Impact of the COVID-19 pandemic on sports and exercise.

Background: COVID-19 is a droplet-transmitted potentially fatal coronavirus pandemic affecting the world in 2020.

It has put many countries in a state of lockdown and sporting events (including the 2020 Olympics) have been affected.

Effects of an Unstructured Free Play and Mindfulness Intervention on Wellbeing in Kindergarten Students.

Play is known as the core occupation of young children as it lays a foundation for their early development and physical, emotional and social wellbeing. Literature suggests that unstructured free play and mindfulness interventions may independently promote wellbeing among preschoolers. However, there is no clear evidence of their combination in supporting wellness in early learning environments.

Physical activity improves mental health through resilience in Hong Kong Chinese adolescents.

Background: Adolescent mental health problems are global public health concern. Primary prevention through physical activity (PA) has been suggested as a potential approach to tackling this problem. Studies in Western countries have provided some evidence of a relationship between PA and adolescent mental health, but the evidence in China is not sufficient.
