Background: Early childhood development (ECD) practitioners are essential in governing foundational aspects, such as gross motor development and participation in physical movement. Aim: This study aimed to determine ECD practitioners in Vanderbijlpark's awareness of gross motor milestone acquisition and movement guidelines for children birth to 4…

Infant motor development is affected by the sociocultural context in which it takes place. Because societal and cultural practices are dynamic, this exploratory study examined whether the ages at which infants typically learned to crawl, cruise, and walk changed over the past 3 decades. We compiled archival data from 1,306 infants born between…

How do age and the acquisition of independent walking relate to changes in infants' everyday experiences? We used a novel ecological momentary assessment (EMA) method to gather caregiver reports of infants' restraint, body position, and object holding via text messages sparsely sampled across multiple days of home life at 10, 11, 12, and 13 months…

Recent metascience suggests that motor behavior research may be underpowered, on average. Researchers can perform a priori power analyses to ensure adequately powered studies. However, there are common pitfalls that can result in underestimating the required sample size for a given design and effect size of interest. Critical evaluation of power…

Coordinating a physical movement in time and space with social and nonsocial partners to achieve a shared goal -- "joint action" (JA) -- characterizes many peer-engagement situations that pose challenges for individuals with autism spectrum disorder (ASD). This cross-sectional study examined development of JA capabilities comparing ASD…

Background: The aim of the study was to assess the effect of climbing on static and dynamic balance and to determine the usefulness of such training in supporting the fitness of young adults with mild and moderate intellectual disabilities. Method: The study involved 47 men and 21 women aged 18-25 years. The experimental group participated in…

Due to the lack of tools that can be easily used by practitioners, there is a need to develop acceptable embedded ways to assess children's fine motor skill development within early childhood education and care settings. This study examined the validity and reliability of a brief and ecologically valid fine motor assessment tool for preschool-aged…

A priori power analyses can ensure studies are unlikely to miss interesting effects. Recent metascience has suggested that kinesiology research may be underpowered and selectively reported. Here, we examined whether power analyses are being used to ensure informative studies in motor behavior. We reviewed every article published in three motor…

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…

The development of independent sitting changes everyday opportunities for learning and has cascading effects on cognitive and language development. Prior to independent sitting, infants experience the sitting position with physical support from caregivers. Why does supported sitting not provide the same input for learning that is experienced in…

In this study, the difference between fine motor skills and attention levels of children with mild intellectual disabilities (MID) who get education in inclusive classrooms and special education schools and the relationship between fine motor skills and attention levels were analysed. A total of 176 children with MID between the ages of 9-14, who…

We aimed to calculate interrater reliability of the Test of Gross Motor Development--Third Edition (TGMD-3) after raters reached a consensus regarding measurement criteria. Three raters measured the fundamental movement skills of 25 children on the TGMD-3 at two different times: (a) once when simply following the measurement criteria in the TGMD-3…

The main objective of this study was to examine the existence of Relative Age Effect (RAE) and analyze the effect of gender on Fundamental Motor Skills (FMS) of preschool children aged 4-5 years old. A total of 298 healthy preschool children were evaluated. The Test of Gross Motor Development-2 (TGMD-2) was used to evaluate preschoolers' FMS. The…

This study reports on crawling variability and differences in variability between infants with typical development (TD) and those with developmental delays. This longitudinal study included 0-year-old infants with no apparent dysfunction. The crawling movement in the video was coded objectively with reference to previous research. The infants were…

This study aimed to analyze the effect of the 8-week swimming training applied to secondary school students on their motor skills and 50-meter freestyle swimming ratings. 24 students having swimming license in the age range of 11 to 14 participated in the study voluntarily. Munich fitness test (MFT) protocol was used to determine the motor skill…
