Document Summary

Lecture 1 the relationship between physical activity and heart disease. Physical activity has shaped the evolution of hominids for 6 million years. In developed nations, the last 50 years has seen a shift away from physical activity as a necessity. Evolution has not had time to catch up with the rapid social change. With physical activity no longer a necessity, we must build exercise into our weekly schedule. Physical activity: all leisure and non-leisure body movements produced by the skeletal muscles and resulting in an increase in energy expenditure. Exercise: a type of activity that is planned, structured, and done to improve at least one aspect of physical fitness (aerobic, strength, flexibility, muscular endurance etc. ) Physical fitness: a set of attributes that are either health-related or performance/skill related. Health-related fitness comprises those components of fitness that exhibit a relationship with health status. Performance/skill related fitness involves those components of fitness that enable optimal work or sport performance.
