Background Age-related changes in attentional abilities can lead to a decline in body segment awareness in space. However, studies have reported that physical activity can improve proprioception among older adults, although proven activities with this potential are limited. Juggling is a promising activity for enhancing proprioception, as it requir...

Background: Negative body image in female adolescents is a sign of the times, but it is also a current global issue due to its implications for the onset of health-compromising behaviours and the increasing power of appearance-based social media. The aim of this study is to investigate the protective role of a life-skills based intervention during...
