Abstract

Actigraph is a widely used accelerometer for classifying physical activity levels in
children, adolescents, adults, and older people. The classification of physical activity
levels on Actigraph is determined through time calculations using cut-point
formulas. The study aims to classify physical activity in young children according to
the World Health Organization (WHO) guidelines using accelerometer data and
machine learning methods. The study involved 52 young children (26 girls and 26
boys) aged 4 to 5 years in West Java, with an average age of 4.58 years. These
early childhood physical activity and sedentary behaviours were simultaneously
recorded using the Actigraph GT3X accelerometer for seven days. The data from
the Actigraph were analyzed using two algorithm models: the decision tree and
support vector machine, with the Rapidminer application. The results from the
decision tree model show a classification accuracy of 96.00% in categorizing
physical activities in young children. On the other hand, the support vector machine
model achieved an accuracy of 84.67% in classifying physical activities in young
children. The decision tree outperforms the support vector machine in accurately
classifying physical activities in early childhood. This research highlights the
potential benefits of machine learning in sports and physical activity sciences,
indicating the need for further development.
