The following year, a review by Brackley and Stevenson stated that the majority of work considered the loads carried by children to be above recommended limits, likewise recommending a maximal load of between 10 to 15% of the child’s bodyweight. This review, while acknowledging that no critical maximal load had been established (to address back pain), recommended around 10% of the child’s bodyweight as a maximum limit.
in 2003 of backpack loads carried by school students during a school day identified that children were carrying as much as 30% to 40% of their body weight. Conclusion: Considering the limited methodological quality and variations in foci across studies, further research is needed to elucidate: (1) the loads students carry around on a school day in their school backpacks and (2) the biomechanical, physiological and physical effects of load carriage on students.Ī review by Mackenzie et al. Students carried on average over 15% of their own body weight, which caused biomechanical and physiological adaptations that could increase musculoskeletal injury risk, fatigue, redness, swelling and discomfort. Results: Twenty-one studies were included, ranging in methodological quality from poor to good (critical appraisal scores 22% to 77%). After relevant studies published in recent years were selected using strict inclusion and exclusion criteria, the studies were critically appraised and relevant data were extracted and tabulated prior to conducting a critical narrative synthesis of findings.
Methods: A systematic search was conducted of the literature using key search terms. The aim of this review was to identify and review studies that have examined impacts of contemporary backpack loads on school children. Background: Backpack loads of school students during school days have been suggested to range from 10% to as high as 25% of their body weight and may have a negative impact on their body.
