Age-related differences in physical activity levels of young adults

Article Abstract:

This article investigates changes in physical activity that occur with aging. Findings indicate that males participate in more active leisure activities than females across all age groups, but there are significant declines in moderate and vigorous activity participation in both men and women between adolescence and young adulthood.

Current injury or disability as a barrier to being more physically active

Article Abstract:

This article investigates factors that influence physical activity levels in an urban sample of Australian adults. Findings indicate that disabilities and injuries serve as significant barriers to becoming more involved in physical activities and are correlated with both body mass and age.

Utility of pwc75% as an estimate of aerobic power in epidemiological and population-based studies

Article Abstract:

Aerobic capacity and power can be measured by using tests that utilize 75% physical work capacity (pwc) according to age, according to a study of over 1000 men and women between the ages of 18 and 78. Studies often use pwc150% and pwc170%, but results are difficult to extrapolate for older citizens. The pwc75% showed a decline in physical work capacity for older subjects while the pwc150% and pwc170% did not show an expected decline. The pwc75% test should be suited for other studies relating to disease, fitness and aerobic capacity.
