“…Data were selected in 60-s epoch lengths to detect spontaneous MVPA in the participants' schools. The cutoff points of Activity Energy Expenditure (AEE) were sedentary behavior (AEE < 0.01 kcal•kg −1 •min −1 ), light physical activity (0.01 ≤ AEE < 0.04 kcal kg −1 •min −1 ), and MVPA (AEE ≥ 0.04 kcal kg −1 •min −1 ) [50]. Accelerometer data were downloaded into Excel files using ActicalReader and Actcal Software 3.12 (Koninklijke Philips Electronics N.V., Amsterdam, The Netherlands).…”

Effects of a Need-Supportive Motor Skill Intervention on Children’s Motor Skill Competence and Physical Activity

A need-supportive environment can provide various motivational benefits to impact children’s psychomotor developmental levels. However, very little is known about the effects of need-supportive motor skill intervention on children’s motor skill competence and physical activity by gender. Guided by self-determination theory (SDT), this study aimed to (a) investigate the effect of a need-supportive fundamental movement skill (FMS) program on children’s FMS competence and moderate-to-vigorous physical activity (MVPA), and (b) explore potential gender differences in these effects. Thirty-six children (63.8% girls; Mage = 6.52 ± 0.97) participated and were divided into two groups: an intervention group (24 need-supportive FMS sessions over eight weeks) and a control group. A repeated-measures multivariate analysis of variance (MANOVA) was used to examine the influence of the motor skill intervention on FMS competence and MVPA over time by group (intervention, control) and gender (boys, girls). The results showed (a) significant group differences between the intervention and control group in FMS competence and MVPA (p < 0.001), (b) non-significant gender differences between boys and girls in FMS competence and MVPA (p = 0.85), and (c) non-significant interaction effects over time (p = 0.52). The findings highlight that a need-supportive FMS program may enhance FMS development and daily physical activity for both genders during the early school years.

“…15 Issues related to cutoff points for classifying levels of physical activity are debated in the literature. In a systematic review, Romanzini et al 19 (2012) suggest that using 1,900 to 3,600 and 3,900 to 8,200 counts/min to identify moderate and vigorous physical activity respectively, in six to eighteen-years-olds, would enable good validity to be obtained. However, other studies, with larger samples, are necessary to represent the reality in Brazil.…”

“…However, they have limitations, such as being dependent on memory and on the interviewers capacity to use them, which can interfere in the accuracy and reliability of the data obtained. 3,7,19 Objective methods, such as accelerometry, are widely used with children. This method, however, does not allow the type of activity to be identifi ed.…”

OBJECTIVE:To assess the validity and operational equivalence of the "Physical Activity Checklist" in children. METHODS:This study complements the cross-cultural adaptation of the Physical Activity Checklist Interview, conducted with 118 school children aged between seven and ten years old, enrolled from the second to the fi fth grades of primary education in the city of São Paulo, SP, Southeastern Brazil, in 2009. The questionnaire enables the quantifi cation of time spent in moderate and vigorous physical activities and sedentary activities and the total and weighted metabolic costs. The accelerometer was adopted as a criterion measure of physical activity. The variables total physical activity (counts/min) and time spent in moderate to vigorous physical activity were quantifi ed. The concurrent validity was assessed by Pearson's correlation coeffi cient while the operational equivalence was assessed by data concerning the duration and evaluation of the interview. RESULTS:The values for the correlation coeffi cient between the results from the questionnaire and the accelerometer ranged from 0.34 to 0.40. It was found that LAF overestimates time spent doing moderate and vigorous physical activity when compared to the accelerometer. The average duration of the interviews was 24 minutes (minimum = 13 min, maximum = 41 min, sd = 5 min). The interview item showing the poorest result was the children's ability to estimate time (poor or fair in 24.8% of interviews). CONCLUSIONS:In relation to the original version, the questionnaire "Physical Activity Checklist" presents similar indices of concurrent validity and operational equivalence, confi rming the appropriateness of the cross-cultural adaptation.

“…A recent systematic review concluded that accelerometers and accompanying physical activity intensity software were feasible for all-day assessment in children and can provide a good indication of the total amount of activity and temporal patterns of activity [ 8 ]. The commercially available software often uses count-based algorithms that sum the data over pre-set time periods (e.g., 15 s), and then uses thresholds to classify this data into different intensities of movement, such as sedentary, light, moderate, or vigorous-intensity activity [ 9 ]. These algorithms were established by comparing activity counts with gold standard energy expenditure measures and have been found to be sufficiently accurate [ 9 ].…”

Given the importance of young children’s postures and movements to health and development, robust objective measures are required to provide high-quality evidence. This study aimed to systematically review the available evidence for objective measurement of young (0–5 years) children’s posture and movement using machine learning and other algorithm methods on accelerometer data. From 1663 papers, a total of 20 papers reporting on 18 studies met the inclusion criteria. Papers were quality-assessed and data extracted and synthesised on sample, postures and movements identified, sensors used, model development, and accuracy. A common limitation of studies was a poor description of their sample data, yet over half scored adequate/good on their overall study design quality assessment. There was great diversity in all aspects examined, with evidence of increasing sophistication in approaches used over time. Model accuracy varied greatly, but for a range of postures and movements, models developed on a reasonable-sized (n > 25) sample were able to achieve an accuracy of >80%. Issues related to model development are discussed and implications for future research outlined. The current evidence suggests the rapidly developing field of machine learning has clear potential to enable the collection of high-quality evidence on the postures and movements of young children.
