Effect of self-paced active recovery and passive recovery on blood lactate removal following a 200 m freestyle swimming trial

Purpose The aim of this study was to investigate the effect of self-paced active recovery (AR) and passive recovery (PR) on blood lactate removal following a 200 m freestyle swimming trial. Patients and methods Fourteen young swimmers (with a training frequency of 6–8 sessions per week) performed two maximal 200 m freestyle trials followed by 15 minutes of different recovery methods, on separate days. Recovery was performed with 15 minutes of passive rest or 5 minutes of passive rest and 10 minutes of self-paced AR. Performance variables (trial velocity and time), recovery variables (distance covered and AR velocity), and physiological variables (blood lactate production, blood lactate removal, and removal velocity) were assessed and compared. Results There was no difference between trial times in both conditions (PR: 125.86±7.92 s; AR: 125.71±8.21 s; p=0.752). AR velocity was 69.10±3.02% of 200 m freestyle trial velocity in AR. Blood lactate production was not different between conditions (PR: 8.82±2.47 mmol L−1; AR: 7.85±2.05 mmol L−1; p=0.069). However, blood lactate removal was higher in AR (PR: 1.76±1.70 mmol L−1; AR: 4.30±1.74 mmol L−1; p<0.001). The velocity of blood lactate removal was significantly higher in AR (PR: 0.18±0.17 mmol L−1 min−1; AR: 0.43±0.17 mmol L−1 min−1; p<0.001). Conclusion Self-paced AR shows a higher velocity of blood lactate removal than PR. These data suggest that athletes may be able to choose the best recovery intensity themselves.

Excesso de peso, nível de atividade física e hábitos alimentares em escolares da cidade de Anápolis-GO

This study aimed to identify excess of weight, level of physical activity and eating habits among students aged between 7 and 9 years. The study was of epidemiological character, cross-sectional, involving 1982 children. Results showed that overweight was lower among students of public schools. Regarding the level of physical activity, it was found that the majority of students were considered sedentary or irregularly active, and that public school students are more active. It was concluded that the students adopt levels of physical activity and eating habits far below of what guidelines suggest by the scientific literature.

Inspiratory muscle training improves strength and health-related quality of life in hemodialysis patients

Background: Patients undergone hemodialysis (HD) suffer with energy-protein malnutrition, uremic myopathy and protein catabolism reducing their functional capacity, tolerance to exercise and aspects related to quality of life. Objective: The aim of this study was to evaluate the effects of the two protocols of inspiratory muscle training (IMT) on muscle strength, pulmonary function and related-health quality of life on male HD patients. Methods: Maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP), peak expiratory flow (PEF), forced expiratory volume in first second (FEV1), forced vital capacity (FVC) and the FEV1/FVC ratio and quality of life were evaluated pre and post six months of IMT in HD patients. IMT was performed by one group using a specific training (Power breathe) device (T-IMT, n=19) and by the other with incentive spirometry (I-IMT, n= 15). Results: Following the inspiratory training, muscle strength improved in both groups. The group that used incentive spirometry had increments in MIP larger (39.8%, p<0.001) than the group that trained with the specific training device (28.3%, p=0.001). The KDQOL-SF dimensions showed significant difference in the T-IMT group in cognitive function (p=0.03), sexual function (p=0.009) and social function dimensions (p=0.04) and in the I-IMT group in the physical function dimension (p=0.03). Conclusion: It was proved that IMT improved muscle strength and I-IMT promoted increments significantly larger in MIP. Aspects of health-related quality of life of HD male patients improved significantly with T-IMT (sexual, social and cognitive functions), while I-IMT ameliorated only physical function.

Depression and anxiety in subjects with chronic non communicable diseases

Background: Modern society is undergoing socio-cultural and economic transformations. Such changes lead to situations in which the human being has to choose between his health or practicality, directly affecting his quality of life. Pathologies with a high degree of morbidity such as depression, anxiety and chronic diseases immerse themselves in this equation, and are taking alarming proportions in society nowadays. Objectives: To identify the levels of depression and anxiety in individuals with chronic non-communicable diseases. Method: This is a cross-sectional and quantitative study, consisting of 23 young adults with 20-40 years old, hypertensive or with type 2 diabetes mellitus. The symptoms of depression and anxiety were evaluated using the Beck Depression Inventory and Beck Anxiety Inventory. Results: In hypertensive patients, the mean scores for the Depression Inventory were 15.0 and for diabetics 15.6. For the Anxiety Inventory the mean scores obtained for hypertensive patients were 11.6 and 8.1 for diabetics. For the most part, both groups were classified as without depression (43.48%) and mild depression (43.48%); And without anxiety (47.9%) and mild anxiety (34.8%). Significant differences (p = 0.050) were found only in the mean scores for the Beck Anxiety Inventory between groups. No significant differences were found between the sexes. Conclusion: We conclude that the studied sample, both hypertensive and diabetic patients, mostly present with depression and mild anxiety. And when compared between the sexes the women showed to be more vulnerable than the men.

Translation, transcultural adaptation and validation of the Nordic questionnaire for the evaluation of low back pain in Brazilian adolescents

Background: Low back pain has been configured as a public health problem capable of compromising functional capacity, even in adolescents, however, there are no validated instruments for Brazilian adolescents. Objective: Validate the psychometric properties of the Nordic questionnaire for the evaluation of low back pain in Brazilian adolescents. Methods: The sample consisted of 150 adolescents (84 female), aged between 15 and 19 years. The Nordic questionnaire for the evaluation of low back pain in adolescents, was translated and culturally adapted into Portuguese (Brazil). A committee of experts followed the entire validation process. The questionnaire was administered in two moments, with a 14-day interval. Statistical analysis involved Kappa index. Results: After the slight modifications in the translation process, the expert committee considered that the Brazilian Portuguese version of the questionnaire presented semantic, idiomatic, cultural and conceptual equivalence. The results showed that, among the 15 items considered in the eight questions of the questionnaire, 66.6% presented substantial agreement (kappa between 0.61-0.80). The other items presented almost perfect agreement (kappa > 0.80). Conclusion: The Nordic questionnaire for the evaluation of low back pain in adolescents, after being translated and culturally adapted into the Portuguese (Brazil) language, showed adequate psychometric properties, with high reproducibility in all items, demonstrating that it can be used safely to evaluate the low back pain in Brazilian adolescents.

Body temperature and dehydration rate in adolescents undergoing the Cooper s 12-minute run test

Background: During the practice of any physical exercises is produced heat. About 30% of this heat is transformed into work and the other 70%, distributed to the body, thus increasing the body temperature of the individual. Objective: to identify changes in body temperature and hydration of adolescents classified as physically actives or inactives. Methods: This is a cross-sectional, quantitative, descriptive study with 40 students (13-17 years old) from a private school in Anápolis-GO. The tympanic and forehead body temperature and body mass were measured. The urine produced was then collected and the hydration state was estimated before and after the 12-minute run test, which was used to calculate the VO2max. After checking the normality of the data, the paired “t” test was performed to compare the pre and post-run data and a “t” test for independent samples to compare the groups denominated: active and inactive. Results: there was no significant difference in relation to the temperature pre-and post-test of the Cooper protocol in active and inactive individuals, but the active group had a higher central temperature. The active group presented a greater reduction of body mass and a worse state of dehydration, evaluated by the urine color, and also by the calculation of the rate of sweating. Finally, although both groups received the classification of “weak” regarding aerobic capacity, the active group was significantly superior to the inactive group. Conclusion: the group of actives adolescents presented higher central body temperature, with a higher rate of sweating, due to their greater physical effort (better test performance) and their better training, which can lead to a better body cooling system.
