“…FMS proficiency was measured using the TGMD-2, a widely-used and validated process-oriented assessment tool with published norms for both object control and locomotor movement skills. In addition, PA was measured objectively using a wearable sensor and the PA outcomes were derived from raw acceleration signal using state-of-the-art machine learning data processing methods [ 27 ]. The application machine learning methods allows researchers to monitor not only the intensity of physical activity, but also the quality of movement behaviors.…”

Background Bronchiectasis is a major contributor to respiratory morbidity and healthcare utilization in children. Children with bronchiectasis exhibit low levels of physical activity (PA) and poor fundamental movement skills (FMS) may be a contributing factor. However, there are no data on FMS’s in this population. The current study assessed FMS proficiency in children with bronchiectasis and examined associations with objectively measured PA. Methods Forty-six children with bronchiectasis (mean age 7.5 ± 2.6 year, 63% Male) were recruited from the Queensland Children’s Hospital, Brisbane. PA was measured using the ActiGraph GT3X + accelerometer. Raw accelerometer data were processed into daily time spent in sedentary activities, light-intensity activities and games, walking, running, and moderate-to-vigorous activities and games using a random forest (RF) PA classification algorithm specifically developed for children. Daily MVPA was calculated by summing time spent in walking, running, and moderate-to-vigorous activities and games. FMS were assessed using the Test of Gross Motor Development 2nd Edition (TGMD-2). Results Fewer than 5% of children demonstrated mastery in the run, gallop, hop, and leap; while fewer than 10% demonstrated mastery for the two-handed strike, overarm throw, and underarm throw. Only eight of the 46 children (17.4%) achieved their age equivalency for locomotor skills, while just four (8.7%) achieved their age equivalency for object control skills. One-way ANCOVA revealed that children achieving their age equivalency for FMS had significantly higher levels of MVPA than children not achieving their age equivalency (51.7 vs 36.7 min/day). When examined by the five activity classes predicted by the RF algorithm, children achieving their age equivalency exhibited significantly greater participation moderate-to-vigorous intensity activities and games (22.1 vs 10.7 min/day). No significant differences were observed for sedentary activities, light-intensity activities and games, walking, and running. Conclusion Children with bronchiectasis exhibit significant delays in their FMS development. However, those who meet their age equivalency for FMS proficiency participate in significantly more daily MVPA than children who do not meet their age-equivalency. Therapeutic exercise programs designed to improve FMS proficiency are thus likely to be beneficial in this population.

Background: Bronchiectasis is a major contributor to respiratory morbidity and healthcare utilization in children. Children with bronchiectasis exhibit low levels of physical activity (PA) and poor fundamental movement skills (FMS) may be a contributing factor. However, there are no data on FMS’s in this patient group. The current study assessed FMS proficiency in children with bronchiectasis and examined associations with objectively measured PA.Methods: Forty-six children with bronchiectasis (mean age 7.5 ± 2.6 y) were recruited from the Queensland Children’s Hospital, Brisbane. Daily time spent in sedentary activities, light-intensity activities and games, walking, running, and moderate-to-vigorous activities and games was measured objectively using the ActiGraph GT3X+ accelerometer. The raw accelerometer data were processed into PA metrics using a random forest PA classification algorithm specifically developed for children. FMS were assessed using the Test of Gross Motor Development 2nd Edition (TGMD-2).Results: Fewer than 5% of children demonstrated mastery in the run, gallop, hop, and leap; while fewer than 10% demonstrated mastery for the two-handed strike, overarm throw, and underarm throw. The mean Gross Motor Quotient of 82.7 ± 12.8 indicated that, as a group, FMS performance was well below average.Only eight of the 46 children (17.4%) achieved their age equivalency for locomotor skills, while just four (8.7%) achieved their age equivalency for object control skills. Children achieving their age equivalency for FMS exhibited significantly higher levels of PA than children not achieving their age equivalency (51.7 vs 36.7 min/day). When examined by the five activity classes predicted by the random forest PA classification algorithm, children achieving their age equivalency exhibited significantly greater participation moderate-to-vigorous intensity activities and games (22.1 vs 10.7 min/day). No significant differences were observed for sedentary activities, light-intensity activities and games, walking, and running.Conclusion: Children with bronchiectasis exhibit significant delays in their FMS development. However, those who meet their age equivalency for FMS proficiency participate in significantly more daily MVPA than children who do not meet their age-equivalency. Therapeutic exercise programs designed to improve FMS proficiency are thus likely to be beneficial in this patient group.

“…Because this study focused mainly on the volume and intensity of the behaviours, it remains unclear whether the observed associations with psychosocial health are moderated or mediated by the other aspects of the behaviours (e.g., types or contexts of PA, content of screen time). Lastly, we acknowledge that the use of intensity cut-points, while validated, may have resulted in some misclassification of movement behaviours as they do not account for upper limb movements during sedentary or stationary light-intensity activities [ 70 ].…”

It remains unclear whether the time-use composition of 24-h movement behaviours (sleep, sedentary time (ST), physical activity (PA)) and recreational screen use are independently associated with psychosocial health. This study examined the cross-sectional and longitudinal associations between 24-h movement behaviour composition, recreational screen use and psychosocial health outcomes in children. Measures completed at baseline (n = 127; 11.7 years) and follow-up (n = 88; 12.8 years) included accelerometer-based 24-h movement behaviours, self-reported recreational screen use and psychosocial health (Strengths and Difficulties Questionnaire, Kessler’s Psychological Distress Scale). Linear mixed models were used to examine the cross-sectional and longitudinal associations between the 24-h movement behaviour composition and recreational screen use levels with psychosocial health outcomes. Overall, the movement behaviour composition (p < 0.05) and recreational screen use levels (p < 0.01) were both cross-sectionally but not longitudinally associated with psychosocial health outcomes. Relative to other behaviours, sleep was negatively associated, while light-intensity PA was positively associated with internalising problems and total difficulties scores. ST was positively associated with internalising problems. High levels of recreational screen use (>2 h/day) were associated with greater externalising problems, total difficulties scores and psychological distress. These findings reinforce the importance of achieving a balance between different types of movement behaviours over a 24-h period for psychosocial health.
