The dangers of physical inactivity revisited in 45-year study
Fitness levels have long been known to play an important role in staving off a number of serious illnesses.
At the same time, evidence has been steadily mounting that demonstrates the negative health implications of a sedentary lifestyle.
For instance, a meta-analysis published in the journal Diabetologia in 2012, concluded that:
"Sedentary time is associated with an increased risk of diabetes, cardiovascular disease, and cardiovascular and all-cause mortality."
Similarly, another meta-analysis, published in PLOS One in 2013, measured the amount of daily sitting time and how it impacts on mortality; they concluded:
"Higher amounts of daily total sitting time are associated with greater risk of all-cause mortality and moderate-to-vigorous physical activity appears to attenuate the hazardous association."
Charting fitness and mortality
Against this backdrop of research, the current study approaches the question from a slightly different and more direct angle. In one of the longest studies of its type, published in the European Journal of Preventive Cardiology, researchers investigated fitness levels and their effect on lifespan over the course of almost half a century.
A team - led by Dr. Per Ladenvall from the Department of Molecular and Clinical Medicine, Sahlgrenska Academy at the University of Gothenburg, Sweden - used data from the "Study of Men Born in 1913." In total, 792 men were followed for 45 years. The participants were all 50-year-old men when they were recruited in Gothenburg in 1963.
The researchers designed the study to investigate the risk factors for cardiovascular disease and mortality.
