Schoolbag weight and the postural and psychophysical changes in young students: A pilot study

Carriage limits have been established, in order to prevent the risk of musculoskeletal dysfunctions in students. According to recent studies and guidelines, a schoolbag should weigh no more than 10% to 15% of a student’s body weight (BW) (Hong et al., 2000; Hong & Brueggemann, 2000; Whitfield et al., 2005; Bauer & Freivalds, 2009). However, there are several studies showing that this recommendation has not been followed (Whittfield et al., 2005; Murphy et al., 2007; Oliveira et al., 2014).
