However, it is unknown whether motor coordination level can predict performance on volleyball skills. The main aim of this study was to verify whether motor coordination level, assessed using a generic test, can predict performance on volleyball skill sin youth. Material and methods: A total of 34 adolescent students (mean 14.4± 0.3 years) were recruited. The KörperkoordinationtestFür Kinder (KTK), a generic, non-sport specific test, composed by four tasks (i.e. dynamic balance, hopping, agility and moving sideways skills) was used to assess motor coordination level. Motor performance on volleyball skills was assessed on the basis of two product-oriented tasks: underhand volleyball serve and volleyball serve receiving. A single measure representing the volleyball skills of the participants was adopted. Linear regression models were executed. Results: Regression analysis revealed ...

Yet, the prevalence of adolescent overweight/obesity is high, and it is unknown whether low levels of motor competence are a risk factor. The purpose of this study was to assess whether adolescents with low motor competence are at increased risk of overweight/obesity. Methods: A total of 142 adolescents (47.2% boys) aged 12-14 years were recruited from Rio de Janeiro, Brazil. Motor competence level was assessed using the Körperkoordinationtest fur kinder (KTK) and classified in two categories: "low" and "adequate." BMI measures were used to classify weight status as "healthy" or "overweight/obese." The correlation between motor competence level and BMI was tested. A binary logistic regression model was executed adjusting for potential confounders (age, sex, and stature). Results: Motor competence was moderat...

To date, it is unclear whether these variables reciprocally influence each other over time. We assessed whether and how MC, PA and body composition influence each other across adolescence. In a longitudinal study with 14 months of follow-up, we recruited 166 adolescents aged 12–13 years. We recorded participants’ self-reported PA and body fat percentage and assessed their MC using the Körperkoordinationstest für Kinder (KTK). We used linear mixed models and mediation analyses with crude and adjusted (age, sex, time point) models to examine associations among the selected variables across time. MC showed a bidirectional relationship with both PA ( p

Buscamos diálogo com os estudos pós-estruturalistas, sobretudo nas teorizações de Jacques Derrida e Judith Butler, pelas noções de performatividade da linguagem e performatividade de gênero. Além disso, propomos a construção de dados pela produção de narrativas com os treinadores, pelos princípios de Leonor Arfuch e Jorge Larrosa, na operacionalização de entrevistas dialógicas por meio de conversas. Os treinadores enunciaram sentidos diversos, que remetiam ao preconceito e não aceitação das jogadoras nas equipes de voleibol, em particular os que atuavam na categoria profissional, como da inclusão das mesmas, ainda que dentro de determinados parâmetros. Acreditamos que novas pesquisas sobre a participação de transgêneros no esporte podem tensiona...
