define the different types of prevention
Prevention - approaches and activities aimed at reducing the likelihood that a disease or disorder will affect an individual, interrupting or slowing the progress of the disorder or reducing disability
Primary prevention - refers to initiatives aimed at healthy people before any risk factors emerge and is designed to prevent progression to disease
secondary prevention - is focused on disease risk factors and the early stage of disease with the intention of stopping further progression
tertiary prevention - refers to actions to prevent progression to complications of disease
Can you explain what the data / findings are showing in key figures (e.g., Paffenberger et al.)
Younger people have lower risk of dying from any cause
Overall mortality rate reduced as the level of PA increased (fitter)
Lower relative risk for older ages with PA
Older people have greater benefit from increasing PA levels
Physically active people have lower risk of dying from any cause at any age (Lee & Paffanberger, 2000)
what is primary prevention
refers to initiatives aimed at healthy people before any risk factors emerge and is designed to prevent progression to disease
what is secondary prevention?
is focused on disease risk factors and the early stage of disease with the intention of stopping further progression
what is tertiary prevention?
refers to actions to prevent progression to complications of disease
what is the most important prevention type?
primary prevention
what is exercise?
activity conducted with the intention of developing physical fitness
what are the two components on physical fitness?
health related - components that have a relationship with good health eg. body composition, cardiovascular fitness, flexibility
skill related - components that have a relationship with enhanced performance and motor skills eg. agility, balance, coordination
what is physical fitness?
physical abilities, attributes that to enable people to perform PA
how to measure BMI?
weight (kg)/height(m)2
