title: DISCRETE MOTOR SKILL ACQUISITION: EFFECT OF NUMBER OF VISUAL DEMONSTRATIONS

description: ABSTRACT This experiment investigated the effect of number of visual demonstrations on the acquisition of discrete motor skill. Seventy-four college students of both sex participated in this study. The participants observed a visual model twice or ten times. In the acquisition phase, the participants were asked to throw a dart with postero-anterior movement into a circle target until reach a learning criterion. In transfer tests no difference between groups was found in the analysis of score. However, ten demonstrations were more effective than twice as regards performance of the correct pattern of movement and the number of subjects who reached the performance criterion. The results indicate a similar effect of the both number of demonstrations in the performance and dart throwing learning and both conditions influence subject’s capacity to detect relevant information to perform the task.

title: EVALUATION PRACTICES OF PHYSICAL EDUCATION TEACHER: INVENTING POSSIBILITIES

description: ABSTRACT The present study aims to offer and analyze concrete possibilities of evaluation practices for School Physical Education. It assumes, as a theoretical-methodological approach, the narrative (auto) biographical and has as collaborators two Physical Education teachers. The research has as sources: evaluative records produced with the children (drawings, photographs, song lyrics) and teachers' narratives. The results show that a teacher has been based on an evaluation for the students' learning, inventing instruments that enabled her to understand the appropriations of the students of the specific knowledge of Physical Education; And another teacher centralizes her evaluation in the teaching and learning practices, producing instruments that allowed the self-evaluation of those involved.

title: WHAT IS THE NUMBER ATTEMPTS ARE NECESSARY TO EVALUATE POSTURAL CONTROL ON A FORCE PLATFORM IN HEALTHY CHILDREN?

description: ABSTRACT The standardization of the assessment of postural control on the force platform will facilitate the conducting of studies in children. There is no standardization for the child population, making it difficult to compare results.The present study aimed to determine the number of attempts needed for the assessment of postural control on a force platform in healthy children. A total of 344 children, 178 (51.7%) girls, eight years old, participated in this study. Postural control was evaluated with a single leg stance for 30 seconds, the present study analyzed pressure center displacement area (COP) and velocity anteroposterior and medial-lateral (Vel. AP and Vel. ML). For the comparative analysis of postural control with three attempts we used the Friedman test. Results were analyzed using the intraclass correlation coefficient and Bland-Altman concordance test. No significant differences (p &gt;0.05) were found in the three evaluation. One attempt by the child proved to be sufficient to evaluate the COP, Vel. AP and Vel. ML (p =0.139; p =0.718; p =0.05, respectively). Excellent reproducibility was observed in the COP and Vel. ML variables (ICC:090, p &lt;0.0001, Error:0.07 cm2; ICC:0.91, p =0.001, Error:0.024 cm / s, respectively) and average replicability in variable Vel. AP (ICC:0.68, p =0.0001, Error:0.10 cm / s). The present study recommends one attempt is sufficient to assessment of postural control in healthy children.

title: ACUTE EFFECTS OF PHYSICAL EXERCISE AT DIFFERENT INTENSITIES ON INFLAMMATORY MARKERS IN OBESE ADOLESCENTS

description: ABSTRACT Obesity promotes a state of chronic low-grade inflammation of white adipose tissue, which is associated with different chronic diseases. While exercise induces an anti-inflammatory environment, little is known about the acute effects of continuous exercise at different intensities on inflammatory markers in obese adolescents. This study included 10 obese adolescents of both sexes, between 15 and 18 years of age. Volunteers performed two 30-minute exercise sessions. The 1st exercise session was performed at moderate intensity (55% VO2peak) and the 2nd at vigorous intensity (75% VO2peak), with a one-week interval between sessions. Blood samples were collected 10 minutes before and 20 minutes after the exercise sessions. Inflammatory markers were analyzed using the chemiluminescence method. Statistical analysis was performed using the two-factors ANOVA test for repeated measures and statistical significance was set at 5% (p &lt;0.05). The results showed that 30 minutes of moderate aerobic exercise resulted in significant changes in circulating levels of TNF-α (6.23 ± 1.64 to 7.03 ± 1.49) and IL-6 (3.35 ± 1.53 to 3.85 ± 1.73). The results of this study showed that a single exercise session of moderate intensity lasting for 30 minutes induced acute responses in inflammatory markers in the obese adolescents evaluated.

title: RATING SCALE FOR QUALITY OF SERVICES PROVIDED BY gyms (QUASPg)

description: ABSTRACT In order to identify factors that interfere with gym clients’ choice, permanence and withdrawal, the aim of this study was to build and validate an instrument to assess the quality of services provided by gyms. The study has four stages (question identification, evaluation of the analysis matrix clarity, importance and relevance, reliability analysis on instrument questions, and question analysis as to the instrument construct). A total of 51 criteria were identified and deemed important for service quality. The Analysis Matrix was composed of the following dimensions: structure, management, marketing and accessibility. The question and matrix evaluation ruled out 19 questions. The reliability evaluation excluded one question and the accessibility dimension. The Confirmatory Factor Analysis model evidenced adequate goodness of fit after the exclusion of eight questions and performance of six correlations. Composite Reliability, Average Variance Extracted, Discriminant Validity, and Cronbach’s alpha showed acceptable values. Thus, it is concluded that the instrument called “Rating Scale for Quality of Services Provided by Gyms” (QUASPG) has satisfactory psychometric properties, being composed of 21 questions distributed into three dimensions, namely: Environment, Management and Marketing.

title: PHYSICAL ACTIVITY IS ASSOCIATED WITH KNOWLEDGE AND ATTITUDES TO DIABETES TYPE 2 IN ELDERLY

description: ABSTRACT The aim this study was examined the association between physical activity, sociodemographic variables, health conditions and disease knowledge and attitudes in older adults with type 2 diabetes (DM2). A questionnaire for the collection of sociodemographic data and health conditions, the International Physical Activity Questionnaire (IPAQ), Diabetes Knowledge Scale (DKN-A), and Diabetes Attitude Questionnaire (ATT-19) were applied to 204 older adults. The absolute and relative frequencies was obtained and the results were analyzed by the chi-square test for proportions, bivariate analysis and logistic regression (p≤0.05). Significant associations were observed between being physically active and age above 70 years (OR=0.40; 95%CI: 0.22-0.90), having good knowledge of DM2 (OR=12.7; 95%CI: 6.8-30.1), and having a positive attitude towards DM2 self-care (OR=10.1; 95%CI: 6.34-20.1). Physical activity is associated with greater knowledge and a positive attitude towards DM2 self-care.

title: COMPARISON OF THE STROKE PARAMETERS BETWEEN FRONT-CRAWL SWIMMING AND SWIM BENCH

description: ABSTRACT The swimming bench has been used as complementary training in swimming, however, there are no studies that analyze in three dimensions the specificity movement applied by this land-based swimming simulator. The aim of the study was to compare the stroke parameters of front-crawl swimming and swim-bench, as well as movement symmetry. Ten swimmers (16 ± 1.4 years) were filmed in a real swimming condition (50m) and a 30s swim bench stroke simulation using four GoPro Hero 4 cameras. Stroke dimensions, hand speed in the underwater phase and hip displacement were analyzed. Comparison between tests and sides symmetry was performed by two-way repeated measurements ANOVA and stroke rate between the tests was analyzed by Student's t-test. Swimmers showed a symmetrical characteristic in both conditions which indicates high body control and proficiency. The stroke dimensions differed between tests, mainly explained by the displacement limitation, trunk and hip rotation in the swim bench. The stroke rate and underwater hand speed pattern were similar (p&gt; 0.05) and partially justify the use of this equipment as complementary land-based training, evaluation and control of the swimmers performance.

title: ACUTE EFFECT OF WHOLE BODY VIBRATION IN THE UPPER LIMBS STRENGTH

description: ABSTRACT The aim of this study was to investigate, from a protocol of maximal isometric contractions of the elbow flexors, the effect of WBV in the maximal force and of impulse in strength-trained individuals. Twenty male volunteers, age: 23.8 ± 3.3 years, performed 3 sessions (one familiarization session and two intervention session). The sessions were composed by 3 MVC of the elbows flexor muscles with 5 minute of rest between them. The first CVM was performed without vibration and the others, applying aleatory WBV with 10, 20, 30, 40Hz, and amplitude of 6mm. The results showed that the maximal force and of impulse obtained during the MVC without vibration was significantly higher than the maximal force and of impulse recorded during the application of WBV. For strength training, the application of WBV, in the adopted frequencies, was not able to generate sufficient stimulus to induce acute adaptations in muscle strength of upper limbs.

title: CARDIOVASCULAR RESPONSES AFTER ISOMETRIC HANDGRIP EXERCISE AT DIFFERENT INTENSITIES IN HEALTHY MEN

description: ABSTRACT The 30% maximal voluntary contraction protocol for isometric handgrip exercise is widely used to improve the cardiovascular system. However, it is unknown whether intensity modulation affects these responses. Objective: To analyze acute cardiovascular responses after isometric handgrip exercise performed at different intensities. Twenty-three healthy men participated in this cross-over study. The volunteers performed three experimental sessions: 4x2 minutes of contraction at 30% (S30) MVC and 4x2 minutes of contraction at 50% (S50) MVC, besides control (CS). Blood pressure (BP) as well as time (SDNN, RMSSD and PNN50) and frequency (LF, HF and LF/HF) domain heart rate variability parameters were obtained before and after sessions. None of the experimental sessions promoted statistically significant changes in systolic and diastolic BP (p&gt; 0.05 for all). After S50, there was a smaller increase in SDNN five minutes after the exercise (S50: +5±6, S30: +20±5, SC: +10±2 ms, p &lt;0.05) and higher LF/HF after 20 minutes (S50: +1.59±0.80, S30: -0.49±0.49, SC: +0.39±0.49, p &lt;0.05) compared to the other sessions. In conclusion, BP responses to isometric handgrip exercise are similar between intensities; however, the most intense exercise promoted a greater increase in sympathetic modulation and decrease in parasympathetic modulation after exercise.

title: THE ROLE OF SPORT PARTICIPATION AND BODY MASS INDEX IN PREDICTING MOTOR COMPETENCE OF SCHOOL-AGE CHILDREN

description: ABSTRACT The purpose of this study was to investigate the association between Sport Participation (SP) and Motor Competence (MC) in school-age children, and to assess the mediation role of Body Mass Index (BMI) on this association. 707 children (332 boys, 375 girls) aged between 6- to 10 years participated in the study. Motor competence was determined using the Bruininks-Oseretsky Test of Motor Proficiency (BOT-2). Parents were asked about organized SP, categorized as 1) no participation, 2) partial participation and 3) consistent participation, and BMI was calculated based on the child’s height and weight. The results indicated significant differences for all MC components and total score for SP categories, all p &lt; .05, with higher results for consistent participation in sports. For BMI, significant differences occurred in all components, with the exception of fine manual control and manual coordination. Our findings showed that SP was associated with MC, and BMI was not an important factor in these relationships. However, a small mediation of BMI was found, but only for obese children. In summary, we conclude that sport participation plays a relevant role in the development of motor competence in school-age children, and that association is, in general, not mediated by weight status.
