title: Correlation between functionality, mobility and risk of falls in elderly people with Alzheimer’s disease

description: Abstract To evaluate functional capacity, mobility and balance in elderly patients with Alzheimer's Disease (AD), in its mild, moderate and severe forms, verifying the existence of correlation among these parameters. Eighty-eight elderly patients (81.79 ± 6.54 years) diagnosed with AD treated at an elderly care reference center in Taguatinga-DF were selected, and information was collected between November 2018 and March 2019. Data collection was initially made by filling in the evaluation form. Subsequently, two questionnaires were administered to caregivers (Clinical Dementia Rating-CDR and Disability Assessment for Dementia -DAD) and two tests to demented patients (Southampton Assessment of Mobility-SAM-Br and Timed Up and Go-TUG). Variables were correlated using the SPSS software version 22 using Pearson's correlation, with significance level p?0.05. The following results were obtained: 1. weak correlations between CDR and DAD (p = 0.04; r = -0.31) with significant difference; 2. strong correlation and significant difference between CDR and TUG (p = 0.02; r = 0.87); 3. weak and non-significant correlation between CDR and SAM-Br (p = 0.14; r = -0.24); 4. significant difference and highly strong correlation between SAM-Br and TUG (p = 0.01; r = 0.70). Older adults with Alzheimer's disease present decreased functional capacity, mobility and risk of falls associated with the disease progression. SAM-Br and TUG tools showed strong correlation and, although it is a generic measure, TUG showed strong correlation with AD progression, and may be a predictive test for the risk of falls in this population.

title: Body image perception and satisfaction in university students

description: Abstract Body image represents the mental perception of body shapes and is a multifactorial structure that includes psychological, physical and emotional elements. The discrepancy between the subjective perception of body image and the desire for the ideal body type can interfere with the feeling of satisfaction and trigger the desire for changes in appearance, directly interfering with mental health and general well-being. Men and women may differ in body image satisfaction due to the different social influences and beauty standards imposed. The aim of this study was to evaluate the subjective perception of body image and satisfaction with body shapes among men and women. The sample consisted of 100 college students of both genders. Subjective perception of body image and satisfaction were measured through self-assessment, through scale figure silhouettes. There was a significant difference in the subjective perception of body image in the comparison between genders, and women presented greater discrepancy between the real and the perceived image. In the analysis of satisfaction with body image there were no differences between genders and both presented high percentage of dissatisfaction. In addition, 46.2% of men would like to decrease their body shapes, 53.8% would increase them. As for women, 76.1% would like to decrease their body dimensions and 23.9% to increase them. The strong pressures imposed by society and the standards set by the prevailing media in determining body image dissatisfaction or self-assessment negatively, regardless of gender.

title: Food consumption, physical activity level and sedentary behavior in schoolchildren

description: Abstract Dietary intake inquiry, physical activity (PA) and sedentary behavior (SB) surveys are practical tools for identifying habits among the pediatric population; however, the results of describing these behaviors appear to be restricted to large centers. The objective was to analyze dietary intake, PA and SB level in schoolchildren. Children from 6 to 10 years old, coming from public and private schools were evaluated for anthropometry, dietary pattern, PA and SB level. A total of 1408 children (48.1% male) with a mean age of 8.05 (± 1.53) years participated in the study. Only 4.6%, 4.9% and 17.2% of children met the recommendations for fruit, milk and dairy products, respectively. 40.4% and 59.5% of the children did not meet the recommendation for soft drinks and meat consumption, respectively. More than 75% of children met the recommendation for the consumption of packaged snacks, candies and beans. There was a difference between genders only for candy consumption (p=0.003), with a higher proportion of boys meeting the recommendations. Approximately half and one third of the children complied with the recommendations for moderate to vigorous PA and SB, respectively. Risk behaviors for cardiovascular disease were observed in children, characterized by low consumption of fruits and vegetables, low levels of PA and excessive time in SB.

title: The effect of 10 weeks of strength training on the electromyographic response of quadriceps portions

description: Abstract This study investigate the effect of 10-week strenght training on the amplitude of the electromyographic (EMG) signal of vastus medialis, vastus lateralis and rectus Femoris. Twenty three untrained volunteers performed 3-5 sets (3 sets - weeks 1 and 2; 4 series - weeks 3 and 4; 5 series weeks 5 to 10) with 6 repetitions, intensity of 50% of 1 repetition maximum (1RM), 3 min rest between sets and 6 s repetition duration at the knee extensor exercise. One group (5:1) performed concentric action of 5 s and eccentric of 1 s and the other (3:3) performed concentric of 3 s and eccentric of 3 s. The VM, VL and RF EMG (RMS) activities were recorded in each repetition of the three series at the first training session and the first three series at the last session. The protocol 5:1 led to EMG reduction in all portions, with a greater number of repetitions presenting differences at the VL and RF. VM and RF presented similar results at Group 3:3. It was verified that all the differences occurred in the second half of the series. It was also verified differences in EMG ratios just in group 3:3 and only in VM/VL and VM/RF. These results suggest that the coordination was not affected when equivalent repetitions of series were compared. It was also suggested that these results were influenced by the reduced degrees of freedom of the exercise and the training load progression adopted.

title: Analysis of aerobic testing in basketball referees and heart rate recovery time

description: Abstract The study analyzed the physical conditioning and the time of recovery of the maximum heart rate of 12 international referees being used the test of 20 meters with beep to evaluate the cardiorespiratory conditioning, with the frequency to control the recovery time of the maximum cardiac post test. The majority of the referees obtained a recovery of heart rate greater than 50% in 3 minutes, were those that reached the levels of good to excellent in the table of maximum Vo2. Even with some factors influencing their physical performance most of the referees were able to complete the aerobic test and obtained a good recovery of the heart rate, the others that failed to reach the test goal had the HR recovery in 3 minutes much lower than expected, thus highlighting the association of the maximum VO2 level between good and excellent with the recovery of the heart frequency.

title: Graded and ramp protocols present similar results in apparently healthy subjects

description: Abstract The aim of the study was to compare maximum oxygen uptake, maximum heart rate, speed corresponding to VO2max, time to exhaustion, and ventilatory thresholds between two maximal test protocols (scaled vs ramp) with equalized metabolic demand in apparently healthy young adults. Twenty-seven subjects of both sexes were analyzed and submitted to two maximum tests: 1) scaled test with 1.2 km∙h-1 every 2 min; 2) ramp test with 0.1 km∙h-1 every 0.18 min; both with 1% slope and maximum total duration of twenty minutes. Respiratory gas exchanges were directly analyzed, and ventilatory thresholds determined through visual inspection. Central tendency and dispersion measures were adopted, as well as paired t-test and effect size. Bland-Altman analysis verified the agreement among variables. Maximum speed showed significance difference (p &lt; 0.01) for the scaled test (14.0 ± 1.9 km∙h-1) and ramp test (14.6 ± 2.3 km∙h-1). Even with small BIAS values, negative trend and high limits of agreement could be observed. Despite the non-difference presented for variables, except for maximum speed, it could be concluded that the scaled test is able to determine the analyzed variables similar to the ramp test, considering the same conditions of the present study.

title: Muscle thickness and functional performance of patients with Parkinson’s disease

description: Abstract The aims of this study were: a) to check if there is difference between muscle thickness measured by ultrasonography at three different sites, elbow flexors and knee extensors of patients with Parkinson's disease (PD); b) to check if there is correlation between muscle thickness and functional performance in patients with PD. Muscle thickness was assessed by ultrasonography at three anatomical sites in elbow flexors (proximal - EF1, medial, EF2, and distal - EF3) and knee extensors (proximal - EK1, medial - EK2, and distal - EK3), as well as functional performance assessment (chair stand and arm curl) of 31 patients with PD. The results suggest that EF3 muscle thickness was significantly (p&gt; 0.05) lower than EF2 and EF1. Muscle thickness of knee extensors was statistically different in the anatomical points of rectus muscles and vastus medialis muscles (EK1&gt;EK2&gt;EK3). There was no correlation between muscle thickness and functional performance of lower (r= 0.17; p= 0.35) and upper limbs (r= -0.17; p= 0.34) of PD patients. The results indicate that the anatomical point has significant influence on the muscle thickness of elbow flexors and knee extensors of patients with PD. Thus, the careful determination of the evaluation of muscle thickness sites is a key variable when the goal is to quantify muscle thickness in patients with PD.

title: Effect of volume of practice in children with probable Developmental Coordination Disorder

description: Abstract Children with Developmental Coordination Disorder (DCD) demonstrate a slower and more gradual ability to acquire and learn motor skills with practice. One question then is whether a higher volume of practice for these children could match the performance of children with typical development (TD). The present study aims to examine the effects of a higher volume of practice by children with probable DCD (pDCD) in relation to a lower volume of practice by children with TD. The MABC-2 was used to identify the participants' level of motor difficulty and set the composition of the groups. Two active video games (Nintendo Wii) were used for the practice. Each group was composed of eight participants, paired up by gender and age, TD (M = 111.87 months; SD = 4.05) and pDCD (M = 115.87 months; SD = 4.96). The TD group participated in seven practice sessions and the pDCD group participated in eleven sessions. Results regarding performance on Wii console games showed significant improvement from the first day of practice to the last day in both groups (pDCD and TD). A higher volume of practice for children with pDCD compared to their TD peers helped to increase the performance of the former group. Therefore, the pDCD group achieved a performance similar to the TD group in both practiced games.

title: Level of physical activity and associated factors in a public university

description: Abstract The aim of the present study was to investigate the level of physical activity and associated factors of the academic community of a Brazilian federal higher education institution. Overall, 483 students, 49 teachers and 153 administrative technicians of both genders participated in this stdy. Sociodemographic questionnaire, BMI evaluation and classification of the level of physical activity (IPAQ) were used. Statistical analysis was performed by the Pearson Chi-square test to observe possible associations between independent variables and LPA and Poisson regression analysis with 95% confidence intervals through the SPSS software version 22.0. Among the 61.8% of individuals classified as physically active, 48.90% belonged to the health area and 52.40% had Graduation / Specialization level. Of these, 45.7% showed normal BMI and 62.2% of them did not practice exercises before being admitted to the extension project. Teachers and administrative technicians were, respectively, 3.62 (95% CI = 1.11-11.82) and 2.15 (95% CI = 1.03-4.66) times more likely of having sedentary behavior when compared to the group of students. LPA was higher in undergraduate students, while teachers and technicians were more likely of being sedentary. The majority of participants had normal BMI and the largest portion of physically active individuals was composed of students of the health area. Thus, it is necessary to encourage interventions for the practice of physical activity within the academic community, as well as the implementation of internal policies to mobilize individuals to improve the worrying situation of sedentary behavior.
