This was a cross-sectional study that aimed to evaluate the association between breastfeeding and motor development of infants at 3-4 months of age in the city of Pelotas, Rio Grande do Sul. The outcome, infant motor development, was evaluated through the Bayley Scale of Infant Development (Bayley III). The prevalence of infants that stopped…

The dynamics of mastering the degrees of freedom in motor learning are still far from being understood. The present work explored coordination dynamics in a redundant task, relating it to performance and adaptation in a serial stimulus tracking task. One hundred and sixty-three children (10-14 years of age) continuously responded to sequential…

Purpose: To analyze associations between physical activity (PA) during school hours and fundamental movement skills (FMS) of young children with and without PE classes. Methods: This cross-sectional study examined 201 children of both sexes (102 girls, 50.7%), aged 3-5 years old (4.51 ± 0.79), who were engaged (n = 129) or not (n = 72) in physical…

The typical process for assessing inter-rater reliability is facilitated by training raters within a research team. Lacking is an understanding if inter-rater reliability scores "between" research teams demonstrate adequate reliability. This study examined inter-rater reliability between 16 researchers who assessed fundamental motor…

Knowledge of results (KR), particularly its informational role, has often been regarded as redundant for learning interception-like tasks, such as coincidence-anticipation timing tasks. However, it is possible that the KR's guiding effect might be detrimental to motor adaptation, instead of only redundant, leading to a dependency on KR and…

Different individuals learn different solutions to the same perceptual-motor task regardless of the fact that they may undergo the same practice conditions. In the current study, we characterized individual solutions to a perceptual-motor task. Eighteen self-declared right-handed participants were requested to intercept a moving target controlling…

Background: Smartphones are a resource noticeably inserted into people's daily lives, but they are not nearly as present within the various educational systems around the world. The improper use of smartphones can certainly carry some risks, such as a sedentary lifestyle or even addiction. For the aforementioned reasons, promoting literacy by…

We aimed to investigate the impact of smartphone use during intertrial intervals within a distributed practice regime on mental fatigue, performance, and learning of a balance motor skill. One hundred and thirty-six participants were randomly divided into two groups: the smartphone use group (SMARTPHONE) and the control group (CONTROL). The…

Fundamental motor skills (FMSs) are building blocks for future movements and may vary according to cultural context. Moreover, network analysis can identify which skills contribute most to an overall set of skills. This study identified the most influential FMS in samples of U.S. and Brazil preschoolers that may contribute to a pattern of adequate…

The objective of this study was to verify the effects on 4- to 18-month-old babies' NPMD after the family-centered Kids Intervention Therapy -- Aquatic Environment (KITE) programme. This quasi-experimental study involved 61 families. The NPMD was assessed with Alberta Infant Motor Scale (AIMS), Denver II Developmental Screening Test, context…

Background: The Test of Gross Motor Development--3 (TGMD-3) is used to assess locomotor (LOCS) and ball (BS) skills in children. This test provides relevant information for evaluating learning and determining teaching efficacy. However, conducting and coding the test is time consuming. A screening form may improve its usage in specific settings…

Background: Studies related to the motor performance of children have suggested an interaction between organisms and the environment. Although motor development seems to be similar among people, the behavior is specific to the context that people are part of. Thus, the aim of this study was to compare the fundamental motor skill performance…

Learning to descend stairs requires motor and cognitive capacities on the part of infants and opportunities for practice and assurance of safety offered by caregivers. The American Academy of Pediatrics prescribes the age strategy to teach toddlers to safely descend stairs but without much consideration for individual differences in infants'…

Background: Children living in poverty often are exposed to situations that negatively affect various aspects of their development. So, it is important to propose interventional programs that minimize the negative effects of living in poverty on these children. Objective: To verify the impact of a mastery climate cognitive-motor skills…

The aim was to evaluate the effects of a family-focused early intervention programme on the cognitive, motor, and language development of infants exposed to social and biological risks in the first year of life. Quasi-experimental randomized controlled trial (RBR-6ct969), with intervention (IG; n = 72) and control (CG; n = 170) groups. IG mothers…
