical education classes and overweight reduction.

title: RELATIONSHIP BETWEEN TRAINING VOLUME AND BONE MINERAL DENSITY CHANGES IN ELDERLY WOMEN

description: ABSTRACT Introduction: Several studies have analyzed the relationship between physical activity and bone density. However, the prescription of exercise is not entirely clear as to the type, quantity and intensity. Objective: The objective of this study was to determine if there is a relationship between the amount of exercise and changes in bone mineral density. Methods: Fifty-two women, members of the Municipal Program of Physical Activity for Seniors, voluntarily underwent two ultrasonographies of the calcaneus within a 6-month interval. During this period, all physical activity was recorded. Afterwards, a lineal correlation study was carried out between the amount of exercise and bone changes, expressed as T-Score variation, first in total number of participants and then in groups. Considering the average body weight obtained for all women, two groups were created ("light" &lt; 69 kg and "heavy" &gt; 69 kg). Later, women who had participated in less than 72% of the targeted program were excluded from both groups, and the differences between the groups "light and trained" and "heavy and trained" were analyzed. To do so, the nonparametric Mann-Whitney U test was used. Results: A significant relationship of r= -0.59 was found between the total amount of exercise and the T-Score variation in the group of women above 69 kg. Significant differences were found between the "light and trained" group and the "heavy and trained" group with respect to the variation of T-Score. Conclusion: The effect of exercise on bone mineral density is determined, somehow, by body weight. This interaction is due, possibly, to mechanical demands difference.

title: THE INFLUENCE OF THERMOTHERAPY IN THE FLEXIBILITY GAIN OF THE HAMSTRING MUSCLES

description: ABSTRACT Introduction: Muscle flexibility is described as the ability of the muscle to extend its fibers, influencing joint mobility. Diathermy applied to the muscles prepares the body for physical activity, by accelerating the metabolism of the muscle fibers and decreasing the intramuscular resistance, thereby increasing the range of motion and the mechanical efficiency. Cryotherapy has various physiological functions when applied to the human body, which, together, provide muscle relaxation. Objective: To evaluate the flexibility of hamstring muscles by applying passive stretching associated with hot and cold thermotherapy. Methods: This study consisted of 24 volunteers of both sexes randomly divided into three groups: passive stretching group (G1), cryotherapy preceding passive stretching group (G2) and diathermy preceding passive stretching group (G3). The volunteers were evaluated for range of motion by goniometry of hip flexion with the knee extended, with an initial assessment carried out before starting the protocol and revaluations at the end of each of the four weeks of intervention. Results: There was significant increase in hip flexion in G2 and G3 compared to G1. There was no statistical difference between G2 and G3. Conclusion: The use of diathermy and cryotherapy associated with passive stretching is favorable for increasing muscular flexibility and hence the amplitude of motion in healthy young adults.
