Active older adults are more fit

"We found that fitness level had the strongest association with physical activity, followed by gender and season. This means that fit older adults were more active than the unfit, females were more active than males and physical activity was higher in the warmer months of the year. In addition we found that higher education was associated with higher physical activity for males, but not for females. Among other interesting results, we found that the social environmental correlates, such as social support and living situation, were not associated with physical activity among the elderly", says the two first authors of the study, Hallgeir Viken and Nils Petter Aspvik, PhD candidates at NTNU.In the study newly published in the Journal of Aging and Physical Activity, researchers from the K.G. Jebsen Center for Exercise in Medicine - Cardiac Exercise Research Group (CERG) and the Department of Sociology and Political Science at the Norwegian University of Science and Technology (NTNU) Norway have examined how background factors (correlates) are associated with overall physical activity among older adults.

Ever since human beings first began climbing the world's tallest mountains, they have struggled with a basic problem: altitude sickness, caused by lower air pressures which affect the ability of our bodies to take up oxygen. Or, as actor Jason Clarke says in his role as the climbing guide Rob Hall in the recently released movie, Everest, "Human beings simply aren't built to function at the cruising altitude of a 747."
