title: Patellofemoral pain and sports practice: reduced symptoms and higher quality of life in adolescent athletes as compared to non-athletes

description: Abstract Patellofemoral pain (PFP) is common in athletes and physically active individuals and it is one of the most frequent knee disorders among adolescents. However, the impact of the severity of PFP symptoms on quality of life (QOL) has been barely investigated. Thus, we aimed to compare the level of PFP and the self-reported QOL between adolescent athletes and non-athletes, and to explore the relationship between the severity of PFP symptoms and QOL. Fifty-six adolescents with PFP (22 athletes and 34 non-athletes) were asked to fulfill the Anterior Knee Pain Scale (AKPS) and the QOL dimension of the Knee Outcome in Osteoarthritis Survey (KOOS). Between groups comparisons indicated that adolescent non-athletes presented higher severity of PFP symptoms and lower QOF as compared with adolescent athletes. Significant correlations between the severity of PFP and QOL were found for both groups, regardless of the athletic status.

title: Aging male symptoms: the relationship between physical activity and quality of life

description: Abstract Objective To examine the relationship between physical activity (PA) and the aging male symptoms of middle-aged men in the quality of life (QOL). Methodology: Cross-sectional study with a probabilistic samples of 416 men (40-59 years old), all residents in two cities in southern of Brazil. A questionnaire was used. The studied population was divided into two groups: with and without symptoms. The analyses were carried out in a descriptive and inferential approaches. Results: Aging male symptoms were related to QOL. Men who perceive their overall QOL as good presented a13% lower probability of (95%CI = 0.77-0.98) being insufficiently active. For those with symptoms, QOL scores were higher in social and environmental domain in PA between 30-60 min/day, and the physical domain for more than 60min/day. Conclusion: Our findings show the importance of PA to achieve significant benefits in QOL and health of men in middle age with aging male symptoms.

title: Technical-tactical performance profile of the block and dig according to competition category in men's volleyball

description: Abstract The aim of this study was to analyse the technical-tactical performance profile of blocking and court defence actions for various age groups and categories of competition in men's volleyball. The sample comprised 16,454 blocks and 8,321 digs performed in 299 sets in several categories of competition (from U-14 to Olympic Games). A descriptive and correlational inter- and intra-group observational design was used. The variables studied were: category of competition, opponent's spike tempo, and block and dig performance. The results showed a significant increase in the percentage of blocks and digs derived from fast attacks and a significant improvement in performance of these actions to counteract slow attacks. Thus, improving in blocking and digging performance was observed at higher categories when the attack is performed slowly. This paper discusses various reasons for the evolution in defensive performance and the effects on the training process for various categories of competition in volleyball.

title: Comparison of different ways of expressing creatine kinase concentration of soccer players during a competitive season

description: Abstract The aim of this study was to analyze the responses of creatine kinase [CK] expressed in different forms to the training load of professional soccer players during a competitive season. Twelve players (age, 24 ± 4 years) participated in the study. [CK] was analyzed before the pre-season (Pre), after the pre-season (Post), and in the competitive mesocycles (M1, M2, and M3). Results showed [CK] in the Pre, Post, M1, M2, and M3 phases in absolute values (181.3 ± 58.7, 416.4 ± 155.7, 526.4 ± 268.0, 403.8 ± 137.0, and 442.5 ± 212.3 U/L, respectively), relative values (16.3 ± 4.6, 39.5 ± 19.1, 47.8 ± 20.1, 37.5 ± 14.2, 40.1 ± 17.4 %CKmáx, respectively), and values relative to the variation delta (19.9 ± 3.6, 48.1 ± 26.5, 57.0 ± 23.2, 45.1 ± 17.7, and 48.3 ± 22.0 %ΔCKmáx, respectively). [CK] was lower only during the Pre phase compared to the other phases (p &lt; 0.05). [CK] was expressed as %CKmáx or %ΔCKmáx may be more specific to monitor training. In addition, the individualization of this biomarker optimizes the athletes' performance as muscle injuries can be prevented.

title: Teacher efficacy beliefs during the practicum experiences in physical education classes

description: Abstract Previous studies focusing on teacher education have highlighted the role that supervised practicum plays in the construction of future teachers' personal beliefs, including self-efficacy beliefs, yet there remains a need to understand which learning experiences contribute to the constitution of this belief during the supervised practicum. Our objective was to identify situations that influenced student teachers' judgment of self-efficacy during the development of supervised practicum. This exploratory and descriptive documentary research analyzed 18 reflective portfolios produced by student teachers' during their supervised practicum in a physical education teaching program course. The experience of teaching in locus and the opportunity to experience everyday school-life were recurring situations in 15 out of the 18 analyzed portfolios. The results led us to believe that offering student teachers the possibility to meet and experience the teaching environment in advance contributed positively, through enactive mastery experiences, to the building of their self-efficacy beliefs concerned to teaching.

title: Postural balance in Alzheimer's disease patients undergoing sensory pitfalls

description: Abstract Despite consensus regarding the interference of cognitive processes on the human balance, the impact that different sensory stimuli have on the stabilometric measures remains unclear. Here, we investigated changes in the postural balance of individuals with Alzheimer's disease (AD) and in healthy controls undergoing different proprioceptive and somesthetic pitfalls. We included 17 subjects submitted to eight sensorimotor dynamics with differences in the support bases, contact surfaces, and visual clues. The measurements used to assess participants balance were as follows: position of the body in space, range of instability, area of the support base, and velocity of postural control. From a total of 56 cross-sectional analyses, 21.42% pointed out differences between groups. Longitudinal analyses showed that tasks with proprioceptive and somesthetic pitfalls similarly impact imbalance in both groups. The current results suggest that AD subjects and healthy controls had different patterns submitted to balance, but suffered similar interference when undergoing proprioceptive and somesthetic challenges.

title: Assessment of motor skills and school performance in children diagnosed with attention deficit hyperactivity disorder

description: Abstract This study was designed to analyze the association between motor skills and school performance in elementary school children with attention deficit hyperactivity disorder (ADHD). Two groups of children were evaluated. The experimental group contained 55 students of both sexes, age 7 to 10, who had been clinically diagnosed with ADHD; the control group consisted of 55 children with typical motor development. The results showed no association between motor skills and school performance in the experimental group, although there was a statistically significant difference between manual dexterity and writing performance in the control group. Although we found no relationship between motor skills and school performance in children with ADHD, we believe that having specialized professionals monitor these children may be beneficial. Early diagnosis of impaired motor skills and poor school performance may lead to better developmental opportunities and a better quality of life.

title: Postural Sway Parameters and Gait Symmetry in Preschool Children: Cross-sectional study

description: Abstract The most important function of posture is to ensure the maintenance of control during the start and the continuation of human movement, moreover, posture serves as a reference for the production of precise movements. The aim of this study was to relate the postural sway parameters and gait symmetry in preschool children.This study is a cross-sectional study, conducted in 49 children with a mean age of 4.65 ± 0.44 years. Initially, height and body mass of children were measured using anthropometric scales. Next, an electronic baropodometer was used to evaluate the distribution of dynamic plantar pressure (gait) and stabilometry (balance).A Student t test or Mann-Whitney test for comparing two groups was used. To correlate variables, a Pearson's correlation or Spearman's correlation coefficient was used. The stabilometric parameters showed no significant difference between an eyes open test and eyes closed test in preschool child. We found a moderate relationship between axis inclination and cadence symmetry (R=0.40;p=0.007). Postural sway parameters have relationship cadence symmetry of the gait in preschool children.

title: Anthropometric analysis and performance characteristics to predict selection in young male and female handball players

description: Abstract The aim of this study was two-fold. The first aim was to determine if there were any anthropometric and physical performance differences (controlling for maturation) between male and female handball players selected in training categories as well asthe relation of these differences with the performance level achieved. The second aim was to identify the discriminatory variables between the performance levels achieved. A total of 216 young handball players (125 men and 91 women) participated in the study. The data were classified by selection level (regional n=154; national n=62), gender (men; women) and age category (under-15; under-17). The use of MANCOVA analyses, controllingfor maturation, identified how gender could determine variables related to handball players' future competitive levels. The results revealed that anthropometric variables such as height, arm span, trochanter height, thigh girth, and leg girth were more influential in men than in women. In addition, the physical performance tests of vertical jump (squat jump and counter movement jump with/without arm) and 10x5m shuttle run were determinants in both sexes. Discriminatory analysis predicted that a combination of five variables (counter movement jump with arm, body mass, 10x5m shuttle run, dominant hand length and trochanter height) would successfully distinguish between regional and national players, with a predictive accuracy of 81.9% for all players.

title: Sports Practice and Bone Mass in Prepubertal Adolescents and Young Adults: A Cross-sectional Analysis

description: Abstract AIM To compare bone mass and body composition variables between adolescents engaged in high-impact sports and adults who were sedentary during early life. METHOD A cross-sectional study with 155 participants (64 adolescents and 91 adults) aged between 11 and 50 years old. Among the adults, history of sports was evaluated during face-to-face interviews, and information regarding the adolescents' training routines was provided by their coaches. Body composition was evaluated using Dual Energy X-Ray Absorptiometry which provided data about bone mineral density (BMD), bone mineral content (BMC), fat mass (FM), and free fat mass (FFM). RESULTS Adults who engaged in sports practice during early life had higher values of BMC (ES-r = 0.063), FFM (ES-r = 0.391), and lower values of FM (ES-r = 0.396) than sedentary adults. Higher values of BMC (ES-r = 0.063) and BMD in lower limbs (ES-r = 0.091) were observed in active adolescents. Adolescents engaged in sports and adults who were sedentary in early life presented similar values in all bone variables, FM, and FFM. CONCLUSIONS Sports involvement in early life is related to higher bone mass in adulthood. Adolescents engaged in sports presented similar bone mass to adults who had been sedentary in early life.
