title: Muscle quality, but not muscle thickness, is decreased in different age groups of active older women

description: Abstract The aim of this study was to compare the muscle thickness (MT), muscle quality (MQ), and functionality of two different age groups of active elderly women. Twenty seven older women (between 60 and 80 years old), physically active was dividing in two age groups: old 60-66 years (Old) and old 73-80 years (Older) volunteered for the present study. Knee extension isometric peak torque (PT) was obtained during a muscle isometric voluntary contraction (MIVC), and the value was normalized by MT. The Quadriceps Echo Intensity (QEI) was defined as the mean Echo Intensity (EI) value founded in all quadriceps muscle portions in ultrasound imaging. Was found MIVC increased (p=0.024) in the O1 (120.26±24.77 N/m) group when compared with the O2 (99.25±20.95 N/m) group, but when the MIVC was normalized the difference did not exist between groups (p≥0.05). The QEI was found increased in the Older group (97.10±17.35 a.u.) when compared with the Old group (80.18±14.95 a.u.) (p&lt;0.05). Contrary to that, the QMT did not differ significantly between the groups (p≥0.05). The Old group presented a significant higher number of repetitions in the 30SS (14.13±2.29 repetitions) when compared to Older group (11.25±1.95 repetitions) (p&lt;0.05). We observed that even without significantly greater muscle size, the Old group presented the results of 30SS significantly greater when compared with the older group. Besides that, the QEI was found increased in the older group and suggests that EI may be the best predictor of functional capacity than muscle quantity in active older woman.

title: Aspects of flexibility of women with fibromyalgia syndrome

description: Abstract Regular physical exercise tends to benefit people with fibromyalgia syndrome (FMS). The effects have been observed regarding aerobic power and strength; however, results concerning flexibility have been controversial. In general, studies have evaluated specific joints or tests involving only a single body movement. The aim of this study was to compare the flexibility profile of FMS and asymptomatic women using a more comprehensive test protocol regarding the number of movements and joints involved. The sample consisted of 30 women divided into two groups: asymptomatic (n = 15; mean age: 50.2 ± 8.2 years; mean weight: 63.0 ± 9.6 kg; mean height: 157 ± 6 cm) and fibromyalgia (n = 15; mean age: 47.3 ± 9.4 years; mean weight: 61.9 ± 12.2 kg; mean height: 159 ± 7 cm). Flexibility was measured using the Flexitest, which was evaluated by the global index of flexibility (Flexindex), and the five indices of variability of joint mobility: intermovement (IVIM), interjoint (IVIA), flexion-extension (IVFE), between segment (IVES) and distal-proximal (IVDP). All of the indices were calculated based on the results of the 20 movements of the Flexitest. There was no difference between groups (44.4 ± 3.7 vs. 45.7 ± 4.1 points, for asymptomatic and fibromyalgia, respectively; p = 0.379; 95% confidence interval (CI): -4.2 to 1.6). Most of the sample (83%) showed an average level of flexibility based on reference values for gender and age. Only IVIM showed a significant difference between the groups. Asymptomatic and fibromyalgic women have similar overall levels of flexibility but with different profiles.

title: Association between unhealthy behavior and sleep quality and duration in adolescents

description: Abstract Inadequate sleep has been associated with unhealthy behavior in adolescence. This study aimed to estimate the prevalence of negative sleep indicators (perceived poor-quality sleep and insufficient sleep duration) among students and to identify unhealthy behaviors associated with this outcome. This study is part of a school-based, cross-sectional survey conducted in 2011 in adolescents from Santa Catarina State, Brazil. High school students aged 15 to 19 years (n = 6,529) and enrolled in state public schools participated in the study. The students responded to a questionnaire on the number of hours slept (insufficient: &lt; 8 h, sufficient: ≥ 8 h); perceived sleep quality (good or poor); and behavioral variables. Multinomial logistic regression was performed using reports of positive sleep indicators, and negative reports of one or two sleep indicators. Approximately 30% of adolescents reported a negative perception of sleep, indicating poor quality and insufficient duration. The use of computers/videogames (≥ 4 h/d) and excessive consumption of alcoholic beverages, salty snacks or sweets were associated with negative sleep indicators. A high number of young people displayed one or two negative sleep indicators, and it was found an association between these indicators and a number of unhealthy behaviors.

title: Length of stay of elderly in a Community Physical Activity Program and Associated Factors

description: Abstract The registration or insertion of older adults in Community Physical Activity Programs does not guarantee their stay over time. The purpose of this study was to analyze the length of stay of elderly in a Community Physical Activity Program and associated factors. This epidemiologic observational study of retrospective cohort performed in Aracaju City, Brazil, included a sample of 526 older adults (477 females) aged 66.4 ± 5.4 years. To characterize the profile and length of stay of individuals, descriptive statistics was used. To analyze the length of stay, the Kaplan-Meier non-parametric survival, estimator was used. To verify the association between variables in the observed time, the Cox regression model was applied. Inverse ratio equation (1/OR) was used to facilitate the understanding of significant values when necessary. In all analyses, 95% confidence interval and p≤0.05 were used. In the first three months, stay rate of 58.1% (95% CI = 54.6 - 61.3) was observed, with a risk estimative = 41.82%. Females presented a 45% chance of stay (OR = 0.69; 95% CI = 0.51 – 0.93) and individuals identified with osteoporosis had 32% more chances of stay (OR = 0.74, 95% CI, = 0.60-0.91). Only 1% of subjects remained until the end of the cohort. The stay rate was low throughout all series; the period with higher quitting rates was the 3rd and the 12th months, being associated with the female stay sex and undiagnosed osteoporosis.

title: Sport classification for athletes with visual impairment and its relation with swimming performance

description: Abstract The medical classification (MC) adopted for swimmers with vision visual impairment (VI) does not clearly elucidate the influence of vision loss on performance. In a documentary research, the final time in the 50-, 100- and 400-m freestyle events and MC (S11, S12 and S13) of national (n = 40) and international (n = 72) elite swimmers was analyzed. The analysis was performed using the Kruskal-Wallis test and Spearman’s correlation with 95% confidence (P &lt; 0.05) and Cohen’s d was calculated. There was a large effect of MC on the final time in the 50-m (P = 0.034, d = 1.55) for national athletes and in the 50-m (P = 0.001, d = 2.64), 100-m (P = 0.001, d = 3.01) and 400-m (P = 0.001, d = 2.88) for international athletes. S12 and S13 classes were faster compared to S11 class for all international events, but only in the 50-m for the national event (P &lt; 0.05). It was found a strong negative relationship between the final time and MC for international athletes (Spearman’s Rho ≥ 0.78). There was a significant influence of MC on the performance of swimmers in freestyle races, especially in international swimmers. Thus, having a visual residue seems to be sufficient for S12 and S13 swimmers to achieve similar performance.

title: Hierarchy of physical education goals as an expression of educational priorities among Polish teachers

description: Abstract The work of teachers has to be purposeful and well thought out in order to achieve desired results. Both theory and practice show that achieving success is combined with the adequate setting of educational goals and organizing them in a specific hierarchy. The objective of this study was the diagnosis of preferences concerning the hierarchy of physical education goals. A questionnaire developed by the European Physical Education Association was used as the research tool. Teachers perceived the goal of 'encouraging students to lead an active, healthy lifestyle' as the most important consideration. Its realization should result in lifelong physical activity and healthy lifestyle among students. From the results of this study it can be concluded that the following priorities of Polish teachers of physical education can be identified: health and physical fitness of pupils. Goals connected with shaping the social competences of pupils ranked lowest in importance.

title: Prevalence and factors associated with sarcopenia in elderly women living in the community

description: Abstract The objective of this study was to identify the prevalence of sarcopenia and factors associated with it in a population of elderly women living in the community in the Northeast of Brazil. This was a cross-sectional study of 173 women aged 60 years or older living in the urban zone of the municipality of Lafaiete Coutinho, Bahia, Brazil. Associations between sarcopenia (defined as reduced muscle mass plus reduced muscle strength and/or reduced muscle performance) and independent variables including sociodemographic characteristics, behavioral variables and health status were tested using logistic regression techniques. The significance level was set at 5%. The prevalence of sarcopenia in the study population was 17.8%. The logistic regression technique only identified the variables advanced age (p = 0.005) and hospital admission during the previous 12 months (p = 0.009) as statistically significant. It was concluded that there was a significant prevalence of sarcopenia among elderly women resident in a community with unfavorable health conditions and the findings showed that the strongest associations were with age over 80 years and hospital admission during the previous 12 months.

title: Effect of tapering on anaerobic power and capacity of tae-kwon-do athletes

description: Abstract The aim of the study was to analyze the effect of a tapering period on anaerobic power and capacity of tae-kwon-do athletes. Thirty-one male tae-kwon-do participants of the Brazilian Championship were selected in a non-probabilistic way. Subjects were randomly divided into two groups, namely: experimental group (EG, n = 15) and control group (CG, n = 17). Both groups followed the same training protocol up to the tapering stage. CG was submitted to training loads contained in the last two weeks of the macrocycle. Only EG was submitted to tapering. Tapering had 2 weeks duration, adopting the linear tapering method. Taekwondo Anaerobic Test was performed by athletes before the start of the season, which was named as pre-intervention, and the last week of each mesocycle [Prep I, Prep II and Tapering (only EG)]. Group vs. time effect interaction (p &lt; 0.01) was identified for alactic anaerobic power, with an increase only in EG in tapering (p = 0.01). A significant group vs. time interaction (p &lt;0.01) was revealed to fatigue index, improved anaerobic capacity being checked in EG only after the tapering period (p = 0.01). It was concluded that two weeks of linear type tapering optimized the anaerobic power and capacity of male tae-kwon-do athletes.

title: Tactical behavior in soccer small-sided games: influence of team composition criteria

description: Abstract This study aimed to compare the tactical behavior of young soccer players during small-sided games played with team composition criteria based on procedural tactical knowledge, aerobic power and speed performance. Eighteen male soccer players played 3vs.3 small-sided games with teams balanced according to players’ performance on Sprint Test, Yo-Yo Intermittent Recovery Test and the field test of the System of Tactical Assessment in Soccer. Data related to the incidence of tactical principles were analyzed through the proportions chi-square test with Bonferroni’s correction. One-way ANOVA was used to compare players’ offensive and defensive tactical performance. Results showed different incidence of offensive and defensive tactical principles in games with different teams’ composition criteria. It has also been shown a higher defensive performance when the teams’ composition criteria was based on players’ procedural tactical knowledge.
